Problems solved by technology

[0020] The biggest shortcoming of the existing compound pendulum jaw crusher is that, due to the complex motion trajectory at the bottom of the movable jaw plate 83, when crushing stones, the stone is not only squeezed by the bottom end of the movable jaw plate 83, but also Also subject to partial grinding and stripping, the movable jaw plate 83 is relatively easy to wear and has a short service life, and because the movable jaw plate 83 is not easy to replace, so how to increase the service life of the movable jaw plate is really needed by the industry

Abstract

The invention relates to an improved jaw breaker. The improved jaw breaker comprises a frame, a fixed jaw board, a transmission mechanism, a movable jaw assembly and a gap adjusting mechanism; and the transmission mechanism has an eccentric shaft, the top of the movable jaw assembly is sleeved on the eccentric shaft to pivot the movable jaw assembly to the eccentric shaft, the press block of the movable jaw assembly is positioned at the top of a movable jaw protection board, the fastening bolt of the movable jaw assembly is positioned above the eccentric shaft, and there is an angle of below 180DEG between the movable jaw protection board and the movable jaw board of the movable jaw assembly, so the motion locus of the bottom end of the movable jaw board can be improved, the production capability of the jaw breaker is raised, the fine powder proportion is reduced, the service life of the movable jaw board is prolonged, and the integral weight of the jaw breaker is reduced.

Description

technical field [0001] The invention relates to a crusher, especially a compound pendulum jaw crusher, which is a machine capable of crushing mined natural stones according to a certain size, and is widely used in metallurgy, mining, and building materials. , chemical, coal and other industries. Background technique [0002] Existing machinery for crushing stone materials, one of which is a compound pendulum jaw crusher, its basic structure is mainly composed of two jaw plates (movable jaw plate and fixed jaw plate). The movable jaw plate reciprocates periodically relative to the fixed jaw plate, sometimes approaching and sometimes moving away, so that the stones located between the movable jaw plate and the fixed jaw plate are crushed by extrusion, splitting and bending. Because of its simple structure, easy manufacture, reliable operation, convenient use and maintenance, etc., it is widely used in engineering circles. [0003] see Figure 6 As shown, it is a compound pen...
