Abstract

A cold planer is provided. The cold planer includes an engine and an enclosure compartment for a milling rotor. The enclosure compartment includes a frame defining an opening of the enclosure compartment. The enclosure compartment includes a moldboard connected to the frame. The moldboard is configured to move vertically between a first position and a second position with respect to the frame. An interfacing arrangement includes a first pair of components carried by the frame and a second pair of components carried by the moldboard. The components of one of the first pair of components and the second pair of components have slanted edges. The first and second pairs of components are configured to allow a lateral movement of the moldboard when the moldboard is in the first position and to engage one another to prevent the lateral movement of the moldboard when the moldboard is in the second position.

First claim

What is claimed is:

1. A cold planer comprising:
an engine; and
an enclosure compartment for a milling rotor, the enclosure compartment comprising:
a frame defining an opening of the enclosure compartment;
a moldboard connected to the frame, wherein the moldboard is configured to move vertically between a first position and a second position with respect to the frame; and
an interfacing arrangement including a first pair of components carried by the frame and a second pair of components carried by the moldboard, the components of one of the first pair of components and the second pair of components having slanted edges, wherein the first and second pairs of components are configured to allow a lateral movement of the moldboard when the moldboard is in the first position and to engage one another to prevent the lateral movement of the moldboard when the moldboard is in the second position.

2. The cold planer of claim 1 , wherein each of the first pair of components and the second pair of components have slanted edges.

3. The cold planar of claim 1 , wherein a gap is created between the corresponding first pair and second pair of components when the moldboard is in the first position for allowing the lateral movement of the moldboard.

4. The cold planer of claim 1 , wherein the other of the first and second pair components includes a corresponding projection to selectively engage with the corresponding slanted edge.

5. The cold planer of claim 4 , wherein the projection has a circular shape.

6. The cold planer of claim 4 , wherein the projection has a rectangular shape.

7. The cold planer of claim 1 , wherein the interfacing arrangement is provided at an upper portion of the moldboard and distal from an opening edge of the moldboard.

8. The cold planer of claim 1 , wherein two or more of the interfacing arrangements are provided on the moldboard and frame respectively.

9. An enclosure compartment for a cold planer machine, the enclosure compartment comprising:
a frame defining an opening of the enclosure compartment;
a moldboard connected to the frame, wherein the moldboard is configured to move vertically between a first position and a second position with respect to the frame; and
an interfacing arrangement including a first pair of components carried by the frame and a second pair of components carried by the moldboard, the components of one of the first pair of components and the second pair of components having slanted edges, wherein the first and second pairs of components are configured to allow a lateral movement of the moldboard when the moldboard is in the first position and to engage one another to prevent the lateral movement of the moldboard when the moldboard is in the second position.

10. The enclosure compartment of claim 9 , wherein each of the first pair of components and the second pair of components have slanted edges.

11. The enclosure compartment of claim 9 , wherein a gap is created between the corresponding first pair and second pair of components when the moldboard is in the first position for allowing the lateral movement of the moldboard.

12. The enclosure compartment of claim 9 , wherein the other of the first and second pair components includes a corresponding projection to selectively engage with the corresponding slanted edge.

13. The enclosure compartment of claim 12 , wherein the projection has a circular shape.

14. The enclosure compartment of claim 12 , wherein the projection has a rectangular shape.

15. The enclosure compartment of claim 9 , wherein the interfacing arrangement is provided at an upper portion of the moldboard and distal from an opening edge of the moldboard.

16. A method for controlling a movement of a moldboard with respect to a frame of a cold planer machine, the method comprising:
providing an interfacing arrangement including a first pair of components carried by the frame and a second pair of components carried by the moldboard, the components of one of the first pair of components and the second pair of components having slanted edges;
operating the moldboard between a first position and a second position,
wherein the first and second pairs of components are configured to allow a lateral movement of the moldboard when the moldboard is in the first position, and
wherein the first and second pairs of components are configured to engage one another to prevent the lateral movement of the moldboard when the moldboard is in the second position.

17. The method of claim 16 further comprising:
creating a gap between the corresponding first pair and second pair of components when the moldboard is in the first position for allowing the lateral movement of the moldboard.

18. The method of claim 16 , wherein the other of the first and second pair components includes a corresponding projection to selectively engage with the corresponding slanted edge.

19. The method of claim 18 , wherein the projection has a circular shape.

20. The method of claim 18 , wherein the projection has a rectangular shape.
