Peanut seed sowing self-disturbance seed discharge disc of suction seed discharge apparatus

Abstract

The invention discloses a peanut seed sowing self-disturbance seed discharge disc of a suction seed discharge apparatus. The peanut seed sowing self-disturbance seed discharge disc comprises a disc. Acentral mounting hole is formed in the center of the disc, a plurality of peanut external contour shape fitting spatial stereoscopic seed filling profiled grooves are peripherally uniformly formed inthe front surface of the disc and are close to the edge of the disc, a ventilation hole which is perforated through the back surface of the disc is formed in each seed filling profiled groove, the seed filling profiled grooves are in spatial irregular shapes sunken towards the disc, and in other words, the edges of the seed filling profiled grooves extend towards the upper end surfaces of the ventilation holes to form spatially irregular cones; seed stirring strips are arranged on the front surface of the disc, and each seed stirring strip is arranged in a region between the two correspondingadjacent seed filling profiled grooves; gear teeth which can mesh with gears of driving mechanisms to implement edge driving running are arranged at the peripheral edge of the disc. The peanut seed sowing self-disturbance seed discharge disc has the advantages that resting peanut seed groups can be disturbed by the peanut seed sowing self-disturbance seed discharge disc in operation procedures, resistance between seeds can be lowered, accordingly, the single seeds can be easily broken away from constraints of the seed groups, and the seed filling performance of the seed discharge apparatus can be effectively improved; collision damage of the seeds can be reduced during high-speed rotation, filling missing can be prevented, and the peanut seed sowing self-disturbance seed discharge disc issuitable for the high-speed peanut seed sowing requirements.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an air-suction seed metering device self-disturbing seed metering plate for peanut sowing. Background technique [0002] At present, due to its high-speed and precise characteristics, the air-suction seed metering device has become the key development direction of precision seeding technology for large seeds. Seed filling is the first link in the working process of the air suction seed metering device, and it is also the basis of the subsequent links. Its working principle is to use the seed disturbing device to disturb the seeds to an orderly boiling state to reduce the inter-species resistance, and then use the airflow to form a pressure difference on both sides of the air holes on the seed tray to adsorb the seeds on the seed tray. The seed disc rotates to break away from the densely accumulated species, and single grains are discharged from the outlet of the seed meter. If this li...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing air-suction precision seed metering device for peanut seeds has short filling time and heavy weight under the condition of high-speed operation, and it is easy to cause the seed hole to be leaked, resulting in missed sowing and damage.
