A system and method for controlling gravel transmission in mining based on radar detection

Abstract

The application discloses a system and method for controlling crushed stone transmission in mining based on radar detection, including: a plate feeder, a laser radar detector located at the position where the mouth of the machine is aligned with the plate feeder, a PLC control module and Background server; Wherein, lidar detector, is used for obtaining the digital signal of the outline of the stone on the conveying plate of apron feeder by lidar scanning, and feeds it back to background server; Background server, is used for according to receiving The digital signal is used to calculate the proportion of large and small stones on the current conveying plate; the PLC control module is used to control the current value input to the motor of the apron feeder according to the calculated proportion of large and small stones to control the apron feeder. The frequency at which the feeder feeds stones into the crusher. The application can not only maximize the role of the crusher, but also not cause the jamming of the crusher, etc., realize the fully automatic transmission of crushed stones in mining equipment, improve work efficiency, and reduce costs.

Description

Technical field [0001] The present invention relates to the field of mine mining, and in particular, a gravel transmission control system and method for mine mining based on radar detection. Background technique [0002] In the actual mine mining production, it is necessary to transfer large stones to the crusher on the crusher by a gallery (such as a vibrating feeder, etc.). [0003] At present, most of the prior art is to control the feed frequency of the feeder by manually set the current value, ensuring the frequency of the feeder and the crusher. However, this way is required to adjust the feeder frequency of the feeder according to the crushing speed of the crusher. If the given is too fast, it is easy to cause the crusher to block, or it may damage the equipment; if it is too slow, it will cause Crushing machine, leading to the idle waste of the crusher, low crushing efficiency, so this requires artificial long-term values, real-time adjustment of the set current value to ...

Problems solved by technology

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
