Description

Technical Field

[0001] The present application belongs to the technical field of coal mine engineering machinery, and specifically relates to a coal cleaning device and a scraper conveyor. Background Art

[0002] In the related art, during the production process of the fully-mechanized mining face, the tail of the scraper conveyor is usually in the tunnel and has a large gap with the coal wall. The remaining gap will cause coal piling during the production process, causing a large amount of floating coal to accumulate at the tail of the scraper conveyor. Excessive coal piling will make it difficult for the push bracket at the tail to push the scraper to move. Therefore, at least one worker per shift is required to perform continuous floating coal cleaning work during the production process. In addition, since the tail of the scraper conveyor of the fully-mechanized mining face is usually the return air chute of the working face, and the dust concentration of the return air chute is high and adjacent to the goaf, it will seriously affect the health of the workers who are cleaning the floating coal. During the mining process, the roof pressure is relatively large. During the production period, employees cleaning the floating coal at the tail of the machine are susceptible to the hazards of slabs and roof collapse, thereby causing personal injury. The labor intensity of workers cleaning the floating coal is high, and they need to pay attention to the conditions of the roadway, roof, gas, etc. at any time when cleaning the coal at the tail of the machine, which has many safety hazards. In addition, the underground conditions are poor, and it is difficult to have a chamber specifically for storing tools and small equipment accessories. Even if there is such a chamber, it is located far away from the working surface, which is inconvenient to use and greatly reduces the workers' equipment maintenance efficiency. Summary of the invention

[0003] The embodiments according to the present invention are intended to solve or improve at least one of the above technical problems.

[0004] One of the objectives of an embodiment of the present invention is to provide a coal cleaning device.

[0005] A second object of an embodiment of the present invention is to provide a scraper conveyor.

[0006] To achieve the first purpose of an embodiment of the present invention, a coal cleaning device is provided for a scraper conveyor, the scraper conveyor including a tail, and the coal cleaning device including: a base connected to the tail; a shielding cabinet connected to the base for shielding floating coal; and a coal cleaning plate provided at one end of the base away from the tail for cleaning floating coal.

[0007] In this technical solution, the base is connected to the tail so that the base can move synchronously with the tail. The shielding cabinet can be installed on the base by bolts, and a coal cleaning plate is provided at the front end of the base. When the coal cleaning device is used in the tunnel underground, the shielding cabinet is installed at the position of the tail facing the coal wall. As the coal mining proceeds, as shown in the figure, the shielding cabinet moves synchronously with the tail. The cabinet surface of the shielding cabinet close to the coal wall can block the floating coal from entering the tunnel. When the shielding cabinet moves along the direction of the scraper conveyor, the coal cleaning plate arranged at the end of the base away from the tail can clean the floating coal in the tunnel to the side of the working surface. Therefore, through the joint action of the shielding cabinet and the coal cleaning plate, the floating coal at the tail of the scraper conveyor can be automatically intercepted and cleaned without manual cleaning, which reduces the labor intensity and labor cost of the workers and avoids possible personal injuries caused by manual cleaning of floating coal.

[0008] In addition, the technical solution provided according to the embodiment of the present invention may also have the following additional technical features:
