Gypsum board wedge-shaped edge detection device

The utility model discloses a gypsum board wedge-shaped edge detection device which comprises a bottom plate, the upper end of the bottom plate is fixedly connected with a plurality of vertical plates, the upper end of the bottom plate is symmetrically and fixedly connected with two vertical rods, the upper ends of the two vertical rods are jointly and fixedly connected with a top plate, and the upper end of the top plate is provided with a fan. The telescopic ends of the two electric telescopic rods are jointly and fixedly connected with a mounting plate, and a cleaning mechanism is arranged below the mounting plate. The fan and the motor are started, after the motor is started, one rotating shaft can be driven to rotate, due to the fact that the first gear and the second gear are meshed with each other, the two rotating shafts rotate synchronously, and therefore the corresponding rotating plate and the corresponding brush layer are driven to rotate; the two brush layers rotate in opposite directions, the up
