A pesticide spraying device for agricultural plant protection unmanned aerial vehicle

Abstract

This utility model discloses a pesticide spraying device for agricultural plant protection drones, relating to the field of pesticide spraying technology. The utility model includes a drone. By activating a stirring assembly, the pesticide-water mixture within the storage assembly is alternately stirred in both directions, thereby changing the direction of pesticide particle flow within the storage assembly. This disrupts the eddies generated during unidirectional rotation and increases the stirring area, thus improving the mixing efficiency between the pesticide and water. Since the inlet of the water pump assembly is connected to the outlet of the storage assembly, activating the inlet of the water pump assembly draws pesticide from the top-mounted storage assembly and discharges it from the outlet of the water pump assembly into the spraying assembly. The spraying assembly then atomizes and sprays the pesticide, avoiding differences in pesticide concentration before and after spraying by the drone.

Description

Technical Field

[0001] This utility model belongs to the field of pesticide spraying technology, and specifically relates to a pesticide spraying device for agricultural plant protection drones. Background Technology

[0002] Agricultural production refers to the production activities of planting crops. In the process of agricultural production, it is necessary to spray pesticides on crops. For large-scale growers, the efficiency of using drones for pesticide spraying is much higher than that of manual spraying, and it also greatly reduces labor intensity.

[0003] In the prior art, a search of Chinese patent number CN220694246U discloses a pesticide spraying device; it includes a drone body, the surface of which is provided with a fixing ring, and the bottom of the fixing ring is connected to a placement frame; two water tanks, both of which are installed at the bottom of the inner wall of the placement frame; a connecting pipe, which is disposed between the two water tanks, and the interior of the connecting pipe is provided with a movable component, and a lifting device is disposed between the two water tanks; and a spraying device, which is disposed at the bottom of the placement frame.

[0004] In existing technologies, a stirring device is typically used to agitate pesticides within the spraying device. Since this device generally mixes pesticides in one direction, the liquid forms a fixed vortex pattern within the container during unidirectional agitation. This results in lower flow velocities at the bottom, edges, or central axis of the container, making it easier for particles to deposit in these areas. The deposited pesticide gradually mixes with the water, leading to varying pesticide concentrations in different areas and consequently, differences in pesticide concentration before and after spraying. The aforementioned solution uses two water tanks and a hydraulic telescopic rod to control the raising and lowering of the connecting head, allowing pesticides to circulate between the two tanks through a connecting pipe, thus increasing pesticide storage capacity. However, during pesticide spraying, because pesticides are usually a mixture of various chemical substances and contain solid particles that easily settle, these solid particles gradually mix with the water at the bottom of the tank, resulting in different pesticide concentrations at the bottom and top of the tank, further contributing to the difference in pesticide concentration before and after spraying. Utility Model Content

[0005] In response to the problem that pesticides are usually composed of a mixture of various chemical substances and contain solid particles that easily settle, causing the solid particles to gradually mix with the water at the bottom of the tank, resulting in different pesticide concentrations at the bottom and top of the tank, and thus causing concentration differences before and after pesticide spraying, this utility model proposes a pesticide spraying device for agricultural plant protection drones to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pesticide spraying device for agricultural plant protection drones, comprising a drone:

[0008] The drone is equipped with a storage component, a stirring component, a water pump component, and a spraying component.

[0009] The storage component has its outer surface fixedly connected to the outer surface of the drone, so that the drone can move the storage component.

[0010] A stirring component is fixedly installed on one side of a storage component so that the stirring component can stir the pesticide in the storage component;

[0011] A water pump assembly, the top of which is fixedly installed to the bottom of a storage assembly, so that the water pump assembly can extract pesticides from the storage assembly;

[0012] The spraying assembly is fixedly installed at its top end to the bottom end of the water pump assembly, so that the spraying assembly can atomize and spray the pesticides drawn out by the water pump assembly.

[0013] Furthermore, the storage component includes a mounting plate, the outer surface of which is fixedly connected to the outer surface of the drone, and a medicine box is fixedly mounted on the top of the mounting plate, with a lid threaded onto the outer surface of the medicine box.

[0014] Furthermore, the stirring assembly includes a first motor, one side of which is fixedly installed with one side of the medicine tank, a first stirring column is fixedly installed at the output end of the first motor, and a transmission gear is fixedly installed on the outer surface of the first stirring column.

[0015] Furthermore, the stirring assembly also includes a first gear and a second gear. The surface of the first gear meshes with one side of the transmission gear. A second stirring column is fixedly installed on the inner wall of the first gear. The surface of the second gear meshes with the surface of the transmission gear. A third stirring column is installed on the inner wall of the second gear.

[0016] Furthermore, the water pump assembly includes a mounting bracket, the top of which is fixedly mounted to the bottom of a mounting plate. A gear pump is fixedly mounted on one side of the mounting bracket, the top of which is fixedly mounted to the bottom of a medicine tank. A second motor is fixedly mounted on the other side of the mounting bracket, and the output end of the second motor is fixedly mounted to one end of the gear pump.

[0017] Furthermore, the spraying assembly includes a delivery pipe, the top end of which is fixedly installed to the bottom end of the gear pump, and an atomizing nozzle is fixedly installed at the bottom end of the delivery pipe.

[0018] Furthermore, the spraying assembly also includes a bracket, the top of which is fixedly installed to the bottom of the mounting plate, and the inner wall of the bracket is fixedly installed to the outer surface of the delivery pipe.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model uses the stirring component 3 to alternately stir the drug-water mixture in the storage component 2, thereby changing the direction of drug particle flow in the storage component 2. This can disrupt the eddies generated during unidirectional rotation and increase the stirring area, thereby improving the mixing efficiency between the drug and water. Since the inlet of the water pump component 4 is connected to the outlet of the storage component 2, the drug in the storage component 2 installed at the top is extracted by activating the inlet of the water pump component 4 and discharged from the outlet of the water pump component 4 into the spraying component 5. Then, the spraying component 5 atomizes and sprays the drug inside, avoiding the difference in pesticide concentration before and after the drone spraying process.

[0021] 2. This utility model drives the first stirring column installed at the output end of the first motor to rotate, so that the first stirring column stirs the medicine-water mixture inside the medicine tank. At the same time, when the first stirring column rotates, it can drive the transmission gear installed on its outer surface to rotate. Since the surface of the transmission gear meshes with the surface of the first gear and the second gear respectively, and the first gear and the second gear are respectively installed with the second stirring column and the third stirring column, when the transmission gear rotates, it can cooperate with the first gear and the second gear to drive the second stirring column and the third stirring column to stir the medicine-water mixture inside the medicine tank. The rotation direction of the second stirring column and the third stirring column is opposite to the rotation direction of the first stirring column, so as to increase the stirring area and avoid the generation of eddies during the stirring process, thereby accelerating the mixing efficiency between the drug particles and water.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0034] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0035] Please see Figures 1-7 As shown, this utility model is a pesticide spraying device for agricultural plant protection drones, including drone 1:

[0036] The drone 1 is equipped with a storage component 2, a stirring component 3, a water pump component 4, and a spraying component 5.

[0037] Storage component 2, the outer surface of which is fixedly connected to the outer surface of drone 1, so that drone 1 can move storage component 2;

[0038] The stirring component 3 is fixedly installed on one side of the storage component 2 so that the stirring component 3 can stir the pesticide in the storage component 2;

[0039] The top of the water pump assembly 4 is fixedly installed to the bottom of the storage assembly 2 so that the water pump assembly 4 can extract the pesticide from the storage assembly 2.

[0040] The spraying component 5 is fixedly installed at its top end to the bottom end of the water pump component 4 so that the spraying component 5 can atomize and spray the pesticides extracted by the water pump component 4.

[0041] During use, the stirring component 3 is activated to alternately stir the pesticide mixture in the storage component 2, thereby changing the direction of the pesticide particle flow in the storage component 2. This can disrupt the eddies generated during unidirectional rotation and increase the stirring area, thus improving the mixing efficiency between the pesticide and water. Since the inlet of the water pump component 4 is connected to the outlet of the storage component 2, the pesticide in the top-mounted storage component 2 is extracted by activating the inlet of the water pump component 4 and discharged from the outlet of the water pump component 4 into the spraying component 5. Then, the spraying component 5 atomizes and sprays the pesticide inside, avoiding the difference in pesticide concentration before and after the drone spraying process.

[0042] This invention uses the stirring assembly 3 to alternately stir the pesticide mixture in the storage assembly 2, thereby changing the direction of the pesticide particle flow in the storage assembly 2. This disrupts the eddies generated during unidirectional rotation and increases the stirring area, thus improving the mixing efficiency between the pesticide and water. Since the inlet of the water pump assembly 4 is connected to the outlet of the storage assembly 2, the pesticide in the top-mounted storage assembly 2 is extracted by activating the inlet of the water pump assembly 4 and discharged from the outlet of the water pump assembly 4 into the spraying assembly 5. Then, the spraying assembly 5 atomizes and sprays the pesticide inside, avoiding the concentration difference of pesticide before and after the drone spraying process.

[0043] In one embodiment, the storage component 2 includes a mounting plate 201, the outer surface of which is fixedly connected to the outer surface of the drone 1, and a medicine box 202 is fixedly mounted on the top of the mounting plate 201. A box cover 203 is threaded onto the outer surface of the medicine box 202.

[0044] Because the bottom of the medicine box 202 is fixed to the top of the mounting plate 201, and the outer surface of the mounting plate 201 is fixed to the outer surface of the drone 1, when the drone 1 is in flight, it can move the medicine box 202 in conjunction with the mounting plate 201. By rotating the box cover 203, it can be removed from one end of the medicine box 202, and pesticides can be added into the medicine box 202.

[0045] In one embodiment, the stirring assembly 3 includes a first motor 301, one side of the first motor 301 is fixedly installed on one side of the medicine tank 202, a first stirring column 302 is fixedly installed at the output end of the first motor 301, and a transmission gear 303 is fixedly installed on the outer surface of the first stirring column 302.

[0046] The stirring assembly 3 also includes a first gear 304 and a second gear 306. The surface of the first gear 304 meshes with the surface of the transmission gear. A second stirring column 305 is fixedly installed on the inner wall of the first gear 304. The surface of the second gear 306 meshes with the surface of the transmission gear 303. A third stirring column 307 is fixedly installed on the inner wall of the second gear 306.

[0047] The first motor 301 drives the first stirring column 302 installed at its output end to rotate, thereby stirring the medicine mixture inside the medicine tank 202. Simultaneously, the rotation of the first stirring column 302 drives the transmission gear 303 installed on its outer surface to rotate. Since the surface of the transmission gear 303 meshes with the surfaces of the first gear 304 and the second gear 306 respectively, and the first gear 304 and the second gear 306 respectively house the second stirring column 305 and the third stirring column 307, the rotation of the transmission gear 303, in conjunction with the first gear 304 and the second gear 306, drives the second stirring column 305 and the third stirring column 307 to stir the medicine mixture inside the medicine tank 202. Furthermore, the rotation direction of the second stirring column 305 and the third stirring column 307 is opposite to the rotation direction of the first stirring column 302, which increases the stirring area and avoids the generation of eddies during stirring, thereby accelerating the mixing efficiency between the drug particles and water.

[0048] In one embodiment, the water pump assembly 4 includes a mounting bracket 401. The top of the mounting bracket 401 is fixedly mounted to the bottom of the mounting plate 201. A gear pump 402 is fixedly mounted to the top of the mounting bracket 401. The top of the gear pump 402 is fixedly mounted to the bottom of the medicine tank 202. A second motor 403 is fixedly mounted to the other side of the mounting bracket 401. The output end of the second motor 403 is fixedly mounted to one end of the gear pump 402.

[0049] By starting the second motor 403, the gear pump 402 installed at the output end is driven to operate. Since the water inlet of the gear pump 402 is connected to the inside of the medicine tank 202, when the gear pump 402 is running, it can draw out the medicine inside the medicine tank 202 and spray the medicine out from the water outlet. The mounting bracket 401 can support the gear pump 402 and the second motor 403 installed on both sides respectively, so as to improve the stability of the second motor 403 and the gear pump 402 during operation.

[0050] In one embodiment, the spraying assembly 5 includes a delivery pipe 501, the top end of which is fixedly installed with the bottom end of the gear pump 402, and an atomizing nozzle 502 is fixedly installed at the bottom end of the delivery pipe 501.

[0051] The spraying assembly 5 also includes a bracket 503, the top of which is fixedly installed to the bottom of the mounting plate 201, and the inner wall of the bracket 503 is fixedly installed to the outer surface of the delivery pipe 501.

[0052] Since the outlet of the gear pump 402 is connected to the inside of the delivery pipe 501, when the medicine is sprayed from the outlet of the gear pump 402, the medicine can enter the inside of the delivery pipe 501 and be sprayed from one end of the atomizing nozzle 502 installed at the bottom of the delivery pipe 501. Thus, the atomizing nozzle 502 can atomize and spray the medicine. Since there are multiple sets of atomizing nozzles 502 arranged symmetrically, the atomizing nozzle 502 can increase the spraying area of ​​the medicine when atomizing and spraying it.

[0053] In summary, by utilizing the above-described technical solution of this utility model, the first stirring column 302 installed at the output end of the first motor 301 is started to rotate, so that the first stirring column 302 stirs the medicine mixture inside the medicine tank 202. Simultaneously, when the first stirring column 302 rotates, it drives the transmission gear 303 installed on its outer surface to rotate. Since the surface of the transmission gear 303 meshes with the surfaces of the first gear 304 and the second gear 306 respectively, and the first gear 304 and the second gear 306 respectively have a second stirring column 305 and a third stirring column 307 installed inside, when the transmission gear 303 rotates, it can cooperate with the first gear 304 and the second gear 306 to drive the second stirring column 305 and the third stirring column 307 to stir the medicine mixture inside the medicine tank 202. The rotation direction of the stirring column 307 is opposite to that of the first stirring column 302, so as to increase the stirring area and avoid the generation of eddies during the stirring process, thereby accelerating the mixing efficiency between the drug particles and water. By starting the second motor 403, the gear pump 402 installed at the output end is driven to operate. Since the water inlet of the gear pump 402 is connected to the inside of the medicine tank 202, when the gear pump 402 is running, it can draw out the drug inside the medicine tank 202 and spray the drug from the water outlet. Since the water outlet of the gear pump 402 is connected to the inside of the delivery pipe 501, when the drug is sprayed from the water outlet of the gear pump 402, the drug can enter the inside of the delivery pipe 501 and be sprayed from one end of the atomizing nozzle 502 installed at the bottom of the delivery pipe 501, thereby enabling the atomizing nozzle 502 to atomize and spray the drug.

[0054] Through the above technical solution, 1. By starting the stirring component 3, the mixture of medicine and water in the storage component 2 is stirred alternately in both directions, thereby changing the direction of the flow of medicine particles in the storage component 2, thereby breaking the eddy current generated during unidirectional rotation, and increasing the stirring area, thereby improving the mixing efficiency between medicine and water. Since the inlet of the water pump component 4 is connected to the outlet of the storage component 2, by starting the inlet of the water pump component 4, the medicine in the storage component 2 installed at the top is extracted, and the medicine is discharged from the outlet of the water pump component 4 into the spraying component 5. Then the spraying component 5 atomizes and sprays the medicine inside, avoiding the difference in pesticide concentration before and after the spraying process of the drone 1.

[0055] 2. The first stirring column 302 installed at the output end of the first motor 301 is started to rotate, so that the first stirring column 302 stirs the medicine-water mixture inside the medicine tank 202. At the same time, when the first stirring column 302 rotates, it can drive the transmission gear 303 installed on its outer surface to rotate. Since the surface of the transmission gear 303 meshes with the surfaces of the first gear 304 and the second gear 306 respectively, and the second stirring column 305 and the third stirring column 307 are respectively installed inside the first gear 304 and the second gear 306, when the transmission gear 303 rotates, it can cooperate with the first gear 304 and the second gear 306 to drive the second stirring column 305 and the third stirring column 307 to stir the medicine-water mixture inside the medicine tank 202. The rotation direction of the second stirring column 305 and the third stirring column 307 is opposite to the rotation direction of the first stirring column 302, so as to increase the stirring area and avoid the generation of eddies during the stirring process, thereby accelerating the mixing efficiency between the drug particles and water.
