[0002] A rotary tiller is a tillage machine that is matched with a tractor to complete tillage and harrowing operations. Because of its strong soil crushing ability and flat surface after tillage, it has been widely used; at the same time, it can cut and crush the stubble buried below the ground surface, which is convenient for the operation of a seeder and provides a good seedbed for later sowing.

[0003] During the use of the side plow of a rotary tiller, it is necessary to adjust the furrow width according to the planting requirements of different crops. Most of the existing structures of the side plows of rotary tillers are fixedly arranged, resulting in a fixed furrow width. When it is necessary to adjust the furrow width, generally, the entire furrow plow is replaced to adjust the furrow width. The method of replacing the furrow plow not only has a high labor intensity for workers but also has a low work efficiency. To solve the above problems, a side plow structure of a rotary tiller is proposed. Content of the Utility Model
