Ground engaging system for a machine

Abstract

A machine, such as a compactor, includes at least one ground-engaging member having a plurality of teeth. Often, debris or dirt builds up on the ground-engaging member between the teeth and must be removed for improved compaction. The teeth may have base and a tip with a width of the tip being greater than a width of the base. A scraper is provided having a second end configured adjacent a surface of the ground-engaging member. As the ground-engaging member rotates, the relatively stationary scrapers remove material, which would otherwise cause build-up beneath tips of the teeth.

1 . A machine, comprising: 
 a frame defined by a longitudinal axis;    a mounting bar connected to the frame transverse to the longitudinal axis;    a ground engaging member rotatably connected to the frame;    a plurality of teeth located at predetermined intervals in adjacent rows on a surface of the ground engaging member, each tooth having a base portion attached to the surface and a tip portion extending outwardly from the surface, the base portion being narrower than the tip portion; and    a plurality of scrapers, each scraper having a first end connected to the mounting bar and a second end located adjacent the surface, the second end having a width greater than a distance between adjacent tip portions and less than a distance between adjacent base portions.    
   
   
       2 . The machine of  claim 1 , each tooth further comprising: 
 the base portion having opposed first and second base sides and opposed first and second base ends; and    the tip portion having opposed first and second tip sides and opposed first and second tip ends;    wherein a distance between the first and second base ends is greater than a distance between the first and second tip ends and a distance between the first and second base sides is less than a distance between the first and second tip sides.    
   
   
       3 . The machine of  claim 2 , the teeth further including: 
 a first arcuate portion  60  connecting the first base side  46  to the first tip side  56 ; and    a second arcuate portion  63  connecting the second base side  48  to the second tip side  58 .    
   
   
       4 . The machine of  claim 2 , further including: 
 a first sloped portion  65  connecting the first base end  42  to the first tip end  52 ; and    a second sloped portion  67  connecting the second base end  44  to the second tip end  54 .    
   
   
       5 . The machine of  claim 2 , wherein the distance between base sides in adjacent rows defines a first space, and the distance between tip sides in adjacent rows defines a second space.  
   
   
       6 . The machine of  claim 5 , wherein the first space is greater in width than the second space.  
   
   
       7 . The machine of  claim 6 , wherein the second end of each scraper is further positioned in a portion of each respective first space.  
   
   
       8 . The machine of  claim 7 , wherein the first end of each scraper is connected to the second end of each scraper by a connecting portion, the connecting portion positioned in a corresponding second space.  
   
   
       9 . The machine of  claim 2 , each scraper second end further including opposed first and second sides.  
   
   
       10 . The machine of  claim 9 , wherein at least one of the scraper first and second sides are adjacent to at least one of the first and second base sides.  
   
   
       11 . The machine of  claim 9 , wherein at least one of the scraper first and second sides are adjacent to at least one of the first base sides of a plurality of teeth in a first row and the second base sides of a plurality of teeth in a second row.  
   
   
       12 . A tooth for a ground engaging member of a machine, comprising: 
 a base portion having opposed first and second base sides and opposed first and second base ends; and    a tip portion having opposed first and second tip sides and opposed first and second tip ends;    wherein: 
 a distance between the first and second base ends is greater than a distance between the first and second tip ends;  
 a distance between the first and second base sides is less than a distance between the first and second tip sides; and  
 the base portion is configured to attach to a surface of the ground engaging member, the tip portion extending outwardly from the surface.  
   
   
   
       13 . The tooth of  claim 12 , wherein the base portion is configured to be attached to the surface such that at least one of a first and second side of a scraper is located in a portion of a space adjacent at least one of the first and second base sides and beneath the corresponding first and second tip sides.  
   
   
       14 . A ground engaging system for a machine, comprising: 
 a ground engaging member rotatably connected to a frame of the machine;    a plurality of teeth located at predetermined intervals in rows on a surface of the ground engaging member, each tooth having a base portion attached to the surface and a tip portion extending outwardly from the surface, the base portion being narrower than the tip portion; and    a scraper having a first end configured to be connected to the frame and a second end configured to be located adjacent the surface, the second end having a width greater than a distance between adjacent tip portions and less than a distance between adjacent base portions.
