Abstract

The present invention describes a road finisher for laying a paving material, comprising a material bunker for paving material and a spray jet module. In order to increase the spray carrying capacity in a structurally simple manner, it is suggested that a reservoir unit comprising a spray reservoir and a paving material reservoir should be arranged in the material bunker.

Claims

1. A road finisher for laying a paving material comprising a material bunker for paving material and a spray jet module, and a reservoir unit comprising a spray reservoir and a paving material reservoir, the reservoir unit being secured in position in the material bunker such that it is adapted to be fixed and released,

wherein the paving material reservoir is configured as a hopper with a feed opening.

3. A road finisher according to claim 1, wherein the spray reservoir is provided on both sides of the paving material reservoir.

4. A road finisher according to claim 1, wherein the spray reservoir encompasses the paving material reservoir in a U-shape.

5. A road finisher according to claim 1, wherein the spray reservoir is implemented as an auxiliary tank to an existing main spray reservoir.

6. A road finisher according to claim 1, wherein the spray reservoir is provided with at least one of a heating unit and a pump unit.

7. A road finisher according to claim 5, wherein a pump unit fills the spray reservoir from a tank vehicle in a self-sucking operation.

8. A road finisher according to claim 1, wherein a connection is provided for filling the spray reservoir from a tank vehicle.

9. A road finisher according to claim 6, wherein a pump unit automatically supplies spray to the main spray reservoir from the spray reservoir via a control unit of the spray jet module.

10. A road finisher according to claim 1, wherein the spray reservoir is provided with a pump unit and a heating unit, and wherein a control unit is provided for controlling the pump unit and the heating unit.

11. A road finisher according to claim 10, wherein the control unit circulates the spray in the spray reservoir via the pump unit in a temperature-dependent manner.

12. A road finisher according to claim 1, wherein the spray reservoir is provided with a heating unit including temperature control means.
