  • Patent number: 10745875
    Abstract: In one embodiment, a hopper spreader apparatus for spreading granular material is provided. The hopper spreader apparatus includes a hopper, a spreading unit, and a dispensing unit. The hopper has a storage cavity for storing the granular material to be spread. The spreading unit spreads the granular material. The dispensing system transports the granular material from the hopper to the spreading unit. The dispensing system includes a conveying unit and a rotating first roll. The conveying unit conveys the granular material toward the spreading unit. The rotating first roll controls a flow of granular material from the hopper to the conveying unit.

  • Patent number: 10736263
    Abstract: A spreader includes a frame having wheels mounted on an axle. A gear assembly on the axle is coupled with a shaft. A hopper is mounted on the frame and holds particulate that empties through an opening within the bottom wall. An impeller is mounted on the shaft and receives the particulate emptied from the hopper. A controlled-release assembly is mounted about the shaft and includes a drive housing secured to the hopper. The drive housing has a funnel opening to dispense the particulate therethrough. A transfer wheel within the drive housing is rotatably coupled to the shaft. When the shaft is rotating, the transfer wheel rotates whereby the particulate is delivered to the funnel. When the shaft is stationary, the transfer wheel is stationary whereby particulate is not delivered to the funnel.
