Abstract

Abstract Semicontinuous formation of round bales is permitted by positively capturing material introduced into the bale-forming chamber of a round baler after ejection of the last-formed bale and while the web normally defining the chamber remains displaced from its forming position. In one embodiment, the crop-capturing function is performed by a grid comprising a plurality of parallel, upwardly arcuate, elongate bars forwardly mounted on the baler for swinging movement about a transverse axis toward and away from the lower apron of the chamber. Another embodiment employs a rearwardly mounted, vertically swingable grid of parallel, substantially rectilinear, elongate bars to positively retain crop material in the chamber.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 132 words
In a machine for forming round bales of crop material: means presenting movable, upwardly facing surface; a pickup adapted for directing crop material to said surface; a flexible web supported over said surface and cooperating therewith to define an enclosed, substantially cylindrical, radially expansible bale-forming chamber for rolling said crop material into a diametrically increasing round bale, said web having a shiftable portion for opening said chamber to permit ejection of said bale from the chamber when the bale is fully formed; and structure cooperable with said surface and said web to reestablish the closure of said chamber after said bale is ejected and while said portion remains in the open position such that crop material subsequently delivered to said surface is retained in said chamber for inclusion in the next bale.
Claim 2
Dependent Claim 132 words
In a machine for forming round bales of crop material: means presenting movable, upwardly facing surface; a pickup adapted for directing crop material to said surface; a flexible web supported over said surface and cooperating therewith to define an enclosed, substantially cylindrical, radially expansible bale-forming chamber for rolling said crop material into a diametrically increasing round bale, said web having a shiftable portion for opening said chamber to permit ejection of said bale from the chamber when the bale is fully formed; and structure cooperable with said surface and said web to reestablish the closure of said chamber after said bale is ejected and while said portion remains in the open position such that crop material subsequently delivered to said surface is retained in said chamber for inclusion in the next bale.
Claim 3
Dependent Claim 32 words
In a machine as claimed in claim 1, wherein said structure includes a grid pivotally mounted at one end for vertical swinging movement of the grid toward and away from said surface.
Claim 4
Dependent Claim 17 words
In a machine as claimed in claim 2, wherein said grid is yieldably biased toward said surface.
Claim 5
Dependent Claim 35 words
In a machine as claimed in claim 3, wherein said one end is positioned forwardly above said surface such that said grid moves away from the surface when the grid is swung upwardly and forwardly.
Claim 6
Dependent Claim 14 words
In a machine as claimed in claim 3, wherein said grid is upwardly arcuate.
Claim 7
Dependent Claim 35 words
In a machine as claimed in claim 3, wherein said one end is positioned rearwardly of said surface such that said grid moves away from said surface when the grid is swung upwardly and rearwardly.
Claim 8
Dependent Claim 25 words
In a machine as claimed in claim 6, wherein said structure includes a stop for limiting the swinging movement of said grid toward said surface.
Claim 9
Dependent Claim 14 words
In a machine as claimed in claim 3, wherein said grid is substantially planar.
Claim 10
Dependent Claim 20 words
In a machine as claimed in claim 1, wherein said flexible web comprises a plurality of laterally spaced, endless belts.
Claim 11
Dependent Claim 52 words
In a machine as claimed in claim 9, wherein said structure includes a grid mounted for vertical swinging movement toward and away from said surface, said grid comprising a plurality of parallel, laterally spaced, elongate bars aligned with the spaces between said belts whereby and grid may be swung through said web.
Claim 12
Dependent Claim 36 words
In a machine as claimed in claim 1, wherein said machine includes a support for said web, said support having a pair of laterally spaced, upstanding sidewalls, said structure substantially spanning the distance between said sidewalls.
Claim 13
Dependent Claim 29 words
In a machine as claimed in claim 11, wherein said structure includes a grid pivotally mounted on said sidewalls for vertical swinging movement about an axis extending transversely therebetween.
