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.

Problems solved by technology

[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 , 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 the harvesting of grains is completed, farmers need to screen the grains with full grains from the harvested grains as seeds for the next year, and the conventional screening method is to use traditional sieves to screen manually, which has a large workload and low efficiency

[0004] In the Chinese patent with the patent number CN103978999A, a grain drying field paving vehicle is disclosed, which solves the problems of cumbersome paving process, low paving efficiency and high labor intensity in the existing grain paving technology, but it still exists The following technical questions:

[0005] The above-mentioned grain drying field flattening and seed selection vehicle cannot screen the grains while flattening the grains, and screen out grains with full grains as seeds for the coming year
