Jaw crusher

Abstract

The invention provides a jaw crusher. The jaw crusher comprises a rack, a movable jaw, a fixed jaw, a toggle plate, a moving jaw, an outer spring seat, a pull rod, a spring and an inner spring seat, wherein the movable jaw is movably installed on the rack; the fixed jaw is fixedly installed on the rack; one end of the toggle plate is movably installed at one end of the movable jaw; the moving jaw is installed at one end of the movable jaw; the outer spring seat is installed on the rack; the pull rod is installed on the outer spring seat; the pull rod is sleeved with the spring; the inner spring seat is installed on the rack and arranged at one end of the pull rod. The jaw crusher has the advantages that the jaw crusher has deep crushing cavity and is free from dead zones, thus improving the feeding capacity and the yield; the jaw crusher has high ratio of crushing and uniform product granularity; a gasket type discharge hole adjusting device is reliable and convenient and has large range of adjustment, thus improving the flexibility of equipment; a lubricating system is safe and reliable and parts are convenient to change and have small maintenance workloads; the jaw crusher has a simple structure, operates reliably and is low in operating cost; the discharge hole adjusting range is large, so that the requirements of different users can be met; the jaw crusher has low noise and less dust.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a breaking hammer machine for crushing materials. Background technique [0002] In large production lines, mechanical equipment is often used to move raw materials from one location to another for subsequent processing and production. Due to the large amount of raw materials used in the production line, and due to the characteristics of the raw materials themselves, the raw materials need to be processed in the form of small pieces or granules when they are used, and the raw materials need to be in the form of large blocks or plates during the molding process. To facilitate storage, transportation and use, etc. Therefore, when this type of raw material is used, it needs to be crushed first, and then moved to the next production process. The existing crushing methods are usually manual crushing or continuous beating with a mechanical hammer to crush the raw materials, or use ...
