摘要:
A net wrap system is disclosed. The net wrap system moves wrap material for agricultural crop packages within a baler (10) with a wrap roller (30), the net wrap system comprising: a motor (24) secured to the baler (10), the motor (24) being configured to rotate the wrap roller (30); and a controller (28) configured to: cause the motor (24) to rotate the wrap roller (30) in a first direction (46), such that the wrap roller (30) moves the wrap material towards a crop package contained by the baler (10); and during application of the wrap material to the crop package, cause the motor (24) to one or more of brake the wrap roller (30) relative to the first roller direction and rotate the wrap roller (30) in a second direction (48) that is opposite the first direction (46), in order to stretch the wrap material. Furthermore, a respective method of operation is disclosed.
摘要:
A baler (10) is disclosed. The baler (10) comprises: a frame (20); a bale-wrapping system including a surface-wrap guide roller (32); a counterknife assembly including a support member (74) rotatably mounted to the frame (20) and a counterknife arm (72, 94) mounted to the support member (74), the counterknife arm (72, 94) pivoting to cause a counterknife (34) to cut surface wrap when the support member (74) rotates with respect to the frame (20); a pulley member (40) attached to and rotating with the guide roller (32); a traction device (54) surrounding, at least in part, the pulley member (40); a tensioning assembly (30) attached to the frame (20) at a frame attachment point (90) of the tensioning assembly (30), the tensioning assembly (30) including a lost motion linkage limited by a stop to a limited range of motion with respect to the frame (20), the lost motion linkage being attached to a first end of the traction device at a brake attachment point (88) of the tensioning assembly (30), and attached to the support member (74) at the frame attachement point (90) of the tensioning assembly (30); and a counterforce assembly (28) attached to a second end of the traction device (54) at a brake attachment point (56) of the counterforce assembly (28), and pivotably attached to the frame (20) at a frame attachment point (58) of the counterforce assembly (28); wherein rotating the support member (74) in a braking direction with respect to the frame (20) causes the tensioning assembly (30) to pivot in the braking direction to move the lost motion linkage toward the stop such that the stop prevents further movement of the lost motion linkage with respect to the frame (20), the tensioning assembly (30) thereby applying a first tensioning force to the traction device (54), the first tensioning force being resisted by the first counterforce assembly (28), via the brake attachment point (56) of the counterforce assembly (28), to impose a braking force on the pulley member (40) via the traction device (54) and thereby brake the guide roller (32).
摘要:
A brake system (400) is described that comprises at least one elongated member (410) and a lever (430), operable in an engaged position and at least one or a plurality of disengaged positions. The brake system further comprises a first non-coaxial element (440) is configured for exacting contact and pressure to a roll of wrapping material, a second non-coaxial element (450) being operably linked to the first non-coaxial element (440), and a third non-coaxial element (460) operably linked to the at least one coaxial element (420) and operably connected to at least one brake pad (461). The lever plate system can be integrated into an agricultural harvester such as a baler or combine.
摘要:
A web wrap apparatus (18) is provided in a round baler (10) and has a feeder (40), a separator (42) for the web (32) and a motion means (36). An actuator (56) is provided at the motion means (36), which assists the separator (42) in cutting the web (32), when the separator (42) gets close to the cutting position.
摘要:
Provided is a film letting-off device for a rolled bale V, which is arranged immediately upstream of a roll baling device B for covering and wrapping the outer circumference of the rolled bale V with a film F, for letting off said film F. A width reducing device H, which is constituted such that a pair of width reducing rollers 96 arranged in the widthwise direction of the film F so as to reduce the width of the film F being let off from a film rolling device E, while said rolled bale V is being covered with the film F, are brought close to and apart from each other while being centered, is arranged between said film rolling device E and said drive roller device D.
