Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, and particularly relates to a scraper conveyor capable of self-cleaning the inner wall of a chute. Background Art

[0002] In the coal mining industry, scraper conveyors are often used to transport the mined coal. A scraper conveyor is a conveyor that is powered by a hydraulic motor and uses a conveyor chain (i.e., a scraper chain) to tow a scraper to convey materials in a chute.

[0003] The commonly used scraper conveyors in the coal mining field are generally double-sided chain conveyors, that is, two conveyor chains are arranged in parallel along the conveying direction, the two conveyor chains are close to the side wall of the chute, and a scraper is installed between the two conveyor chains. Since the conveyor chain needs to continuously move in the scraper, a certain gap must be left between the conveyor chain and the side wall of the chute. During the transportation of coal in a coal mine, due to the collision and friction between materials, a large amount of rock powder will be scattered, and these rock powders are easily accumulated in the gap between the inner wall of the chute and the conveyor chain. After long-term accumulation, it is easy to cause problems such as the conveyor chain being stuck and broken, and the hydraulic motor being overloaded and damaged.

[0004] In the prior art, in order to prevent the rock powder from accumulating on the side wall of the chute and causing a failure of the scraper conveyor, it is necessary to stop the machine after the scraper conveyor has been running for a period of time, and manually clean the rock powder accumulated on the side wall of the chute. However, the space on the side wall of the chute is small, and there is a conveyor chain blocking, so the difficulty of manual cleaning is great; at the same time, frequent shutdown cleaning will lead to low work efficiency and long time consumption of coal transportation. Summary of the Utility Model

[0005] Aiming at the technical problems that in the operation of the existing scraper conveyor, rock powder is easily accumulated on the inner wall of the chute, which is likely to cause failures of the conveyor chain and the hydraulic motor, and frequent shutdowns are required to clean the inner wall, the utility model provides a scraper conveyor capable of self-cleaning the inner wall of the chute, which can sweep out the rock powder accumulated in the two inner walls during the operation of the scraper conveyor, avoid a large amount of rock powder accumulation in the chute, and does not require frequent shutdown cleaning, so as to improve the service life and working efficiency of the scraper conveyor.

[0006] The utility model provides a scraper conveyor capable of self-cleaning the inner wall of the chute, which includes a chute, two conveyor chains are arranged in parallel in the chute, and a self-cleaning device is installed between the two conveyor chains. The self-cleaning device includes a cleaning strip, and the length of the cleaning strip is greater than the distance between the two conveyor chains; both ends of the cleaning strip pass through the two conveyor chains respectively and are fixed on the conveyor chains.

[0007] Furthermore, the length of the cleaning strip is less than or equal to the distance between the two inner walls of the chute, and the length direction of the cleaning strip is perpendicular to the length direction of the conveyor chain.

[0008] Furthermore, the cleaning strip is fixed to the conveying chain through a fixing sleeve, which facilitates installation and disassembly.

[0009] Furthermore, the cleaning strip is an anchor cable or a steel wire rope. Both the anchor cable and the steel wire rope are made of flexible materials, which can avoid damaging the inner wall of the chute or the conveying chain during the cleaning process. At the same time, the anchor cable and the steel wire rope have high strength and long service life.

[0010] Furthermore, both ends of the cleaning strip passing through the conveying chain spread out to form a steel brush, which can meticulously clean the inner wall of the chute and improve the cleaning effect.

[0011] Furthermore, 2 - 3 groups of self - cleaning devices are installed between two conveying chains.

[0012] The beneficial effects of the present utility model are as follows:

[0013] For the scraper conveyor capable of self - cleaning the inner wall of the chute provided by the present utility model, a cleaning strip is installed between two conveying chains. Both ends of the cleaning strip pass through the two conveying chains respectively. During the operation of the scraper conveyor, the cleaning strip can run in the chute along with the conveying chain. Both ends of the cleaning strip can clean the two inner walls of the chute, sweep out the rock powder accumulated in the two inner walls, and avoid a large amount of rock powder accumulating in the inner wall of the chute. Furthermore, it can prevent problems such as the transportation chain being stuck and broken, and the hydraulic motor being damaged due to overload operation caused by the accumulation of rock powder. There is no need to frequently stop the machine to clean the rock powder accumulated on the inner wall of the scraper conveyor, which can improve the service life and working efficiency of the scraper conveyor.
