Problems solved by technology

Because the structural characteristics and stress intensity of soft rock are different from those of hard rock, the crushing mechanism of soft rock and hard rock is different. If the existing rock crusher is used to crush soft rock, it will inevitably lead to energy consumption. Disadvantages such as too large, huge difference in rock particle size after destruction, etc.

Abstract

The invention discloses an extruding and grinding type soft rock crusher, which belongs to the field of rock crushing equipment. It includes a frame combination plate, a vibrating crushing device A, a vibrating crushing device B, a vibrating crushing device C, a rotary extrusion crushing device A, a rotary extrusion crushing device B and a conical feeding port; Device B and vibrating lithotripsy device C have the same structure as vibrating lithotripsy device A, including metal coil spring A, guide column, metal coil spring B, guide sleeve and vibrating plate; Extrusion crushing device B has the same structure, including a rotating shaft bracket, an extruding rotating shaft, a synchronous gear, a sliding sleeve and a conical extruding plate. The invention is a simple and reasonable structure, adopts two modes of vibration and extrusion grinding to destroy soft rock, and has better crushing efficiency and crushing effect.

Description

technical field [0001] The invention mainly relates to the field of rock crushing equipment, in particular to an extrusion grinding type soft rock crusher. Background technique [0002] Rock crushers are widely used in engineering. The crushing force of existing rock crushers is mostly eccentric impact force, and the main crushing objects are hard rocks or medium hard rocks. Because the structural characteristics and stress intensity of soft rock are different from those of hard rock, the crushing mechanism of soft rock and hard rock is different. If the existing rock crusher is used to crush soft rock, it will inevitably lead to energy consumption. The disadvantages are too large, and the particle size of the rock after destruction varies greatly. Therefore, designing a crusher for soft rock crushing has certain application value. Contents of the invention [0003] The technical problem to be solved by the present invention is: Aiming at the technical problems existing ...
