Abstract
A device for baling crop comprising a baling chamber having an inlet port and a ram adapted to reciprocate along said port and an auxiliary space joining the inlet port outside the baling chamber for temporalily storing crop to be compressed, said device is provided with a blocking member for predensifying the crop as well as compressing means for compressing the crop in a transverse direction in said auxiliary space, the blocking member is driven by means of a cam/cam wheel mechanism actuated by said ram, while said device furthermore comprises retaining members in said baling chamber to prevent rebounding of crop material already compressed and/or to retain crop in said baling chamber if said chamber is opened during the discharge of a bale.
Claims17
A baling machine comprising, in combination:
- an elongate frame defining a baling chamber and including wheel means for allowing the frame to be moved over a field;
- a ram reciprocable within said baling chamber, said baling chamber having an end wall cooperable with said ram for compressing crop therebetween to form a bale, and said chamber also having an inlet port spaced from said end wall;
- drive means for moving said ram from an extended position disposed between said inlet port and said end wall, to a retracted position disposed on the opposite side of said inlet port and then returning said ram to said extended position;
- a collection chamber carried by said frame and having an inlet mouth for receiving the crop material to be baled and having a discharge port joined with said inlet port of the baling chamber;
- means for introducing windrowed crop material into said inlet mouth whereby the crop material accumulates within said collection chamber;
- flap means blocking said inlet port for normally preventing movement of accumulated crop material from said collection chamber into said baling chamber, said flap means comprising a plurality of tines and mechanism for mounting said tines on said frame for 360.degree. rotation in which said tines sweep upwardly into the baling chamber and thereafter downwardly to pass out of the baling chamber, into said collection chamber and back to their original positions blocking said inlet port, said collection chamber being slotted to permit downward sweeping of said tines thereinto and said tines being of a length sufficient to pick up enough crop material from the collection space as to form a compressed mass of the same within said baling chamber;
- and
- coupling means connecting said drive means to said flap means so that said flap means is swept through its 360.degree. rotation as said ram is moved from its extended to its retracted positions and remains thereafter in its blocking position as the ram is returned to its extended position.
5 more elements
A device for baling a crop such as grass or the like, comprising in combination:
- a mobile frame defining a generally horizontal baling chamber having an end wall against which the crop is to be compressed and having a laterally facing inlet opening spaced from said end wall;
- a ram reciprocable within said baling chamber toward and away from said end wall and drive means for reciprocating said ram between a retracted position clearing said inlet opening and an extended position adjacent said end wall;
- an auxiliary chamber communicating with said baling chamber through said inlet opening and feeding means for continuously feeding crop into said auxiliary chamber;
- and
- transfer means for periodically transferring accumulated material from said auxiliary chamber to said baling chamber, said transfer means comprising at least one member rotatable about an axis transverse to the length direction of said baling chamber, said drive means being connected with said transfer means for movement of said member in synchronism with movement of said ram whereby said member sweeps material from said auxiliary chamber into said baling chamber as said ram moves toward said retracted position and thereafter temporarily resides in inlet opening-blocking position while said ram moves toward said extended position.
2 more elements
In a baling device, the combination of:
- a generally horizontal baling chamber having an end wall against which material is to be compressed and having a bottom inlet opening spaced from said end wall;
- an auxiliary chamber below said inlet opening and communicating with said baling chamber through said inlet opening and feed means for delivering material into said auxiliary chamber;
- transfer means for periodically sweeping material accumulated in said auxiliary chamber upwardly into said baling chamber and temporarily confining it in the latter;
- a ram reciprocable within said baling chamber toward and away from said end wall from one side of said inlet opening to the other;
- and
- drive means for synchronously moving said ram and said transfer means whereby said transfer means temporarily confines the material in said baling chamber as said ram is advancing across said inlet opening toward said end wall;
- said transfer means comprising at least one member rotatable through 360.degree. about an axis transverse to the length direction of said baling chamber.
4 more elements
In a baling device, the combination of:
- a generally horizontal baling chamber having an end wall against which material is to be compressed and having an inlet opening spaced from said end wall;
- a ram reciprocable within said baling chamber between a retracted position clearing said inlet opening on that side thereof remote from said end wall and an extended position clearing said inlet opening but disposed between the inlet opening and the end wall;
- an auxiliary chamber communicating with said baling chamber through said inlet opening;
- feeding means for feeding material into said auxiliary chamber;
- transfer means for periodically sweeping accumulated material from said auxiliary chamber to said baling chamber, said transfer means including at least one member normally lying substantially in the plane of said inlet opening and rotatable about an axis transverse to the length direction of said baling chamber to sweep successively through said baling chamber and said auxiliary chamber as the member is rotated 360.degree. from and to its normal position;
- and
- drive means for synchronously actuating said ram and said member such that said member remains in its normal position as the ram is moved from its retracted to its extended position and rotates through 360.degree. as said ram is moved from its extended to its retracted position.

In a baling device, the combination of:
- a generally horizontal baling chamber having an end wall against which material is to be compressed and having a downwardly facing inlet opening spaced from said end wall;
- a ram reciprocable within said baling chamber between a retracted position clearing said inlet opening on that side thereof remote from said end wall and an extended position clearing said inlet opening but disposed between the inlet opening and the end wall;
- an auxiliary chamber below said baling chamber and communicating therewith through said inlet opening;
- feeding means for feeding material into said auxiliary chamber;
- transfer means for periodically sweeping accumulated material from said auxiliary chamber to said baling chamber, said transfer means including at least one member normally lying generally in the plane of said inlet opening and rotatable about an axis transverse to the length direction of said baling chamber to sweep successively through said baling chamber and said auxiliary chamber as the member is rotated 360.degree. from and to its normal position;
- and
- drive means for synchronously actuating said ram and said member such that said member remains in its normal position as the ram is moved from its retracted to its extended position and rotates through 360.degree. as said ram is moved from its extended to its retracted position;
- said auxiliary chamber including a generally horizontal bottom wall and an arcuate wall leading from said bottom wall to that side of the inlet opening closest to said end wall, said arcuate wall being substantially concentric with the axis of rotation of said member whereby a large volume of space in said auxiliary chamber is swept by said member.
