提出了一种利用煤矸石直接填充采空巷道的煤矿专用矸石回填机。该机由切顶支撑、机座、转向工作台、抛射带式输送机以及可伸缩带式输送机五大部件组成。采用液压作为动力源,液压缸为动力执行元件,进行机械的移动和调偏,实现了其自动控制,使得矸石回填效率大大提高。此外,大大简化该矸石回填机的行走底盘,省去减速器等一系列的辅助部件,减少成本,提高了回填机的平稳性和机动性。
A special gangue backfilling machine for coal mine is proposed which uses coal gangue to directly fill goaf. The machine consists of cut top support, base, steering table, throwing belt conveyor and retractable belt conveyor composed of five components. Using hydraulic as the power source, the hydraulic cylinder as the power of the implementation of the components, the mechanical movement and offset, to achieve its automatic control, making waste rockfill efficiency greatly increased. In addition, greatly simplifying the chassis of the gangue backfill machine, eliminating the need for a series of reducer and other auxiliary components, reduce costs and improve the backfill machine’s stability and mobility.
