Special aerial seeding device for oilseed rapes

Abstract

The invention belongs to the technical field of oil crop planting, and particularly relates to a special oilseed rape aerial seeding device which comprises a flying mechanism, L-shaped plates are longitudinally and fixedly arranged at the lower end of the flying mechanism, a rapeseed containing box is fixedly arranged between the two L-shaped plates through a fixing mechanism, and a discharging hopper is fixedly arranged on the lower side wall of the rapeseed containing box. A discharging pipe is fixedly arranged on the lower side wall of the discharging hopper, a discharging speed adjusting mechanism is arranged in the discharging pipe, symmetrical seeding pipes are fixedly arranged on the side wall of the discharging pipe, symmetrical rotating pipes are arranged at the lower ends of the two seeding pipes in a sleeving manner, annular grooves are formed in the pipe walls of the two seeding pipes, and the rotating pipes are arranged in the annular grooves. Symmetrical limiting blocks are fixedly arranged on the inner walls of the two rotating pipes, so that the discharging speed can be conveniently adjusted according to the soil condition and the sowing season, the sowing density of the rapeseeds is controlled, and the later growth of the rapeseeds is more convenient.

Description

technical field [0001] The invention relates to the technical field of planting oil crops, in particular to a special aerial seeding device for rape. Background technique [0002] Rapeseed is one of the main oil crops in my country. The content of rapeseed is 35%-50%. The tender stems and leaves of rapeseed are edible. It is an important economic crop in my country, with a planting area of ​​about 100 million mu. The traditional planting method of rapeseed is to use manual sowing, but manual sowing is only suitable for small-scale planting. In large-scale planting, in order to effectively improve planting efficiency, aerial sowing devices are often used for sowing. [0003] However, when the existing aerial seeding device is used for sowing rape, it is inconvenient to adjust the feeding rate of rapeseed, so that when sowing, the planting density cannot be controlled according to soil conditions or planting time. All of them affect the normal growth of rapeseed. SUMMARY OF...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special aerial sowing device for rapeseed, to solve the problem that the existing aerial sowing device proposed in the above background technology is inconvenient to adjust the feeding rate of rapeseed when sowing rapeseed, which leads to the inability to adjust according to the soil when sowing. Depending on the situation or planting time to control the planting density, resulting in the problem that too much or too little rapeseed will affect the normal growth of rapeseed
