摘要： A coal plough has an elongate plough body which is provided with cutters at each end. The plough body is supported at each of its two ends, by a flat narrow skid on a plate of a plough guide. The skids constitute wear-resistant members and are connected to the plough body in a readily replaceable manner. The skids are so shaped that they guide the plough in the lower zone of the plough guide, and establish connection between the plough and the plough drive chain.

摘要： A cutter bit assembly for a mining or tunnelling machine has a cutter shank detachably fitted into a socket of a holder. To secure the shank in position a piston is displaced to cause pressure fluid to flow into a working chamber and act on a piston at one end of a rod-like securing element. The element is forced against a surface of the shank to urge the shank about a pivot and this in turn thrusts rear support surfaces of the cutter and the holder together. To release the cutter the pressure fluid is relieved and spring force displaces the securing element away from the shank. In this released condition, the cutter can be swivelled about the pivot and withdrawn from the socket.
摘要翻译：用于采矿或隧道掘进机的切割刀组件具有可拆卸地装配到保持器的插座中的切割器柄。为了将柄固定在适当位置，活塞被移动以使压力流体流入工作室并且作用在杆状固定元件的一端处的活塞上。元件被迫靠在柄的表面上以围绕枢轴推动柄，这又将切割器和保持器的后支撑表面推在一起。为了释放切割器，释放压力流体，弹簧力使固定元件远离柄。在这种释放状态下，刀具可绕枢轴转动并从插座中取出。

摘要： A cutter-bit assembly employs an arcuate wedge to secure a cutter-bit within a pocket of a holder. The wedge fits into a tapered gap between complementary curved surfaces of the holder and the cutter-bit shank. A projecting insert carried by the shank mates with a serrated portion on the wedge. Contact is established between the wedge and the curved surfaces of the holder and the shank over outer regions separated by non-contacting clearances.

摘要： A coal wining plough in a longwall working employs adjustable floor cutters mounted on curved carriers displaced in guideways on the body of the plough. Wedges abut on the upper ends of the carriers and are moved by hydraulic piston and cylinder units to set the position of the floor cutters and define the cutting level adopted by the plough. The units are operated with the aid of valves which respond to an electronic control device. Command signals from a remote control station are transmitted as by a radio to the plough to set up the electronic control device. Sensors on the plough provide electrical signals representing the position of the interface between the coal face and the floor and these signals are transmitted back to the control station. In a control sequence the plough runs along the seam and the sensor(s) provide signals relayed to the control station which also receives signals representing the distance moved by and/or the position of the plough. On a succeeding run the control station provides the control of the leading floor cutter in accordance with a control program.
摘要翻译：长壁工作中的煤犁耕作采用可调式地板切割机，安装在犁体上的导轨上移动的弯曲载体上。楔子抵靠在托架的上端，并由液压活塞和气缸单元移动，以设定地板切割器的位置并确定犁所采用的切割级别。这些单元借助于响应于电子控制装置的阀操作。来自远程控制站的命令信号通过无线电发送到犁地以建立电子控制装置。犁上的传感器提供表示煤面和地面之间的界面位置的电信号，这些信号被传送回控制站。在控制顺序中，犁沿接缝运行，并且传感器提供中继到控制站的信号，该信号还接收代表犁的移动距离和/或位置的信号。在接下来的运行中，控制站根据控制程序提供领先的地板切割机的控制。

摘要： A mineral mining installation employs a scraper-chain conveyor constructed from individual pans joined end-to-end and a plough having a drive plate running beneath the conveyor and on a skid bed formed as a sub-frame structure on the floor of the working. The drive plate is connected via guide means to the haulage run of a chain in a lower guide passage at the side of the conveyor opposite to the plough. An upper guide passage accommodates the return run of the chain. The passages are defined by a guide structure fitted to the side walls of the pans and includes detachable covers which can be removed for access purposes. At least some of the covers are linked with the sub-frame structure with the aid of tongue-and-groove connections. These connections permit limited movement of the pans and guide structure relative to the sub-frame structure longitudinally of the conveyor and limited raising and tilting movements of the side walls of the pans opposite the machine and the covers relative to the sub-frame structure as the drive plate passes along the conveyor.

摘要： A coupling device for connecting a mineral mining machine, such as a plough, to a drive chain. The coupling device is intended to locate within a channel inside a slotted guide containing the drive chain. The device is composed of coaxial tubular members secured together axially. The inner tubular member supports a swivel-mounted shackle connecting with the chain and a rigidly-mounted shackle connecting with the machine. One or both tubular members are shaped or relieved at the end nearest the swivel shackle to provide a cleaning nose which forces dust or the like from the channel as the chain draws the machine along the guide. A lateral projection on the outer tubular member engages in the slot and co-operates with the nose to guide the material away through the slot.

摘要： Apparatus for controlling the position of a mineral winning machine, such as a plough, movable along a guide at the mineral face side of a scraper-chain conveyor employs a connector bracket at the goaf side of the conveyor to which a floor-engaging skid plate is pivotably linked. A beam extends from a roof support and is also pivotably connected to the skid plate remote from the conveyor. A pair of piston and cylinder units are pivotably connected at their upper ends to the bracket. One of the units is pivotably connected to the skid plate and the other is pivotably connected to the beam. By operating the units together the skid plate can be held against the floor over part or all of its lower face while the conveyor goaf side is raised or lowered accordingly.
