Abstract
Abstract A device for impact breaking up of compressed material packed in a sack includes a frame and means to support a driving and vibrating assembly of the device. A vibrating element or tunnel is inclined and is formed by the joining of two rigid bodies having concave U-shaped cross sections, the respective concavities of the bodies being face to face and having therebetween interchangeable vibration absorbing separators. The upper body has a shorter length and has, at one of its ends, a roller which may turn freely and whose height may be regulated, while the lower body has, on its wide external face, suitable supports for the vibrating assembly. The vibrating and supporting means of the vibrating assembly are elastic bodies arranged in pairs.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A device for breaking up by vibration impact compressed material packed in a sack, said device comprising: a base mountable on a foundation; a vibrating tunnel assembly having an inlet and an outlet; a plurality of supporting means including pairs of coil springs and leaf springs for resiliently supporting said vibrating tunnel assembly above said base in an inclined manner with said outlet lower than said inlet; vibrating means mounted on said base and connected to said vibrating tunnel assembly for imparting a vibrating motion thereto; and said vibrating tunnel assembly comprising: an upper tunnel forming member having a first longitudinal length and a U-shaped concave transverse cross-section; a lower tunnel forming member having a second longitudinal length greater than said first longitudinal length and a Ushaped concave transverse cross-section; said upper and lower members being joined with the concavities thereof confronting each other; a roller freely rotatably positioned adjacent said outlet; and means attached to said upper member for mounting said roller.
Claim 2
Independent Claim
163 words
A device for breaking up by vibration impact compressed material packed in a sack, said device comprising: a base mountable on a foundation; a vibrating tunnel assembly having an inlet and an outlet; a plurality of supporting means including pairs of coil springs and leaf springs for resiliently supporting said vibrating tunnel assembly above said base in an inclined manner with said outlet lower than said inlet; vibrating means mounted on said base and connected to said vibrating tunnel assembly for imparting a vibrating motion thereto; and said vibrating tunnel assembly comprising: an upper tunnel forming member having a first longitudinal length and a U-shaped concave transverse cross-section; a lower tunnel forming member having a second longitudinal length greater than said first longitudinal length and a Ushaped concave transverse cross-section; said upper and lower members being joined with the concavities thereof confronting each other; a roller freely rotatably positioned adjacent said outlet; and means attached to said upper member for mounting said roller.
Claim 3
Dependent Claim
20 words
A device as claimed in claim 1, further comprising longitudinal vibration absorbing strips interposed between said upper and lower members.
Claim 4
Dependent Claim
52 words
A device as claimed in claim 1, wherein one of the longitudinal ends of each of said upper and lower members being substantially aligned to form said outlet, and the opposite longitudinal end of said lower member extending beyond the opposite longitudinal end of said upper member to form a loading area.
Claim 5
Dependent Claim
96 words
A device as claimed in claim 3, wherein said vibrating tunnel assembly further comprises a first plurality of flat plates positioned end-to-end at angles to each other to form a first wave-shaped element extending longitudinally within said upper member, and a second plurality of flat plates positioned end-to-end at angles to each other to form a second wave-shaped element extending longitudinally within said lower member, said first and second wave-shaped elements being spaced from each other to form therebetween a zig-zag shaped channel extending longitudinally of said vibrating tunnel assembly from said inlet to said outlet.
Claim 6
Dependent Claim
15 words
A device as claimed in claim 4, wherein said flat plates have a trapezoidal shape.
Claim 7
Dependent Claim
19 words
A device as claimed in claim 4, wherein said second wave-shaped element does not extenD into said loading area.
