Discharge port size detecting system of jaw crusher

Abstract

The invention relates to a discharge port size detecting system of a jaw crusher, and belongs to the sensing detection and signal processing transmission technology. The discharge port size detecting system of the jaw crusher comprises a front end sensor subsystem and a control and transmission subsystem; the front end sensor subsystem detects the wear extentsof a fixed jaw plate and a movable jaw plate of the jaw crusher through wear sensors, and outputs the wear extents in a wear signal mode; the wear signals are amplified, filtered and converted to send to the control and transmission subsystem; the control and transmission subsystem calculates the present discharge port size according to the delivery discharge port size and the received wear signals; and the present discharge port size is displayed on a field human-computer interface. The discharge port size detecting system of the jaw crusher can monitor the discharge port size in real time, can timely master the discharge port size information of the jaw crusher through the field human-computer interface or remote login, and guides operators to timely adjust the discharge port size when a discharge portincreases so as to guarantee the qualification of production technology.

Description

technical field [0001] The invention relates to sensing detection and signal processing and transmission technology, in particular to a detection system for the size of a discharge opening of 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] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), the vertical or upper end is slightly tilted and fixed on the front wall of the body, the other is the movable jaw plate (moving jaw), the position is inclined, Together with the fixed jaw plate, a crushing chamber wi...

Problems solved by technology

[0007] However, during the use of the crusher, the size of the discharge port adjusted at the factory will change due to the continuous wear of the fixed jaw plate 2 and the movable jaw plate 3 of the wearing parts, while the traditional means need to rely on continuous manual observation and on-site Judging by the experience of the operator is often inaccurate and lagging behind
