Description

Movable jaw supporting mechanism of jaw crusher Technical Field The utility model relates to the technical field of crushers, in particular to a movable jaw supporting mechanism of a jaw crusher. Background The jaw crusher is also called jaw crusher for short, is mainly used for medium-granularity crushing of various ores and massive materials, and is widely applied to industries such as mines, smelting, building materials, roads, railways, water conservancy, chemical industry and the like. The application provides a mechanism for supporting the back side of a movable jaw, which is used for replacing the toggle plate, and is characterized in that the back side of the movable jaw is connected with an adjusting seat through the toggle plate, when an eccentric shaft drives the movable jaw to move, two ends of the toggle plate and the toggle plate seat arranged on the movable jaw and the adjusting seat rotate relatively to generate friction, and the toggle plate is worn seriously after long-time use. Disclosure of utility model The utility model aims to solve the technical problems and provides a movable jaw supporting mechanism of a jaw crusher. In order to solve the technical problems, the technical scheme is that the movable jaw supporting mechanism of the jaw crusher comprises an adjusting seat, wherein one side, close to a movable jaw, of the adjusting seat is provided with a middle plate, one side, far away from the adjusting seat, of the middle plate is provided with a supporting frame, and one side, far away from the middle plate, of the supporting frame is rotationally connected with a plurality of rollers. Preferably, a side of the adjusting seat away from the middle plate is provided with an inclined surface which is inclined in a direction away from the middle plate in a direction from bottom to top. Preferably, the middle plate is provided with a plurality of lightening holes. Preferably, the middle plate is detachably connected with the adjusting seat and the supporting frame respectively. Preferably, the both sides of intermediate lamella all are provided with the riser, be provided with a plurality of through-holes on the riser, all be provided with a plurality of screw holes on adjustment seat and the support frame. The jaw crusher has the beneficial effects that the adjusting seat is sequentially connected with the middle plate and the supporting frame, the supporting frame is rotationally connected with the plurality of rollers, after the supporting mechanism is arranged on the jaw crusher, the rollers play a role in supporting the back side of the movable jaw, and when the movable jaw and the rollers relatively move, the rollers passively rotate, so that the abrasion is small.
