  • Apparatus for spreading granular and liquid materials
    Patent number: 5186396
    Abstract: A granular and liquid material spreading system mounted on a vehicle. Granular material is moved from a hopper to a delivery system using hydraulic pumps and motors. The hydraulic system also drives a liquid delivery system. A control system including a material computer is provided to control the amount of granular material and liquid material applied to a surface. The feed rate of liquid delivery is controlled electronically by programming the material computer as a function of the feed rate of the granular material. The liquid feed rate may be changed within a predetermined range. The level of liquid may be sensed to disengaged the liquid delivery system. Initiation of liquid delivery reduces the feed rate of granular material by a variably selected percentage.

  • Apparatus for synchronized spreading of granular and liquid material
    Patent number: 5096125
    Abstract: A granular and liquid material spreading system mounted on a vehicle. Granular material is moved from a hopper to a delivery means using hydraulic pumps and motors. The hydraulic system also drives a liquid delivery system. A control system is provided to control the amount of granular material and liquid material applied to a surface. The feed rate of liquid delivery is dependent upon the feed rate of the granular material. The liquid feed rate may be changed within a predetermined range. The level of liquid may be sensed to disengage the liquid delivery system. Initiation of liquid delivery reduces the feed rate of granular material by a variably selected percentage.

  • Synchronized granular material and liquid spreading device with full hydraulic control
    Patent number: 5069392
    Abstract: A granular and liquid material spreading system mounted on a vehicle is disclosed. Granular material is moved from a hopper to delivery means by a hydraulic system. The hydraulic system for a granular material delivery system is selectively used by a liquid delivery system to operate a liquid pump to move the liquid material to the delivery position. The amount of liquid delivered is dependent upon the feed rate of the granular material delivery system. Variation of the liquid feed rate may be changed within a predetermined range. The level of liquid may be sensed to disengage the liquid delivery system. In one embodiment, the hydraulic system fluid is diverted to power the liquid delivery system, slowing the feed rate of the granular delivery system and the amount of granular material used. In another embodiment the hydraulic system is used to control the liquid feed rate.
