Qiquge Workshop.
"Xiao Xuan, old man, I speak more frankly. Don't be offended. Although your scooter is innovative, in the end it is just a child's plaything and is of no use to people's livelihood. Your roller bearings are of great use. Jiji, since you have talent in this area, study more things that are beneficial to the people."
After Uncle Fu saw a few people sitting down, he began to preach to Li Zexuan with earnest words. Li Zexuan was speechless. This old man was really straight-tempered. If he were a petty person, he would definitely hate him for this.
Fortunately, Li Zexuan is not this kind of person, and he still agrees with Uncle Fu's words.
"What Uncle Fu taught me is that this scooter was just a toy to coax my roommate. Of course I won't just do this in the future."
Uncle Fu nodded happily and said, "Yes, a boy can be taught."
Li Zexuan remembered another purpose of coming to the workshop this time, and said: "Yesterday I went to my village and found that the fields this year are particularly difficult to cultivate due to lack of rain. It is estimated that some farmers will miss the spring plowing. Brother Shaoning and Uncle Fu know About this?"
Yan Shaoning looked solemn and said in a deep voice:
"This situation does not only happen in your Zhuangzi, but also in all the counties around Chang'an. According to my father, this matter has alarmed the imperial court. Your Majesty has also learned about it and is sending people from the north. Several prefectures and counties in the country transferred a group of cattle to Chang'an, and then distributed them to farmers, trying not to let farmers miss spring plowing."
Uncle Fu also nodded and said: "I have heard about this matter, but Xiaoxuan, what is your purpose in bringing this up? We can't help with this kind of thing, we can only rely on the court."
Li Zexuan stood up and disagreed: "Uncle Fu's words are wrong. As the saying goes, if a worker wants to do his job well, he must first sharpen his tools. As a craftsman, you must also have a craftsman's spirit. You just taught the boy to study more about it. Things that are beneficial to people’s livelihood, so why can’t we make more useful farming tools for the people?”
Uncle Fu raised his eyebrows. He had been working hard in this field for so many years, but today he was lectured by this little kid. He was a little unhappy and arrogant. He frowned and said:
"What you are saying is easy. The straight-shaft plow used in the Tang Dynasty originated from the Han Dynasty. After several improvements, it is already the most advanced farming tool. How can there be a better farming tool than this?"
"I don't agree with what Uncle Fu said. How can a craftsman not strive for innovation? How can he do what the predecessors planted trees and the descendants enjoy the shade? How can he know that he can't make better farming tools without trying?"
Uncle Fu was unconvinced and said, "So, you can make better farming tools?"
Li Zexuan also saw that this old man had a stubborn temper. It didn't mean that he was evil-minded, but he just didn't allow others to question him in the field he was best at. Li Zexuan had seen many such people in his previous life, generally in various fields. All big cows have this bad habit.
At that moment, Li Zexuan didn't waste any time. He took out the drawing of the Quyuan plow that he had already drawn from his sleeve, spread it out on the table, and said to the two of them:
"This is a more labor-saving plow that I accidentally came up with yesterday when I saw farmers using straight-hook plows in Hanjiazhuang. Today I am trying to find a workshop to make a batch as soon as possible. Brother Shaoning, Uncle Fu, come and take a look. .”
Yan Shaoning and Uncle Fu couldn't wait to come over and look at the drawing. It was the first time that Uncle Fu saw this kind of drawing technique. He couldn't help but frowned. He wanted to ask Li Zexuan, but he was a little embarrassed to ask. He had just argued with Li Zexuan and was really embarrassed.
Yan Shaoning was very familiar with this painting method. He read the drawings carefully, then closed his eyes and meditated, imagining the structure of this plow in his mind. Within a few breaths, he opened his eyes.
"Xiaoxuan, your plow should have evolved from a straight-shaft plow, right? I saw that you made changes to the length and shape of the plow shaft, and also installed a wheel disc on the shaft head. This structure I think But I’ve never seen one, and I can’t say which one is more labor-saving, your plow or the straight-shaft plow we use.”
At this time, Uncle Fu saw that Yan Shaoning was speaking eloquently. It was obvious that he could understand this kind of drawings. Uncle Fu couldn't help but feel depressed. He had been a craftsman all his life, and he also had his own pride in this field. Unexpectedly, today, it seemed that Not as good as these two little dolls.
In fact, after Yan Shaoning finished speaking, he noticed that Uncle Fu was still staring at the drawings. After thinking about it for a while, he understood what was going on. He patted his head and said sheepishly:
"Um, Uncle Fu, I forgot to tell you that this drawing method was created by Xiaoxuan. These three pictures represent the shape of the object when viewed from three directions..."
Yan Shaoning began to spread the knowledge of three views to Uncle Forbes again. Fu Bo has been studying this field for so many years, and he can understand it all with just a little bit of digging. Even though he did not agree with Li Zexuan's views before, now he also somewhat agrees with Li Zexuan's drawing method.
He nodded and looked at the picture again.
Li Zexuan also explained at this time: "Uncle Fu, brother Shaoning, I call this kind of plow a curved shaft plow. It consists of eleven parts, namely the plowshare, the plowwall, the plow bottom, the pressing trowel, and the plow. The forehead, the plow arrow, the plow shaft, the plow comment, the plow construction, the plow tip, the plow pan.”
Li Zexuan pointed at the drawings and explained them one by one as he spoke. The two of them listened to him attentively. Even though they could understand the drawings, they would definitely not be able to catch up with Li Zexuan in terms of their understanding of Qu Yuanli.
Li Zexuan continued: "I changed the long straight shaft into a short curved shaft, and installed a freely rotating plow disc on the shaft head. This not only makes the plow frame smaller and lighter, but also facilitates U-turns and turns, and is flexible in operation. Save more manpower and animal power.”
"In addition, I also added a plow and plow arrows. If you use a push plow, you can make the plow arrows downward and the plowshare will penetrate deeper into the soil. If you lift the plow and make the plow arrows upward, the plowshare will penetrate into the soil slightly shallower. The combination of plow review, plow arrow and plow arrow can adapt to the different requirements of deep plowing and sign plowing.”
"The plow wall can not only break up the soil, but also push the plowed soil to one side, reducing the resistance of the plow. Combining these improvements, the curved shaft plow is at least 50% less labor-intensive than the straight shaft plow."
Li Zexuan talked eloquently over the drawings. The two of them nodded frequently while listening. Finally, Uncle Fu couldn't help but said:
"Your design is quite thoughtful, and it makes sense to hear what you say, but we are just talking about it on paper now, and no one knows whether it will save more effort and be more useful."
Li Zexuan really wanted to tell him that these are based on theory. Draw a force analysis diagram and do some calculations based on the formula, and you can know which one is more labor-saving. However, if you tell them this, you have to popularize the knowledge of engineering mechanics with them. This thing cannot be explained clearly in just a few words.
Li Zexuan could only say: "Uncle Fu, what you said makes sense, but practice is the only criterion for testing truth. Instead of arguing here, why not make a batch and test it first, and then you will know that the kind of plow is more labor-saving." Yet?"
Uncle Fu couldn't help but said: "Practice is the only criterion for testing truth. What you said, Xiaoxuan, makes sense. Let's make one first and try it out."
Li Zexuan cupped his hands and said with a smile: "Then Uncle Lao Fu will make twenty curved-column plows first. My village is in a hurry to use them. I will take this batch of curved-column plows to Zhuangzi the day after tomorrow for a test."
Uncle Fu frowned and said, "Xiaoxuan, you want to make so many things for the first time?"
Li Zexuan smiled confidently: "Uncle Fu, I have great confidence in Quyuli. The farmers in Hanjiazhuang are waiting for spring plowing. I don't have time to try them one by one. I believe Quyuli can solve the current urgent need."
Uncle Fu hesitated for a moment, nodded and agreed: "Okay, since you said so, Xiaoxuan, the workshop will work overtime in the past two days to make twenty curved shaft plows. I will go to Hanjiazhuang with you the day after tomorrow to see how it works. "
"I also need to go."
Yan Shaoning quickly added. If this Quyuanli is as magical as Li Zexuan said, then this will definitely be a major event that shocks the government and the public, and he must go and see it in person.
The third update, I feel like my body has been hollowed out!
