Abstract

The invention relates to the field of agricultural tools, and especially relates to a tool for an agricultural cultivator. The tool comprises a blade shaft, upper blades, lower blades, and bolts. The upper blades are bent curved blades, and the lower blades have same shapes and structures as the upper blades. A plurality of bolt holes are uniformly provided on the upper blades, and a plurality of bolt holes are provided on the lower blades at places corresponding to the bolt holes on the upper blades. The bolts penetrates the bolt holes, and connect the upper and lower blades, such that blades are formed. The blades are welded on the blade shaft with a welding technology. Bolt holes are provided on the blade shaft. Buffering springs are arranged between the upper and lower blades. Two ends of the buffering springs are respectively fixedly arranged on the upper blades and the lower blades. The tool provided by the invention has the following advantages: the blades are welded on the blade shaft, such that connection is firmer and stabler, and falling is prevented; also, double-layer blade connection is adopted in the blades, such that blade strength is improved; buffering springs are arranged between blades, such that buffering is provided for stresses on the blades, and blade service life is prolonged.

Description

Technical field [0001] The invention relates to the field of agricultural knives, in particular to a knife of an agricultural cultivator. Background technique [0002] With the development of modern agriculture, mechanized operations have been adopted in related operations such as arable land, trenching, soil loosening, planting, and forestry reclamation to improve work efficiency. At present, most cultivators use single-blade knives. The knives are simple in structure. If they are damaged, they need to be replaced completely. The knives and knives cannot be assembled and used, and their versatility is poor. In addition, when encountering hard soil, the knives The hardness is often not up to the requirements, it is easy to damage the tool, increase the economic cost, but also reduce the production efficiency, and it is difficult to achieve the expected result. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a cutter for ...
