Ice pulverizing knife and ice pulverizing device comprising an ice pulverizing knife

An ice pulverizing knife for pulverizing ice from a ground surface, the ice pulverizing knife comprising:

• a frame having a substantially circular base defining a first diameter, the frame comprising:
• a top defining a second diameter smaller than the first diameter, the top having a socket, the socket being adapted for mechanically coupling the frame with a vertical drive shaft, a rotation of the vertical drive shaft resulting in a circular rotation of the frame,
• the base for engaging with the ice on the ground surface, and
• at least one opening between the top and the base;
• and
• a plurality of blades secured to the frame, each blade radially projecting away from-the frame radially along the base, each blade engaging with the ice on the ground surface for cutting the ice;
• wherein ice cut by the blade and accumulated inside the frame is expelled from the frame through the at least one opening.
