Embodiment Construction

[0012] exist figure 1 Among them, the discharge port adjustment device is installed on both sides of the jaw crusher body (1) through the support (2). After the locking sleeve (5) is removed, turn the nut (4) installed in the nut seat (3), so as to drive the screw rod (6) to enter or withdraw from the body of the jaw crusher.

[0013] exist figure 2 Among them, two wedge-shaped blocks (7) are installed inside the jaw crusher, and one side of each wedge-shaped block is connected to the screw (6) through a pin shaft. When the screw (6) enters or exits the body of the jaw crusher At the same time, the wedge-shaped block is also driven into or out of the jaw crusher body, so that the superimposed thickness of the two wedge-shaped blocks will increase or decrease, thereby changing the movable jaw (10) through the toggle plate seat (8) and the toggle plate (9). ) to achieve the purpose of changing the size of the discharge opening.

[0014] exist image 3 Among them, two wedge ...

Abstract

The invention relates to a jaw type crusher material discharge port stepless adjustment apparatus, wherein an overlay thickness of two completely same wedge shape blocks is changed to change the size of a material discharge port so as to achieve stepless adjustment of the material discharge port, and a hydraulic cylinder can be adopted to achieve automatic adjustment of the material discharge port, such that jaw type crusher material discharge port adjustment can achieve the optimal opening. In addition, operations have characteristics of convenience and labor saving.

Description

Technical field [0001] The invention belongs to the category of mineral processing machinery in mining machinery, and relates to an invention of a method for adjusting a discharge port of a jaw crusher used for coarse crushing in mineral processing machinery. Background technique [0002] The discharge opening adjustment device of the widely used jaw crusher is to increase or decrease the thickness of the backing plate, thereby reducing or increasing the discharge opening. With this adjustment device, the operator inserts or extracts steel backing plates of different thicknesses according to the required adjustment amount, and the operation is laborious; stepless adjustment cannot be realized, so it cannot be adjusted to the most suitable discharge port opening; the hydraulic system cannot be used to realize automatic adjustment. Adjustment to reduce the labor intensity of the operator. Contents of the invention [0003] In order to solve the problem that the discharge op...
