一种放煤支架
摘要：
本发明实施例公开了一种放煤支架，所述放煤支架应用于综放工作面运输顺槽，能实现工作面运输顺槽端头超前支护和顺槽顶煤回收。所述放煤支架采用二架一组型式，在所述放煤支架的端头支架尾部设置尾梁插板。所述尾梁插板可以把所述放煤支架顶板上的金属网撕破，这样，工作面顺槽顶板的煤炭在矿压的作用下漏到所述转载机上，实现了对工作面运输顺槽顶部煤炭的回收。所述尾梁插板还可以在放煤结束后封堵放煤口，保证所述放煤支架能有效支护工作面运输顺槽顶板。
摘要（英）：

The invention discloses a coal-caving supporter which is applied to a fully-mechanized working surface transportation tailgate and can realize the advanced support of the ends of the working surface transportation tailgate and the recovery of top coal of the working surface transportation tailgate. The coal-caving supporter adopts a two-supporter-one-group mode, the tail part of an end supporter of the coal-caving supporter is provided with a tail beam flashboard; the tail beam flashboard can tear up a metal net on a top plate of the coal-caving supporter so that coal of the top plate of the working surface transportation tailgate is leaked to a reversed loader under the action of mine pressure, thereby recovering the top coal of the working surface transportation tailgate; and the tail beam flashboard can also block a coal opening after coal caving is finished to ensure that the coal-caving supporter can effectively support the top plate of the working surface transportation tailgate.
