Special sweeper for feeder

The utility model relates to the technical field of mining equipment, in particular to a special sweeper for a feeder, which is characterized in that a mounting seat is fixedly connected onto a base, a rotating plate is rotatably connected onto the mounting seat, a scraping plate is fixedly connected onto the rotating plate through a first sunk screw, a chute frame is fixedly connected onto the base, and a supporting mechanism is slidably connected onto the chute frame. The supporting mechanism is connected with the scraping plate through a second sunk screw, and the base is connected with a tensioning mechanism used for limiting the supporting mechanism. After the scraping plate is extruded by the heavy scale plate, the scraping plate drives the rotating plate to move downwards, the scraping plate extrudes the tensioning mechanism through the supporting mechanism, the tensioning mechanism generates elastic force after being pressed, and the elastic force generated by the tensioning mechanism pushes and press
