Problems solved by technology

When carrying out subsoiling operations in straw-covered land, due to the large amount of straw, it is easy to wrap around the subsoiling working parts, resulting in straw blockage
Among the subsoilers developed in my country at present, there is no subsoiler that can effectively solve the problem of straw clogging.

Embodiment Construction

[0014] The invention aims at the deficiencies in the prior art, and provides a side machete subsoiler with small tillage resistance, small surface disturbance, high straw processing capacity, adjustable loosening depth and range, and smooth ground surface after operation. It is composed of frame, side curved subsoiling knife, depth control wheel and grass cutting disc. The grass-cutting disc 5 and the side-curved sub-loosening knife 1 appear in groups, and are respectively fixed on the crossbeam 9 of the frame 7 by the fixing device 6 and the fastening device 2, and the grass-cutting disc 5 is located on the side-curved sub-loosening knife 1 Straight ahead, the subsoiling knives 1 bent left and right are equal in number and installed symmetrically; the ground wheel 3 is fixed on the crossbeam 9 by the anchor 8 . The support rod 4 is fixed on the two side beams of the beam 9 of the frame 7 (as shown in Fig. 1 and Fig. 2 ). The above-mentioned side bending deep loosening knife ...

Abstract

A deep soil loosener with laterally bent blades is composed of machine frame, laterally bent deep loosening blades with 40-50 deg of inclination and parabolic shape, ground wheels, and grass cutting disks. One grass cutting disk is matched with one latterally bent deep loosening blade and is arranged in the front of said loosensing blade for preventing the straw or grass from winding on the loosening blade. Its advantages are low interference to cultivated soil layer and smooth ground surface.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a side machete subsoiler used in conjunction with a tractor. Background technique [0002] The farmland soil will be over-compacted due to the trampling of humans and animals and the walking of agricultural machinery; for the plots that have been plowed all the year round, a hard and dense plow layer is formed at the bottom of the plow layer. Soil compaction and plow bottom cause soil pores to decrease, which affects soil water permeability and air permeability, and affects the development of crop root systems and the absorption and utilization of crop soil water, resulting in crop yield reduction, drought resistance, soil erosion, and soil degradation. And other issues. Soil subsoiling is one of the important farmland mechanization operations, which can break the bottom of the plow, eliminate the compaction effect of the soil, and improve the structure and moistu...
