Jaw crusher

Abstract

The invention discloses a jaw crusher. The jaw crusher comprises a movable jaw body, a static jaw body, a shell, a driving flywheel, a driven flywheel, an eccentric shaft, a fixed shaft, a transmission mechanism and a driving device, wherein the shell is provided with a cavity with an upward opening, the movable jaw body is obliquely arranged in the cavity, the bottom of the movable jaw body is rotatably connected with the shell, the two sides in the cavity are rotatably connected with the driving flywheel and the driven flywheel correspondingly, the eccentric shaft is arranged between the driving flywheel and the driven flywheel, the two ends of the eccentric shaft are connected with the driving flywheel and the driven flywheel correspondingly, the driving device is connected with the driving flywheel and used for driving the driving flywheel to rotate, the rotating axis of the driving flywheel is parallel to the rotating axis of the movable jaw body, and the transmission mechanism isused for enabling the driving flywheel to drive the movable jaw body to crush materials, so that the technical problems in the prior art, for example, the structure is unstable due to recoil and pulling force generated by irregular movement of the movable jaw are solved.

Description

technical field [0001] The invention relates to the field of jaw crushers, in particular to a jaw crusher. Background technique [0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing cavity 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. 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] In the complex oscillating jaw crusher in the prior art, the upper end of the movable jaw is directly suspended on the eccentric shaft, and the eccentric shaft is set on the flywheel as the connecting rod of the crank linkage mechanism. The movement of the eccentric shaft is driven by the motor to rotate the flywheel and then The eccentric shaft is made to perform a circular motion, and the lower end of the m...

AI Technical Summary

Problems solved by technology

[0004] Because the movable jaw in the prior art works, its movement trajectory is an irregular ellipse, because the weight of the movable jaw is usually heavy, so during the movement of the movable jaw, it is affected by the inertia of the movable jaw, and the eccentric shaft and The hinged end of the bottom of the movable jaw will be subject to the recoil and pulling force generated when the movable jaw moves, which not only makes the whole structure unstable, but also increases the strength requirements of the whole structure, which increases the manufacturing cost in a disguised form. There are: Recoil and pulling forces generated by the irregular movement of the jaws lead to technical problems of structural instability
