The two carpenters were overwhelmed by Xiao Han's bizarre anger and stood to the side looking at him blankly. It was the old and sophisticated Feng who heard something from Xiao Han's words.

patted Xiao Han on the shoulder, and Lao Feng also squatted next to him and persuaded him with good words: "Xiao Hou, dissipate your anger." It's not our fault that good things haven't been passed down, and it's not our ancestors' fault! Look at the past few hundred years, almost all of them have been wars, famines, foreign invasions! In this case, it is all too common for good things to be lost. We don't need to complain now, it is the responsibility of our generation to continue learning for the sake of the saints and to open peace for all generations! You see, if we make this thing that can get water when the car is overturned, future generations will also benefit, isn't that also a good thing? ”

Lao Feng was enlightened by his heart, and Xiao Han finally calmed down, but there was still some moisture in his eyes. After raising his hand and wiping his eyes with his sleeve, Xiao Han said angrily: "Stupid, it's not the car that overturned, it's the water truck......

"You ......" finally sent a good heart, but was scolded as a stupid person to his face! Lao Feng's hands turned into palms like hooks for a while, and it took a long time to suppress his anger, and he yelled at Xiao Han hatefully: "It's a water truck, it's a water wheel!" Then you hurry up and get it, why are you still stunned?! ”

Hurry up and plug your ears, so as not to be deaf by Lao Feng's yell! These bastards are not easy to learn at all! As the old saying goes: Accept someone as a teacher, this guy is good, kind enough to correct his mistakes and yell at himself......

Rubbing his ears, Xiao Han called out to the two carpenters on the side, pointed to the drawings on the ground and began to study the size and materials with the two of them. Lao Feng didn't understand much of this, so he saw the two carpenters nodding like chickens eating rice, and was about to ask when it would be made, but the two carpenters broke up in a hurry and ran away to prepare the materials.

Overturned, that is, the keel waterwheel in the carpenter's mouth. In fact, its structure is very simple, it is a chute, and some chain plates and gears are constructed.

It takes time to put the lower end in the water, and then step on or shake the gear by hand to drive the chain plate to push the water up from the chute.

The two carpenters are very excited to restore the legendary keel waterwheel, and the original idea of making money has long been thrown out of the clouds!

Got the best timber out of the warehouse! Take the ink fountain and bounce it on the line and start sawing!

The two of them were very fast, and with the help of Xiaodong and Stunned, a wooden chute about two zhang long was quickly made.

The chute is the main body of the waterwheel, and its process directly determines the efficiency of water lifting. When the carpenter carried the chute into the grass shed, Xiao Han deliberately came to touch the bottom and sides of it.

Very good, smooth on all sides! If you look at it with your eyes, every side is a straight line! The patterns of the wood planed with planers are very clear, and I have to say that the skills of these two carpenters are really good!

The main body is accepted, and the rest is the keel blade and transmission.

The blades are easy to solve, just cut out square wood chips according to the chute, even if the number is a little more, it doesn't take much effort, but wait until the transmission is here......

After experimenting twice, looking at the broken hemp rope and the leaves scattered all over the ground, Xiao Han finally had a headache!

In this time when there is no chain and no belt, it is really difficult to transmit the power and then drive this string of blades!

At first, Xiao Han also wanted to replace the belt with a few hemp rope and cow tendons and the like. But after only trying the resistance of the blade in the chute, Xiao Han decisively gave up this idea!

It's too laborious, even if the tendon can barely be pulled, it won't take too long, and a tool that can't be used for a long time is a chicken rib!

The belt won't work, but the chain will do! After all, in Xiaojia Zhuangzi, the original metal chain can already be artificially made, but the cost is ......

Thinking of the price he paid to build a chain, Xiao Han shook his head helplessly!

The water wheel was built for the farmer. It's not something that the rich and noble show off, if it's so expensive, who can afford it?

The start went smoothly, but when it came to the transmission, it was stuck! The project was put into standby in an instant.

Xiao Han squatted aside with his head covered and thought of a cheap and convenient way, while Lao Feng and the two carpenters took the wooden planks over and over again to simulate the process of carrying water in the chute.

Here in the paddy field, Xiao Han made such a big move. Naturally, many people watched, and even Sun Simiao, who had not gone out for a long time, glanced at him through the crowd.

However, these people are all watching the fun. The fart is useless, and the muttering is annoying, and the real way to find a way is to rely on the few inside.

Looking at the chute on the ground, the more Xiao Han thought about it, the more annoyed he became! I pulled my hair irritably, and I wanted to kick him!

It's a damn thing that is easy to think about, but when I actually do it, I find that it's so hard! Even if you know the principle, you can't do it without a suitable method!

But that's right, if it's really that simple, I guess it won't be lost inexplicably.

"Master Hou? Hou Ye? When I was annoyed, someone next to me suddenly shouted Xiao Han in a low voice.

When Xiao Han heard the scream, he turned his head angrily and asked the born person, "What's wrong!" ”

The old carpenter was taken aback by Xiao Han's attitude, and said in a whisper: "Master Hou, do you want to string these pieces of wood and then circle them around the chute?" ”

Xiao Han rubbed his head and said, "Yes! What, what do you have to do? ”

The old carpenter arched his hand and said to Xiao Han: "This, I don't dare to say if it's a good way, but we can give it a try!" ”

"Oh?" Xiao Han, who was annoyed and anxious, looked up at him fiercely and said, "You talk about it first!" If you can do it, you should be credited with a great credit! ”

"Hehe, that little one thanked Master Hou first!" The old carpenter's eyes were fascinated, and he first glanced at Xiao Han. Picked up a wooden stick from the ground and said, "Master Hou, look! There is no way to bend this single stick. But if you put two or three of them together, you can turn them around! Isn't it just that you have a headache that you have to work hard and can turn? Then let's find some short sticks and connect them with movable sticks! As for the wooden blades, wear them in the middle of the sticks and fix them! Do you think it will happen? ”

Xiao Han looked at the wooden stick in the carpenter's hand, and quickly simulated what he said in his mind, and suddenly felt that this method seemed to be a bit of a doorway!

The old carpenter was talking about a wooden chain, which was not as flexible as a metal chain, but it was perfect for this uncomplicated rollover! The key is that it has a low cost, it is backed by the Qinling Mountains, and there is no shortage of wood for nothing! When the time comes, won't you build as many planes as you want?

The transmission device had eyebrows, and other things suddenly became clear in Xiao Han's mind! Just add an extra layer of shelves to the chute, and then string a thinner stick in the middle of the wooden stick to let it snap into the wooden gear. As long as a person pushes the gears, the blades can run automatically on the track in the shelf! Depending on the size of this water chute, how much water can be pumped in an hour?
