Description

Ultra-deep rotary tillage cutter for agricultural plant protection based on soil disturbance Technical Field The utility model belongs to the technical field of agricultural machinery, and particularly relates to an ultra-deep rotary tillage cutter for agricultural plant protection based on soil disturbance. Background The existing agricultural machinery mostly uses fuel oil as power, has large energy consumption and high cost, causes great pollution to the environment, and is not suitable for agricultural operation in southern hilly areas. The industry pain points are concentrated on the problems of low intelligent level, serious environmental pollution, inadaptability of large-scale machines to small-scale and complex terrain operations, and the like. The development of miniaturized, green and intelligent agricultural robots is an urgent need of the industry, which is not only a technical innovation, but also a deep innovation of the traditional agricultural operation mode. In particular to the soil cultivation field, the traditional rotary tillage tools have some remarkable problems in practical use: Traditional rotary tillage equipment often causes great soil disturbance when the operation, destroys soil structure, influences crop root system and develops, and is difficult to finely divide surface soil effectively, is unfavorable for improving soil gas permeability and water retention capacity. Because the design is unreasonable, traditional rotary tillage equipment needs to consume a large amount of energy in the course of working, has increased agricultural manufacturing cost. Therefore, we provide an ultra-deep rotary tillage cutter for agricultural plant protection based on soil disturbance, which is used for solving the problems in the prior art. Disclosure of utility model In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model discloses an ultra-deep rotary tillage cutter for agricultural plant protection based on soil disturbance, which comprises a central shaft, a plurality of rotary tillage teeth distributed around the central shaft and connecting pieces used for fixing the rotary tillage teeth and the central shaft, wherein the central shaft is of a hollow structure, one end of the central shaft is provided with a coupling interface, the other end of the central shaft is connected with a power transmission device through a bearing, the tail end of a main body of the rotary tillage teeth is fixed in the connecting pieces in a bolt connection mode, the other end of the main body of the rotary tillage teeth forms a cutting edge surface, the rotary tillage teeth are spirally arranged along the central shaft, a specific interval is kept between every two adjacent rotary tillage teeth, the connecting pieces are uniformly distributed on the periphery of the central shaft, and holes used for installing bolts are formed in each connecting piece so that the rotary tillage teeth can be fixed.
