Abstract

A cold planer can include a frame; an operator station coupled to the frame and including a monitor; a cutting rotor coupled to the frame, the cutting rotor configured to be lowered a selected distance into a surface to define a depth of cut; a conveyor to receive material from the cutting rotor; and a cutting rotor location indication system including: a camera coupled to the frame and oriented to show an area on a side of the frame; and a visual indicator system configured to receive a first image from the camera and display on the monitor a visual image of a location of a leading edge and a trailing edge of the cutting rotor relative to the surface.

First claim

What is claimed is:

1. A cold planer comprising:
a frame;
an operator station coupled to the frame and including a monitor;
a cutting rotor coupled to the frame, the cutting rotor configured to be lowered a selected distance into a surface to define a depth of cut;
a conveyor to receive material from the cutting rotor; and
a cutting rotor location indication system including:
a camera coupled to the frame and oriented to show an area on a side of the frame; and
a visual indicator system configured to receive a first image from the camera and display on the monitor a visual image of a location of a leading edge and a trailing edge of the cutting rotor relative to the surface, wherein the cutting rotor location indication system further includes a light bar coupled to the frame and configured to display a light where a length of the light is indicative of the leading edge and the trailing edge of the cutting rotor; and a controller configured to receive depth of cut information from a sensor on the frame; and wherein the controller is configured to change the length of the light displayed on the light bar depending on the depth of cut; and wherein the camera captures the first image of the light bar and sends the first image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

2. The cold planer of claim 1 , wherein the controller is configured to receive the first image from the camera, and to output a second image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

3. The cold planer of claim 2 , wherein the first image includes a view of the surface and a portion of a side of the cold planer proximate the cutting rotor.

4. The cold planer of claim 2 , wherein the visual image includes one or more lines displayed on the monitor.

5. The cold planer of claim 2 , wherein the visual image of the location of the leading edge and the trailing edge of the cutting rotor grows longer when the depth of cut increases.

6. The cold planer of claim 1 , wherein the cutting rotor location indication system further includes a light coupled to the frame and configured to shine a light indicative of the leading edge and trailing edge of the cutting rotor; and wherein the controller is configured to change the size of the light being shined depending on the depth of cut; and wherein the camera captures the first image of the light being shined and relays the first image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

7. The cold planer of claim 6 , wherein the light includes one or more lasers configured to display one or more lines of light on the surface proximate the cold planer or on the cold planer frame.

8. The cold planer of claim 1 , wherein the light bar is coupled to the frame proximate a side plate of a housing of the cutting rotor.

9. A milling machine comprising:
a frame;
an operator station coupled to the frame and including a monitor;
a cutting rotor coupled to the frame, the cutting rotor configured to be lowered a selected distance into a surface to define a depth of cut;
a cutting rotor location indication system including:
a camera coupled to the frame and oriented to show an area on a side of the frame; and
a visual indicator system configured to receive a first image from the camera and display on the monitor a visual image of a location of a leading edge and a trailing edge of the cutting rotor relative to the surface, wherein the first image includes a view of the surface adjacent the side of the frame and a portion of a side of the milling machine proximate the cutting rotor.

10. The milling machine of claim 9 , wherein the cutting rotor location indication system further includes a controller configured to receive the first image from the camera, and to receive depth of cut information from a sensor on the machine, and to output a second image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

11. The milling machine of claim 10 , wherein the visual image includes one or more lines displayed on the monitor.

12. The milling machine of claim 10 , wherein the visual image of the location of the leading edge and the trailing edge of the cutting rotor grows longer when the depth of cut increases.

13. The milling machine of claim 9 , wherein the cutting rotor location indication system further includes a light coupled to the frame and configured to shine a light indicative of the leading edge and trailing edge of the cutting rotor; and a controller configured to receive depth of cut information from a sensor on the frame; and wherein the controller is configured to change the size of the light being shined depending on the depth of cut; and wherein the camera captures the first image of the light being shined and relays the first image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

14. The milling machine of claim 13 , wherein light includes one or more lasers configured to display one or more lines of light on the surface proximate the milling machine or on the frame of the milling machine.

15. The milling machine of claim 9 , wherein the cutting rotor location indication system further includes a light bar coupled to the frame and configured display a light where a length of the light is indicative of the leading edge and the trailing edge of the cutting rotor; and a controller configured to receive depth of cut information from a sensor on the frame; and wherein the controller is configured to change the length of the light displayed on the light bar depending on the depth of cut; and wherein the camera captures the first image of the light bar and sends the first image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

16. A method of providing a cutting rotor location to an operator of a milling machine, the method comprising:
coupling a camera to a frame of the milling machine, the camera positioned to capture a first image of an area proximate a cutting rotor of the machine, wherein the first image includes a view of a cutting surface adjacent a side of the frame and a portion of a side of the milling machine proximate the cutting rotor; and
displaying on a monitor in an operator station of the milling machine the first image from the camera and a visual image of a location of a leading edge and a trailing edge of the cutting rotor relative to the cutting surface.

17. The method of claim 16 , wherein the method further includes providing a controller configured to receive the first image from the camera, and to receive depth of cut information from a sensor on the frame, and to output a second image to the monitor to display on the monitor the visual image of the location of the leading edge and the trailing edge of the cutting rotor.

18. The method of claim 16 , wherein the method further includes a light coupled to the frame and configured to display a light indicative of the leading edge and trailing edge of the cutting rotor; and a controller to receive depth of cut information from a sensor on the frame; and wherein the controller is configured to change the size of the light depending on the depth of cut; and wherein the camer
