Abstract

The thrower is attached to the discharge end of a baler in position to receive bales successively issuing therefrom. A pair of generally superimposed conveyors of the thrower operate at relatively high speeds compared to the speed at which the bales issue from the baler, and as the leading end of each bale enters the awaiting thrower, the high speed conveyors grab the bale and propel it upwardly and rearwardly toward an awaiting receptacle such as a trailing wagon. The upper conveyor is so mounted that it clamps down in a self-actuating manner against the bale as the latter enters the thrower and makes engagement with the propelling surfaces of the conveyors, such clamping action arising from the reaction force generated by the slowly moving bale contacting the rapidly moving surface of the upper conveyor.

Claims8

Dependent claims

A bale thrower adapted for attachment to the discharge end of a baler for receiving bales successively issuing therefrom and for throwing the same in succession into a remote receptacle or the like, said thrower comprising:

a pair of opposed conveyors located on opposite sides of the normal path of travel of bales through the thrower and defining a bale entrance and a bale exit of the thrower,
said conveyors being provided with respective bale-engaging surfaces driven in directions corresponding to the direction of bale travel from said entrance to said exit;
and
means mounting said conveyors for relative shifting thereof toward one another in an area that includes said entrance in response to entry of a bale into the entrance and engagement of the bale with said surfaces whereby to clamp the conveyors about the entering bale as said surfaces cooperate to propel the bale along said path of travel.
