ABSTRACT:
The invention is a cement mixer sand spreader for applying a sand mixture to a roadway to enhance friction for motorized traffic passing over the roadway and to simultaneously lower a freezing temperature of the ice and/or snow on the roadway. One form of the invention includes two major components. The first is a self-propelled cement mixer vehicle having a powered barrel for rotatably storing the sand mixture, wherein the barrel defines a discharge outlet for discharging the sand mixture upon rotation of the barrel in a discharge direction. The second is a sand spreader having a hopper secured adjacent the discharge outlet of the cement mixer for receiving the sand mixture discharged out of the barrel, the sand spreader also having a powered spinner plate rotatably secured adjacent a discharge end of the hopper for spreading the sand mixture over a roadway whenever the sand mixture passes through the hopper and contacts the rotating spinner plate. In other forms of the invention, the cement mixer sand spreader also includes a drop chute positioned between the hopper and spinner plate, wherein the drop chute is detachable from the hopper to facilitate securing the sand spreader to the cement mixer. The drop chute may also include a mounting post dimensioned to slide into a standard pinnacle mount on known cement mixers, which pinnacle mount supports standard cement flow chutes secured to known cement mixers.
