Automatic round explosive screening device

The automatic round explosive screening device can achieve remote control and man-machine isolation. The device is mainly composed of a lifting air cylinder, an explosion-proof motor, a speed reducer, a lifting guide rail, a screening sealing cover, an eight-diagram-shaped stirring paddle, a copper screen and a copper receiving groove. The explosion-proof motor, the speed reducer and the screening sealing cover are lifted to the highest position through the lifting air cylinder, then explosives needing to be screened are poured into the copper screen, and then the explosion-proof motor, the speed reducer and the screening sealing cover are reset through the lifting air cylinder. The explosion-proof motor is started, the explosion-proof motor drives the eight-diagram-shaped stirring blades to rotate after being decelerated by the speed reducer, and bristle and cow leather arranged on the rotating blades form rubbing force on the explosives in the axial direction of the copper screen, so that the explosives ent
