In the process of return journey, a rolling support device is adopted to support the baffles at both ends of the feeding trough plate, which aims to reduce the running resistance and then reduce the power consumption of the equipment. The rolling support device usually adopts a sprocket support device. On the Apron Feeder Mining equipment, The sprocket is generally fixed by the upper and lower clamping shell structure, which is not convenient for disassembly and maintenance, and the fixing effect is not good, and the clamping shell structure is easy to wear and the cost is high. On the other hand, the sprocket has no retaining edge, and the baffles at both ends of the feeding groove plate are prone to slide left and right during the rolling process, resulting in unstable operation of the feeding groove plate and easy to slide out of the axle, resulting in equipment failure.
The problem to be solved by the utility model is to provide a sprocket support device of Apron Feeder Mining with stable operation, convenient disassembly and assembly and simple structure according to the shortcomings of the prior art. In order to solve the above technical problems, the utility model adopts the following technical scheme, a sprocket supporting device of Apron Feeder Mining, including a wheel frame, a wheel shaft and a sprocket supporting wheel for supporting the baffle plate, the sprocket supporting wheel is arranged on the wheel shaft, a ring guard is arranged around the end of the sprocket supporting wheel, and both ends of the wheel shaft are installed on the wheel frame through a clamp. Further, the clamping element is a U-shaped bolt, and the U-shaped bolt is inverted on the end of the wheel shaft and is firmly connected with the frame body. Further, a bearing is embedded between the sprocket and the wheel shaft, and both sides of the sprocket are provided with a through-cover. As preferred, the contact surface between the end of the axle and the wheel frame is flat.
Further, the wheel frame is two parallel and opposite channel steel. Compared with the prior art, the utility model adopts the method of fixing a wheel shaft by setting a clamp at the end, and the contact surface between the end of the wheel shaft and the wheel frame is flat, which has good fixing effect, convenient disassembly and assembly, and simpler structure; The ring baffle set at the end of the sprocket can effectively prevent the baffle of the return section of the feed groove plate of the feeder from sliding out of the sprocket, making the equipment run more stable and reliable.
The new Apron Feeder Mining sprocket support device comprises a wheel frame, a wheel shaft and a sprocket used to support the baffle plate, and the sprocket is arranged on the wheel shaft, the wheel frame is two parallel and opposite channel steel, both ends of the wheel shaft are installed on two channel steel through the bracket, the bracket is preferably shaped bolt, and the shaped bolt is inverted on the end of the wheel shaft. It is connected with the frame screw to fix the axle, which is convenient to disassemble. The contact surface between the end of the axle and the wheel frame is flat, so that it has better fixing effect and stability. A bearing is embedded between the sprocket and the wheel shaft, and the relative position of the sprocket and the bearing on the wheel shaft is fixed by a through cover on both sides of the sprocket, so that the sprocket 3 will not move left and right on the wheel shaft when rotating, affecting the normal operation of the feeder.
