The invention discloses an iron ore concentrate recycling and discharging trolley which comprises a belt transmission mechanism, a trolley with a scraper hinged to the bottom, a set of front wheels rotationally connected to the bottom of the trolley in sequence, a magnetic roller with the two sides connected with the front wheels through the belt transmission mechanism and a set of rear wheels, and a guide inclined plate and a U-shaped support are erected below the scraper. A collecting box with a rack on one side is slidably connected to the inner side of the support along the vertical end of the support, and a spring is connected between the bottom of the collecting box and the bottom of the support. The upper end of the support is slidably connected with a cover plate with a telescopic bottom in the width direction of the support, and linkage rods are hinged to the side, close to the magnetic roller, of the cover plate and the two sides of the middle of the scraper. One side of the support is connected with a slider-crank mechanism with a slider hinged to the cover plate, and a gear is mounted at a hinge point formed by a crank of the slider-crank mechanism and one side of the collecting box. The other side of the collecting box is of a pressing type turning cover structure, and the interior of the bottom of the collecting box inclines downwards in the direction close to the other side of the collecting box. And the iron ore concentrate recycling and discharging efficiency is high, and the cost is low.
