| 摘要 |
The invention provides apparatus for lifting a large parallelepiped bale of hay or straw from the ground and then loading the bale on a transport vehicle such as a flat bed trailer or truck. The apparatus includes a transport frame pivotally connected to one side of the vehicle for movement between a lower working position, an intermediate transition position and a vertical transport position. A lifting frame is pivotally connected to the distal end of the transport frame for pivotal movement about an axis that is angled relative to the transport frame. The axis is generally parallel to a line that extends diagonally of a bale from one lower inside corner to the opposite upper outside corner. A roller frame fixedly mounted to the lifting frame carries a pair of rollers, a stop member to properly locate a bale relative to the roller frame, and a pivotable clamp for clamping a bale against the roller frame. In operation the bale is clamped against the roller frame, the roller frame is pivoted upwardly and is simultaneously rotated inwardly by the lifting frame until the bale is normal to the vehicle and at the level of the support surface thereof. The rollers are operated to move the bale onto the support surface and then the entire apparatus is returned to its original position to accept another bale for loading onto the transport vehicle.
