The first legitimate son of the Tang Dynasty

Chapter 260
A high-rotating drum truck is a tool that uses water flow as power to draw water for irrigation.

There is a wheel on the upper and lower wheels. The lower wheel is half submerged in the water. There is a wheel belt between the two wheels. There are many foot-long bamboo tubes on the wheel belt.

When the running water hits the water wheel below, the bamboo tube is filled with water, and the river water is brought to a higher place from bottom to top and poured out.

Drill two hard stakes next to the bank where the current is very fast, make a large wheel, and place the axle of the big wheel on the forks of the piles.

The upper half of the wheel is higher than the embankment, and the lower half is immersed in the water and can rotate freely.Bamboo tubes are attached diagonally to the water-receiving plate outside the spokes of the large wheel. There is a water tank on the bank near the water tube on the wheel.

When the water plate of the big wheel is impacted by the rapids, the wheel rotates, and the water barrel is filled with water. When it turns over the top of the wheel, the mouth of the barrel tilts downward, and the water just pours into the sink and flows along the sink to the field.

The invention date of the high-drum car can be inferred from the literature review in the Tang Dynasty.Liu Yuxi's "Ji Ji Ji" and Chen Tingzhang's "Water Wheel Fu" both vividly describe the function of the high-drum cart.

However, it was not the early period of the Tang Dynasty, but the late period. The successful development of this high-rotating drum truck greatly promoted agriculture. One such high-rotating drum truck could irrigate approximately [-] acres of farmland a day. , the waterwheel saves labor, effort and money. It can be regarded as the most advanced irrigation tool in ancient times.

You have to choose the people yourself, and you don’t know when it will be available.

While Li An was talking to Liu Xiatian, Li An's tool man Li Zhi came bounding over from a distance. Horseshoes and curved shaft plows were all delivered to Li Shimin by Li An through Li Zhi, and it was the same this time.

Li An would not present this high-roller cart himself, he would ask Li Zhi to present it.

At this time, Li Zhi obeyed Li An's words.

After all, Li An has given Li Zhi too many benefits. Li Zhi is now living very comfortably. He has moved out of the palace and opened his own mansion. The monthly expenses of his mansion are basically around [-] yuan.

Li Zhi has some small hobbies, such as shooting and hunting. In fact, Li Zhi does not like and is not good at riding and shooting as some marketing accounts self-righteously describe. In fact, it is quite the opposite. Li Zhi not only likes riding and shooting very much, but also used to do it because he often Qishe was repeatedly admonished by the ministers of the DPRK and China.

More importantly, Li Zhi was very good at riding and shooting. During a hunting trip in the first year of Longshuo, Li Zhi shot dozens of deer and rabbits alone.

The reason why Li Zhi's riding and shooting ability is so powerful is because Li Shimin took him hunting since he was a child.

According to existing historical records, it can be seen that Li Shimin not only raised Li Zhi personally, but also often took Li Zhi to the palace and hunting grounds for hunting. Therefore, Li Zhi also inherited his father's hobby of riding and shooting, and he can be said to be a good riding and shooting person. Good hands.

But hunting is not a simple matter. You need to have your own paddock so that you can hunt freely. How many princes have been criticized by Li Shimin for hunting privately.

However, Li Zhi now has his own paddock. This paddock originally belonged to a noble family. Later, when the noble family wanted to sell it, Li An directly exchanged it with ten glass objects and gave it to Li Zhi.

Li Zhi also likes music, so Li An got some music scores for Li Zhi in modern times. Li An's kindness to Li Zhi is also the reason why Li Zhi is willing to follow Li An's advice.

"Brother!"

Li Zhi came to Li An and shouted happily.

"What have you been doing recently?" Li An asked looking at the happy Li Zhi. "I didn't do anything. I just wrote the music score you gave me in my mansion. Si Zi was also there. We two wrote it together. It was very interesting!" Li Zhi replied.

Li An then smiled and nodded.

He was very afraid that Li Zhi would become a bad prince because of his indulgence. Now it seems that Li Zhi did not go too far, but did his duty. This is also because Li Zhi's nature is actually very kind.

"I will give you something. You must immediately go to the palace to see the Holy Spirit and offer the thing to me."

"What?" Li Zhi asked.

"High-roller truck...!" Li An pointed to the land under his feet and said: "It has not rained for a month or two. Now is the time when the land needs water the most. If it doesn't rain again, the crops on the land will die. Water supply is urgent at this time.

But all the surrounding creeks and rivers have dried up, so we can only fetch water from the big river outside, but the water level has dropped too much, and the river is too far away from our fields.

In this way, we need to dig ditches and use high-drum trucks to divert water. No matter how low the water level is, this high-drum truck can pump up the water. It can irrigate more than 700 acres of fields in one day. As long as we have it, we can Easily cope with the situation without water. "

"Brother!" Li Zhi raised his head and looked at Li An and asked: "Such a good thing, like horseshoes and plows. There are also alcohol, suture therapy, and catgut. They are all beneficial to the country and the people.

Why are you unwilling to contribute yourself? "

Li An looked at Li Zhi and smiled slightly, then heard Li Zhi continue: "I actually heard some rumors in the market that you and my father looked very similar when they were young."

"Who said that?" Li An looked at Li Zhi.

"Don't worry about who said it. I just feel that these words are not groundless, and you and I are indeed somewhat similar. They say that you are a child abandoned by the royal family. You hate your father and the queen, so you would rather stay here Lijiacun has no reason to admit his identity."

Li An smiled slightly again: "If I really hated anyone, then I wouldn't stay in Lijia Village now. And you have also seen that Li Duoduo has to go to the palace to play with the Queen every once in a while. .

There are some things that I don’t want to talk too much about, and you don’t have to worry about them anymore. Just remember that I just want to stay in Lijiacun. For other things, don’t listen to me, and don’t care about it.

I'm your big brother, always will be, just remember that. "

After Li Zhi listened, he nodded slightly. After that, Li An took Li Zhi back to the village, and then gave Li Zhi the design drawings of the high-rotating drum car. Li Zhi did not waste any more time and was the first to do so. Time returned to the palace.

After Li Shimin got the design drawings of the high-rotating drum truck and Li An's advice on building ditches to deal with water shortages, he called Fang Xuanling and Changsun Wuji to Ganlu Hall overnight. The three of them discussed for nearly two hours. Two days later, an order was issued to the Guanzhong area to build ditches immediately without any mistakes.

Then he told the story about the high-rotating cart and promised that a village would be given a high-rotating cart for free by the court.

Li Shimin originally thought that after saying this, there would be less fighting for water, but no one thought that the people's eyesight was very shallow. They saw that it was not raining, so they were worried and wanted to grab water. , for this reason, the fight still occurred, and Li Shimin had no choice but to recruit Li An into the palace.
