Blockage clearing device for ore dressing vibrating screen mesh

Abstract

The invention relates to the technical field of ore dressing devices, and particularly discloses a blockage clearing device for an ore dressing vibrating screen mesh. The blockage clearing device is characterized in that the power end of a driving motor mounted on the two side walls of the rear end of a screen box is connected with a screw rod; the periphery of the screw rod is sleeved with a sliding block in a threaded manner; the two end faces of a blockage clearing roller transversely arranged below the screen mesh are respectively connected with shaft bodies; a sliding groove is formed in the positions, corresponding to the shaft bodies, of the two side walls of the screen box; ejector pins are slidably sleeved with slotted holes formed in the surface of the blockage clearing roller; springs are connected between the inner ends of the ejector pins and the inner ends of inner cavities of the slotted holes; the outer ends of the shaft bodies are rotationally connected with the inner side face of the sliding block; gears with which the positions, close to the outer ends, of the shaft bodies are sleeved are meshed and matched with racks on the two side walls of the screen box; a sealing part is connected to an inner cavity of the sliding groove; lock catch parts used for opening and closing the sealing part from the middle position are arranged at the front end and the rear end of each ring body rotationally connected to the position, corresponding to the sliding groove, of each shaft body in a sleeved mode respectively; the horizontal distances between the adjacent slotted holes and the adjacent screen holes are equal; and the arc length between the slotted holes is equal to the longitudinal clear distance of the screen holes. The problem that the work efficiency of screen mesh blockage clearing is low is solved.

Description

technical field [0001] The invention relates to the technical field of mineral processing devices, in particular to a plugging removal device for a screen of a mineral processing vibrating screen. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. According to the material running track of the vibrating screen, it can be divided into linear vibrating screen (linear vibrating screen machine) and circular vibrating screen. Vibrating screen is a screening machine widely used in coal and other industries for grading, washing, dehydration and de-intermediation of materials. Among them, the linear screen machine has been widely used for its advantages of high production efficiency, good c...
