[0001] The utility model relates to a tipping device for a garbage truck compartment, belonging to the technical field of garbage truck compartment tipping. Background Art

[0002] With the development of cities in China, citizens have higher and higher requirements for the living environment, which urges the sanitation department to have higher sanitation standards in the process of garbage collection, transportation and treatment. At present, most cities still use traditional garbage trucks that require manual unloading of garbage. This garbage transfer method requires special personnel to unload the garbage from the garbage truck, increasing the labor intensity of workers, prolonging the sanitation working hours, consuming a large amount of energy, and having a high operating cost.

[0003] There are also self-tipping garbage trucks in the prior art. A lifting oil cylinder is provided at the front end of the garbage truck compartment. When the front end of the compartment rises, the compartment tilts, and the garbage in the garbage truck compartment slides downward by its own gravity to leave the compartment, realizing self-unloading of garbage. However, in order to increase the transportation volume, the garbage in the existing garbage truck compartments is generally compressed, and the garbage contains some moisture. After compression, the garbage is very tightly compressed into a ball and tightly stuffed in the compartment, making it very difficult to discharge the garbage from the compartment.

[0004] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

[0005] Aiming at the deficiencies in the background art, the utility model provides a tipping device for a garbage truck compartment, which can use the material pushing claws of the material system to push the compressed garbage upward and outward from the bottom, so that the garbage in the compartment is unloaded from the bottom to the garbage pit.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

The rotating shafts of the driving roller and the driven roller are parallel to the side baffle of the compartment. A conveyor belt is wound around the driving roller and the driven roller. Preferably, the conveyor belt is composed of a plurality of narrow-width plates hinged to each other. A plurality of material pushing claws are arranged at equal intervals on the outer side of the conveyor belt.

[0009] Furthermore, the driving roller and the driven roller are respectively arranged on both sides of the bottom inside the compartment, the conveyor belt drives in the direction of the discharging side of the compartment, the side baffle on the discharging side of the compartment includes an upper baffle and a lower baffle, and the side baffle on the opposite side of the discharging side of the compartment is closed.

[0010] Further, there are two sets of material pushing systems, which are symmetrically arranged with respect to the central symmetry plane of the carriage, and the material pushing claws of the two material pushing systems push the garbage towards both sides of the carriage respectively.

[0011] Further, the side baffles on both sides of the carriage each include an upper baffle and a lower baffle.

[0012] Further, the upper end of the upper baffle is rotatably installed at the top of the carriage, and the lower end of the lower baffle is rotatably installed at the bottom of the carriage.

[0013] Further, a push-pull curved arm is provided on the outer side of the lower baffle. The push-pull curved arm is arc-shaped. One end of the push-pull curved arm is hinged to the outer side of the lower baffle, and the other end is hinged to the slider.

[0014] Further, the slider is slidably installed on the slide rail. The slider is driven by a first oil cylinder. The rear end of the first oil cylinder is fixed to the bottom of the carriage, and the telescopic end of the first oil cylinder is connected to the slider.

[0015] Further, each upper baffle is configured with a second oil cylinder. The rear end of the second oil cylinder is rotatably installed at the top of the carriage, and the telescopic rod of the second oil cylinder is hinged to the upper baffle.

[0016] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0017] 1. The material pushing claws of the material pushing system pull the compressed garbage on it while pushing it outwards, so that the compressed garbage in the carriage is unloaded outwards from bottom to top; it can be unloaded to one side of the carriage or to both sides of the carriage.

[0018] 2. The lower baffle on the garbage unloading side is opened to form a slope, so that the garbage slides down along the lower baffle, preventing the unloaded garbage from clinging to the carriage, which is not convenient for the garbage to flow to outside the garbage pit and is also convenient for moving the garbage truck after the garbage is unloaded.

[0026] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation manner of the present utility model will now be described with reference to the accompanying drawings.

[0027] As Figures 1-3 shown, the present utility model provides a tipping device for a garbage truck compartment, including a compartment. The side baffles of the compartment both include an upper baffle 1 and a lower baffle 2. When tipping garbage, one or both side baffles are opened.

[0028] A material pushing system is provided at the bottom inside the compartment. The material pushing system includes a driving roller 3 and a driven roller 4. The driving roller 3 is driven by a driving device (not shown in the figure). The axes of the driving roller 3 and the driven roller 4 are parallel to the side baffles of the compartment. A conveyor belt 5 is wound around the driving roller 3 and the driven roller 4. Preferably, the conveyor belt 5 is composed of a plurality of narrow-width plates hinged to each other. A plurality of material pushing claws 6 are arranged at equal intervals on the outer side of the conveyor belt 5.

[0029] As Figure 2 shown, in one embodiment, there is one set of the material pushing system. The driving roller 3 and the driven roller 4 are respectively arranged on both sides of the bottom inside the compartment. The conveyor belt 5 is driven in the direction of the discharge side of the compartment. In this embodiment, the side baffle on the discharge side of the compartment includes an upper baffle 1 and a lower baffle 2. The side baffle on the opposite side of the discharge side of the compartment is closed. The upper end of the upper baffle 1 is rotatably installed on the top of the compartment, and the lower end of the lower baffle 2 is rotatably installed on the bottom of the compartment.

[0030] As Figure 3 shown, in another embodiment, there are two sets of the material pushing system. The two sets of the material pushing system are symmetrically arranged with respect to the central symmetry plane of the compartment. The material pushing claws 6 of the two material pushing systems respectively push the garbage to both sides of the compartment. In this embodiment, the side baffles on both sides of the compartment both include an upper baffle 1 and a lower baffle 2. The upper end of the upper baffle 1 is rotatably installed on the top of the compartment, and the lower end of the lower baffle 2 is rotatably installed on the bottom of the compartment.

[0031] Further, a plurality of pressure-bearing idle rollers 7 are arranged between the driving roller 3 and the driven roller 4 along the movement direction of the conveyor belt 5 to support the conveyor belt 5.

[0032] On the outer side of the lower baffle 2, there is a push-pull curved arm 8. The push-pull curved arm 8 is arc-shaped. One end of the push-pull curved arm 8 is hinged to the outer side of the lower baffle 2, and the other end is hinged to the slider 10.

[0033] The slider 10 is slidably mounted on the slide rail 9. The slider 10 is driven by a first oil cylinder 11. The rear end of the first oil cylinder 11 is fixed to the bottom of the carriage. The telescopic end of the first oil cylinder 11 is connected to the slider 10. When the telescopic rod of the first oil cylinder 11 extends, the lower baffle 2 can be pushed to rotate upward to be perpendicular to the bottom plane of the carriage through the push-pull curved arm 8. At this time, the garbage in the carriage is blocked. When the telescopic rod of the first oil cylinder 11 contracts, the lower baffle 2 rotates to the side, so that the garbage slides down along the lower baffle 2 from the carriage.

[0034] As Figure 4 , each upper baffle 1 is provided with a second oil cylinder 12. The rear end of the second oil cylinder 12 is rotatably mounted on the top of the carriage. The telescopic rod of the second oil cylinder 12 is hinged to the upper baffle 1. When dumping garbage, the second oil cylinder 12 pushes the upper baffle 1 to open, which is convenient for dumping garbage.

[0035] The specific working principle of the present utility model:

[0036] At the bottom inside the carriage, there is a material-pushing system. The material-pushing system includes a driving roller 3 and a driven roller 4. A conveyor belt 5 is wound around the driving roller 3 and the driven roller 4. A plurality of material-pushing claws 6 are arranged at equal intervals on the outer side of the conveyor belt 5. When dumping garbage, the conveyor belt 5 rotates to pull the compressed garbage on it outward while pushing, so that the compressed garbage in the carriage is unloaded from the bottom to the outside upward; it can be unloaded to one side of the carriage or to both sides of the carriage.

[0037] On the outer side of the lower baffle 2, there is a push-pull curved arm 8. The push-pull curved arm 8 is arc-shaped. When the telescopic rod of the first oil cylinder 11 extends, the lower baffle 2 can be pushed to rotate upward to be perpendicular to the bottom plane of the carriage through the push-pull curved arm 8. At this time, the garbage in the carriage is blocked. When the telescopic rod of the first oil cylinder 11 contracts, the lower baffle 2 rotates to the side, so that the garbage slides down along the lower baffle 2 from the carriage. The lower baffle 2 on the garbage-unloading side is opened to form a slope, so that the garbage slides down along the lower baffle 2, preventing the unloaded garbage from clinging to the carriage, which is not convenient for the garbage to flow to outside the garbage pit and is also convenient for moving the garbage truck after the garbage is unloaded.
