Stone crushing mechanism

Abstract

The utility model mainly relates to stone processing technical field, concretely relates to a stone crushing mechanism, including the crushing box, the lower part of crushing box is the conical structure, and its top and bottom are equipped with the feed port and the discharge gate respectively, the inside of crushing box is sequentially provided from top to bottom: pre -crushing unit, it includes two extrusion plates driven and relatively removes along the horizontal direction, and the opposite side of two extrusion plates is integrally formed with a plurality of equal interval distribution's broken rack, the screening board is drivenly connected with the screening mechanism for driving it to reciprocating vibration along the horizontal direction, the main crushing unit includes two horizontal arrangement, and driven synchronous reverse rotation's crushing roller. Through broken rack, the stone is preliminarily broken, and the screening mechanism drives the horizontal vibration of screening board, and the small stone that meets the particle size falls into two crushing rollers between further and is ground into the particle of predetermined specification through the sieve hole, effectively prevents the crushing roller from being stuck, and improves the overall crushing efficiency.
