Abstract

The invention provides a jaw crusher. The jaw crusher comprises a machine frame, a static jaw assembly, a movable jaw assembly and a pivoting support mechanism; the static jaw assembly is provided with a static jaw crushing surface and is fixedly connected with the machine frame; the movable jaw assembly is provided with a movable jaw crushing surface, and the upper part of the movable jaw assembly is pivotally connected to a driving crankshaft which is rotatably arranged on the machine frame; one end of the pivoting support mechanism is pivoted to the movable jaw assembly, and the other end of the the pivoting support mechanism is pivoted to a fixed position of the machine frame; the included angle between the connecting line of the pivoting axis of the driving crankshaft and the movable jaw assembly and the hinge point of the pivoting support mechanism on the movable jaw assembly and the connecting line of the two hinge points of the pivoting support mechanism is an obtuse angle; and when the pivoting axis of the driving crankshaft and the movable jaw assembly moves away from a hinge point of the pivoting support mechanism on the machine frame, the lower end of the movable jaw assembly is driven to move away from the fixed jaw assembly so as to expand a discharge port. The jaw crusher solves the problem that in the prior art, the mechanical structure is complex for improving the mobility of materials.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a jaw crusher. Background technique [0002] The jaw crusher is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. This kind of crusher is widely used in medium-sized crushing of various ores and bulk materials in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The static jaw plate is fixed on the frame, and the upper part of the movable jaw plate is pivotally connected to the drive crankshaft, and is installed on the frame in a reciprocating manner close to and away from the static jaw plate through the drive crankshaft. By cooperating with the pull rod connected between the static jaw and the frame, one end of the toggle plate is pivotally connected to the lower end of the movable jaw through the connectin...
