DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present disclosure will be further explained in detail with reference to the drawings and embodiments.

[0017] Referring to FIG. 1 and FIG. 2, the present disclosure provides the cotton topping unmanned aerial vehicle having cutter discs and front grain lifting baffle plates, which includes an unmanned aerial vehicle body 1, a carrying component, a grain lifting component and a cutting component. The unmanned aerial vehicle body 1 is an electric unmanned aerial vehicle body. The carrying component, the grain lifting component and the cutting component are all carried and fixed on the unmanned aerial vehicle body 1.

[0018] The carrying component includes a suspension 2, an electric push rod mounting base 3, an electric push rod 4, a motor mounting base 5 and motors 6. The suspension 2 is bolted to the bottom of the unmanned aerial vehicle body 1. The electric push rod mounting base 3 is bolted to the suspension 2 for mounting the electric push rod 4. The upper end of the electric push rod 4 is bolted to the electric push rod mounting base 3 to enable the extending and retracting of the grain lifting component and the cutting component to facilitate taking off and landing of the unmanned aerial vehicle. The motor mounting base 5 is welded to the lower end of the electric push rod 4. The motor mounting base 5 is configured for mounting the motors 6 on the one hand, and on the other hand, has a flow guiding function to reduce the disturbance on the cotton top to be cut caused by the downward pressure wind field of the unmanned aerial vehicle body 1. The motor mounting base 5 is shaped as a square, and a side length of the square is 30 cm. Each of the motors 6 is bolted to the motor mounting base 5. The motors 6 are powered by the power supply of the unmanned aerial vehicle body 1. The output shafts of the motor 6 are connected with the cutter disc set 9 which is configured for cutting the cotton top, and the number of motors is 2.

[0019] The grain lifting component refers to the grain lifting baffle plates 8 which includes a left baffle plate and a right baffle plate. Both the left baffle plate and the right baffle plate are welded to guard plates 7. The grain lifting baffle plates 8 are configured for gathering the cotton top to be cut.

[0020] The cutting component includes guard plates 7 and the cutter disc set 9. The guard plates 7 are welded to a housing of the motors 6, for protecting the cutter disc set 9. The number of guard plates is 2. The cutter disc set 9 is formed by a pair of cutter discs which rotate in opposite directions, have a vertical gap and is configured for cutting the cotton top. The diameter of the cutter discs is 8 cm, the vertical gap is 1 mm, and the rotating speed is 15000 r/min. The cutter discs each are provided with a circle of cutter teeth, and by virtue of the relative rotation between the cutter teeth on the cutter disc set 9, it is convenient to cut cotton stalks while bringing the cut cotton top to the rear of the unmanned aerial vehicle in the forward direction.

[0021] The working process of the cotton topping unmanned aerial vehicle having the cutter discs and front grain lifting baffle plates is as follows. After the unmanned aerial vehicle body 1 is powered on and takes off, the electric push rod 4 in the carrying component extends to locate the grain lifting component and the cutting component below a tripod of the unmanned aerial vehicle body 1. The unmanned aerial vehicle body 1 adjusts the flying height and cutting position of the unmanned aerial vehicle body 1 through a GPS positioning system. The grain lifting baffle plates gather cotton branches, cotton leaves and cotton tops into the cutter disc set 9. The output shafts of motors drives the cutter discs to rotate at high speed in opposite directions to cut the cotton top. The guard plates 7 protect the cutter disc set 9 to prevent cotton branches and cotton leaves from winding around the cutter disc set 9.

[0022] Finally, it should be noted that the above embodiments are only used to show and describe the basic principles, main features and advantages of the present disclosure. Those skilled in the art should understand that the present disclosure is not limited by the above embodiments, and that there will be various modifications or equivalent substitutions without departing from the spirit and scope of the present disclosure, but any modifications or equivalent substitutions made without departing from the spirit and scope of the present disclosure should be included in the claims of the present disclosure.
