Chapter 199 Assembling the Excavator (Third Update)
Before dawn on Sunday, the doors of the motorcycle factory were opened, and four different vehicles drove out of the factory gate.

Liu Hai drove the factory manager's car. Li Bing, the head of the logistics section of the rolling mill, the accountant in the factory, and the logistics section chief of the motorcycle factory, and the accountant, each took a bag of money and sat in the car.

On the side of the township government, many people are waiting in the farmland beside the road. Behind these people are hills of cabbage, all covered with straw.

As soon as it dawned, I saw cars of Sibuxiangs suddenly appearing. Li Bing and the accountant from the steel rolling mill got out of the car. Some workers got off from the Sibuxiangs behind them. These workers worked overtime for free today in exchange for being able to bring back a sack of cabbage.

Liu Hai took several cars and drove to the sunbathing area in his village.

No one came from the motorcycle factory. After all, Liu Hai belonged to his own village. Li Bing brought the workers here for safety.

Cabbages and radishes are piled up around the drying yard.

"Captain, put the sacks first, and then weigh them." Liu Hai asked people to drop bundles of sacks, and said.

"Okay, you all watch carefully, don't go along the sack." The captain yelled loudly.

The members began to pack radishes, and it was obvious that the radishes were very good.

While loading, weighing, and getting into the car, Liu Hai stared at it, so don't make yourself embarrassed.

Soon a car was loaded. This thing said three tons, but at least five tons. After all, the roads were good.

At noon, the team killed chickens and made roast chicken and steamed buns.

There were more than [-] cars in his team, and several cars ran back and forth several times. The captain squinted his eyes while holding the money, and the cabbage was peeled relatively well.

"Uncle, I'm leaving first." Liu Hai didn't have time to go home, so he sent the accountant and others back first.

"Okay, okay!" The captain was very happy. This is all money, a total of 10,000+ catties.

10,000+ kilograms sounds like a lot, but it’s actually not that many tons. Even a modern large trailer can haul tens of thousands of kilograms, but this time it’s a lot.

This side of the village is almost the same. Liu Hai waited for another hour and ate here. Before leaving, the village also sent chickens, eggs and so on. Everyone has them, and those drivers also have them.

Only Liu Hai didn't drink, and the rest drank, even those who didn't drive like crazy. It's common to drink and drive at this time.

When Liu Hai returned to the factory in the evening, he didn't plan to go home. It was very comfortable to live in the laboratory with the heating. He could just go back to the courtyard occasionally.

The next day, Liu Hai reported the situation of harvesting cabbage in detail. Sun Aiguo heard that there was only a little cabbage, and said: "This is not much. Our factory is expected to exceed 1 people next year, but Xiao Liu, don't take the initiative to favor these favors." Give, even if you give, don't promise once, you know, if you give too easily, others will feel that you don't have much affection."

"Thank you, director, thank you, director."

"How about your four-cylinder diesel engine?"

"It has already started to be manufactured, and the difficulty is not too great."

"That's fine, that's fine.

Sun Aiguo didn't have time to say anything to Liu Hai. He was leading people to attack the boring machine. There are many technologies in the boring machine, mainly heat treatment technology.

Under Liu Hai's suggestion, Sun Aiguo established a special heat treatment workshop. This workshop is kept secret from the outside world, and it is divided into many processes. The heat treatment process will also fail.

In addition, you can also make some specious additives or something, anyway, the real and the fake come together.In later generations, we sometimes go to visit other people's factories, and other people just mess around. At worst, after the person leaves, they can do it again according to the correct method.

It's December. Liu Hai counted on his fingers and realized that Wang Hongmei's life should be approaching soon. Giving birth to a child in this era would mean death. When Liu Hai was almost ready, he would go back a few more times. Anyway, he now owns all kinds of cars.

The casting of a four-cylinder diesel engine is much more difficult, but it is not as abnormal as a large diesel engine. The process technology of a large casting is very complicated, and there are too many temperature variables in it. If one is not mastered, it will be useless.

The four-cylinder one was better. Liu Hai and Li Dali and three others cast the cylinder block. The first time it was cast, it failed. This was the second time.

When it was cast for the second time, Liu Hai checked it carefully and found that it was qualified, and then it was followed by processing.

"Section Chief, what are we doing here?" Li Dali and the other three thought they were also making cars, but the more they worked, the more they felt something was wrong. What's wrong? The tracks are all out?

Hearing Li Dali's question, Liu Hai said, "A kind of construction machinery, don't ask, hurry up and do it."

"Okay." In the impression of Li Dali and the others, the only thing with tracks seemed to be the legendary tank.

Not only Li Dali and the others are a little strange, but also the rolling mill. The parts sent by the motorcycle factory are getting more and more strange. In fact, they have never seen them before. For example, the drive wheel of the track is also processed after forging, and it is still not there. Large casting machines, or insufficient casting technology.

In fact, it can also be cast, but the materials are different. Liu Hai tries not to come up with too many material technologies that are beyond the times.

Sun Aiguo didn't pay attention to Liu Hai's side at all recently, because Sun Aiguo was working on a big event recently, and the boring machine project had to be completed before this big event came.

As for the people below, those in the equipment department couldn't understand the drawings, so they sent them to the rolling mill when they got the drawings, and then sent them over to the rolling mill. commanded.

So Sun Aiguo didn't know about Liu Hai's weird parts.

All the parts of the excavator are in place, Liu Hai touched his chin, this thing needs to be assembled outdoors, the house on the side of the laboratory is not too big, fortunately this is a 90 excavator, if it is bigger, you need to drive .

Finally, the parts were almost ready, and Liu Hai started to weld the upper arm. The two sides of the upper arm were processed after forging, and Liu Hai went on the horse himself to weld this, for fear that Li Dali and the three of them could not weld well.

After burning for two and a half days, Liu Hai felt that he would never weld again. He did the welding indoors, and Li Dali and the other three also assisted in heating, using a spray gun.

Because of the large-scale independent production of [-]-ton hydraulic presses, Kyoto has begun to use gas tanks, which are gas from the coking plant.

Li Dali and Li Dali didn't know why the section chief did this, but it was right as the section chief ordered.

As for why there were two of them, one of them went to the boring machine production workshop as a technical guide.

The reason why it is indoors is because the temperature outside is too low. At this time, there is no such thing as secondary welding, which is actually not complicated, but Liu Hai now wants to get the excavator out, and then go back to his hometown to have a look.

Once the excavator is built, it will be ready to go before the Chinese New Year this year, and this year’s plan will be completed.

The entire weld is made in one go. There are four welds in total. There are two layers of steel plates above and below the big arm. These two layers of steel plates and the forgings on the left and right sides of the big arm make up four welds.

In old-fashioned excavators, in addition to the forward and backward operating levers, there are seven or eight operating levers, all of which are hydraulically controlled, while modern ones are controlled by wire.

So after getting on the car, you will see two rows of operating levers. Use these operating levers to rotate the excavator left and right, control the boom, forearm, bucket and so on.

In the open air, Liu Hai and Li Dali built a simple shelf, which was mainly used to hang the engine and the equipment of the cab above the excavator's rotating mechanism.
