门式刮板取料机俯仰递进和行走速度分析

摘要

The paper introduces the principle of gantry scraping reclaimers , analyzes the critical parameters affecting the production capacity of the reclaimer , puts forward that constant productivity requires the variable control of the pitch progression and travelling speed , and introduces the control mode of these three variables .%介绍门式刮板取料机的原理，分析了影响门式刮板取料机生产能力的关键参数，提出了实现恒定生产率必须对俯仰递进或行走速度进行变量控制的要求，并介绍了三种变量控制模式。
