Pneumatic centralized conveying type seed distribution system based on electrostatic attraction and seed separation operation method

Abstract

The invention provides a pneumatic centralized conveying type seed distribution system based on electrostatic attraction and a seed separation operation method. The seed separation operation method comprises the steps that the seeding rate and the seed feeding force of each row are detected in real time; the seed distribution system is adjusted in real time; the seeding consistency of each row is improved; the seeding rate is accurately controlled; and then the seeding quality is improved. The pneumatic centralized conveying type seed distribution system based on the electrostatic attraction comprises a rack, a seed box, a seed separation device, a seed metering device and a pneumatic centralized conveying device, the seed metering device comprises a seed metering wheel, a seed metering motor and a seed metering box, the seed metering box is located below a seed falling opening, the seed metering wheel is located in the seed metering box, and the seed metering wheel is driven by the seed metering motor; the pneumatic centralized conveying device comprises a fan and a conveying pipe; the seed separation device comprises a seed separator, a bulge is arranged at the top end of an inner cavity of the seed separator, and a plurality of seed guide pipes are connected below the seed separator; a seed separation quantity adjusting device comprises electrostatic generators and gravitation plates, the gravitation plates are positioned in the conveying pipe close to the upper end, and the electrostatic generators are arranged outside the gravitation plates.

Description

technical field [0001] The invention relates to a pneumatic concentrated conveying type seed distribution system, in particular to a pneumatic concentrated conveying type seed distribution system and a sorting operation method based on electrostatic gravity, which is suitable for use in pneumatic concentrated conveying type seeding machines. Background technique [0002] Crop sowing operations are divided into two methods: single-grain precision sowing and drill sowing. Conventional wheat, quinoa, field greens and other small-sized crops are sown mainly by drill sowing and broadcasting. The sowing operation requires the most advanced grain drill machinery in the world. The consistency of seed volume is an important index to evaluate the quality of the seeder operation. The better the consistency, the more uniform the sowing, the better the crop growth in the later period, and the higher the farmland yield. Due to the influence of different seed varieties, sizes, quality, vi...

AI Technical Summary

Problems solved by technology

Due to the influence of different seed varieties, sizes, quality, vibration of the whole machine, conveying air pressure, etc., and the corners of the conveying pipe are likely to cause seeds to gather, the control of the seeding rate and the uniform seeding effect of the conventional pneumatic centralized conveying method are not ideal. Quantitative consistency is poor
