Abstract
Abstract The apparatus aspects of the invention consists of packing means mounted at the discharge end of a harvesting wagon particularly one having a movable bottom. Such packing means may consist of such pressure creating means as multiple screws, oscillating vanes or rotary paddles for discharging the crop materials against the mass of animal food being built and imposing pressure thereon. Suitably adjustable braking means are also provided for controlling the pressure required to be imposed against the food mass in order to move the pressure creating means by the reaction thereto.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
122 words
A device for building up and removing a stored mass of material, in particular crop material, comprising: guide means; crop conveying and pressing means movably supported on said guide means; feeding means for feeding said crop material to said crop conveying and pressing means; control means for controlling the speed of movement of said crop conveying and pressing means along said guide means in response to the amount of material fed by said feeding means; and storage means including flexible cover means for receiving said mass of material and for storing said mass of material in an air-tight manner, said crop conveying and pressing means conveying said crop material to said storage means and pressing said crop material in said storage means.
Claim 2
Independent Claim
122 words
A device for building up and removing a stored mass of material, in particular crop material, comprising: guide means; crop conveying and pressing means movably supported on said guide means; feeding means for feeding said crop material to said crop conveying and pressing means; control means for controlling the speed of movement of said crop conveying and pressing means along said guide means in response to the amount of material fed by said feeding means; and storage means including flexible cover means for receiving said mass of material and for storing said mass of material in an air-tight manner, said crop conveying and pressing means conveying said crop material to said storage means and pressing said crop material in said storage means.
Claim 3
Dependent Claim
56 words
A device according to claim 1, wherein said crop conveying and pressing means includes a forming channel for forming said mass arranged on guide means and wherein said forming channel includes pressing members for pressing said crop material into said storage place, and a support plate at the end of the mass defining a boundary wall.
Claim 4
Dependent Claim
22 words
A device according to claim 2, wherein the guide means supporting the forming channel and the pressing members runs on guide rails.
Claim 5
Dependent Claim
37 words
A device according to claim 3, wherein the speed of forward movement of the forming channel along said guide rails is regulatable corresponding to the desired pressing of the mass with the help of an adjustable brake.
Claim 6
Dependent Claim
19 words
A device according to claim 4, wherein the speed of forward movement of the forming channel is automatically controllable.
Claim 7
Dependent Claim
37 words
A device according to claim 2, wherein said flexible cover means includes a rolled or folded coveR foil adapted to be pulled off from the forming channel during the forming process to cover the mass from above.
Claim 8
Dependent Claim
15 words
A device according to claim 2, wherein a ventilation means is provided under the mass.
Claim 9
Dependent Claim
19 words
A device according to claim 6, wherein the foil closes off the mass airtight or covers same from above.
Claim 10
Dependent Claim
53 words
A device according to claim 1, wherein the conveying and pressing device consists of an upwardly open fill-in part, a pressing channel following thereafter and a mouthpiece connected to said pressing channel, and that in the pressing device one or several inclined upwardly directed worms which partly project into the mouthpiece are arranged.
Claim 11
Dependent Claim
43 words
A device according to claim 9, wherein the worms have an inclination decreasing from the feed zone to the mouthpiece, whereby at least one part of the last worm path is bent back, and that the worm end ends in a conical tip.
Claim 12
Dependent Claim
42 words
A device according to claim 9, wherein the worms are arranged in oppositely directed pairs and the wall enclosing the respective worm is interrupted between two adjacent worms rotating in feeding direction by an opening which is enlarged toward the worm end.
Claim 13
Dependent Claim
19 words
A device according to claim 9, wherein the worms preferably discharge into the upper half of the mouthpiece cross-section.
Claim 14
Dependent Claim
26 words
A device according to claim 9, wherein preferably helically shaped guide ribs are provided at the walls of the pressing channel starting at the feed zone.
Claim 15
Dependent Claim
27 words
A device according to claim 9, wherein openings are provided in the base of the pressing channel at the lowermost point for the discharge of excessive fluid.
Claim 16
Dependent Claim
26 words
A device according to claim 9, wherein the mouthpiece has approximately the shape which corresponds to the natural cross-section of the supported silo mass of goods.
Claim 17
Dependent Claim
39 words
A device according to claim 9, wherein the mouthpiece is free to all sides for receiving a plastic cover foil and at its end a projecting edge and adjacent thereto a cover holder arranged for holding said cover foil.
Claim 18
Dependent Claim
30 words
A device according to claim 2, wherein the boundary wall has approximately an inclined and/or arch-shaped form which corresponds to the natural form of the stored silo mass of material.
Claim 19
Dependent Claim
51 words
A device according to claim 16, wherein the plastic cover foil constructed as a covering is tied shut, rolled in or welded shut at the ends of the silo mass of material and one or several ventilating pipes or relief pressure valves are provided for relieving the pressure within the mass.
Claim 20
Dependent Claim
23 words
A device according to claim 1, wherein in the forming channel the pressing device has one or several inclined upwardly divided press plungers.
Claim 21
Dependent Claim
46 words
A device according to claim 19, wherein the drive of the pressing device is done directly by an electric motor with a step-down gearing or a hydraulic motor fed by the tractor hydraulic system or by the tractor power take off shaft through a drive shaft.
Claim 22
Dependent Claim
28 words
A device according to claim 20, wherein the pressing device is driven by the tractor power take off shaft through a transmission gearing arranged on a harvesting wagon.
Claim 23
Independent Claim
