Abstract

The invention belongs to the field of seeding machines in agricultural machinery, and aims to provide a centrifugal centralized type rape precise seed metering device. The centrifugal centralized type rape precise seed metering device has the beneficial effects that seeds are supplied by one seed box in a centralized manner, the effect that one seeding metering device can meter a plurality of rows of seeds can be realized by means of a centrifugal force, the structure is simple, and the seeds are not damaged; and the seed output is uniform, and the seed output quantity is adjustable, so that the agricultural demands of rape planting in different areas can be satisfied. Meanwhile, different crop seeds can be seeded through replacing and configuring an outer taper cylinder with different seed output structural forms, and different numbers of rows can be seeded through configuring different numbers of seed output tubes. The centrifugal centralized type rape precise seed metering device has the beneficial effects that the seeding efficiency is improved, the whole structure of the seeding machine is simplified, and the universality of the seeding machine is improved.

Description

technical field [0001] The invention relates to the technical field of seeders in agricultural machinery, in particular to a centrifugal collection and row type precision seed metering device for rape. Background technique [0002] Rapeseed is the world's largest oilseed crop, and my country's rapeseed planting area and total output both rank first in the world. However, due to the small size of rapeseed, light weight, high oil content, and easy damage, the mechanized sowing of rapeseed has been greatly restricted for a long time. The seed metering device is the core working part of the seeder, and the seeding quality of the seed metering device is directly related to the quality of sowing. According to the working principle, the rapeseed metering device can be divided into two types: mechanical type and pneumatic type. The mechanical seed metering device has a simple structure and low cost, but usually the operating speed is low and it is easy to cause rapeseed damage and...
