Vane, mounting assembly and throwing wheel apparatus having a locking member tapered in two planes

摘要

A vane of a throwing wheel apparatus including a particle throwing portion, extending between first and second ends, having a first throwing face, a second throwing face, and two side edges. Each of the side edges extend substantially parallel to one another and includes a locking member adapted to be detachably coupled to a mounting element of the throwing wheel apparatus. Each locking member includes a first taper in a first plane and a second taper in a second plane. The first plane is substantially perpendicular to each side edge of the vane and the second plane is substantially parallel to the first taper. The side edges define a width smaller than a predetermined distance between first and second mounting elements of the throwing wheel apparatus so that when coupled to the mounting elements a gap is present on both sides of the vane.
