[0002] In the process of coal mining, it is necessary to first build tunnels and provide support. In the existing comprehensive excavation technology for coal mine tunnels, a combination of a tunnel boring machine and a belt conveyor is used to achieve the purpose of tunnel excavation.

[0003] The current supporting conveying equipment used for underground coal mine boring machines will have dust and particles on the surface of the conveyor belt after a long period of work, which will reduce the friction of the conveyor belt, make it easy for coal to fall to the outside of the conveying device, and too much dust will easily cause machine failure.

[0004] For example, the Chinese patent document of the prior art (application announcement number CN218663669U) is a supporting conveying device for a coal mine and a tunneling machine. The device can effectively avoid the splashing of coal and rock slag by allowing the coal and rock slag to enter the buffer box from the first conveying device, and then the buffer box will collect the coal and rock slag and further discharge it from the discharge port at the bottom of the buffer box to the second conveying device. The prior art has the following problems: the conveyor belt surface will be contaminated with dust and particles, resulting in a decrease in the friction of the conveyor belt, and the coal ore is easy to fall to the outside of the conveying device, and too much dust is easy to cause machine failure.

[0005] Therefore, in view of this situation, it is urgent to design and produce a supporting conveying equipment for underground coal mine tunneling machines to meet the needs of actual use. Utility Model Content

[0012] Preferably, a pump is connected to a side of the water pipe away from the first fixed plate, and a fixed end of the pump is fixedly connected to a water tank.

[0013] Preferably, a spray pipe is connected to the side of the water delivery pipe, a spray port is opened on the side of the spray pipe, and a first support plate is fixedly connected to the lower side of the conveying device body.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The supporting conveying equipment for the underground tunneling machine in a coal mine drives the third supporting plate and the fourth fixing plate to move through the telescopic rod, and brings the scraper into contact with the conveying device body to remove impurities. At the same time, the first motor is started to drive the first circular gear and the second circular gear to rotate, and the cleaning wheel is driven to rotate to clean the conveying device body. At the same time, the pump is started to spray water to the conveyor belt of the conveying device body through the water pipe, the spray pipe and the spray port to flush the dust and particles on the surface of the conveying device body. Then, the impurities are separated from the conveying device body by the rotation of the cleaning wheel and the scraper, so as to avoid the surface of the conveying device body being contaminated with dust and particles, resulting in reduced friction of the conveying device body and affecting coal transportation.
