Abstract

一种采煤机截割刀具,由截齿、齿套、齿座和弹性挡圈组成,其截齿为圆锥形,由弹性挡圈固定在齿套孔内;齿座埋藏焊接在采煤机螺旋滚筒的叶片和端盘中;齿套由轴用弹性挡圈固定在齿座孔内。该刀具使用寿命长,煤炭块率高,齿座的焊接强度强,不易损坏脱落,提高了装煤效果。

Description

一种采煤机截割刀具
本实用新型属于刀具,具体涉及一种采煤机截割刀具。
在现有的采煤机上,截割刀具一般为镐型刀具,它由截齿、齿套和齿座组成,其齿套由弹性挡圈固定在齿座头部的尾端,截齿由弹性卡环固定在齿套内;其齿座头部伸出叶片,尾部焊接在叶片或端盘内,其不仅焊缝短,会造成齿座焊接强度低,易损坏的缺点,而且由于刀具伸出长度Lp过长,造成采煤机螺旋滚筒装煤效果不好。
本实用新型的目的任务是为了解决上述存在的问题,而提供一种新的采煤机截割刀具。
本实用新型是这样设计的:它由截齿、齿套、齿座和弹性挡圈组成,其截齿为圆锥形,由弹性挡圈固定在齿套孔内;齿座埋藏焊接在采煤机螺旋滚筒的叶片和端盘中;齿套是用于保护齿座的,由轴用弹性挡圈固定在齿座孔内。
本实用新型的优点是:圆锥形截齿在截割煤炭时磨损均匀,从而延长了截齿的使用寿命;可以减少螺旋滚筒上的截齿数量,提高了煤炭块率,减少了粉尘;另外由于齿座埋藏焊接在螺旋滚筒的叶片和端盘中,因而加长了齿座的焊缝,增强了齿座的焊接强度,保证了齿座不易损坏脱落;截齿的径向伸出长度减小,提高了采煤机螺旋滚筒的装煤效果;
下面结合附图详细说明本实用新型的结构:
附图1为本实用新型的剖面示意图。
附图2为图1的A向示意图。
其中,1、截齿2、齿套  3、齿座  4、弹性挡圈 5、采煤机螺旋滚筒叶片或端盘
截齿1为圆锥形,由弹性挡圈固定在齿套孔内;齿座埋藏焊接在采煤机螺旋滚筒的叶片和端盘中;齿套是用于保护齿座的,由轴用弹性挡圈固定在齿座孔内。
