Cutting head, in particular for a partial advance working machine

摘要

Cutting heads for partial advance working machines which are equipped with chisels and water jets have pipelines which extend inside the cutting head, lead outward through bores through the body and are connected via water distributors to the central water feedline arranged in the drive shaft. In order to improve handling and ease of repair of the water conducting system, a ring-like pipeline which runs around the outermost edge (5) of the hollow body (2), is divided into sections (6) and is provided with bores (7) is provided as water distributor (4), fittings (10) with connection lines (9) leading to the jets (8) being provided on the bores (7) and a connection line (11) of each section (6) being connected to the water feedline (15).
