Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a grain harvesting device. Background Technology

[0002] Grain, as an indispensable food for human survival, is an extremely important resource in every country. After harvesting, grain is usually dried to remove excess moisture before collection, packaging, and storage. If large areas of grain being dried are not collected in time, sudden drops in nighttime temperatures or the presence of dew and rainy weather can prolong the drying period, leading to mold and spoilage in some grain. Therefore, publication number CN108263267A, entitled "A Vehicle for Collecting and Transporting Grain from Drying Grounds Requires the Use of a Grain Collection Device," discloses "a vehicle for transporting dried grain, in which a rotating brush pushes the grain into a conveyor auger guard plate, and the rotating auger transports the grain into the lifting auger guard plate on the right end of the conveyor auger guard plate." However, grain collection relies solely on the rotating brush, resulting in low collection efficiency. Furthermore, when grain is piled up, the rotating brush cannot reach into the piled grain, only collecting the flattened grain, limiting its application scope.

[0003] Therefore, there is an urgent need for a grain collection device that can collect grain under different conditions. Utility Model Content
