  • Publication number: 20230363315
    Abstract: A method for operating a round baler and a round baler are disclosed. The round baler has a baling chamber having a variable diameter and is bounded by a rotating pressing means. The pressing means is driven and/or guided by rollers, wherein some of the rollers are adjusted by a first and second clamping arms, each of which are pivotably mounted on the housing side. The first and second clamping arms are adjusted by actuators so that a compaction pressure is generated with which the pressing means acts to form a round bale. To regulate the compaction pressure, a pressure relief valve is given an adjustable limit pressure value to transition from a closed position into an open position. The limit pressure value lies above a pressure value which corresponds to a target pressing means tension to achieve the compaction pressure.

  • Publication number: 20230363318
    Abstract: A round baler and a method for operating a round baler are disclosed. The round baler has a variable diameter and is bounded by an endlessly rotating pressing means. The pressing means is guided by a plurality of rollers, wherein a loop of the pressing means is guided by a first clamping arm mounted on the housing side and by a second clamping arm mounted on the housing side. The first and second clamping arms are adjusted by actuators so that at least one compaction pressure is generated with which the pressing means acts to form a round bale. A control unit automatically controls the actuators depending on a compaction power curve, accounting for operating parameters and/or environmental parameters of the round baler, thereby maintaining a substantially stable operating point during the shaping process, in which the required compaction power and the available drive power are substantially equal.

  • Publication number: 20230084503
    Abstract: A square baler is disclosed. The square baler comprises: at least one ram arranged movably between end positions in a pressing channel, and a cutting rotor, and a drive train which is designed to drive at least the ram and the cutting rotor together, a torque input connection through which torque may be supplied to the drive train, and a first power split, such as a bevel gear stage, which is connected to the torque input connection. The drive train comprises at least one reduction gear associated with the ram. The reduction gear associated with the ram and the cutting rotor are connected in parallel to each other to the first power split. At least one side gear is connected between the first power split and the at least one reduction gear associated with the ram. And, at least one flywheel is connected between the at least one reduction gear associated with the ram and the at least one side gear.

  • Publication number: 20230077734
    Abstract: A gear assembly is disclosed for driving a ram arranged in a pressing channel of a square baler so as to be movable between end positions. The gear assembly comprises at least one side gear, which may be driven indirectly by a power take-off shaft of an agricultural production machine, and at least one reduction gear which is connected downstream from the at least one side gear and may be connected on the output side to a crankshaft on which the ram is mounted. The gear assembly further includes at least one flywheel that is connected between the at least one side gear and the at least one reduction gear, and at least one shiftable clutch device that is connected between the at least one flywheel and the at least one reduction gear.

  • Patent number: 8261512
    Abstract: A baler with a bale pressing chamber for agricultural stalk materials is connected with a wrapping device comprising a wrapping table for the enveloping of a bale with foil via at least one support frame carried by a chassis, between the baler and the wrapping device at least one actively driven bale transfer device for the transfer of the finished bale from the bale pressing chamber to the wrapping table of the wrapping device is present, and as a function of the inclination of the baler and/or the wrapping device to the perpendicular the operational sequence of the transfer of the bale from the bale pressing chamber to the wrapping device is controlled.
