[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1 to 4According to an embodiment of this utility model, a garbage tipping and dumping device for a pure electric sanitation vehicle is provided. Of course, this garbage tipping and dumping device can also be used on a sanitation vehicle 10 driven by gasoline or hybrid power. Specifically, it can be installed on a sanitation vehicle 10 with a garbage discharge outlet 110 at the rear of the vehicle body 11. A tailgate 14 that can be tipped open is installed at the garbage discharge outlet 110. The rear of the vehicle body 11 of the pure electric sanitation vehicle 10 is rotatably connected to the chassis 13. The garbage tipping and dumping device includes a first motor 20, a pull rope 30, and a belt conveyor 40. The first motor 20 is fixedly installed on the front 12 of the pure electric sanitation vehicle 10. The first end of the pull rope 30 is fixedly connected to the front of the vehicle body 11, and the second end of the pull rope 30 is fixed to the output shaft of the first motor 20. The belt conveyor 40 is located at the bottom of the vehicle body 11 and extends from the front of the vehicle body 11 to the rear of the vehicle body 11.

[0027] The garbage tipping and dumping device for pure electric sanitation vehicles with the above-described structure requires the rear of the vehicle compartment 11 to be aligned with the garbage receiving device (e.g., garbage pit) when it is necessary to empty the garbage inside the compartment 11. Then, the first motor 20 is started, which lifts the front of the compartment 11 via the pull rope 30, creating a certain angle. Next, the belt conveyor 40 is activated to push the garbage inside the compartment 11 out through the garbage discharge outlet 110. This method allows for rapid emptying of the garbage inside the compartment 11. Furthermore, during garbage discharge, the angle of the compartment 11 remains within a small range, ensuring that the center of gravity of the compartment 11 is kept low, thereby improving the stability of the sanitation vehicle 10 and enhancing the safety of sanitation operations.

[0028] In this exemplary embodiment, the belt conveyor 40 includes two drive shafts 41, a belt 46 sleeved between the two drive shafts 41, and a second motor 43 that drives at least one drive shaft 41 to rotate. The drive shafts 41 are rotatably connected to the carriage 11. Furthermore, the belt conveyor 40 also includes multiple support shafts 42 located inside the belt 46 and disposed between the two drive shafts 41. The support shafts 42 are rotatably connected to the carriage 11. By employing multiple support shafts 42, the belt conveyor 40 can be effectively supported, dispersing the pressure exerted on the belt conveyor 40 by waste, thereby preventing the belt conveyor 40 from shortening its service life due to excessive deformation.

[0029] In this exemplary embodiment, at least a portion of the support shaft 42 is provided with a cam 44, which is rotatably connected to the support shaft 42 and protrudes from the outer wall of the support shaft 42. A third motor 45, which drives at least a portion of the support shaft 42 to rotate, is fixedly mounted on the carriage 11. With this configuration, during the waste transport process of the belt conveyor 40, the third motor 45 is activated. The third motor 45 drives the support shaft 42 to rotate, and the cam 44 on the support shaft 42 periodically contacts the belt 46 of the belt conveyor 40, thereby causing the belt 46 to vibrate. This vibration helps to shake off the waste attached to the surface of the belt 46.

[0030] In this exemplary embodiment, a mounting portion 112 protrudes from the front of the carriage 11 towards the front end 12. One end of the belt conveyor 40 extends into the mounting portion 112, and the first end of the pull rope 30 is fixedly connected to the top of the mounting portion 112. By configuring the mounting portion 112, the end of the belt conveyor 40 is concealed, preventing waste from seeping into the lower part of the carriage 11 through the gap between the front end of the belt conveyor 40 and the carriage 11. At the same time, the mounting portion 112 can also serve as a base for connecting the pull rope 30 to the carriage 11.

[0031] In this exemplary embodiment, a buffer device 50 is provided between the mounting part 112 and the chassis 13. Specifically, the buffer device 50 may be a rubber pad. During the process of moving under the carriage 11, the buffer device 50 can play a buffering role to prevent a violent collision between the carriage 11 and the chassis 13.

[0032] To further prevent debris from entering the bottom of the belt 46, in this exemplary embodiment, a baffle 113 is fixedly provided on the upper part of the mounting portion 112, and the free end of the baffle 113 abuts against the outer surface of the belt 46. The baffle 113 serves to restrict debris from entering the mounting portion 112 through the gap between the belt 46 and the carriage 11.

[0033] In this exemplary embodiment, a scraper 114 is fixedly installed at the rear of the carriage 11, with the free end of the scraper 114 abutting against the outer surface of the belt 46. With this configuration, when the belt conveyor 40 transports waste, the scraper 114 will effectively remove the waste from the surface of the belt conveyor 40 to keep its surface clean and tidy.

[0034] In this exemplary embodiment, a garbage inlet 111 is provided on the top of the carriage 11. A door 15 is installed at the garbage inlet 111 via a first hinge 17, and a handle 16 is installed on the door 15. When it is necessary to put garbage into the carriage 11, the door 15 can be opened first, and then the garbage can be poured into the carriage 11 through the garbage inlet 111. After the garbage is poured out, the door 15 can be closed to prevent odors from overflowing from the carriage 11.

[0035] In this exemplary embodiment, the tailgate 14 is rotatably connected to the garbage outlet 110 via a second hinge 18, and a hydraulic rod 19 is installed between the tailgate 14 and the truck body 11 to drive the tailgate 14 to flip open. With this configuration, when dumping garbage, the hydraulic rod 19 drives the tailgate 14 to flip open upwards, and the garbage can be discharged from the truck body 11 through the garbage outlet 110.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
