Abstract
The invention discloses a self-cleaning vibrating screen. The self-cleaning vibrating screen comprises a lower screen body and a top cover installed at the top of the lower screen body. A sieve is arranged in the lower screen body, and a cavity below the sieve is a discharging cavity. The top cover is provided with a feed port, a discharge cylinder which is communicated with the discharging cavity is arranged at the bottom of the lower screen body, a vibration motor is arranged on the outer surface of the discharge cylinder, a rubber spring is further arranged on the outer surface of the lower screen body and a mesh plate used for containing rubber cleaning balls is fixed below the sieve. A large material outlet is formed in the lateral face of the top cover in the tangent line direction of the sieve. During work, the vibration motor is started, the sieve and the mesh plate start to vibrate, the rubber cleaning balls jump up and down to beat the sieve due to the fact that vibration force is exerted on the rubber cleaning balls, and therefore materials accumulated on the surface of the sieve are removed. The self-cleaning vibrating screen has the advantages that when the vibration screen works, the rubber cleaning balls beat the sieve upwards so that the materials cannot be accumulated on the surface of the sieve or block meshes of the sieve, the seal-cleaning function is realized on the condition that machine halt is not needed, and the working efficiency is improved.
