idiot exemption activity "Axin, why are you so expressiony, have you

encountered something unpleasant?" Mo Qingyan noticed Chen Xin's face When he

came back from the outside with a very strange expression, he couldn't help

but ask him a question of concern.

"Oh, nothing, a small matter." Although Chen Xin said so, the expression on

his face didn't seem like nothing.

On the contrary, he feels like something embarrassing has been encountered,

like everyone's black history, not wanting to be known, but embarrassing.

Mo Qingyan probably understood Chen Xin's expression, and when he said that,

she didn't continue to question.

On the other hand, Chen Xin's father noticed that his son's expression was not

normal, and he asked with concern, "Is it a work matter? Isn't it because you

have something wrong with your work?"

"No, a little thing, I can handle it myself." Chen Xin looked indifferent at

this time, as if it was really just a little thing and it was not worth

mentioning.

Seeing him like this, the father who knew his temper didn’t say much, but told

him: “Don’t be afraid of troubles when you have problems at work. Face them

positively. Now that things have happened, you have to think about it first.

Ways to solve them, instead of thinking about how to evade responsibility."

"I know Dad." Chen Xin nodded, the expression on his face changed a bit, as if

he had let go of the burden.

———————

After eating and returning to his room, Chen Xin sat at the desk with a wry

smile.

In fact, both Mo Qingyan and her father had guessed what happened to him, but

they didn't say anything to take care of his face.

But the matter is really not serious, but there was a small accident, which is

similar to having an embarrassment, and it is not really a mistake in work.

In fact, the problem lies with the mining Titan previously designed by Chen

Xin. He just blindly wanted to use the existing prototype, but ignored the

huge difference between open-pit mines and underground mines.

Underground mine mining mainly involves digging tunnels and then crushing

rocks to obtain ore.

In this kind of mining process, before the disaster, because of the

development of science and technology and the improvement of the degree of

mechanization, a large number of machinery was also used for mining

operations.

Manual use of pneumatic picks to break rocks was actually a relatively rare

situation before the disaster. Only some relatively small mines could not

afford large-scale machinery, so they chose more primitive mining methods.

But after the century, there are actually fewer and fewer such small mines.

After the disaster, it is mainly affected by factors such as weather and

environment. Many machines cannot work in a low temperature environment of

tens of degrees below zero, because they were not designed to work in this

environment, which led to many machines. Can no longer be used.

Coupled with the damage to the country's industrial strength, the inability to

mass-produce machinery that can be used in today's environment in a short

period of time has led to many mines still using relatively primitive

artificial mining methods.

When the previous researcher designed the mining Titan, it was for this reason

that the Titan was equipped with a pneumatic pick, and it was finally

simplified to an exoskeleton with a pneumatic pick to balance the structure of

the mine bucket with supporting feet.

However, this is not the case for open-pit mines.

For open-pit mines, they used the method of digging the mountain directly, and

then crushing the ore that was excavated for mining.

The rapid development of science and technology has long turned the past

blasting hills into direct excavation. No matter how hard the rock is, it

can't stop the strong cutting brought by the cemented carbide picks and

hydraulic assistance.

This is of course much more practical and efficient than the air hammer

conceived by Chen Xin.

Although the open-pit mine is indeed unable to operate due to environmental

factors, it does not mean that the digging head is replaced with an air

hammer, and the ore is brute force.

After all, the ore does need to be crushed, but it is not said to be crushed.

And this is exactly where Chen Xin was embarrassed. He sent the mining

machinery he designed to the relevant mining department. People probably

didn’t know how to respond. In order to avoid hurting his face, he sent some

mining machinery information. To him, what is said is for reference.

And when Chen Xin looked at these materials, he immediately understood what

went wrong with him, and what he made was too much for granted.

But fortunately, this is just a design draft, and it has not really been

determined to cause such a thing, so it is nothing more than embarrassment and

timely revision and adjustment.

The biggest problem is that Chen Xin himself made a joke. Fortunately, no one

would laugh at him for this kind of thing.

The mining department is also very interested in his new design and actively

provides information on various mining equipment in order to enable him to

design open-pit mining equipment that can be used.

After referring to the information sent by the mining department, Chen Xin

also had new ideas and planned to overthrow the original design and start

over.

Replace the air hammer with a digging head, and place a large roller-like

digging head directly in front of the machine body to dig and crush the ore

directly, and then send it to the ore bucket behind the machine body. In this

way, the structure can be more simple.

At least the mechanical shovel used to assist in the collection of ore can be

removed. You only need to design a conveyor belt inside the body, and pour the

ore dug up by the excavator directly on the conveyor belt, and the ore can be

directly sent to the ore bucket with the conveyor belt. Up.

In fact, the original mining machinery is designed like this. A machine is

complicated to dig. After being crushed, the mined ore is directly transported

away by a conveyor belt or a large truck. The efficiency is quite high.

It's just that the original large-scale mining machinery really cannot

withstand the current environment, and most of them will be frozen and

difficult to operate.

Thinking of this, Chen Xin felt that maybe he might as well go directly to

transform the original mining machinery instead of hard-working the mining

Titans here.

It's just that since things are done, there is no reason to give up halfway,

he still decides to finish his work.

And this design is not completely problematic, as long as the unreasonable

part is modified, it can still be used.

Chen Xin thought of this, so he rekindled his spirits, turned on the computer,

and recalled the information previously sent to him by the mining department.

He planned to study it carefully before determining how to modify his design.

But while Chen Xin was working, his door was pushed open, and Qin Lan walked

in with a supper.

But she didn't interrupt Chen Xin's work, just put the things aside, and then

retired.
