Siheyuan: My Northeastern Farmhouse

Chapter 225 Take the road!

As expected, Gu Weijun had three completed drawings on his desk, which were very thin compared to the design drawings of the diesel engine.

However, Qian Weichang and Wu Zhonghua did not feel that something was wrong, but were shocked again!

Could it be that Gu Weijun actually designed three types of agricultural machinery?

Whether the design is successful or not is not said for now, but the high output of this designed industrial machinery alone is enough to prove Gu Weijun's talent in this area!

Qian Weichang and Wu Zhonghua took a look at the structural diagrams of the seeder assembly and the rotary tiller assembly respectively. Huh? Is the structure very simple?

But it seems very practical, right? You can’t design it if you haven’t planted it before!

Glancing at Gu Weijun in surprise, Qian Weichang asked: "Are they all small agricultural machinery?"

"Why not design a large one?"

Gu Weijun replied: "Teacher, large agricultural machines are all researched and produced by specialized agricultural machinery factories!"

"I am mainly targeting agricultural machinery at the rural brigade or small team level! Let them afford it and use it!"

"And these two agricultural machines are also particularly suitable for irregular plots in rural areas, places that large cultivators cannot take care of!"

"Well, it's very thoughtful!" Qian Weichang nodded in approval and picked up the design drawing of the water pump. This one is simpler, just a single-cylinder diesel engine plus a water pump! After putting the drawings away, he asked again: "Has the structure been calculated?"

"Teacher, we have calculated everything, including the structural pressure and the tension of each part of the parts!"

"Secretary Huang," Qian Weichang pointed to the three drawings, "We will not test these agricultural machinery. After you give the drawings to the machine repair shop for processing, you can take them directly to Hongxing Commune for use!"

“The structures are simple and very suitable for rural use!”

"Since Gu Weijun has done the structural calculations, there should be no problem!"

"Haha, okay!" Secretary Huang was just about to tell Secretary Miao to take the drawings to the machine repair shop. Liu Feng, the director of the machine repair shop, rushed over with two master workers. As soon as he entered the office, he shouted enthusiastically: "Secretary Huang, We are fully cooperating!”

Can you not be enthusiastic? In the past, the machine repair shop mainly repaired various equipment in the steel plant. I can't say it was dirty and tiring, but it was about the same! Still can't stand out the results!

It's great now! Director Zhou first developed several single-cylinder diesel engines, and also took care of the Ministry of Metallurgy and the Ministry of Agriculture. The machine repair shop can make great strides in development!

Now a four-cylinder diesel engine suddenly appeared. Liu Feng was even more excited than Director Zhou. Am I still the director of the machine repair shop? No, it’s the director of the machinery factory!

I am not just engaged in machine repair and logistics! I am producing tractors now, but I will produce cars in the future!

"Hey! Old Liu, you came just in time!" Secretary Huang enthusiastically called Director Liu Feng to the table, "There happen to be three newly designed agricultural machines here, and the drawings are all correct after calculation! I want to invite you The machine repair shop will hurry up and produce it, and it will go directly to the Red Star Commune next week to put it into use!"

Liu Feng was stunned. Isn't it a four-cylinder engine? Why did it become agricultural machinery again? He suppressed his doubts for the time being, took the drawing handed over by Secretary Huang, and gave it to the two masters who came with him, "Master Zhao, Master Liang, please take a look at it!"

After looking through it, the two masters nodded, "There will be no problem in producing it. I guarantee it won't delay next week's spring plowing!"

Only then did Liu Feng look at Secretary Huang and asked: "Secretary, didn't you mean a four-cylinder diesel engine?"

Secretary Huang pointed at Liu Feng, "Haha! Don't worry! Dajun, take out the engine drawings and let Masters Zhao and Liang take a look at them first!"

When the two masters got the drawings and looked at the processing parameters, they were surprised. The structure is so exquisite and the required precision is so high! And there are so many parts! Master Liang directly asked Liu Feng to join us: "Director, Lao Zhao and I are too busy to process these parts!"

"Hurry up and call our apprentices from the clamp repair shop!"

Being treated as an errand boy by Master Liang, Liu Feng was not impatient at all, "Okay, Master Liang, Master Zhao, you two will discuss the processing details with a few scientists first, and I will go get them here now!"

The group moved to the test workshop, where Qian Weichang, Wu Zhonghua and two masters communicated and answered the questions about the components after dividing the 493 engine design drawings into systems. The test workshop of Shijingshan Iron and Steel Plant, which can actually be called a test plant, occupies a very large area. The first generation of oxygen top-blown converter was developed here.

The various supporting facilities here are very complete. In addition to small electric steel furnaces, there are also various machine tools such as pliers, milling, planing, and turning, as well as metal condensation such as annealing, cooling, and extraction.

After the apprentices arrived, two masters, Liang and Zhao, took several apprentices to confirm the dimensions and requirements of the parts in the drawings again, and then started making sand molds and grinding the parts!

This time, Gu Weijun was not sent by Qian Weichang to do data calculations. Instead, he was asked to polish the parts with several masters. In his words, how could he not participate in the first engine he designed?

For a designer, every product is equivalent to his own child, and he must understand and understand it again.

Gu Weijun regarded it as if he was taking a metalworking class, especially since he was a designer himself. He knew the dimensional parameters of the parts well and had an eye for machining and marking.

Not only Gu Weijun, but also Qian Weichang and Wu Zhonghua also joined in the production of parts, because they also wanted to technically verify some designs of this engine through physical objects!

The paper data of the 493 engine is so good, and with the endorsement of several scientists such as Qian Weichang and Wu Zhonghua, everyone is full of expectations for this engine.

The anticipation is wonderful, but the waiting is long. In the next week, Gu Weijun will go to the test workshop every night to process the parts and assemble them together!

Finally at 4 o'clock in the evening on April 3, after discarding countless cylinders and parts, the engine was finally assembled!

Before it was started, everyone gathered around this 493 engine and kept sighing, how beautiful it is! The beauty of machinery!

"Come on, connect it to the gearbox, let's do a test quickly!" In order to test, Qian Weichang directly removed the 4-speed gearbox of Gu Weijun's Willys Jeep parked at the door of the workshop.

"Turn on!" Following Qian Weichang's command, Gu Weijun pressed the switch from a distance, only to hear, "Buzz!"

The sound of the 493 is also very nice after it is started. It does not make a "rumbling" sound and black smoke like other diesel engines, but a very low "buzzing sound!"

"Change the speed!" After hearing Qian Weichang's instructions, Gu Weijun gradually changed the speed, from 1st gear to 4th gear, "Buzz~~" The faster the engine speed, the smoother the engine, and the lower the sound!

Or else, hand-built cars are expensive?

Originally, Gu Weijun thought that after this engine was built for the first time, there would be some problems, such as excessive gaps, discrepancies in the size of parts, etc.! Unexpectedly, this eighth-level master and his apprentices did a particularly perfect job!

The sound of the engine is smoother than the Jiangling pickup truck I drove later!

What are you waiting for?

Hurry up and trick a few masters into helping you install it on your Jeep! "Come on, Master Liang and Master Zhao, help load it into the jeep, and I'll drive on the road to experience it!"

I'm really waiting for Director Zhou to come and grab it!

After installation, Gu Weijun started it, simply applied oil, and the feeling of pushing the back was there!

"Teacher, let me test the running conditions on the road!" As Gu Weijun shouted, Willis, whose heart was changed, accelerated instantly and ran directly to 100 yards before disappearing in a flash.

Director Zhou, who came after hearing the news, slapped his thigh directly, "I agreed to test it!"

"You brat doesn't have martial ethics!"

"You brat, are you so ignorant? If I, Old Zhou, don't put on some small shoes for you, you won't know that Lord Ma has three eyes!"

Director Zhou rubbed his hands excitedly, "Scientist Qian, this engine should be successful, right?"

Qian Weichang's eyes were filled with relief, and he answered firmly: "That's right! From just starting to accelerating, the power runs smoothly, which proves that this design is very successful!"

"When Gu Weijun comes back from the road test, we can do more tests!"

"I have a hunch!"

"This engine will definitely bring domestic engine manufacturing to a whole new level!"

Hearing Qian Weichang's sonorous and powerful words, everyone in the test workshop felt proud! Factory Director Zhou couldn't hold back his joy and said to Secretary Huang: "Old Huang, please arrange for the masters to make a few more units!"

"It can be said that we have a double happiness today!"
