Abstract

A herringbone rice interline weeding assembly belongs to agricultural machinery; the device comprises a hexagonal driving shaft, a mounting shaft sleeve, a star-shaped cutter holder frame, two right-angle L-shaped weeding cutters and a driving shaft, wherein the mounting shaft sleeve is circumferentially and radially positioned and axially and adjustably moved on the hexagonal driving shaft; the assembly has the advantages of reasonable and simple structure, low manufacturing cost, large weeding area, small weeding area leakage, high weeding rate and high operation efficiency, is beneficial to the discharge of harmful gas in soil and the increase of oxygen content, promotes the improvement of soil quality, and improves the yield and the quality of rice.

Description

Herringbone rice interline weeding assembly

Technical Field

The utility model belongs to agricultural machine mainly relates to a rice terrace rice interline weeding assembly.

Background

With the expansion of the planting area of green organic rice in China and the reduction of the application of chemical herbicides, the application of mechanical weeding operation machines between rice fields is increasing day by day. At present, the existing mechanical rice inter-row weeder in China mostly adopts a comb-tooth type weeding part, and has a plurality of technical problems of large missed weeding area, low weeding rate, small disturbance amount to paddy field soil, being not beneficial to discharge of harmful gases such as methane and the like in the paddy field soil and increase of oxygen content in the soil and the like.

Disclosure of Invention

The utility model discloses an aim at exactly to the problem that above-mentioned prior art exists, combine the actual demand that the operation of weeding between the rice row was used, the herringbone rice inter-row weeding assembly of a new construction of research design reaches that the inter-row weeding is comprehensive, the area of leaking out is little, weeding rate and operating efficiency are high, be favorable to paddy field soil to contain the increase of oxygen content and harmful gas exhaust purpose.

The purpose of the utility model is realized like this: the device comprises a hexagonal driving shaft, a mounting shaft sleeve, a star-shaped knife seat frame, three groups of two right-angle L-shaped weeding knives, a driving shaft and a driving shaft, wherein the mounting shaft sleeve is positioned on the hexagonal driving shaft in the circumferential direction and the radial direction and can be adjusted and moved in the axial direction; the outer end part of the right-angle L-shaped weeding knife is bent, so that a herringbone rice inter-row weeding assembly is formed.

The utility model discloses a structure of two right angle L shape weeding sword symmetry installations, not only the paddy field weeding area is big, and it is few to leak the area, increases the disturbance volume to paddy field intertidal soil moreover, is favorable to the discharge of harmful gas (marsh gas etc.) in the paddy field soil and oxygen content's increase, has rational in infrastructure, simple, low in manufacturing cost is honest and clean, weeding rate and operating efficiency are high, promote the soil quality to improve, improve the characteristics of rice output and quality.

Drawings

FIG. 1 is a schematic view of the structure of a herringbone rice row-to-row weeding assembly.

Description of part numbers in the figures:

1. hexagonal drive shaft, 2, axle sleeve, 3, star knife rest frame, 4, right angle L shape weeding sword.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A herringbone rice interline weeding assembly is characterized in that an installation shaft sleeve 2 which is circumferentially and radially positioned and axially adjustable and movable is arranged on a hexagonal driving shaft 1, a star-shaped cutter holder frame 3 is fixedly arranged on the shaft sleeve 2, and three groups of two right-angle L-shaped weeding cutters 4 are symmetrically arranged on the outer end part of the star-shaped cutter holder frame 3; the outer end part of the right-angle L-shaped weeding knife 4 is bent.

When the weeding machine is used for operation, the output rotary power drives three groups of two right-angle L-shaped weeding cutters 4 which are symmetrically arranged to rotate through the hexagonal driving shaft 1, the shaft sleeve 2 and the star-shaped cutter holder frame 3 in sequence, the full-width weeding is carried out on the surface layer of paddy soil within the width between rows of rice, and the overturning and stirring disturbance operation on the paddy soil layer between rows of rice is completed by utilizing the bending shape of the outer end part of each right-angle L-shaped weeding cutter 4, so that harmful gas such as methane in the paddy soil is discharged, and meanwhile, oxygen is sucked into the paddy soil, and the effect of improving the soil quality is achieved.

Claims
