Embodiment Construction

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] figure 1 An embodiment of a jaw crusher provided by the present invention is shown.

[0030] The jaw crusher includes a casing 3 that can be fixedly installed on the foundation. The housing 3 is provided with openings corresponding to the positions of the material feed port 7 and the discharge port, and covers the internal components as a whole, so as to play a role of protection and support. A frame 4, a static jaw assembly 2, a movable jaw assembly 1 and a drive assembly are arranged inside the casi...

Abstract

The invention provides a jaw crusher. The jaw crusher comprises a static jaw assembly, a dynamic jaw assembly, a driving assembly and a tremor structure, wherein the static jaw assembly is installed on a machine frame, the dynamic jaw assembly is arranged on the machine frame in a close and keeping away reciprocating moving mode relative to the static jaw assembly, a crushing cavity with a large upper part and a small lower part is formed between the static jaw assembly and the dynamic jaw assembly, the driving assembly is installed on the machine frame and is in driving connection with the dynamic jaw assembly, and the tremor structure is arranged between the static jaw assembly and an installed base. Due to the arrangement of the tremor structure, firstly, vibration generated from reciprocating moving of the dynamic jaw assembly is transformed into waggling of the static jaw assembly, flowing of materials in the crushing cavity is facilitated through moving of the static jaw assembly, occurring of a vehicle jamming phenomenon caused by overfilling of the materials is reduced, so that vibration energy generated by the dynamic jaw assembly is effectively used; and secondly, waggling of the static jaw assembly consumes the vibration energy, vibration of a machine shell is reduced, the difficulty degree of machine shell fixing is reduced, the problem that a machine shell fixing device is prone to being fatigued and damaged is solved, and the whole service life of the jaw crusher is prolonged.

Description

technical field [0001] The invention relates to the technical field of material crushing equipment, in particular to a jaw crusher. Background technique [0002] The jaw crusher has a crushing cavity composed of two jaw plates, the movable jaw and the static jaw. The materials falling into the crushing cavity are squeezed and crushed by the mutual approach and separation of the two jaw plates. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] The static jaw is fixed on the frame, and the movable jaw is pivotally connected to the drive crankshaft, and is installed on the frame in a reciprocating motion close to and away from the static jaw plate through the drive crankshaft. The power unit drives the drive crankshaft, and then drives the movable jaw to do periodic reciprocating motion relative to the static jaw, sometimes separating and sometimes ap...
