Bale stacker

A bale stacker for consolidating a plurality of bales into a bale stack, comprising:

• a bale stacker chassis having a chassis front end and a chassis rear end supported for translational motion over a surface;
• a pair of elongate lift arms pivotally coupled in spaced apart relation to said chassis front end by lift arm first ends and outwardly extending from said chassis front end to terminate in lift arm second ends, said elongate lift arms rotatable from a primarily horizontal orientation to a primarily vertical orientation in relation to said bale stacker chassis;
• a bale gripper crosspiece rotatably coupled to said lift arm second ends;
• a pair of bale gripper arms each including one elongate bar, said bale gripper arms having bale gripper arm first ends correspondingly pivotally coupled to opposite bale gripper crosspiece ends and outwardly extending from said bale gripper crosspiece ends to terminate in bale gripper arm second ends;
• a bale receiving platform disposed over said bale stacker chassis, said bale receiving platform located to receive a bale from said bale gripper arms, said bail receiving platform rotatable from a generally horizontal orientation in relation to said bale stacker chassis toward an angled relation with said bale stacker chassis;
• a bale transfer table having a bale transfer table first end pivotally coupled to said bale stacker chassis and extending in an angled relation to said bale stacker chassis to dispose a bale transfer table second end in a first orientation relative to said bale receiving platform;
• a bale stack bed including a bale stack bed first end opposite a bale stack bed second end, said bale stack bed pivotally mounted to said bale stacker chassis to allow rotation of said bale stack bed between an angle of about twenty degrees relative to said bale stacker chassis and an angle of about ninety degrees relative to said bale stacker chassis;
• at least one fork disposed in generally orthogonal relation to said bale stack bed, said fork movable between said bale stack bed first end and said bale stack bed second end;
• wherein
• said bale gripper arms rotatable to decrease distance between said bale gripper arm second ends to secure said bale between said bale gripper arms;
• said bale gripper crosspiece rotatable to orient said bale gripper arms over said bale receiving platform;
• said bale gripper arms rotatable to increase distance between said bale gripper arm second ends to release said bale from said bale gripper arms to said bale receiving platform;
• said bale transfer table second end is rotatable to place said bale transfer table in a generally vertical orientation in relation to said bale stacker chassis and wherein when said bale transfer table resides in said generally vertical orientation and said fork is moved toward said bale stack bed second end, said generally vertical orientation places said bale stack on said bale stack bed abutting said fork.

• said bale receiving platform overlaps said bale transfer table second end when said bale transfer table second end resides in said first orientation relative to said bale receiving platform;
• said bale transfer table first end proximate said bail stack bed second end, said bale transfer table second end distal said bale stack bed second end.

A bale stacker for consolidating a plurality of bales into a bale stack, comprising:

• a bale stacker chassis;
• a bale receiving platform disposed over said bale stacker chassis;
• a pair of bale gripper arms coupled to a bale stacker chassis front end in spaced apart relation, said bale gripper arms rotatable about a first pivot axis to dispose a bale lifted from a surface on said bale receiving platform;
• a bale transfer table downstream of said bale receiving platform;
• said bale receiving platform rotatable about a second pivot axis for disposition in angled relation to said bale stacker chassis and above said bale transfer table in spaced apart relation to allow said bale to slide via gravity from said bale receiving platform to said bale transfer table;
• a bale stack bed downstream of said bale transfer table;
• said bale transfer table rotatable about a third pivot axis to generate a bale stack of two or more said bales proximate a bale stack bed second end;
• said bale stack bed rotatable about a fourth pivot axis for disposition in angled relation to said bale stacker chassis to dispose said bale stack on said surface.
