Chapter 1027 Glass Greenhouse
After the group finished talking about how to modify the excavator and the research and development of molybdenum steel, Luo Chong asked Lin Fei to take them to see the unfinished corn harvester.
Both corn and grain harvesters were modified on the platform of the loader. The huge bucket in front was removed, and then the working system of the harvester was transplanted on. The car was still the same car, but the function was changed.
According to Luo Chong's proposal, the dozens of motion modules in front of the entire corn harvester were all driven by aerodynamics, so that the large, heavy and very complicated hard transmission mechanism could be omitted.
Now a new loader body has been built and is being modified by the agricultural machinery research team and the pneumatic tool team. They installed an air compressor on the steam engine behind the body, and then laid a rubber hose to guide the high-pressure air to the front of the car.
The agricultural machinery group is responsible for designing the function and appearance, and the pneumatic tool group is responsible for developing the moving parts inside. In fact, there is nothing to develop. Just copy the internal structure of the existing "wind batch" and it will be fine.
The only difference is that the size needs to be changed, and a few more layers of air filters are added, because the working environment of agricultural machinery is different from those pneumatic tools in factories. The factories are mostly oily and iron filings, while the farmland has a lot of loose soil and straw debris. These things float in the air and are very likely to cause the air compressor valve to clog.
The current harvesting system has not been installed on the body, but is placed on a shelf next to it, powered by an external mobile air compressor. The motion module is checked there. The entire harvesting device has a simple prototype. Although it is ugly now, it has all the important parts. The outer layer of iron decoration is secondary.
"Can this thing automatically harvest corn? Can it thresh? What does the harvested corn cob look like?" You Fu asked with great interest.
"It can harvest corn, but it can't thresh it. Look at the row of reamers below. They can roll the corn stalks in from the roots, and then the corn will be cut off from the roots, and then the height will be quickly lowered. The row of iron bars can separate the corn cobs with skins, and then guide them to the back through vibration.
"Those corn stalks that are rolled in will be directly crushed and sprayed out, and the corn cobs with skins have to go back. Here is a roller bed for peeling the cobs. As long as the corn goes in, the skin will be rolled off by the row of steel rollers, and finally it will become a bare cob, and then it will be discharged directly from the side and piled into the basket." When Lin Fei heard You Fu's question, he immediately explained it.
Lu Guangzhu, She Xin and You Fu were all amazed and exclaimed in admiration, "Amazing, amazing, once such a machine is made, it will save a lot of manpower. "
No, we should talk about how much grain can be produced. With this, we won't have to worry about food anymore. With more food than we can eat, we can concentrate on development. The future of the Han tribe is promising. I don't know how powerful our tribe will be in the future." You Fu also said with emotion.
"Haha, I dare not say anything else, but in another ten years, there will be absolutely no problem for our population to double several times. "She Xin said very affirmatively.
Everyone nodded when they heard it. This population problem was clear to everyone. As long as there was food, coupled with the establishment of the fertility and medical system of the Han tribe, a population explosion was almost inevitable.
Not to mention that every family of childbearing age gave birth to one child a year, it would always be possible to have two children in three years. In that ten years, a couple of childbearing age could at least give birth to six children. Even if the number of women of childbearing age only accounted for one fifth of the total population, it was certain that the number would double in ten years at this rate.
Let's not talk about anything else, just talk about the generation of the people born in the 1950s and 1960s when Rabbit founded the country. Which family didn't have seven, eight, or nine children? It was also common for the uncle to grow up drinking the milk of his sister-in-law, the daughter-in-law and the mother-in-law to compete in giving birth, the eldest son was married and had children, and the mother-in-law was still giving birth after becoming a grandmother. Such things were no longer surprising.
You Fu and the others only saw the efficiency and convenience of the harvester and tractor, and knew that there would definitely be a lot of food in the future, but Luo Chong was thinking about another thing. The first thing was the potatoes Youfu brought back this time.
And what he brought back were not wild potatoes, but potatoes that the Baiwu tribe had domesticated and planted for who knows how many generations. The Han tribe did not need to domesticate or improve them again, and they could just use them directly.
With this thing, even if the Han tribe did not have tractors and harvesters, as long as potatoes were promoted, the Han tribe would no longer be at risk of starvation.
After seeing the harvester, Luo Chong took them to see the improved hand-cranked rice transplanter. The entire machine body was replaced with iron parts. The skid below was replaced with iron sheets, the columns were replaced with steel pipes, and the gears were replaced with thin iron hollow gears. Combined with steel chains, the weight of the whole machine was not only lighter than before, but also more durable.
It was just that it had not been actually operated in the field, so it was impossible to finalize mass production, but Luo Chong had already asked them to start stockpiling various parts. Once the experiment was completed, it could be mass-produced and promoted immediately.
"Chief, you should just wait patiently. We know you want to promote it earlier, but the season is something that cannot be rushed. No matter how anxious you are, you can't turn winter into spring." Lin Fei knew that Luo Chong wanted to promote the rice transplanter earlier, but the season was wrong, and they had no choice, so they could only comfort him in this way.
But what he didn't know was that his words just now reminded Luo Chong.
'Yes, why can't I turn winter into summer? No, I can obviously do it. Although there is no plastic film greenhouse at this time, I can use glass to make a greenhouse!'
Luo Chong was suddenly inspired by Lin Fei, and his mind immediately started to think quickly.
"Chief? Chief? What's wrong with you?"
Seeing that Luo Chong ignored him, he looked at the workers in the workshop in a daze, and immediately called him twice.
"Oh, I'm fine, but what you said just now is very right. Why can't I turn winter into spring? If it is spring now, can't I do the experiment immediately? You are right, I am going to do it immediately." Luo Chong came to his senses and said immediately.
"Ah?! ”
Everyone looked at him in shock. What was going on? The leader had this ability? He could even change the seasons at will? !
Luo Chong knew what they were thinking when he saw their expressions, and he explained immediately.
"It's not what you think. I'm going to make a test field, and then build a glass house on it. The walls, doors, windows, and roof are all made of glass, so that light can pass through from top to bottom. Then I'll light a stove inside and raise the temperature. Wouldn't it be spring in the house? Maybe it could even be summer."
Several people were stunned, all shocked by Luo Chong's idea.
"This, this works?!" She Xin said in shock.
"I think it's feasible. If we burn a kang in the house we live in, can't we also make the house feel like spring and summer? As long as the kang is burning in the house, there won't be any snow on the roof, which proves that the temperature in the house is high enough." Lu Guangzhu immediately said affirmatively after hearing this, expressing his support for Luo Chong.
"It's not that you think it's OK, it's definitely OK. My wife planted some flowers in the summer, and dug them out in the winter and planted them in pots. Now we keep them in the room where we sleep every day, and the flowers are still alive and well. Oh, by the way, my house has glass windows, and there is sunlight inside." Dali, who had not spoken for a long time, took the initiative to speak.
Xingang County is all saline-alkali land, and it is impossible to grow food. Food, meat and vegetables must be transported from other counties. The people here don't farm. All they see all day is either mines, iron, or machines. There is not even a bit of green in their eyes. So Dali's wife loves to grow flowers, and even the soil for growing flowers is dug from other places. Therefore, Dali is very clear about this matter.
"If that's the case, then it's really feasible, but the cost of this glass house is not low. If it covers an area of several acres, how much glass will be used? It's not cheap." You Fu frowned and thought, he didn't doubt the truth of Luo Chong, but was considering whether it was worth it to do so. Building a glass house, is it just a one-time use and then thrown away?
“The cost doesn’t matter. No matter how expensive it is, as long as the rice transplanter can be finalized and popularized before the beginning of next spring, then the cost is not considered high and we can get our money’s worth immediately.
“And even if the experiment fails or is completed, this greenhouse will not be wasted. We can grow vegetables in it during the winter. If we sell the fresh vegetables on the street, we can get our money’s worth in one season at most. The cost of a glass house is nothing.” "After hearing this, Luo Chong immediately explained it to them.
After hearing this, several people nodded repeatedly. Yes, it can be used even after the experiment is over. If fresh vegetables can be grown in winter, the people will definitely buy them. Although the price is relatively expensive, they are only sold during the New Year. No matter how expensive it is, they will be willing to pay for it. What's more, the people in the old eight counties of the Han tribe are all very wealthy, and they have a lot of savings at home.
So, the matter of building a glass greenhouse was finalized by several people, and then another situation arose. Lu Guangzhu and She Xin actually quarreled over where to build this greenhouse. Both of them wanted to bring this greenhouse under their jurisdiction.
Apart from anything else, if they get it to their own county, at least it will be convenient to eat vegetables in winter in the future.
"Okay, don't argue. Build one in each of Liuyang County and Weishan County. There are many paddy fields in Weishan County. Lu Guangzhu, you find a suitable place in the official fields of Weishan County to build a greenhouse. There will also be a paddy field structure in it, which is specially used for rice transplanting experiments.
"She Xin, build one in your Liuyang County, and make a dry field to cultivate the potatoes brought back from this trip. Those potatoes are afraid of waterlogging. Remember to find a slightly drier and higher place, and choose a place in the official fields of Liuyang County." Luo Chong waved his hand to stop their quarrel, and then arranged for the two.
The two were overjoyed to hear this, and they all bowed their hands and agreed. But She Xin asked another question.
"Chief, how to build this greenhouse, how big should it be?"
Luo Chong really didn't know how the glass greenhouse was heated. Anyway, it was impossible to bury the heating pipes underground, otherwise the soil would be too hot, and nothing could be grown. Although he had never studied glass greenhouses, Luo Chong had visited the plastic greenhouses in the countryside. That was when the school organized a visit during the agricultural training in junior high school.
The construction of plastic greenhouses is much simpler and has a lower cost than glass greenhouses. Greenhouses in the north are generally facing south, with a mud wall or brick wall on the north side, and then some bamboo poles are bent from the top of the wall and inserted to the south side, and finally covered with plastic film. The heat is generally provided by the north wall. The specific method is to build a stove next to the wall, or simply build a fire wall.
In addition, there must be ear chambers at both ends of the greenhouse to isolate it from the outside world. The ear chambers are like buffer rooms to prevent direct entry from the outside world into the greenhouse, which is conducive to heat preservation and will not let in wind.
As for the size, it really doesn't need to be too big. The larger the area, the larger the space, which is not conducive to heating and heat preservation of the greenhouse. So Luo Chong thought about it and decided to build a glass house in the way of plastic greenhouses.
"The area of a greenhouse is calculated as ten meters by twenty-four meters. The standard of a greenhouse is two acres, with the length from east to west and the width from north to south.
"In our Han tribe, one acre of land is six hundred square meters, which is six meters by ten meters. The width of our greenhouse is ten meters, in order to leave one meter of open space on each side. One reason is that the place close to the glass will definitely be cold, and the other is to leave space for walking. The remaining two meters will leave a road in the middle, and then make two water channels, so that the total width is exactly ten meters.
"One acre of land is ten meters long, two acres are twenty meters, and a greenhouse is twenty-four meters long. The purpose is to leave edges and roads. In addition to the windows, the greenhouse must have two doorways, one on the east and west ends. An ear chamber must be built outside the doorway to make two doors, and the two doors must not be opened at the same time when entering and exiting to prevent heat loss and cold wind from entering.
"Then there is the structure and construction method. A wall must be built on the north side of the greenhouse. Either a brick wall or an adobe wall will do. Then make the wall hollow. A stove must be built on the outside of the wall every five meters. A greenhouse has four stoves, and a fire wall is used to heat the greenhouse. The north wall must be four meters high.
"Then, the south wall is not built with bricks, but with wood or square steel pipes as columns, and a row of two-meter-high columns is inserted. Then, diagonal beams are pulled from these columns, and they are directly placed from the columns of the south wall to the top of the north wall. Finally, glass is inlaid on top. As for how big the gap between the columns and the diagonal beams is, it mainly depends on how wide the glass is.
"To put it simply, this is a house with a single-slope roof. Only one north wall is a brick wall. The east, west, south walls, and the roof are all made of glass curtain walls. Do you understand what I mean?"
