Plough for underground extraction

摘要

The plough according to the invention has two blade flaps arranged one above the other at one end of its plough body. The blade flaps are equipped with push blades and at the same time form a continuous loading surface for loading the excavated material lying in the plough track. According to the invention, the two blade flaps are pivotable about parallel, preferably vertical, pivot axes and are at the same time coupled via a mechanical positive coupling to form a pivoting unit so that both blade flaps can only swing out together into the working position.
