Screen plate provided with adjustable and replaceable screen holes and facilitating filtering

Abstract

The invention discloses a screen plate provided with adjustable and replaceable screen holes and facilitating filtering. The screen plate comprises a screen plate body, the screen plate body is composed of a frame, a fixed mesh screen and a movable mesh screen, wherein a plurality of mounting holes I are formed in the frame, groove holes I are formed in the two ends of the front side edge of the frame correspondingly, groove holes II are formed in the two ends of the rear side edge of the frame correspondingly, supporting shafts I are arranged at the two ends of one side of the bottom of the framework correspondingly, two ends of the other side of the bottom of the frame are correspondingly provided with supporting shafts II, the fixed mesh screen and the frame are connected through a conical fastening assembly in a cooperative mode, a screw hole I and a screw hole II are correspondingly formed in the two sides of the interior of the movable mesh screen in sequence, and the movable mesh screen and the frame are connected through a linkage mechanism in a cooperative mode. The screen plate has the beneficial effects that the sizes of the screen holes can be adjusted, the screening efficiency can be improved, and the situation that looseness between a bolt and a nut occurs when the screening work is carried out can be avoided.

Description

technical field [0001] The invention relates to the technical field of sieve plates, in particular to a sieve plate with adjustable and replaceable sieve holes for easy filtering. Background technique [0002] Patent No. 20172171592.9 discloses an adjustable sieve plate for a coal separator. The adjustment method is to adjust the size of the sieve plate sieve hole by installing and disassembling the sieve bars. Seriously affect work efficiency. The sieve plate is the main screening part of the vibrating screen. Its performance directly affects the processing capacity of the vibrating screen and the screening effect of materials. The existing sieve plate installation structure is generally connected by conventional bolts and nuts. This is easy to cause the bolts and nuts to loosen or even fall off due to vibration during work, which will affect the screening efficiency and even cause casualties. [0003] Aiming at the problems in the related technologies, no effective solu...
