Abstract

The present invention relates to a rotor hood for a milling apparatus, with a front hood part, a rear hood part and two side hood parts, the front and the rear hood part enclosing together with the two side hood parts a working space that is open at the bottom, further comprising a stripping device which is mounted on the rotor hood and which forms the rear lower edge of the rotor hood in the working direction. The present invention further relates to a construction machine with a milling apparatus and such a rotor hood and a method for operating a milling apparatus with a rotor hood.

First claim

What is claimed is:

1. A rotor hood for a milling apparatus for shielding a milling rotor outwards, comprising
a front hood part;
a rear hood part;
two side hood parts,
the front and rear hood parts enclosing together with the two side hood parts a working space that is open at the bottom for receiving the milling rotor;
a stripping device pivotably mounted on the rotor hood which forms the rear lower edge of the rotor hood in the working direction for smoothing the milled ground material;
a mixing flap comprising a solid plate and being mounted on the rear hood part that is movable within an adjustment range into the working space and that is mounted on the rotor hood separately from the stripping device so that it deflects ground material milled by the milling rotor toward the milling rotor during working operation;
wherein the rotor hood comprises an opening which is closeable by the mixing flap and which has an outer contour of the opening being circumferentially formed by the rotor hood so as to define an entirely closed periphery of the opening; and
further wherein the mixing flap is mounted on the rotor hood in such a way that it completely closes off the opening outwards when in a position in which it is maximally pivoted out of the working space.

2. A rotor hood according to claim 1 ,
wherein the mixing flap is arranged behind the milling rotor and in front of the stripping device in relation to the stream of milled ground material.

3. A rotor hood according to claim 1 ,
wherein an adjustment limit is provided that limits at least an adjustment movement into the working space and/or an adjustment movement out of the working space of the mixing flap.

4. A rotor hood according to claim 3 ,
wherein the adjustment limit comprises an inside stop, against which the mixing flap strikes in an adjustment movement out of the working space.

5. A rotor hood according to claim 1 ,
wherein the mixing flap is mounted on the rotor hood in such a way that, in a position in which it is pivoted maximally out of the working space, the mixing flap closes off an opening provided in the rotor hood outwards.

6. A rotor hood according to claim 5 ,
wherein the opening extends over a working width of the milling apparatus.

7. A rotor hood according to claim 1 ,
wherein the mixing flap is configured as one piece.

8. A rotor hood according to claim 1 ,
wherein the mixing flap extends over an entire working width of the milling apparatus.

9. A rotor hood according to claim 1 ,
wherein the mixing flap is continuously adjustable.

10. A rotor hood according to claim 1 ,
wherein a drive device is provided which is adapted to drive an adjustment of the mixing flap.

11. A construction machine comprising a rotor hood according to claim 1 .

12. A method for operating a milling apparatus with a rotor hood according to claim 1 , comprising controlling a mixing operation and/or a degree of milling by way of an adjustment of the mixing flap within the working space of the rotor hood.

13. A method for operating a milling apparatus according to claim 12 , comprising individually controlling adjusting positions of the mixing flap and the stripping device that is mounted and adjustable independently of the mixing flap.

14. A construction machine according to claim 11 , wherein the construction machine comprises a recycler.

15. A construction machine according to claim 11 , wherein the construction machine comprises a stabilizer.

16. A construction machine according to claim 11 , wherein the construction machine comprises a milling machine.
