Description

Technical Field

[0001] This utility model relates to the field of plant protection vehicle technology, specifically to a rear-end adjustment mechanism for an unmanned plant protection vehicle. Background Technology

[0002] The spraying system installed on the unmanned agricultural vehicle is used for agricultural plant protection and irrigation. This system uses a pump system to deliver water stored in a tank, which is then sprayed through nozzles on the spraying assembly for irrigation. This significantly improves the efficiency of agricultural plant protection and irrigation, and reduces manual labor intensity. Ordinary vehicle-mounted plant protection spraying components are simple to install but cannot be adjusted in height as needed. In actual use, the required spraying height varies depending on the environment. Therefore, we provide a rear-end adjustment mechanism for the unmanned agricultural vehicle. Utility Model Content

[0005] Preferably, both the upper and lower hinge frames are I-beam frames, and each frame consists of two sets of parallel hinge rods and a crossbar connecting the two sets of hinge rods.

[0006] Preferably, the drive cylinder is hinged to a hinge seat located at the middle of the crossbar of the lower hinge frame.

[0007] Preferably, the tailstock is arranged horizontally.

[0008] Preferably, spraying components for the sides of the vehicle are installed at both ends of the tail rack, and spraying components for the rear of the vehicle are installed on the side of the tail rack away from the rear of the vehicle.

[0009] This utility model has the following beneficial effects:

[0010] This utility model consists of a fixed frame, an upper hinge frame, a lower hinge frame, a movable frame, a tail frame, a reinforcing beam frame, and a drive cylinder. The tail frame is raised and lowered by extending and retracting the drive cylinder, thereby raising and lowering the entire spraying assembly to achieve the purpose of height adjustment.
