Abstract

The invention discloses a novel material catapult device which integrates the belt transmission of a novel structure and a secondary mechanism of the gangue. A rotating tray is utilized to actuate a band conveyor and a catapult roller to swing, which can fill material to the whole cross section of the tunnel. The high-speed rotating of a catapult roller can throw the material fed by a belt upward to reach the top of the tunnel, which avoids that the top of the tunnel has a cavity during the filling process. An oscillating oil cylinder is utilized to actuate the catapult roller to swing left and right, which realizes the maximization of the filling area of the tunnel.

Description

technical field [0001] The invention relates to a gangue conveying device in the field of coal mine machinery, in particular to a projecting device used for conveying coal gangue when backfilling a mine roadway. Background technique [0002] A large amount of coal gangue will be produced in the coal mining process, and the current method for its treatment is to transport the gangue to the ground for stacking. Not only will it increase the transportation cost and take up a lot of cultivated land, but also the waste rock transported to the ground will pollute the environment when the wind and rain blow. In the mining process of coal mines, in order to prevent the subsidence of gobs below roads, villages, factories, etc., some load-bearing coal pillars are generally reserved, which also caused a huge waste of resources. Using coal gangue to fill the post-mining roadway is one of the effective methods to solve the above problems. [0003] In the process of using coal gangue to...
