Abstract
Abstract An apparatus for separation of beets and stones by dry means, which comprises an endless continuously moving separation band including a conveyor run. The conveyor run runs substantially in horizontal direction and is equipped with cam-or fingerlike driver elements disposed about perpendicularly to the surface of the conveyor run and elastically bendable merely by specific heavy stones. A feeding device is disposed at one end of the separation band and two striper brushes are disposed one behind the other above the conveyor run and driven in the same direction of rotation as the separation band. The striper brushes have bristles including points of the latter, and knob points of the fingerlike driver elements have a distance from the bristle points smaller than the thickness of the beets. The feeding device comprises means for feeding intermittently the goods to be conveyed directly to one end of the separation band. The separation band and the striper brushes are obliquely inclined crosswise to the direction of movement and, the rotary axes of the brushes converge with the lower disposed edge of the conveyor run in the direction of movement of the latter and in at least one plane about parallel to the conveyor run.

Claim 1
Independent Claim
201 words
An apparatus for separation of beets and stones by dry means, comprising an endless continuously moving separation band, including a conveyor run, said conveyor run running substantially in horizontal direction and being equipped with cam-or fingerlike driver elements including knob points disposed about perpendicularly to the surface of said conveyor run and elastically bendable merely by the specific heavy stones, a feeding device at one end of said separation band, two striper brushes disposed one behind the other above said conveyor run and driven in the same direction of rotation as said separation band, said striper brushes having bristles including points of the latter, said bristle points having a distance from said knob points of said fingerlike driver elements smaller than the thickness of said beets, said feeding device comprising means for feeding intermittently the goods to be conveyed directly to said one end of said separation band, said separation band and said striper brushes being obliquely inclined crosswise to the direction of movement and, the rotary axes of said brushes converging with the lower disposed edge of said conveyor run in the direction of movement of the latter and in at least one plane about parallel to the conveyor run.
Claim 2
Independent Claim
201 words
An apparatus for separation of beets and stones by dry means, comprising an endless continuously moving separation band, including a conveyor run, said conveyor run running substantially in horizontal direction and being equipped with cam-or fingerlike driver elements including knob points disposed about perpendicularly to the surface of said conveyor run and elastically bendable merely by the specific heavy stones, a feeding device at one end of said separation band, two striper brushes disposed one behind the other above said conveyor run and driven in the same direction of rotation as said separation band, said striper brushes having bristles including points of the latter, said bristle points having a distance from said knob points of said fingerlike driver elements smaller than the thickness of said beets, said feeding device comprising means for feeding intermittently the goods to be conveyed directly to said one end of said separation band, said separation band and said striper brushes being obliquely inclined crosswise to the direction of movement and, the rotary axes of said brushes converging with the lower disposed edge of said conveyor run in the direction of movement of the latter and in at least one plane about parallel to the conveyor run.
Claim 3
Dependent Claim
44 words
The apparatus, as set forth in claim 1, which includes means for transfering said brushes into different angular positions relative to a central longitudinal line of said conveyor run, as well as into different angular positions to the conveyor face of said conveyor run.
Claim 4
Dependent Claim
54 words
The apparatus as set forth in claim 1, wherein said bristle points of the second of said striper brushes seen in the direction of movement of said beets have a smaller distance from said points of said fingerlike driver elements than the distance from the bristle points of the first of said striper brushes.
Claim 5
Dependent Claim
46 words
The apparatus, as set forth in claim 3, wherein the distance between said points is adjustable, and said distance from said points of said first striper brush amount to about 30-80 mm. and from said points of said second striper brush amounts to about 5-40 mm.
Claim 6
Dependent Claim
26 words
The apparatus, as set froth in claim 3, wherein said bristles of said first striper brush are markedly stiffer than those of said second striper brush.
Claim 7
Dependent Claim
36 words
The apparatus, as set forth in claim 3, wherein the numbers of revolution of said brushes are endlessly controllable independently from each other, and said second brush rotates with greater peripheral speed than said first brush.
Claim 8
Dependent Claim
31 words
The apparatus, as set forth in claim 6, wherein said converging angle between the axis of said striper brushes and the lower disposed conveyor run edge amounts to about 45-75* .
Claim 9
Dependent Claim
30 words
The apparatus, as set forth in claim 1, wherein said feeding device comprises a cell roller feeding the goods to be separated onto said separation band from a low height.
Claim 10
Dependent Claim
62 words
The apparatus, as set forth in claim 1, wherein two of said separation bands are provided which move parallel relative to each other and inclined rooflike of V-shaped relative to each other crosswise to the direction of conveyance and inclined relative to the horizontal, and said feeding device operating jointly for both of said bands and interMittently is coordinated to said bands.
Claim 11
Dependent Claim
60 words
The apparatus, as set forth in claim 3, which includes means disposed between said striper brushes for transferring the goods from the range of the lower disposed edge of said conveyor run in the direction towards the higher disposed edge, and said transferring means include conveyor fingers striking over the range of said lower disposed edge of said conveyor run.
Claim 12
Dependent Claim
35 words
The apparatus, as set forth in claim 3, which includes a turning device in form of a brush ledge disposed between the two striper brushes and aligning said beets crosswise to the direction of conveyance.
Claim 13
Dependent Claim
41 words
The apparatus, as set forth in claim 3, which includes a spreading device in form of a rotatable brush disposed at about 90* to the direction of conveyance and arranged between said feeding device and the first of said striper brushes.
