活底矿车
摘要：
本实用新型涉及的一种活底矿车，主要用于煤炭运输，属矿山运输工具领域。活底矿车是在不改变箱式固定矿车外形尺寸的基础上，在车箱底部用折页将可翻转底板固定在车架上。当矿车进入翻滚笼翻转180°时，可翻转底板靠自重打开，将车箱底部的煤或矸石震动掉，当翻滚笼转动完毕复位后，可翻转底板靠自重闭合。
摘要（英）：

The utility model relates to a larry mine car which is mainly used for coal transportation and belongs to the field of mine transportation tools. The larry mine car does not change the outside dimension of a box type fixed mine car, and a reversible backplane at the carriage bottom is fixed to a frame by hinges. When the mine car enters a rolling cage and turnovers 180 DEG, the reversible backplane is opened by self weight, and therefore, coal or gangue which are positioned at the carriage bottom are fallen off by vibration. When the rolling cage resets after rotating, the reversible backplane is closed by self weight.
