Problems solved by technology
[0004] During the research process of the present invention, the inventor found that the above-mentioned existing scraper conveyor, especially the scraper conveyor with an open chute and a closed tail, has the following technical defects: the above-mentioned scraper conveyor During the working process, or during the process of extending, shortening or moving the scraper conveyor, the chain is likely to fall off the track. If the chain falls off the track and enters the closed tail, the handling of the chain will be difficult and the operation time will be reduced. long, seriously affecting the normal work of the working face and reducing the production efficiency of the mine
Moreover, the chain that falls off the road is likely to cause the chain to break, and it is prone to chain injury accidents.

The invention discloses a chain feeding device and a scraper conveyor. The chain feeding device comprises a channel lifting block arranged on the lower portion of a chute of the scraper conveyor. The channel lifting block is provided with at least one supporting slope, and an included angle ranging from 5-15 degrees is arranged between the supporting slope of the channel lifting block and the bottom face of the chute. When a chain of the scraper conveyor falls into a channel, the chain can be led into a chain groove through the supporting slope of the channel lifting block, automatic chain feeding is achieved, chain feeding is easy, and production efficiency and safety of mining operation can be improved.
Description
technical field [0001] The invention relates to bulk material transportation technology, in particular to a chain-up device of a scraper conveyor. In addition, the present invention also relates to a scraper conveyor equipped with the above chain winding device. Background technique [0002] In the current coal mining face, the function of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine. Therefore, the scraper conveyor has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can keep running continuously, and the production can go on normally. Otherwise, the entire coal mining face will be in a state of shutdown, which will interrupt the entire coal mining production. [0003] Generally, the scraper conveyor mainly includes three parts: the head, the middle part and the tail part. According to the number and arrangement of chains, scraper conveyors can be divi...
