Rape-wheat seeding machine

Abstract

The invention belongs to the technical field of seeding machines in agricultural machinery, in particular to a rape-wheat seeding machine, which is characterized by comprising a land wheel profiling drive unit, a positive-negative pressure unit, a fertilizer discharging unit, a transition shaft unit, a wheat seed discharging unit, a main frame, an auxiliary frame, a positive-negative pressure combination type rape seed precision metering device, a central gearbox, a rotary tillage unit, a profiling compaction unit, a furrowing combination, a furrow forming combination, a furrowing, fertilizing and seeding unit, and a covering unit. The rape-wheat seeding machine is capable of operating once to complete procedures of belt rotary tillage, stubble cleaning, furrowing (bed furrows and seed furrows), land preparation, fertilizing, sowing seeds (rape or wheat), covering with earth, profiling and compacting and the like. The rape-wheat seeding machine is simple in structure, low in power consumption and low interference on soil, can be used for precision seeding of rape and row planting of wheat, and is low in re-seeding rate and sowing missing rate, and high in seeding quality.

Description

technical field [0001] The invention belongs to the technical field of seeders in agricultural machinery, in particular to an oil-wheat dual-purpose seeder used in conjunction with a wheeled tractor, and focuses on solving the problem of joint seeding of rapeseed or wheat with mixed application of seed and fertilizer. Background technique [0002] At present, domestic dryland wheat mechanized sowing technology has matured, and wheat seeding machines in dryland areas have been widely used. However, the existing wheat planters in dry areas, when there is a large amount of straw coverage in the dry land, are especially suitable for rice-oil rotation cropping and rice-wheat rotation cropping under the main planting systems in the southern region and the middle and lower reaches of the Yangtze River. When the sowing performance is poor, it is easy to cause blockage, and the surface quality after sowing is poor, the work efficiency is low, and the energy consumption increases. Th...

AI Technical Summary

Problems solved by technology

[0005] The invention is aimed at wheat seeding, and can complete rotary tillage, stubble removal, furrow and seed furrow opening, fertilization, sowing, soil covering, imitation suppression and other operating procedures in one operation, and overcomes the disadvantages of wheat seeders in dry areas to the southern region and the middle and lower reaches of the Yangtze River. When working in rice fields with stubble in the area, the sowing performance is poor, and it is easy to cause blockage, and the surface quality after sowing is poor, the work efficiency is low, and the energy consumption is high.
