A grain seeder for no-tillage sowing

Abstract

The invention discloses a miscellaneous grain seeder for no-tillage sowing, which comprises a frame, a fertilizer discharger, a seed metering device, a fertilizer seed box, a stubble breaker and a ditch opener, a suppression mechanism, a ground wheel, a transmission mechanism and the like. This machine adopts stubble breaking, ditching, seeding, fertilization, and seeding, a single pressing wheel mechanism, a high clearance and wide spacing beam frame, and a variety of centralized variable speed transmission mechanisms. It has realized the semi-precision no-tillage sowing of stubble breaking, furrowing, seed fertilizer application, wheat, corn, miscellaneous grains and small pasture seeds. In particular, it solves the problems of entanglement and blockage of crop residues, choked soil, mixed application of seed and fertilizer, difficulty of trench openers entering the soil, frequent disturbance of the soil layer, uneven surface of the covering soil, and large traction resistance during the no-tillage sowing process. The implement is simple in structure, easy to operate, multi-purpose, and low in manufacturing cost, and is suitable for popularization and application by professional planting households and small and medium-sized farms.

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.
