Six-head spiral rotary tillage and stubble burying knife roller

Abstract

The invention relates to a six-head spiral rotary tillage, stubble removal, stubble burying knife roller, which solves the problems of low crushing rate and burying rate and high operation power consumption existing in the existing knife roller. The technical solution includes a cutter shaft and multiple groups of rotary tiller blades arranged on the cutter shaft along the axial direction, and a secondary cutter group with equal sliding cutting angle is arranged between the two adjacent groups of rotary cultivating blades; The angle-cutting secondary cutter group is composed of two equal-sliding-angle-cutting secondary cutters radially arranged around the knife axis, and the included angle between two adjacent equal-sliding-angle secondary cutting knives is 180°; The rotary tiller group is composed of four rotary tiller blades radially arranged around the knife shaft, and two adjacent rotary tiller knives rotate in opposite directions with an included angle of 90°. The invention has simple structure, stable operation, is suitable for paddy field and dry land operation, improves straw crushing rate and burying rate, reduces operating power consumption, and is not easy to entangle grass.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a six-head spiral rotary tiller, stubble removal, stubble removal and grass burying knife roller. Background technique [0002] As an important part of conservation tillage, straw crushing and returning to the field can effectively solve the problem of environmental pollution caused by straw burning, and it can also play a role in water retention, soil moisture conservation, promotion of microbial activities, and reduction of chemical fertilizer usage. The straw crushing and returning machine is one of the main machines for straw crushing and returning to the field. The structure and design parameters of the cutter roller have a direct impact on the operation performance and effect of the whole machine. [0003] The traditional rotary cultivator cutter rolls include left and right cutter rolls, which are output to the left and right cutter rolls after the tractor outputs power to the ge...

AI Technical Summary

Problems solved by technology

In response to this problem, technicians have carried out various researches. For example, the application number is 201410436141.8, which discloses a combined straw returning rotary blade roller. The straw crushing rate, burying rate, and grass entanglement problem are also greatly reduced, but in actual operation, it is also found that due to the existence of the grass burying knife, the power consumption of the tractor is relatively large, especially in the case of dry operation, the power consumption of the operation is significantly increased.
