Crushed stone transmission control system and method for mine exploitation based on radar detection

Abstract

The invention discloses a crushed stone transmission control system and method for mine exploitation based on radar detection. The crushed stone transmission control system comprises a plate feeder, alaser radar detector, a PLC control module and a background server, wherein the laser radar detector is arranged at the position, aligned with the plate feeder, of a machine opening, the laser radardetector is used for obtaining digital signals of outlines of stones on a conveying plate of the plate feeder through laser radar scanning and feeding back the digital signals to the background server, the background server is used for calculating the current proportion of large and small stones on the conveying plate according to the received digital signals, and the PLC control module is used for controlling a current value input into a motor of the plate feeder according to the calculated proportion of the large and small stones so as to control the frequency of the plate feeder for conveying the stones into a crusher. According to the system and the method, the function of the crusher can be exerted to the maximum extent, the conditions such as blockage of the crusher cannot be caused,full-automatic transmission of crushed stones of mining equipment is realized, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a radar detection-based gravel transmission control system and method for mining. Background technique [0002] In actual mining production, it is necessary to transport the mined large rocks to the crusher through a feeder (such as a vibrating feeder, etc.) for crushing operation. [0003] At present, most of the existing technologies control the feeding frequency of the feeder by manually setting the current value to ensure that the frequency of the feeder and the crusher are consistent. However, this method requires manual adjustment of the feeding frequency of the feeder in real time according to the crushing speed of the crusher. If the feeding is too fast, it will easily cause the crusher to block and may damage the equipment; if the feeding is too slow, it will also cause The idling of the crusher leads to the idle waste of the crusher and the low crushing efficiency.

However, this method requires manual adjustment of the feeding frequency of the feeder in real time according to the crushing speed of the crusher. If the feeding is too fast, it will easily cause the crusher to block and may damage the equipment; if the feeding is too slow, it will also cause The idling of the crusher leads to the idle waste of the crusher and the low crushing efficiency. Therefore, it requires a long-term manual on-duty, real-time adjustment of the set current value and then adjustment of the feeding frequency of the feeder, which requires high technical requirements for manual labor. The labor cost is high; moreover, due to the inevitable errors in manual operation or untimely feedback, the motor will be burned out due to high current, shortening the service life of the equipment, and thus increasing the cost of mining
