The small harvester looks like a walk-behind weeder, although there is almost no difference between the two in terms of structure and principle, and even a walk-behind weeder can be transformed into a harvester with a slight modification, but there are still some differences between the two.

In particular, Chen Xin's miniature combine harvester with threshing function is quite different in shape.

The principle of both is to use the engine to drive the blade to cut the stalk of the plant, but 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 add guide blades to better cut the crop stalks.

When you use it, you only need an engine, and then aim at the crops that need to be harvested, and then push forward at a certain constant speed.

This small harvester has rollers and tracks at the bottom, as long as the hand holds the handle steadily, it can achieve smooth harvesting of crops, and there will be no possibility of running crooked or deviating.

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 one is too small, so it is a hand-held type, and there is even a seat on it that is a little bigger, which can be opened by sitting and driving, which can be said to be quite comfortable.

So when the upland rice in the field matured, Chen Xin had already filled the small harvester with oil and was ready to harvest after it was launched.

"Zizizi! Zizizizi! With the engine running, Chen Xin only needs to push the machine forward, and the sharp blade will quickly cut off the stalks of the rice.

In addition, Chen Xin uses an integrated combine harvester, and the cut rice will be directly crushed and threshed under the action of machinery, turning into shelled grains packed in bags, leaving only the threshing rice stalks on the ground.

Compared to traditional manual harvesting, which requires holding the rice stalk by hand, and then using a sickle to cut the rice stalk, this is really much simpler.

After all, it is the ears of rice that are connected to the stalks that are harvested by hand, and another threshing is required, which is a very heavy job, even with the help of a threshing machine.

However, there is no such trouble with a combine harvester, and the cut rice can be directly processed into husked grains.

So when a ridge of rice was cut and the grains were in the bag hanging next to the harvester, Chen Xin couldn't help but whistle happily.

Originally, before he switched to small agricultural machinery, he thought that harvesting rice would be a very tiring job, but he didn't expect that it would be so easy after using machinery.

This naturally greatly strengthened his enthusiasm, pushing the harvester to continue 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, a total of only 200 square meters of field, there are still 50 square meters of land planted with carrots, so what he wants to harvest is only 150 square meters of rice field.

However, although there is a small harvester, which makes the harvesting work very easy, Chen Xin still needs to keep his head down, as if the whole person is lying on the handrail of the harvester with his back hunched, because the height of the hydroponic planting tray above his head is really a bit low, which makes him unable to straighten his waist.

Of course, this is much easier and more comfortable than bending over to cut rice.

So it didn't take too much time, Chen Xin finished cutting all the 150 square meters of upland rice.

The harvested rice is also threshed by the combine harvester and packed into 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 barely lift it.

After the harvest of 150 square meters of upland rice, it was filled with three huge sacks, and an average bag was about 70 or 80 catties.

Of course, this is a grain that has not yet been shelled, and it needs to be dried and dried before it can be stored for a long time.

Although it is not impossible to directly peel the husk and turn it into new rice, there is still a lot of moisture, and the rice grains are likely to break.

This process would not be very troublesome in the past, find a place with a flat ground, spread out the grains to dry, as long as it is a flat cement floor, it can be used to dry rice.

In the past, Chen Xin had even seen farmers drying rice on the road, so this job mainly depends on the weather, not the site.

But now that the most convenient and direct heat source is the sun, it is impossible to take out the millet and dry it in the snow, and the only place where the grain can be dried is the inside of the shelter.

However, considering the lack of space inside the shelter, Chen Xin decided to use mechanical drying to remove the moisture from the grains instead of natural air drying.

Although the texture of machine-dried grains will be poor, it is better than leaving them there to cause mildew or germination.

As for how to carry out mechanical drying, there is a continuous heat source of ground source heat pumps, which is not difficult to solve.

Whether it's roasting in trays or blowing hot air with a blower, it's a way to dehydrate the rice.

After laboriously moving the three sacks out of the planting greenhouse, Chen Xin did not put the three sacks of rice into the storage room, but just opened the bags and put them in the public space.

Before the dryer is made, the rice cannot be stored in storage, so it is the right way to deal with it by leaving it open first.

As for making a dryer, Chen Xin scratched his head a little, he had never done this thing before, nor had he seen it.

Even if it was the information in the computer, there were no relevant pictures or text descriptions, which made Chen Xin very worried.

How to do this thing? Do you really have a big tray to bake?

However, Chen Xin only dispelled this idea after a while in his mind, because this is really a bit unreliable, after all, if you bake it, it is good to say that the temperature is low and it is not dry, in case the temperature is too high, it will be embarrassing to bake the rice directly.

However, after thinking about it, Chen Xin remembered the clothes dryer he had used and the household dryer his mother had used before.

The principle of both is to dry the humid items with relatively high temperature air in a relatively confined space to remove moisture.

Can you make something like that and use it to dehydrate the grains?

Chen Xin thought about it for a while and felt that this method should be feasible, but before he started, he still planned to draw a drawing to study it carefully.

After all, I haven't practiced it, if I get started directly, it's a big deal to use the system to disassemble and recycle materials, but if the grains are destroyed, then the loss is at least one-third of this year's harvest.

So for the sake of prudence, Chen Xin decided to draw the drawings of the equipment first, and then carefully study the feasibility.
