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 carried by the road finisher for paving material and a spray jet module, and a removable reservoir unit comprising a spray reservoir section and a paving material reservoir section, secured in position in the material bunker and adapted to be fixed and removable from the material bunker as a single unit,

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

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

3. A road finisher according to claim 1, wherein the spray reservoir section is of a U-shape and encompasses the paving material reservoir section.

4. A road finisher according to claim 1, wherein the spray reservoir section of the reservoir unit is implemented as an auxiliary tank to an existing main spray reservoir mounted on the road finisher.

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

6. A road finisher according to claim 4, further comprising a pump unit to fill the spray reservoir section of the reservoir unit from a tank vehicle in a self-sucking operation.

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

8. A road finisher according to claim 5, wherein a pump unit automatically supplies spray to a main spray reservoir from the spray reservoir section of the reservoir unit via a control unit of the spray jet module.

9. A road finisher according to claim 1, wherein the spray reservoir section of the reservoir unit further comprises a pump unit and a heating unit, and wherein a control unit is provided for controlling the pump unit and the heating unit.

10. A road finisher according to claim 9, wherein the control unit circulates the spray in the spray reservoir section of the reservoir unit via the pump unit in a temperature-dependent manner.

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