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.
In or for a mineral mining installation comprising a winning machine movable back and forth along a guide means of a drive chain located in a guide channel in the guide, said guide being arranged on the mineral face side of a longwall conveyor and having a slot leading from said guide channel and opening towards the mineral face, an improved coupling device for connecting the drive chain to the machine, comprising:
