 实施方式
下面结合附图对本发明进行详细描述。
本发明的一种综采工作面顺槽柔性刮板转载机的具体实施例1：
本综采工作面顺槽柔性刮板转载机整体结构如图1-图3所示，主要由皮带自移机尾1、推移机构2、机头3、机尾11、转载机机身、破碎机构成，转载机机身中部槽之间通过第一哑铃销连接，破碎机设置在转载机机身上并且转载机机身分为位于破碎机两侧的爬坡段4和落地段10，落地段10位于巷道底部，爬坡段4一端与破碎机连接，另一端斜向上朝向机头3上抬。破碎机包括破碎机主体7、破碎机入口槽8和破碎机出口槽6，其中破碎机主体7与破碎机入口槽8、破碎机出口槽6之间分别通过内联哑铃销连接。落地段10位于破碎机入口槽8一侧，落地段10中部槽与破碎机入口槽8通过第三哑铃销连接，爬坡段4位于破碎机出口槽6一侧，爬坡段4中部槽与破碎机出口槽6通过第二哑铃销连接。
机头包括机头架和设置在机头架上、对转载机刮板链起到传动作用的机头链轮轴组15，同样的，机尾包括机尾架和设置在机头架上、对转载机刮板链起到传动作用的机尾链轮轴组12。机头架与爬坡段4中部槽通过第四哑铃销连接，机头3与皮带自移机尾1之间则连接有推移装置2，如图4-图6所示，皮带自移机尾两侧设有滑道13，机头架两侧设有机头支撑板14，爬坡段4中部槽两侧、机头架上的机头支撑板14均搭接在皮带自移机尾两侧的滑道13上，如图1所示的，在推移装置油缸16的驱动作用下，可使机头与转载机机身相对皮带自移机尾沿滑道13产生位移，为对位移路径进行限制，皮带自移机尾两侧还设有限位板17，使机头和转载机受到推移装置作用沿滑道直线滑动，转载机相对皮带自移机尾的最大推移行程为A。
本发明提供的综采工作面顺槽柔性刮板转载机，将转载机机身分为落地段与爬坡段并在落地段与爬坡段之间设有破碎机，其中转载机机身中部槽之间、爬坡段与机头之间、爬坡段与破碎机之间、落地段与破碎机之间均为哑铃销柔性连接结构，转载机机身、机头直接搭接在皮带自移机尾上，于推移装置作用下使机头与转载机机身相对皮带自移机尾产生直线移动，通过以上柔性连接方式，消除转载机机身与皮带自移机尾之间的高度间隔，显著降低转载机机头部位整体高度，在此基础上实现推移功能时不必考虑底板干涉问题，使转载机相对皮带自移机尾推移行程较大，从而提高采煤生产效率。
以上仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
