Chapter 996 Test Drive
Huh————
The chimney erected high on the side of the tractor suddenly blew out a puff of black smoke. The powerful force of the steam engine drove several plunger pumps to rotate rapidly, and the tractor rushed out. Everyone
present hurriedly made way for a road, and at the same time they were very excited. This car can really move! ! ! The steam engine on the front of the car spewed out the exhaust gas and water vapor after the burning of coal. The huge tractor also drove out slowly and powerfully under the control of Luo Chong. As soon as it left the factory, a cold wind blew in the face in the middle of winter. At this time, Luo Chong suddenly wanted to curse. He should have built a shed and a glass windshield for the cab first. Driving a tractor outdoors in the winter is really unbearable. Behind the tractor, everyone in the factory ran out. Luo Chong drove the car to the door and stopped, turned his head and asked Lin Fei who was following the car. "What are we going to test today?" "Chief, we're going to test the obstacle crossing ability, the traction ability, and the driving experience of this car to see if there are any modifications that need to be made." Lin Fei shouted while standing aside. Because it was windy outside, he couldn't hear clearly without shouting. Luo Chong nodded, tucked his neck into the collar of his coat, and said casually, "Then let's test the driving and obstacle crossing first." After that, he began to head to the dedicated road in the test area under the command of the researchers. The grassland and hilly landforms here in Xingang County have many undulating earthen mounds. Although part of them were flattened by the Han tribe because of the construction of the city and the construction of the road, most of the remaining areas are still in their original ecological state. This is probably because the people in Xingang County never cultivate the land, and there are no fields here. All the people in Xingang County are either in the mines or in the factories, so there are still large areas outside the city that can be used to test vehicles. The researchers selected a special test site outside. Coming out of the factory workshop, on the way to the test site, there are wooden poles inserted along the way as markers, which are very eye-catching on the snow-covered snow. Luo Chong sat in the driver's seat and pushed the joystick that controlled the speed of the four wheels forward to the end, so that the tractor maintained the maximum output power, and then concentrated on manipulating the steering rod in his arms to control the left and right. Lin Fei and other researchers and Luo Chong's guards all followed on horseback. As they rode wildly to follow the tractor, they kept looking at it and discussing it, with fiery eyes. "Chief, the raised anti-skid pattern on the tire is so useful. It doesn't slip at all when walking in the snow." Lin Fei rode his horse to the side of the tractor and shouted to Luo Chong. Luo Chong smiled and didn't say anything. That's it? This is called anti-skid? It's just snow, not ice. If you want to talk about anti-skid on snow, what can compare to the anti-skid ability of the track. Everyone followed closely behind, and came to the test site surrounded by ropes amid the roar of the tractor. After reaching the destination, Luo Chong slowed down and stopped. The researchers next to him immediately began to give orders. While listening to their introduction, Luo Chong looked at the complex site in front of him. This site has a special terrain formed naturally, and of course there are many artificial arrangements. For example, the high and low slopes are demarcated according to the natural terrain, and the more complex tunnels, forests, and swamps are artificially created according to the terrain. The high and low slopes are not difficult, just a few consecutive climbs and uphills. Although the snow on the ground makes climbing difficult, this tractor with huge torque did not disappoint everyone. Luo Chong personally drove it over several slopes in succession, one steeper than the other, and finally passed them successfully without any danger. Next is a tunnel at one end. The so-called tunnel does not refer to a tunnel, but a dirt road with many large pits dug. In some places, there are pits on the right side, while the left side is much higher. In some places, it is just the opposite. It is rugged and uneven, and the layout is random. Luo Chong was not careless in dealing with this section of the tunnel. He was not driving fast. The tractor under him tilted back and forth under his control, sometimes high and sometimes low. Sometimes the front of the vehicle and the parking space were even twisted in the opposite direction to an exaggerated angle, but it had no effect on driving. Driving skills on such a road section have little effect on it. It depends entirely on the tractor's four-wheel independent suspension system to force through. The excellent passing performance of the vehicle is clearly displayed in this tunnel. Just after passing the tunnel, after turning a corner, there is a lane with more complicated road conditions, the "mountain forest logging site". This site not only has a slope, but also many standing wooden stakes, simulating trees in the forest. The gap in the middle is narrow and can only accommodate a tractor, but this time it is necessary to test the driver's skills more. If this is not enough, there are actually some logs placed horizontally on the road of this "logging site". If you want to pass, you can only press over the logs in front of you, but there are also some diagonally placed logs and wooden stakes in front of you blocking the front, and you also need to climb over the obstacles one by one. Luo Chong sighed in his heart, this is too crazy, but fortunately he is now driving a large-sized, high-chassis tractor, and its off-road performance is not inferior to any modified off-road luxury car. After all, when it comes to real off-road, what car can compare with a tractor? Luo Chong drove over fearlessly, relying on his skilled driving experience in his previous life to climb over obstacles one after another. Although he had not driven this kind of tractor controlled by a joystick in his previous life, he had driven off-road vehicles, such as Hummer, Warrior, Land Cruiser, Ford pickup truck, and although he did not own such vehicles, he drove them a lot. Although those cars are controlled by steering wheels, the driving experience and experience are the same, all with four wheels, and there is not much difference. After a few minutes of climbing over this forest obstacle section, a river ditch, or ditch, appeared in front. Tractors are destined to work in farmland. Since they are going to farmland, they naturally have to climb over ditches, so this is also a must-test item. The size of the ditch was dug exactly in accordance with the size of the farmland irrigation ditches commonly seen in the Han tribes, but such a ditch was not difficult at all in front of the huge wheels with a diameter of 1.6 to 2 meters, and was easily turned over.
After crossing the ditch, we came to the last section of the muddy road.
This artificially created muddy road section is mainly used to test whether the tractor can enter the paddy field. If it can enter the paddy field, then everyone can find a way to build a rice transplanter, and then use mechanical transplanting instead of manual transplanting. If it works, then the Han tribe can use these huge agricultural machinery to open up thousands of hectares of fertile land on the vast plains near the capital, and harvest countless rice without using much manpower. In this way, the Han tribe will no longer have to worry about hunger. Even if there is any disaster, the Han tribe can rely on the huge storage to survive.
Luo Chong drove this huge tractor to the muddy road and finally hesitated. He really had no confidence in such a terrain. It was not that the tractor's horsepower was not enough, nor was it a bad mechanical design, but that this tractor was too big and heavy. It was normal for it to be trapped by its own weight in such a soft land.
However, in order to test the real performance of the vehicle, he still pushed the joystick and arched into the mud. The tractor puffed black smoke and white mist and slowly walked into the mud. Luo Chong watched the wheels sink into the mud, but they didn't sink too deep, not even covering the rubber tires. Although the mud had a great adhesion to the tires, they still moved slowly and effortlessly under the powerful torque of the plunger pump. The researchers around
could n't help cheering at the scene in front of them, but Luo Chong frowned, thinking something was wrong. The rice fields need to be covered with a layer of water for a long time. Different water levels are required at different stages according to the growth cycle. For example, when transplanting rice, the water should be neither too deep nor too shallow. A depth of three centimeters is enough, that is, when the palm is placed flat on the soil, the water in the field just covers the back of the hand. When heading and filling, the amount of water should be increased to allow the rice grains to absorb enough water. But in general, the entire rice planting cycle, except for the last ten days of drying and drying the land before harvesting, is basically muddy at other times. It is hard to imagine how soft the land covered by water for such a long time can be. However, the muddy road in front of us is a winter muddy road. There is hard frozen soil underneath. Who knows whether water can penetrate it? Therefore, winter testing of the muddy road section has no reference value at all. After figuring this out, Luo Chong is no longer entangled. The finalization of a car must be accompanied by a lot of tests. It is wishful thinking to get everything done through one test. Finally, after passing all the test sections, Luo Chong controlled the joystick to stop the tractor at the end of the site, and then said to the people who came running. "The frozen soil in winter is too hard. The test of the muddy road section does not count this time. After the ice and snow melt in spring, you have to conduct experiments again." Lin Fei was stunned when he heard this, but after thinking of Luo Chong's famous saying, "Bold hypothesis, cautious verification", he immediately nodded to express his attitude. What is cautious verification? To put it bluntly, the experimental environment this time is not up to standard, so do more experiments next time. "Okay, I'll take note of this. This is pending. We'll test it again next year. Chief, please tell us about the driving experience. When crossing various obstacles, are there any control systems that need to be improved? Can you give us some advice?" Lin Fei nodded and immediately began to ask Luo Chong about the driving experience. Driving experience is also part of this test, but it will not be tested separately. Instead, it will be integrated into various road tests. Only the feeling when passing through various road conditions is the most important driving experience. Otherwise, if you only drive on flat ground, what is there to talk about in driving experience? Anyway, you just drive it, and there is no experience at all. It's like a sports car, which can only reflect its ability and value when drifting. Everyone lit a bonfire in the straw shed to keep warm, and refilled the tractor with coal and water. After a rest, they continued to test. The tractor's complex road passing performance has been tested. Except for the unsatisfactory results of the muddy terrain, the others are qualified. Then the next test is the most important drag test. To the south of the site, there is a fairly flat piece of land where everyone is going to attach agricultural machinery to the tractor to test the effect on the spot. The agricultural machinery that needs to be tested has already been delivered by horse-drawn carriage. At present, there are not many agricultural machinery developed by the Han tribe. The main research and development direction is still mainly ploughing, fertilizing, and sowing. As for more complex harvesters, there are none yet. In line with the idea of starting with the easy and then the difficult, everyone first attached a rotary tiller to the tractor. This rotary tiller uses a five-point bracket, which is controlled by a reserved hydraulic rod to take off and lower, and outputs power to the rotary tiller through the drive shaft. The rotary tiller is a thick steel pipe, and many blades for turning the soil are welded on the outer surface of the steel pipe. It looks like a huge mace that is turned horizontally. This mace is placed on the bracket of the rotary tiller and then hung on the tail of the tractor. When using it, the operator only needs to control the hydraulic lever to lower the "mace", let the blade on it insert into the soil, and then start the horsepower to drive the huge "mace" to rotate in the soil through the steam engine main engine and the transmission shaft, so that the land behind it can be turned over. Luo Chong climbed onto the cab of the tractor again. The rear wheel diameter of this tractor is two meters, and the body is even taller. If the roof of the cab is added in the future, it will be conservatively estimated to be about three and a half meters, and the width of the vehicle is also nearly three meters. For such a huge tractor, the rotary tiller mounted on the back will naturally not be much smaller. The "mace" behind it has a working width of six meters, which can be called a giant among agricultural machinery. Even among modern advanced agricultural machinery, it can still rank in the forefront. Pushing the handle, Luo Chong controlled the tractor to the end of the test field. He looked back and consciously aimed at the position. Then he stepped on the lever to control the extension of the hydraulic rod at the rear of the vehicle, and then lowered the rotary tiller until he felt the huge resistance from the vehicle body. From these feedbacks, he could feel whether the "mace" had been put to the bottom. When the hydraulic rod reached the bottom and could not go down any further, he released the handle that controlled the hydraulic rod, then stepped on the clutch again, controlled the gear separation, and then switched the power system. The huge power of the steam main engine acted on the wheels and the main drive shaft again, and the "mace" behind him immediately started to rotate. Woo woo woo woo———— wheezing wheezing———— The vehicle body forced the steam engine to provide more powerful power output because of the force. The chimney spewed out puffs of black smoke, and the exhaust valve on the cylinder also wheezed and spewed out white mist. The powerful torque drove the vehicle body and the rotary tiller behind it to move forward bravely. Luo Chong drove the world's first steam tractor straight forward. The "mace" behind him was like a giant beast with iron teeth and steel fangs. The frozen soil under his feet was vulnerable to these steel teeth and was eaten up by the mace in an instant.
