The utility model relates to an ore feeding device of a wet-type strong magnetic
concentrator, which comprises a bottom plate, a first fixing frame, a second fixing frame and a third fixing frame are sequentially arranged on the bottom plate, a fixing component is arranged at the top of the first fixing frame, a
belt conveyor is arranged on the second fixing frame, and baffle mechanisms are arranged on two sides of the
belt conveyor. A feeding
assembly is arranged on the third fixing frame; the fixing
assembly comprises a sliding rail arranged on the top face of the first fixing frame, a sliding block is arranged on the sliding rail in a sliding mode, a fixing base is connected to the sliding block and used for containing a feeding pipeline, one side of the sliding block is connected with a
piston rod of a first air cylinder, and the first air cylinder drives the sliding block to reciprocate along the sliding rail. According to the feeding device, the movable fixing
assembly is arranged to fix the feeding pipeline, so that the feeding pipeline can move back and forth along with the fixing base, and therefore it is guaranteed that mineral materials are evenly fed. And meanwhile, the feeding pipeline can be simply, conveniently and rapidly stabilized through the fixing seat, the sealing piece and the unlocking mechanism, and the
reciprocating motion stability of the feeding pipeline is improved.
