Sieve-pore-size-adjustable vibration sieve

Abstract

The invention discloses a sieve-pore-size-adjustable vibration sieve. The sieve-pore-size-adjustable vibration sieve comprises a vibration sieve shell and is characterized in that a frame is arrangedinside the vibration sieve shell, an upper screen is fixedly arranged in the frame, the bottom of the frame is fixedly connected with one end of an electric telescopic rod, the other end of the electric telescopic rod is fixedly connected with a fixing plate, a lower screen is arranged on the fixing plate in a lap joint manner and arranged right below the upper screen, a second magnet is fixedly arranged at the center of the bottom of the lower screen, a gear motor is fixedly arranged at the bottom of the vibration sieve shell, the output shaft of the gear motor is fixedly connected with the spindle of a second gear through a coupler, and the second gear meshes with a first gear. The sieve-pore-size-adjustable vibration sieve has the advantages that by the electric telescopic rod, the fixing plate, the gear motor, an air cylinder and support rods, the problems that friction between screens easily occur during the sieve pore size adjustment of a traditional vibration sieve, and a gap exists between the screens after the adjustment are solved.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, in particular to a vibrating screen with adjustable mesh size. Background technique [0002] The vibrating screen works by using the reciprocating rotary 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. The effect is to make the screen surface produce double-rotating vibration. Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. The size of the sieve holes cannot be adjusted. When different materials need to be screened, the screen can only be replaced, which is difficult to operate. Therefore, the present invention designs a vibrating screen with adjustable sieve size to solve the above problems. [000...
