本文叙述了刨煤机工作机构在各种底板岩石和煤体研磨性条件下关于寿命的实验研究结果。将刨头底座和刨头支承的磨损值作为摩擦路程、底板和煤层研磨性指标及在刨头工作区内截煤阻力的函数,并揭示出其规律性和获得计算式。文中还提出了可以借助可更换支承靴提高工作机构可靠性的结构。 提高采出煤煤质的最有效方法是使用刨煤机。在1988年用刨煤机采出的煤(多半是无烟煤)约1.8千万吨。并且,采出煤的77.4％是由CO75、YCB—2、YCT—2M和YCT—2B拖钩刨完成的。在看到这类刨煤机优于
This paper describes the plow coal working mechanism in a variety of floor rock and coal grinding conditions on the life of experimental results. The wear value of the plow base and the plow head support is taken as a function of the friction distance, the index of abrasiveness of the base plate and the coal seam and the resistance of coal intercepting in the working area of the plow head, and its regularity and calculation formula are revealed. The article also proposed a structure that can improve the reliability of the working mechanism by using the replaceable supporting boots. The most effective way to improve coal quality is to use a plow. Approximately 18 million tons of coal (mostly anthracite coal) was plowed in 1988 by plows. Also, 77.4% of the recovered coal was mopped by CO75, YCB-2, YCT-2M and YCT-2B. After seeing this type of plow better than
