Coarse cereal seeding machine for no-tillage seeding

Abstract

The invention discloses a coarse cereal seeding machine for no-tillage seeding. The coarse cereal seeding machine comprises a rack, a fertilizer apparatus, a seed sowing device, a seed manure box, a stubble breaking and ditching device, a suppression mechanism, ground wheels and transmission mechanisms. The machine adopts a stubble breaking, ditching, seed manure applying and seeding single body, a suppression wheel mechanism single body, a high ground clearance and large spacing transverse beam rack and the various transmission mechanisms for intensively changing speeds so as to realize stubble breaking and ditching, seed manure application, and semi-precision no-tillage seeding of wheat, corns, coarse cereals and small-grain pasture seeds. Particularly, the problems of crop stubble winding and blockage, hilling, mixed seed manure application, difficult burying of the ditching device, much disturbance to a soil layer, unevenness of a soil covered ground surface, large traction resistance and the like in the no-tillage seeding process are solved. The machine is simple in structure and easy to operate, has multiple purposes, is low in manufacturing cost and is suitable for specialized households of planting, and small and medium-sized farms to popularize and apply.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a combined unit used for drought-resistant sowing in dry land for field operations. Background technique [0002] The implementation of conservation tillage can protect farmland, reduce dust, store water and moisture, resist drought and save water, improve soil fertility, increase soil organic matter, promote the utilization of straw returning to the field, reduce greenhouse gas emissions, increase unit yield, reduce costs, and increase income. Efficacy is a revolutionary farming measure that synchronizes economic and ecological benefits and wins both farmers and the country, and has significant economic, ecological and social benefits. The no-tillage seeder, the supporting tool of the conservation tillage method, is the key to the realization of this technology. [0003] The no-tillage seeder is a machine for sowing on uncultivated stubble. The no-tillage seeder has been developed al...

AI Technical Summary

Problems solved by technology

However, the soil ditch opened by it is relatively wide, which inevitably disturbs the soil layer; (2) chisel-shaped tooth or narrow hoe-type ditch opener has a simple structure and good soil penetration performance, but it is easy to block; (3) narrow rotary ripper

It has good soil loosening and crushing performance, but it needs to be driven by the power output shaft, and the structure is complex

Therefore, due to the insufficiency of these main working parts, the current no-tillage seeder cannot directly cut off the stubble of the stalk when it is operating, effectively preventing the stalk from being entangled and blocked by the machine tool, and opening a seed ditch is relatively wide. There are many disturbances in the land, the surface of the soil is uneven, and it is impossible to sow small grass seeds, etc.
