Abstract

A round baler includes a bale-forming chamber with a belt assembly for rolling a bale, the assembly includes a plurality of parallel side-by-side belts trained about rollers transverse to the belts, wherein the rollers have a shaft with a plurality of belt-driving sleeves mounted thereon. The belt-driving sleeves have a circumferential groove and the belts have a longitudinal protrusion to track the belt in the groove of the belt-driving sleeve.

First claim

The invention claimed is:

1. A round baler comprising:
a bale-forming chamber is at least partially formed by a belt assembly for rolling a bale therein,
the belt assembly comprising a plurality of belts trained about rollers transverse to the belts,
wherein each of the rollers comprises a shaft with a plurality of belt-driving sleeves mounted thereon, and the plurality of belt-driving sleeves each having a circumferential groove, the circumferential groove is wedge shaped, and the belts each having a longitudinal protrusion configured to track the belt in the groove of the belt-driving sleeve, wherein the longitudinal protrusions of the belts have toothed longitudinal cross-sections comprising teeth positioned immediately adjacent to each other, wherein the teeth are configured as a scraper to remove debris from the groove, and wherein the belt-driving sleeves are mounted on the shaft immediately adjacent to each other.

2. The round baler according to claim 1 , wherein the shaft has a flat surface and the belt-driving sleeves have a height greater than a depth of the groove.

3. The round baler according to claim 2 , wherein the depth of the groove is from 30% to 70% of the height of the belt-driving sleeve.

4. The round baler according to claim 1 , wherein the belt-driving sleeves have a plurality of interconnected channels at an internal surface of the belt-driving sleeve, the channels being connected with an opening in an outer surface of the belt-driving sleeve, via which an adhesive is introduced between the internal surface of the belt-driving sleeve and the outer surface of the shaft.

5. The round baler according to claim 1 , wherein the belt-driving sleeves have a width larger than the width of the belt providing a clearance between the belts such that debris can be removed.

6. The round baler according to claim 1 , wherein the belt-driving sleeves have a convex outer surface in which the grooves are formed.

7. The round baler according to claim 1 , wherein the belt-driving sleeves are molded from rubber or hard plastic.

8. A round baler comprising a bale-forming chamber with a belt assembly for rolling a bale, the belt assembly comprising:
a plurality of parallel side-by-side belts trained about rollers transverse to the belts,
wherein each of the rollers comprises a shaft with a plurality of belt-driving sleeves mounted thereon,
wherein the belt-driving sleeves each have a convex outer surface and a plurality of circumferential grooves and each of the belts have a plurality of longitudinal protrusions configured to track the belt in the grooves of the belt-driving sleeve and act as a scraper to remove debris from the groove, wherein a first circumferential groove of the plurality of circumferential grooves is located at a central section of the sleeves having a different diameter than a second circumferential groove of the plurality of circumferential grooves located at a side section, and wherein the belt-driving sleeves are mounted on the shaft immediately adjacent to each other.
