由哈尔滨煤矿机械研究所设计的SGZ—730/220S型刮板输送机,已于2月26日在辽源煤机厂问世,并通过东煤公司主持的出厂评议。该刮板输送机适用于缓倾斜中厚煤层(1.6～3m)长壁后退式回采工作面。在煤层为2m左右时该机最大铺设长度可达230m。该机可与采煤机、单体支柱(或液压支架)、转载机、可伸缩皮带机配套,实现采、装、运、推移支护的机械(或综采机械化)。该机主要由输送机主机、采煤机导向装
The SGZ-730 / 220S scraper conveyor designed by Harbin Coal Mining Machinery Research Institute was launched on February 26 in Liaoyuan Coal-mining Machine Factory and passed the ex-factory review presided over by the East Coal Company. This scraper conveyor is suitable for longwall back-mining face with gently inclined medium thick seam (1.6 ~ 3m). When the coal seam is about 2m, the maximum laying length of this machine can reach 230m. This machine can be used with shearer, single prop (or hydraulic support), reloader and telescopic belt machine to realize the mining (or fully mechanized) mechanization of mining, loading, transporting and pushing. The main machine by the conveyor, shearer guide installed
