Anti-slope spoon type corn precision seed metering device and seed metering method thereof

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to an anti-slope spoon type corn precision seed metering device and a seed metering method thereof. A seed metering shell (1) is provided with a square plate (15), an adjusting plate (11) and a seed metering opening (13); a cover plate (2) of the seed metering device is provided with a seed feed opening (21), a seed discharge opening (26), guiding grooves (24), two first convex grooves (25) and a second convex groove (22); a plurality of circular holes (35) are uniformly distributed at intervals in the periphery direction of the outer edge of a seed metering plate (3), a spherical surface shaped spoon body is connected to the surface of each circular hole (35), and semi-closed spaces formed by the spherical surface shaped spoon bodies and a partition board (4) next to the seed metering plate (3) are called seed holding spoons (31); and a plurality of smooth tooth-shaped bulges (61) are distributed in the periphery direction of the outer edge of the top of a circular ring of a rotating wheel (6). According to the anti-slope spoon type corn precision seed metering device and the seed metering method thereof disclosed by the invention, the influence of slope on seed metering properties can be reduced, and besides, the situation that seeds are cracked is effectively avoided; redundant seeds can be well removed, so that the seed metering device has good single-grain properties; and the seed holding space is enlarged, and the seed feeding properties are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a seed metering device, in particular to an anti-tilt spoon type corn precision seed metering device and a seed metering method thereof. Background technique [0002] 90% of the land in Southwest my country is distributed in hilly mountains and plateaus. Although this area is one of the dominant areas for corn planting in my country, due to the limitation of special terrain, the development of corn mechanized sowing technology is slow. [0003] The seed meter is the core component of the seeder. The spoon-wheel seed metering device is the most common mechanical precision seed metering device in China at present. There are several small spoons evenly distributed on the seed metering plate. When the seed spoon rotates upwards, the excess seeds slide down by their own weight, and the seeds are cleared by themselves, and then the seeds fall into the seed guide wheel, and...

AI Technical Summary

Problems solved by technology

The terrain in hilly and mountainous areas is complex and the slope is large. When the seed meter is vibrating or tilted, the seeds in the small spoon can easily fall into the seed filling area, and cannot smoothly fall into the seed guide impeller, resulting in missed sowing.
