Abrégé

The milling head (1), which has a rotation axis (x) and which serves for machining a pile head (80) of a pile (8) that comprises a pile core (81), a pile jacket (82) and a metal armouring (83) interposed therebetween, comprises a coupling device (13), which is connectable to a drive shaft (2) of a driving device, a central milling cutter (11), which comprises a plurality of central chisels (111) mounted on a lower side of an inner ring plate (112), and a ring milling cutter (12), which comprises a plurality of ring chisels (121) mounted on an lower side of an outer ring plate (122), which central milling cutter (11) and ring milling cutter (12) are connected to each other coaxially aligned with the rotation axis (x), and which outer ring plate (122) surrounds the inner ring plate (112) separated thereof by a middle circular ring area (kr2). According to the invention the inner ring plate (112) comprises at least one transfer opening (1120A, 1120B) leading from the lower side to the upper side of the inner ring plate (112), which transfer opening (1120A, 1120B) is adjoined on the lower side by a conveyor shovel (119A, 119B) projecting at least partially into a working area of the central chisels (111) and which transfer opening (1120A, 1120B) is adjoined on the upper side by a conveyor spiral (113A, 113B).

Abrégé

The invention relates to a milling head (1) which has a rotational axis (x) and is used for machining a pile head (80) of a pile (8) having a pile core (81), a pile casing (82) and a metal reinforcement (83) therebetween, the milling head comprising: a coupling device (13) which can be connected to a drive shaft (2) of a drive device; a central milling cutter (11) which has multiple central bits (111) mounted on the underside of an inner ring plate (112); and a milling cutter ring (12) which has multiple ring bits (121) mounted on the underside of an outer ring plate (122), the central milling cutter (11) and the milling cutter ring (12) being connected to each other and oriented coaxially with the rotational axis (x), the outer ring plate (122) surrounding the inner ring plate (112), separated therefrom by an average circular ring area (kr2). According to the invention, the inner ring plate (112) has at least one transfer opening (1120A, 1120B) which leads from the underside to the upper side of the inner ring plate (112) and is adjoined on the underside by a conveying blade (119A, 119B), which protrudes at least partially into a working region of the central bit (111), and on the upper side by a conveying screw (113A, 113B).
