Abstract
A turning drum of self-propelling harvester thresher is arranged after a threshing mechanism and has a closed casing with a plurality of rows of ribs extending parallel to a rotary axis of the drum. The ribs are inclined by substantially 20.degree.-40.degree. relative to a traveling direction of the harvester thresher. Thereby, the grains which strike against the inclined ribs are deviated, and as a result their striking energy is reduced and the grain breakage is prevented.
Claims8
A turning drum for arranging in a self-propelling harvester thresher after a threshing mechanism operating in accordance with the principle of a tangential flow and before a separating and cleaning device, the turning drum comprising a closed casing;
- and a plurality of rows of ribs arranged on said casing, said ribs inclined so as to deviate a moving speed and a travelling direction of grains and to reduce striking energy of said grains moving from said threshing mechanism to said separating and cleaning device.
A turning drum for arranging in a self-propelling harvester thresher after a threshing mechanism operating in accordance with the principle of a tangential flow and before a separating and cleaning device, the turning drum comprising a closed casing having an outer surface and an axis of rotation;
- and a plurality of rows of inclined ribs arranged on casing, said ribs being arranged on said outer surface of said casing, said rows of ribs extending parallel to said axis of rotation of said casing, said ribs being arranged in each row at equal distances from one another, said ribs being inclined so as to deviate a moving speed and travelling direction of grains and to reduce striking energy of said grains moving from said threshing mechanism to said separating and cleaning device.
