Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery accessories, in particular to a soil loosening and grass chopping deep tillage tool for a micro-tillage machine. Background Art
[0002] A micro-tiller is a small tillage machine powered by a small diesel engine or gasoline engine. It has the characteristics of light weight, small size and simple structure. It is widely used in dry land, paddy fields, orchards in plains, mountainous areas and hills, and can complete a variety of farmland operations. The main working part of the micro-tiller is the deep plowing knife, which can cut, crush and mix the soil evenly.
[0003] Existing deep tillage tools mostly focus on loosening soil rather than providing a strong grass-chopping function. They often use threaded connections for assembly, which makes them susceptible to vibration, high operating forces, and other factors during actual use, leading to thread damage and tool loosening. Furthermore, it is difficult to disassemble and replace aging and damaged tools, seriously impacting their usability. Therefore, to address these technical issues, a deep tillage tool for a micro-tiller with both loosening soil and grass-chopping was developed. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a soil loosening and grass chopping deep tillage tool for a micro-tillage machine to solve the existing problems raised in the above background technology.

[0011] Beneficial effects
[0012] The utility model provides a soil loosening and grass chopping deep tillage tool for a micro-tillage machine. It has the following beneficial effects:
[0013] (1) The soil loosening and grass chopping deep tillage tool for micro-tillers can cut weeds deep in the soil and the grass chopping knife can cut weeds on the surface of the soil through the cooperation between the deep tillage knife and the grass chopping knife. The strong grass chopping function lays a good foundation for the healthy growth of crops. The deep tillage knife and the grass chopping knife are set in an annular staggered manner, and the soil loosening and grass chopping are more uniform without leaving dead corners. Because the socket is under a heavy load during the operation of the tool, it is usually easy to be damaged and deformed. The double connection of the grass chopping knife, the socket and the connecting shaft strengthens the socket and extends the service life of the socket.
[0014] (2) The soil loosening and grass chopping deep tillage tool for a micro-tiller is designed so that the vibration generated by the deep tillage blade during operation is partially absorbed by the buffer pad through the cooperation among the raised portion, the support column, the first connecting plate, the buffer pad and the second connecting plate, thereby reducing the vibration of the socket and further preventing damage to the socket.
