Problems solved by technology

However, most of the existing drug spraying drones are fixed-wing drones. Fixed-wing drones must have a certain relative speed with the air to have lift to fly. Because of this principle, fixed-wing aircraft have a fast flight speed. , relatively economical, and has the characteristics of large carrying capacity. It is mostly suitable for large-scale farmland. If it is used for small-scale farmland, the cost will be higher, and it can only be used for indiscriminate spraying. Drug spraying drones in farmland, and can carry out focused spraying

Embodiment 1

[0028] combined with Figure 1-3 As shown, a centrifugal drug spraying multi-rotor UAV includes a multi-rotor UAV fuselage 1, a machine arm 2 and a motor base 4 fixedly connected to the machine arm 2, and the bottom of the motor base 4 is detachable Fixedly connected with sprinkler system 6, as attached image 3 As shown, the nozzle system 6 includes a cylindrical housing 64 with an opening on the side wall and an impeller 61 for atomizing medicine, and a double motor with an upper output end 42 and a lower output end 43 is installed in the motor base 4. Head motor 41, rotor 5 for providing lift is installed on the upper output end 42, and the lower output end 43 is drivingly connected with the impeller 61; a storage bin 3 with a booster pump is installed under the fuselage 1 , the top of the storage bin is provided with a drug inlet, and the bottom is provided with a drug outlet, and a delivery pipe 8 for communication is arranged between the drug outlet and the opening of t...

Embodiment 2

[0036] On the basis of Example 1, in conjunction with the attached 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 fixedly arranged on the solid ring, and the porous screen The aperture of the wall 62 is larger than the aperture of said screen 63 .

[0037] An annular cavity is formed between the porous sieve wall 62 and the housing 64 , the pressurized 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 and the annular cavity between the porous sieve wall 62, and then seep out evenly through the pores around the porous sieve wall 62, because the aperture of the porous sieve wall 62 is greater than the aperture of the screen 63, The water inflow of the net 63 is greater than the water outflow, and there is a certain depth of liquid medicine on t...

Embodiment 3

[0039] On the basis of embodiment 1 or 2, in conjunction with the attached figure 1 , 6 , 7, the storage bin 3 is an inverted cone or a regular polygonal pyramid, and the lowermost end of the storage bin 3 is provided with a drug outlet, and a spherical branch 7 is installed on the drug outlet. Brancher 7 includes a hollow spherical cavity, a main pipe connected to the drug outlet, and a branch pipe connected to 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 fuselage regardless of the amount of liquid medicine in stock, so as to avoid unstable center of gravity of the drone , at the same time, a drug outlet is set at the lowermost end of the storage bin 3, which is beneficial to the output of liquid medicine, and a spherical branch device 7 is installed at the drug outlet, and the water pressure at each branch pipe of the spheric...

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 ...
