Subsoiling rotary tillage combined soil preparation machine

Abstract

The invention relates to a subsoiling rotary tillage combined soil preparation machine, which belongs to the technical field of agriculture machinery subsoiling soil preparation and aims at solving the technical problems to provide the subsoiling rotary tillage combined soil preparation machine with the advantages that the structure is simple, the operation quality is high, and the cost is low. The subsoiling rotary tillage combined soil preparation machine adopts the technical scheme that a steering transmission box is arranged in the middle above a machine frame, the two ends of an output shaft of the transmission box are respectively connected with one end of a rotary tillage cutter shaft, the two rotary tillage cutter shafts are in linear horizontal arrangement, in addition, the other ends of the two rotary tillage cutter shafts are respectively and movably arranged at two sides of the machine frame through bearings, a plurality of rotary tillage cutters are respectively arranged on each rotary tillage cutter shaft, in addition, a front chiseling type subsoiling shovel is arranged on a front beam of the machine frame, two ground wheels are arranged at the front end of the machine frame and are respectively positioned at the two sides of the front chiseling type subsoiling shovel, a plurality of back chiseling type subsoiling shovels are arranged at the back part of the machine frame, the back end of the machine fame is provided with a grinding plate, the lower end of the grinding plate is connected with the back end of the machine frame through a plurality of pressure springs, and an included angle is formed between the grinding plate and the pressure springs. The subsoiling rotary tillage combined soil preparation machine is mainly used for the subsoiling soil preparation before the seeding.

Description

technical field [0001] The invention relates to a subsoiling and rotary tillage combined soil preparation machine, which belongs to the technical field of agricultural machinery subsoiling and soil preparation. Background technique [0002] At present, agricultural conservation tillage technology is the most advanced sustainable agricultural technology in the world today, and it is an agricultural cost-saving, efficiency-enhancing and environmental-friendly technology that is promoted and applied nationwide. Its main technical features: subsoiling the land instead of plowing the land, shallow plowing and no-tillage sowing, and the coverage rate of straw residues on the surface after sowing crops is greater than 30%. However, with the existing subsoiler, after the subsoiling operation, there is a subsoiling ditch, and the ground surface is uneven, and it is necessary to carry out another rotary tillage land preparation operation, which has many operating procedures and high p...

AI Technical Summary

Problems solved by technology

These two forms of combined subsoiler and rotary tillage machine are simply combined subsoiler and rotary tiller. The structure is larger in size, heavier in weight, higher in price, greater in operation resistance, and higher in fuel consumption. The operation on the surface covered by straw crushing is prone to clogging, and it is impossible to work on the surface without straw crushing. The adaptability of the machinery and tools is not strong, and the market development prospect is not optimistic.
