Hanjiazhuang, farmland outside the village.
Lao Hu kept thanking the young master a lot, but he was clumsy and always said the same words. Li Zexuan was very embarrassed when he heard this. Han Li interrupted him and said, "Lao Hu, you are here After waiting for so long, haven’t you got the cattle yet?”
Hearing this, Lao Hu shook his head despondently, pointed to a middle-aged man who was plowing the land not far in front and said, "Li Zheng, look, Lao Wang's family hasn't finished using it yet. There has been little rain this year, and the field has always been difficult to plow. This worries me to death."
"Uncle Han, can't you go to the county to borrow more cattle?"
Li Zexuan felt a little confused when he heard Lao Hu's complaint, so he asked.
Han Li shook his head in embarrassment: "Master, you don't know something. We have a large number of people in Zhuangzi, and the county has allocated more cattle than other Zhuangzi. At this time, spring plowing is being carried out everywhere, and there must be no extra cattle in the county. Give it to us.”
Lao Hu also sighed heavily at this time: "Hey, Li Zheng, at the current pace of plowing, I estimate that many farmers in our village will miss the spring plowing period. How can we deal with this?"
Li Zexuan was also shocked when he heard this. He was also a child in the countryside in his previous life. He knew how serious the consequences would be if he missed the spring plowing period. It is estimated that many families will go hungry by then. What's more, if everyone misses the spring plowing period, their enthusiasm for raising chickens will definitely be affected. This The problem must be solved.
He pondered for a long time, looked at Old Hu next to him, and asked: "Uncle Hu, how much land can a cow plow in a day now?"
Old Hu scratched his head, thought for a while and said: "Master, it is difficult to plow the land this year. A cow can plow up to four acres of land a day. If you plow more, I am afraid that the cow will be exhausted, which is not worth the gain. If this is done, In previous years, six or seven acres of land could be plowed in one day. Alas, it’s all because of the lack of rain this year.”
There are only four acres of land in one day, which is too slow. Li Zexuan frowned, looked at Han Lizheng, and asked, "Uncle Han, how many cattle are there in the village now?"
"Master, Zhuangzi has rented twenty cattle this year, which is much more than other Zhuangzi."
Li Zexuan made a mental calculation. At this rate, wouldn't it take more than a month to finish the plowing? This is not okay. It's not that he hasn't thought about spending money to buy cattle elsewhere, but in this era, cattle are always nervous. If he buys cattle from another place, what will the people in that place do? It would be great if I could be like other time-traveling protagonists and bring a system with me. I could directly exchange it for a farming tractor, which would ensure that I could plow dozens of acres of land in a day.
Alas, since there are no tractors and it is difficult to increase the number of cattle, it seems that now we have to find other ways to improve the current efficiency of farming. This problem is easy to solve. He has countless advanced mechanical models in his mind, and he will definitely be able to find many plows that are more useful than the current one.
"Uncle Han, let me see what kind of plows the farmers use."
Li Zexuan confessed and walked towards Lao Wang where Lao Hu pointed out before. Han Lizheng and Lao Hu also quickly followed.
Li Zexuan came to the field ridge next to Lao Wang and began to look at the plow used by Lao Wang. Lao Wang was concentrating on plowing the land, and he didn't realize that someone was watching him next to him.
Li Zexuan was highly short-sighted in his previous life. In this life, I don't know if it was because of his magical power, but his eyesight was very good, and he could clearly see the structure of the plow from a long distance. He found that the structure of this plow was really strange. The shaft was straight and about nine feet long. With such a long shaft, it would be difficult to turn around.
Li Zexuan quickly built the three-dimensional structure of the plow in front of him in his mind, and based on the engineering mechanics knowledge he had learned before, he conducted a force analysis on each part of the plow and found that the plow needed to exert a large pulling force to actually plow the ground. , this structure is obviously unreasonable.
Li Zexuan frowned. He was thinking about which better plow should be used to replace the current plow. Various plows from different eras flashed through my mind, and suddenly I stopped at a plow that was not particularly different from the current plow.
"It's you!"
"This should be called a curved shaft plow. It probably hasn't appeared yet. The structure of this curved shaft plow should be improved from the structure of the plow in front of you. Although the changes are not too big, every change is very critical. Compared with the plow used by Lao Wang in front of me, this curved shaft plow is obviously more labor-saving, which can be easily seen by drawing a force analysis diagram."
At this time, Li Zexuan not only has the three-dimensional model of the Quyuan plow in his mind, but also its force analysis diagram. It can be clearly seen that the Quyuan plow is more labor-saving, and not just a little bit. The most important thing is that this plow is not difficult to make and can be easily manufactured in large quantities. When he returns, he can find craftsmen to start manufacturing immediately, so as to ensure that the farmers in Hanjiazhuang will not miss spring plowing.
In fact, the Tang Dynasty currently uses long straight shaft plows passed down from the Han Dynasty. The curved shaft plow conceived in Li Zexuan's mind only began to appear in the Jiangdong area in the late Tang Dynasty, so it is also called Jiangdong plow. Compared with the long straight shaft plow, the curved shaft plow is indeed more flexible and labor-saving. When the soil is relatively moist, a strong young man can pull it.
"Uncle Han, just plow like this for now. I will think of a way for you in the next two days, so that farmers will never miss the spring plowing." Li Zexuan had a solution in mind, so he turned around and said to Han Lizheng.
Han Lizheng and Lao Hu both looked surprised when they heard this. The land is the life of the farmers. If they miss the spring plowing, the harvest will be greatly reduced, and it is not uncommon for people to starve to death. They didn't expect that the young master would help them find a solution. This was such a surprise.
"Thank you young master. All the farmers in our Hanjiazhuang will remember the young master's kindness forever. But I don't know what method the young master plans to use? Is he going to Chang'an to buy more cattle?" Han Lizheng bowed seriously to express his thanks, but he was also curious about what Li Zexuan would use. The only way to help them is to buy cattle for them, the price would be too high.
Li Zexuan shook his head and said with a smile: "Of course I'm not buying cattle. I bought the cattle. What do farmers in other places use? Uncle Han, in two days I will bring you a more labor-saving plow." , then your plowing speed will be at least doubled!"
Han Lizheng and Lao Hu were both shocked when they heard this. Is there such a plow in the world
Lao Hu's eyes widened in an exaggerated way, and he shouted in disbelief: "Young... Young Master, you... are you telling the truth? How can there be such a magical plow in this world?"
Li Zexuan nodded with certainty and said: "Uncle Hu, don't worry, seeing is believing, we will naturally find out in two days!"
