Siheyuan: My Northeastern Farmhouse

Chapter 223 Fighter in the Engine

What is the direction of designing agricultural machinery yourself? It must be miniaturization!

why?

I especially liked the video content of Professor Wen Tiejun in later generations, and I also bought and read the book "Eight Crises".

According to Professor Wen's explanation of People's Communes from an economic perspective, People's Communes also bear the need for the country's industry to be sent to the countryside!

The tractors, combine harvesters and other industrial products our country imported from the Soviet Union cannot be exported due to technical reasons. So what is the way out? It can only be digested by domestic rural areas!

Otherwise, who would you produce and sell it to?

How to digest and upgrade technology without production?

Therefore, at this time, the domestic agricultural machinery was all imitation of the Soviet Union's stupid, thick and thick products, suitable for large-scale operations, and because of the price factor of these industrial products, they could only be purchased on a people's commune basis!

Rural grassroots units, brigades or squads simply cannot afford it! Not applicable either!

Therefore, by the 80s, when delivering grain in rural areas, livestock was still used mostly as transportation capacity!

Therefore, after household contracting was implemented in the 80s, taking the Dongfanghong tractor in Shanghai as an example, the output dropped from tens of thousands of units a year to a few thousand units in an instant, resulting in direct losses!

Most other industrial production plants are like this too!

And small agricultural machinery took off instantly, reaching the level of annual demand of one million!

Small agricultural machinery is made by farmers who carry single-cylinder diesel engines to agricultural machinery stations and ask technicians to process them!

Moreover, Professor Wen also talked about something. In order to obtain loans from the World Bank in the 80s, our country carried out domestic transformation in accordance with the rules and requirements of the World Bank!

Therefore, I asked Qian Weichang to design a single-cylinder diesel engine. Following this direction, designing small agricultural machinery by myself can fill a gap in the country!

With the single-cylinder diesel engine, an artifact of domestic rural areas, other agricultural machines are not just at your fingertips!

Have you never eaten pork or seen a pig running?

When a tractor is connected to a plow, it becomes a cultivator; when connected to a rice transplanter and a seeder, it can sow; when connected to a harvester, it can be harvested!

By the way, I also need to draw an irrigation system, this is easier!

By the way, should I also build a farm tricycle? Isn't this just a two-wheeled bucket behind a motorcycle?

Yes, I promised Zheng Chao to design a motorcycle before?

Keep copying! I am copying Suzuki’s TR125? Or copy Honda's CG125? A two-stroke, a four-stroke?

Nonsense, what are you thinking about? Of course adults want them all!

It’s a pity that I haven’t started painting the motorcycle yet, it’s coming up on Saturday!

Without even going to the Jingcheng Pharmaceutical Factory, Gu Weijun put the thick stack of 493 engine drawings he had drawn into his schoolbag, checked and sorted the numbers again, and went to Shijingshan to find Qian Weichang in high spirits!

Gu Weijun wasn't trying to show off, was he that boring? What a low-key person you are? Our main purpose is to promote the development of our domestic industry!

Of course, if the fat old man discovered his talent in this area and was proud of it, that would be a different matter!

It is also a blessing for you to accept me as your student! Fat old man!

Cherish it!

March 3th is a day worth remembering. Scientist Gu Weijun officially entered the domestic scientific research stage!

Hey, the fat old man and the others are not in the office? Are you still in the casting shop? Is there still something wrong with the hydraulic press column that was cast last time? With doubts, Gu Weijun strolled over casually.

In the casting workshop, the fat old man, Li Youshan, Director Zhou and others all wore safety helmets and held the drawings in their hands. While discussing loudly with the heavy industry engineers and casting masters, they watched the red molten iron pouring into the ground. In a huge mold.

Before the molten iron could cool down, workers nearby began to stir it with graphite rods!

Taking advantage of the fat old man's break, Gu Weijun immediately took the teapot next to him and handed it to his beloved teacher.

The fat old man was stunned. His beloved disciple came so early today? He took a sip from the teapot and asked casually, "How's the diesel engine doing?"

"Is there anything you don't understand?"

With a smile on his face, Gu Weijun took out the drawing of the 493 engine and handed it to the fat old man with both hands. "Teacher, after reading the drawing of the 6160 engine, I suddenly had an inspiration. It just so happened that the jeep I was driving was not powerful enough. , designed such a four-cylinder diesel engine!” ˆ ˆ ˆ “Please correct me, teacher!”

What? Are you so inspired? From marine engines to cars? Qian Weichang doubtfully took the drawing and looked down at it carefully. What he saw was so incredible that he was stunned!

What is this? This is? Could this be designed by his own disciples?

From a structural point of view, there is no problem at all!

Qian Weichang reached out directly to Gu Weijun, "Give me all the drawings!"

Gu Weijun quickly took out a thick stack of drawings from his schoolbag and handed them to Qian Weichang.

Qian Weichang quickly looked through several main structures. Judging from the major structures of this diesel engine design, there is no problem at all? And there are still a few structures that I have to study carefully later! Very interesting!

Qian Weichang once again wondered, was this really designed by me, a student?

Is this a burst of inspiration or an explosion?

Qian Wei grew numb and looked up at Gu Weijun. He was still thinking about the fuel system in the structural drawings, and his eyes gradually lost focus.

Damn it! Nothing will happen to the fat old man, right? Is this your own blueprint that has made you doubt your life?

"Teacher? Teacher?" Gu Weijun quickly shook his hand in front of Qian Weichang's eyes and raised his voice at the same time!

"What are you yelling for?" Qian Weichang came to his senses and scolded Gu Weijun unhappily. He had just had some ideas about the fuel system when he was interrupted by the unfilial student in front of him!

Qian Weichang thought for a few seconds and then turned to look at Wu Zhonghua and Li Youshan who were discussing the hydraulic press drawings, and shouted: "Old Wu, Old Li, you two come here quickly!" Then Qian Weichang's eyes were locked on this picture again On the side structure diagram of the 493 engine!

At the same time, my mind was spinning at high speed again, constantly analyzing the structural problems of this engine!

"Old Qian, what's wrong?" Hearing the shout, Wu Zhonghua and Li Youshan hurried over, thinking that it was Qian Weichang who discovered something went wrong during the casting process!

Li Youshan asked hurriedly: "What's wrong with the casting process?" Is it going to fail again this time? The casting process has been optimized several times in the past two weeks! Just a little bit closer, the 2-ton hydraulic press can be officially manufactured! Li Youshan is the most urgent here, and he is leading this project!

"It's not a problem with the casting of the pillars!" Qian Weichang shook his head, with an indescribable expression, shocked? happy? Pity? Lost? He handed them the side structural diagram of the diesel engine assembly, "Look at the structural design diagram of this four-cylinder diesel engine!"

Li Youshan was stunned for a moment, and Wu Zhonghua took it. When he lowered his head and looked at it, he couldn't help but say "Hey!". After a while, he exclaimed: "Old Qian, what a beautiful design!"

"Old Qian, when did you secretly design such an excellent diesel engine?" As a master of internal combustion engines, Wu Zhonghua has a say in this aspect. He mainly studies fuel engines for aircraft, such as the J-6 .

Qian Weichang did not answer and looked at Li Youshan.

Li Youshan quickly took it from Wu Zhonghua's hand and looked at it. A few seconds later, he also exclaimed: "Hiss!"

“What a wonderful idea!”

“What an exquisite design!”

When Qian Weichang called out to Wu Zhonghua and Li Youshan just now, Director Zhou and Secretary Huang both had their hearts in their throats, thinking that there was something wrong with the casting! But don’t fail again!

What turned out to be Qian Weichang was talking about a design drawing of a four-cylinder diesel engine. The two looked at each other. How important is the casting of the 2-ton hydraulic press column? Why are you looking at a diesel engine?

Besides, hasn’t the single-cylinder diesel engine been successfully developed? Has this started the development of four-cylinders? Even if it starts to be developed, it is not as important as casting the pillar now, right?

After hearing the same exclamations from Wu Zhonghua and Li Youshan, Director Zhou and Secretary Huang opened their eyes in disbelief. What day is it today? Why are the credits jumping out one by one?

The two people asked loudly in unison: "Is this drawing of a four-cylinder diesel engine really so good?"

The two looked at each other and shouted at the same time: "Who designed it?"

"Can it be produced?"
