DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Reference Figure 1 The utility model provides a garbage truck bucket shaking device, including a shell 1. When in use, the shell 1 is fixedly installed on the garbage truck. A guide hopper 2 and a bucket cylinder 4 are installed inside the shell 1. The upper part of the guide hopper 2 is hinged to the top of the shell 1. A limit strip 201 is installed on the inner wall of the guide hopper 2. When the garbage bin 3 is pushed into the guide hopper 2, it is at the lowering of the limit strip 201. A position sensor 101 is installed on the shell 1. A baffle 202 matching the position sensor 101 is installed on the guide hopper 2. In actual application, the position sensor 101 can adopt an infrared beam or a Hall sensor. The cylinder body of the bucket cylinder 4 is hinged to the shell 1. A buffer mechanism is installed on the outer wall of the guide hopper 2. The piston rod of the bucket cylinder 4 is connected with the buffer mechanism, thereby pushing the guide hopper 2 to flip on the shell 1. When the guide hopper 2 flips, the garbage bin 3 remains stable inside it under the action of the limit strip 201.

[0018] Reference Figure 2 A motor 5, a driving disc 6 and a reciprocating mechanism 7 are installed on the back of the housing 1. The motor 5 is connected to the driving disc 6 by a belt. A connecting rod 8 is provided between the driving disc 6 and the reciprocating mechanism 7. One end of the connecting rod 8 is rotatably connected to the disc surface of the driving disc 6, and the other end is hinged to the reciprocating mechanism 7. A connecting ring 203 is installed on the upper end of the guide hopper 2;

[0019] During operation, when the bucket cylinder 4 pushes the guide hopper 2 to flip to a horizontal state, the reciprocating mechanism 7 engages with the connecting ring 203, and then the upper end of the guide hopper 2 is tilted downward under the drive of the motor 5. The reciprocating mechanism 7 moves downward to a set point and then disengages from the connecting ring 203, and the guide hopper 2 is reset to a horizontal state under the drive of the buffer mechanism; the reciprocating mechanism 7 repeatedly engages and disengages with the connecting ring 203 under the drive of the motor 5, thereby realizing repeated shaking of the guide hopper 2.

[0020] Reference Figure 3The buffer mechanism includes a buffer seat 204, which is rotatably connected to the outer wall of the guide hopper 2. The buffer seat 204 is provided with a buffer groove 205, in which a connecting column 207, a top block 206 and a buffer spring 208 are installed. The connecting column 207 is rotatably connected to the piston rod of the bucket cylinder 4, and the top block 206 is kept free to slide in the buffer groove 205. The top block 206 is installed between the connecting column 207 and the buffer spring 208; when the reciprocating mechanism 7 drives the upper end of the guide hopper 2 to tilt downward through the connecting ring 203, since the piston rod of the bucket cylinder 4 is no longer extended, the connecting column 207 drives the top block 206 to compress the buffer spring 208; when the reciprocating mechanism 7 is separated from the connecting ring 203, the guide hopper 2 returns to a horizontal position under the action of the buffer spring 208.

[0021] Reference Figure 4 The reciprocating mechanism 7 includes a slide rail 701, a trapezoidal stopper 702 is installed on the housing 1 on both sides of the slide rail 701, a stabilizing frame 703 is provided between the slide rail 701 and the connecting rod 8, a telescopic rod 704 is slidably installed on the stabilizing frame 703, one end of the telescopic rod 704 is hinged to the connecting rod 8, and the other end is connected to the slider of the slide rail 701;

[0022] Two hooks 705 are installed in a mirror-like manner on the slider of the slide rail 701. The middle part of the hook 705 is rotatably connected to the slider of the slide rail 701, and the tail part of the hook 705 extends to the outside of the slide rail 701. A reset groove 706 is installed on the slider between the two hooks 705. A reset spring 707 is installed in the reset groove 706. Telescopic columns 708 are installed at both ends of the reset spring 707. One end of the telescopic column 708 is connected to the reset spring 707, and the other end is tightly pressed against the hook 705. The position where the telescopic column 708 contacts the hook 705 is between the tail end of the hook 705 and the connection between it and the slide rail 701. The outer side of the head end of the hook 705 is an inclined surface inclined toward the other hook.

[0023] The reset spring 707 is always in a compressed state. Under its action, the head ends of the two hooks 705 are pressed against each other. When the head end of the hook 705 contacts the connecting ring 203, the connecting ring 203 slides along the outer inclined surface of the head end of the hook 705 to separate the two hooks 705. The connecting ring 203 enters between the two and then closes again to achieve the engagement between the reciprocating mechanism 7 and the connecting ring 203. During the downward movement of the slider of the slide rail 701 driven by the motor 5, the tail end of the hook 705 contacts and slides with the inclined surface of the trapezoidal stopper 702, so that the tail ends of the two hooks 705 are close to each other and the head ends are separated to achieve the separation of the reciprocating mechanism 7 and the connecting ring 203.

[0024] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
