Chapter 153

The small harvester looks like a hand-held weeder, although there is almost no difference between the two from the structure to the principle, and even a harvester can be transformed with a little modification of the hand-held weeder, but there are some differences between the two.

Chen Xin, in particular, is a miniature combine with threshing function, which is quite different in shape.

The principle of the two is to use the engine to drive the blade to cut the stem of the plant, but the height of the blade needs to be adjusted according to the needs of the weeder to avoid cutting the lawn too bare, while the harvester needs to increase the blade appropriately and add the guide blade to cut the stem of the crop better.

When using, you only need to start the machine, then aim at the crops to be harvested, and then push forward at a certain uniform speed.

This kind of small harvester has roller and crawler at the bottom. As long as you hold the handle firmly, you can harvest the crops smoothly, and there is no possibility of skew or deviation.

Compared with manual harvesting, mechanical harvesting has considerable advantages in both efficiency and cost. After all, people are tired, but machines are not.

Chen Xin's one is too small, so it's a hand-held one. Even if it's a little bigger, there are seats on it. It's completely comfortable to sit on.

So when the upland rice in the field is ripe, Chen Xin has filled up the small harvester with oil and is ready to harvest after it is started.

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

In addition, Chen Xin uses an integrated combine harvester, which directly smashes and threshes the cut rice under the action of machinery, and turns it into husked grain in a bag, leaving only the rice stalk on the ground after threshing.

Compared with the traditional manual harvesting, which requires holding the rice straw by hand and cutting it with a sickle, this is really much simpler.

After all, manual harvesting is connected to the stem of the rice, and it needs to thresh again. Even with the help of thresher, it is also a very heavy work.

But with the combine, there is no such trouble, cut down the rice can be directly processed into grain with shell.

So when a ridge of rice is cut and all the grains are in the bag next to the harvester, Chen Xin can't help whistling happily.

He thought that harvesting rice would be a very tiring job before he got a small agricultural machine, but he didn't expect that it would be so easy after using the machine.

This naturally greatly enhanced his enthusiasm, pushing the harvester to continue to harvest quickly, striving to cut all his rice fields in an hour.

Chen Xin doesn't have much to harvest. In a total of 200 square meters of land, there are still 50 square meters of land planted with carrots, so what he wants to harvest is just 150 square meters of rice fields.

However, although the small harvester made the harvesting work very easy, Chen Xin still had to keep his head down, as if he were lying on the armrest of the harvester with his back bent, because the height of the hydroponic planting plate on his head was a little low, so he could not straighten up.

Of course, it's much easier and more comfortable than bending over to cut rice.

So it didn't take much time for Chen Xin to cut all the 150 square meters of upland rice.

The cut rice is threshed by the combine and put into the bag on the machine.

The bag was not sealed, but it was full. Chen Xin tried to reach for it, but it was so heavy that he could hardly lift it.

One hundred and fifty square meters of upland rice are filled with three huge sacks after harvest, with an average of about 70 or 80 Jin.

Of course, this is the grain that has not been shelled. It needs to be dried and stored for a long time.

Although direct shelling into new rice is not impossible, but because there is still a lot of moisture, rice is likely to break.

If this process was in the past, it would not be very troublesome. Just find a place where the ground is flat and spread out the grain to dry. As long as it is a flat cement ground, it can be used to dry the rice.

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

But now the most convenient and direct heat source, the sun, is gone, and the millet can't be taken out to dry in the snow. The only place to dry is inside the shelter.

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

Although mechanically dried grains taste worse, it's better than putting them in this way to cause mildew or germination.

As for how to carry out mechanical drying, the continuous heat source of ground source heat pump is not difficult to solve.

Whether it is to bake with a tray or to blow hot air with a blower, it is a way to remove moisture from rice.

Chen Xin did not put the three sacks of rice into the storage room. Instead, he opened the sacks and put them in the public space.Before the dryer is made, the rice can't be stored in the warehouse, so it's the right way to open it first.

As for making a dryer, Chen Xin scratched his head a little. He had never done it or seen it.

Even the information in the computer, also did not find the relevant pictures or text description, which makes Chen Xin very worried.

How to make this thing? Do you really want a big tray to bake?

However, Chen Xin just gave up the idea after a while in his mind, because it's really a bit unreliable. After all, if it's roasted at a low temperature, it's OK to say that it's not dry. If the temperature is too high, it's embarrassing to bake the rice directly.

However, under the meditation, Chen Xin thought of the clothes dryer he used and the household dryer his mother used before.

The principle of both is in a relatively closed space, with relatively high temperature of air to dry wet goods, remove moisture.

Can you make something like this and use it to dehydrate the grain?

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

After all, I haven't practiced it. If I do it directly, it's not a big deal if things break down. If I use the system to dismantle and recycle materials, but if the grain is destroyed, the loss will be 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.
