Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a high-strength depth-adjustable rotary tiller frame. 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] In a rotary tiller, a steering reducer is needed to reduce the power. In the existing rotary tiller frame structure, the steering reducer is fixed to the frame through a mounting seat, and the mounting seat is often welded to the inner side of the frame of the frame. The mounting seat and the frame are in the same horizontal plane, which makes the depth of rotary tillage relatively limited. In addition, the connecting seat connecting the rotary tiller frame and the tractor often does not have the function of adjusting the rotary tillage depth, resulting in a small scope of application of the rotary tiller.
