Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle equipment, in particular to an unmanned aerial vehicle for spraying pesticides. Background Technique

[0002] Summer is coming, and the crops in the fields are already green. When applying liquid fertilizer and spraying pesticides to the crops, generally, farmers carry a manual sprayer on their backs. Since the sprayer filled with pesticides is very heavy, the work of spraying pesticides becomes very laborious, and there is also a risk of pesticide poisoning. In recent years, with the development of civilian unmanned aerial vehicles, pesticide spraying unmanned aerial vehicles have also begun to "fly" into ordinary people's homes.

[0003] For example, the patent with the national authorized patent publication number CN219884082U discloses a pesticide spraying unmanned aerial vehicle, including a main body box. A driving motor is fixedly installed in the middle of the top of the main body box. The driving motor is fixedly installed with a movable rod through a rotating shaft at the output end. First mounting plates are fixedly installed on the left and right sides of the bottom of the main body box, and a medicine storage barrel is fixedly installed at the bottom of the first mounting plate. Through the driving motor, the driving gear, the driven gear, the movable rod, the rotating rod and the connecting rod, the stirring blades, the first fan blade and the second fan blade can be driven to rotate at the same time. Since the diameter of the driving gear is larger than that of the driven gear, the rotation speeds of the first fan blade and the second fan blade will be faster than that of the stirring blades. Therefore, the driving motor can simultaneously achieve the purpose of providing flight power for the device and stirring the liquid medicine. Stirring the liquid medicine can prevent the components of the liquid medicine from precipitating in the medicine storage barrel, so that the components of the sprayed liquid medicine are more uniform.

[0004] However, the above-mentioned pesticide spraying unmanned aerial vehicle does not have the function of hovering and automatically sucking and storing pesticides after the pesticides are sprayed, and it is difficult to achieve the purpose of non-contact filling of pesticides. Instead, it requires the staff to operate the unmanned aerial vehicle to fly back to add pesticides again. Each time pesticides are added, the spraying needs to be paused, which will lead to discontinuity of pesticide spraying and affect the coverage effect and prevention effect of pesticides. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pesticide spraying unmanned aerial vehicle to solve the problem that after the pesticides are sprayed, it does not have the function of hovering and automatically sucking and storing pesticides, and it is difficult to achieve the purpose of non-contact filling of pesticides. Instead, it requires the staff to operate the unmanned aerial vehicle to fly back to add pesticides again. Each time pesticides are added, the spraying needs to be paused, which will lead to discontinuity of pesticide spraying.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pesticide spraying drone, comprising: a drone body, a ring frame is fixedly installed between the propeller arms of the drone body, a pesticide spraying mechanism is fixedly installed on the outer surface of the ring frame, a sleeve frame is fixedly installed on the lower surface of the drone body, a storage tank is sleeved inside the sleeve frame, the pesticide spraying mechanism is communicated with the storage tank, and a pesticide filling mechanism is rotatably installed on the lower surface of the storage tank.

[0008] Preferably, the pesticide spraying mechanism includes a water pump, the water pump is detachably installed on both sides of the storage tank, the water intake of the water pump is communicated and installed with the storage tank, the water outlet of the water pump is connected to a pressure column through a water pipe, and the pressure column is fixedly installed on the outer surface of the ring frame.

[0009] Preferably, an atomizing nozzle is communicated and installed on the lower surface of the pressure column.

[0011] Preferably, a micro self-priming pump is communicated and installed in the middle section of the hose, and the micro self-priming pump is fixedly installed inside the second connecting arm.

[0012] Preferably, one end of the second connecting arm is rotatably connected to the piston rod of an electric push rod, and the electric push rod is rotatably installed on the lower surface of the storage tank.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Through the design of the drone body, the pesticide spraying mechanism, the pesticide filling mechanism, the sleeve frame and the storage tank, when spraying pesticides, the drone body can be controlled to fly above the field and then the pesticide spraying mechanism is started to extract the pesticides in the storage tank and atomize and spray them on the crops. After the pesticides in the storage tank are sprayed out, the staff can operate the drone body to fly to the nearest pesticide filling area and hover. Subsequently, the pesticide filling mechanism can be started to unfold and insert into the pesticide filling pool or barrel to realize the extraction and filling of pesticides, achieving contactless pesticide filling, and also eliminating the need for the drone to fly back, thereby shortening the filling time, improving the spraying efficiency, reducing the frequency and complexity of manual operations at the same time. The staff only needs to operate the pesticide filling mechanism in the filling area, reducing the labor intensity and labor cost, and enabling the drone body to quickly resume spraying operations, reducing interruptions during spraying, ensuring uniform coverage of pesticides, and improving the control effect.

[0015] 2. Through the design of a water pump, a pressure column, an atomizing nozzle, a second connecting arm, a hose, an electric push rod, and a micro self-priming pump, when spraying pesticides, the pesticides in the storage tank can be pumped out by starting the water pump and fed into the pressure column. The pressure column can then pressurize the pesticides and atomize and spray them on the crops from the atomizing nozzle at the lower end. After spraying all the pesticides in the storage tank, the operator can fly the UAV body to the nearest pesticide refilling area and hover. Subsequently, the electric push rod can be started to push and extend the second connecting arm to rotate within the first connecting arm through the piston rod. The second connecting arm can then drive the hose sleeved with the collar inside to rotate. The rotation stops until the second connecting arm drives the hose to be extended into a vertical shape. The extended second connecting arm will also drive the hose to be inserted into the pesticide refilling pool or barrel. Subsequently, the micro self-priming pump can be started to pump the pesticides through the hose and refill them into the storage tank. After the pumping is completed, the UAV body can quickly resume the spraying operation, reducing the interruption during spraying, ensuring uniform coverage of the pesticides, improving the control effect, and also realizing contactless pesticide refilling. This contactless refilling reduces the direct contact between the operator and the pesticides, reducing the risk of exposure to pesticides. Moreover, under adverse weather conditions, hovering for refilling is safer and more reliable than frequent takeoffs and landings. Description of the Drawings

[0025] Through the design of the drone body 1, the pesticide spraying mechanism 3, the pesticide filling mechanism 2, the sleeve frame 103 and the storage tank 101, when spraying pesticides, the drone body 1 can be controlled to fly above the field and then the pesticide spraying mechanism 3 is started to extract the pesticides in the storage tank 101 and atomize and spray them on the crops. Until the pesticides in the storage tank 101 are sprayed out, the staff can operate the drone body 1 to fly to the nearest pesticide filling area and hover. Subsequently, the pesticide filling mechanism 2 can be started to push and insert into the pesticide filling pool or barrel to achieve the extraction and filling of pesticides, realizing contactless pesticide filling, and also eliminating the need for the drone to fly back, thereby shortening the filling time, improving the spraying efficiency, and at the same time reducing the frequency and complexity of manual operations. The staff only needs to operate the pesticide filling mechanism 2 in the filling area, reducing the labor intensity and labor cost, and enabling the drone body 1 to quickly resume spraying operations, reducing interruptions during spraying, ensuring uniform coverage of pesticides, and improving the control effect.

[0026] As Figures 4 - 5 shown, the pesticide spraying mechanism 3 includes a water pump 303, the water pump 303 is detachably installed on both sides of the storage tank 101, the water intake of the water pump 303 is communicated with the storage tank 101, and the water outlet of the water pump 303 is connected to a pressure column 301 through a water pipe. The pressure column 301 is fixedly installed on the outer surface of the ring frame 102.

[0027] A spray nozzle 302 is connected and installed on the lower surface of the pressure column 301.

[0028] The pesticide adding mechanism 2 includes a first connecting arm 202, which is fixedly installed on the lower surface of the storage tank 101. A second connecting arm 203 is rotatably installed inside the first connecting arm 202. A collar 206 is fixedly installed inside the second connecting arm 203. A hose 204 is sleeved inside the collar 206, and the hose 204 is communicated with the storage tank 101.

[0029] A micro self-priming pump 205 is communicated and installed at the middle section of the hose 204, and the micro self-priming pump 205 is fixedly installed inside the second connecting arm 203.

[0030] One end of the second connecting arm 203 is rotatably connected to the piston rod of the electric push rod 201, and the electric push rod 201 is rotatably installed at the lower surface of the storage tank 101.

[0031] Through the design of the water pump 303, the pressurizing column 301, the atomizing nozzle 302, the second connecting arm 203, the hose 204, the electric push rod 201 and the micro self-priming pump 205, when spraying pesticides, the pesticides in the storage tank 101 can be pumped out and fed into the pressurizing column 301 by starting the water pump 303. The pressurizing column 301 can pressurize the pesticides and atomize and spray them on the crops from the atomizing nozzle 302 at the lower end. Until the pesticides in the storage tank 101 are sprayed out, the staff can operate the UAV body 1 to fly to the nearest pesticide adding area and hover. Subsequently, the electric push rod 201 can be started to push and extend the second connecting arm 203 to rotate inside the first connecting arm 202, and the second connecting arm 203 can drive the hose 204 sleeved by the collar 206 inside to rotate until the second connecting arm 203 drives the hose 204 to be pushed and extended into a vertical shape and then stop.

Subsequently, the micro self-priming pump 205 can be started to pump and add the pesticides into the storage tank 101 through the hose 204. After the extraction is completed, the UAV body 1 can quickly resume the spraying operation, reduce the interruption during the spraying process, ensure uniform coverage of the pesticides, improve the control effect, and also realize contactless pesticide addition. This contactless addition reduces the direct contact between the staff and the pesticides, reduces the risk of exposure to the pesticides, and in bad weather conditions, hovering for adding medicine is safer and more reliable than frequent takeoffs and landings.

[0032] Summarize and sort out the working steps of this solution according to the above technical solution: When spraying pesticides, the UAV body 1 can be controlled to fly above the field, and then the water pump 303 is started to extract the pesticides in the storage tank 101 and supply them into the pressure column 301. The pressure column 301 can then pressurize the pesticides and atomize and spray them on the crops from the atomizing nozzle 302 at the lower end. Until the pesticides in the storage tank 101 are sprayed out, the staff can operate the UAV body 1 to fly to the nearest pesticide refilling area and hover. Subsequently, the electric push rod 201 can be started to push the second connecting arm 203 to rotate within the first connecting arm 202 through the piston rod. The second connecting arm 203 can drive the hose 204 sleeved with the collar 206 inside to rotate. Stop until the second connecting arm 203 drives the hose 204 to be extended into a vertical shape. The extended second connecting arm 203 will also drive the hose 204 to insert into the pesticide refilling pool or barrel. Subsequently, the micro self-priming pump 205 can be started to extract the pesticides through the hose 204 and refill them into the storage tank 101. After the extraction is completed, the UAV body 1 can quickly resume the spraying operation.

[0033] In summary: This pesticide spraying UAV realizes contactless pesticide refilling, eliminates the need for the UAV to fly back, thereby shortening the refilling time, improving the spraying efficiency, reducing the frequency and complexity of manual operations at the same time. The staff only need to operate the pesticide refilling mechanism 2 in the refilling area, reducing the labor intensity and labor costs, and enabling the UAV body 1 to quickly resume the spraying operation, reducing interruptions during spraying, ensuring uniform coverage of pesticides, and improving the control effect.
