Abstract

Machine for removing potatoes and other tubers, driven by motoazada, which is essentially characterized by being constituted by a metal frame determined by two beams, which, at one end, are attached to a common crossbar, while the opposite are carriers of two axles adjustable in height and equipped with rear wheels and side guiding, being attached to the crossbar a frame in which are placed two traction side wheels and coming articulated on the crosspiece itself an arc laminar piece, angularly movable and joined by its lower part to a plurality of rods, there being in the middle part of the aforementioned beams a joint for two arms of a bridge element, which, at their low end, are articulated to an arched support carrying other rods, that act in combination with others suspended through articulated arms and another element in arc, of the propi The stringers, while their high section, are combined with a lever combined with a crankshaft, rotating by means of a chain and toothed pinions, of which the latter is coupled to the axis of the power take-off of the motor-cultivator, which is coupled to said frame, the aforementioned bridge component being also linked to said arc piece through a set of levers so that the action of the crankshaft gives rise to the opposite displacement of the sets of lower rods, all this so that while that arched piece causes the uprooting of the tubers, the mobile rods act as a sieve for the fall of the earth and to leave the potatoes or similar on the ground and aligned behind the machine.
