Positive and negative pressure combined type rape seed precision combined direct seeding machine

Abstract

The present invention belongs to the technical field of planters, in particular to a positive-negative air-pressure combinational-typed rapeseed precision combined direct-planter, which is characterized in that a stander is provided with a positive-negative air-pressure combinational-typed seeding apparatus and a positive-negative air-pressure working unit, wherein, the positive-negative working unit consists of a positive-negative air compressor, a power transmission apparatus and a supporting bracket; the supporting bracket is welded on the stander; a main beam, a middle beam and a rear beam of the stander are integrated to be a whole through a side plate and an auxiliary side plate; a gear box is fixed at the middle of the main beam; an upper suspension arm and a lower suspension arm are hanging on three points on the main beam; a seed-bed rotary-cultivation unit is arranged right below the main beam; a rotary-cultivation straight blade and a rotary-cultivation rocked blade are fixed and welded to a rotary-cultivation blade seat on a rotary-cultivation shaft; the seeding apparatus is arranged between the middle beam and the rear beam at intervals. The planter has the advantagesthat the damage of the soil is small, the repeating-planting and the planting-leakage rates are low and no seed is damaged, which can realize the fertilization application and precision plantation and greatly reduce the thinning and final singling work in the late growth management period of the rape.

Description

technical field [0001] The invention relates to the technical field of seeding machines in agricultural machinery, in particular to a combined positive and negative air pressure rapeseed precision combined direct seeding machine, focusing on solving the problem of rapeseed precision 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...

Problems solved by technology

[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 meter itself will squeeze the rapeseed during the working process and cause damage. The damaged rapeseeds will condense into balls and easily block the socket, resulting in missed seeding. The later stage seedlings and seedlings will require a lot of labor, which is difficult to achieve. Precision sowing; there is another kind of seeder that can realize precision sowing, which is to put the special paper rope that has been placed indoors with precision sowing equipment into the rapeseed according to the plant spacing into the soil according to the agronomic requirements. The operation process is cumbersome and the cost of sowing higher
