ROOT AND TUBER TRANSPORTATION AND SEPARATION DEVICE Russian patent published in 1997 - IPC

FIELD: agricultural engineering; potato harvesters. SUBSTANCE: working conveyor provided with sides 2 is secured on stepped frame 1. Conveyor consists of row of separating drums 3. Bases of drums 3 are made in the form of elliptic plates 4. Side surface of drum is formed by uniformly spaced rods 6. Additional elliptic plate 5 is arranged in middle portion of each drum 3. Separating drums 3 are installed in tandem so that larger axes of elliptic plates 4, 5 of any adjacent drums are relatively perpendicular and additional plates 5 of these drums 3 are displaced through equal distances in opposite directions relative to longitudinal axis of working conveyor. Mechanical ties 10, 11 designed to transmit rotation from foregoing drum to the following drum are made on opposite ends of drums. First driving drum is arranged in first third of row in direction of operation steps. EFFECT: increased capacity at root and tuber harvesting, improved separation, possibility of operation at soil moisture exceeding 28%. 3 dwg
