Chapter 9 Chapter 9 Antenna Electric Control Combined Cultivator

Crawler motorcycles are different from ordinary motorcycles. Its movement does not rely on wheels, but on crawlers, just like crawler tractors.But unlike a tractor, a tractor has two crawlers, and it has only one. Therefore, like riding a bicycle with two wheels, you must keep your balance when riding on it.However, the track of the tractor is made of metal, while the track of the motorcycle is made of rubber, which ensures the smooth running of the car, the speed is very fast, and it can go everywhere unimpeded.Tracked motorcycles are capable of traversing the worst surfaces, even places where there is no road at all.

All this is what new friends tell travelers.He was very happy to hear that they were going to Sun City, saying that he lived in Sun City himself, and people called him Bun. Talking with Bun, the travelers rushed to the front of the hill and drove up the mountain.The road up the mountain was very steep, and Xiaohualian sitting behind couldn't sit still.At last he felt himself empty, and cried out: "Hey, hey! Stop it! I'm going to fall!" Before he could finish his words, the person had already fallen.Before reaching the top of the mountain, Xiaoyuan stopped the car and ran to save Hualian.Quanzhi and little pushpin ran after him.Everyone was very happy to see that Xiao Hualian was in good health and not injured.The little bun said: "There is another big advantage of crawler motorcycles. Because there are no wheels and the seat is very low, even if they fall, they will not be as heavy as falling from ordinary motorcycles."

Now our travelers are on high again.They again saw the circles they had observed before. "Ah!" shouted the little thumbtack, and even clapped his hands. "I guessed it right! The circles on the ground—that's where your machines plowed." "Not at all," said the bun firmly. "The black circle you see on the right is the land that has just been overturned, and nothing has grown on it. The place where the sprouts have been spit out, the circle is green. The red circle is the poppy field. The yellow circle is the field of poppies. A dandelion in bloom."

"What about the white circle?" asked the little thumbtack. "The white circle is also a dandelion, but mature and fluffy." "Why do you grow dandelions? Can it be eaten?" Quan Wu asked strangely. "No, of course you can't eat it. However, rubber can be extracted from the dandelion root, the stem can be used to make various plastics and fibers for weaving, and the seeds can also be used to extract oil." "Tell me about it," Xiaohualian asked Bun. "I don't get it a little bit. I know the colored circles are fields, with . "Things that look like little peas are also round to you, but they are farther away from us, so they appear smaller."

"Well, I understand." Xiao Hualian replied. "Farther over there it's all debris: a speckled patch." "This is also a circular land, but it is farther away from us, so it appears smaller." "How many machines do you need to cultivate so much land?" asked the little thumbtack. "Ten." Bun replied. "Ten units?" Quan Zhi was taken aback. "impossible!" "Please believe me." Bun said. "Everything you see around here is plowed by the ten machines I manage." "But there's about a thousand plots of land here!"

"No, it's not a thousand, it's much more. Do the math: a machine can plow a round field in an hour. If it plows ten hours a day, it can plow ten fields. Ten One machine will plow one hundred plots of land in one day. In ten days, it will be ten times more, that is, one thousand. Since we harvest three times a year on average, the plowing period will take nearly one hundred days. The land plowed in one hundred days is Ten times more than ten days of plowing, that is, ten thousand pieces of land." "Ten thousand yuan!" Quan Zhi shouted. "Isn't there more stars in the sky? You did it all by yourself?"

"No, I'm not alone. There are five of us. We work four shifts, and there's always one person off." "It's the same anyway." Quan Zhi waved his hand. "Now you will see even more wonderful machines in operation," replied Bun. The travelers got back on the tracked motorcycles and rushed to the top of the mountain within a minute. Behind the mountain was a wide valley.The colorful circles, pea spots and small spots can no longer be seen on the valley.The entire valley is a huge circle, which starts not far from the foot of the mountain and extends to the edge of the forest in the distance.This circle seems to be made up of rings one by one, just like the Saturn pictured in astronomy books.There is a white circular building in the center surrounded by a wide black circle.Outside the black circle is a golden circle, outside the golden circle is a wider green circle, and outside the green circle is the largest black circle.

"The whole field here is plowed and wheat planted by a radio-controlled tiller," said Bun. "In the spring, it plows the center field around the white building first. Then it gradually plows in circles. Come on. After a few days, the young shoots in the center will turn green, then the wheat will set ears and begin to mature, and the combine machine will continue to plow. At this moment, the combine harvester in the central place has started to work. It is also harvested circle by circle according to the maturity of the wheat. Do you see that circle of black land around the white building? The wheat has been harvested there. The yellow circle is ripening wheat, and the green circle is also wheat, Not ripe yet. The outermost black circle is the land that has just been plowed, and the crops on it have not yet sprouted."

"What's the white building in the center for?" asked the little thumbtack. "Here's the barn and the mill. The grain is dumped in and ground into flour for storage. There's a radio magnet on the roof of the barn. There's a little tower like a lighthouse over there, see?" "Where's the radio-controlled combine cultivator?" asked Clueless. "A radio-controlled tiller. It's on the left side of the field. It's not clear from here. Let's drive closer." Everyone got on the motorcycle again, descended the hill, and galloped along the edge of the plowed land—Chen, stopped next to the combined aircraft.It looks like an armored car with several square funnels on it.The "car" had no doors, windows, or wheels, and was almost half-sinked in the mud.There was a big hole in the front of the car, and a knife beside it chopped up the dirt as the Combine drove forward.Two iron machine shovels are like snowplows, constantly scraping up the chopped soil and grass together, pushing them into the big hole and throwing it away. Above the big hole is written-"radio-controlled combined tillage machine".

"Look carefully." Little White Bread said. "You just see the dirt disappearing into the combined machine and nothing else, right?" "It's not bad at all, we can't see anything else." Xiao Hualian said. "What's going on in the machine?" Bun asked, and then answered himself: "In it the soil is loosened, and the manure and seeds are finely mixed in; The larvae are wiped out." "How did you get rid of it?" Quan Mo asked. "The larvae are destroyed by ultrasonic waves, and the weed seeds just need to be heated and roasted, and then they will not germinate. Now they look at the machine from the back. There is also a big hole there. The loosened soil, as I said before, It was also mixed with seeds and fertilizers, and poured out from the hole. In this way, the land where the Combined Machine walked was overturned, and seeds were also planted. The machine worked day and night—no Day and night, rainy and sunny or cold and hot, the production efficiency is of course very high.”

"So, the operation of this machine is left unattended?" Quan Mo asked. "No, the 'Radio Control Combined Cultivator' also needs to be attended," said Bun. "Please take a look at the spherical mirror mounted on the front. This is the spherical screen of the TV. The screen shows the combine itself and everything that happens around it. The images here are transmitted by the TV to the central station of the radio-controlled combine. Center The driver in the station could see the Union and everything around it on the same TV globe. Using radio signals, he could tell the machine to turn left, turn right, stop, start again, or suddenly need to go around some obstacle. " "Why does the driver sit in the center station? Can't he sit here?" asked the little pushpin. "If the driver only manages one machine, he can also sit here, but he is in charge of sixteen combined machines at the same time. There are sixteen such spherical TVs installed in the central station, and the driver can see the images of sixteen combined machines at the same time. working condition." "Where is the central station?" asked the little thumbtack. "The central station is located on two streets in Sun City." "That's interesting!" Little Pushpin laughed. "So, with this combination machine, you can cultivate land without leaving the city?" "Yes." said Bun. "And you can see that not one, but sixteen combined machines are cultivating on sixteen fields that are far apart from each other." "I really want to know what the driver sees on the spherical screen at the central station." Quan Mo said. "That's exactly as we see it in this spherical mirror. You see, the mirror reflects the machinery in front of the machine, the whole land in front of and around it, the whole sky, and even us all. All of this, The driver can see it from the stand. You see, I will send a signal to the driver to stop the machine." Bun stood in front of the machine and raised his hand.The combined machine stopped immediately, and the motor stopped. At the same time, someone asked loudly, as if the voice came from a barrel: "What's the matter?" "Nothing happened," cried Bun. "We want to check to see if there is anything wrong with the TV." "There's nothing wrong with the TV," the voice answered. "Continue to work!" Bun said and stepped aside.The motor hummed again, and the machine continued to move forward. "That's interesting!" said the little pushpin. "So this machine can not only see, but it can also hear and talk to other people?" "It's not the machine that speaks and obeys, it's the driver." Bun replied. "The machine is equipped with a loudspeaker and a microphone. The signal is transmitted by radio to the station through the microphone, and the station transmits it here. The driver can hear what we say here by turning on the radio communication equipment, and we can hear it through the loudspeaker He said it." "It's not surprising." Xiao Hualian said. "It's kind of like a phone call." "What do these Combines run on? Alcohol? Or perhaps atomic power?" asked Clueless. "It doesn't use alcohol or atomic energy, it uses wireless electromagnetic energy." Bun replied. "What kind of energy is this?" "It's similar to electrical energy, except that electrical energy is transmitted through wires, while wireless electromagnetic energy is transmitted directly through the air." "I have another question," said Quan Mo. "You said the driver saw everything reflected in this mirror at the central station. I was also reflected in it, so he saw me too?" "Of course." Bun replied affirmatively. I didn't know what to think, what would happen if he suddenly stuck out his tongue and showed it to the driver.Anyway, the driver is so far away, so nothing can be done about him.So, Quan Wuzhi approached the spherical mirror, while others were not paying attention, stuck out his tongue and made a grimace. "Huh! Don't be shy, stick out your tongue!" said loudly through the loudspeaker. I don't feel ashamed at all.He giggled to hide his embarrassment, and muttered: "I just want to try the driver, see if he sees me, so he can really see." "You can see it, you can see it, now you don't have to doubt it anymore." Xiao Hualian said. "There is only one problem that I still can't figure out: I know it's a kind of electromagnetic energy, and I know that the machine is controlled remotely. The driver can see and hear whatever he wants. I even know that the soil will loosen in the combined machine. It will be mixed with the seeds, but where do the seeds and fertilizers in the combined machine come from? I can’t figure it out!” "Oh, it's very simple to say." Bun laughed. "Twice a day the trucks bring the seeds and fertilizer here and dump them into the big hole in the top of the combine." "In that case, it's really nothing strange!" Xiao Hualian shouted. "It would be strange if the seeds, instead of being poured into the unit, poured themselves out of it in batches!" The visit to the United Aircraft ends here, and our travelers return.This time, Bun rounded the hill to prevent Xiao Hualian from falling off the motorcycle when going uphill.
