a screening machine

Abstract

The invention discloses a screening machine. The screening machine comprises a fixed mounting plate (1), a power device (2), an upper tooth wheel (3), a fan-type tooth wheel (4), a rotary rod (5), a rotary bottom plate (6), an adjusting device and a bottom frame, the fixed mounting plate (1) is fixedly mounted on a fixed mounting rack, a balancing weight (102) is arranged in the bottom of the fixed mounting rack (101), the power device (2) is fixedly arranged at the upper end of the fixed mounting plate (1), the upper tooth wheel (3) is fixedly connected with the end of the power device (2), the rotary rod (5) is fixedly mounted at the midpoint of the fixed mounting plate (1), the fan-type tooth wheel (4) is movably mounted on the rotary rod (5) and engaged with the upper tooth wheel (3), and the rotary bottom plate (6) is in a fan shape and fixedly arranged on the lower portion of the fixed mounting plate (1). The screening machine is simple in overall structure, convenient to operate, capable of reducing cost, capable of reducing economic loss and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a screening machine. Background technique [0002] In industrial production, sand, gravel, crushed stone and other materials need to be pre-processed before they can be further used. Generally, the screening machine uses the relative movement between the bulk material and the screen surface to make some particles pass through the sieve holes, and sand, gravel, and crushed stone Materials such as materials are divided into different grades according to particle size. The existing screening machines include drum type and vibrating type. This type of screening machine is expensive and the particles are easy to block the screen holes of the screen. It is very troublesome to remove. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a screening machine. [0004] The technical solu...
