Chapter 69: Questioning

Quirky Pavilion Workshop.

"Xiao Xuan, old man, I speak more straightforwardly, don't be surprised, although your scooter is creative and novel, but in the final analysis, this thing is just a child's play, and it is not beneficial to people's livelihood." Your roller bearing is of great use, and since you have a talent for it, study more things that are beneficial to the people. ”

After Fu Bo saw a few people sitting down, he began to preach to Li Zexuan in a serious manner. Li Zexuan was speechless, this old man's temperament is really straight enough, if he changes to a person with a small belly, he will definitely hate him in his heart.

But fortunately, Li Zexuan is not this kind of person, and he still agrees with Fu Bo's words.

"The lesson of Fuber is that this scooter is just a plaything that I thought about in order to coax my sister, and of course I won't just do this in the future."

Fu Bo nodded with satisfaction: "Well, the son can be taught." ”

Li Zexuan remembered another purpose of coming to the workshop this time, so he said: "Yesterday I went to my Zhuangzi and found that this year's fields are particularly difficult to cultivate due to the lack of rain. ”

Yan Shaoning's face was solemn, and he said in a deep voice:

"This situation is not only happening in your Zhuangzi, the surrounding counties of Chang'an have more or less this situation, according to my father, this matter has alarmed the imperial court, His Majesty has also learned of this matter, is asking people to transfer a batch of ploughing cattle from several states and counties in the north to Chang'an, and then distribute it to the farmers, try not to let the farmers miss the spring ploughing."

Fu Bo also nodded and said, "The old man has also heard about this, but Xiao Xuan, what is your intention in mentioning this matter?" We can't help much with this kind of thing, so we can only rely on the imperial court. ”

Li Zexuan stood up and disagreed: "Fu Bo's words are wrong, as the so-called workers want to do their jobs well, they must first sharpen their tools, as a craftsman, you must also have the spirit of craftsmen, you just educated the boy, to study more things that are beneficial to the people's livelihood, so why can't we make more useful farming tools for the people?" ”

Fu Bo raised his eyebrows, he had been in this field for so many years, but today he was preached by this little doll, he was a little displeased, and he frowned:

"What you kid said is light, the straight plough I used in the Tang Dynasty originated in the Han Dynasty, and after several improvements, it is already the most advanced tillage tool, how can there be a better ploughing tool than this."

"What Fubo said, the kid doesn't dare to agree, how can the craftsman not seek innovation, how can he do the things of the predecessors planting trees and the future generations enjoying the shade, how can he know that he can't make better farming tools without trying?"

Fu Bo was unconvinced: "So, you can make better farming tools?" ”

Li Zexuan also saw that this old man was stubborn, not that he had a bad heart, but he didn't allow others to question him in the field he was best at.

At that moment, Li Zexuan didn't talk nonsense, and directly took out the drawings of the Quyuan plough that had already been drawn from his sleeve, spread them out on the table, and said to the two of them:

"This is a more labor-saving plough that I saw in Hanjiazhuang yesterday when I saw the farmer using a straight plough to plough the land, and I accidentally thought of a more labor-saving plough, and today I am trying to find a workshop to make a batch as soon as possible. Brother Shaoning, Fu Bo, come and have a look. ”

Yan Shaoning and Fu Bo couldn't wait to come over and look at the drawing. When Fu Bo saw this kind of drawing technique for the first time, he couldn't help frowning, and wanted to ask Li Zexuan, but he was a little embarrassed to ask, he had just quarreled with Li Zexuan, and he really couldn't pull his face.

Yan Shaoning was very familiar with this kind of painting, he carefully read the content of the drawing, and then closed his eyes and meditated, imagining the structure of this plough in his mind, but after a few breaths, he opened his eyes.

"Xiao Xuan, your plough should have evolved from the straight plow, right? I see that you have made changes to the length and shape of the plough wheel, and you have installed a wheel wheel on the head of the wheel, which I have never seen before, and I cannot say which is more labor-saving than your plough or the straight plough we use. ”

Fu Bo saw that Yan Shaoning was talking about the Tao at this time, obviously he could understand this kind of drawing, Fu Bo couldn't help but be very depressed, he has been a craftsman all his life, and he also has his own pride in this field, but he didn't expect that today, it seems that it is not as good as these two little dolls.

In fact, after Yan Shaoning finished speaking, he noticed that Fu Bo was still staring at the drawings there, and after a little thought, he understood what was going on. He patted his head and said embarrassedly:

"Eh, Fu Bo, I forgot to tell you that this drawing method was created by Xiao Xuan. These three drawings represent the shape of the object as seen from three directions......."

Yan Shaoning began to popularize the knowledge of three views to Fu Bo again. Fauber has been studying this field for so many years, and he understands it all with a little dialing. Even though he disagreed with Li Zexuan's views before, he also somewhat agreed with Li Zexuan's drawing method at this time.

He nodded, and looked back at the picture.

Li Zexuan also explained at this time: "Fu Bo, Brother Shaoning, I call this kind of plough Quyuan plow, which is composed of eleven parts, namely ploughshare, plough wall, plough bottom, pressure plough, strategy forehead, plow arrow, plough wheel, plough comment, plough building, plough tip, and plough. ”

Li Zexuan pointed to the drawings and explained them one by one as he spoke, and both of them listened to him with a serious face, even though they could understand the drawings, but in terms of their understanding of this qu yuan plow, they would definitely not be able to catch up with Li Zexuan.

Li Zexuan continued: "I changed the long straight wheel to a short curved wheel, and installed a plow plate that can rotate freely at the head of the wheel, which not only makes the plow frame smaller and lighter, but also easy to turn and turn, flexible operation, and more saving manpower and animal power. ”

"In addition, I also added the plough evaluation and plough arrow, if you use the propulsion plow evaluation, then you can let the plough arrow down, the ploughshare into the soil will be deeper, if you lift the plow evaluation, so that the plow arrow up, the ploughshare into the soil will be slightly shallow, the plow evaluation, the plough arrow and the combination of the plough arrow, you can adapt to the different requirements of deep ploughing and signing the tillage."

"The plough wall not only breaks the soil, but also pushes the ploughed soil to one side, reducing the resistance of the plough forward. Combining these improvements, the curved plow is at least more than 50% less labor-saving than the straight plow. ”

Li Zexuan talked eloquently about the drawings, and the two nodded frequently while listening, and finally Fauber couldn't help but say:

"Your design is quite thoughtful, and it makes sense to hear you say that, but we're just talking about it on paper now, and no one knows if it's more labor-saving and easier to use."

Li Zexuan really wanted to say to him that these are theoretically based, draw a force analysis diagram, and calculate a little according to the formula, you can know which one is more labor-saving, but if you tell them this, you have to popularize the knowledge of engineering mechanics with them, and this thing can not be explained clearly in a word.

Li Zexuan could only say: "Fu Bo, what you said is not unreasonable, but practice is the only criterion for testing the truth, instead of arguing here, it is better to build a batch and test it first, don't you know that the plough is more labor-saving?" ”

Fu Bo couldn't help but say: "Practice is the only criterion for testing the truth, Xiao Xuan, what you said is very reasonable, then let's make one and try it first." ”

Li Zexuan arched his hand and smiled: "Then Lao Fubo will make twenty curved plows first, and my Zhuangzi is in a hurry to use them." The day after tomorrow, I will take this batch of quyuan plows to Zhuangzi for an experiment. ”

Fu Bo frowned and said, "Xiao Xuan, how much do you have to build this for the first time?" ”

Li Zexuan smiled confidently: "Fu Bo, I am very confident in Quyuan Plow, the farmers of Hanjiazhuang are waiting for spring ploughing, I don't have time to try them one by one, I believe that Quyuan Plough can solve the urgent needs of the moment." ”

Fu Bo hesitated for a moment, nodded and agreed: "Okay, since Xiao Xuan said so, the workshop will work overtime in the past two days to make twenty curved plows." The day after tomorrow, I will go to Hanjiazhuang with you to see how the effect is. ”

"I'm going too."

Yan Shaoning hurriedly added. If this Quyuan plough is really as magical as Li Zexuan said, then this will definitely be a major event that will shake the government and the opposition, and he must go and see it for himself.
