Rotor Box For A Ground Milling Machine Having A Guide Device For Milled Material And Ground Milling Machine Having Such A Rotor Box

Abstract

The present invention relates to a rotor box for a ground milling machine, in particular for a road milling machine or a trench milling machine, having at least one milling roller accommodated therein for loosening and/or removing soil material. It is provided that at least one guide device is arranged in the interior of the rotor box, which, in cooperation with the rotating milling roller causes a conveyance of the loosened milled material in the axial direction (L) of the milling roller or at least supports such a conveyance. The present invention also relates to a ground milling machine, in particular a road milling machine or trench milling machine, which has at least one such rotor box.

1 . A rotor box for a ground milling machine having at least one rotatable milling roller accommodated therein for loosening and/or removing soil material and an ejection opening to transport milled material out of the interior of the rotor box, comprising:
 at least one guide device arranged in the interior of the rotor box, which, in cooperation with the rotatable milling roller, causes a conveyance of the loosened milling material in an axial direction (L) of the milling roller or at least supports such a conveyance towards the ejection opening.   
     
     
         2 . A rotor box for a ground milling machine having at least one rotatable milling roller accommodated therein for loosening and/or removing soil material and an ejection opening to transport milled material out of the interior of the rotor box, comprising:
 at least one guide device arranged in the interior of the rotor box, which, in cooperation with the rotatable milling roller, causes a conveyance of the loosened milling material in an axial direction (L) of the milling roller or at least supports such a conveyance towards the ejection opening, and   wherein the guide device is formed by a plurality of guide plates which protrude from an inner wall of the rotor box in the direction of the milling roller.   
     
     
         3 . The rotor box according to  claim 2 ,
 wherein the guide plates are arranged diagonally in relation to the axial direction (L) of the milling roller.   
     
     
         4 . The rotor box according to  claim 2 ,
 wherein at least respective parts of the guide plates are arranged surface-parallel and have equal spacing to one another.   
     
     
         5 . The rotor box according to  claim 2 ,
 wherein the guide plates are implemented having identical contour in side view.   
     
     
         6 . The rotor box according to  claim 2 ,
 wherein each of the guide plates has at least one curved contour section facing toward the milling roller in side view.   
     
     
         7 . The rotor box according to  claim 2 ,
 wherein each of the guide plates has at least one linear contour section facing toward the milling roller in side view.   
     
     
         8 . The rotor box according to  claim 2 ,
 wherein the guide plates are arranged in two groups, the guide plates in the first group having an opposite orientation to the guide plates in the second group.   
     
     
         9 . The rotor box according to  claim 2 ,
 wherein the guide plates are arranged on the inner wall of the rotor box opposite to the ejection opening.   
     
     
         10 . A rotor box for a ground milling machine having at least one rotatable milling roller accommodated therein for loosening and/or removing soil material and an ejection opening to transport milled material out of an interior of the rotor box, comprising:
 at least one guide device arranged in the interior of the rotor box, which, in cooperation with the rotatable milling roller causes a conveyance of the loosened milling material in an axial direction (L) of the milling roller or at least supports such a conveyance towards the ejection opening,   wherein the guide device is formed by a plurality of guide plates which protrude from an inner wall of the rotor box in the direction of the milling roller,   and further wherein the milling roller has cutting chisels mounted thereon and at least one conveyor device in addition to the cutting chisels, which, when the milling roller is rotating, causes a conveyance of the detached milled material in an axial direction (L) of the milling roller or at least supports such a conveyance.   
     
     
         11 . The rotor box according to  claim 10 ,
 wherein the at least one conveyor device is a conveyor scoop having at least one conveyor surface, which is arranged together with the milling cutters on an outer shell of a roller main body of the milling roller.   
     
     
         12 . The rotor box according to  claim 11 ,
 wherein a plurality of conveyor scoops, which are arranged distributed in the peripheral direction and/or in the axial direction (L) on the outer shell of the roller main body.   
     
     
         13 . The rotor box according to  claim 11 ,
 wherein the conveyor scoops are arranged having identical or different orientation of their conveyor surface between adjacent milling cutter rows.   
     
     
         14 . The rotor box according to  claim 10 ,
 wherein the conveyor SCOOPS have conveyor surfaces, and further wherein the conveyor scoops have a different orientation in one defined longitudinal section of the milling roller than the conveyor surfaces of the remaining conveyor scoops.   
     
     
         15 . The rotor box according to one of preceding  claim 11 ,
 wherein at least one conveyor scoop has a conveyor surface which is oriented diagonally to the axial direction (L) of the milling roller towards the ejection opening.   
     
     
         16 . The rotor box according to  claim 11 ,
 wherein at least one conveyor scoop is also implemented as a thrower.   
     
     
         17 . A ground milling machine comprising at least one rotor box according to  claim 1 . 
     
     
         18 . The rotor box of  claim 10 ,
 wherein the ground milling machine comprises a road milling machine or a trench milling machine.
