Li Rui said: "If there is no water flow to drive it, we can use human or animal power to drive it! If a car overturns, it will not be driven by the water flow. It will not be able to lift the water to a high place!"

Carpenter Chen felt that his brain was not big enough: "Use manpower or animal power to drive it? This... how to do this?"

Li Rui said: "It's very simple, just make a transmission device. This transmission device is roughly like this..." Then he picked up the quill pen and drew the pattern of the transmission device on the paper.

A quill pen is not the best choice for drawing. It's fine for writing, but it's a bit laborious to use for drawing. But now Li Rui can't find a better pen, so he can only make do with it. He can't use a brush.

Right? If you really let him draw with a brush, who knows what it will look like.

Although it was not very easy to use, I was able to draw the picture anyway, and all the details were quite accurate. Carpenter Chen was full of praise for this, and decided that he would never use a brush to draw pictures again, and would instead use a feather pen.

! A brush that uses a hammer is so expensive that it’s not easy to use for drawing! Last night he picked up Li Rui’s quill and tried it. It was hard and it was much easier to use than a brush for drawing! This feather caught

He can pluck a handful of ducks and geese, okay? The money to buy a quill can buy a basket of feathers! Besides, if the quill doesn't work well, he can still beat the one that doesn't live up to expectations.

If the poultry meal and the brush he bought didn't work, would he dare to beat up the boss?

I would never dare!

Therefore, quill pens are easier to use than brushes, and I will not accept any objection!

Zhuge Hui looked at the drawings and came to the conclusion after a little consideration: "The general structure is similar to that of a water mill, but it is not driven by water, but by human or animal power... The horizontal wheel is driven by human or animal power to do work, and then driven by gears.

More wheels produce greater force, and these forces are finally transmitted to the waterwheel through the shaft, driving the waterwheel to rotate...well, it's not very complicated."

Li Rui was surprised: "Have you ever seen this kind of machine?"

Zhuge Huixiao: "I dismantled two water mills a few years ago, so I have some impressions."

Of course I have an impression, after all, I almost got beaten - a stone mill is already very valuable these days, and a water mill that is much more complicated than a stone mill is naturally more valuable. Thanks to her success in putting the two water mills back together,

Otherwise, a beating is absolutely necessary.

The water mill had been invented during the Cao Wei period and spread to Liangzhou. Zhuge Hui was naturally familiar with it. She could see at a glance that the principle of this transmission device was similar to that of a water mill. The difference was that the water mill used

It is used to process rice noodles, and it is used to drive waterwheels.

No difficulty!

So, under her command, everyone started working hard.

This transmission device was not easy to make, and it took three days to complete it. After it was completed, Li Rui called a carriage, loaded all the accessories and transported them out of the city. He found a pond and directed the workers to lay it.

Then install the waterwheel with a strong bracket. Zhuge Hui directed the workers at the pond to assemble the transmission device on the spot, using a long wooden pole to connect to the waterwheel through a series of complex gears, bearings, shafts, and chains.

, connected to the waterwheel. The assembled waterwheel is nearly one foot above the water. According to common sense, there is no water. However, the waterwheel is covered with ropes and there are many small wooden barrels installed on the rope ladder. Each barrel can

It holds more than ten or twenty kilograms of water. A long series of small wooden barrels hang down from the top of the waterwheel and all the way into the water. It is a bit spectacular.

When everything was ready, the workers hitched the two horses that pulled the cart, and then waved their whips to drive them. The horses slowly circled around the transmission device that looked like a water mill. Because of the transmission device,

The workmanship is excellent, the errors between the various parts are very small, and the friction is reduced to the lowest possible level, so they appear to be quite easy to pull, as if they are walking in the wild. And as they move around in circles, the huge transmission device

The wheels were driven, and the gears and bearings also rotated rapidly. The force was transmitted to the waterwheel through the shaft. The originally stationary waterwheel immediately started to rotate briskly. As it rotated, the waterwheel fixed on the rope ladder

The barrels fell into the water one after another, and the turbid water in the pond was scooped into the barrels. Then they were taken to high places with the rotation of the waterwheel. When they reached the peak of the height, the barrels tilted and the water in the barrels poured out.

, fell into the wooden trough, splashing water. The small waterfalls falling from the sky merged into a small river in an instant, flowing out turbulently along the wooden trough that had been laid in advance, and soon dried up the pond.

The land became Zeguo!

Everyone cheered: "It's really amazing to bring up the still water! It's so amazing!"

Zhuge Hui was also very happy: "In this way, even stationary water can be lifted up with this waterwheel. With it, you will not be afraid of drought!"

Li Rui nodded: "Yes, as long as the irrigation facilities are complete and there is it, there is no fear of drought."

This is really not his fault. Most of the droughts in the Qing Dynasty were not because there was no water, but because the water level dropped and there was no way to divert canals for irrigation. What? You ask why we didn’t build a reservoir? It’s funny, water transportation in ancient times was also very important, okay?

, let you build the reservoir, will water transportation be necessary? Besides, there was no steel and concrete in ancient times. With those materials, the dam built with so much hard work will be immediately destroyed by the raging torrent in summer. What will happen next?

How to do it? You can’t repair it once a year, right? How much manpower and material resources will be wasted? So every time there is a drought, everyone basically has to ask God for rain. If God refuses to help, the whole family, old and young, will have to go to the battle together and carry water in buckets.

Water the crops in the field to see if you can preserve the harvest.

When the drought was at its worst, the rivers stopped flowing, and the people were basically desperate. Even if there was still a lot of water in the lakes, there was nothing they could do. In ancient times, there were no fertilizers or improved seeds, and the yield per mu was very low. In addition, taxes were heavy.

The common people have to cultivate dozens of acres of land to barely maintain their food and clothing. How much water is needed to water these dozens of acres of land? It’s fine if it’s close, but if it’s a little far away, the whole family will be exhausted and can’t water it!

There is obviously still a lot of water, but there is no way to use it. They can only watch large areas of crops withered and eventually failed. For farmers, there is nothing more desperate than this.

But with this waterwheel, it's different. Even if it's still water, it can pump it up as long as it has a certain depth. For a lake with an area of ​​one square meter, even if the average water depth is only one meter, it's 10,000 tons of water.

level, enough to irrigate many fields. Besides, the crops grown in the north are relatively drought-tolerant, such as millet and broomcorn millet. Even if there is not a drop of rain for a month, drought will not kill them. As long as they can grow in the most critical areas

If you water it at the right time, you will basically have a good harvest. There are many large and small lakes in Nanyang. The water stored in them is not enough to water the crops several times, right?

If it doesn't work, just dig a well, a well that is more than ten or twenty square meters in size and six or seven meters deep. Nanyang is very rich in groundwater resources. Digging such a well is equivalent to adding a small reservoir. Even the lakes have dried up.

You can use water trucks to pump out the water from these small reservoirs for irrigation as a last-ditch effort. No matter how terrible the climate of the small glacier is, it won't drain all the groundwater dry, his grandma!

Li Rui made up his mind, and later introduced a law to prohibit the reclamation of lakes for farmland and wetland reclamation. Those wetlands and lakes are natural reservoirs. In extreme drought climates, they rely on the water inside to save their lives. It really makes the people use them to save lives.

If you fill it out, you won’t be blinded!

Zhuge Hui, on the other hand, did not think so far. She was simply happy that she had made a new invention. In a happy mood, she sat directly on the long horizontal bar and followed the rotation of the rotating device pulled by two horses.

After playing the merry-go-round, Li Rui also observed the situation of this waterwheel driven by animal power with a happy mood. Watching it pull water ashore with amazing efficiency, he exclaimed: "Oh, this can hold up to 20 or 30 people."

What a strong man!"

Carpenter Chen smiled so hard that he couldn't see his eyes: "It can hold up at least forty strong men. After all, no matter how strong a man is, he can't scoop water all the time, but it can!"

Li Rui said: "It's just that this horse is not strong enough, it is expensive to eat, and its physical strength is easily exhausted. It is not cost-effective to use it as an animal."

An old carpenter said: "You can exchange it for cows. Cows are strong and eat rough food. As long as two cows take turns, they can drive the waterwheel to draw water all the time."

Carpenter Chen said: "Not every household has cows, but donkeys are better. Donkeys are available in almost every household and are not picky about food. They are perfect for this job."

Li Rui said: "I think camels are the best. There is no one more durable than a camel, and its food is not expensive!"

Zhuge Hui said: "Why do we have to use animal power? This thing is essentially the same as a water mill. Why don't we dig a channel to lead the water and let it hit the water wheel, let the water wheel rotate, and drive the water wheel to draw water?"

Li Rui slapped his thigh: "What a great idea!"

Zhuge Hui smiled sweetly: "Isn't this a good idea? Let me tell you, as long as the drop in this canal is large enough and the water flow is strong enough, then..."

Carpenter Chen asked blankly: "If the water can be directed to impact the water wheel, why not directly lead it into the river?"

Li Rui: "..."

Zhuge Hui: "..."

Both of them were dumbfounded.

Yes, you can divert the water to expel the water wheel, so why not just divert it out of the canal? Isn’t this just taking off your pants and farting? Isn’t it unnecessary?

Li Rui was stunned for a long time, then laughed dryly: "Well... what Master Chen said makes sense. Xiaohui, although you are very smart, you are a bit out of touch with reality. This is not good and must be changed!"

Zhuge Hui blushed and said angrily: "Am I out of touch with reality? But you just approved it with both hands!"

Li Rui pretended to be stupid: "Do I have it?"
Chapter completed!
