一种刮板输送机自检测中部槽装置的检测方法，包括以下步骤：
(1)用天平称量出刮板试块39和衬板8在实验前的重量。
(2)将衬板8水平固定安装在短杆32上，将刮板试块39安装于刮板6的凹槽内并进行固定。
(3)启动伺服调速电动机一22及伺服调速电动机二29，通过调节变频器的频率调节挡板提升输送机2及水平输送机17的运行速度。
(4)在上料料斗1中加入足够的冲击煤料，启动伺服调速电机三16，使整个曲柄滑块机构运转，完成刮板6与衬板8在冲击工况下摩擦运动的模拟。通过拉压力传感器12测得冲击摩擦过程中的摩擦力，通过平面膜盒传感器7测得冲击摩擦过程中的冲击力。
(5)完成参数测量后，停止各伺服调速电机，结束试验，收集试验煤料，并分别用天平称量刮板试块39和衬板8在实验后的重量，就可以计算出冲击摩擦运动的磨损率。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
