Automatic Control System of Road Crusher

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 field of automatic detection technology, in particular to an automatic control system of a road stone crusher. Background technique [0002] Crusher is one of the main production equipment of mines, which covers a variety of industries such as metallurgy, non-ferrous metals, building materials, and chemicals. In recent years, many domestic and foreign manufacturers have continuously improved and perfected this type of equipment from the product structure, and achieved relatively good results, and have successively introduced many new products with high efficiency, reliability and energy saving. In comparison, due to the influence of the development level of automation, the domestic research on crusher control is relatively backward. The control and operation of these devices are almost entirely carried out manually. Therefore, it is necessary to automate these old equipment to achieve automatic control functions. [0003] The s...

Problems solved by technology

[0004] However, in actual production and application, the electrical control of the crusher only implements simple opening and necessary electrical protection. Generally, manual adjustment is used to control the processing capacity of the crusher, which makes it difficult for the crusher to work in the best state, resulting in Inefficient production and waste of energy
