| 摘要 |
A wrapping mechanism is described that comprises at least two material support cylinders, a mechanism support cylinder, and a first and a second support plate, which are all rotatable about a support axis. The wrapping mechanism can comprise a pair of frame plates, a drive mechanism, a brake system, a lock mechanism, at least one feed roller and a feed plate. The wrapping mechanism can be integrated into an agricultural harvester such as a baler or combine. |

1. A wrapping mechanism comprising:
at least two material support cylinders, extending between a first and a second support plate and in operable contact with at least one of the first and second support plates, the at least two material support cylinders rotatably mounted around a support axis; a mechanism support cylinder operably connected to the first and second support plates and positioned on the support axis between the first and the second support plates around which the at least two material support cylinders revolve in a plurality of radial positions; and at least one drive mechanism operably connected to at least the first support plate such that the drive mechanism facilitates the revolution of the at least two material support cylinders from a first radial position to one of the plurality of radial positions around the support axis; a pair of oppositely facing frame plates; a lock mechanism; at least one feed roller; and a feed plate; wherein the at least two material support cylinders are operably attached to at least the first support plate; wherein the at least two material support cylinders are configured for supporting rolls of wrapping material, and optionally loading or unloading a roll of wrapping material at the first radial position around the support axis; and wherein at least one radial position of at least one material support cylinder is configured for dispensing wrapping material; anda brake system comprising:
at least one elongated member comprising a longitudinal axis, that defines a linear axis around which at least a first, a second, and a third non-coaxial elements are capable of movement; at least one coaxial element that is capable of rotation around the linear axis; a lever, operable in at least one engaged position and at least one or a plurality of disengaged positions, comprising at least a first and a second end, said first end proximate to and in operable contact with the elongated member, configured for rotational movement of the elongated member in the one or a plurality of disengaged positions; the first non-coaxial element extending transversely from the linear axis and attached to a least one counterwheel configured for exacting contact and pressure to a roll of wrapping material; the second non-coaxial element extending transversely from the linear axis comprising at least one end operably linked to the at least one coaxial element; the third non-coaxial element extending transversely from the linear axis positioned at or proximate to one end of and operably linked to the at least one coaxial element and operably connected to at least one brake pad; a spring, positioned between the first and second non-coaxial elements, operably linking at least one end of the first and second non-coaxial elements; and optionally, a hooked element comprising at least one curved member and at least one straight member, operably linked to and positioned at or proximate to one end of the at least one coaxial element. |
