Cotton topping unmanned aerial vehicle having cutter discs and front grain lifting baffle plates

A cotton topping unmanned aerial vehicle having cutter discs and front grain lifting baffle plates, comprising an unmanned aerial vehicle body, a carrying component, a grain lifting component and a cutting component, wherein the carrying component, the grain lifting component and the cutting component are all carried and fixed on the unmanned aerial vehicle body;

• the carrying component comprises a suspension, an electric push rod mounting base, an electric push rod, a motor mounting base and motors, wherein the suspension is bolted to the bottom of the unmanned aerial vehicle body, the electric push rod mounting base is bolted to the suspension and configured for mounting the electric push rod, an upper end of the electric push rod is bolted to the electric push rod mounting base to enable extending and retracting of the grain lifting component and the cutting component so as to facilitate taking off and landing of the unmanned aerial vehicle, the motor mounting base is welded to a lower end of the electric push rod;
• the motor mounting base is configured for mounting the motors on the one hand, and on the other hand, has a flow guiding function to reduce the disturbance on cotton tops to be cut caused by a downward pressure wind field of the unmanned aerial vehicle body, each of the motors is bolted to the motor mounting base, the motors are powered by a power supply of the unmanned aerial vehicle body, output shafts of the motors are connected with a cutter disc set which is configured for cutting the cotton tops, and a number of motors is two;
• the grain lifting component is grain lifting baffle plates which comprise a left baffle plate and a right baffle plate, both the left baffle plate and the right baffle plate are welded to guard plates, the grain lifting baffle plates is configured for gathering the cotton tops to be cut;
• the cutting component comprises the guard plates and the cutter disc set, wherein the guard plates are welded to housings of the motors and configured for protecting the cutter disc set, the number of guard plates is two, the cutter disc set is formed by a pair of cutter discs which rotate in opposite directions and have vertical gap therebetween and are configured for cutting the cotton tops, the cutter discs each are provided with a circle of cutter teeth, and by virtue of relative rotation between the cutter teethes on the cutter disc set, cotton stalks are cut, and the cotton tops cut are brought to a rear of the unmanned aerial vehicle in a forward direction.
