Abstract
Abstract A harvesting implement for harvesting of corn and other grain products, to be arranged in front of a harvester thresher, comprises a driven drawing roller having a substantially cylindrical main body and a plurality of impact plates provided with cutouts, a cutting block provided with cutting elements extending through the cutouts, and a counter holder associated with the drawing roller. The counter holder is formed as a driven counter roller which is axes parallel to the picking roller, the counter roller includes a main body with a plurality of segments spaced from one another, the drawing roller and the counter roller are both associated with the one common cutting block, the cutting elements of the cutting block include a plurality of cutters which extend simultaneously in the intermediate spaces between the segments of the counter roller and in the cutouts of the impact plates of the drawing roller.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
A harvesting implement for harvesting of corn and other grain products, to be arranged in front of a harvester thresher, the harvesting implement comprising for each a plant row driven drawing roller having a substantially cylindrical main body and a plurality of impact plates provided with cutouts; a cutting block provided with cutting means extending through said cutouts; and a counter holder associated with said drawing roller, said counter holder being formed as a driven counter roller which is axes parallel to said drawing roller, said counter roller including a main body with a plurality of segments spaced from one another, said drawing roller and said counter roller being both associated with said one common cutting block, said cutting means of said cutting block including a plurality of cutters which extend simultaneously in intermediate spaces between said segments of said counter roller and in said cutouts of said impact plates of said drawing roller.
Claim 2
Dependent Claim
154 words
A harvesting implement for harvesting of corn and other grain products, to be arranged in front of a harvester thresher, the harvesting implement comprising for each a plant row driven drawing roller having a substantially cylindrical main body and a plurality of impact plates provided with cutouts; a cutting block provided with cutting means extending through said cutouts; and a counter holder associated with said drawing roller, said counter holder being formed as a driven counter roller which is axes parallel to said drawing roller, said counter roller including a main body with a plurality of segments spaced from one another, said drawing roller and said counter roller being both associated with said one common cutting block, said cutting means of said cutting block including a plurality of cutters which extend simultaneously in intermediate spaces between said segments of said counter roller and in said cutouts of said impact plates of said drawing roller.
Claim 3
Dependent Claim
47 words
A harvesting implement as defined in claim 1, wherein said drawing roller and said counter roller have axes which are spaced from one another by a predetermined distance, said distance being smaller than a sum of radii of circumferences of said drawing roller and said counter roller.
Claim 4
Dependent Claim
41 words
A harvesting implement as defined in claim 1, wherein each segment of said counter roller has at least three vanes, said vanes having vane portions operating for drawing and inclined rearwardly relative to a direction of rotation of said counter roller.
Claim 5
Dependent Claim
22 words
A harvesting implement as defined in claim 3, wherein said vane portions of said vanes are inclined rearwardly in an arcuate fashion.
Claim 6
Dependent Claim
25 words
A harvesting implement as defined in claim 1, wherein said drawing roller and said counter roller are each provided with front tips having helical plates.
Claim 7
Dependent Claim
22 words
A harvesting implement as defined in claim 5, wherein said tips of said drawing roller and counter roller have a conical shape.
Claim 8
Dependent Claim
30 words
A harvesting implement as defined in claim 1, wherein a diameter of a circumference of said counter roller is smaller than a diameter of a circumference of said drawing roller.
Claim 9
Dependent Claim
44 words
A harvesting implement as defined in claim 1, wherein said drawing roller and said counter roller are arranged so that a vertical central plane between said drawing roller and said counter roller is laterally offset toward a vertical central plane of said drawing roller.
Claim 10
Dependent Claim
24 words
A harvesting implement as defined in claim 1, wherein said drawing roller has four said impact plates, said counter roller having six said vanes.
Claim 11
Dependent Claim
37 words
A harvesting implement as defined in claim 1; and further comprising means for driving said counter roller and said drawing roller, so that said counter roller is driven with a higher rotary speed than said drawing roller.
Claim 12
Dependent Claim
39 words
A harvesting implement as defined in claim 1; and further comprising means for driving said counter roller and said drawing roller so that a ratio of rotary speeds of said counter roller and said drawing roller amount to 4:3.
Claim 13
Dependent Claim
38 words
A harvesting implement as defined in claim 1, wherein said cutting means include a plurality of rollers having a freely rotatable region and corresponding in said region to a radius of said main body of said counter roller.
Claim 14
Dependent Claim
38 words
A harvesting implement as defined in claim 1, wherein said cutting means include a plurality of rollers having a freely rotatable region and corresponding in said region to a radius of said main body of said drawing roller.
Claim 15
Dependent Claim
23 words
A harvesting implement as defined in claim 1, wherein said cutting means include a plurality of cutters each provided with a reinforcing crease.
Claim 16
Dependent Claim
31 words
A harvesting implement as defined in claim 1; and further comprising a holder for said cutting block, said holder being laterally offset outwardly toward said main body of said counter roller.
