Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a telescopic lifting mechanism for a garbage truck, including a recycling door 2. The left end of the recycling door 2 is hinged and installed at the feeding port of the carriage 1 through a hinge shaft. Symmetrically fixed on the top of the recycling door 2 are rocker arms 8. The right end of the rocker arm 8 is hinged and installed with a first connecting rod 10. The other end of the first connecting rod 10 is rotatably installed with a clamping assembly 13 for fixing the garbage bin 14.

[0022] Symmetrically and vertically fixed at the tail of the carriage 1 are guide rails 7. The top of the guide rails 7 is arc-shaped, and a slideway 9 is provided in the guide rails 7. Respectively rotatably installed on both sides of the clamping assembly 13 are first sliders 12, and the first sliders 12 are slidably installed in the corresponding slideways 9 in a matching manner.

[0023] The clamping assembly 13 includes a moving plate. Both sides of the moving plate are rotatably installed with the corresponding first sliders 12 in a matching manner. Fixedly installed at the bottom of the moving plate is a fixing plate. Both sides of the fixing plate are rotatably installed with the corresponding first connecting rods 10 in a matching manner. Fixedly installed on one side of the moving plate is a limiting block 1301, and the limiting block 1301 limits the garbage bin 14. A guiding groove 1304 is provided in the fixing plate, and symmetrically arranged two clamping claws 1302 are slidably installed in the guiding groove 1304.

[0024] Installed on the fixing plate is a power assembly for driving the two clamping claws 1302 to move horizontally. The power assembly includes two air cylinders 1303. The two air cylinders 1303 are symmetrically and fixedly installed in the middle of the fixing plate, and the output end directions of the two air cylinders 1303 are opposite. The output ends of the two air cylinders 1303 are respectively fixedly installed with the corresponding clamping claws 1302 in a matching manner.

[0025] Fixedly installed on the side of the first slider 12 away from the clamping assembly 13 is a second wedge-shaped block 15. Both sides of the second wedge-shaped block 15 have inclined surfaces. Symmetrically arranged a first chute 19 and a second chute 11 are provided in the top of the guide rail 7. A through hole is provided in the guide rail 7 to communicate the first chute 19 and the second chute 11. Slidably installed in the first chute 19 is a second connecting rod 16. The second connecting rod 16 passes through the through hole and is slidably installed with the through hole. One end of the second connecting rod 16 extends into the second chute 11 and is fixedly installed with a second slider 17. The second slider 17 is slidably installed in the second chute 11. A spring 18 is fixedly installed between the second slider 17 and the second chute 11. The spring 18 is sleeved on the second connecting rod 16. Fixedly installed at the other end of the second slider 17 is a knocking assembly 5. The knocking assembly 5 includes a vertical rod. One end of the vertical rod is fixedly connected with the second slider 17, and the other end of the vertical rod is fixedly installed with a knocking rod, and the knocking rod is perpendicular to the vertical rod.

[0026] One end of the second connecting rod 16 away from the second slider 17 is fixedly installed with a first wedge block 6, and the first wedge block 6 is slidably installed in the first chute 19. Both sides of the first wedge block 6 have inclined surfaces, and the inclined surfaces of the first wedge block 6 are slidably engaged with the inclined surfaces of the second wedge block 15 to push the second connecting rod 16 to move in the direction of the second slider 17.

[0027] A driving assembly for driving the recycling door 2 to rotate around its hinge shaft is fixedly installed on the carriage 1. The driving assembly includes two electric push rods 4, the two electric push rods 4 are symmetrically and fixedly installed on the top of the carriage 1, and mounting blocks 3 are symmetrically and fixedly installed on the top of the recycling door 2. The mounting blocks 3 are located on the left side of the recycling door 2, and the mounting blocks 3 are hingedly engaged with the output ends of the corresponding electric push rods 4.

[0028] The working principle of the telescopic lifting mechanism of the garbage truck provided by the present utility model is as follows:

[0029] Place the garbage bin 14 between the two jaws 1302, and start the two cylinders 1303. The output ends of the two cylinders 1303 contract to drive the two jaws 1302 to clamp the garbage bin 14.

[0030] Start the electric push rod 4. The output end of the electric push rod 4 extends to drive the recycling door 2 to flip upwards, thereby opening the recycling door 2. While the recycling door 2 flips upwards, it drives the rocker 8 and the first connecting rod 10 to move upwards. The first connecting rod 10 first drives the clamping assembly 13 to move upwards. At the same time, the upward movement of the clamping assembly 13 drives the first slider 12 to move upwards along the slideway 9, and the clamping assembly 13 drives the garbage bin 14 to move upwards.

[0031] When the first slider 12 enters the arc part of the slideway 9 along the slideway 9, the first slider 12 decelerates due to the friction with the inner wall of the turning part of the guide rail 7. At this time, the speed of the first connecting rod 10 and the clamping assembly 13 remains unchanged. Therefore, the clamping assembly 13 starts to flip around the rotating shaft of the first slider 12 at this moment. During the movement of the first slider 12 along the slideway 9, the second wedge block 15 is slidably engaged with the first wedge block 6, and the second wedge block 15 pushes the first wedge block 6 to slide into the first chute 19. The first wedge block 6 drives the second slider 17 to slide out of the second chute 11 through the second connecting rod 16 and stretches the spring 18. The movement of the second slider 17 drives the knocking assembly 5 away from the guide rail 7. When the first slider 12 slides to the arc end of the guide rail 7, the first slider 12 is restricted by the end of the guide rail 7 and stops sliding. The first connecting rod 10 drives the clamping assembly 13 to flip, so that the garbage bin 14 reaches the maximum tilt angle, so that the opening of the garbage bin 14 reaches the dumping position at the garbage recycling port on the carriage 1, and the garbage in the garbage bin 14 is dumped into the carriage 1. The limit block 1301 on the clamping assembly 13 plays a limiting role on the garbage bin 14 to prevent the garbage bin 14 from sliding into the carriage 1 when it flips.

[0032] Meanwhile, the second wedge block 15 just disengages from the first wedge block 6, and the second slider 17 slides into the second chute 11 under the action of the spring 18, thereby driving the knocking assembly 5 to move towards the guide rail 7, so that the knocking assembly 5 knocks the first connecting rod 10 to generate vibration. The first connecting rod 10 generates a vibration effect on the garbage bin 14 through the clamping assembly 13, so that the garbage adhered to the wall of the garbage bin 14 is more likely to fall off, improving the garbage collection effect.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
