Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillers, and more specifically to an automatic leveling rotary tiller. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, facilitating the operation of the seeder and providing a good seed bed for later sowing.

[0003] The shortcomings of the existing technology: due to the uneven surface of farmland, the left and right wheels of the tractor do not move on the same horizontal plane during field work, causing the rotary tiller connected through the tractor's three-point suspension mechanism to tilt as the tractor tilts. The tilting operation of the rotary tiller not only destroys the hard bottom layer of the farmland, but also affects the rotary tillage performance indicators such as the flatness and tillage depth of the rotary tiller after plowing, resulting in poor rotary tillage effect and low operation efficiency; the automatic leveling system of the rotary tiller is usually based on inclination sensor sensing control, but when encountering potholes and uneven conditions, the inclination sensor may not be able to respond promptly and quickly, and the rotary tiller lacks a structure to provide support on both sides, which may cause the two ends of the rotary tiller to have excessive contact with the ground, thereby affecting the overall forward movement process of the rotary tiller. For this reason, we propose an automatic leveling rotary tiller to solve the above problems. Utility Model Content
