摘要： A baseplate plow with a multipart baseplate including a middle baseplate part connected to a plow body and two outer baseplate parts connected movably to the middle baseplate part. Guide blocks at a packing-side end of each baseplate part guide the baseplate in chain guide channels. Two chain blocks for connecting the plow pull chain are formed on a push member which is inserted into a recess at the packing-side end of the middle baseplate part, the recess being delimited in each of two running directions of the baseplate plow by a block part including a guide block and a stop surface for the push member.

摘要： A holding device for a chain is proposed, particularly for a chain associated with a coal cutter and having links located in two mutually transverse planes. The holding device has a chain block having two portions formed with a recess and bounding a slot. The recess is dimensioned for receiving an end portion of one of the chain links which is located in one of the planes, and the slot is dimensioned for receiving the other chain link which is located in the other of the planes. The recess may be U-shaped, and the slot extends in the direction of elongation of the chain block. Supporting portions may be provided for supporting one of the chain links which is located in a horizontal plane. Means may be provided for fastening the horizontal chain link to the supporting portions. Two additional such portions may be provided in the same chain block, spaced from the first two portions in the direction of elongation of the chain block. The slots of the two pairs of portions may be formed as a common slot extending in the direction of elongation of the chain block and bounded between the above portions and the supporting portions.

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： A mineral mining installation composed of a mineral winning machine such as a plough guided for movement along a conveyor. The plough has a sword plate extending beneath the conveyor and guided at the side of the conveyor remote from the machine. This guidance is provided by guide members attached to the sword plate and secured to a drive chain used for moving the plough. Guard plates are attached to the side of the conveyor remote from the machine and U-shaped cover plates are in turn affixed to the guard plates with the aid of screws and spacers. The guide members and drive chain run in a guide channel defined between the guard plates and cover plates and beneath the spacers. Each guide member is elongate and has a transversely-extending recess in its upper face. A roller or wear resistant insert is accommodated in the recess and seats on a spigot therein. Wearresistant pads are also attached to the guide members. As the sword plate tilts the periphery of the roller or a wear-resistant pad attached to the inner face of the insert is allowed to engage on the guard plates.
