Abstract
Improved impeller for tops, characterized essentially by the fact of being constituted by a tubular casing as a handle, for easy grasping, whose casing is integrated by two parts plugged under pressure, the largest of which comprises the dry batteries of power supply. An electromotor housed in the other part of the casing, provided this part with an end hole for output of the motor pto shaft, in the axial direction, whose axis is covered by a cylinder-conical head of elastic friction material, operatively ready to lodge in the cavity to the effect presented by the top, which is dragged in the turn.
