Example Embodiment

[0027] Example 1:

[0028] Attached Figure 1-3 As shown, a centrifugal drug spraying multi-rotor drone includes a multi-rotor drone fuselage 1, an arm 2 and a motor base 4 fixedly connected to the arm 2, and the motor base 4 is detachable below Fixed connection with sprinkler system 6, as attached image 3 As shown, the spray head system 6 includes a cylindrical shell 64 with an opening on the side wall and an impeller 61 for atomizing medicine. The motor base 4 is equipped with a double output end 42 and a lower output end 43. The head motor 41, the upper output end 42 is equipped with a rotor 5 for providing lift, and the lower output end 43 is drivingly connected to the impeller 61; a storage bin 3 with a pressure pump is installed under the fuselage 1 , The storage bin is provided with a medicine inlet at the top and a medicine outlet at the bottom. A delivery pipe 8 for communication is provided between the medicine outlet and the opening of the housing 64; the pressure pu...

Example Embodiment

[0035] Example 2:

[0036] On the basis of Example 1, combined with Figure 4 , 5 As shown, further, a screen 63 with a central hole is installed inside the housing 64, the edge of the screen is a solid ring, and a porous screen wall 62 is fixed on the solid ring. The hole diameter of the wall 62 is larger than the hole diameter of the screen 63.

[0037] An annular cavity is formed between the porous screen wall 62 and the housing 64, the pressurizing pump in the storage bin 3 works, the liquid medicine is pumped to the nozzle system 6 through the delivery pipe 8, and the liquid medicine enters the housing 64 The annular cavity between the porous screen wall 62 and the porous screen wall 62 evenly seeps out through the pores around the porous screen wall 62. Since the hole diameter of the porous screen wall 62 is larger than that of the screen 63, the screen The water inflow of the mesh 63 is greater than the water outflow. There is a certain depth of syrup stored on the sieve 63...

Example Embodiment

[0038] Example 3:

[0039] On the basis of embodiment 1 or 2, combined with figure 1 , 6 7. As shown in 7, the storage bin 3 is in the form of an inverted cone or a regular polygonal pyramid. The lowermost end of the storage bin 3 is provided with a medicine outlet, and a spherical branch 7 is installed on the medicine outlet. The branch 7 includes a hollow spherical cavity, a main pipe connected to the medicine outlet, and a branch pipe connected to the delivery pipe 8.

[0040] By setting the storage bin 3 as an inverted cone or a regular polygonal pyramid, the center of gravity of the storage bin 3 is always located at the center of the drone's fuselage no matter how much the potion is stored, so as to prevent the drone's center of gravity from being unstable At the same time, a medicine outlet is provided at the lower end of the storage bin 3 to facilitate the output of the medicine, and a spherical branch 7 is installed at the medicine outlet. The water pressure at each branch...

Abstract

The invention discloses a centrifugal farm-chemical spraying multi-rotor unmanned aerial vehicle (UAV). The centrifugal farm-chemical spraying multi-rotor UAV comprises a vehicle body, vehicle arms and a motor seat; a spraying head system is connected to the motor seat and comprises a shell body and impellers for atomizing farm-chemicals; a double-head motor is mounted in the motor seat and is in driving connection with rotor wings and the impellers; a storage bin provided with a pressure pump is mounted below the vehicle body, and a conveying pipe is arranged between the storage bin and the shell body; and a switch module is mounted on the pressure pump and is connected with a controlling module of the UAV. The characteristics of being small in carrying weight and high in flight maneuverability of the multi-rotor UAV are utilized, the centrifugal farm-chemical spraying multi-rotor UAV is suitable for farm-chemical spraying in a small and medium-sized farmland, and emphasizing spraying can be achieved; the motor is arranged as the double-head motor, on the basis of no adding a driving device, the high-speed rotating impellers are utilized to atomize and spray medicinal liquid, manual labor is replaced, cost is reduced, field ditches used for walking is not required to be reserved in the farmland, and the utilization rate of the farmland is improved.

Description

technical field [0001] The invention relates to the field of agricultural unmanned aerial vehicles, in particular to a centrifugal drug spraying multi-rotor unmanned aerial vehicle. Background technique [0002] UAV is the abbreviation of "unmanned aircraft", and the English abbreviation is "UAV". It is an unmanned aircraft controlled by radio remote control equipment and its own program control device. The concept of drones first appeared in the 1920s. With the rapid development of science and technology, the technology of drones has become more and more mature, and the application of drones has gradually entered the public eye. , drones + industry applications are the real needs of drones today. [0003] In traditional agricultural production, farmers fertilize, spray pesticides, and prevent pests and diseases based on experience. During the operation, they must do everything on each piece of land and crops. This extensive operation method is intensive, inefficient, and ...
