Three-groove steering engine driven gear and rack type unmanned aerial vehicle-mounted continuous dispenser

The invention provides a gear and rack type unmanned aerial vehicle-mounted continuous dispenser driven by a three-groove steering engine, and aims at solving problems that an existing unmanned aerial vehicle is low in dispensing efficiency and low in space utilization rate. The device is structurally composed of a fixing plate component, a dispenser main body component, a rack push rod component, a straight gear and a steering engine, wherein a long fixing hole in the fixing plate is formed in a protruding end of a convex plate to fix the fixing plate to the unmanned aerial vehicle; every two of the three holes are combined on the convex plate according to functional requirements, and the dispenser main body part is fixed through a locking nut; the dispenser main body is fixed by a connecting area and a short fixing hole in the dispenser main body component through a locking nut; a front pair of screw holes and a rear pair of screw holes are formed in the steering engine fixing area to fix a steering engine;
