Grain unloading device and wheat harvester with same

Abstract

The invention discloses a grain unloading device and a wheat harvester with the same. The grain unloading device comprises a grain unloading barrel and a grain unloading groove, a sealing cover is arranged at a position of a grain unloading opening of the grain unloading barrel, an upper end of the sealing cover is hinged to the grain unloading barrel, a first elastic part is disposed between the sealing cover and the grain unloading barrel, the first elastic part exerts an acting force on the sealing cover to enable the sealing cover to rotate in a direction back on to the grain unloading barrel, a locking mechanism is arranged below the grain unloading barrel, the locking mechanism comprises a lever-type pressing piece which is hinged to a rotating shaft, an upturning locking edge is arranged at a right end of the pressing piece, a second elastic part is arranged between the pressing piece and the grain unloading barrel, the second elastic part exerts an upward acting force on the right end of the pressing piece, an unlocking pressing structure is arranged in the grain unloading groove, when the grain unloading groove moves to a grain unloading position, the unlocking pressing structure exerts an upward acting force on a left end of the pressing piece, a locking pressed structure is mounted on the right end face of the sealing cover, and when the grain unloading groove moves to a grain storage position, the locking pressed structure is matched with the inner side surface of the groove bottom of the grain unloading groove in an abutting mode. The synchronous opening and closing of the sealing cover can be correspondingly achieved only by controlling the turning of the grain unloading groove, and the operation is simple.

Description

technical field [0001] The invention relates to a wheat harvester and a grain unloading device applied to the wheat harvester. Background technique [0002] Wheat harvesters are generally equipped with a granary to store wheat. Due to the limited storage space of the granary, after a certain amount of harvesting operations, it is necessary to carry out unloading operations to discharge the wheat from the granary. The unloading operation depends on the grain unloading device. . The grain unloading device of the traditional wheat harvester includes a grain unloading barrel, which is connected with the granary. There is also a grain unloading trough hinged on the granary. The rotation axis of the grain unloading trough is perpendicular to the axis of the grain unloading cylinder. The grain storage position when the discharge port is vertically upward, and the other working position is the grain unloading position when the discharge port is inclined downward. When unloading g...

AI Technical Summary

Problems solved by technology

For the grain unloading device of this structure, no matter whether the grain unloading trough is turned over to the unloading position or the grain storage position, the opening and closing of the insert plate must be manually operated accordingly. The operation of the car will undoubtedly increase the labor intensity of the driver.
