SMALL-SIZED POTATO HARVESTER WITH A CATERPILLAR DRIVE Russian patent published in 2014 - IPC A01D17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine industry. The harvester contains the arc-shaped digger shovel, separating device, vine separator belts, the branches of which with an interval 12 cm are pressed to potato intake elevator. The separating device consists of chaffer lifting and potatoe intake elevators. The lower carrier frame of the harvester by means of rigid height-adjustable suspension brackets, rests on the bar of basic rollers of hingeless rubber caterpillar drive. The forward driven and back guiding sprockets of the caterpillar drive are installed on the carrier frame. The forward sprockets are fixed on the ends of the common shaft, in the average part of which the sprocket is located, from which using the chain the motion is transmitted through the countershaft with sprockets to the driving shafts of the elevator. Ends of axles of back guiding sprockets are fixed to the slides put on the frame bar and equipped with amortisation springs and adjusting screws.

EFFECT: keeping the set kinematic mode of the separating working member is ensured at variation of translational speed of the unit, the unit operation is facilitated, the possibility of the unit operation at higher speed is possible.
