摘要

The head has an inner rim (29), an outer rim (31), an engine (33) and an endless snail (35) for swiveling of a chute (20) around a vertical axle (A) with respect to a frame (27). The outer rim supports the chute, and the inner rim is fixedly attached at the frame, where the rims are swivelable with respect to each other. The engine and the endless snail shift the outer rim in rotation with respect to the inner rim. A hydraulic actuator is provided for changing length of the chute.
