[0022] It should be noted that the lifting mechanism 2 includes a hydraulic cylinder 21, a chain 24, a lifting frame 25 and a bucket rack 26. The cylinder body of the hydraulic cylinder 21 is vertically arranged on the frame 1 and the upper end of its piston rod is provided with a fixed shaft 22. The two sides of the fixed shaft 22 are rotatably connected with sprockets 23, and each sprocket 23 is connected with a chain 24. One end of the chain 24 is connected to the frame 1, and the other end of the chain 24 is connected to the lifting frame 25. The bucket rack 26 is arranged above the lifting frame 25 and is evenly distributed with a number of hooks 262 inserted into the edge of the trash can. The trash can full of trash is hung on the hooks 262 for lifting. The two sides of the lifting frame 25 are respectively provided with connecting shafts 251 inserted into the slots 261 on the bucket rack 26, and the two sides of the bucket rack 26 are respectively provided with rollers 27 that are rollingly connected to the guide rails 252 on both sides of the frame 1.

[0023] In addition, the knocking mechanism 3 includes a fixed frame 31, a driving shaft 32, a chain 2 34, a counterweight 36 and a striking rod 37. The fixed frame 31 is arranged on the side of the frame 1 and is rotatably connected to the driving shaft 32. The driving shaft 32 is inserted into the sleeve 311 on the fixed frame 31 to enhance the stability of the driving shaft 32 during rotation. A sprocket 2 33 is installed at one end of the driving shaft 32. The sprocket 2 33 is connected to a chain 2 34. One end of the chain 2 34 is connected to the lifting frame 25, and the other end of the chain 2 34 is connected to the counterweight 36 that is slidably connected to the side slide rail 35 of the frame 1.

[0024] Specific implementation and principle:

[0025] When in use, the device of the present application is installed on a garbage transport truck. When it is necessary to dump a garbage can full of garbage into the garbage transport truck:

[0026] S1, hang the edge of the garbage can filled with garbage on the hook 262 on the hanging rack 26;

[0027] S2, the piston rod of the control hydraulic cylinder 21 is extended, and the sprocket 23 on the connecting shaft 251 drives the lifting frame 25 to move upward through the chain 24, so that the roller 27 of the barrel hanging frame 26 moves upward along the guide rail 252 on the frame 1;

[0028] S3, when moving to the bending part of the rack 1, the trash can is dumped;

[0029] S4. At the same time, when the lifting frame 25 moves upward, the counterweight block 36 on the second chain 34 moves downward along the slide rail 35, and the drive shaft 32 is rotated through the second sprocket 33. The driving plate 38 on the drive shaft 32 drives the slider 39 to move in the slide groove 371 on the striking rod 37, so that the striking rod 37 swings back and forth, thereby knocking the outer wall of the trash can, so that the garbage attached to the trash can is shaken off.

[0030] In summary, the present application uses the hydraulic cylinder 21 to drive the garbage can filled with garbage on the hanging bucket rack 26 to move up along the guide rail 252 of the frame 1 and dump it into the garbage transport truck. During the upward movement of the hanging bucket rack 26, the striking rod 37 is swung back and forth, thereby knocking on the outer wall of the garbage can, so that the garbage attached to the garbage can is shaken off.

[0031] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
