Coarse aggregate screening device for mine filling

Abstract

The utility model discloses a coarse aggregate screening device for mine filling. The coarse aggregate screening device comprises a screening box. When the coarse aggregate screening device is used for screening coarse aggregate, the coarse aggregate falls to the highest position of the inclined screen mesh to be screened through the inclined guide plate, the vibrating motor and the screen mesh are used in cooperation to conduct vibrating screening on the coarse aggregate, and the screened coarse aggregate falls to the conveying frame at the bottom of the screening box to be conveyed. When a guide plate is worn and needs to be replaced and disassembled, a pulling disc is pulled forwards, the pulling disc drives a pulling column, a connecting plate and a fixing block to move outwards and drives a reset spring to stretch forwards, when the fixing block is not in contact with a fixing groove, the guide plate can be pulled out rightwards and replaced, and therefore the beneficial effect that screening is convenient is achieved. Through cooperative use of the guide assembly, the pulling unit and the reset fixing unit, coarse aggregate can be guided when falling into the screen, secondary screening is not needed, and the screening time of the coarse aggregate is shortened.
