Self-disturbance small-particle-size dual-purpose mechanical and pneumatic combined type collecting and discharging device

Abstract

The invention discloses a self-disturbance small-particle-size dual-purpose mechanical and pneumatic combined type collecting and discharging device which comprises a seed box, a seed storage chamber, a seed unloading and collecting groove, a shaped hole wheel and a fan seed falling opening. The type hole wheel comprises a seed metering shaft and N type hole wheel single bodies which are mounted on the seed metering shaft along the axial direction of the seed metering shaft; a circle of sinking grooves are evenly distributed in each hole wheel single body in the circumferential direction, a hole is formed in the middle of each sinking groove, and a boss is formed between every two adjacent sinking grooves. The inclined parabolic holes and the boss seed disturbing structure are integrated in the hole wheel single body, compared with a seed disturbing-free device or an independent seed disturbing device, population disturbance can be increased, seed filling performance can be improved, and meanwhile the overall structure of the seed-metering device is simplified.

Description

technical field [0001] The invention relates to the technical field of seeding in agricultural machinery, in particular to a self-disturbing small particle size combined mechanical-pneumatic combined collector. Background technique [0002] Rapeseed is the main source of vegetable oil and feed protein in my country. Sesame and cabbage are important characteristic oil crops and daily vegetables, with wide planting range and large scale. The average particle size of rapeseed, sesame and pakchoi is less than 3mm, which is a small particle size seed. Because of its small particle size, large difference in shape, easy damage, and difficulty in mechanized sowing, the planting method is still mainly manual sowing. As of 2020, rapeseed machine The sowing rate is 35.65%, and the comprehensive mechanization rate of vegetables is less than 40%, so there is an urgent need for sowing machinery. Manual sowing is labor-intensive, low in efficiency, and poor in sowing quality, making it di...

Problems solved by technology

Manual sowing is labor-intensive, low-efficiency, and poor-quality sowing, making it difficult to achieve standardized and large-scale planting

There are many kinds of seeds with small particle size and great difference in material properties, so it is difficult to use both seed metering devices; seeds with low sphericity and poor fluidity are easy to arch in the seed box, and the seed introduction process is easy to stay in the seed introduction tube, which reduces the efficiency of the seed metering device. Seed filling and seed guiding performance: Insufficient combined use, unstable seed filling, and poor seed guiding are important factors that limit the utilization rate of small-size seed metering devices and the further improvement of seeding quality
