Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to the technical field of rotary tillage, and specifically refers to a deep tillage grass shredder and a shredder device. Background Art

[0002] A rotary tiller usually uses a crushing device to complete the soil crushing and tilling work. Among them, the rotary tiller in the crushing device is the core working component of the crushing device. The performance and service life of the rotary tiller directly determine the operating effect and efficiency of the rotary tiller.

[0003] However, when the existing rotary tiller is working, the bend at the front end of the rotary tiller is easy to entangle with the weeds growing horizontally during the rotation process. Once the weeds are entangled, the contact area between the rotary tiller and the soil will increase, resulting in increased resistance to the rotary tiller entering the soil, resulting in poor rotary tillage effect;

[0004] In addition, since the front end of the rotary blade is in a bent structure, it is prone to deformation and breakage when it is in contact with the ground, weeds or stones for a long time and encounters excessive resistance, which shortens the service life of the rotary blade. Once the rotary blade is damaged, the working efficiency of the rotary tiller will be reduced and the use cost of the rotary tiller will be increased. Summary of the invention
