Spreading and seed selecting vehicle for grain sunning ground

Abstract

The invention discloses a flattening seed selection vehicle for a grain drying field. The flattened grain in the flattening bin is evenly flattened to the drying field by a flattening plate in a flattening seed selection mechanism, and the flattened grain is flattened by a retrieving mechanism. Pick a part of the grain and send it to the seed selection bin, and then use the seed selection board to screen out the full-grained grains in the grains as seeds, which realizes the automatic and uniform spreading of the grains and the simultaneous selection of high-quality seeds, and in the process of spreading the grains, spreading The flat panel also screens out impurities such as clods, stones, straw, and grain husks in the grain, which greatly reduces the labor intensity of farmers and improves work efficiency.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a special vehicle used for grain flattening and grain selection in grain drying yards. Background technique

[0002] After the grain is harvested, in order to prevent the grain from becoming moldy during storage and stacking, it is necessary to spread the freshly harvested grain on the drying yard for drying. Under the existing technical conditions, the spreading of the grain is usually carried out manually; however However, when the grain is paved manually, it is necessary to manually pour, level, and divide the ditch, which leads to cumbersome paving procedures, low paving efficiency, and high labor intensity.

[0003] Moreover, after harvesting the grains, farmers need to screen out the grains with full grains from the harvested grains as seeds for the next year. The conventional screening method is to use traditional sieves to screen manually, which has a large...
