Abstract
An apparatus for removing ice and snow from a surface consisting of a support frame and a elongate member rotatably mounted on the support frame. The elongate member has a first end and a second end. A plurality of flexible arms extend from the elongate member in a substantially helical pattern. Upon rotation of the elongate member the arms violently strike a ground surface to dislodge packed snow and ice which is then carried by the helical pattern of the arms from the first end of the elongate member toward the second end.
Claims17
An apparatus for scraping a ground surface, comprising;
- a support frame;
- a hub member rotatably mounted on the support frame for rotation about a substantially horizontal axis;
- drive means for driving the rotation of the hub member in a direction of rotation;
- a plurality of flexible arms mounted on the hub member at angularly spaced positions around the axis for rotation therewith, the arms extending substantially radially from the axis such that an outer end of each arm can effect engagement with the ground surface in a scraping action;
- and a flexible flap member mounted on the hub member so as to extend outwardly therefrom substantially in an axial plane of the hub member and alongside at least one of the flexible arms.

- a plurality of flexible arms mounted on the hub member at angularly spaced positions around the axis for rotation therewith, the arms extending substantially radially from the axis such that an outer end of each arm can effect engagement with the ground surface in a scraping action;
- and a plurality of rigid support plates mounted on the hub member at angularly spaced positions therearound so as to extend substantially radially outwardly therefrom, each plate including a first portion extending substantially radially outwardly from the hub member to which at least a respective one of the flexible arms is clamped and a second portion outward of the first portion inclined outwardly and rearwardly relative to the direction of rotation of the hub member.
