Rising: Ten Thousand Years Chapter 388: : Harvester

Li Zhen looked at the drawings and was silent for a while, then began to conceive the design of the compression ignition test in his mind.

After a while, I said: "You have a try, change the gears into belts."

"Belt?"

Ma Jianbin has a question.

Li Zhen said: "It is to connect the belt to the rotor and use the belt as power transmission. This should save a lot of labor, and the rotating shaft connected by the belt can use the mechanical lever to save labor. This will be easier."

Li Zhen explained the belt transmission power system to Ma Jianbin and others in detail.

If you want to use a belt to transmit power, then you have to rebuild the engine.

All previous engines transmitted power either through a crank connecting rod or a chain and gears.

But now under the enlightenment of Li Zhen, they learned a new thing - a pulley.

Belt pulleys are used in low-power engines, the efficiency is very high, and there are many advantages.

First of all, the transmission of power by the pulley is able to moderate the load shock. From another aspect, this can save labor.

Secondly, the transmission of power by pulleys is far less noisy than gear transmission or chain transmission.

The only downside is that the pulleys tend to slip.

But as long as the structure is designed well, it will have strong wrapping and high friction. Then the problem of slippage can be solved partly.

Li Zhen also said: "Finally, let's enlarge the distance of the rocker to achieve the same kind of labor-saving as the pressurized well. Add a long lever to make the hand-cranking method more labor-saving. It is best It can be easily compressed and ignited. If it is not possible, you can also break through the plan. Let’s not use the hand-cranked type, and use the pedal type.”

Ma Jianbin asked: "Pedal type?"

"The legs are more powerful than the hands. If you design the rocker in the shape of a pedal, wouldn't it be easier for others to step on it with their feet? It is less laborious than hand cranking."

Li Zhen also had a whim. The foot-operated Zhang Zhi didn't tell him, but he suddenly thought of it.

Unbeknownst to Li Zhen, this pedal structure was exactly the structure used by motorcycles in Zhang Zhi's era.

Motorcycles can be started electronically and have a backup pedal-operated compression ignition system.

Ma Jianbin left thoughtfully, redesigned the drawings, and redesigned the compression ignition test diesel engine.

He figured he'd have to study the pulley a little bit. This pulley opened up his mind a bit. In the past, everyone thought that the power connection between the rotating shaft and the rotating shaft was only safe with the use of gears and chains.

But now it is found that the belt can completely replace the chain transmission and gear transmission.

The problem of slipping is actually not as serious as imagined. As long as the adjustment is tight enough, the wrapping is strong enough. In fact, the transmission power of the belt is more stable than that of the chain gear.

Ma Jianbin and others went back to the furnace to study the compression ignition engine.

But another group of people researched the harvester.

To be honest, the harvester they researched made Li Zhen feel refreshed and exclaimed.

A giant, ten meters wide. Very big.

But it is completed, harvesting, threshing, separation and screening, one-stop operation.

Li Zhen never thought that they could develop such a harvester with so many functions and complete functions. You know, there are many precision parts involved, and there are many problems in it.

But they never expected that they would figure it out in just a few days.

The main developer of the harvester is a student of the Motor Academy. His name is Li Aibin.

After some research, I found out that Li Aibin lives in Nanzhou and has been dealing with farmland since he was a child. I am no stranger to rice cultivation and farm work. When I have a holiday, I will go home and help the family thresh millet.

According to Li Aibin: "Actually, the harvester is not as high-end and sophisticated as we imagined. As long as you master the principle of threshing millet, and on the basis of the existing mobile power, it is only a matter of time before this set is figured out. That’s all.”

"We need a power locomotive. The front end is like a rake that goes out horizontally. The edges of these rakes have sharp movable blades. With the chain transmission, these blades can vibrate quickly. Therefore, with blades A locomotive can drive past the rice fields and cut off all the rice it passes through.”

Looking at the drawing, Li Zhen listened to Li Aibin's words with concentration, sighing in his heart that this is simply a talent.

Li Aibin continued: "After the rice stalks are cut off, they will pass through the conveyor belt behind the iron rake. A narrower and narrower partition mechanism is set on the conveyor belt channel to make the rice stalks From a messy discharge shape to a neat 'vertical' shape. After passing through the conveyor belt, these vertically arranged rice will enter a separator."

Li Zhen said excitedly: "Tell me about this separator carefully."

"The separator is a vibrating device, which can be driven by an electronic motor or a gasoline engine. It is densely covered with iron thorns. When the rice stalks are violently shaken in the iron thorn container, the millet is naturally separated from the rice stalks. Separation. In this way, the millet is completely separated."

Li Zhen asked: "Where did the millet go after entering the separation vibrator? Where did the straw go?"

Pointing to the drawings, Li Aibin said: "The lower part of the container is a sieve, and only the sieved millet can pass through. And directly below the sieve is a granary~IndoMTL.com~ After the millet is separated by the vibrating machine, it is directly on the ground. It has entered the granary. The rice stalks cannot pass through the screen, so the rice stalks will be taken away by another mechanism, and then discharged out of the harvester and arranged neatly on the field after the harvester leaves.”

"But how is this straw taken away?"

"The bottom of the separator is the screen, and there is a layer between the screen and the separator. This layer is a device for taking away the rice stalks. It is two cylinders, and the cylinder is separated from the horizontal Plow rake. The two cylinders rotate to produce the effect of a gear. It will hold the rice stalk and move on the rear conveyor belt, and the big "gear" will definitely not be able to hold the much smaller millet, so the millet It will leak from above, and the rice stalks will be sent out."

Looking at this precise road drawing, Li Zhen was astonished.

There are really too many wizards in the Kyushu Academy of Sciences. It is difficult for Li Zhen himself to think of such a sophisticated one-stop idea.

Without Li Aibin's idea, I am afraid that there is really no way to research it so quickly, and a lot of experiments and theoretical foundations are needed.

But Li Aibin, who is imaginative and familiar with rice, unexpectedly broke through his thinking so quickly. Draw this heaven-defying blueprint.

It's not just Li Zhen who is shocked.

Most people in the mobile academy were shocked by Li Aibin. After they saw the blueprints and saw this precise and smooth one-stop device, they were so shocked that they were speechless.

Three years ago, not even a steam engine was known on this land.

Three years later, a student of Li Zhen designed a large harvester. A harvester that integrates harvesting, separation and screening.

Before I saw the drawing.

You tell others that there is a kind of machine driving across the rice field that can screen out all the millet one by one. Certainly no one would believe it.
