Soil compactor for compacting soil material and method for operating such a soil compactor

Abstract

A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26′) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).

1 . A soil compactor for compacting soil material, comprising at least one compactor roller which is rotatable on a compactor structure around a roller axis of rotation which is essentially orthogonal to a compactor longitudinal direction, furthermore comprising at least one marking unit carried on the compactor structure for applying marking material to soil material driven over by the soil compactor. 
     
     
         2 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit is carried on the compactor structure in a substantially immovable manner.   
     
     
         3 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit, which is carried on the compactor structure in a substantially immovable manner, is carried on a side edge region of the compactor structure.   
     
     
         4 . The soil compactor according to  claim 1 ,
 wherein an edge pressing unit is provided on the compactor structure in association with at least one side edge region.   
     
     
         5 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit is carried on the compactor structure in a movable manner.   
     
     
         6 . The soil compactor according to  claim 5 ,
 wherein at least one guide rail is provided on the compactor structure, and in that at least one marking unit movably carried on the compactor structure is movable along the at least one guide rail.   
     
     
         7 . The soil compactor according to  claim 6 ,
 wherein, in association with at least one marking unit movable along the at least one guide rail, a marking unit drive for moving the marking unit along the at least one guide rail is provided.   
     
     
         8 . The soil compactor according to  claim 6 ,
 wherein at least one guide rail extends substantially in the direction of the roller axis of rotation, and/or in that at least one guide rail is arranged following a compactor roller in the compactor longitudinal direction.   
     
     
         9 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit comprises a spray can containing liquid marking material.   
     
     
         10 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit comprises a spray head, and in that at least one marking material tank connected to the spray head for supplying liquid marking material is provided on the compactor structure.   
     
     
         11 . The soil compactor according to  claim 1 ,
 at least one marking unit is designed to apply a pre-marking to the soil material, and/or in that at least one marking unit is designed to apply a road marking to the soil material.   
     
     
         12 . The soil compactor according to  claim 1 ,
 wherein at least one marking unit is designed to apply marking material as an unrolling tape.   
     
     
         13 . The soil compactor according to wherein,
 wherein at least one marking unit is controlled by a control unit and is operable by outputting control commands from the control unit to dispense marking material.   
     
     
         14 . A method for operating a soil compactor according to  claim 1 , wherein when the soil compactor is moved over the soil material, at least one marking unit for applying marking material to the soil material is operated. 
     
     
         15 . The method according to  claim 14 ,
 wherein an edge pressing unit is provided on the compactor structure in association with at least one side edge region, and   wherein, when the edge pressing unit is operated to form an edge of the soil material driven over by the soil compactor, at least one marking unit is operated to apply marking material to the soil material as an edge marking.   
     
     
         16 . The method according to  claim 14 ,
 wherein at least one marking unit is designed to apply marking material as an unrolling tape, and   wherein when a marking unit is operated for applying marking material as an unrolling tape, the marking unit is arranged in front of at least one compactor roller in a direction of movement of the soil compactor.   
     
     
         17 . The method according to  claim 14 ,
 wherein, when at least one marking unit is operated for applying marking material for a pre-marking:
 a part of the pre-marking is created during one marking pass and another part of the pre-marking is created during a further marking pass, 
   and/or
 a part of the pre-marking is created by one marking unit and another part of the pre-marking is created by a further marking unit. 
   
     
     
         18 . The method according to  claim 14 ,
 wherein at least one marking unit for applying marking material to the soil material is operated based on position data representing a position of the soil compactor on the soil material and/or based on marking model data.
