Multilayer screening machine

Abstract

The invention mainly discloses a multilayer screening machine which comprises a first box, a second box, a first screen plate, a second screen plate and a third screen plate. The second box is positioned in the first box and connected with a first rotating device, the first screen plate, the second screen plate and the third screen plate are sequentially arranged in the second box from top to bottom, a stirring device is arranged in the second box and comprises a stirring rod, a stirring disk and a second rotating device, the stirring rod penetrates the second box and the first box and is connected with the second rotating device, the stirring disk is connected with the stirring rod and respectively positioned above the first screen plate, the second screen plate and the third screen plate, and combing teeth are arranged on the stirring disk. According to the multilayer screening machine, automatic multilayer screening is achieved by the aid of a plurality of screen plates, the screening machine is wide in screening range, the stirring device and the second box mutually and reversely rotate, screening of materials is accelerated, screening quality is improved, blocking of the screening machine is prevented, maintenance frequency is reduced, and the service life of the screening machine is prolonged.

Description

technical field [0001] The invention relates to a multi-layer screening machine. Background technique [0002] In the prior art, the screening machine is mainly used for screening soil sand and gravel, sorting garbage and sorting agricultural products to separate materials of different volumes. The most important thing in the screening machine is the sieve plate. There are several sieve plates in the screening machine. The sieve holes of each sieve plate are different in diameter. The discharge port is discharged. In the screening process, the general screening machine needs to use vibration motors for the sieve plates of different layers, and the vibration motor is used to drive the sieve plates to vibrate for screening, which requires a lot of equipment and high equipment costs. Once a failure occurs, it is difficult to repair, and the sieve plates The sieve holes of the screen are easy to be blocked, so that the material cannot pass through the sieve holes smoothly, and...
