摘要： In the plough pick arrangement according to the invention for mining ploughs or coal ploughs, the plough pick is held in the socket of a pick holder. On that side of the pick holder which is leading in the working direction of the plough pick a pick lead-through opening is provided through which the pick can be inserted by its shank until it reaches a rear stop and is retained by a securing device. The pick can be removed from the socket through the same opening, after the securing device has been released, when pick replacement is necessary. This makes it possible to insert the pick into and remove it from the pick holder, not from the working side, but from the front of the holder. The pick holder and the pick are preferably provided with co-operating bearing and guiding faces which are inclined at an oblique angle to a plane parallel with the working face so that the cutting bit of the pick moves away from the working face when the pick is removed.
