Deep scarification combined land preparation machine and operation method

Abstract

The invention discloses a deep scarification combined land preparation machine and an operation method. The deep scarification combined land preparation machine comprises a traction frame, a tooth frame beam, a deep scarification tooth assembly, a harrow group and a pressing roller, wherein the traction frame is connected with the tooth frame beam, the deep scarification tooth assembly is hung at the lower end of the tooth frame beam, the harrow group comprises a harrow group cross beam and harrow pieces, the pressing roller comprises a pressing roller cross beam and a pressing roller body hung at the lower end of the pressing roller cross beam, the harrow group is located at the front end of the pressing roller body, and the harrow group cross beam and the pressing roller cross beam are connected with the tooth frame beam through the same depth-limiting leveling mechanism. The operation depth of the deep scarification tooth assembly and the operation depth of the harrow group can be synchronously adjusted, and on the basis that the operation depth of the deep scarification tooth assembly and the operation depth of the harrow group are synchronously adjusted, the operation depth of the harrow group can be further independently adjusted.

Description

technical field [0001] The invention relates to an agricultural soil preparation machine tool, in particular to a subsoiling combined soil preparation machine and an operation method. Background technique [0002] The structure of the soil is composed of organic layer, topsoil layer, core soil layer, weathered parent layer and bedrock layer, and the organic layer and topsoil layer are what we often call the farming layer, rich in a large amount of organic matter, microorganisms, earthworms, etc. Provide sufficient air, water, and nutrients for the growth of plants, and at the same time adjust the acid-base properties of the soil. A healthy, stable and reasonable soil structure can maintain the stability of its own ecosystem for a long time, which is a powerful guarantee for increasing production and efficiency. [0003] Compared with the traditional plowing operation, the protective tillage method combining crushing and subsoiling is more conducive to the breeding of earthw...

AI Technical Summary

Problems solved by technology

[0005] The combined subsoiling machine includes a rack beam at the front end, a subsoiling tooth assembly suspended on the rack beam, and a rake group and a pressure roller, and the rake group is located at the rear end of the subsoiling tooth assembly. The pressure roller is located at the rear end of the rake group; during the operation of the subsoiling combined soil preparation machine, after adjusting the working depth of the subsoiling tooth assembly, it is necessary to adjust the depth of the rake group accordingly, which makes the adjustment operation cumbersome
