Description

Technical Field

[0001] The utility model relates to the technical field of ditching for yam planting, in particular to a rotary tiller with an anti-winding function. Background Art

[0002] Rotary tillers are tilling machines that work with tractors to complete ploughing and harrowing operations. They are widely used because of their strong soil crushing ability and flat surface after ploughing. They can also cut up the root stubble buried below the surface, making it easier for the seeder to operate and providing a good seed bed for later sowing.

[0003] At present, the existing rotary tillers are prone to weeds or vines getting entangled with the rollers inside the device when performing operations such as crushing soil in wasteland or new land. This can easily cause the entangled vines to reduce the rotation speed of the rollers, thereby reducing the efficiency of the device during use. When excessive entanglement occurs, the device is prone to jamming and other hazards, affecting the service life of the device. Utility Model Content
