Adjuster for cutting horizon of coal plough - has vertical slider engaging projecting head of jib whose position is adjusted by pressure and counter pressure of slider

摘要

The slider (13) on the stacking side of a conveyor (1) engages the head (12) of the jib (9,11) and raises or lowers it. The plough blade (2) grips the underside of the conveyor in order to tilt it according to the position of the jib, which is adjusted by the pressure and counter pressure surfaces (29,30) of the slider and head (12). The pressure and counter pressure surfaces are correspondingly shaped convex (29) and concave (30) with a gap between them. The slider either acts either slidingly or rollingly and its height is greater than its width. ADVANTAGE - Compact but not excessively constrained.
