The two carpenters were overwhelmed by Xiao Han's bizarre anger and stood aside blankly looking at him. But the worldly old Feng heard something from Xiao Han's words.
Patting Xiao Han on the shoulder, Old Feng also squatted next to him to persuade him: "Xiao Hou, calm down. It's not our fault that good things have not been passed down, nor the fault of our ancestors! Look at the hundreds of people in the past During the years, there were almost all wars, famines, and foreign invasions! It is too common for good things to be lost under such circumstances. We don’t need to blame others now. It is the responsibility of our generation to carry on the unique knowledge for the saints and create peace for all generations. ! Look, if we build something that can draw water if a car overturns, future generations will also benefit from it. Isn’t this a good thing?”
After Lao Feng's sincere advice, Xiao Han finally calmed down, but there was still some moisture in his eyes. After raising his hand to wipe his eyes with his sleeve, Xiao Han said angrily: "Idiot, it's not that the car has overturned, it's that the water tanker has overturned..."
"You..." You finally tried to be kind, but you were scolded as a fool in front of you! Lao Feng's hands turned into palms and hooks. It took him a long time to suppress his anger and yelled at Xiao Han angrily: "It's a water truck, it's a water truck! Then hurry up and do it, why are you still standing there?! "
Hurry up and block your ears to avoid being deafened by Old Feng’s yelling! These bastards are not easy to learn at all! As the old saying goes: If someone is to be regarded as a teacher, this guy is good. He kindly corrects his mistakes and even yells at himself...
Rubbing his ears, Xiao Han called out to the two carpenters beside him angrily, pointed to the drawing on the ground and began to study the dimensions and materials with them. Lao Feng didn't understand much of this, so he saw the two carpenters nodding like chickens eating rice. Just when he was about to ask when it would be ready, the two carpenters broke up and ran away to prepare the materials.
The overturning car is what the carpenter calls the keel waterwheel. In fact, its structure is very simple, it is just a chute, and some chain plates and gears.
Just put its lower end in the water for a while, then step on it manually or shake the gear to drive the chain plate to push the water up from the chute.
The two carpenters were very excited to be able to restore the legendary keel waterwheel. The original idea of making money had long been forgotten!
I moved the best wood out of the warehouse in a hurry! Put the ink fountain bullet on the line and start sawing!
The two of them were extremely fast, and with the help of Xiaodong and Lengzi, a wooden chute about two feet long was quickly completed.
The chute is the main body of the waterwheel, and its technology directly determines the efficiency of water lifting. When the carpenter carried the chute into the hay shed, Xiao Han specially touched its bottom and sides.
Very good, all three sides are smooth! Compare it with your eyes and see that every surface is a straight line! The wood patterns planed with the plane are very clear. I have to say that the skills of these two carpenters are indeed good!
After the owner has passed the acceptance test, all that is left is the keel blades and transmission device.
The blades are easy to solve. You just need to cut out square pieces of wood according to the chute. Even if the number is larger, it doesn't take much effort. But when it comes to the transmission device...
After two experiments, Xiao Han finally got a headache looking at the broken hemp rope and the scattered leaves!
When there are no chains or belts, it is really difficult to transmit power and then drive this string of blades!
At first, Xiao Han wanted to replace the belt with a few pieces of hemp rope and tendons. But after only testing the resistance of the blades in the chute, Xiao Han decisively gave up the idea!
It's too laborious. Even if the tendon can barely pull, it won't take too long. A tool that can't be used for a long time is useless!
The belt method won't work, but the chain method will certainly work! After all, in Xiaojiazhuangzi, original metal chains can be made manually, but the cost...
Thinking of the price he paid to build a chain, Xiao Han shook his head helplessly!
The waterwheel was built to be used by farmers. It’s not something that wealthy people show off. If it’s made so expensive, who can afford it?
The start went smoothly, but when it came to the transmission, it suddenly got stuck! The project immediately entered a waiting state.
Xiao Han covered his head and squatted aside, trying to think of a cheap and convenient method, while Lao Feng and two carpenters used wooden boards to simulate the process of lifting water from the chute over and over again.
Here in the paddy field, Xiao Han made such a big noise. Naturally, it attracted many people to watch, and even Sun Simiao, who had not been out for a long time, took a look through the crowd.
However, these people are just watching the fun. It's useless, and it's also annoying with its muttering. The only ones who can really think of a solution are the few inside.
Looking at the chute on the ground, Xiao Han became more and more annoyed as he thought about it! I tugged at my hair in annoyance and wanted to kick him!
This damn thing seems simple when I think about it, but when I actually do it, I find it is so difficult! Even if you know the principle, you still can't implement it without a suitable method!
But that's right. If it were that simple, it probably wouldn't have been lost inexplicably.
"Master Hou? Master Hou?" When he was annoyed, someone suddenly called Xiao Han in a low voice next to him.
When Xiao Han heard the cry, he turned angrily to the person who was born and asked, "What's wrong!"
The old carpenter was startled by Xiao Han's attitude, and said softly: "Master Marquis, do you want to string these wood pieces together and make a circle around the chute?"
Xiao Han rubbed his head and said, "Yes! What, do you have any good ideas?"
The old carpenter cupped his hands and said to Xiao Han: "I can't say whether this is a good idea, but we can give it a try!"
"Oh?" Xiao Han, who was worried and worried, looked up at him and said, "Tell me about it first! If it can be done, you will be credited with a lot of credit!"
"Haha, I'd like to thank the Marquis first!" The old carpenter's eyes were so dazzled with joy that he bowed his head to Xiao Han first. He picked up a wooden stick from the ground and said: "Master Hou, look! This single wooden stick cannot be bent. But if you connect two or three sticks together, you can turn them at will! Isn't your headache just that you have to eat it at the same time?" Jin, do you want something that can rotate? Then let’s find some short wooden sticks and connect them with movable joints! As for the wooden blades, thread them in the middle of the wooden sticks and fix them! Do you think so?"
Xiao Han looked at the wooden stick in the carpenter's hand, simulating what he said in his mind, and suddenly felt that this method seemed to be a bit clever!
The old carpenter is talking about a wooden chain. Although it is not as flexible as a metal chain, it is perfect for use on this simple rollover car! The key is that its cost is low. It is backed by the Qinling Mountains, so there is no shortage of wood! Wouldn't it be possible to build as many aircraft as you want by then?
The transmission device became clear, and other things suddenly became clear in Xiao Han's mind! Since the wooden rod can drive the leaf plate to move, we only need to add an extra layer of shelves above the chute. Then string a thinner stick in the middle of the wooden stick and clamp it on the wooden gear. As long as people push the gear, the blades can automatically run on the track in the rack! According to the size of this water chute, how much water can be pumped in one hour?
