Abstract

The invention discloses an automatic control system of a road crusher. The automatic control system comprises an on-site process control level, wherein the on-site process control level comprises a PLC (Programmable Logic Controller), a touch screen connected with the PLC, a crusher, a motor connected with the crusher, a displacement sensor, a temperature transmitter, a pressure transmitter, a power transmitter, a solenoid valve, a hydraulic system, a frequency converter and an ore feeding motor. The on-site process control level uses the PLC as a core controller, uses the touch screen as a man-machine interface, and uses the displacement sensor to detect an ore discharge port of the crusher, uses the temperature transmitter to detect the temperature of lubricating oil, uses the pressure transmitter to detect the pressure of an oil cylinder, and uses the power transmitter to detect the power of a drive motor, and the PLC outputs a certain control amount according to a control model on the basis of acquired data; the rotating speed of the ore feeding motor is adjusted by the frequency converter, and the size of the ore discharge port is adjusted by the solenoid valve of the hydraulic system, and finally, the control object that the power of a main motor is constant is achieved.

Description

technical field [0001] The invention relates to the technology in the field of automatic detection, in particular to an automatic control system for a road crusher. Background technique [0002] Crusher is one of the main production equipment in mines, it covers metallurgy, nonferrous metals, building materials, chemical industry and other industries. In recent years, many manufacturers at home and abroad have continuously improved and perfected this type of equipment in terms of product structure, and achieved relatively good results, and have successively launched many new products that are efficient, reliable, and energy-saving. In comparison, due to the influence of the development level of automation, domestic research on crusher control is relatively backward. The control and operation of these devices are almost all carried out manually. Therefore, it is necessary to carry out automatic transformation on these old equipment to realize the automatic control function....
