A device for stubble treatment once a crop has been harvested having a frame, at least one knife rolling segment connectable to the frame through a pair of bearings to operate substantially horizontally, a vibration-absorbing arrangement for each bearing that is adapted to be mounted between a bearing and a free-end of the frame that has vibration-absorbing elements that are at least partially made of a resilient material to isolate the frame from vibrations generated at the rolling segment, a first plate to be attached to the free-end of the frame and a second plate adapted to be attached to the bearing, the plates being adapted to be fastened together. Two or more vibration-absorbing elements are positioned in-between the plates, wherein two vibration-absorbing elements are positioned symmetrically with respect to the center of the plates. |

1. A device for stubble treatment once a crop has been harvested, comprising:
a frame, a pair of bearings, at least one knife rolling segment adapted to be coupled to said frame by said bearings so as to operate substantially horizontally, and a vibration-absorbing arrangement for each bearing which is adapted to be mounted between a bearing and an end of said frame, wherein said vibration-absorbing arrangement has at least two vibration-absorbing elements and is at least partially made of a resilient material adapted to isolate the frame from vibrations generated at the at least one rolling segment and propagated to each bearing, wherein said vibration-absorbing arrangement further comprises a first plate and a second plate, said first plate being adapted to be attached to the free-end of said frame and said second plate being adapted to be attached to a respective said bearing, said plates being adapted to be fastened together, wherein two said at least two vibration-absorbing elements are positioned in-between said plates symmetrically with respect to the center of the plates, and wherein said second plate has a through hole for each vibration-absorbing element, wherein each vibration-absorbing element has a first portion positioned in-between said plates, a second portion accommodated in said through hole and a third portion fastened underneath said second plate, and wherein said vibration-absorbing arrangement further comprises a third plate for each vibration-absorbing element, each third plate being positioned in-between the first plate and the second plate and having a through hole in which the second portion of each vibration-absorbing element is accommodated, said third plate being adapted to be fastened to said second plate. |
