Vibrating screen sand tray

Abstract

The invention discloses a vibrating screen sand tray, and belongs to the technical field of mining machinery. The vibrating screen sand tray comprises a vibrating frame, a vibrating device and a transmission device, wherein a screen net is mounted in the vibrating frame; side plates are arranged on the two sides of the vibrating frame; the vibrating device is arranged on the lower side of the vibrating frame, and the vibrating device comprises a transmission rod, a cam, and a row of ejector rods; a cross-shaped through hole is formed in the cam, the transmission rod comprises a cross-shaped rod and round rods, the round rods are arranged at the two ends of the cross-shaped rod correspondingly, and the transmission rod is mounted on the two side plates through the round rods; the cam is matched with the cross-shaped rod through the cross-shaped through hole; the two ends of a limiting plate are welded on the two side plates, and the row of ejector rods are arranged on the limiting plate; and a convex cap and an ejector plate are welded at the two ends of each ejector rod correspondingly, each convex cap is matched with each cam, and springs are arranged between the ejector plates and the screen net in a matched mode. According to the vibrating screen sand tray, the cam devices are used for conducting intensive vibration on the screen net, so that the vibration frequency of a vibrating screen is improved, and the vibration efficiency of the vibration screen is further increased.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to a vibrating screen sand table. Background technique [0002] At present, after mineral mining and grinding, due to insufficient grinding, it needs to be re-screened through a vibrating screen, while the traditional vibrating screen uses a vibrating frame to drive the screen to shake and screen. During the screening process, the sand will be screened together with the screen Shaking it up and down slows down the sifting. Contents of the invention [0003] The object of the present invention is to provide a vibrating sieve sand table, which intensively vibrates the sieve through a cam device to increase the vibration frequency of the vibrating sieve, thereby increasing the screening speed. [0004] In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: [0005] The present inventi...
