Combine Harvester Rake Transfer Mechanism

The patent applies the dynamics principle by replacing static draw-in fingers with a movable packer mechanism that rotates on a crank arm. The packer's effective conveying length varies dynamically during rotation, being minimal at the transfer opening and maximum away from it. This dynamic configuration allows the packer to maintain structural simplicity while achieving sufficient conveying effect through its rotational motion and varying effective length.

The patent applies the dimensionality change principle by transforming the packer's movement path from a simple circular trajectory to an oval path through the introduction of a guide device with pendulum rods. This oval path extends the conveying area in the width direction of the cutterbar while maintaining mechanical simplicity. The guide device constrains the packer to follow this extended elliptical trajectory, effectively utilizing space in a new dimensional arrangement.

The patent applies the dynamics principle by making the packer tines rotate together with the packer mechanism rather than remaining fixed vertically. This dynamic orientation ensures that the tines maintain an optimal angle relative to the crop flow direction throughout the rotation cycle, preventing vertical acceleration that would cause blockages. The rotating tine configuration adapts continuously to the changing positions during the oval path movement.

The patent applies the dynamics principle by implementing a rotational packer mechanism where the effective conveying length varies continuously during rotation. At the transfer opening position, the effective length is minimal, maintaining compactness. As the packer rotates away from the transfer opening, the effective length increases, maximizing crop engagement. This dynamic variation allows the device to achieve both compactness and high transfer efficiency at different positions in its cycle.
