Folding and unfolding of the conveyor 4: By retracting the conveying folding cylinder 43, the discharge end 42 of the conveyor 4 is folded onto the conveying end 41, facilitating the movement, relocation, or storage of the unloading conveyor; by extending the conveying folding cylinder 43, the discharge end 42 of the conveyor 4 is unfolded, facilitating the operation of the unloading conveyor.

[0038] Working principle

[0039] The dump truck pours materials into the feed hopper 2 through the dump truck crawling platform 3. The materials fall from the discharge port of the feed hopper 2 onto the conveyor 4 and are then conveyed out by the conveyor 4.

[0040] During relocation, the worm gear 11 can be driven to rotate by the rotary hydraulic motor 12. The worm gear 11 drives the outer ring of the slewing bearing 10 to rotate, causing the drive wheel 7 to rotate accordingly. Then, the walking hydraulic motor 20 directly drives the wheel axle 15 to rotate, and the two wheels 14 follow the wheel axle 15 to rotate, thereby realizing the straight or lateral movement of the batching conveyor.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
