Doomsday Bunker Upgrade

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

In particular, Chen Xin is a miniature combine harvester with a threshing function, which 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 appropriately increase the blade and add Upper guide vanes for better severing of crop stalks.

When using it, you only need the engine, and then aim at the crop to be harvested, and then push it forward at a certain constant speed.

This small harvester has rollers and tracks at the bottom. As long as you hold the handle firmly, the crops can be harvested smoothly, and there is no 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 machine is too small, so it is hand-held, and a slightly larger one even has a seat on it, which can be completely seated. It can be said to be quite comfortable.

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

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

In addition, Chen Xin uses an integrated combine harvester. The cut rice will be directly crushed and threshed under the action of machinery, and turned into hulled grains in bags, leaving only the rice after the threshing is completed on the ground. stalk.

Compared with the traditional manual harvesting, you need to hold the rice stalks with your hands, and then use a sickle to cut the rice stalks. This is really much simpler.

After all, what is harvested manually is the ear of rice that is attached to the stalk, and it needs to be threshed again. Even with the help of a thresher, this is a very heavy work.

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

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

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

This naturally greatly strengthened his enthusiasm, pushing the harvester to continue to harvest quickly, and strive to cut all his rice fields within an hour.

Chen Xin didn't have much to harvest. Of the 200 square meters of land, there were still 50 square meters of carrots, so what he wanted to harvest was only 150 square meters of paddy fields.

However, although there is a small harvester, which 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 plate above his head is really low. It made him unable to straighten up.

Of course, this is 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 harvested rice is also threshed by the combine harvester and placed in a 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 barely lift it.

One hundred and fifty square meters of upland rice is filled with three huge sacks after harvesting, with an average of about seventy to eighty catties per bag.

Of course, this is the grain that has not been hulled, and it needs to be dried and dried for long-term storage.

Although it is not impossible to directly dehull it into new rice, because there is still a lot of moisture, the rice grains are likely to be broken.

If this process was in the past, it would not be very troublesome. Find a place with flat ground and spread out the grains for drying. As long as it is a flat concrete floor, it can be used for drying rice.

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

But now the most convenient and direct heat source, the sun, is gone, and it is impossible to take out the millet and put it in the snow.

Just considering the lack of space inside the shelter, Chen Xin decided to use mechanical drying to remove the moisture from the grains instead of drying them naturally.

Although mechanically dried grains will have a poorer taste, it is better than leaving the rice as it is to cause mildew or germination.

As for how to perform mechanical drying, it is not difficult to solve this problem with the continuous heat source of the ground source heat pump.

Whether roasting with a tray or blowing hot air with a blower is a way to remove moisture from the rice.

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

Before the dryer is made, these rice grains cannot be stored in the warehouse, so it is the correct way to deal with them.

As for making a dryer, Chen Xin scratched his head a little. He had neither done nor seen it before.

Even in the information on the computer, no relevant pictures or text descriptions were found, which made Chen Xin very worried.

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

However, Chen Xin dismissed this idea after just passing it through his mind, because it was a bit unreliable. After all, if the temperature is low, it is not dry. 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 used and the home dryer his mother used before.

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

Could something similar be made and used to dehydrate the grains?

Chen Xin thought about it 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 tried it myself. If I start it directly, it’s not a big deal if something is broken. It’s a big deal to use the system to dismantle the recycled materials, but if the grain is destroyed, then the loss will be at least one-third of this year’s harvest.

Therefore, in order to be cautious, Chen Xin decided to draw the drawings of the equipment first, and then carefully study the feasibility.

The small combine harvester is really good. It looks like a set of more than 10,000. The smallest model can be carried by two people, and it can be bagged after cutting, which is quite good.
