Problems solved by technology

However, due to the deficiencies and defects in the structural design, the straw burying operation assembly on the current model can not reach the standard of no-tillage operation and land preparation for the straw burying rate and burying depth of the returning field. It cannot adapt to the requirements of low-tillage or no-tillage sowing operations, which restricts and affects the popularization and application of straw returning agronomic technology

Embodiment Construction

[0013] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A spring-tooth-type straw burying operation assembly for field returning. On the assembly shaft 1, N spring teeth 2 are evenly arranged in a double-headed helical arrangement along the axial direction. The spring teeth 2 are composed of a fixed section 4 It is connected with the buried operation section 3. The fixed section 4 is in the shape of an arc surface as a whole, and the radius size of the inner surface of the arc surface matches the radius size of the outer surface of the assembly shaft 1. The overall embedded operation section 3 It is involute surface shape, and the cross-section of the buried operation section 3 is rectangular.

[0014] During operation, the actively rotating assembly shaft 1 drives the spring tooth 2 to rotate, and the spring tooth 2 presses the returning straw into the soil after rotary tillage and crushing to complete the b...

Abstract

The invention discloses an elastic-tooth returning-straw burying operation assembly, and belongs to agricultural machines. N elastic teeth arranged in double-end helical line shapes are evenly installed on an assembly shaft in the axial direction, the elastic teeth are formed by connecting fixing installing sections and burying operation sections, the fixing installing sections are in arc-surfaceshapes as a whole, radiuses of the inner surfaces of the arc surfaces of the fixing installing sections are matched with the radius of the outer surface of the assembly shaft, the burying operation sections are in involute surface shapes as a whole, and the cross sections of the burying operation sections are rectangular. The elastic-tooth returning-straw burying operation assembly is novel in structure, reasonable and simple; the burying rate of returning straw is high, the burying depth is large, stress of the assembly is balanced during operation, running is stable, and the land surface issmooth and clean after operation.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation assembly for burying and returning field straw. Background technique [0002] Crop straw crushing and returning to the field is one of the powerful measures to fertilize soil fertility, restore soil aggregate structure, increase soil organic matter content and reduce environmental pollution caused by straw burning. For this reason, straw returning machines of various structures have been developed in recent years, and have been put on trial in agricultural production operations, which has played a positive role in promoting straw returning to the field. However, due to the deficiencies and defects in structural design, the straw burying operation assembly on the current model cannot meet the standards of no-tillage land preparation for the straw burying rate and burying depth of the returned field, and the land after plowing It cannot adapt to the requirements of less-...
