AI Technical Summary
When conveying coal, existing scrapers lack limits on the feed scraper on the chain, resulting in large pieces of coal being wound between the chain and the sprocket, which can easily cause the chain and the sprocket to be disconnected, affecting the feeding effect and conveying stability.
A coal mining scraper model is designed, using limit components to cooperate with the scraper body. Through sliding and rotating limit parts, the scraper can be avoided skewed and the zipper is pulled, ensuring the stable connection between the chain and the sprocket. At the same time, cleaning components such as brush plates and cleaning wires are set up to clean coal blocks adhered to the scraper to improve the feeding effect.
Through the use of limit components, the chain and sprocket are effectively prevented from being disconnected, the equipment failure rate is reduced, and the working efficiency is improved; the use of cleaning components avoids the accumulation of coal on the scraper and improves the stability and efficiency of feeding.

[0031] The application of one aspect of this embodiment is as follows: when the device is in operation, the device is first powered on, and then the motor 18 is started.

Since both sides of the inner cavity of the shell 1 are slidably matched with the limiting components, the limiting components cooperate with the scraper body 11, so that the scraper body 11 drives the limiting components to slide when it moves, and the limiting components cooperate with the scraper body 11, ensuring that the scraper body 11 will not be skewed and then pull the chain 9 to cause it to fall off the sprocket 8, effectively preventing large pieces of coal from falling between the chain 9 and the sprocket 8 and causing the chain 9 to fall off, effectively reducing the equipment failure rate, and improving work efficiency. Through the cleaning component that is set, the cleaning component scrapes off the coal blocks adhered to the scraper body 11, thereby avoiding the feeding effect of the scraper body 11.
