Nozzle attitude controller for spot and variable rate application of agricultural chemicals and fertilizers
First Claim
1. A farming apparatus for precision farming comprising:
- an applicator vehicle;
a plurality of variable rate applicators supported by said vehicle, said applicators constituting spaced nozzles mounted to a rotatable manifold, means for rotating said manifold so as to change the attitude of said nozzles to where the horizontal component of the jet velocity from the nozzles is equal and opposite to that of the applicator vehicle.

Abstract
A nozzle attitude controller for use in connection with a farming apparatus for precision farming, the apparatus comprising an applicator vehicle, a boom supported by and extending across the rear of the vehicle, a manifold rotatably supported by the boom, a plurality of nozzles disposed from the manifold and oriented in a direction opposite to the direction of movement of the vehicle, but disposed at an angle with respect to the horizontal, the attitude controller including a linear actuator operated by a stepper motor and a radar sensor which connects to the stepper motor and which measures the speed of the vehicle such that pulses from the radar sensor to the stepper motor moves the linear actuator to change the angle of the nozzle so that the horizontal component of its velocity is equal and opposite to the speed of the vehicle.

- 3. A variable rate applicator system adapted to be supported from a boom extending from the rear of an applicator vehicle comprising a rotatable manifold connected to the boom, a plurality of nozzles attached to the manifold in spaced relation for the purpose of spraying a solution onto the ground, a rotation means connected to the boom and to the manifold for rotating the manifold thereby to vary the angle of the nozzle with respect to the horizontal, means for moving said rotation means in response to the speed of the vehicle to change the angle of the spray nozzle with respect to the horizontal so that the horizontal component of the spray velocity is equal and opposite to the velocity of the vehicle.
