Wu Song said: "Water in big trucks, pig houses, and factories all need to be fed in wells, and expensive water trucks are also required to irrigate the land. The cost of a water truck you build is several stagnant. Where can ordinary people afford it? I decided to make a simple water truck that can be used in wells, rivers and other places."

"The cost of commonly used keel water trucks can also be reduced, but we need to open our own wooden utensils. I feel that the price will not exceed three jin of money for large-scale production. I have also studied this, why don't I make a simple water truck with you?" said Jia Simin.

Wu Song was about to cultivate an inventor, and immediately said, "Okay, go to the laboratory tonight." The so-called laboratory is a grocery room in Wu Song. Last time Wu Song developed soap from there, he was full of confidence, and the grocery room became a laboratory.

In the evening, most of the team members who had been training for the whole day had rested, and of course there were a few working hard. Who, Li Kui, was wrestling with Luo Ping? These two guys are super perverted, full of energy, and they fought back and for more than half an hour. Both of them made progress in the competition. On weekdays, Wu Song would go over to give some advice, but today Wu Song ignored them. Wu Song, Jia Simin, and Shi Tiehan, who was on duty at night, came to the laboratory.

Wu Song picked up the quill, brushed it, and drew a structure diagram of the hand-pressing well in minutes.

The barrel-shaped wellhead is thick and thin at the top. There is a piston that can move up and down in the middle. A rocker sways up and down to drive the piston. A long tube leads to the water. Someone asked why Wu Song can draw this picture. It's so funny. Wu Song himself is proficient in machinery. Besides, he said that this kind of water press is everywhere, and even if you close your eyes, you will know what's going on.

Jia Simin looked at it for a while and said, "There is a question here that absorbs water through the piston. Where can I get such a tightly sealed pipe? If I spend a lot of money, it will be worse than a water truck. The water truck will produce a lot of water."

"It doesn't matter if the seal is not tight. We can fill this bucket with water before starting to press the water. It doesn't matter if we seal it." Wu Song said.

"How can the piston suck the water out?" Jia Simin didn't understand.

Wu Song said: "I have drawn the picture. If you really don't understand, study the structure of the bellows, which is similar to that."

Wu Song yawned and was about to go to bed.

Jia Simin asked: "Brother, what are you doing?"

"Go to sleep. I'll leave the rest to you and Shi Tiehan. I'll say hello to the ironworks factory. You can arrange for them to produce samples and get things done as soon as possible. I'm waiting to water the ground in spring." After Wu Song said that, he ignored Jia Simin and went to bed.

Jia Simin complained: "Iron Man, have you seen it? This is an oppression on me, I want to resist."

Shi Tiehan said: "I think this is my brother's care for you. The drawings have been drawn and you have asked you to study them. What else can I complain about? I'm on duty until midnight. Let's start making a sample before talking about it."

A piece of thick bamboo was used as the well head, and a raw cowhide was used as a piston. A thin bamboo was used as a water pipe. The two of them tinkered for more than two hours and fixed it in a water basin. The well head was added to pull the piston, which really pumped the water up. But as Jia Simin was worried, the water was pumped up, but the water came back as soon as the piston pressed back.

Jia Simin shook his big head and said, "Iron Man, how can the bellows stop the return wind?"

Shi Tiehan said: "Just use a small piece of wood, go in one direction."

"I'm really a pig's brain." Jia Simin slapped his head and installed an upward one-way valve on the cowhide piston. A one-way valve was installed at the bottom of the well head and the water pipe. This time, the water was successfully pumped, and the water flowed out along the water pipe.

"Oh, it's successful, it's successful." Jia Simin shouted happily.

Shi Tiehan said: "Go to bed early, and then study it carefully. After all, you can take it to the iron factory for a sample."

"Okay, go to bed, I'll record this." Jia Simin took out his pen and ink, carefully drew pictures, and recorded the text materials, and then he went to bed safely.

The iron plant's process is still relatively backward. There is no steel pipe with a diameter of more than ten centimeters. It is not explained that it is coiled out with such a large diameter. It is immediately modeled and cast, leaving a three-centimeter suction pipe interface at the tail, a water outlet pipe interface at the upper part, and a fulcrum of the hand-pressure piston arm. It took nearly a day to build it. The surface of the casting thing and the things is a bit rough, but it is bulky and sturdy. The water pipe is easy to get it, and the pipe is rolled with iron.

Several craftsmen helped and put the well on the wellhead with Jia Simin.

A blacksmith asked, "Can this thing really press up the water?"

Jia Simin said: "Why can't I put such a lot of money on water? Prepare a few big buckets and see me bring water for you."

Although the blacksmiths did not believe it, they still prepared several large buckets according to Jia Simin's arrangement. Jia Simin installed the rocker arms, pistons, and valves, and then someone added water to the well head. Then they shook the rocker arms. After a while, the water flowed out, which was much more convenient than lifting water with a bucket. Moreover, the well mouth was completely closed with hands, and the safety was greatly improved.

The blacksmiths were so happy that they said, "Manager Jia, you must install this hand-pressing well for our iron factory first. You know, the iron factory has a lot of water."

Jia Simin said: "This is just a sample. You need to decide on the finalization. Okay, my task has been completed. You can set the finalization as soon as possible. As for how much you want to produce, you have to ask Baozheng."

Jia Simin went back to report to Wu Song, saying: "The hand-pressing well was done, and samples were cast with iron. The mass-produced products will be decided by Zhang Blacksmith."

"Not bad, good, very efficient. This well is named Simin Well. The bonus is 100 taels of silver to commend your efforts." Wu Song said.

Jia Simin was flattered and said, "That's so sorry, this is a picture drawn by his brother."

"I'm not embarrassed to be embarrassed. If you have nothing to do in the future, you will be rewarded if you have any problems. In addition, you will be rewarded with a big mule for your daily travel."

Jia Simin was just walking around nearby. There was enough mule riding, so he immediately thanked Wu Song and went to work hard.

Not far behind the Wujiazhuang Big Car Shop, a new large tent private school was built, with an area of ​​more than 100 square meters. The seats and benches were brand new, and there was a large blackboard in front. Dozens of children were studying there.

In the corner of the tent, a huge fireplace was burning with a raging fire. The tent was very warm. Yaying was dressed in coarse cloth clothes, but it could not hide the style that a lady from a noble family had.

"Everyone read with me, this is human, human, human. The writing method is very simple." Yaying taught the children to learn to write. After a while, after class, the children were playing in the tent randomly.

Wu Song came in and said, "Teacher Ya, the environment here is simple, but you can still adapt."

Yaying said: "Yaying is a wandering person, so why can't she adapt? Baozheng not only manages my family's life, but also gives me a job with a monthly salary of two yuan. Yaying is very grateful."
Chapter completed!
