摘要： A mining machine, in the form of a ranging drum shearer has a ranging arm 11 pivotally mounted on at least one end of the body 10, of the shearer. The arm 11 carries a cutter drum and an associated transversely mounted electric motor 12 which drives the cutter drum of said arm. The electric motor is contained withln a transversely disposed cylindrical shroud 20 mounted on or integral with the ranging arm 11 and spaced longitudinally of the axis of rotation 14 of the ranging arm 11. The machine runs in both directions on a track 16 which has a conveyor 16A which runs in one direction. Therefore, when the machine is running in the direction opposite to that of the conveyor a coal sizer 18 and an associated transversely mounted electric motor 19 are spaced in advance of the leading end face of the body. The coal sizer 18 is carried by a mounting 23 which is pivotally connected to the body 10 on the ranging arm hinge 14 and has a two-part sleeve 24A, 24B which locates around the shroud 20 and is rotatable relative to the shroud. When the ranging arm 11 pivots up or down, the shroud also pivots but the coal sizer 18 is restrained to remain in a pre-set stationary position so that it can break large lumps of cut coal to a size which enables the lumps to pass along the conveyor 16A under the machine body 10. The coal sizer 18 is restrained from pivoting with the shroud by a position-control arm 30 which is pivotal on the machine body and extends longitudinally alongside the coal sizer. The control arm 30 can be pivoted by a hydraulic ram 33 to locate it in the pre-set position. The arm 30 has a keyway 31 into which locates a key 32 coaxial with the coal sizer. The key 32 pivots and slides along the keyway as the ranging arm pivots and the sleeve 24 rotates about the shroud 20 so that a distance 'L' between the axis of the coal sizer and the shroud remains constant. When the control arm 30 is pivoted to its lowermost position, the drum drive motor 12 can be removed, unobstructed, from the shroud 20.
摘要翻译：作为测距鼓式采煤机形式的采矿机具有可转动地安装在采煤机的主体10的至少一个端部上的测距臂11。臂11携带一个切割滚筒和一个相关的横向安装的电动机12，它驱动所述臂的切割滚筒。电动机包含在横向布置的圆柱形护罩20中，圆柱形护罩20安装在测距臂11上或与测距臂11一体并且与测距臂11的旋转轴线14纵向间隔开。机器在具有传送器的轨道16上沿两个方向运行 16A在一个方向上运行。因此，当机器以与传送机的方向相反的方向运行时，煤粒度分配器18和相关联的横向安装的电动机19在主体的前端面之前间隔开。煤分选器18由安装件23承载，该安装件在摇臂铰链14上枢转地连接到主体10并且具有围绕护罩20定位并且可相对于护罩旋转的两件式套筒24A，24B。当测距臂11向上或向下枢转时，护罩也枢转，但是煤分选机18被限制为保持在预设的静止位置，使得它能够将大块切割的煤破碎至能够使块体通过的尺寸输送机16A位于机体10的下方。通过位置控制臂30限制煤分选机18与护罩的枢转，所述位置控制臂30在机体上枢转并沿着煤分选机纵向延伸。控制臂30可以通过液压缸33枢转以将其定位在预设位置。臂30具有键槽31，定位与煤分选器同轴的键32的键槽31。随着测距臂枢转并且套筒24围绕护罩20旋转，钥匙32沿着键槽枢转并滑动，使得煤分选机的轴线与护罩之间的距离“L”保持恒定。当控制臂30枢转到其最低位置时，鼓驱动马达12可以从护罩20移除，无阻碍地移除。

摘要： La présente invention concerne une haveuse comportant un châssis (2), un moto-réducteur (20), un tambour d'abattage (4) décalé latéralement par rapport au châssis (2) de la haveuse et supporté à une extrémité d'un bras (3) articulé par son autre extrémité à une extrémité du moto-réducteur (20), ce bras (3) étant actionné par un vérin (21). Le bras (3) relié au moto-réducteur (20) et supportant le tambour (4) se prolonge latéralement par rapport au châssis (2) dans une direction d'avance de l'abattage, la direction du bras étant modifiable à l'aide du vérin de manière à permettre différentes hauteurs d'abattage sans que pratiquement le bras ne dépasse à l'arrière du châssis lors de l'abattage.
