Rocking bar structure for adjusting jaw crusher

Abstract

The invention discloses a rocking bar structure for adjusting a jaw crusher, and belongs to the technical field of jaw crushers. The rocking bar structure for adjusting the jaw crusher comprises a crushing box, a left side fixed jaw plate is arranged on the left side in the crushing box, and the top of the crushing box is rotationally connected with an eccentric driving shaft. A movable block is rotationally connected to the surface of a connecting rod, a movable rocking bar is hinged to the bottom of the left side of the movable block, and a right side fixed jaw plate is hinged to the other side of the movable rocking bar, so that the connecting rod drives the movable rocking bar during reciprocating motion, then the right side fixed jaw plate is driven, a supporting rocking bar is hingedto the right side of the right side fixed jaw plate, and the other side of the supporting rocking bar is hinged to the crushing box, so that the supporting rocking bar can stabilize the movable block, the movable block runs relatively stably, and finally the device has the advantage that the rocking bars can actively drive a crushing jaw so as to enhance the crushing capacity of the device.

Description

Technical field [0001] The invention relates to the technical field of jaw crushers, and more specifically, to a rocker structure for jaw crusher adjustment. Background technique [0002] Jaw crusher is commonly known as jaw crusher, also known as tiger’s mouth. The crushing cavity is composed of two jaw plates, a movable jaw and a static jaw, which simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in mining, smelting, building materials, For the crushing of various ores and bulk materials in the highway, railway, water conservancy and chemical industries, the highest compressive strength of the crushed materials is 320Mpa. [0003] The jaw crusher mainly has a crushing effect on the material, and while crushing the material, it has a pushing effect on the material, so that the device is not easy to be blocked. However, in the actual use process, the traditional jaw crusher rocker mainly plays The role of support and b...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a rocker structure for adjusting the jaw crusher, which has the advantage that the rocker can actively drive the crushing jaw, thereby enhancing the crushing capacity of the device and solving the traditional The rocker of the jaw crusher mainly plays the role of support and buffer. When the crushing jaw is crushing materials, it drives the rocker to obtain momentum, but the rocker plays a role in reducing the force of the crushing jaw. The rocker cannot actively drive the crushing jaw to produce Crushing force, the problem that the crushing force of the device to the material is relatively not strong enough
