Work machine and display system

Abstract

A work machine comprises a body, a ripper apparatus that is disposed behind the body, and an imaging device that is mounted to the body and images the ripper apparatus. The ripper apparatus includes a shank, a ripping tip that is attached to an end of the shank, a beam that supports the shank, and a ripper arm that interconnects the body and the beam. The imaging device images the ripper apparatus sideways and captures an image in a range including at least a portion of the shank, at least a portion of the beam, and at least a portion of the ripper arm.

What is claimed is: 
     
         1 . A work machine comprising:
 a body;   a ripper apparatus that is disposed rearward of the body; and   an imaging device that is mounted to the body and captures an image of the ripper apparatus, wherein   the ripper apparatus includes a shank, a ripping tip that is attached to an end of the shank, a beam that supports the shank, and a ripper arm that interconnects the body and the beam, and   the imaging device images the ripper apparatus sideways and captures an image in a range including at least a portion of the shank, at least a portion of the beam, and at least a portion of the ripper arm.   
     
     
         2 . The work machine according to  claim 1 , wherein
 the ripper apparatus further includes a tilt cylinder that causes the ripping tip to reciprocate in a direction toward the body and a direction away from the body, and   the imaging device captures an image in a range including at least a portion of the tilt cylinder.   
     
     
         3 . The work machine according to  claim 1 , wherein
 the ripper apparatus further includes a lift cylinder that causes the ripping tip to move up and down, and   the imaging device captures an image in a range including at least a portion of the lift cylinder.   
     
     
         4 . The work machine according to  claim 1 , wherein the imaging device images the ripper apparatus on a left side. 
     
     
         5 . The work machine according to  claim 1 , further comprising:
 a ripping tip imaging device that is mounted to the body and captures an image in a range including the ripping tip; and   a rear imaging device that is mounted to the body and captures an image in a range including a range of a rear side of and rearward of the body.   
     
     
         6 . A display system comprising:
 the work machine according to  claim 5 ; and   a display device that simultaneously displays an image captured by the ripping tip imaging device, an image captured by the rear imaging device, and an image captured by the imaging device.   
     
     
         7 . The display system according to  claim 6 , wherein the display device is caused to display the image captured by the ripping tip imaging device, the image captured by the rear imaging device, and the image captured by the imaging device such that the images are aligned from left to right. 
     
     
         8 . The display system according to  claim 6 , wherein the display device is disposed outside the work machine.
