Abstract:
A machine to form compact rolls of hay of substantial size by picking up a swath or windrow of hay and the like from a field, engage it by cooperating upper and lower endless flexible aprons driven in suitable directions to coil the hay into a compact roll while supported upon floor means mounted stationarily in the bottom of the machine to effect baling of all the hay without loss upon the ground. When the roll type bale of hay reaches a predetermined diameter, the upper apron raises to stop driving the same and provide an exit and the lower apron assists in ejecting the bale onto the ground, or the machine can transport it to a desired location for discharge. The lower apron in particular has aggressive type lugs to insure positive engagement with the roll to rotate it relative to the floor means, and the discharge end of the floor means is arranged to positively withdraw the lugs from the roll except when discharge is to occur. When discharge is to occur the discharge end of the floor means is depressed to permit the lugs to continue to engage the roll to remove it from the machine.
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.
Abstract:
A round baler is provided with a bale-forming chamber that is surrounded by a pressing apparatus in the form of a single pressing belt or several pressing belts arranged one next to the other, wherein the pressing apparatus contacts a roller that can be driven and freely co-rotating rollers, of which at least one pre-tensioned roller is loaded by pre-tensioning apparatus in the sense of tightening the pressing apparatus such that it pre-tensions the pre-tensioned roller more strongly the farther this roller moves in a direction for loosening the pressing apparatus. The two ends of the pre-tensioned roller are each pre-tensioned by the pre-tensioning apparatus and can move independently of each other.
Abstract:
An improved belt guide system has individual guide sleeves mounted on one or more of the guide rolls, one sleeve for each belt, in an agricultural round baler. Each sleeve encircles the roll surface of the guide roll and is positioned between the belt and the guide roll surface in a manner allowing relative rotational movement between the sleeve and the guide roll. Each guide sleeve is thus allowed to match the peripheral speed of the respective belt as it passes over the guide roll and allow slippage to occur between the guide roll surface and the inner circumference of the guide sleeve. Flanges extending radially outwardly on each sleeve end maintain the sleeve alignment with the respective belt.

Abstract:
A bearing support assembly (10) comprising a bearing (12) supported within a bearing block (14) is provided. A shaft (26) is arranged to rotate within the bearing (12) and a disc member (34) is carried on the shaft (26) proximate to the bearing block (14). A ring member (20) is secured to the bearing block (14) so that in the event of bearing failure the disc member (34) engages with the ring member (20) so as to support the shaft (26) in rotational motion. The disc member has a diameter that is larger than the outer diameter of the ring member. The ring member (20) is at least partially recessed into the thickness of the disc member (34). The assembly may be utilized in agricultural machinery which include rotors (30) which are supported on rotating shafts. The ring member (20) may provide a labyrinth seal which inhibits the ingress of particulate matter into the bearing.
Abstract:
A round baler is described having a housing with two sidewalls and a plurality of belts arranged side by side within the housing between the sidewalls and guided over rolls of which at least some are mounted movably to permit a baling to increase in diameter as the bale being formed grows in size. The movable rolls are supported by a belt tension arm assembly having radius arms extending from an axle that is rotatable relative to the housing about an axis parallel to that of the rolls. The rolls nearest the sidewalls of the housing are cantilevered mounted on the belt tension arm assembly to extend laterally beyond the radius arms.
Abstract:
A drive roller for flat belts is provided in various embodiments wherein the roller has improved characteristics for maintaining traction of belts, such as lagging applied to the roller.
