AI Technical Summary
Traditional grain conveyors have fixed discharge ports on their unloading hoppers, making it impossible to flexibly adjust the discharge angle, resulting in inconvenience and low efficiency.
Design a swing mechanism for the discharge port of a grain conveyor's unloading cylinder. Through the combination of a hydraulic cylinder, bearings, and a screw shaft, the angle of the discharge port can be flexibly adjusted. The mechanism includes a hinged connection between an upper movable cover and a lower movable cover. The swing of the discharge port is achieved by using the hinge between the hydraulic cylinder, the unloading cylinder, and the lower movable cover.
The discharge port angle can be adjusted without moving the entire machine, improving efficiency. It has a simple structure and is easy to use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain conveying machine technology, and in particular to a swing mechanism for the discharge port of a grain conveying machine's unloading cylinder. Background Technology
[0002] A grain conveyor is a specialized transport machine that moves agricultural materials such as fertilizers, grains, or seeds from fields or warehouses to other locations. The grain conveyor uses a discharge hopper containing a screw conveyor mechanism to discharge the material in the carriage from the discharge port to other locations. Traditional grain conveyors usually have fixed discharge ports, which cannot adjust the discharge angle. It is usually necessary to move the entire machine to adjust the discharge position, which is time-consuming and labor-intensive and has certain limitations in use. Therefore, a swing mechanism for the discharge port of a grain conveyor is proposed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a swing mechanism for the discharge port of a grain conveyor's unloading cylinder, which can facilitate the adjustment of the discharge port angle and improve efficiency.
[0004] The technical solution of this utility model is implemented as follows: A swing mechanism for the discharge port of a grain conveyor includes a grain discharge cylinder, an upper movable cover, a lower movable cover, a hydraulic cylinder, a bearing, and a screw shaft. The screw shaft is installed inside the grain discharge cylinder through the bearing and is coaxially fitted with the grain discharge cylinder to form the grain discharge cylinder assembly. The fifth shaft hole of the upper movable cover is hinged to the first shaft hole of the grain discharge cylinder, and the third shaft hole of the lower movable cover is hinged to the second shaft hole of the grain discharge cylinder. The chute of the lower movable cover is aligned with the fourth shaft hole of the upper movable cover and is slidably connected by a pin. The two ends of the hydraulic cylinder are respectively hinged to the cylinder bottom pin of the grain discharge cylinder and the cylinder rod pin of the lower movable cover.
[0005] The advantages of this invention are: the discharge angle of the discharge port can be adjusted without moving the entire machine, the structure is simple and the use is convenient. Attached Figure Description
