They are usually installed under the coal bunker to evenly unload the coal in the coal bunker onto other conveying equipment such as belt conveyors. The general structure of the reciprocating coal feeder includes a material box, at the bottom of which a movable bottom plate is slidingly arranged. The starting end of the movable bottom plate is driven by a crank-connecting rod mechanism and a driving device, so that the movable bottom plate performs reciprocating linear motion. After long-term use, it was found that reciprocating coal feeders generally have the following disadvantages: coal particles or coal gangue particles are easily entered into the sliding connection between the bottom of the material box and the movable bottom plate, resulting in rapid wear of the movable bottom plate and a short service life.
