Abstract
An improved bale thrower for use with a hay baler is disclosed. The thrower affixes to the discharge end of the bale case of the baler and can be selectively pivoted vertically about at least one horizontal axis between a first operative position for directionally ejecting bales and a second inoperative position which allows the bales to be deposited directly on the ground behind the baler.
Claims10
A bale thrower adapted to be affixed to the discharge end of the bale case of a hay baler, said bale case having a top wall and a bottom wall, said bale thrower comprising:
- (a) a first frame means adapted to be fixed to the discharge end of the bale case;
- (b) a second frame means pivotally fixed about a vertical axis to said first frame means;
- (c) bale ejector means pivotally fixed about at least one horizontal axis to said second frame means, said bale ejector means including first and second friction means for movably engaging, respectively, opposing sides of a bale, whereby said bale ejector means may be pivoted vertically about said at least one horizontal axis between operational and non-operational positions relative to the bale case;
- and
- (d) drive means operably connected to said bale ejector means.
The combination of a hay baler and a bale thrower, said combination comprising:
- (a) a hay baler having an elongated bale case which extends in a fore-and-aft direction relative to ground travel, said bale case having a top wall and a bottom wall and including a rearward end opening through which bales are discharged;
- (b) a first frame means affixed to the discharge end of the bale case;
- (c) a second frame means pivotally fixed about a vertical axis to said first frame means;
- (d) a bale thrower pivotally affixed to said second frame means for selective movement about at least one horizontal axis between a first position in operative alignment with said rearward end opening of said bale case and a second position wherein said entire bale thrower is substantially out of alignment with said rearward end opening of said bale case;
- and
- (e) drive means operably connected to said bale thrower.
A bale thrower for baling machines including a bale-forming chamber, said bale thrower comprising:
- (a) a frame means adapted to be pivotally mounted adjacent the bale discharge end of the bale-forming chamber for lateral movement about a vertical axis, said frame means including a lower bale support, said bale support having a horizontal portion in substantial alignment with the bottom of the bale-forming chamber, and an adjustable portion pivotably connected to said horizontal portion for movement about a horizontal axis to selectively guide bales upwardly or downwardly;
- (b) conveyor means pivotally mounted on said frame means for vertical movement about at least one horizontal axis from a first operative position to a second inoperative position which does not obstruct the discharge of bales from the bale-forming chamber, said first position being at a positive angle with the horizontal to eject the bales in a generally upward direction, said conveyor means including first and second endless belt conveyors vertically spaced from each other a distance substantially equal to the height of the bales discharged from the bale-forming chamber into said conveyor means;
- (c) guide means connected to said frame means for laterally directing bales from the bale-forming chamber to said conveyor means;
- and
- (d) drive means operably connected to said frame means for driving said endless belt conveyors in opposite directions to engage and eject bales.
