摘要（英）：

The invention discloses an automatic speed regulating device for a variable-frequency scraper conveyor adopting a combined mining working face, and belongs to the field of mineral transportation equipment. The automatic speed regulating device comprises a PLC, a PLC communication expansion module and a communication bus signal isolating gate, wherein the PLC communication expansion module is inserted onto the PLC; and the communication bus signal isolating gate is connected to the PLC communication expansion module, and is equipped with a port of a combined mining working face centralized control system. The invention further provides an automatic speed regulating method for the variable-frequency scraper conveyer adopting the combined mining working face. The variable-frequency scraper conveyor can be guaranteed to stably and reliably operate, so that working performance and working efficiency of the whole machine are improved.
