| 摘要 |
The invention relates to agricultural engineering, in particular to working elements of potato-harvesting machines. A roller cleaning unit has a shape of a semi-ring in longitudinal-vertical cross-section thereof. In said semi-ring from above an inlet opening is arranged, and in the lower part there are two outlet openings. The outer part of the semi-ring is also formed by driving rollers that have counter-rotating movements in pairs and consists of two symmetrical movable parts, in which the upper ends are kinematically connected to mechanisms of oscillatory movements in the vertical direction, and the lower ends are mounted on extension springs. |
