1 埋刮板输送机存在的问题 从图1可以看出其问题所在: （1）其上、下道轨系用δ=6mm的扁铁制成,磨损速度 较快,运转仅1月就几乎磨光;　 　 （2）下道轨磨损后,刮板便与机壳底部直接接触,致使 底部机壳很快被磨透。 2 埋刮板机结构的改进措施 （1）去除原结构中的上、下道轨（图2）; （2）用16组托轮替代原结构的上道轨,既可起到承托 作用,又消除了原道轨磨损快的弊端; 1 buried scraper conveyor problems can be seen from Figure 1 can be the problem: (1) the upper and lower rail system with δ = 6mm flat iron made, wear faster, only a few months on the operation almost Polished; (2) wear the next track, the scraper will be in direct contact with the bottom of the chassis, resulting in the bottom of the chassis was quickly worn out. 2 buried scraper machine structure improvement measures (1) to remove the original structure of the upper and lower rail (Figure 2); (2) with 16 sets of roller instead of the original structure on the rail, can play a supporting role , But also eliminates the shortcomings of the original track wear fast;
