The utility model relates to a continuous mining machine drum tilt settings, including roller arm, gear box, gear box and the drum mounted on the moving arm, and the arm mounting hole is arranged at the rear of the boom, which is characterized in that the movable arm has two inclined front, the whole arm show the \Y\ type; the drum has two sets of peripheral drum provided with cutting teeth, two sets of rollers are respectively arranged on the front end of the boom, and the two drum set up \people\ - shaped; a bolt hole is arranged in the movable arm, and a two gear box, gear box mounted on the moving the arm of the bolt hole in the bolt; connected by spindle bearing on the cylinder and the gear box, the gear box and the drum as a whole. The use of continuous mining machine drum tilt setting, cross section coal hole changes, is no longer available rectangular, so as to improve the compressive strength of coal hole, occurred in the case of the same width more resistant to caving and floor heave.
【技术实现步骤摘要】
一种滚筒倾斜设置的连采机
本技术涉及一种连采机,尤其是一种滚筒倾斜设置的连采机。
技术介绍
现有连采机的滚筒都是采用平行安装,即滚筒的轴线与连采机的运动方向垂直。用这样的连采机作为边帮采煤机的机头所采出的煤洞都是矩形的,连采机作为露天矿边帮采煤机的机头以后,由于露天煤矿较浅,煤层的顶底板比井工开采的煤层的顶底板较软,巷道的矩形截面坚固性较差,容易产生冒顶和底鼓现象,使边帮采煤机不能正常退出。为了增加煤洞的坚固性,需要通过改进现有连采机,使所挖煤洞的截面形状变为非矩形的。
技术实现思路
一种滚筒倾斜设置的连采机,包括滚筒、动臂、减速箱,其中滚筒和减速箱安装在动臂上,且在动臂的后部设置动臂安装孔,其特征在于:动臂有两个倾斜设置的前端,使得动臂整体呈现为“Y”型;所述滚筒有两套,滚筒的外周设置有切割齿,两套滚筒分别安装在动臂的前端,且两套滚筒成“人”字形;在动臂上设有螺栓孔,且设有两个减速箱,减速箱通过螺栓安装在动臂上的螺栓孔中;所述减速箱通过其上的轴承与滚筒的主轴相连,使减速箱与滚筒成为一体。进一步,也可以在动臂前部设置一个倾斜设置的前端,此时该连采机安装一套滚筒,在此情况下 ...
