Abstract

The invention relates to a pneumatic rape precise combined direct seeder, and belongs to the technical field of seeders. The seeder comprises a frame, a rotary tillage unit, a fertilizer unit, a land-wheel profile device, a sub-frame, a positive / negative air pressure working unit, a positive / negative air pressure combined seed-metering device, a ditching unit and a driven system. The pneumatic rape precise combined direct seeder has the advantages of simple structure, compact layout, low power consumption, little damage on soil, low re-sowing rate and seeding absence rate, and no seed damage,and can realize the combined operation of rotary tillage, stubble cutting, ditching, sowing and fertilization. The pneumatic rape precise sowing can save seeds and greatly reduce the thinning and final singling operation of the later growth management of rape; and the combined operation greatly improves the production efficiency. The seeder is used for precise combined direct seeding of rapeseeds, and also can be used for the precise direct seeding of other small spherical grain-size seeds.

Description

technical field [0001] The invention relates to the technical field of seeding machines in agricultural machinery, in particular to a pneumatic rapeseed precision-quantity combined direct-seeding machine, and focuses on solving the problem of rapeseed precision-quantity combined direct-seeding. Background technique [0002] At present, the domestic rapeseed planting is still dominated by the traditional planting mode of growing seedlings first and then transplanting or artificial slipping, thinning and setting seedlings after sowing, which is labor-intensive and low in production efficiency; mechanized planting is mainly direct seeding, that is, using equipment sockets The seed drill of the wheel type seed meter mixes the rapeseed with chemical fertilizers and sediment or mixes a certain proportion of fried rapeseed in the seed before sowing, so that the seeding amount is relatively large, and the number of effective seeds sown is random, and The vertical socket wheel seed m...
