刮板机新型刮板
本技术涉及刮板输送机,具体是一种刮板机新型刮板。
技术介绍
刮板输送机是煤矿井下应用非常广泛的运输设备,在煤炭生产中起着重要作用。井下矸石跳汰分选设备内部采用的也是刮板机,由于在矸石分选过程中会产生大量的煤泥,刮板机运行时阻力大。现有刮板机刮板采用的是中间部分为整体结构,两侧压紧块与链环连接部位采用上下分体结构,受刮板材质、现场维修条件、使用条件等因素影响,经常造成压紧块弯曲和折断,使刮板与传动链条脱离,掉落的刮板又经常卡住刮板机,因而影响了刮板机的正常运转。另外原设计刮板未考虑将水刮上来后对设备现场环境造成的影响,同时因水流失较多后会影响矸石分选效果,还要定期对跳汰箱体补充水,又增大了维护人员的工作量。
技术实现思路
本技术要解决的技术问题是提供一种刮板机新型刮板,该刮板结构简单,强度大,安装方便,故障率低,提高了矸石分选效率。为解决上述技术问题,本技术采用如下技术方案:一种刮板机新型刮板,包括上半体、下半体,所述的上半体置于下半体的上表面,上半体的上表面与下半体的下表面均设有凹槽,凹槽内相应位置均设有连接孔,上半体与下半体通过连接孔、螺栓连接,上半体与下半体的两端设有压链槽;上半体与下半体的凹槽设有泄水孔,泄水孔排出凹槽内的水。采用上述技术方案的本技术,与现有技术相比,其有益效果是:通过设置凹槽,将螺栓固定在凹槽内,可以防止螺栓超出刮板上下面,以免刮板运行中卡阻;通过在上半体与下半体的凹槽设置泄水孔,利用泄水孔可将凹槽内以及刮板刮上来的水流回箱体,一是可以减小水的耗费,避免水流失较多影响矸石分选效果,并减少了定期对跳汰箱体的补水,大大减少了了维 ...
