Abstract: The present specification relates to an ice-pulverizing knife for pulverizing ice from a ground surface, and to an ice-pulverizing device equipped therewith. The ice-pulverizing knife comprises a frame and a blade. The frame has a substantially circular base, and comprises a top, a base, at least one opening, a slot and a shoulder. The top has a socket 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 top has a first diameter. The base engages with the ground surface and has a second diameter greater than the first diameter. The at least one opening is positioned between the top and the base. The slot defines an aperture along the base. The shoulder is adjacent the slot and comprises a securing mechanism. The blade is adapted for insertion in the slot and affixing to the shoulder by means of the securing mechanism. When affixed to the shoulder, the blade projects towards the ground surface.

Abstract: The present specification relates to an ice pulverizing knife for pulverizing ice from a ground surface, and to an ice pulverizing device equipped therewith. The ice pulverizing knife comprises a frame and a plurality of blades. The frame has a substantially circular base and comprises a top, a base and at least one opening. The top has a socket adapted for mechanically coupling the frame with a vertical drive shaft. Rotation of the vertical drive shaft results in rotation of the frame. The base engages with the ice on the ground surface. The at least one opening is positioned between the top and the base. The plurality of blades is secured to the frame. Each blade radially projects from the frame and engages with the ice on the ground surface for cutting the ice. Ice cut by the blade and accumulated inside the frame is expelled from the frame through the at least one opening.

Abstract: An ice-removing device for removing ice from a ground surface. The ice-removing device comprises a frame and an ice cutting mechanism. The ice cutting mechanism is attached to the frame and is adapted to spin on a first axis oriented transversally to the frame. The ice cutting mechanism is operative to cut a plurality of parallel strips in the ice. Optionally, the ice-removing device further comprises at least one ice crushing mechanism, which is also attached to the frame, behind the ice crushing mechanism. The ice crushing mechanism is adapted to spin on a second axis that is non-parallel to the first axis. Both the ice cutting mechanism and the ice crushing mechanism are operationally positioned to contact the ice. In another embodiment the ice-removing device is adapted to be mounted to a mobile support.
