A small harvester looks like a walk-behind lawnmower, although from the structure to the principle, there is almost no difference between the two. Even a hand-held lawnmower can be transformed into a harvester with slight modifications. , but there are still some differences between the two.
In particular, Chen Xin's mini combine harvester comes with a threshing function and is quite different in appearance.
The principle of both is to use the engine to drive the blade to cut the stems of the plants. However, the weeder needs to adjust the height of the blade as needed to avoid cutting the lawn too bald, while the harvester needs to increase the blade appropriately and increase the cutting speed. Upper guide leaves for better cutting of crop stems.
When using it, you only need to start the machine, then aim at the crops to be harvested, and then push it forward at a certain uniform speed.
This kind of small harvester has rollers and tracks at the bottom. As long as you hold the handle steadily, you can harvest crops smoothly without the possibility of deviation or deviation.
Compared with manual harvesting, mechanical harvesting has considerable advantages in terms of efficiency and cost. After all, people will be tired, but machines will not.
Chen Xin's model is too small, so it is hand-held. The slightly larger model even has a seat on it, so you can sit down and drive it. It can be said to be quite comfortable.
So when the upland rice in the field matured, Chen Xin had already filled up the small harvester with oil, started it, and was ready to harvest.
"Zizzi! Zizzi!" With the engine running, Chen Xin only needs to push the machine forward, and the sharp blade will quickly cut off the rice stalks.
In addition, Chen Xin uses an integrated combine harvester. The cut rice will be directly crushed and threshed under the action of the machine, turning into shelled grains in bags, leaving only the threshed rice on the ground. stalk.
Compared with traditional manual harvesting, which requires pulling the rice stalks with hands and then cutting the rice stalks with a sickle, this is really much simpler.
After all, what is harvested manually is the rice ears connected to the stalks, which need to be threshed again. Even with the help of a threshing machine, this is still a very arduous task.
But with a combine harvester, there is no such trouble. The cut rice can be directly processed into husked grains.
So when a ridge of rice was cut and the grains were put into the bag hanging next to the harvester, Chen Xin couldn't help but whistle happily.
He originally thought that harvesting rice would be a tiring job before he got a small farm machine. He didn't expect that it would be so easy after using the machine.
This naturally greatly enhanced his enthusiasm. He pushed the harvester and continued to harvest quickly, striving to cut all his rice fields within an hour.
The part that Chen Xin wants to harvest is not too much. Out of a total of only 200 square meters of land, there are still 50 square meters of land planted with carrots, so what he wants to harvest is only 150 square meters of rice fields.
However, although the small harvester makes the harvesting work very easy, Chen Xin still needs to lower his head, as if he is hunched over the armrest of the harvester? Because the height of the hydroponic planting tray above his head is really a bit low? As a result, he couldn't straighten up.
Of course, this is much easier and more comfortable than bending down to cut rice.
So it didn't take much time? Chen Xin finished cutting all the 150 square meters of upland rice.
The cut rice is also threshed by the combine harvester and placed in bags on the machine.
The bag was not sealed, but it was already full. Chen Xin tried to reach out to lift it, but it was so heavy that he could hardly lift it.
After harvesting, one hundred and fifty square meters of upland rice is filled into three huge sacks. On average, one bag weighs almost seventy or eighty kilograms.
Of course, these are grains that have not yet been shelled and need to be dried to dry the moisture before they can be stored for a long time.
Although it is not impossible to directly shell the rice and turn it into new rice, because there is still a lot of moisture, the rice grains are likely to break.
If this process was in the past, wouldn’t it be very troublesome? Just find a flat place and spread out the grains to dry the rice. As long as it is a flat cement floor, you can use it to dry the rice.
In the past, Chen Xin even saw farmers drying rice on the road, so this job mainly depends on the weather and is not specific to the location.
But now that the sun, the most convenient and direct source of heat, is gone, it is impossible to take out the millet and put it in the snow to dry. The only place where grain can be dried is inside the shelter.
Considering the lack of space inside the shelter, Chen Xin decided to use mechanical drying to remove moisture from the grains instead of natural air drying.
Although the taste of mechanically dried grains will become worse, it is better than leaving the rice like this to cause mildew or germination.
As for how to carry out mechanical drying? Is there a continuous heat source like a ground source heat pump? This problem is not difficult to solve.
Whether you use a tray to bake or use a blower to blow hot air, you can remove moisture from the rice.
After struggling to move the three sacks out of the greenhouse, Chen Xin did not put the three sacks of rice into the storage room. Instead, he opened the bags and placed them in the public space.
Before the dryer is built, the rice cannot be stored in the warehouse, so leaving it open is the correct way to handle it.
As for making a dryer, Chen Xin was a little scratched his head. He had neither done nor seen this thing before.
Even with the information on the computer, no relevant pictures or text descriptions were found, which made Chen Xin very worried.
How to do this thing? Is it really necessary to get a big tray for baking
However, Chen Xin only gave up this idea after thinking about it for a while, because it was really unreliable. After all, if the temperature is low, it will not dry out if the temperature is low. If the temperature is too high, the rice will be cooked directly. , that would be embarrassing.
However, after thinking hard, Chen Xin remembered the clothes dryer he had used and the home dryer his mother had used before.
The principle of both is to use relatively high-temperature air to dry moist items and remove moisture in a relatively closed space.
Can you make something similar and use it to dehydrate grains
Chen Xin thought about it and felt that this method should be feasible, but before doing it, he still planned to draw a drawing to study it carefully.
After all, I have never practiced it before. If I start directly, it will be a small matter if things are broken. At worst, I can use the system to dismantle and recycle the materials. But if the grains are damaged, then I will lose at least one-third of this year's harvest.
So to be cautious, Chen Xin decided to draw the drawings of the equipment first, and then carefully study the feasibility. (End of chapter)
