Fortunately, it is beautiful these days, there is no rain, and after a few days of exposure, the valley has basically dried up. (138.com.) At this time, there is also a very important work, which is to clean the rice and remove the bran debris, leaving the full and firm grains. In Chujiazhai, this work is called Wind Valley. This requires the use of a tool that is very commonly used in rural areas, that is, fan trucks.

"Come over and help, carry the fan cart out." Chu Jiaqiang said to Chen Wu and the others.

The second uncle picked up the rice that had been completely dried up in the grain flat and started the wind valley. In some places, such as Mikizhuang, people pick up the river to float directly before the sun, which can also achieve that effect. The grains that are not full and firm and some debris will float out of the water, and with the river water drifting away, the basket will be left full.

"I found this thing in almost every rural area in China!" Chen Wu has also been to a lot of rural areas, and almost everywhere, he will see such a farm tool.

On the right side of the wheel axle, fan blade plate and crank rocker, is a special circular air cavity, the circular cavity around the crank shaker is the air inlet, and there is a rectangular air duct on the left, the rice from the funnel passes through the air duct through the bucket valve, the full and firm grain falls into the grain outlet, and the bran debris floats out of the air outlet along the air duct with the wind.

"Of course, this kind of closed windmill may have been produced in the late Western Han Dynasty and has been used in remote villages today." Hong Lao is very familiar with these histories. Many of these antiquities, he can tell their history at a glance. In the opinion of Li Quan and others, it feels that people who play antiques are very knowledgeable.

In addition, some scholars even believe that one of the surprising features of the Chinese rotary fan car is that the air inlet is always located in the center of the air cavity, so it is the ancestor of all centrifugal compressors.

Lift the fan cart out and set it up. Chu Jiaqiang asked Chen Wu to help again, and poured a basket of grains into the funnel at the top. At the mouth of the valley below is an empty basket, where the full and firm grains are waiting.

"The one above is like those hourglasses!" Chen Xiang said.

"It's originally made according to the principle of an hourglass, can't it be like?" Zhou Furong replied.

The butt behind the fan car, there is also a leak, and a basket is also placed, and the valleys that fall here are not strong enough, but they are still useful. Such grains are often floured and used to feed livestock.

The big air outlet at the back of the fan car is the air outlet and those chaff debris. Those things are useless, and they are often dumped into cattle pens by farmers, where they are left to ferment with cow dung and eventually become farm fertilizer.

"How? I'll give it a try. Li Quan walked over, shook the crank and shook his hand, and the fan car began to turn.

"Don't shake it so hard, the wind is too strong, even the full grains are blown away by the wind?" Chu Jiaqiang said to him.

He asked Li Quan to get out of the way first, and he showed himself first, about how much force to use, that is, to turn the crank and shake the hand at about the same speed. The speed is too slow, the blades rotate slowly, and the wind force is small, so the effect cannot be achieved. If you turn too fast and the wind is too strong, it won't work. Therefore, don't look at the very simple operation, but people who have no experience still can't do it.

Chu Jiaqiang first shook the crank and shook his hand, waited for the wind to reach a certain level, and then opened the valve with the other hand, so that the valley of the funnel above leaked out of the valve mouth, and after the tuyere, the wind generated by the fan car blew out the valley that was not real enough. The plump one is straight

Falling, down the mouth of the valley, into the basket.

"Do you understand?" Chu Jiaqiang asked.

Li Quan nodded hurriedly: "Yes!" Got it! It doesn't bother me. He hurriedly assured that Chu Jiaqiang's operation just now was very small, and the main thing was to grasp a strength.

Chu Jiaqiang closed the valve easily, and then gave up his position and let these people who wanted to try it give it a try.

Chen Wu moved quickly, and immediately stood in Chu Jiaqiang's position just now: "Haha! I'll come first, you wait. ”

"Trouble! Hurry, give you two minutes. Li Quan had no choice but to wait for this scoundrel, anyway, there were more than 20 grains, and there were still many opportunities.

As soon as Chen Wu went up, he opened the valve first, and it was still very large, and it was already exhausted. The valley above fell like water, and it didn't have time to pass the wind.

Chu Jiaqiang patted his head and forgot to remind. This tool has to shake the fan cart before the valve can be opened. Moreover, it should not be opened too much at the beginning, which affects the quality.

Chen Wu also knew that he was in trouble, so he hurriedly closed the valve and smiled at everyone.

Li Quan was not polite, and laughed directly: "I said Lao Wu, where are you playing?" ”

"Ahem! I didn't pay attention for a while, it was unexpected! Chen Wu immediately defended. Just now, I saw Chu Jiaqiang open the valve and shake the fan car, and for a while I didn't pay attention to which one came first and which came last.

"Don't laugh at people, I guess if you come, you may make the same mistake." Zhou Furong said.

This guy seems to be very fair, but everyone can see the smile on his face, and the most hateful thing is this guy. Not to mention Li Quan, it is himself, he may still make the same mistake, but he puts on an expert's face.

Chu Jiaqiang put the fallen valley back on it and did it again. With the experience of the previous car, this time it is much better, and the basket of valleys above is very smooth and all the wind is good.

Zhou Furong immediately squeezed over: "It's my turn, it's my turn, let's let go first, let go first." ”

Chu Jiaqiang didn't pay much attention at this time, so he let these guys toss, anyway, everything that should be said has already been said, if he still can't do it well, then he can't be blamed for not being able to teach.

Who knew that at this time, something happened again. Zhou Furong and Chen Wu carried a basket of rice that had not yet been blown and poured it into the funnel above, and found that the grain was falling down with a bang.

Everyone understood what was going on, the valve was not closed. Zhou Furong and Chen Wu instantly had a big red face, Zhou Furong was laughing at others just now! Chen Wu, on the other hand, made two mistakes.

Chu Jiaqiang directly didn't look at it, and said very weakly: "Let's wind again!" In the future, before putting the grain, you should see if the valve is closed, right? ”

"All of them are big-headed shrimp, remember! The simpler things are, the easier it is to make mistakes, mainly because you are lax and forget some details that you should pay attention to. Wan Lao told these young people about his philosophy of life again.

The second aunt cleaned the barn at home and checked whether it had been bitten by rats or so on. The barns in the countryside are one of the two favorite places for rats, and the other is the rice bucket.

Chu Jiaqiang picked up the well-weathered grain of Zhou Furong and others and poured it into the barn for storage. (To be continued.) If you like this work, you are welcome to register as a member to recommend this work, your support is my biggest motivation. )
