The bottom of the shaft seat is fixedly connected to the top of the carriage. The front end of the pull rod is hinged to a docking arm. One end of the docking arm away from the rotating shaft is hinged to a tipping device. The lower part of the inner wall of the tipping device is hinged to a hinged arm, and the hinged arm is hinged and assembled with the upper part of the outer wall of the carriage. A rear plate is installed on the back of the carriage. A cross beam is welded at the center of the rear plate. Two hinge pieces one are installed on the lower surface of the cross beam on the left and right sides. A hinged tailgate is installed at the bottom of the two hinge pieces one. An unloading chute opening is installed at the lower part of the back of the carriage. A hydraulic cylinder one is hinged to the back of the cross beam. A connecting arm is installed at the telescopic end of the hydraulic cylinder one. The connecting arm is hinged and installed with the back of the hinged tailgate. A conveyor belt assembly is arranged in the inner cavity of the carriage. A side turning plate is opened and closed on the outer wall of the carriage. A lower beam support is arranged at the bottom of the side turning plate. A hinge piece two is hinged between the side turning plate and the lower beam support. A hydraulic cylinder two is arranged between the outer wall of the lower beam support and the outer wall of the side turning plate.

[0005] As a further solution of the present invention: A welding block is fixedly connected to the upper part of the outer wall of the lower beam support. The welding block is hinged to a hydraulic cylinder two. A shaft rod is installed at the telescopic end of the hydraulic cylinder two. Both ends of the shaft rod are rotatably connected to an assembly block, and the assembly block is fixedly connected to the outer wall of the side turning plate.

[0006] As a further solution of the present invention: a side panel is fixedly connected to the lower part of the outer wall of the side flap plate, an axle seat is arranged on the inner side of the side panel, the axle seat is fixedly connected to the outer wall of the side flap plate, a connecting shaft is installed at the axial center part of the axle seat, and both ends of the connecting shaft are installed on the inner sides of the two groups of side panels.

[0007] As a further solution of the present invention: the conveyor belt assembly includes an assembly frame for assembly in the box inner frame, and a driving motor is installed at the active end of the assembly frame, the driving end of the driving motor is fixedly connected to a driving shaft, and the outer wall of the driving shaft is transmission-connected to a belt.

[0008] As a further solution of the present invention: a driven shaft is installed at the driven end of the assembly frame, and the outer wall of the driven shaft is connected to the belt transmission.

[0009] As a further solution of the present invention: the front and rear ends of the assembly frame are both equipped with bearing seat bodies, and two groups of the bearing seat bodies are respectively assembled with the ends of the driving shaft and the driven shaft.

[0010] As a further solution of the present invention: sprocket wheels are installed on the outer walls of the driven shaft and the driving shaft, and the outer walls of the sprocket wheels are transmission-connected with chains, a scraper is fixedly connected to the inner side of the outer wall of the chain, a belt is arranged at the lower part of the scraper, and the belt is arranged in contact with the scraper.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention controls the operation of the hydraulic cylinder to drive the pull rod to extend and retract, and the docking arm connected to one end of the pull rod is hinged to the top flip. Therefore, after the rotating shaft is extended and retracted, the docking arm flips and drives the top flip and side flip. At the same time, the hinged arm hinged at the lower part of the top flip and the outer wall of the box are hinged, so as to achieve stability during the top flip and side flip, and at the same time, the top of the box is closed.

[0012] The present invention controls the operation of the second hydraulic cylinder installed on the lower beam support and hinged with the welding block to push the shaft rod to extend and shorten. During the extension process, the shaft rod will push the side flap connected to the assembly block forward, but the side flap plate and the lower beam support are hinged by the second hinge. Therefore, the side flap plate can only be flipped sideways and perpendicular to the conveyor belt assembly under the push of the second hydraulic cylinder.

[0013] The present invention starts the driving motor to operate, and drives the driving motor and the sprocket wheel installed on the outer wall of the chain to rotate. The sprocket wheel meshes with the chain and drives the chain to transmit. The scraper installed on the inner side of the chain is on the belt. At the same time, the driving shaft connected to the driving end of the driving motor transmits the belt, that is, the scraper scrapes the material on the belt. The belt and the scraper move synchronously, and the material between the two groups of scrapers will be pushed out by the scraper after reaching the discharge slot.
