Driving mechanism for a separator

摘要

A separator (1) for separating tubers (14) from haulm (15) etc. and having at least one pair of parallel elongate rollers (2) arranged traversely to the direction of travel thereover of objects (e.g. tubers (14) and haulm (15)) to be separated. Above the rollers (2) is an endless belt (3) having an engaging reach for engagement with the tubers (14) on the rollers (2) so as to move the tubers (14) therealong. The rollers (2) are driven by a motor (29) through gear means (20), which are formed and arranged for selectively transmitting drive to the rollers (2) in a first condition so that the rollers (2) rotate in opposite directions and in a second condition so that the rollers (2) rotate in the same direction. A control means (60) is provided to allow selection of desired first and second conditions of the gear means (20). <IMAGE>
