Mining vibrating screen

Abstract

The invention relates to the technical field of mining machinery, in particular to a mining vibrating screen which comprises an elastic supporting base, a vibrating box mechanism fixed to the elastic supporting base, a bearing frame mechanism, a movable screen assembly and a fixed screen assembly; the vibration box mechanism comprises a vibration box fixed on the elastic supporting seat and two vibration motors which are assembled at the top of the vibration box in parallel and are used for providing a vibration source; the movable screen assembly and the fixed screen assembly are both assembled on the bearing frame mechanism. According to the technical field of mining machinery, the screen mesh structure of an existing vibrating screen is improved and designed, so that the functions of actively cleaning blockage and reducing blockage can be realized when various conditions possibly causing blockage of the screen holes are encountered in the actual screening operation process; the negative effects that the screening effect and the screening efficiency are reduced and the screen is blocked and damaged due to the fact that screen holes are blocked in the screening process can be actively weakened to a certain degree.

Description

technical field [0001] The invention relates to the technical field of mining machinery, and specifically provides a mining vibrating screen. Background technique [0002] Mine vibrating screen, as the name implies, is a screening equipment used to screen ore and other materials. Mine vibrating screen can be divided into high-efficiency heavy-duty screen, self-centering vibrating screen, elliptical vibrating screen, dewatering screen, circular vibrating screen , banana sieve, linear vibrating screen, etc.; the present invention provides a mining vibrating screen, especially a linear mining vibrating screen, the linear vibrating screen mainly relies on two identical vibrating motors to do synchronous rotation in opposite Prompt the whole sieve machine to do linear motion to realize the function of sieving. [0003] Regardless of whether it is a mining vibrating screen or any other type of vibrating screen, the screen is an important part of the vibrating screen. The correct ...

Problems solved by technology

[0005] (3) There are more materials with sheet structure

Because there is a lot of mud in the stone, or when the stone needs to be washed with water, the fine-grained stone will be bonded to each other due to the intervention of water.

[0007] The above four situations are the main reasons for the blockage of the screen during actual screening, and most of them are unavoidable situations. However, the screen structure of the existing mining vibrating screen is basically a fixed structure. Therefore, when encountering the above problems, it is easier to cause blockage of the screen hole, and it is impossible to actively weaken the screening effect and efficiency reduction caused by the blockage of the screen hole during screening, as well as the negative impact of screen blockage and damage.
