Chapter 120

But the leaders of Bi University also felt aggrieved.

The research and development of heavy machinery is not that simple. We lack talent, cannot buy good things, and cannot imitate them even if we want to. There are too many things that restrict the development of heavy industry, and all aspects need to be improved.

Without good education to cultivate good talents, and without good equipment to broaden the horizons of engineers, how can good research be carried out by brute force alone?
But this is the situation now, we have to go regardless of whether the conditions are met or not.

bang.

After closing the door, Mr. Bi sat behind his desk and began to review today's documents.

"A smelter needs to be expanded and wants to add workers."

"A machinery factory is short of materials and has been shut down for half a month. It is in urgent need of material supply."

"A large area of ​​iron ore was discovered in a certain place, but the grade is too low. I want to ask whether it should be mined."

The leader of Bi University frowned and reviewed several documents in succession, and none of them was good news.

When they were about to finish reviewing, suddenly one application caught the eye of the Bida leader.

"Application report on independent research and development of hydraulic excavators."

As soon as the leader of Bida saw the title, he felt excited and quickly opened the report to read the contents carefully.

Li Jiandong's writing is vigorous and powerful, and the content is described very concisely.

The leaders of Bida became more and more excited as they looked at it. Regardless of whether this research and development could succeed or not, at least someone was willing to take the initiative to try it.

"Okay, hydraulic excavator, this is the most advanced excavator currently, and Western countries won't sell it to us.

If we can develop it independently, it will definitely greatly speed up the country's construction. I wonder which unit has such an ambition?"

After quickly reading the content, the leader of Bi Da continued to look at the applicant at the bottom.

This sight stunned the leader of Bi University.

"Hmm, it was actually applied for by the steel mill?"

The leader of Bi University thought it was some machinery factory.

After all, heavy machinery such as excavators can only be produced by specialized machinery factories. Although steel rolling mills can also independently produce some mechanical equipment, they can only make some simple and small equipment.

Not to mention that this is not research on ordinary excavators, but hydraulic excavators.

This is a new type of excavator that was only developed abroad a few years ago. Even Western countries have not yet popularized it. Big Brother does have this kind of thing, but our relationship with Big Brother has been a bit unpleasant in the past few years. Although we haven't officially broken up yet, we have begun to be wary of each other.

So when it comes to this kind of advanced equipment, Big Brother is very reluctant and doesn’t sell it to us at all.

It would be a great joy if we could really study what to wear.

But the steel rolling mill wanted to research heavy machinery, which made Bida's leaders hesitate to be happy too soon.

Picking up the phone, Leader Bi was ready to ask Director Yang what was going on.

After a connection, the voice of Director Yang came from the other side.

"Hello, who is it?"

"Xiao Yang, it's me."

"Boss, it's you. What do you want to talk to me about?"

"Hey, I have a research and development application sent by the steel mill. Did you submit it?"

"Oh, yes, it was Li Jiandong who came to me this morning and said he was 100% confident that he could develop a hydraulic excavator. To be honest, I couldn't believe it, but you know Li Jiandong. If he really succeeds, we'll be rich."

Director Yang's tone was a little excited.

If someone else said that they were 100% capable of developing a hydraulic excavator, Director Yang would probably laugh at him and say he was crazy.

But when Li Jiandong said this, Director Yang believed him 80% of the time.

The same goes for the leaders of Bi Da.

Li Jiandong's reputation was built through his repeated research and development.

Before, no one believed that he could succeed, whether it was the hydropower station, the independent steel rolling equipment research and development, or the electric car research and development.

But the fact is, he did it.

Hearing that this was the application he submitted, Bida's leader smiled.

"Okay, okay, if Jiandong said he could develop a hydraulic excavator, then I can look forward to it."

The leader of Bi University hung up the phone and happily wrote the word "read" at the bottom of the application.

Then, he wrote a line of instructions in the instruction column on the right: "All units must fully assist the steel rolling mill, provide them with personnel and equipment, and strive to complete the research and development of hydraulic excavators as soon as possible."

Then he called his secretary and distributed several copies of the document to several heavy industry units.

Let them contact the steel mill and send the people and equipment they need.

at the same time.

Li Jiandong also received a receipt from his superior. Seeing the comments from the superior, Li Jiandong became more confident.

For this era, the technical content of more advanced hydraulic excavators is actually just so-so. Don’t think that Li Jiandong is only a level 4 automotive engineer and a level mechanical engineer.

But don’t forget that the abilities provided by the apprenticeship system include experience for the next few decades.

Hydraulic excavators are very complicated now, but they will be very common in the future. There is no difficulty in researching and developing them. On the contrary, they are more time-consuming to manufacture because they have many parts.

Li Jiandong contacted several machinery factories and recruited more than 20 engineers to work on research and development together.

Among them, Li Jiandong was of course personally responsible for the hydraulic aspect, and for other parts, Li Jiandong only designed a rough outline, and the remaining parts were designed by other engineers by hand.

In today's world without computers, most mechanical designs are done by hand-drawing.

This is one of the reasons why Li Jiandong needs so many engineers. If there are not enough people, how long will it take to hand-draw so many parts?
The entire process, from submitting the application to forming the R&D team, took only three days.

While all the engineers had not yet arrived, Li Jiandong asked the transportation team to select talents and set up a special excavator operation team.

Li Jiandong's excavator has not been built yet, but he spent a day in advance to make a simulated control panel with the operating levers exactly the same as those on the excavator.

In this way, the excavator can be put into use immediately after it is built.

"Old Li, I finally waited for you."

That day, Li Jiandong was busy until very late and came back home.

As soon as I stopped, I saw Yan Bugui walking out of the house wearing shorts and holding a palm-leaf fan.

"What's wrong, Old Yan? Do you want to talk to me about something?"

Li Jiandong asked with a smile.

He has been working overtime every day these days, but he doesn't feel tired at all. Instead, he feels very fulfilled.

It feels wonderful to be able to live in this era and contribute to national construction, and Li Jiandong also feels a great sense of accomplishment.

These days, he doesn't come back until nine or ten o'clock every night.

The fact that Yan Bugui could wait until now must be something big.

It's just that he overestimated Yan Bugui a little. For Yan Bugui, money and making money are the top priorities.

He just smiled and said to Li Jiandong: "Lao Li, I heard that your factory has set up a new excavator team.

This should require a lot of workers, right? Look, my son Xie Fang is already sixteen years old this year, why don’t we let him learn it too?”

Li Jiandong understood that Yan Bugui, the stingy old man, was planning this.

The excavator team at the steel mill does need a lot of people, although for now they are all part-time workers from the fleet.

However, the fleet’s transportation mission is also very heavy, and we will definitely need to recruit more people to fill this vacancy.

As Li Jiandong's apprentice, Yan Jiecheng is responsible for training new people in this excavator class.

It was obvious that Yan Bugui had already contacted Yan Jiecheng, but Yan Jiecheng was afraid that he could not make the decision, so he asked him to contact Li Jiandong.

"Okay, tell him to go find Jie Cheng tomorrow and tell him that I agree."

Li Jiandong agreed immediately, and before Yan Bugui could thank him, he said,
"However, the issue of workstations depends on the street allocation. I can only help him arrange a temporary worker first."

Yan Bugui knew it well, and he smiled and said:

"Don't worry, Lao Li. It's good to have a temporary job. With you in the steel mill, this temporary job is like a stable job."

Li Jiandong rolled his eyes, but what Yan Bugui said was not wrong.

Temporary workers do not receive as many benefits as regular workers, and their job grades cannot be increased.

However, the initial salary is still relatively substantial, at least it is much more profitable than doing odd jobs for others.

Many leaders in the steel rolling mill have arranged their family members to work in the security patrol team, which is also a kind of temporary work. The only advantage is stability. Now operating an excavator is the same as joining the patrol team, and it is a technical job, so maybe you can get a regular job in the future.

After all, it is indeed easier for skilled workers to become regular employees than those in other occupations.

After returning home, Qin Huairu didn't sleep either.

She waited for Li Jiandong to come back every night, opened the door for him, and helped him wash up.

After being reminded by Yan Bugui, Li Jiandong also thought that he could take the opportunity to arrange a few temporary workers to the steel rolling mill.

So, he said to Qin Huairu, "Huairu, if you are free these two days, go home and ask if there is anyone at home who wants to work as a temporary worker in the steel mill."

Qin Huairu was a little excited when she heard this.

Who doesn’t want to move to the city these days?

Even if it is a temporary job, it is better than farming in the countryside. After all, temporary workers are also workers and they also have wages, and not a small amount.

So, without thinking, she said:
"Brother Jiandong, is the steel mill hiring temporary workers? How many can you hire?"

Li Jiandong thought for a moment and said, "There are quite a lot of requests, but we can't take them all. Go back and ask around and arrange for two people who are close to you first."

Qin Huairu's family is Li Jiandong's family, so it's okay to help if you can.

But, if the relationship is not that good, then forget it.

Temporary workers do not have dormitories, but city dwellers who work as temporary workers can go home and live there.

For people who come from the countryside, where to live after work is also a problem.

If there are two or three people, Li Jiandong can still help them find connections and make arrangements. But if there are more people, it is not very convenient for Li Jiandong to ask for this.

"Okay, I'll go back tomorrow."

When he woke up, it was already the next morning. Li Jiandong had been busy with work these days and slept well.

Qin Huairu had already prepared breakfast and was packing things to take home. Now her eldest son was already in school, and her second and third sons were still in kindergarten, so she only needed to take her little girl home, but her free hands could not be idle, as she had to take some things home.

This is a bit troublesome for a man who is a leader. He has to bring a lot of things home every time.

Otherwise, people would gossip about her, such as whether her husband made a mistake and was fired? Does he look down on her family? Does he do this or that?
Although I know it's just gossip, it sounds uncomfortable.

Giving money or tickets is not enough. Even if others can't see it, they will still gossip about it. Even if you are a strong person, you will feel depressed when encountering such things.

Therefore, every time Qin Huairu returned home, she would carefully prepare something to shut those people up.

After dinner, Li Jiandong went to work at the steel rolling mill.

Chang Hanqing is here today too.

He studies buses and trams and doesn't know much about excavators.

This time, I came here mainly to learn from Li Jiandong about the research and use of hydraulic equipment. In the future, these things can be put on buses.

"Master, where did you research the hydraulic equipment? When I was abroad, the team next to me was also researching this. It is said that the principle of that thing is simple, but it is very difficult to make it."

Chang Hanqing asked somewhat excitedly.

He probably knew more about hydraulic equipment than any other engineer in a machinery plant, after all, he had seen it with his own eyes.

Li Jiandong smiled and said:
“You think it’s simple because you haven’t studied it in depth. In fact, hydraulic equipment is not simple at all. The precision of the components alone requires very high standards. If the sealing is slightly poor, oil overflow or air leakage will occur.

There are also other issues such as throttling speed regulation, oil return back pressure, low-frequency oscillation, overflow valve overflow, etc. If any of them is not done properly, it will cause component damage. Precision and durability are the most difficult aspects of manufacturing hydraulic equipment."

Hydraulic equipment does look simple, just like syringe injections are based on the hydraulic principle.

However, when the pressure of this equipment reaches a certain level, the design and manufacturing requirements of the components will become very high.

Li Jiandong just casually mentioned a few difficulties in production. In fact, there are far more difficulties than these if you want to complete the research and development of hydraulic equipment.

Otherwise, it wouldn’t have taken so many years to develop.

Finally, it was during the period of reform and opening up that this problem was gradually overcome by introducing foreign equipment.

If Li Jiandong can develop a reliable hydraulic system, at least in this regard, domestic technology can be advanced by more than ten years.

While Li Jiandong was explaining to Chang Hanqing, his own experience was also increasing a hundredfold.

On the other side, Qin Huairu got off the bus, carrying her daughter Li Xunhua on her back, and holding some food and daily necessities in each hand.

It's already past nine in the morning and the weather is starting to get a little hot.

People working in the fields also carried their tools back to the village, sat under big trees or other shady places, and rested while waving palm-leaf fans.

Seeing Qin Huairu coming back alone, the villagers immediately perked up and asked:

"Qin Huairu, why did you come back alone? Where is your man?"

"Yeah, doesn't your man have a car? Why does he let you bring the child back alone? Isn't that too irresponsible?"

"Qin Huairu, you didn't quarrel with your man, so you went back to your parents' home?"

The people who were talking were a few women. They loved gossip, and the more unlucky a family was, the happier they were.

Qin Huairu is the only one in the village who married into the city, and her husband is a senior manager of a steel mill.

They had been jealous of such good conditions for a long time, and when they saw Qin Huairu coming back alone today, they immediately became excited.

Qin Huairu knew these women very well. She had heard them talking about others behind their backs since she was a child.

She knew that they were definitely hoping that she would suffer misfortune, but she didn't care too much.

"Aunt, my brother Jiandong has been busy with work recently and has no time. I was just bored, so I came back to visit."

"Oh, how can a married woman just go back to her parents' home casually? Especially if you come back alone. If someone who doesn't know sees you, they will think you two are divorced."

“Huai Ru, it’s not easy for you to marry into the city, and you found such a capable man.

You have to keep a close eye on him, lest someone else snatch him away."

“Second sister-in-law is right, everyone likes good men, but some shameless women don’t care whether they have wives or not.

Men like the shape of their heads, Qin Huairu, you have to be more careful."

Qin Huairu felt helpless after hearing these words. These were the women in their village. It was rare to hear anything good from them.

However, Qin Huairu did not intend to argue with them. People like them were unhappy with their lives, and all they could do was to have fun.

Qin Huairu is living a good life, why should she argue with them?
So she just politely agreed twice and continued walking home.

When I got home, Qin Dashan and Wang Shiyan had just returned from the fields. Their village is relatively close to the Miyun Reservoir.

Although there is a severe drought, there is no shortage of irrigation water, and the situation is much better than those remote villages.

At this moment, seeing Qin Huairu coming back, Qin Dashan and Wang Shiyan were also very confused.

"Huai Ru, why did you come back alone? Where's Jian Dong?"

Wang Shiyan asked a little nervously, thinking, could there be some conflict between the couple?
Seeing her mother's nervous look, Qin Huairu quickly told her the purpose of her return.

When they heard that the steel mill was recruiting temporary workers, and those who were skilled in the field, Wang Shiyan and Qi Dashan became excited.

Although there is no shortage of water in their fields and it will not affect the harvest, who would be willing to stay in the village when they can go to the city?
In the city, the monthly salary is at least 10 yuan, and in the village, saving cents for a year can only exchange for 20 or 30 yuan.

Moreover, there are no quotas or tickets in the countryside, so many things you want to buy are not available.

After Qin Dashan found out about the steel rolling mill's employment requirements, he began to discuss with Wang Chunmei who should be the temporary worker.

The couple are old, and there is so much land at home, and Qin Dashan is still the team leader of the production team and cannot be left without him.

After discussion, it was decided to let Qin Huairu's two younger brothers go to Li Jiandong.

Qin Dashan went out to find his brother to tell him the good news, and on the way he passed by the place where the women were enjoying the cool air.

As soon as these women saw Qin Dashan coming, they wanted to continue asking Qin Huairu whether she had a quarrel with Li Jiandong.

Qin Dashan replied to them coldly:
"You know nothing. Jiandong is the deputy director of the steel mill. Do you think he is just like you guys, with nothing to do all day and only knows how to gossip about other people's private lives?"

"Then why did your daughter go back to her parents' home alone? Can't she just stay in the city?"

"Haha, my daughter is here because there is good news. The steel mill is looking for temporary workers to learn how to operate an excavator. The monthly apprentice salary is 20 yuan, and if you do a good job, you will have the opportunity to become a regular employee. Do I need to tell you this?"

Qin Dashan had long wanted to scold these bad-mouthed women.

I finally got the chance today, don’t be too relieved.

When the women heard that Qin Huairu had returned to the village for this matter, they immediately became jealous and angry.

When the villagers heard that the steel rolling mill was recruiting temporary workers or skilled workers who had the opportunity to become regular employees, they were very envious.

Even the village chief went to Qin Huairu's house to congratulate him, hoping to establish a good relationship with him. Maybe next time he gets a chance, he can get some benefit from it.

the other side.

The cadres in the steel rolling mill are also showing off their talents. Although he is just a temporary worker, this is a technical job. Even the security patrol team that has almost no chance of getting a regular job has so many people eyeing him, let alone an excavator driver.

While eating, He Daqing found Li Jiandong.

"Lao Li, my senior brother's child is sixteen years old and still unemployed. He wants him to come to our factory to learn how to drive an excavator. Do you think it would be possible to let him come and try?"

"Sure, if he wants to come, just give it a try."

Liu Haizhong also came over:
"Deputy Director Li, my Guangtian is also sixteen years old this year."

"Oh, it's so bright in the daytime?"

"Yes, just sixteen years old, about the same age as Xie Fang."

"I heard that Guang Tian is not very good at studying. He can drive an excavator, but he can't be so careless anymore."

There were other people who also came to look for Li Jiandong while he was eating.

Otherwise, after finishing his meal, Li Jiandong would go back to work, and would not see anyone except Director Yang and the group of engineers.

The first batch of excavator workers consisted of fifty people.

Among them, 10 were transferred from the fleet, and the remaining 40 were temporary workers.

Yan Jiecheng was responsible for teaching them how to operate the system. Although he was not recruiting disciples, he also triggered the reward for teaching.

Within a few days, Li Jiandong's excavator operation skills had reached the maximum level.

At the same time, you will acquire a unique skill: human-machine integration.

Any machine control can be done with ease.

Probably because this skill is too easy to upgrade, so the ability of the unique skill is quite average.

Although it is not as good as dynamic vision and other special skills, it is better than nothing.

Li Jiandong is going to make hydraulic equipment next, and the most important thing is precision.

He has pixel eyes, so he has no problem observing details, but if his hands are not operated properly, errors will still occur.

Now with the integration of man and machine, operation is no longer a problem.

Facts also proved Li Jiandong's judgment.

Others failed in their attempts to manufacture key components for hydraulic equipment several times, but Li Jiandong succeeded at once by using his unique skills of pixel eye and human-machine integration.

Although there is only one, once it is made and the mold is available, the rest will be easy to solve.

It took fifty-four days.

The first domestically produced hydraulic excavator was finally fully assembled.

Li Jiandong personally operated the excavator and performed several routine excavation actions in succession. The excavator ran very smoothly and was operated continuously for more than ten minutes.

Li Jiandong even deliberately made some rough movements, but the excavator still did not malfunction.

This made the workers and engineers present very excited. They actually made the world's leading hydraulic excavator.

Not only is it much smaller in size, but its digging efficiency is several times higher than that of a mechanical excavator.

The engineers who were originally somewhat dissatisfied with Li Jiandong were convinced after seeing the finished product.

"It should be about time. Go inform Director Yang."

Li Jiandong jumped off the excavator and gave instructions to an engineer.

The experiment just now was very good, the excavator's performance was qualified, and the next step is mass production.
