Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural machinery, and more specifically, particularly relates to a rotary tilling blade for a 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. When tilling, the rotary tiller mainly relies on rotary blades to loosen the soil. The rotary tiller blades are usually iron blades. Several blades are installed on the blade shaft. The blades are driven to rotate by driving the blade shaft. During the rotation of the blades, the root stubble buried below the surface can be cut into pieces, which facilitates the operation of the seeder and provides a good seed bed for later sowing.
[0003] Based on the prior art, it is found that the existing rotary tiller blades have some shortcomings. First, there is a lack of structure to enhance the strength of the rotary tiller blades. During the loosening process, if the rotary tiller blades collide with stones, the blades are prone to bend due to the lack of structure to enhance rigidity, making them impossible to use a second time. Secondly, the connection structure between the rotary tiller blades and the drive shaft is imperfect. Since there is a gap between the blades and the drive shaft, the blades are prone to shaking during operation, which will aggravate the wear of the blades and affect their service life. Utility Model Content

First, there is a lack of structure to enhance the strength of the rotary tiller blade. During the loosening process, if it collides with a stone, the blade is prone to bend due to the lack of a structure to enhance the rigidity, and thus cannot be used a second time. Secondly, the connection structure between the rotary tiller blade and the driving blade shaft is imperfect. Since there is easily a gap between the blade and the driving blade shaft, the blade is prone to shaking during operation, which will aggravate the wear of the blade and affect its service life.
