Claims29
A machine for removing roots and tops from crops, the machine comprising:
- a topping screen having a first end and a second end, the topping screen including at least one pair of counter-rotating rollers arranged in parallel and spaced apart so as to define a nip therebetween situated between the first end and the second end, and means for rotating the rollers;
- wherein
- at least one roller is in the form of a polygonal twisted prism.
A machine for removing roots and tops from crops, the machine comprising:
- a topping screen having a first end and a second end, the topping screen including at least one pair of counter-rotating rollers arranged in parallel and spaced apart so as to define a nip therebetween situated between the first end and the second end, and means for rotating the rollers;
- wherein
- the at least one pair of rollers comprises a roller in the form of a polygonal twisted prism and a cylindrical roller.
A machine for removing roots and tops from crops, the machine comprising:
- a topping screen having a first end and a second end, the topping screen including at least one pair of counter-rotating rollers arranged in parallel and spaced apart so as to define a nip therebetween situated between the first end and the second end, and means for rotating the rollers;
- wherein
- at least one roller is in the form of a polygonal twisted prism and wherein the nip is defined by contact between one or more sections of a long edge of the at least one roller in the form of a polygonal twisted prism and the other roller of the at least one pair.
