ABSTRACT:
A direct injection chemical sprayer for spraying a fluid mixture onto a field as the sprayer is moved over the field. The sprayer includes a chemical pump mechanism for pumping chemicals from a chemical tank, a sensing mechanism for sensing the speed at which the sprayer is being moved over the field, and a drive mechanism operatively coupled to the sensing mechanism and to the chemical pump for varying the output of the chemical pump mechanism in proportion to the speed at which the sprayer is being moved over the field. A second embodiment includes self-contained replaceable cartridges each of which has a tank, a pump, drive mechanism therefor, and calibration apparatus. There are removable intermediate gear boxes and a main gear box, each of which has a plurality of selectable drive mechanisms for driving the pump of the gear box at a selected speed. A third embodiment includes a detachable frame for removably mounting on a tractor and a hydraulic drive mechanism including a master drive mechanism and a slave drive mechanism for driving the input shaft of the main gear box.
