Coal plough

摘要

The invention relates to a plough with two plough bodies guided on a plough guide and a mountable bridge which overlaps these plough bodies and is intended as a support for pick groups heightening the plough. The mountable bridge is detachably connected to the plough bodies on the face side via a bolt-slot connection and on the rear side can be locked to the plough bodies via locking devices which consist of simple fork-like push-in lock bolts. In addition, the mountable bridge has in the centre area an attaching device for a supporting portal. This attaching device essentially consists of an undercut inserting pocket arranged on the mountable bridge and of a corresponding plate extension on the supporting portal, which plate extension is fastened in a positive-locking manner in the insertion pocket and is secured by means of a push-in pin or the like.
