Description

TECHNICAL FIELD

[0001] The utility model relates to the field of harvesting machinery, especially to a conveying and collecting device of crop harvesting system. BACKGROUND

[0002] The existing crop harvesting system usually uses an elevator to convey the grain, so that the grain enters the grain collecting box from the bottom for storage. Since the grain collecting box needs to be arranged above the elevator, and due to the overall layout requirements of various machines in the harvesting system, the position of the existing elevator extending into the grain collecting box is away from the center area of the grain collecting box and close to the side wall, and it is difficult to adjust the relative position of the elevator and the grain collecting box. Therefore, when the grain is sent out from the top end of the elevator, the falling position will also be close to one side of the grain collecting box, resulting in uneven distribution of the grain in the grain box. Moreover, since the elevator is located inside the grain collecting box, the grain outlet of the elevator will not be higher than the top surface of the grain collecting box. During the continuous grain conveying process, the area near the elevator will be filled to the top side of the grain box first. At this time, if the grain continues to be conveyed, the grain will be pushed by the grain inside the elevator to move the grain accumulated near the elevator to the remaining space of the grain box. Therefore, the existing grain collecting device not only easily causes uneven distribution of the grain in the grain box, but also easily causes accumulation and blockage due to uneven distribution of the grain, affecting the conveying and storage of the grain.
