The more Xie Kai spoke, the more excited he became.

The magic change of 59 tanks is the most in the whole world.

Xie Jianguo listened very carefully at first, picked up the pen from time to time, and recorded it in the work notebook he carried with him, which made Xie Kai even more excited.

This made Xie Kai, who had never been affirmed by his father, not excited.

As soon as he said it, he couldn't hold it back, and Xie Jianguo was dumbfounded when he heard it.

“...... Based on the chassis of the 59 tank, it was possible to develop a self-propelled gun, changed to a double 37 anti-aircraft gun, a double 57 anti-aircraft gun ......"

"Ahem, Xie Kai, what about the fire control system......" Seeing his son spitting everywhere, Xie Jianguo had to interrupt his conjecture.

"Uh...... Dad, we're talking about the fire control system. ”

"The various modifications you mentioned based on the technology of the 59 tank have nothing to do with fire control, right?" Xie Jianguo was a little skeptical that his son was smart or stupid.

Xie Kai shook his head, "Dad, it has a lot to do with it." In addition to the 627 factory and the 541 tank base in Zhongtiao Mountain, we also have a full set of 59 tank production technology and production capacity! Have you forgotten?"

The role of this base is not only research, but also an important function is combat readiness!

After the Sino-Soviet relations became bad, the country began to build the third-line project, the 404 base, which was originally the backup of the 404 nuclear plant in Yumen in the north, after all, the Soviets helped build it and understood the situation.

The relationship between the two families is not good, and the big brother of the Soviet Union still wants to bully people, and it is too far to transport equipment from other places in this great northwest. Moreover, the entire north is their area of attack.

Later, as soon as the chiefs summed it up, they had to say, anyway, a sheep was a drive, a group of sheep was also a drive, Qilian Mountain was so big, it was still in the desert, and it was not easy to find it when the Soviets invaded, so they simply made it bigger.

The Soviet Union really invaded, and heavy weapons and equipment could be produced in the Great Northwest......

If it were not for the production of tanks in wartime, the scale of the Hongqi Mechanical Plant would not have been so large.

Xie Jianguo was dumbfounded by his son's whimsical thoughts.

"I said you won't be sleepy? can't you discuss it tomorrow? Don't look at what time it is, and then the wake-up call will have to be sounded later......" Liu Xu went to bed early, got up and drank water at this time, and saw that the father and son were still discussing.

"You go to sleep first. Xie Jianguo said to Liu Xu, and then asked Xie Kai, "Let's talk about using a tank chassis to make an excavator first." We have more than 200 chassis in stock, so don't say it for the sake of showing off. ”

The son said that the matter of the fire control system was too far, and Xie Jianguo felt that it was better to deal with the matter in front of him first.

"What is there to show off, most people know, just hide in the hole under the sand date grove on the west side of the base...... Xie Kai pouted.

After all, a tank chassis is not a weapon, and ordinary people don't know what to do.

No one can move it, and they are not afraid of being stolen.

None of the guards troops.

When Sino-Soviet relations were at their most tense, a batch of chassis was transported every three or five days and stored in the underground warehouse, where they could be assembled as long as they underwent some fine processing, and there were also reserves in the tank artillery base.

As long as China and the Soviet Union went to war, the base would soon be able to assemble hundreds of tanks to support the front line.

Xie Kai: When they were young, they used to run there to play.

Xie Jianguo was even more surprised, he thought it was very secretive.

"Actually, I just knew that there was something in the base, so I said I could build an excavator. Excavators are not as complex as tanks, do not require armor, and do not require tank guns. The tank engine is under the rotating part, remove the upper turret, and the armor is not required, in the original turret part, plus the cockpit and the rotating shovel arm of the excavator are OK......"

The 59 tank was converted into an excavator, and there was a mature plan, and Xie Kai did not need to think about it at all.

Of course, in the face of his father, he definitely can't say that.

It all became his thoughts.

"But the tank chassis is military, which is different from the imported excavators on the market. Xie Jianguo's mind kept coming up with the appearance of dismantling the turret of the 59 tank, and then adding the cockpit and the working cantilever.

How to think, how to feel weird.

What's more, the tank chassis belongs to military materials, and it is not certain whether the military will agree to it, which may involve secrets.

Unlike other excavator chassis, this makes others not necessarily acceptable.

"Dad, you can't think like that. The chassis is for military use, and the production of tanks belongs to the military; is it still for military use when it is used to produce civilian products? For ordinary people, the military industry is the guarantee of quality! Why are people in China willing to use imported excavators with higher prices instead of domestic ones? Quality is not good! Efficiency is not good!" Xie Kai was a little crying and laughing at his father's thoughts.

This is the sadness of being out of the market and not understanding the market.

In the entire base, it is estimated that there is no one who knows about the outside market.

Unlike other state-run units or military-to-civilian units, they can send people to inspect everywhere.

404 is too closed.

Xie Kai knew that no one in the entire base was willing to accept the sequence of leaving the national defense science and technology workers.

This is Dongfeng City!

Dongfeng City, which has created countless miracles.

"What's more, if we get it out, we don't need to sell it to private users at all. Doesn't our military have an engineering unit? Isn't the engineering unit divided into infrastructure, hydropower, and so on? They are engaged in construction, and there is a huge demand for such products!" Xie Kai was prepared to do this from the very beginning, which was to pay attention to the orders of the engineering troops.

"Also, they are the richest troops in our army. Xie Jianguo nodded.

Although these engineering corps can be said to be militarized management, they can also be said to be enterprises.

Financially independent accounting, self-financing.

Since the beginning of reform and opening up, the country has been engaged in infrastructure construction on a large scale, and these contingents can be said to be the richest units in the army.

"Which soldier doesn't want to carry a gun and doesn't want to drive a tank? Although we are only excavators, chassis, load wheels, and engines, they are no different from the 59...... Will the engineers like it?" Xie Kai smirked.

There is money, there is demand, and naturally there is no fear that the engineering troops will not buy it.

Xie Jianguo kept nodding and praised his son's unique vision, which can be regarded as a military product.

He still likes to engage in military products, although they are not used for war.

In this way, the resistance of other comrades will also be reduced. You can't discriminate that the engineering troops are not troops, right?

"In fact, to build an excavator, we need to do the least work, the technical difficulty is less, and we can achieve results quickly. The hardest part is the hydraulics. When I was in Shanghai, I observed the front bucket, which needs to convert the power of the engine into hydraulic pressure and act on the tooth root part of the edge of the bucket...... Dad, you take out a few drawings, it's not easy to explain without pictures......" Xie Kai continued to analyze for Dad.

Let Daddy figure it out, and then you can arrange it for someone else to do it.

The chief engineer is mainly responsible for overall control, technical guidance, etc., and does everything himself, and he has to be busy?

Xie Jianguo took out a few pieces of A3 drawing paper, vacated the coffee table, put it on it, and handed a 2B pencil to Xie Kai.

Xie Kai grabbed the pencil and directly drew the sketches of the excavator's big arm, small arm, and the hydraulic support rod on it, and then drew a bucket and it was over.

It's good to be able to see it.

"This is part of the structure of the excavator work. You see, this is the boom part, the hydraulic support rod is retracted, and the boom hangs down, stretches out, and stands up. This is the ...... where the greatest force is put on the whole working part."

"This is the forearm part, retract it, and pull the forearm outward...... Then stretched out, the forearm was driven by the hydraulic support, and it retracted ......"

"The bucket is driven by a hydraulic support on the forearm, and the digging force is also determined by the hydraulic force. ”

Xie Kai pointed to the various parts of the sketch and kept explaining it to his father.

Xie Jianguo had never seen an excavator, Xie Kai pointed to the picture and told him, and he understood.

"The design of the hydraulic part is really a problem. Xie Jianguo nodded, hoping that his son would tell him how to calculate.

Xie Kai looked at his father's expectant eyes and rolled his eyes directly, "Dad, I don't know how to calculate, otherwise where do you need a technician?"

"By the way, and the operating system. This is different from a tank, you have to add a device to control the shovel arm......" Xie Kai finished and snorted.

When I looked up at the wall clock on the wall, it was five o'clock.

"Dad, I can't bear it, I have to sleep. Don't think about it, organize a meeting tomorrow to discuss, anyway, the structure of the excavator is like this, not complicated. The research of the hydraulic system is also beneficial to the hydraulic and support system of the mining machinery in the future, and even the artillery stabilization system of the tank can be used...... "Xie Kai knows how important the hydraulic system will be in the future.

Penetrate into almost all areas of automation.

The technical strength of Hongqi Machinery Factory is not bad, and if we work hard in this area and accumulate rich experience, the road behind will be broad.

"Don't be in a hurry to sleep, let's talk about the cockpit under this tank, how to deal with the fighting compartment!" Xie Jianguo was a little confused. "If only the engine part is kept, the rotating part above it will not be easy to place. If you don't remove it, it will cause leaks......"

Xie Kai's eyes were about to open.

In the past few days, the cabbage incident, and how he thought about how to make his industry safer, he didn't sleep well at all.

Dad often stays up late and works overtime to get used to it, and he can insist on not sleeping for several days in a row, but he can't.

In addition, the body is still developing, and the need for sleep is higher.

"Dad, how could the engineering troops leak secrets? Besides, the tank chassis is just a chassis, and the wheels on both sides are added to a board, and the excess part is removed. It really doesn't work, put the engine on top of the slewing gear. But then I don't think the engineers will like it...... Of course, the tank gun and turret, more than ten tons, can be driven by the slewing gear......" Xie Kai squinted his eyes and walked towards the room.

When Xie Jianguo heard this, he slapped his head suddenly.

That's true, just install the engine on it.

But after thinking about it, Xie Kai was right, if the engineering troops were not to be installed on it, wouldn't it be in vain?

"Don't worry, ask another question......" He grabbed Xie Kai.
