GUIDE SKID SHOE OF A THIN SEAM MINING MACHINE

摘要

The invention relates to a construction of a skid shoe of a cutting machine for thin seams which allows for adjustment of the range of height of cutting without the need to change cutting drums. The skid shoe (1) has an lug (Γ) which goes into a clamp (2) constituting an end of a beam (3) of the cutting machine body. The skid shoe (1) is connected with the beam (3) by means of a connector (4) which has in its central part a crank (9) going through the lug (Γ) of the skid shoe (1). Said connector (4) in its front part (5) from the wall side has an external groove (6) through which goes a lock (7) determining the position of the connector (4). In one preferable embodiment the skid shoe (1) has a divided lug (Γ), whereas in another embodiment the connector (4, 4') is divided and united by means of a connecting screw (15), going through a hole (14) in an axis (Oi) of the crank (9).
