Usually driving into the mud, it is generally difficult to walk, if you drive into a mud pit, the wheels have been spinning is difficult to come out, not to mention the swamp, there is a possibility of sinking in minutes. Russia is sparsely populated, there is almost no human activity in some places, because the harsh environment has created some complex terrain, Siberia and the far north are mostly creeping soil, such as swamps, if people fall down, it is difficult to get out, let alone cars.
But the Russians are known as the fighting people, in order to cope with the swamp, they specially built a machine, this is the Russian special off-road vehicle ZVM-2901, and usually see the off-road vehicle is very different, the shape is very unique, there is no traditional rubber wheels, the following replaced by two long spiral cylinders, can really cross the swamp?
In fact, it was built by the Soviet army in the 1970s, originally used to transport supplies on the swamp, and then it has been abandoned, the Russians have modified and upgraded it, the cab of the truck and the screw drive base fused together, to have the current appearance, 5.5 meters high, weighing 1.5 tons, mainly in the absence of roads and various land, can transport heavy machinery such as excavators, cranes and rescue machines to areas where they cannot enter, Thus launching a rescue operation. It is very powerful, powered by a 159-horsepower engine, with a top speed of 25 kilometers per hour, and can adapt to extreme road conditions, whether it is swamps, mud, sand, or even snow, it can not stop its progress.
The most amazing thing is that this machine can also drive in the water, don't look at the two spiral cylinders so big, in fact, the inside is hollow, can provide enough buoyancy, so that this machine in the water, to achieve the real amphibious, in the forest is also like walking flat, front and back left and right, 360 degrees no dead angle. However, it has a disadvantage, that is, it can not be driven on cement or asphalt roads, if it is on the road, not only is it easy to damage the road surface, but the spiral cylinder will also wear out.
The most critical place of this machine is the two long spiral cylinders at the bottom, rotating under the action of power, the movement of the entire component is the same as the principle behind archimedes' screws, the spiral cylinder will also generate power when rotating, thus pushing the machine forward, but it can not only travel forward, but also turn on its own, even like a crab sideways is not a problem, the worse the road conditions, the greater the forward thrust generated by the spiral, even if it is a swamp, as long as the machine drives all the way over, it is easy to cross, Looking at this driving scene, I sweated for it.
I have to admire the wisdom of the Russians, who have created such an advanced machine, worthy of the fighting nation. I have a bold idea, in many of our places the arable land mainly rely on cattle ploughing, people in the back to drive cattle, cattle in the front to pull the plough, not only the efficiency of the ploughing is slow, but also easy to work, if we introduce this machine, or learn their technology, make a tiller, so that young people can ride it to cultivate the land, so that they like agriculture, no longer have to work in the field, is not the best of both worlds, I am really very smart.
