Scholars in the courtyard.

Chapter 476 I Have Confidence
When everyone came to the brigade headquarters, Mr. Xia and Mr. Tao put aside their concerns, walked aside, and then asked the other party's purpose for coming this time.

After some exchanges, the two knew each other's intentions.

Knowing that it wasn't because of Yang Xiaotao, Mr. Xia was obviously relieved.

Knowing that it was for the steam engine, Lao Tao also laughed.

Afterwards, the two of them understood and smiled at the same time.

They even got together and whispered.

"Old Tao, what's the matter? If this thing is produced, your Ministry of Agriculture will also benefit."

"Let's just talk about the current form and the ones that have been produced. You know more than I do. If there is such a coal-fired tractor, it will be very useful."

"More importantly, steam engines, as long as we have a thorough understanding of the technology, we can mass-produce them. Don't look at the winks from the outside, just rely on the imports."

Mr. Xia said excitedly, the guy in front of him is the head of the Ministry of Agriculture, if he can get his help, then the matter will be more secure.

After Tao Lao heard it, he was not in a hurry to speak, he was also thinking silently in his heart.

Agricultural issues are about stability.

It is their greatest responsibility to fill the stomachs of the Chinese people.

But feeding this populous country is not just about sitting in the office and making a decision.

The current agricultural form, after the toss of big pots of rice, many places have been poor.

How many farmers don't have enough food for themselves, and the food they save is handed over to the state and to the workers.

He felt sour when he heard it.

But he can't help it. After so many years, it's only getting better.

This is why he particularly values ​​high-yield corn.

If it is possible to strengthen agricultural construction, he agrees a hundred times.

But asking him to make a decision now is really a bit rash.

In his position, any decision needs to be cautious.

"Old Xia, this is not something that can be done with just a few words, are you confident?"

"It's not that I look down on rolling mills. This tractor factory either has a solid foundation, or has accumulated experience and invested a lot of money. That's why it was built."

"What about you? No plan, no preparation, no experience, just relying on enthusiasm and impulse, thinking that a group of fitters can rub it out?"

"Old Xia, do you think this is reliable?"

Tao Lao said bluntly, Xia Lao was not angry either.

"It depends on human effort. Besides, we are not unprepared."

"Just like this well drilling machine, isn't it also made from scratch?"

"Since this can be done, why can't a tractor work with a steam engine?"

"The most difficult thing has been done, so what are you afraid of?"

"And, my soldier, I have confidence."

Saying that, Xia Lao stood up, and Tao Lao stood up after listening to silence for a moment.

"Then let's see it with our own eyes, before it's too late!"

While the few people were talking, the sound of cars came from outside the village again, someone ran to the brigade headquarters, Yang Dazhuang hurriedly took people out to check.

Then it was known that it was the car of the rolling mill and the cement factory.

When Liu Huaimin and Li Zhixing came to the brigade headquarters, they were more nervous than excited when they met Mr. Tao and Mr. Xia.

Seeing that the cement pipes were in place, Yang Xiaotao discussed with Yang Dazhuang and sent the cement pipes up.

It happened to let the two chiefs inspect the well drilling machine and the water pressure machine.

After discussing, Yang Dazhuang went to report the situation, and then let the car go to the north slope, and Mr. Yang also brought everyone to the north slope
When everyone came to the north slope, Zhou Kui was leading the people to the new well digging place.

The place just now has been laid, because there are no cement pipes, so we can only go to the next place to try.

The villagers who followed to dig the wells smiled, and they finished two wells in one morning. At this rate, there will soon be enough wells on the north slope for them to water the fields.

It was supposed to go back to eat at noon, but news came from the village that a leader came to inspect and asked them to demonstrate on-site later.

Zhou Kui and others looked at the two old men who came, and after knowing that they were the leaders, they were a little nervous.

Yang Xiaotao went to help in person, and everyone fell silent.

Tao Lao looked at the drilling machine, the drill bit was still covered with soil.

Mr. Xia stared at the steam engine on the ground row car, while Liu Huaimin and Yang Youning were explaining, Mr. Xia kept nodding.

"Old Tao, let's try."

Gao Yufeng asked, Elder Tao nodded and stepped aside.

Yang Xiaotao understood, and then Zhou Kui began to operate, while Wang Jun watched the pressure of the steam engine and added coal at any time.

The drill bit drilled rapidly on the ground, and a cloud of mud splashed around.

Zhou Kui was a little nervous, and the drill went down a little fast.

There were noises all around, and several people were staring at each other without speaking.

In the brigade headquarters, Ran Qiuye was busy with the women in the village. They folded the rolled dough cakes one by one. Some women had already cut them into noodles one by one with a kitchen knife. Because the gray noodles were kneaded hard, they immediately Shrink and distance yourself from each other.

After one sheet is cut, the woman squeezes a handful of flour with her hands, sprinkles it on it, and then shakes it again. The noodles are scattered, shaken in mid-air, and then placed on the grate aside.

Ran Qiuye was cutting potatoes, while Yang Dazhuang's family was cutting pig skins.

Several women were talking about today's events together. They were well-informed, and they all knew that the people who came this time were not simple, and they also knew who they were coming for.

"Teacher Ran, your man is really powerful."

A woman was wielding a kitchen knife quickly, looking at Ran Qiuye with envy and joy on her face.

"Mom Hongye, that's not just Teacher Ran's man, but a young man from our village."

The woman on the other side who was boiling the fire smiled and even teased Ran Qiuye, "There is such a handsome young man in our Yangjiazhuang, who was kidnapped by you. You have to make up for us."

"Hahaha"

Ran Qiuye smiled, "Third Aunt, how are you going to make up for this?"

The third aunt laughed happily, "No need for anything else, when your kid comes out and grows up, he can just marry my Erni."

"It's called not letting the fat water flow into other people's fields, and we have solved it in our own village."

After saying this, the other women around were not happy, "Her third aunt, your abacus is making a lot of noise, and you are starting to focus on it."

"That's right, Teacher Ran, please don't agree."

"Isn't that right? Third Aunt just thinks too much."

Several women attacked together, and the third aunt couldn't stand it any longer, "I said what are you in a hurry for, but I just said, look at you, it's like eating me."

"Don't think I don't know what you're playing for."

"If you ask me, Teacher Ran can still give birth. If you go to the back row, you will always be able to catch a wealthy son-in-law."

After hearing this, everyone laughed again. This said that the third aunt was right, and that made Teacher Ran hurry up to have two more children, which made Ran Qiuye's ears turn red.

These old women dare to say anything.

It's just that she didn't refute what they said, and she also wanted to have more children, so as to spread the branches and leaves for Yang Xiaotao.

"There's water out."

As Yang Youning's excited voice sounded, several people around came together to check regardless of the choking dust.

The leader got closer and stretched out his hand to squeeze the mud, "How many meters is this?"

"Eight meters."

Liu Huaimin reported the number accurately, and he started to memorize it when adding the pipe just now.

"for how long?"

"32 minutes in total."

This time it was Gao Yufeng who answered.

Elder Xia and Elder Tao leaned over, looked at it for a while, and nodded.

Yang Xiaotao asked Zhou Kui to continue, select the right position for the drill, and start working again.

Xia Lao and his superiors came to the front of the car and looked at the steam engine again.

"Is this a pressure gauge?"

The leader asked, Wang Jun, who was operating at the side, was so nervous that he couldn't speak. Yang Youning wanted to go up to explain, but Liu Huaimin stopped him and asked Yang Xiaotao to go up.

Yang Youning understood and quickly winked.

Seeing this, Yang Xiaotao is not humble either. He designed this thing, so it is not stressful to talk about it.

"Chief, leader. This is the pressure gauge, which mainly indicates the pressure inside."

Walked to the pressure gauge and explained, "This pointer returns to zero when it is not working, and the working pressure is generally in the middle."

"This red line represents the limit value. Exceeding this limit value means that the risk increases and you need to be careful."

The two looked at each other and nodded, Xia Lao smiled, "I didn't expect a pressure gauge to reflect so many problems. Is this what you designed?"

"No, this pressure gauge was found in the rolling mill, borrow it."

Yang Xiaotao said seriously.

"Well, as long as it can be used."

The superior leader nodded and said, "Comrade Yang Xiaotao, do you know the maximum horsepower of this steam engine?"

"This, I don't know."

"Then how big do you think it will be?"

Yang Xiaotao looked at Liu Huaimin, they should know, but no one told him, could there be some problem?
Immediately, he said the answer he had calculated in his mind, "It should have fifteen horsepower."

Hearing this, Mr. Xia laughed with his superiors.

Xia Lao walked aside, found a piece of grass and sat down.

Several people from the rolling mill gathered around, and Elder Tao also led people over from the other side.

After a while, everyone formed a circle.

Yang Xiaotao was pushed to the front by Yang Youning and sat in front of Mr. Xia.

"You don't know, the horsepower of this steam engine has reached [-], it's a surprise."

"thirty?"

Yang Xiaotao was taken aback, then looked at Yang Youning who was on the side, seeing him nodding, and only then did he know why Mr. Xia and Mr. Tao came back.

If it is a simple well drilling machine, at most it will play a role in agriculture.

But a powerful steam engine can do a lot.

"Well, our designer is also unexpected."

Tao Lao laughed, and the people around him smiled knowingly.

Yang Xiaotao picked up a small stone on the ground and squeezed it, "This is indeed a little unexpected. However, it is also expected."

"Oh? Tell me, how was it expected?"

Old Xia was interested, and Yang Xiaotao nodded immediately.

I drew on the ground with stones casually, and after a while the general structure of the steam engine was drawn.

"The principle of the steam engine is very simple, as long as anyone with educational experience will understand something.

"We know there are cylinders, pistons, etc., but how to combine them to reciprocate? How to combine connecting rods, valves, pipes...to make them work?"

"What kind of cylinder should be made, the size of the volume, and the size of the cross-section of the piston, these are all to be calculated."

"If you don't calculate and understand the efficiency of steam expansion, you can't make the most suitable steam engine, and you can't exert the maximum power of the steam engine."

Yang Xiaotao pointed to the structure on the ground and said, everyone beside him was attracted by Yang Xiaotao no matter whether they understood it or not.

After Yang Xiaotao finished speaking, Liu Huaimin, who had a little understanding, understood the meaning, "You mean, your design can maximize the efficiency of the steam engine, so it can reach [-] horsepower?"

Yang Xiaotao nodded, then shook his head.

"Secretary, this steam engine can reach [-] horsepower, which is indeed related to precise calculations, but the steam engine I designed is not optimal."

Several people were surprised, they are so much better than other steam engines, and they are still the best?
How much horsepower can the best steam engine get.

However, Yang Xiaotao knew that when he designed the steam engine, the evaluation given by the system to the design drawing was only good-upper, and did not reach the level of excellence.

"There are many factors that determine the quality of a steam engine. The design, materials, processing of parts, fuel used, maintenance of the machine, and the use of other safety components will all affect the efficiency of the steam engine."

After listening to Mr. Xia, he glanced at Mr. Tao. Both of them could see that Yang Xiaotao had a lot of research on this aspect.
