A spiral cutting type seed tape cleaning device

Abstract

The invention belongs to the technical field of agricultural machinery, and in particular relates to a spiral cutting type seed belt cleaning device, comprising: a driving knife shaft 1, a stubble cutting disc 2 and a right-handed cutting disc symmetrically installed on both sides of the stubble cutting disc 2 Dividing knife group 3 and left-handed cutting knife group 4; The stubble cutting disc 2, right-handed cutting knife group 3 and left-handed cutting knife group 4 are cut into the soil to cut off the straw and divide the straw to both sides. A clean work belt is formed in the front; the stubble cutting disk 2, the right-handed cutting knife group 3 and the left-handed cutting knife group 4 are all fixedly installed on the active knife shaft 1, and are uniformly arranged within 360° on the circumference of the active knife shaft. Cloth more than 2 groups of right-handed cutting knife group 3 and left-handed cutting knife group 4. The seed belt cleaning device of the present invention can effectively obtain clean seed belts, improve the quality of no-tillage sowing, and is beneficial to crop yield increase, and has less disturbance to the soil, and can effectively separate the straw from the soil, which is beneficial to seed germination and growth .

Description

Technical field[0001]The present invention relates to a helical spiral species cleaning apparatus used in supporting the drill-saving seedr, belonging to the field of agricultural machinery.Background technique[0002]The operation of the exemption-tillage generator is covered by straw, requiring a certain straw cleaning device to provide a cleaning species for subsequent sowing operations. The passive species of the cleaning device requires a certain weight to ensure sufficient slitting power of the claw device, but the weight of the existing existing no-tillage planting machine is difficult to meet the requirements, the species cleaning effect is poor; the active species cleaning The device rotates at high speed under power drive, which can ensure full cutting of straw, but there are still some problems in the domestic active species cleaning device: (1) The cutter is depth, the soil disturbance is large; (2) Different stalk effect Obviously, the straw cannot be cleared in time afte...

AI Technical Summary

Problems solved by technology

The passive seed belt cleaning device requires a certain weight of the machine tool to ensure sufficient stalk cutting power of the stalk cleaning device, but the weight of the existing domestic no-tillage seeders is difficult to meet the requirements, and the seed belt cleaning effect is poor; the active seed belt cleaning The device rotates at a high speed driven by power, which can ensure the full cutting of the straw, but there are still some problems in the domestic active seed belt cleaning device: (1) The depth of the cutting knife is large, and the soil disturbance is large; (2) The effect of separating the stalks is not good. Obviously, after the straw is crushed by the cutter, it cannot be cleared out of the operation line in time, resulting in the mixing of soil and stalks in the operation line, which affects the subsequent sowing operations
