Dynamics Analysis of a Three-Motor-Driven Scraper Conveyor
In response to the considerable fluctuations in motor load observed in traditional scraper conveyors employing dual-motor propulsion at both the machine’s head and tail, we propose a novel three-motor drive configuration tailored explicitly for scraper conveyor systems.

Zhongguo youzhi为及时监测大豆预处理车间刮板输送机在生产中出现的断链、脱链等故障问题，保障刮板输送机的设备安全，分析了刮板输送机断链、脱链的故障原因，并提出了将刮板断链保护器应用于刮板输送机中。刮板断链保护器由速度传感器与信号处理器组成，当刮板输送机出现断链、脱链故障时，速度传感器所传输的脉冲信号频率会下降，信号处理器通过检测脉冲信号频率快速有效地作出反应，快速停机并发出声光报警，保障设备和生产安全。断链保护器结构简单，安装方便，并且不影响刮板输送机的正常运行，适合应用于一些传统企业中。In order to ...

Markovskay model of mining mass movement on scraper conveyors
Вестник Харьковского национального автомобильно-дорожного университета, 2009 Markovskay model of movement of mining mass is proposed for abrasive wear estimation of scraper conveyors. Integral characteristics both of mining mass and of conveyor construction are used in general view.

Health Status Assessment of a Scraper Conveyor Mechanical System
Highlights in Science, Engineering and TechnologyA method leveraging cooperative game theory is proposed to determine the combined weights of the mechanical system of a scraper conveyor, with a particular mining face serving as the research object. Additionally, the immune principle is introduced to estimate the health status of the mechanical system.
