The working principle of the multi-functional micro tillage machine is as follows: The micro tillage machine applies a number of technologies in the design and manufacturing, such as track tension adjustment, linear travel control technology, hydraulic lifting and control technology, and variable speed control linkage. With interlocking control technology, zy12 machine tool quick hooking technology, etc. The crawler chassis of Zhongyun's multi-functional micro-tiller has an annular circulating crawler track wrapped around the outside of the driving wheel and a series of rollers, so that the wheel does not directly contact the ground, but acts on the ground through the circulating crawler track, and then drives the crawler track through the driving wheel. , while the wheels are relatively rolling on the crawler tracks, the crawler tracks are repeatedly laid forward on the ground, thereby driving the chassis to move.
