There are 2,900 or more updates. Brothers, the monthly ticket is 278, and there are 22 more updates!

Twenty soldiers from Zhangjiagou went to war, and more than 30 male men were also recruited by the government to be civilians and transported. The village suddenly lost more than fifty strong men and a lot of fun.

Now Zhang Chao enjoys a cave alone.

The guards of Uncle Zhao and Uncle Wang also went to war. The entourages of the two fathers of the little eight little thirteen didn't need to go to the battlefield, but they were transferred to military officers from other military offices as entourages. Their two-month period this year has not yet ended.

It turned out that six people slept in the same room. Zhang Chao always thought about when he could live alone, but everyone was really leaving. He felt a little missed. At night, after dinner, after dark, he could still call two landlords on the kang table and chat.

The lonely and bored Zhang Chao took out his laptop. After charging with a solar charger last time, he still has some electricity. However, the computer has no internet, so he is still sad.

I was very bored, tied up the door, brought my headphones, watched a movie, and became even more bored after watching it.

After not being able to sleep, Zhang Chao had to take a computer to search for some information. After reading the new and old books of Tang, Zhang Chao felt a little bored. It simply records some major events in the past, and it was a bit far away from Zhang Chao.

He finally found some papers and other materials written by experts on ancient agriculture.

There are already water trucks such as overturned trucks, well trucks, and tube trucks. Zhang Chao’s bathroom is building well trucks and overturned trucks. However, after looking through the information, Zhang Chao did find a kind of agricultural tool that is not available yet, but is extremely advanced.

Quyuan plow, also known as Dongjiang plow.

According to the information, it is said that the Dongjiang area, which was first invented in the late Tang Dynasty, is now a straight shaft and a long shaft. The plow is very heavy, and it is often necessary to plow two oxen to plow the fields.

This new curved plow has several major improvements. First, it is to change the straight and long shafts to curved and short shafts, and install a free-turn plow plate on the shaft head. This not only makes the plow frame smaller and lighter, but also makes it easier to turn and turn, and operate it flexibly, saving manpower and animal power. The new plow only needs a cow.

Zhang Chao couldn't help but slap his legs when he saw it. Why didn't he notice this before?

The Zhang family now has more than a thousand acres of land. If they create this new plow, it will not only greatly help their own tenant farmers, but also sell it as a commodity. If you hire some carpenters to open a farm tool shop to sell plows, you will definitely make money.

If I can't even do it well, if I can contribute to the government, well, I might get a reward.

The information found by Zhang Chao contains detailed records of the curved plow. The curved plow consists of eleven parts, namely the plowshare, the plow wall, the plow bottom, the plow, the plow arrow, the plow shaft, the plow tip, the plow review, the plow construction and the plow plate.

There are also detailed drawings on the information, as well as restoration drawings and production methods.

The plows used by the Tang people now are long straight plows. This kind of plow is not flexible enough when plowing the land, and it is laborious to lift soil, and it is not efficient.

When operating the short curved plow, the plow body can swing, is mobility, can be deeply plowed, and is light and soft, convenient, and is convenient for roving. It is quite suitable for the characteristics of water in paddy fields in the south of the Yangtze River. Therefore, the short curved plow first appeared in Jiangdong in history.

However, the short curved plow is also easy to use in Guanzhong.

The short-curved plow adds plow review and plow arrow. The plow review can make the plow arrow go downward, and the plowshare can penetrate deeper into the soil, which is suitable for deep plowing. If the plow review is mentioned, the plow arrow goes upward, and the plowshare will fall into the soil, which is shallow, which is suitable for shallow tillage. This relaxed and relaxed adjustment is conducive to intensive cultivation.

Moreover, the plow wall can not only break the soil, but also push the plowing soil to one side, reducing the resistance to the plow's advance.

In history, the Quyuanli was quickly promoted as soon as it was published. Until the Song, Yuan, Ming and Qing dynasties, there was no obvious change in the general structure of the classics.

The curved plows in the Song Dynasty only made the plow shaft shorter and more bent, reduced the quotient and pressure bonds and other components, making the plow body structure lighter. During the Ming and Qing Dynasties, the iron shaft began to be made due to the development of iron smelting.

Zhang Chao felt that he could directly take out the very mature short-shaft plow from the Song Dynasty.

A mature short-curved plow is not complicated. After reducing the structure, it is even only twenty or thirty kilograms and can be carried away with one hand.

Except for the plow shovel, the rest of the plow is made of wood, which is not expensive.

In fact, if you want to be lighter, you can also use steel for both the plow shovel and the plow wall, which are lighter. However, iron prices are extremely high nowadays, so except for the plow shovel, the rest are replaced by wood, including the plow wall on the inclined surface.

Even the plow shovel is just the tip in front of it is made of iron and is wrapped around the wood, minimizing the use of iron and reducing costs.

Zhang Chaoyue became more and more excited when he read it. This can make a big news.

Taking out the paper and pen, Zhang Chao copied the mature curved plows of the Song Dynasty from the computer, including patterns, accessories, production methods, etc.

The next day, early in the morning, Zhang Chao got up.

He didn't even practice the first time he shot, so he ran to find Keshan's carpenter uncle.

Carpenter Ke is now bringing his disciples to build a water truck for Zhang Chao's bathroom.

A well truck that lifts water from a well, lifts water from the well and then sends it into a canal.

The water flows into a dug water storage pool, then build a water tower next to the water storage pool, and then set up a barrel truck in the water tank to deliver the water to the water tower.

The water tower is connected to a bamboo tube, which can deliver water to all parts of the bathroom.

Mr. Ke is an old carpenter and can make well trucks and tube trucks.

However, Zhang Chao felt that these carpenters were really good at making well trucks and barrel trucks, and they didn’t even need a nail or glue. They all had mortise and tenon structures, which were quite solid.

Even with just one axe, they can cut a log into square wood, an axe and a plane, and a saw and a chisel. They can create all kinds of things.

Time is just a bit slow.

A well truck and a barrel truck, Mr. Ke had to take his disciples and grandchildren to work for a month.

"Uncle Eight, please help me with something."

Zhang Chao showed the drawings he had drawn to Master Ke Ba to see.

"Is this a plow?" Master Ke Ba took the drawing and saw it immediately.

"This plow is a bit strange. Why is the shaft curved and so short? Many places are different from what they are now."

Zhang Chao smiled, "Uncle Eighth, how do you think of this plow?"

"It's hard to say, where have you seen such a plow? Is it easy to use?" Ke Ba didn't make a conclusion immediately.

"Uncle Eight, this is called a curved plow, which is lighter than a straight plow, and more convenient and easy to use. When plowing the same depth, the curved plow requires only a cow to pull it easily and easily."

"Is it really so useful?" Ke Baye was surprised. If it was really as Zhang Chao said, it would save a cow. A cow can support five strong labor. In the past, when there were no cows, they could only have a plow. Plowing plow is similar to a shovel. Plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing plowing pilling pilling pilling pilling pilling pilling pilling pilling pilling pilling pilling pilling pilling pilling p

"What do these things look like?"

Ke Ba is worthy of being an old carpenter, and he suddenly saw three parts: plow building, plow review and plow arrow.

Zhang Chao told him that these three are components that adjust the depth of the plow. Through these three components, you can easily achieve the effect of thinking deep and thinking shallow.

Master Ke Ba was already listening more and more seriously, his eyes were shining.

Without saying a word, the old man put down what was originally in his hand, and directly took the drawings and gestured for a long time. Then he ran to pick two good woods and came back, picked up the axe and started to peel them.

"Would you like to find a bent wood for this curved shaft?" Zhang Chao asked on the side.

"No, just cut one out." Master Ke Ba couldn't wait.

Master Ke Ba called all his disciples and grandchildren over, and asked them to stop the work of the water truck at hand and make new plows. He divided the tasks and each person did the same.

Zhang Chao sat there and watched, discussing the specific details with Master Ke from time to time.

It took only half a day to do that, Ke Baye and his friends had already made out the various parts of the curved plow.

Looking at the parts that were placed all over the floor and emitting the fragrance of fresh wood, Zhang Chao was also very excited and finally came out.

The final assembly was operated by Master Ke Ba himself, with axe clanging, and in a short while, a curved plow was formed.

A completely wooden short curved plow is completed by putting a plow shovel on the tip of the plow bed.

Master Ke Ba directly broke a plow from his own plow and shoveled it down, and then put it on the new plow.

"It's done!"

Master Ke Ba walked around the plow for a few times, picked up the plow and held it in his hand and tried it. Finally, he held the tip of the plow to try it out.

"Why do you take the lead and try it?"

No matter how good the plow is, if you haven't tried it, you can't know whether it's easy to use.

"Then try."

Master Ke Ba personally carried the plow, and Zhang Chao and others followed behind.

I took the cows from Keba's family and then came to an open land outside the village. This was a land for resuming. After a few years of cultivation, in order to accumulate fertility, I had to fallow for a season.

Put a bend on the cow, tie a plow rope, and put a plow hook on it.

"Start ploughing first."

Ke Ba said excitedly, then adjusted Plum Jian.

"Hi!"

Ke Baye shook the cow rope, and the buffalo began to move his footsteps with the plow on his back. The plow shoveled into the ground. The cow pulled the plow forward, and the soil was shoveled up. When it encountered the inclined plow wall, the soil turned to one side.

There is no need to drive it, the cow can easily carry the plow on his back.

Although Master Ke Ba was a carpenter, he usually farmed. He immediately felt that it was easy to hold the plow and not much effort. This was impossible for the straight plow in the past.

The original long straight plow is at least twice the weight of this plow, and it is difficult to control the plow.

After a plow, Ke Baye immediately adjusted the plow and reviewed the plow construction.

He wants to try to practise deeply now. If practise deeply, it will be useful, then the plow will be perfect.

"Hi!"

Starting again, this time the plow was much deeper, but the buffalo hardly slowed down, and large pieces of soil quickly plowed up and turned to both sides.

“It’s easy to use, it’s really easy to use.”

The Eighth Master had just plowed halfway and started shouting.

After he actually used it, he realized that this plow was so easy to use.

"Is it really useful?" Zhang Chao asked.

"It's very useful than the original plow. With this plow, just one cow is faster than the original two cows to pull the plow. It's not tiring to support the plow, so it's easy!"

Zhang Chao smiled, laughing very happily. He didn't work hard last night. To be continued.
Chapter completed!
