Abstract

An earth working machine (10), for example a road milling machine (10), recycler, stabilizer, or surface miner, having a propelling unit (22) and a machine frame (12) carried by the propelling unit (22), comprises a working apparatus (32) for earth working; an operator's platform (24), having an operating console (26) for controlling at least one functional device (32, 39) of the earth working machine (10), being provided on the machine frame (12). Provision is made according to the present invention that the earth working machine (10) comprises, in the region of the operator's platform (24), a seat mount arrangement (66) that is embodied to be brought into releasable mounting engagement with a counterpart mount arrangement (76) of an operating seat (62, 64).

First claim

The invention claimed is:

1. An earth working machine, comprising:
a propelling unit;
a machine frame carried by the propelling unit;
a working apparatus supported from the machine frame for earth working;
an operator's platform provided on the machine frame, the operator's platform including an operating console;
a seat mount arrangement located in a region of the operator's platform, the seat mount arrangement configured to be brought into releasable mounting engagement with a counterpart mount arrangement of an operating seat; and
a stowage mount arrangement located in the region of the operator's platform and configured to be brought into releasable mounting engagement with the counterpart mount arrangement of the operating seat, the stowage mount arrangement being located below a projecting region of the operating console so that when the operating seat is engaged with the stowage mount arrangement the operating seat is covered by the projecting region of the operating console.

2. The earth working machine of claim 1 , wherein:
the seat mount arrangement includes a mount arrangement having a mount configuration configured for mounting engagement with a counterpart mount configuration of the operating seat, the mount arrangement being connected to the machine frame movably relative to the machine frame, with interposition of a damping arrangement.

3. The earth working machine of claim 2 , wherein:
the seat mount arrangement further includes a fastening arrangement fastened onto the machine frame; and
the damping arrangement is included in the seat mount arrangement and connects the mount arrangement to the fastening arrangement such that the mount arrangement is movable relative to the fastening arrangement.

4. The earth working machine of claim 2 , wherein:
the mount configuration extends along and around a virtual mount axis, and the mount configuration tapers along the virtual mount axis.

5. The earth working machine of claim 4 , wherein:
the mount configuration conically tapers along the virtual mount axis.

6. The earth working machine of claim 1 , wherein:
the stowage mount arrangement includes a stowage arrangement having a stowage configuration configured for mounting engagement with a counterpart mounting configuration of the operating seat.

7. The earth working machine of claim 6 , wherein:
the stowage arrangement is rigidly connected to the machine frame.

8. The earth working machine of claim 6 , wherein:
the seat mount arrangement includes a mount arrangement having a mount configuration configured for mounting engagement with the counterpart mounting configuration of the operating seat; and
the stowage configuration and the mount configuration each comprise a configuration portion of identical conformation configured for mounting engagement with the counterpart mounting configuration of the operating seat.

9. The earth working machine of claim 1 , further comprising:
the seat mount arrangement including a mount arrangement having a mount configuration configured for mounting engagement with a counterpart mount configuration of the operating seat, the mount arrangement being connected to the machine frame movably relative to the machine frame, with interposition of a damping arrangement;
the operator's platform including an operator's platform floor, and a damping structure interposed between the operator's platform floor and the machine frame so that the operator's platform floor is vibrationally decoupled from the machine frame; and
the operator's platform floor including a seat mount opening passing through the operator's platform floor, the mount configuration being reachable from the operator's platform through the seat mount opening.

10. The earth working machine of claim 9 , wherein:
the stowage mount arrangement includes a stowage arrangement having a stowage configuration configured for mounting engagement with the counterpart mounting configuration of the operating seat; and
the operator's platform floor includes a stowage mount opening passing through the operator's platform floor, the stowage configuration being reachable from the operator's platform through the stowage mount opening.

11. The earth working machine of claim 1 , further comprising:
the operating seat, wherein the operating seat includes a seat shell, a seat post extending away from the seat shell along a seat post axis, and the counterpart mount arrangement configured for connection to the earth working machine;
wherein the counterpart mount arrangement includes a counterpart mount configuration extending along and around a counterpart mount axis, the counterpart mount configuration tapering along the counterpart mount axis so that the counterpart mount configuration can be brought into and out of mounting engagement with the seat mount arrangement.

12. The earth working machine of claim 11 , wherein:
the counterpart mount configuration is configured such that the counterpart mount configuration can be brought into and out of mounting engagement with the seat mount arrangement by insertion and removal, respectively.

13. The earth working machine of claim 11 , wherein:
the mount configuration extends along and around a virtual mount axis; and
the counterpart mount configuration is configured such that the counterpart mount configuration can be brought into and out of mounting engagement with the seat mount arrangement by insertion and removal, respectively, along a placement path collinear with the counterpart mount axis and parallel or collinear with the virtual mount axis.

14. An earth working machine, comprising:
a machine frame;
a plurality of ground engaging units for supporting the machine frame from a ground surface;
a working apparatus supported from the machine frame for earth working;
an operator's platform provided on the machine frame, the operator's platform including an operator's platform floor;
an operator's seat including a seat post having a post end;
a seat mount connected to the machine frame below the operator's platform floor and including a seat mount receptacle configured to receive the post end;
a stowage mount connected to the machine frame below the operator's platform floor and including a stowage mount receptacle configured to receive the post end; and
the operator's platform floor including a seat mount opening above the seat mount and a stowage mount opening above the stowage mount, the seat mount opening and the stowage mount opening being configured to allow passage of the seat post therethrough for engagement with the seat mount receptacle or the stowage mount receptacle located below the operator's platform floor, respectively, such that the seat post is not attached to the operator's platform floor.

15. The earth working machine of claim 14 , further comprising:
a seat mount damping element located between the seat mount and the machine frame; and
wherein the stowage mount is fixed to the machine frame.

16. The earth working machine of claim 14 , wherein:
the post end includes a tapered portion.

17. The earth working machine of claim 14 , wherein:
the post end is configured for releasable engagement with the seat mount receptacle or the stowage mount receptacle.

18. The earth working machine of claim 14 , further comprising:
a plurality of damping elements between the operator's platform and the machine frame.

19. The earth working machine of claim 14 , wherein:
the post end, the seat mount and the stowage mount are configured so that the post en
