Reciprocating motion extrusion type strip seedbed construction unit

Abstract

The invention discloses a reciprocating motion extrusion type strip type seedbed construction unit, and belongs to agricultural machinery. According to the reciprocating motion extrusion type strip type seedbed construction unit, hanging arms are symmetrically arranged on a connecting frame at intervals, the hanging arm is provided with a smashing and cutting device for strip seedbed soil, straw and stubble smashing and an operation auxiliary device, the smashing and cutting device for the strip seedbed soil, the straw and the stubble is composed of an end face cam A, a sawtooth disc coulter, a spring seat A, a chain wheel A, a cutter shaft, an ejector rod A, a pressure spring A and a plane thrust bearing A, the operation auxiliary device is composed of an end face gear B, a depth-limiting anti-skid straw pressing wheel, a spring seat B, a chain wheel B, a wheel shaft, an ejector rod B, a pressure spring B and a plane thrust bearing B, a chain is sleeved on the chain wheel A and the chain wheel B; according to a single body of the reciprocating motion extrusion type strip type seedbed construction unit, the strip seedbed soil and the stubbles are cut up through rotation and axial reciprocating motion of the sawtooth disc coulter, meanwhile, the strip seedbed soil is extruded, smashed, gathered and gathered inwards in the opposite direction, the single body has the characteristics of unique and reasonable structure, low power consumption, good constructed strip seedbed quality and high operation efficiency.

Description

Technical field [0001] The present invention creates an agricultural machinery, mainly involving a working monomer suitable for the construction of a cultivation pattern for the strip bed. Background technique [0002] Belt Bed Construction is a reasonable loose pattern of soil and straw roots in the cultivated layer of unmatched land to obtain a strip-striring pattern suitable for the sowing of sowing operations, and its work components take a bed The quality and efficiency of builds are crucial. At present, the presence of the current strip-based bed construction device is mainly in the active rotation structure, and the high-speed rotating spiral tool is loose, and there is a large power consumption and serious mechanical vibration. The soil is thrown out of the belt parts, the quality of the bib is poor; in addition, the passive plowed strip bed construction device uses two fixed-folded disc plows structures, when work, Two disc pingers are pulled by passive rotation under so...

AI Technical Summary

Problems solved by technology

At present, the currently used strip seed bed construction device is mainly based on the active rotating structure. During operation, the high-speed rotating rotary tiller cutter cuts and loosens the soil and straw stubble at the seed bed, resulting in large power consumption and serious machine vibration. 1. The technical problem that the seed bed soil is thrown out is much loss in the strip and the quality of the seed bed is poor; in addition, the passive plowing type strip seed bed construction device adopts the structure of installing two fixed and opposite disc coulters. During operation, The two disc coulters are passively rotated under the action of soil resistance, and the soil on the inner side of the two disc coulters is loosened in strips. It is found in the production and use practice that the disturbance and fragmentation of the seedbed soil by this structural device The capacity and the ability to chop the root stubble are obviously insufficient, the quality of the strip seed bed is poor, and the operating depth is unstable, which cannot meet the technical requirements of mechanical sowing for the strip seed bed
