The invention discloses a minitype broken glass piece collecting device. The minitype broken glass piece collecting device comprises a body, the middle end of the top of the body is fixedly connectedwith a first motor box, the inner cavity of the first motor box is fixedly provided with a first motor, an output shaft of the first motor is fixedly connected with a
threaded rod, the outer surface of the
threaded rod is in threaded connection with a threaded sleeve, the bottom of the threaded sleeve is fixedly connected with a crushing plate, and the bottom of the crushing plate is fixedly connected with teeth. According to the minitype broken glass piece collecting device, by means of coordination of the first motor, the
threaded rod, the threaded sleeve, the crushing plate, the teeth and fixed plates, the effect of crushing is achieved; by means of the manner that the
tail ends of electric stretching and contracting rods are fixedly connected with squeezing plates, the effect of squeezing crushing is achieved; by means of coordination of auxiliary plates, a
grinding disc and a second motor, the effect of
grinding into
powder is achieved; and by means of the minitype broken glass piece collecting device, the problems that existing minitype broken glass pieces are concentrated in one place after being collected, in this way, land is occupied, and value generated by the broken glass pieces is further wasted are solved.
