Chapter 326 Thresher and Winnower
The wall they planned to build was planned to be two steps high and half a step wide.
The width of the house wall is also half a step, which can better keep warm and bear weight, but the height of the wall is three and a half steps.
After a section of the wall is built, someone needs to use large and small clappers to make the wall surface smooth.
Don't leave any gaps.
After working continuously for a whole day, thousands of people worked until dark. After dinner, everyone in Tangjia Village dispersed.
But the people of the Jiu clan still had to continue working. Needless to say, the women were sewing new clothes one by one, and their eyes were red from working day after day. Fortunately, they had a lot of candles, and sometimes they even lit a bonfire in the yard.
The men were also divided into several groups. Some of them used some of the yellow paper that Shen Youyou brought back to fold gold ingots. Although it was not the modern paper with gold and silver foil, that kind was too expensive and was now only affordable for the nobles.
They just used ordinary yellow paper to fold it, but everyone was very careful and the ingots they folded were very neat.
In addition, Shen Zhiqiu and his elder brother-in-law were studying threshers. Shen Zhiqiu had seen this thing in his previous life, but he had never made it himself.
The wooden thresher is composed of a frame, a rotor, a screen, an inlet, an outlet and other parts.
The frame is the main structure of the wooden thresher, carrying components such as the rotor, screen and transmission device.
The rotor is the core component of the wooden thresher. Its rotation creates centrifugal force, which separates the grain from impurities.
The sieve is used to screen grains and impurities, and is usually composed of multiple layers of fine and coarse holes.
The feed port is where the grains to be processed are put into the machine, and the discharge port is where the processed grains and impurities are separated.
Although it is made of wood, Shen Zhiqiu asked Shen Tietou to make the screen out of iron, so that the machine can be used for a longer time.
The only regret was that although the first thresher was made, they had not yet found any grains that could be threshed.
Shen Zhiqiu said, "Let's wait and see tomorrow whose wheat matures earlier. Let's harvest some and try."
Although Wang Fuxi made a thresher for the first time, he still had some questions: "Looking at the structure, successful threshing should not be a problem, but whether it is wheat or rice, there is also husk. It would be great if this thresher could also separate the grains from the husk."
Shen Zhiqiu was stunned. How could he have forgotten about this? He started looking for his daughter because he remembered the grain winnowing machine again.
He can't do the drawing.
Originally, Shen Youyou was learning how to sew clothes from her mother and grandmother. Although she was not as fast as her sisters, she could sew dense stitches if she was more careful, but her efficiency was relatively low.
But to be honest, she really doesn't like doing this kind of needlework, but what can she say?
She was a strong-willed person. She thought that others could do it, and that it was for the purpose of building a cenotaph for her grandfather, so her grandmother, aunts, and other cousins were all staying up late to do needlework. How could she not do it?
But the moment she heard her father calling her, she felt really good, as she could finally do something she was good at.
Shen Erya, watching her sister happily get off the kang and run out, couldn't help but burst out laughing:
"Sister, I knew Youyou didn't like sewing. Didn't you see the expression on her face when she was holding the needle and thread just now? Her face was almost wrinkled together."
Shen Daya smiled, she also realized that grandma just said that Youyou didn’t have to do this, and could find something she was good at, but her sister still looked like she could do this, too.
Taohua's voice was soft, like a feather brushing across the tip of my heart: "Yoyo likes to make small things, but it doesn't include needlework. Have you been wearing men's clothes too much? Do you really think of yourself as a tomboy?"
This caused a group of sisters in the room to burst into laughter. There was no malice in this laughter. It just made them see for the first time that the omnipotent Shen Youyou also had things she was not good at.
Shen Youyou was completely unaware of her sisters' teasing. She was already painting the various parts of the Yanggu machine under the guidance of her father.
The main reason was that she had only seen this thing on the Internet, and had only seen its appearance. She had no idea about its internal structure, but based on its function, it was not difficult to guess its general structure.
Winnowing machine, also known as wind winnowing car, winnowing device.
It is a traditional wooden farm tool specially used to remove impurities, empty grains, straw scraps, etc. from the seeds of crops such as rice.
Its basic structure is: there is a trapezoidal feeding bin on the top, a funnel below to discharge the rice, and a small funnel on the side to discharge the fine rice and shrunken grains.
The tail is for removing the husks; the wooden round "big belly" hides an impeller with an iron crank handle. The blades are turned by hand to blow the grains. The faster the rotation speed, the stronger the wind produced, and vice versa.
What they are going to make is a rotary winnowing machine, which is powered by human power. Its function is to remove the bran and husks after pounding and grinding, or the chaff and grass after threshing and drying. It is the final step in grain processing.
It uses the principles of fluid mechanics, inertia, leverage, etc. to artificially force air flow. It was once a "high-tech" in the history of agricultural tools in the world in the past.
Shen Zhiqiu chose this style because he knew that there were already similar farm tools like winnowers, but they were difficult to operate and did not remove husks and other things very cleanly.
That's why he wanted to make an improved version of this in the 1970s and 1980s.
Because this model is a more practical style made after countless ancestors’ experiments, and it has many uses.
As for the Daqing Dynasty, most people still used the traditional winnowing method.
For example, after harvesting and threshing, traditional methods of separating chaff, broken rice stalks and grains include winnowing, winnowing and sifting.
Winnowing involves throwing the grain into the air, preferably when there is a strong wind, so that the chaff is blown away and the grain falls to the ground.
As for the winnowing method, the grains are placed on a winnowing basket and then the wrist is shaken rhythmically to separate the chaff from the heavy grains. That is, the chaff is gradually winnowed to the front edge of the winnowing basket, while the grains remain at the back of the winnowing basket.
The final method of sifting grains is to use a sieve to separate the grains from the chaff and broken rice straw.
This is mainly because the kind of large and bulky winnowing machine that Shen Zhiqiu remembered is not very easy to use, but its cost is very high. Maybe there are some in Tangjia Village, but there are definitely not many.
Therefore, it is better to make this new type of winnowing machine as soon as possible. After all, seeing the people of Tangjia Village working so hard to build houses for them.
How can they hide things when others are sincere to them?
After finishing the drawings, it was already very late and it was almost time for those who were making the clothes to rest. Everyone fell asleep with tired bodies but satisfied hearts.
The next few days were basically spent in this cycle, with each day being busy and fulfilling.
As a result, the walls and house surfaces were raised higher day by day, making them feel that all their efforts were worth it.
