Abstract:
An agricultural press for forming round bales includes a plurality of rollers defining a pressing chamber, which are rotatably mounted partially on a load-bearing structure and partially on a structure that is articulated to the load-bearing structure and can be displaced into a raised position for unloading a round bale from the pressing chamber. The rollers are driven by electric motors, which, may be contained within the rollers or are of the type with hollow shaft, for receiving within them an end pin of the respective roller. The load-bearing structure and the structure articulated to the load-bearing structure are in the form of structures of the space-frame type with main lateral structures made of metal, preferably aluminium, obtained by casting.
Abstract:
A belt tracking control device for a conveyor device is provided, in particular for agricultural round balers, having at least one roller and at least one traction element which is guided over the roller and having at least one edge region which extends from the side edge of the traction element in the direction of the width thereof. At least one guide roller is provided through which the edge region can be deflected from the movement plane of the traction element.
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 utilised 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:
An improved roll belt guide mechanism for directing movement of a plurality of side-by-side belts in a round baler wherein adjacent belts are staggered to create opening through which trash mass pass to prevent trash accumulation behind the belts. A pair of offsetting rolls is positioned between two guide rolls defining the normal belt path. The offsetting rolls are aligned on axes that are parallel to the normal guide roll axes and arranged so that one offsetting roll is positioned generally forward of the other. One or more belts are directed around the forward offset roll while the remainder of the belts is directed around the rearward offsetting roll. The alignment and separation of the offsetting rolls is configured to allow roll belts of equal lengths to be used regardless of routing around the offsetting rolls. Trash removal may be improved by the addition of an auger in the space between the offset belts to urge the trash laterally, generally along the length of the offsetting rolls.
Abstract:
In one embodiment, a starter roll for a baler includes a continuous chevron-shaped rib provided on a contact surface of the starter roll. The rib may include a center portion arranged generally parallel to the longitudinal axis of the starter roll and outwardly and rearwardly extending wings. A plurality of ribs may be provided to form guide channels for guiding wrapping material that is provided to the bale and engaged by the starter roll outward to cover the edges of a bale and distribute the wrapping material over the lateral surface of the bale.
Abstract:
An improved roller assembly for use in machinery such as round balers is disclosed. The roller assembly of the present invention reduces sensitivity to varying dimensional tolerances on the roller assembly and the structure to which the roller assembly is mounted. At least one elastic member is used to permit the axial position of at least one of the bearings on the roller assembly shaft to vary. Spring washers provide a predetermined, axial force to at least one of the bearings.
Abstract:
A roller assembly for use with an agricultural baler is configured to be mounted to a housing of the baler in a manner that avoids transmitting an undue axial load to a bearing of the roller assembly. An associated method is disclosed.
Abstract:
A large round baler includes inner and outer runs of bale-forming belts that define a space between them in which brittle crop may fall through the gaps between adjacent belts and build up between the belt runs. In order to avoid wrapping problems a crop passage is provided at opposite sides of the space through which crop may pass from the space and gravitate to a crop feeding device which picks up crop from the ground and delivers it to the bale-forming chamber delimited by the inner run of belts.

Abstract:
A shaft is disposed along an axis of rotation and a bearing failure indicator, in the form of a disk having protrusions or teeth spaced about its periphery, is provided on the shaft adjacent a bearing supporting a tubular roll for rotation relative to the shaft. When the bearing has undergone a predetermined amount of wear, which happens prior to bearing failure, the teeth or protrusions of the disk come into engagement with a contact surface due to non-concentric rotation of the roll relative to the shaft. In one embodiment, the disk is thick and the teeth make an audible knocking sound which warns an operator of an impending bearing failure. In another embodiment, the disk is relatively thin and a squealing sound is generated when the protrusions engage the contact surface. In addition to the bearing failure indicator, a slip coupling may be used to prevent the transmission of torque to the drive shaft when interference between the disk and the contact surface occurs. Further, a secondary bearing may be provided to prolong operation of a wearing primary bearing.
