摘要： A solid-filling coal mining feeding and conveying monitoring system, suitable for monitoring of a vertical feeding and conveying system in underground mine solid-filling mining. The monitoring system mainly consists of an industrial control computer, a PLC control box, an operating platform, a liquid crystal display, a color four-picture divider, two video optical receivers and loudspeakers, four cameras, uphole electronic belt scales, downhole electronic belt scales, a radar level meter, a coal level sensor, a vibration sensor, and various matching junction boxes and cables, the components being installed in positions such as a material field, a control room, upper and lower openings of a storage silo, and a gangue transportation lane. The system implements four main functions of a solid-filling material transportation and feeding process, the four main functions being status monitoring, a full silo alarm, centralized control, and recording and querying. The monitoring content of the system is comprehensive; operation of the system is simple; and the system is safe and reliable.

摘要： A mechanical rocker-arm type vertical feeding cushioning device, consisting of two identical cushioning units and a box body (7). The two cushioning units are respectively arranged with a certain height difference on the inner side of the box body (7). Each cushioning unit consists of a cushioning mechanism and a fixing hinge mechanism. The cushioning mechanism is composed of a cushioning plate (1), a spring (5) and a balance weight (6). The fixing hinge mechanism is composed of a hinge plate (2), a right angle circular rod (3) and an elastic limiting device (4). The cushioning plate (1) is fixed to the hinge plate (2) via connection holes and using bolts. The hinge plate (2) is welded to the right angle circular rod (3). The elastic limiting device (4) consists of two elastic limiting plates and a hollow iron ring in a welded manner. The right angle circular rod (3) is connected to the elastic limiting device (4) in a sleeved manner via the hollow iron ring of the elastic limiting device (4). An upper end of the spring (5) is connected to the right angle circular rod (3), and the balance weight (6) is suspended at a lower end of the spring (5). Material is fed to the cushioning plates via a feeding pipe, and falls down after being cushioned twice by the cushioning plates (1). The cushioning device repeatedly cushions and recovers under the joint effect of the cushioning plates (1) and the cushioning balances (6).
