The two carpenters were overwhelmed by Xiao Han's bizarre anger and stood aside blankly looking at him. However, the sophisticated 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, almost all were 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, but that it has overturned...
…”
"You..." You finally showed good intentions, but you were scolded as an idiot in front of you! Old Feng's hands turned into palms and hooks. It took him a long time to suppress his anger, and he yelled at Xiao Han angrily: "It's overturned."
, it’s a dumpster! Then hurry up and do it, why are you still standing there?!”
Hurry up and block your ears to avoid being yelled at by Old Feng! These bastards are not easy to learn at all! As the old saying goes: a person should be regarded as a teacher. This guy is good. He kindly corrects his mistakes and yells at himself...
Rubbing his ears, Xiao Han called out to the two carpenters beside him, pointed at the drawing on the ground and began to study the dimensions and materials with the two of them. Lao Feng didn't understand much of this, so he just saw the two carpenters eating rice.
He nodded and was about to ask when it would be finished, but the two carpenters broke up and ran away to prepare materials.
The rollover is what carpenters call a keel waterwheel. In fact, its structure is very simple, it is just a chute, and it is composed of some chain plates and gears.
Just put its lower end in the water, 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 quickly moved the best wood out of the warehouse! I put the ink fountain bullets on the line and started cutting and 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 craftsmanship 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, the three surfaces are all smooth! Compare it with your eyes and you will see that each 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's 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 experimenting twice, Xiao Han finally got a headache looking at the broken hemp rope and the leaves scattered on the ground!
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 use a few pieces of hemp rope, beef tendon or the like to replace the belt. But after only testing the resistance of the blades in the chute, Xiao Han decisively gave up this 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 definitely 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 was not something for wealthy people to show off to. If it was so expensive to build, who could afford to use it?
The start went smoothly, but when it came to the transmission, it suddenly got stuck! The project immediately entered a standstill 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, many people gathered to watch. 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. They are useless, and they are also muttering and annoying. It is those few inside who really want to find a solution.
Looking at the chute on the ground, Xiao Han became more and more annoyed as he thought about it! He pulled his hair irritably and wanted to kick him!
This damn thing seems simple when I think about it, but when I actually do it, I find that it is so difficult! Even if I know the principle, it still can't be realized without a suitable method!
But that's right. If it were that simple, I guess it wouldn't have been lost inexplicably.
"Master Hou? Master Hou?" Just as he was getting 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 quietly: "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, I will take credit for your great contribution!"
"Haha, thank you first, Lord Marquis!" The old carpenter's eyes were so happy that they were blurred. He bowed to Xiao Han first, then picked up a wooden stick from the ground and said, "Master Marquis, look
!This single wooden stick cannot be bent. But if two or three sticks are connected together, they can be rotated at will! Isn’t your headache that you need something that is both strong and able to rotate? Then let’s find some
Short wooden sticks, connect them with movable joints! As for the wooden blades, thread them in the middle of the wooden sticks and fix them! Do you like it?"
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!
What the old carpenter is talking about is 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 nothing missing.
Lack of wood! Will we be able to build as many racks as we want by then?
The transmission device had an idea, and other things suddenly became clear in Xiao Han's mind! Since the wooden rod can drive the leaf plate to run, then just add another layer of shelves on the chute. Then string a thinner small in the middle of the wooden rod.
The stick is stuck 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?
