Definitions

  • the invention relates to a milling drum according to the type specified by the preamble of claim 1.
  • the invention also relates to a soil milling machine with at least one such milling drum.
  • Milling drums of the type in question are used to crush and/or remove soil material, in particular compacted or solid soil material, such as a concrete or tar surface. Such milling drums are often used to remove or partially remove a road surface (or the like). Such milling drums are known, for example, from the DE 698 24 340 T2 , the US 5,775,781 B and the DE 296 13 658 U known.
  • a disadvantage of the milling drums of the type in question known from the state of the art is that they are exposed to severe wear during milling operation, especially on the front sides of the drum base body (also known as the drum). Particularly when cornering with a relatively small curve radii (e.g. milling free manhole covers), there is severe abrasion on the front side of the drum on the inside of the curve due to the milling edge formed in the ground material. The abrasion is increased by an undercut in the ground material (so-called undercut) in relation to the milling edge. Attempts are currently being made to protect the front sides of the drum from excessive wear by attaching wear plates. However, this is only partially satisfactory.
  • a further disadvantage of the milling drums of the type in question known from the state of the art is that more milled material adheres to the milling drum box.
  • the invention is therefore based on the object of further developing a milling drum of the type in question in such a way that the frontal wear on the drum is reduced.
  • the milling drum according to the invention comprises a hollow cylindrical and axially extending drum base body, the so-called drum, which is defined with respect to its longitudinal axis by an inner drum radius and an outer drum radius.
  • Several milling chisels are attached to the outer peripheral surface or the lateral surface of the hollow cylindrical drum for Crushing and/or removing soil material.
  • two front-side milling chisels are arranged in the area of at least one circular end face of the hollow cylindrical bandage, which protrude from the relevant end face or protrude outwards from this end face and which, during milling operation, protect the relevant end face from direct abrasive contact with the soil material to be processed by the contact area or collision area between this end face of the hollow cylindrical bandage and the soil material being virtually cleared or cut free by these two front-side milling chisels.
  • the relevant end face of the hollow cylindrical bandage is thereby at least partially protected from abrasion, whereby excessive wear on the relevant end face, as well as on any chisel holders and weld seams on the relevant end face, is avoided or at least significantly reduced.
  • An essential aspect of the invention is the direct protection of the relevant front side of the hollow cylindrical drum by two front-side milling cutters, which is why the milling drum according to the invention is particularly suitable for cornering with a relatively small curve radius (e.g. milling free of manhole covers), despite the undercut on the milling edge.
  • a relatively small curve radius e.g. milling free of manhole covers
  • the two front-side milling cutters are arranged at equal intervals in a circumferential direction.
  • the first front-side milling chisel is arranged on at least one front side of the hollow cylindrical bandage in the radial direction (with respect to the longitudinal axis or the axis of rotation of the hollow cylindrical bandage) approximately centrally between the inner radius of the bandage and the outer radius of the bandage or between the inner circumferential surface and the outer circumferential surface of the hollow cylindrical bandage.
  • the cutting circle produced by this front-side milling chisel is located approximately centrally on the circular ring-shaped front side of the hollow cylindrical bandage.
  • the two front-side milling cutters are arranged directly in the bandage on the front side of the hollow cylindrical bandage.
  • the hollow cylindrical bandage is designed accordingly on the front side in question and has pockets, as explained in more detail below in connection with the figures.
  • the two front-side milling chisels arranged on the front side of the hollow cylindrical bandage are designed as replaceable milling chisels.
  • chisel change holders are arranged on the hollow cylindrical bandage, to which the replaceable front-side milling chisels are attached.
  • the axial longitudinal extension of the milling drum is greater than the (maximum) diameter of this milling drum.
  • the axial longitudinal extension is several times greater.
  • the axial longitudinal extension of the milling drum is smaller than the (maximum) diameter of this milling drum.
  • a milling drum can also be referred to as a milling rotor.
  • the solution to the problem also extends to a ground milling machine with a driver's platform (large milling machine), comprising at least one milling drum according to the invention.
  • a ground milling machine with a driver's platform large milling machine
  • This is in particular a road milling machine.
  • the solution to the problem also extends to a hand-held ground milling machine (compact milling machine), comprising at least one milling drum according to the invention.
  • a hand-held ground milling machine comprising at least one milling drum according to the invention.
  • This is in particular a road milling machine.
  • Fig. 1 shows a milling drum according to the invention, designated overall by 1.
  • the milling drum 1 includes a drum base body which is designed as a hollow cylindrical drum 2 and on whose outer circumferential surface or lateral surface 22 several milling chisels 3 and 4 are arranged for crushing and/or removing soil material.
  • the milling chisels 3 and 4 are, for example, replaceable milling chisels which are attached to the drum 2 by means of chisel change holders 31 and 41.
  • the chisel change holders 31 and 41 are in turn welded to the drum 2, for example.
  • the longitudinal axis of the milling drum 1 and the drum 2 is indicated by L.
  • the longitudinal axis L coincides with the axis of rotation.
  • the direction of rotation (or direction of revolution or milling direction) of the milling drum 1 for milling operation is indicated by D.
  • the milling chisels 3 are aligned with their milling chisel longitudinal axes essentially in the direction of rotation D, for example.
  • the milling chisels 3 can also be angled with respect to the direction of rotation D.
  • the left front side of the drum 2 is designated with 21.
  • the angled milling chisels 4, which protrude beyond the front side 21, serve to create a defined milling edge in the soil material to be worked. However, no protection for the front side 21 can be achieved using these milling chisels 4.
  • two front milling chisels 5a and 5b are arranged in the front area.
  • the front-side milling chisels 5a and 5b protrude beyond the left front side 21 by a defined amount x (e.g. several millimeters) and are intended to at least partially cut or clear the collision area between this front side 21 and the soil material to be processed during milling operation in order to prevent direct contact between the front side 21 and the soil material remaining during milling. essentially to avoid.
  • x e.g. several millimeters
  • the relevant collision area on the front side 21 is indicated as radial section T (which essentially corresponds to the thickness of the drum 2).
  • the front-side milling cutters 5a and 5b can cut free an area that exceeds this radial section T radially inwards and/or radially outwards.
  • the front milling cutters 5a and 5b are also designed as exchangeable milling cutters, which are attached to the drum 2 by means of cutter change holders 51.
  • the cutter change holders 51 are arranged in pockets 6a and 6b, as described below in connection with the Fig. 4
  • the front milling cutters 5a and 5b are angled at an angle ⁇ relative to the direction of rotation D or are inclined outwards relative to the plane of the left front side 21, as can be clearly seen from the illustration of the Fig. 1
  • the angle of attack ⁇ can be the same or different for both front-side milling cutters 5a and 5b. For milling drums with a large diameter or for milling drums with thick drums, more than the two front-side milling cutters may be required to clear the collision area.
  • Fig. 3 shows a plan view of the left front side 21 of the milling drum 1, according to the Fig. 1 viewing direction indicated by A.
  • the bandage 2 is defined by an inner circumferential surface with a bandage inner radius Ri and an outer circumferential surface 22 with a bandage outer radius Ra.
  • one drive disk 7 is present, which connects the bandage 2 to a rotary drive and/or to a suspension.
