Strange Interest Pavilion workshop.
"Little Xuan, I'm a straightforward old man, so don't be offended. Although your scooter is innovative, it's just a toy for children. It's not beneficial to the people's livelihood. Your roller bearings are very useful. Since you have talent in this area, you should study more things that are beneficial to the people. "
After they sat down, Faubert began to preach to Li Zexuan. Li Zexuan was speechless. This old man's temper was really straightforward. If it was a narrow-minded person, they would definitely bear a grudge against him because of this.
But fortunately, Li Zexuan wasn't that kind of person. He agreed with Faubert's words.
"Faubert is right. This scooter is just a toy I thought of to coax my sister. Of course, I won't only make this in the future."
Faubert nodded with gratification. "Well, you're worth teaching."
Li Zexuan remembered another purpose of coming to the workshop this time. He said, "Yesterday, I went to my family's farmstead and found that it's very difficult to plough the fields this year due to the lack of rain. It's estimated that some of the farmers will miss the spring plowing. Brother Shaoning and Faubert, do you know about this?"
Yan Shaoning's face turned solemn and he said in a deep voice,
"This situation doesn't only happen in your farmstead. It's more or less the same situation in the surrounding counties of Chang 'an. According to my father, this matter has alarmed the imperial court. His Majesty has also learned about it. He's ordering people to transfer a batch of cattle from the northern counties to Chang' an and distribute them to the farmers. He's trying his best not to let the farmers miss the spring plowing."
Faubert also nodded and said, "I've also heard about this. But Little Xuan, why did you mention this? We can't help much with this kind of thing. We can only rely on the imperial court. "
Li Zexuan stood up and disagreed. "Faubert's words are wrong. As the saying goes, if a worker wants to do a good job, he must first sharpen his tools. As a craftsman, you must have the spirit of a craftsman. You just taught me to study more things that are beneficial to the people's livelihood. Then why can't we make better farming tools for the people?"
Faubert raised his eyebrows. He had been in this field for so many years, but today he was being lectured by this little kid. He was proud and arrogant, he was a bit unhappy and frowned.
"It's easy for you to say. The straight plow used by the Tang Dynasty originated from the Han Dynasty. After several improvements, it's already the most advanced farming tool. How can there be better farming tools?"
"I don't agree with Uncle Fu's words. How can craftsmen not seek innovation? How can they do things like planting trees for their predecessors and enjoying the shade for their descendants? If they don't try, how can they know that they can't make better farming tools?"
Faubert was not convinced. "So, you can make better farming tools?"
Li Zexuan could also see that this old man was stubborn. It wasn't that he had a bad heart, but he didn't allow others to question him in the field he was best at. Li Zexuan had seen a lot of people like this in his previous life. Generally, all the big shots in various fields had this kind of bad habit.
Li Zexuan didn't talk nonsense. He directly took out the drawing of the curved plow from his sleeve, spread it out on the table, and said to the two of them.
"This is a type of plow that I thought of when I saw the villagers using the straight plow in the Han Village yesterday. It's a more labor-saving plow. Today, I'm looking for a workshop to make a batch as soon as possible. Brother Shaoning, Faubert, come and take a look. "
Yan Shaoning and Faubert couldn't wait to take a look at the drawing. It was the first time that Faubert saw this kind of drawing technique. He couldn't help but frown. He wanted to ask Li Zexuan, but he was a little embarrassed to do so. He had just quarreled with Li Zexuan, so he couldn't bring himself to ask.
Yan Shaoning, on the other hand, was very familiar with this kind of drawing technique. He read the contents of the drawing carefully, then closed his eyes and concentrated. He imagined the structure of the plow in his mind. After a few breaths, he opened his eyes.
"Little Xuan, this plow of yours should be an evolution of the straight plow, right? I saw that you made some changes to the length and shape of the plow shaft. You even installed a wheel on the shaft. I've never seen this kind of structure before. I can't tell which one is more labor-saving between your plow and the straight plow we use. "
At this time, Faubert saw that Yan Shaoning's words were clear and logical. It was obvious that he could understand this kind of drawing. Faubert couldn't help but feel depressed. He had been a craftsman all his life, and he had his own pride in this field. He didn't expect that today, it seemed that he wasn't as good as these two little kids.
In fact, after Yan Shaoning finished speaking, he noticed that Faubert was still staring at the drawing. He thought for a bit and understood what was going on. He patted his head and said embarrassedly:
"Uh, Faubert, I forgot to tell you. This kind of drawing technique was created by Little Xuan. These three drawings represent the shape of the object when seen from three directions … "
Yan Shaoning began to teach Faubert about the three-view view again. Faubert had studied this field for so many years, so he understood it all with just a little bit of explanation. Even though he didn't agree with Li Zexuan's point of view before, he now somewhat agreed with Li Zexuan's drawing method.
He nodded and looked at the drawing again.
Li Zexuan also explained at the side: "Faubert, Brother Shaoning, I call this kind of plow the curved shaft plow. It is made up of 11 parts, which are the plough share, the plough wall, the plough bottom, the plough press, the plough head, the plough arrow, the plough shaft, the plough judge, the plough construction, the plough tip, and the plough disk."
Li Zexuan pointed at the drawing and explained one by one as he spoke. The two listened to him seriously. Even if they could understand the drawing, they definitely couldn't compare to Li Zexuan in terms of understanding the curved shaft plow.
Li Zexuan continued: "I changed the long straight shaft into a short curved shaft and installed a plough disk that can rotate freely at the head of the shaft. Not only does this make the plough frame smaller and lighter, but it also makes it easier to turn and turn. It's more flexible to operate and saves more manpower and animal power."
"Also, I added the plough judge and plough arrow. If the plough judge is used, the plough arrow can be directed downwards and the plough share will go deeper into the soil. If the plough judge is used, the plough arrow can be directed upwards and the plough share will go deeper into the soil. By combining the plough judge, plough arrow, and plough arrow, it can adapt to the different requirements of deep plowing and plow."
"Not only can the plough wall break the soil, but it can also push the ploughed soil to the side and reduce the resistance of the plow. With all these improvements, the curved shaft plow saves at least 50% of the effort compared to the straight shaft plow. "
Li Zexuan looked at the drawing and spoke with assurance. The two nodded as they listened. In the end, Faubert couldn't help but say:
"Your design is quite innovative, and it sounds reasonable. However, we are only talking about it on paper. No one knows if it will save more effort or be easier to use."
Li Zexuan wanted to tell him that there was a theoretical basis for all of this. He just needed to draw a force analysis diagram and do some calculations according to the formula to know which one saved more effort. However, if he told them that, he would have to teach them about engineering mechanics. This was not something that could be explained in a few words.
Li Zexuan could only say: "Faubert, what you said is not unreasonable. However, practice is the only standard to test the truth. Instead of arguing here, why don't we make a batch of ploughs to test first? Won't we know which plough saves more effort?"
Faubert muttered: "Practice is the only standard to test the truth. Little Xuan, what you said is very reasonable. Then let's make one to test."
Li Zexuan cupped his hands and smiled: "Then I'll have to trouble Faubert to make twenty curved shaft ploughs. My village needs them urgently. The day after tomorrow, I'll bring this batch of curved shaft ploughs to the village for an experiment. "
Faubert frowned: "Little Xuan, you're making so many on your first try?"
Li Zexuan smiled confidently: "Faubert, I'm very confident in the curved shaft ploughs. The villagers of the Han Village are waiting for spring plowing. I don't have time to test them one by one. I believe that the curved shaft ploughs can solve this urgent problem."
Faubert hesitated for a moment and nodded: "Okay, since Little Xuan said so, then the workshop will work overtime to make twenty curved shaft ploughs. The day after tomorrow, I'll go with you to the Han Village to see the results. "
"I want to go too."
Yan Shaoning hurriedly added. If the curved shaft ploughs were really as magical as Li Zexuan said, then this would definitely be a shocking event. He had to go and see for himself.
