[0015] A method for using an assembled agricultural field spraying drone, S1: Pesticides to be added are injected into a structure composed of a lower water tank and an upper water tank through a discharge port, the pesticides and water injected into the lower water tank and the upper water tank contact and collide with an inclined liquid guide plate, a first liquid discharge plate, and a second liquid discharge plate, the pesticides and water are further mixed, and a driving motor drives a driving blade and an anti-foam ring to rotate, and the pesticides and water in the lower water tank and the upper water tank are further mixed;

[0016] S2: After the power supply battery is charged, install it. Adjust the position of the lifting and lowering baffle sleeve as needed. When the liquid inlet is exposed, the pesticide enters the liquid discharge pump through the liquid inlet and is discharged through the spray port. When the liquid retaining ring at the bottom of the liquid discharge pump is exposed, the pesticide enters from the gap between the liquid retaining ring and the bottom of the inner wall of the lower water tank.

[0017] S3: The upper lifting buckle drives the bottom support plate and the anti-skid pad to slide, and the bottom support plate and the anti-skid pad are supported at the bottom of the power supply battery. The second locking bolt is turned to fix the adjusted lifting buckle, and then another height adjustable frame is adjusted. The height adjustable frame at this position drives another bottom support plate and the anti-skid pad to move to support the bottom of the lower water tank.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Adjust the position of the lifting choke sleeve as needed to enable pesticides to enter the liquid discharge pump from different positions. The electric push rod drives the lifting choke sleeve to rise and fall. When the liquid inlet is exposed, the pesticide enters the liquid discharge pump through the liquid inlet. When the lifting choke sleeve is driven up by the electric push rod piston rod, the liquid retaining ring at the bottom of the liquid discharge pump is exposed, and the pesticide enters from the gap between the liquid retaining ring and the bottom of the inner wall of the lower water tank. The inclined design of the upper surface of the conical liquid retaining plate can limit the flow of pesticides, thereby preventing impurities from entering the liquid discharge pump. Impurities may cause wear on the internal components of the equipment, such as pipes, spray structures, etc. Over time, wear will reduce the performance and life of the equipment and increase maintenance costs. By preventing the discharge of impurities, the impact and friction of impurities on the equipment can be reduced, the service life of the equipment can be extended, and the maintenance cost of the equipment can be reduced.

[0020] 2. The pesticide is injected into the structure composed of the lower water tank and the upper water tank through the discharge port. The pesticide and water injected into the lower water tank and the upper water tank contact with the plug and collide with the inclined liquid guide plate, and the pesticide and water are further mixed. The second liquid discharge plate is contacted and collided, and the pesticide and water are further mixed. The driving motor drives the driving blade and the anti-foam ring to rotate to drive the pesticide and water in the lower water tank and the upper water tank to be further mixed, thereby ensuring that the pesticide is evenly mixed with the water. Good mixing can ensure that the pesticide is evenly distributed in the water, and when applied to crops, each place can get a more consistent amount of medicine.

[0021] 3. The installation stability of the structure composed of the bottom support plate and the anti-skid pad is achieved by turning the first locking bolt. The bottom support plate and the anti-skid pad are supported at the bottom of the power supply battery. Then another height-adjustable frame is adjusted. The height-adjustable frame at this position drives another bottom support plate and the anti-skid pad to move, and supports the bottom of the lower water tank to ensure the stability of the corresponding lower water tank. The water tank is a relatively heavy component on the drone. A good water tank support can firmly fix the water tank on the drone to ensure its stable position, which helps to maintain the center of gravity balance of the drone, prevent the drone from unstable flight due to shaking or displacement of the water tank, and reduce the risk of crashing.

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 14The present invention provides a technical solution: an assembled farmland pesticide spraying drone and a method of using the same, comprising an installation chassis 1 and a rectangular assembly frame 2 fixedly installed on the top of the installation chassis 1, the installation chassis 1 and the rectangular assembly frame 2 form an installed main structure, the installation chassis 1 is a frame structure to reduce the overall weight of the structure composed of the installation chassis 1 and the rectangular assembly frame 2, a structure composed of a lower water tank 3 and an upper water tank 4 is movably mounted in the rectangular assembly frame 2, and the bottom of the upper water tank 4 is in contact with the top of the rectangular assembly frame 2, ensuring that the bottom of the upper water tank 4 is in contact with the rectangular assembly frame 2. The top of the frame 2 fits, and the stability of the upper water tank 4 and the lower water tank 3 being engaged on the rectangular assembly frame 2 is maintained. A drainage port 5 is fixedly installed at the bottom of the inner wall of the lower water tank 3. The drainage port 5 is used for discharging liquid pesticides in the structure composed of the lower water tank 3 and the upper water tank 4. A drainage pump 6 located in the lower water tank 3 is arranged above the drainage port 5. The drainage pump 6 is used to extract the liquid in the lower water tank 3 and the upper water tank 4 for discharge. A protective top cover 7 is fixedly installed on the top of the drainage pump 6. An electric push rod 8 is fixedly installed on the protective top cover 7. A protective sleeve 9 is provided on the movable sleeve of the electric push rod 8. 9 protects the circuits on the electric push rod 8 and the electric push rod 8 to ensure the normal operation and work of the electric push rod 8. The outer movable sleeve of the liquid displacement pump 6 is provided with a lifting choke sleeve 10. By lifting and lowering the lifting choke sleeve 10, the opening and closing of the liquid inlet at different heights can be controlled. The piston rod of the electric push rod 8 is fixedly installed on the top of the lifting choke sleeve 10. The lifting choke sleeve 10 is driven by the piston rod of the electric push rod 8 to lift and lower to control the opening and closing of the liquid inlet at different heights. The liquid displacement pump 6 is provided with a liquid inlet 11, and the liquid inlet 11 is connected to the liquid displacement pump 6. The liquid inlet 11 is a relatively high inlet for the liquid to enter the drainage pump 6. A conical liquid blocking disc 12 and a liquid blocking ring 13 are fixedly installed at the bottom of the drainage pump 6. The conical liquid blocking disc 12 and the liquid blocking ring 13 are coaxially arranged, and the liquid blocking ring 13 is located outside the conical liquid blocking disc 12. The gap between the conical liquid blocking disc 12 and the liquid blocking ring 13 is connected to the drainage pump 6. The liquid blocking ring 13 limits the flow of pesticides. The inclined surface formed by the conical liquid blocking disc 12 can block the residue in the pesticide, preventing a large amount of residue from entering the structure composed of the conical liquid blocking disc 12 and the liquid blocking ring 13.

[0039] The lower water tank 3 and the upper water tank 4 are an integrally formed structure, and the integrally formed lower water tank 3 and the upper water tank 4 are more convenient to manufacture, and the size of the upper water tank 4 is larger than the size of the opening on the rectangular assembly frame 2, thereby ensuring the effect of the upper water tank 4 and the lower water tank 3 forming a structure that is snapped on the rectangular assembly frame 2, thereby ensuring the fixed stability of the upper water tank 4 and the lower water tank 3 forming a structure.

[0040] There is a gap of 1 to 2 cm between the liquid blocking ring 13 and the bottom of the inner wall of the lower water tank 3. The conical liquid blocking plate 12 fits the bottom of the inner wall of the lower water tank 3. After being blocked by the liquid blocking ring 13, the pesticide enters the structure composed of the conical liquid blocking plate 12 and the liquid blocking ring 13.

[0042] A driving motor 17 is fixedly installed on the top of the top mounting cover 15, and a driving rod 18 is fixedly installed on the output shaft of the driving motor 17. A plurality of driving blades 19 are fixedly installed outside the driving rod 18, and the outer edges of the plurality of driving blades 19 are connected by an anti-foam ring 20. A structure consisting of a plurality of driving blades 19 and an anti-foam ring 20 is provided on the driving rod 18. The driving motor 17 drives the driving rod 18 to rotate, thereby driving the structure consisting of the driving blades 19 and the anti-foam ring 20 to rotate, and mixes the pesticides in the structure consisting of the lower water tank 3 and the upper water tank 4 to prevent the water and the pesticides from being mixed unevenly. The anti-foam ring 20 limits the centrifugal force generated by the rotation of the driving blades 19 to prevent the driving blades 19 from generating pressure on the water flow during the rotation.

[0043] A first drainage plate 21 and a second drainage plate 22 are fixedly installed on the inner wall of the lower water tank 3. An oblique liquid guide plate 23 is arranged between the first drainage plates 21 for connection. Multiple drainage grooves are provided on the first drainage plate 21 and the second drainage plate 22. After the pesticide falls into the upper water tank 4, it collides with the structure formed by the first drainage plate 21 and the oblique liquid guide plate 23 to assist the mixing of the pesticide. The second drainage plate 22 below can further mix the pesticide.

[0044] The corresponding horizontal position of the side of the first drainage plate 21 and the second drainage plate 22 close to the inner wall of the lower water tank 3 is lower than the side of the first drainage plate 21 and the second drainage plate 22 away from the inner wall of the lower water tank 3, ensuring the smoothness of the pesticide falling downward when it contacts the inclined liquid guide plate 23 and the first drainage plate 21.

[0045] A plurality of groups of oblique mounting rods 24 are fixedly mounted on the outer surface of the rectangular assembly frame 2.

A fixing buckle 30 is provided outside the fixed sleeve composed of the structure composed of the oblique mounting rod 24, the electric wire 28 and the infusion tube 29. The servo motor 25 drives the flying paddle 26 to rotate, and the servo motor 25 is powered by the electric wire 28. The pesticide in the drainage port 5 is injected into the spray port 27 through the infusion tube 29 and discharged through the spray port 27.

[0046] A connecting plate 31 is provided on the side of the rectangular assembly frame 2, and a control assembly 32 is fixedly installed on the side of the connecting plate 31 away from the rectangular assembly frame 2. A power supply battery 33 is movably inserted into the structure formed by the connecting plate 31 and the control assembly 32. A plug 34 is fixedly installed on the power supply battery 33, and the plug 34 is movably inserted into the control assembly 32. The wire 28 and the control assembly 32 are electrically connected. The power supply battery 33 and the plug 34 form a structure that is movably inserted into the connecting plate 31 and the control assembly 32. By disassembling the power supply battery 33, the replacement of the power supply battery 33 is assisted, thereby improving the overall durability.

[0047] A vertical mounting frame 35 is fixedly installed on the mounting base 1. The vertical mounting frame 35 is a rectangular frame. A height-adjustable frame 36 is slidably connected in the vertical mounting frame 35. A bottom support plate 37 is laterally movably inserted in the height-adjustable frame 36. An anti-skid pad 38 is provided on the upper surface of the bottom support plate 37. The bottom support plate 37 and the anti-skid pad 38 form a structure supported at the bottom of the power supply battery 33 and the bottom of the lower water tank 3 to ensure the placement stability of the lower water tank 3 and the power supply battery 33. A first locking bolt 39 is threadedly connected to the height-adjustable frame 36. The first locking bolt 39 is supported at a corresponding position on the upper surface of the bottom support plate 37. A lifting bolt 38 is fixedly installed at one end of the height-adjustable frame 36. The buckle 40, the lifting buckle 40 is slidably connected with the vertical mounting frame 35, the lifting buckle 40 is a structure sleeved on the vertical mounting frame 35, and the lifting buckle 40 is composed of two rectangular frames, and the height adjustable frame 36 slides on the vertical mounting frame 35 through the lifting buckle 40, and the lifting buckle 40 is threadedly connected with a second locking bolt 41, and the second locking bolt 41 is supported at a corresponding position on the outer wall of the vertical mounting frame 35. A side drag strip 42 is fixedly installed on the bottom support plate 37 on the side of the power supply battery 33, and the structure composed of the side drag strip 42 and the bottom support plate 37 adapts to the shape of the power supply battery 33 to enhance the placement and fixing effect of the power supply battery 33.

[0048] Working principle:

[0049] The first step: the pesticide to be added is injected into the structure composed of the lower water tank 3 and the upper water tank 4 through the discharge port 16, and the pesticide and water injected into the lower water tank 3 and the upper water tank 4 contact with the inclined liquid guide plate 23 and collide with the inclined liquid guide plate 23. During the collision, the pesticide and water are further mixed, flow along the inclined first liquid discharge plate 21, and flow downward through the drainage hole on the first liquid discharge plate 21, and contact and collide with the second liquid discharge plate 22, and the pesticide and water are further mixed. The driving motor 17 drives the driving rod 18 to rotate, and the driving rod 18 rotates to drive the driving blade 19 and the anti-foam ring 20 to rotate. The driving blade 19 and the anti-foam ring 20 rotate to drive the pesticide and water in the lower water tank 3 and the upper water tank 4 to be further mixed, thereby ensuring that the pesticide and water are evenly mixed and improving the quality of the sprayed pesticide.

[0050] Step 2: After the power supply battery 33 is fully charged, the power supply battery 33 is inserted into the structure composed of the connecting plate 31 and the control assembly 32, and the plug 34 is movably inserted into the control assembly 32 to realize the assembly of the power supply battery 33 in the connecting plate 31 and the control assembly 32. The power supply battery 33 supplies power through the wire 28 to drive the servo motor 25 to work, and the servo motor 25 drives the flight propeller 26 to rotate, thereby driving the UAV to fly. During the flight, the drainage pump 6 works, and the position of the lifting choke sleeve 10 is adjusted as needed to realize the entry of pesticides into the drainage pump 6 from different positions, and the electric push rod 8 drives the lifting choke sleeve 10 down When descending, the liquid inlet 11 is exposed, the drainage pump 6 works to generate suction, the pesticide enters the drainage pump 6 through the liquid inlet 11, is discharged through the drainage port 5, enters the infusion pipe 29, and is discharged through the spray port 27. When the lifting choke sleeve 10 is driven to rise by the piston rod of the electric push rod 8, the liquid retaining ring 13 at the bottom of the drainage pump 6 is exposed, the drainage pump 6 works, and the pesticide enters from the gap between the liquid retaining ring 13 and the bottom of the inner wall of the lower water tank 3. The inclined design of the upper surface of the conical liquid retaining disk 12 can limit the flow of pesticides, thereby preventing impurities from entering the drainage pump 6 and assisting the flow of pesticides.

[0051] The third step: the upper lifting buckle 40 is slid on the vertical mounting frame 35 to drive the height adjustable frame 36 to slide on the vertical mounting frame 35. After the height adjustable frame 36 slides to the specified height on the vertical mounting frame 35, the bottom support plate 37 and the anti-skid pad 38 are installed in the height adjustable frame 36, and the installation stability of the bottom support plate 37 and the anti-skid pad 38 is achieved by screwing the first locking bolt 39. The bottom support plate 37 and the anti-skid pad 38 are supported at the bottom of the power supply battery 33. At the same time, a side drag strip 42 is provided on one side of the bottom support plate 37 and the anti-skid pad 38 at this position to better support the power supply battery 33. The second locking bolt 41 is screwed to fix the adjusted lifting buckle 40, thereby fixing the height adjustable frame 36. Then, another height adjustable frame 36 is adjusted. The height adjustable frame 36 at this position drives another bottom support plate 37 and the anti-skid pad 38 to move, so as to support the bottom of the lower water tank 3 and ensure the stability of the corresponding lower water tank 3.
