[0002] A belt conveyor is a continuous conveying device used to transport materials. It consists of one or more belts that wrap around two or more rollers, one of which drives the belt's movement. Belt conveyors are widely used in mines, ports, factories, warehouses, and other places for handling coal, ore, grain, packaged goods, etc.

[0003] Currently available belt conveyor cleaning integrated boxes (hereinafter referred to as "cleaning boxes") typically have a collection hopper under the conveyor belt to collect cleaning materials, and nozzles are installed to periodically rinse the inner wall of the collection hopper. However, this design has some problems: the nozzles have blind spots, the collection hopper is not thoroughly rinsed, sewage discharge is not smooth, and abnormal situations such as material accumulation may occur. In addition, the stable operation of the cleaning box is affected by factors such as unstable water sources, small water volume, and insufficient water pressure. To achieve the ideal rinsing effect, it is often necessary to consume a large amount of water resources or increase the investment in electrical equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a flushing device for the collection hopper of a cleaning box, which solves the problems existing in the prior art, solves the problem of flushing and sewage discharge of the collection hopper in a low-cost manner, and improves the operational stability of the cleaning box.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A flushing device for a cleaning box hopper includes a flushing mechanism and a water tank. The flushing mechanism is disposed inside the cleaning box hopper and includes a cover plate, a guide plate, and a water outlet control plate. The cover plate is fixed relative to the hopper. The lower surface of the guide plate is attached to the bottom wall of the hopper and forms a water passage cavity communicating with the water tank. The water passage cavity is arranged along the side wall of the hopper, and a water outlet facing the bottom of the hopper is provided on the bottom side of the water passage cavity. The water outlet control plate is height-adjustably fitted to the side of the water passage cavity to adjust the effective opening size of the water outlet.

[0007] The flushing mechanism forms a water passage cavity that is connected end to end along the side wall of the hopper, and the water passage cavity is connected to the water tank through at least one water pipe.

[0008] Preferably, the water tank is equipped with an electric valve at its outlet.

[0009] Preferably, a plurality of rectifier rings are provided inside the water passage cavity, the rectifier rings are fixed to the side wall of the water passage cavity and do not contact the bottom wall of the water passage cavity; a booster pump is provided between the water tank and the water passage cavity.

[0010] The cover plate is a U-shaped piece with the opening facing downwards and is installed on the side wall of the hopper; the outer side of the guide plate extends upwards to form a connecting plate that seals against the outer side of the cover plate; a plurality of screws are provided on the inner side of the cover plate, and the water outlet control plate is provided with waist holes sleeved on the screws, the length direction of the waist holes being arranged along the height direction.

[0011] Preferably, the deflector is made of rubber.

Detailed Implementation

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] refer to Figure 1-5 As shown, this utility model discloses a flushing device for a cleaning box hopper, including a flushing mechanism and a water tank 1;

[0027] The flushing mechanism is installed inside the collection hopper b of the cleaning box a, and includes a cover plate 2, a guide plate 3, and a water outlet control plate 4. The cover plate 2 is fixed relative to the collection hopper b. The lower surface of the guide plate 3 is attached to the bottom wall of the collection hopper b and forms a water passage cavity 20 communicating with the water tank 1 with the cover plate 2. The water passage cavity 20 is arranged along the side wall of the collection hopper b, and the bottom side of the water passage cavity 20 is provided with a water outlet 21 facing the bottom of the collection hopper b. The water outlet control plate 4 is height-adjustable and fitted to the side of the water passage cavity 20 to adjust the effective opening size of the water outlet 21.

[0028] Through the above-described scheme, this invention achieves water curtain flushing of the collection hopper b by setting a water passage chamber 20 on the side wall of the collection hopper b. The water passage chamber 20 has an outlet 21 whose size can be adjusted by the water outlet control plate 4. Compared with the nozzles in the prior art, this invention has a larger instantaneous water output and the water curtain output is adjustable, which can efficiently flush the accumulated material in the collection hopper b while ensuring economic benefits. The water curtain can also agitate the water in the collection hopper b, prevent material sedimentation, improve the sewage discharge effect, and almost eliminate the flushing blind spot. In addition, this invention can use the water tank 1 to store a certain amount of water and open the water passage between the water tank 1 and the water passage chamber 20 when the collection hopper b needs to be flushed. This provides higher redundancy for the on-site water supply pressure and effectively avoids the problem of the nozzle spray angle not meeting expectations due to insufficient on-site water pressure or water pressure fluctuations.

[0029] The following are specific embodiments of the present invention.

[0030] The water passage cavity 20 formed by the above-mentioned flushing mechanism forms a circle connected end to end along the side wall of the collection hopper b, and the water passage cavity 20 is connected to the water tank 1 through at least one water pipe.

[0031] Furthermore, the outlet of the water tank 1 is equipped with an electric valve, which controls the rinsing interval and the time of each rinsing session. Alternatively, a manual valve or other device can be installed to control the drainage volume.

[0032] Meanwhile, several rectifier rings 5 ​​are installed inside the aforementioned water passage cavity 20. These rectifier rings 5 ​​are fixed to the side wall of the water passage cavity 20 by welding or other methods and do not contact the bottom wall of the water passage cavity 20 (i.e., the upper surface of the guide plate 3). A booster pump 6 is installed between the water tank 1 and the water passage cavity 20. By installing the rectifier rings 5, the speed at which water flows directly out of the outlet 21 can be slowed down, ensuring that when the water tank 1 supplies water to the flushing mechanism, the water flow can reach the entire water passage cavity 20, thereby ensuring that the bottom wall of the collection hopper b is flushed in all directions. The booster pump 6 ensures that the water flow has sufficient pressure for faster delivery into the water passage cavity 20. (It would be best to supplement the structural features of the rectifier rings 5, such as their shape and size, and provide their working principle.)

[0033] The aforementioned cover plate 2 is a U-shaped piece with its opening facing downwards. It can be made of metal to ensure structural strength and can be bolted to the side wall of the hopper b. The outer side of the guide plate 3 extends upwards to form a connecting plate 31 that seals against the outer side of the cover plate 2. Several screws 22 are provided on the inner side of the cover plate 2. The water outlet control plate 4 has waist holes 41 fitted onto the screws 22, with the length of the waist holes 41 aligned with the height. By adjusting the position of the screws 22 within the waist holes 41, the height of the water outlet control plate 4 can be adjusted, thereby adjusting the effective opening size of the water outlet 21.

[0034] Furthermore, the aforementioned guide plate 3 can be made of rubber, giving it a certain degree of elasticity, ensuring that it can be pressed tightly against the bottom wall of the hopper b by the pre-tightening force (of the cover plate 2), thereby achieving adaptive slope of the bottom wall of the hopper b.

[0035] A pressure plate 42 may also be provided on the lower edge of the aforementioned water outlet control plate 4; the pressure plate 42 is parallel to the bottom wall of the collection hopper b, or the slope of the pressure plate 42 is greater than the slope of the bottom wall of the collection hopper b. By setting the pressure plate 42, the water jets sprayed from the outlets 21 in all directions can be prevented from splashing upwards, so that the formed water curtain completely adheres to the bottom wall of the collection hopper b and flows downwards, thereby improving the flushing quality and efficiency.

[0036] Furthermore, the lower edge of the aforementioned guide plate 3 extends to the bottom of the pressure plate 42, and several guide grooves 32 are provided at intervals. The bottom wall of the guide groove 32 is a slope that connects the upper surface of the guide plate 3 and the bottom wall of the collection hopper b at both ends. Thus, even if the pressure plate 42 is completely lowered to fit the upper surface of the guide plate 3, the outlet 21 will not be completely closed; at the same time, the water flow sprayed from the outlet 21 will present several streams of water with small gaps to flush the collection hopper b, resulting in a better flushing effect.

[0037] The water tank 1 mentioned above is located above the belt c, that is, above the cleaning box a, and is installed on the bracket d of the cleaning box a.

[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
