Description
Technical Field
The utility model belongs to breaker accessory field, concretely relates to swing jaw structure for breaker.
Background
Jaw crushers are commonly called as jaw crushers and are also called as tiger mouths. The crushing cavity is composed of two jaw plates of a movable jaw and a static jaw, and the two jaws of an animal are simulated to move so as to finish the crushing operation of the material. Jaw crushers are mainly used as coarse crushers and medium crushers in the departments of mines, building materials, capital constructions and the like.
The movable jaw is periodically reciprocated, away from and towards the fixed jaw. When the materials are separated, the materials enter the crushing cavity, and finished products are discharged from the lower part; when approaching, the material between the two jaws is squeezed, bent and split to be broken.
The working face of jaw board and jaw board is made into the profile of tooth structure mostly for stopping the resilience of material to current jaw breaker, but this kind of jaw breaker jaw board is mostly laid perpendicularly, jaw board and jaw board are moved and are mostly 20 degrees left and right included angles with deciding, consequently at jaw breaker operation in-process, can often produce the bounce-back when moving the jaw extrusion because of the appearance and the particle diameter of handling the material cause, especially when handling more square material, its bounce-back situation is more obvious, greatly influence jaw breaker's throughput.
Disclosure of Invention
The utility model aims at providing a structure sets up reasonable and suitability strong movable jaw structure for breaker.
The technical scheme for realizing the purpose of the utility model is that the movable jaw plate structure for the crusher comprises a protective plate and a fixed jaw plate fixed on the protective plate, wherein fixed jaw teeth are fixed on the side surface of the fixed jaw plate, a movable jaw plate is also arranged on the protective plate, movable jaw teeth are fixed on the side surface of the movable jaw plate, the middle part of the movable jaw plate is connected on the protective plate through a shaft rod, a vertical chute is fixed on the protective plate, an inclined side plate is fixed on the end part of the protective plate, the vertical chute is arranged between the inclined side plate and the movable jaw plate and is positioned below the shaft rod, a transmission screw rod is arranged in the vertical chute, a driving motor connected with the transmission screw rod is fixed on the protective plate, a sliding block connected with the transmission screw rod in a threaded manner is arranged in the vertical chute, and a bearing block is fixed on the front surface of the sliding block, the center of the bearing block is transversely fixed with a transverse through hole, a pressing rod is arranged in the transverse through hole, one end of the pressing rod is an inclined plane, the inclined plane of the pressing rod is pressed on the inclined side plate, and the other end of the pressing rod is pressed on the side face of the movable jaw plate.
A limiting lug is fixed at one end of the abutting rod, and a return spring is fixed between the limiting lug and the side face of the bearing block.
The inclination angle of the inclined side plate is 15-30 degrees, the stainless steel plate of the inclined side plate is fixed with a reset pressure spring between the top of the movable jaw plate and the inclined side plate.
The side of the inclined side plate is fixed with a guide sliding groove, and the inclined surface of the abutting-pressing rod is arranged in the guide sliding groove through a guide sliding block.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, the simple operation realizes moving the removal of jaw through the lift of slider simultaneously, and the jaw is decided in the cooperation and the crushing operation is realized, simultaneously through supporting the pressure of depression bar to also be favorable to preventing to move the effect that the rebound appears in the jaw, guaranteed broken stability and reliability, the suitability is strong and the practicality is good.
