Material returning prevention feeding device of jaw crusher

Abstract

The invention relates to a material returning prevention feeding device of a jaw crusher. The material returning prevention feeding device comprises a shell, a material stirring cavity is formed in the shell, an opening is formed at the upper left end of the material stirring cavity, a baffle is arranged at the position of the opening and can open or close the opening, a rotating rod is arranged in the material stirring cavity, four material stirring plates are fixed to the rotating rod, and a rectangular cavity is formed in the shell; and two first sliding blocks alternately sliding left and right are arranged in the rectangular cavity, blocking rods are arranged on the first sliding blocks, when the two blocking rods slide left and right along with the first sliding blocks, the right ends of the two blocking rods can enter and exit from the material stirring cavity, a second sliding block is arranged at the upper ends of the two blocking rods, the right end of the second sliding block extends into the material stirring cavity, and when the second sliding block slides leftwards, the baffle can be driven to close the opening. The second sliding block does not break away from the material stirring cavity, the blocking rods cannot stretch out of the material stirring cavity, and when the two first sliding blocks slide to the position where the main view projections coincide, a first switch is pressed; and the two blocking rods alternately block the material stirring plates, it is ensured that a conveyor belt conducts timed and quantitative discharging on a crushing opening of the jaw crusher, and the material returning phenomenon is reduced.

Description

technical field [0001] The invention relates to the field of crusher feeding, in particular to a jaw crusher anti-return feeding device. Background technique [0002] Jaw crusher is widely used as a kind of crushing equipment. It consists of a movable jaw plate and a static jaw plate. The jaw plate motion simulation and two animal material crushing operations. During the operation of the material, the material does not The phenomenon of flying out from the feed port through extrusion is the return of material, and the reasons for the return of material in the jaw crusher are various problems; [0003] Since the jaw crusher usually uses a conveyor belt to feed materials, the materials on the conveyor belt are usually rough materials with large differences in shape and size, so the feeding volume of the conveyor belt cannot be guaranteed to be constant, and there will be a phenomenon that sometimes the feeding is too much and sometimes the feeding is insufficient: feeding Too...
