ABSTRACT:
A hydrostatic spraying system with multiple spray booms for use with vehicles is especially suited for spraying agricultural treatment liquids such as fertilizers, herbicides, insecticides, trace minerals, etc. The system includes an operator-controllable variable displacement hydraulic pump driven by the vehicle, e.g., via its transfer case. A linear hydraulic motor is powered by the pump, being operated at a speed dependent upon a preselected output of the variable displacement pump and the rate of ground travel. Solenoid-controlled valving alternately supplies the hydraulic fluid to opposite ends of the linear motor for oscillating stroking operation of the motor. Twin linear hydraulic pumps interconnected with the linear motor each draw treatment liquid from a liquid supply tank and deliver treatment liquid under pressure in a precisely metered amount upon each stroke of the linear motor through corresponding operator-controlled diverter valves which are selectively operable to permit the metered amounts of treatment liquid to flow to respective spray booms or to be returned to the supply tank in a sparging line connection. The metered amounts delivered by each linear pump for delivery by the spray booms may be determined and totalled accurately by counters.
