Abstract

The invention discloses a self-disturbance type soybean precision seed sowing device. A seed box is arranged on the outer surface of a front shell and communicates with the front shell, a rear shell is provided with a seed sowing opening, and a disturbance fan blade is fixed through a shaft and is limited by the inner surface of the front shell and a seed sowing wheel; the disturbance fan blade works to drive a population to move violently, so that population activeness is improved, interspecific friction force is reduced, and the seed filling effect is improved; compound type holes are uniformly distributed on the surface of the inner wall of the circumference of the seed sowing wheel, 20 compound type holes are arranged in each row, the compound type hole structure is provided with guide grooves, a seed fixing plate and an arc-shaped seed cavity, and each guide groove extends to the opening of the next type hole; just one seed can be reserved in the arc-shaped seed cavity to effectively isolate to-be-thrown seeds from other seeds, so that reliable seed cleaning is ensured; the seed fixing plate plays a role in stabilizing the seeds to be thrown, so that the throwing row spacing is consistent. The disturbance fan blade is cooperated with the compound type holes, so that the seed sowing device can complete four working processes of active continuous seed filling, quantitative seed cleaning, stable seed protection and precise seed throwing, and the seed sowing precision is improved.

Description

technical field [0001] The invention relates to a seed metering device for a soybean planter, in particular to a self-disturbance type precise metering device for soybeans, which belongs to the field of agricultural machinery. [0002] technical background [0003] The seed meter is the core working part of the sowing machinery, and its performance directly affects the sowing quality. At present, the research on soybean seed metering device mainly focuses on the optimization and improvement of the seed metering device structure. The influence of the population disturbance in the seed metering device cavity on the filling performance and the research on the mechanism of seed movement are still unclear, resulting in the seed filling of the seed metering device. 1. The clearing process has certain unreliability. For this reason, the present invention designs a kind of seed metering device with disturbing fan blades that can actively destroy the arching phenomenon, adopts the co...
