Deep-scarification rotary tillage combined soil preparation machine

Abstract

The invention discloses a deep-scarification rotary tillage combined soil preparation machine, and belongs to the field of agricultural machines. The deep-scarification rotary tillage combined soil preparation machine comprises a rotary tillage cutter assembly, a deep-scarification shovel and a crushing roller, which are arranged on a frame; the crushing roller comprises outer crushing teeth whichare staggered and welded on an surface of a cylindrical drum, and the crushing roller has a self-cleaning structure: the cylindrical drum of the crushing roller is a hollow structural drum, and innercrushing teeth are staggered and welded onto the interior of the hollow structural drum; a self-excited vibration mechanism is arranged between the deep-scarification shovel and the frame, and includes a deep-scarification shovel fixing beam, a frame fixing beam, a frame fixing vertical beam and a straight-stroke elastic telescopic device; the deep-scarification shovel fixing beam is fixed at theupper end of the deep-scarification shovel, the frame fixing beam is fixed at the lower end of the frame, and the upper end of the frame fixing vertical beam is fixed at the front end of the frame fixing beam; the lower end of the frame fixing vertical beam is hinged to the front end of the deep-scarification shovel fixing beam; and the straight-stroke elastic telescopic device and the frame fixing vertical beam are arranged in a front-back corresponding manner. The service life is prolonged, the working quality is improved, and the working resistance is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery. Background technique [0002] Many areas in my country have used rotary tillers for shallow plowing and rotary tillage operations year after year, resulting in the formation of a hard, closed plow bottom layer between the plow layer and the core soil layer. The existence of the plow bottom layer affects the downward extension of the crop root system, poor ventilation and water permeability, and affects the transfer of nutrients and water from the inner soil layer to the crop root system, thereby affecting crop yield. One of the solutions is subsoiling. During the subsoiling operation, the subsoiling shovel tears, squeezes and disturbs the soil, thereby breaking the bottom of the plow, improving the structure of the soil, enhancing the ability of the soil to store water, retain moisture, and resist drought and waterlogging, thereby increasing crop yields. However, there are two major proble...

AI Technical Summary

Problems solved by technology

However, there are two major problems with the subsoiling machine: one is that the operation resistance is large, the operation is blocked, and the ground surface is uneven after operation; The roller teeth work normally, reducing the effect of crushing soil

At the same time, rotary tillage operation is required after a single subsoiling operation, and the tractor's multiple entry work will easily cause secondary compaction of the soil and reduce work efficiency
