[0025] See also Figure 2 and Figure 3 In order to quickly open and close the tail plate 711, the inner cavity of the lifting cylinder 71 is movably connected to the outer wall of the resistance liquid 72, the inner wall of the lifting cylinder 71 is slidably connected to the outer wall of the piston head 73, and the outer diameter of the piston head 73 is the same as the inner diameter of the lifting cylinder 71. The piston head 73, the piston rod 74 and the rotating ring 76 are all integrated structures, which is convenient for driving the entire device to extend and retract.

[0026] See also Figure 4In order to quickly dump and discharge the garbage in the garbage collection bin 5, the dumping mechanism 8 includes a discharge bearing 81, the outer wall of the discharge bearing 81 is embedded and connected with both sides of the inner wall of the garbage collection bin 5, the middle part of the discharge bearing 81 is provided with a discharge shaft rod 82, and the outer wall of the discharge shaft rod 82 is provided with a discharge plate 83, and the discharge plate 83 is bolted with a load-bearing sensor 84. A certain value is set by the load-bearing sensor 84, and the garbage in the garbage collection bin 5 can be weighed through the action of the load-bearing sensor 84, so that the amount of garbage can be accurately controlled. The lower end of the discharge plate 83 is fixedly connected with a mounting frame 8 5. A telescopic rod 86 is hinged on the inner side of the mounting frame 1 85, and a mounting frame 2 87 is hinged on one end of the telescopic rod 86. A fixed bearing 88 is overlapped on the inner wall of the mounting frame 2 87, and a fixed end shaft 89 is inserted into the inner wall of the fixed bearing 88. The inner wall of the unloading bearing 81 is inserted into the outer wall of the unloading shaft rod 82, and the outer wall of the unloading shaft rod 82 is fixedly connected to one side of the unloading plate 83. The outer dimensions of the unloading plate 83 are the same as and consistent with the inner dimensions of the garbage collecting bin 5. When the unloading plate 83 is in a horizontal state, it fits with the inner wall of the garbage collecting bin 5, thereby preventing garbage from falling into the bottom wall of the garbage collecting bin 5.

[0027] Working principle: First, the tail plate 711 can rotate around the rotating shaft 710 under the action of the fixed block 79. When unloading is not needed, the tail plate 711 is rotated to a vertical state, so that the tail plate 711 is in contact with the discharge port 6 on one side of the garbage collection bin 5, and can be used directly as the garbage collection bin 5. However, when it is necessary to unload the garbage, the tail plate 711 is rotated to a horizontal state. At this time, the gravity of the piston rod 74 and the tail plate 711 is exactly equal to the elastic force of the spring 75. The tail plate 711 and the bottom surface of the garbage collection bin 5 are inclined to form an outlet for garbage discharge. The tail plate 711 drives the rotating rod 77 and the rotating ring 76 to move downward through the cooperation of the fixed block 79 and the stopper 78. At this time, the piston head 73 moves downward through the piston rod 74 to squeeze the spring 75 and the resistance liquid 72 below. The resistance liquid 72 The locking cam 75 is pressed against the locking cam 76 to release the locking cam 76, and the locking cam 76 is pressed against the support cam 74 to release the locking cam 76. The locking cam 76 is pressed against the support cam 74 to release the locking cam 76.

[0028] Then, when the weight of the garbage reaches the set value, the telescopic rod 86 is electrically connected to the power output end and the signal output end of the controller, and the pressure sensor is electrically connected to the power output end and the signal input end of the controller, so as to control the telescopic rod 86 to be extended and retracted. The telescopic end of the telescopic rod 86 can be rotated on the inner side of the mounting seat through the fixed end shaft 89 and the fixed bearing 88 sleeved on the fixed end shaft 89, so as to complete the change of the inclination angle of the unloading plate 83. At this time, the unloading plate 83 is rotated in the two unloading bearings 81 under the action of the unloading shaft rod 82, and finally the dumping operation of the garbage is realized without manual unloading. The above is the working process of the whole device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
