Description

防止刮板运输机机尾反链回煤装置
本实用新型涉及一种防止刮板运输机机尾反链回煤装置,特别是适用于煤矿井上、下和水份较大的潮湿煤炭的刮板运输机运输。
现有的煤矿井上、下普遍使用刮板运输机,它的主要结构是由机头、中间槽和机尾组成,一般这种刮板运输机运送煤炭都有反链回煤问题,特别是煤炭含水份较大时,更容易反链回煤,造成机尾堆煤,巷道端头淤积煤泥,造成工作场地低矮,有时还会卡住板链,出现事故。
本实用新型的目的是为了克服上述现有技术中的不足之处,而提供一种安装在刮板运输机机尾上,使刮板底链拉上来的煤炭,再控制上链,随其运走,不至于堆积在机尾的防止刮板运输机机尾反链回煤装置。
本实用新型的目的是这样实现的:它包括外导向板、内导向板、左侧板和右侧板,外导向板呈曲线形板状,它绕机尾并与机尾底板端部连接,内导向板包围机尾轮轴并与刮板中板连接,左侧板和右侧板的下边分别与机尾两侧的支承板连接,上边分别与外导向板两侧连接。
本实用新型彻底克服了刮板运输机机尾反链回煤问题,避免了因反链回煤卡住板链造成事故的现象,由于结构简单合理,易于推广使用。
附图图面说明:
图1为本实用新型的结构示意图;
图2为本实用新型的结构俯视图;
图3为本实用新型的结构剖视图。
下面结合附图及实施例详述本实用新型:
参照图1、图2、图3,本实用新型的外导向板(1)是一种具有良好机械强度的曲线形状板材,有利于物料的良好的导向作用,它绕机尾并与刮板运输机机尾底板(3)端部连接在一起,外导向板(1)内侧镶嵌有超高分子量聚乙烯内衬(2),它可减少摩擦系数,而且不生锈光滑,内导向板(5)包围机尾轮轴(9)并与刮板中板(10)连接在一起,左侧板(4)和右侧板(6)下边分别与机尾两侧的支承板(8)、(7)连接,上边分别与外导向板(1)两侧连接,外导向板(1)、内导向板(5)、左侧板(4)、右侧板(6)及机尾支承板(7)、(8)组成一个封闭的环形腔体A,使刮板运输机的刮板在这个封闭腔体A内运动,保证下链回煤再拉到上链,不至于跑出刮板运输机。

Claims (2)
