Adverse feedback conveying system for working face of underground coal mine

Abstract

The invention relates to an adverse feedback conveying system for a working face of an underground coal mine, and a control method of the system. The adverse feedback conveying system includes a coal cutter, a scraper conveyer, a transferring machine, a crusher and a belt conveyor, and is characterized by further including a control box respectively connected with the belt conveyor, the crusher, the transferring machine and the scraper conveyer, a coal quantity detection device mounted on the transferring machine, and a coal cutter positioning device, wherein the coal quantity detection device is connected with the control box, so as to provide transported coal information of the transferring machine; the coal cutter positioning device is connected with the control box, so as to provide position and forward direction information of the coal cutter relative to the scraper conveyer. After the adoption of the conveying system and the control method provided by the invention, starting signals of the belt conveyor, the crusher, the transferring machine and the scraper conveyer can be sent sequentially through the control box, so that the pressing and slipping can be avoided, equipment wear and power loss during low-load operation of the equipment can be reduced, the coal cutting efficiency is improved, and the requirement for coal cutting on the working face can be met.

Description

technical field [0001] The invention relates to an inverse feedback conveying system and a control method for coal mine underground working face equipment. Background technique [0002] The working face conveying equipment used for underground mining in coal mines is basically designed with the power and capacity of the latter equipment being greater than that of the previous equipment, and after the equipment is turned on, it works at a constant speed regardless of the load. This not only increases the purchase cost of coal mine user equipment and unnecessary power consumption during equipment operation, but also reduces the efficiency of coal mining. The reason is that the situation of the working face is extremely complex, and many monitoring devices have poor adaptability, so it is difficult to collect the working information of the actual coal mining process of the working face, and then it is impossible to realize the precise control of the operating speed of the conve...

[0002] The working face conveying equipment used for underground mining in coal mines is basically designed with the power and capacity of the latter equipment being greater than that of the previous equipment, and after the equipment is turned on, it works at a constant speed regardless of the load. This not only increases the purchase cost of coal mine user equipment and unnecessary power consumption during equipment operation, but also reduces the efficiency of coal mining.

The reason is that the condition of the working face is extremely complex, and many monitoring devices have poor adaptability, so it is difficult to collect the actual working face coal mining process information, and thus it is impossible to accurately control the operating speed of the working face conveying equipment according to the load change
