The retractable belt conveyor is mainly used for the gateway transportation of fully mechanized coal mining, high-grade general mining or general general general mining face, and also can be used for roadway driving transportation. At the same time, it can also be used in other mines, chemical industry, metallurgy, ports and wharves and other occasions where the transportation distance changes. Its main feature is that the tail of the machine can move automatically with the advance of the working face, and its transportation distance can be extended or contracted. The structure of the conveyor is compact. It can be laid directly on the floor of the roadway or suspended on the roof of the roadway. The frame is light and convenient. The frame can be connected without bolts. The "e" shaped pin or elastic cylindrical pin is used for connection, so it is very convenient for disassembly and assembly. The conveyor belt adopts the whole core belt and is connected by mechanical joints. If the conveying capacity and transportation distance are large, the intermediate driving device can be equipped to meet the material conveying requirements. In addition to controllable soft start, power balance and automatic control of belt tension, it is equipped with strict monitoring, sensing system and reliable safety protection facilities. The belt conveyor can meet the safety requirements of coal mine and other special occasions. All operation, monitoring, safety, protection and other work of the whole conveyor are directly controlled by the microcomputer according to the pre programmed, which can meet the requirements of coal mine explosion-proof, and it is safe and reliable to use.

telescopic belt conveyor is mainly used for gateroad transportation on underground comprehensive mining, top-grade conventionalmining or general conventional mining face in coal mines, it can also be usedfor tunnel heading transportation, meanwhile, it can also be used for materialconveying in applications with variable transportation distance such as mines,chemical engineering, metallurgy, harbor, wharf, etc. Its main characteristiclies in the automatic movement of its tail along with the shift of mining faceand the ability of extension or contraction of its conveying distance. Theconveyor is of compact construction, can be directly laid on the bottom plateof gate road or suspended from the top plate of gate road without foundation,it has light frames, which are connected with “E”-shaped pins or elasticstraight pins instead of bolts, thus making both assembly and disassembly veryconvenient. The conveyor belt employs solid core belt, which is connected withmechanical joints. In case of comparatively big conveying capacity andconveying distance, it can be equipped with intermediate drive to meet therequirements for material conveying. Besides controllable soft start, powerequalization and automatic regulation and control of conveyor belt tension forits functions, it is especially provided with rigorous monitoring and sensorsystems and reliable safety protection facilities. This belt conveyor can meetthe safety requirements for special applications like coal mines, etc. Allworks like operation, monitoring, safety, protection, etc. on the entireconveyor are directly controlled by a microcomputer according to preprogrammedroutine, therefore, it can meet the requirements for explosion protection incoal mines and ensure safe and reliable operation.
