The invention discloses a spraying linear vibrating screen comprising a screening box body. One side of the screening box body is fixedly provided with a mounting plate of which the upper surface is fixedly connected to a support rod, and the top end of the connecting rod is fixedly connected to a conveyor belt; the top of the screening box body is fixedly connected to a hopper of which one side is provided with a motor, and the output end of the motor is fixedly connected to a rotating shaft of which the outside surface is fixedly connected to a helical blade; and the bottom of the helical blade is provided with a cushion block fixedly connected to the inner bottom wall of the hopper, and the inner wall of the screening box body is fixedly connected to a screen. According to the linear vibrating screen, through arrangement of the mounting plate, the support rod, the conveyor belt, a guide plate, the hopper, the motor, the rotating shafts, the helical blade, the cushion block, a discharging port, the screen, a discharging hole, an excitation electromagnet, a gasket, a second spring, a vibration motor, a crude product discharging port and a finished product discharging port, the problems that the discharging port is liable to be blocked during discharging due to the limited diameter of the discharging port and the manual screening efficiency is low are solved.
