清筛机扒碴工作原理的探讨和扒碴功率的确定

A Study for the Operation Principle of Harrowing Ballast by Railway Ballast Clearing Machine and the Determination of the Power of Harrowing Ballast

对清筛机的扒碴工作原理目前还研究不够,本文提出了剪切、冲击扒碴原理,导出了确定扒碴功率的公式.

The research for the principle of operation about harrowing ballast by railway ballast cleaning machine is far from enough at present.In this paper, the theory about shear and clash in harrowing ballast is suggested and the formulae for determining the power of harrowing ballast are deducted.
