Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
87 words
A mobile baler for hay or like crop material, comprising a baling chamber defining an inlet opening and a bale discharge gate opposite said inlet opening; pick up means including means for feeding the picked up crop material into said inlet opening under a feeding pressure; and openable holding means arranged in said baling chamber between said inlet opening and said discharge gate to stop the incoming crop material until it reaches a predetermined baling pressure and subsequently to pass the baled material towards said discharge gate.
Claim 2
Dependent Claim
87 words
A mobile baler for hay or like crop material, comprising a baling chamber defining an inlet opening and a bale discharge gate opposite said inlet opening; pick up means including means for feeding the picked up crop material into said inlet opening under a feeding pressure; and openable holding means arranged in said baling chamber between said inlet opening and said discharge gate to stop the incoming crop material until it reaches a predetermined baling pressure and subsequently to pass the baled material towards said discharge gate.
Claim 3
Dependent Claim
26 words
The baler as defined in claim 1 wherein said holding means includes at least one flap pivotably connected to the side walls of said baling chamber.
Claim 4
Dependent Claim
35 words
The baler as defined in claim 2 including a pair of flaps extending transversely to the feeding direction of the crop material and being hinged to the top and to the bottom of said chamber.
Claim 5
Dependent Claim
64 words
The baler as defined in claim 2 wherein said holding means includes an adjustable pressure generator coupled to said flap for holding the same in a closing angular position at which said flap extends across said baling chamber transversely to the feeding direction and to permit the tilting of the flap into an open position when said feeding pressure exceeds the predetermined baling pressure.
Claim 6
Dependent Claim
18 words
The baler as defined in claim 4, wherein said pressure generator is a hydraulic or pneumatic cylinder-and-piston unit.
Claim 7
Dependent Claim
28 words
The baler as defined in claim 5, wherein said pressure generator further includes a hydraulic pump connected to said hydraulic cylinder-and-piston unit via an adjustable pressure relief valve.
Claim 8
Dependent Claim
34 words
The baler as defined in claim 6, wherein said pick up means includes feed driving means operatively coupled to said pressure relief valve to release the baling pressure when the driving means are overloaded.
Claim 9
Dependent Claim
75 words
The baler as defined in claim 1 wherein said holding means includes a slidable frame arranged for movement in the feeding direction in said baling chamber, a transverse shield attached to said slidable frame, braking means for exerting a predetermined braking force against said slidable frame and a tiltable frame arranged at the discharge gate to engage and tilt the slidable frame when the latter is displaced by the incoming material from said baling chamber.
Claim 10
Dependent Claim
24 words
The baler as defined in claim 8, wherein said braking means includes a drum brake connected to said slidable frame by a pulling means.
Claim 11
Dependent Claim
36 words
The baler as defined in claim 1, wherein said feeding means includes a guiding channel communicating with said inlet opening and cooperating with feeding fingers for advancing the picked up crop material under said feeding pressure.
Claim 12
Dependent Claim
23 words
The baler as defined in claim 10, further including means for tieing the completed bale between said holding means and said discharge gate.
Claim 13
Dependent Claim
25 words
The baler as defined in claim 1, wherein said inlet opening and said discharge gate extends substantially over the entire width of said baling chamber.
