Description

Technical Field

[0001] The invention relates to a medicine supply device for spraying medicine by an unmanned aerial vehicle and a use method thereof, belonging to the field of agricultural machinery. Background Art

[0002] With technological advancements, more and more farmers are choosing to use drones for pesticide spraying, which is not only simple to operate but also time-saving and labor-saving. However, due to the limited mounting capacity of drones, the spraying process requires multiple returns to add pesticides. The current method of adding pesticides is relatively simple, that is, using a water pump to pump the pesticide mixed in water into the drone's storage cartridge. Although this method is simple, the mixing process of powdered pesticides inevitably leads to the presence of water-insoluble particles or impurities. Adding pesticides in this way requires subsequent cleaning of the drone's storage cartridge, which is very troublesome. Although some drones have a filter installed at the entrance of the storage cartridge, when the water pump flow is high, the filter obstructs the filter, causing some liquid to splash out, resulting in waste. Therefore, this type of refill device is designed. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology and provide a drug supply device for drone spraying and a method of using the same.

[0004] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0005] A drug supply device for drone spraying, comprising an outer cylinder, a filter barrel, a separator, a threaded cylinder and a connector; a connecting plate I is fixedly connected to the top end of the inner wall of the outer cylinder; a connecting hole is provided at the top end of the connector, and the connecting hole is connected to the outer wall of the outer cylinder via a bearing; a connecting plate II is fixedly connected to the top end of the outer wall of the filter barrel, the filter barrel is arranged inside the outer cylinder, and the connecting plate II is located at the upper end of the connecting plate I; a separator is provided inside the filter barrel, and the threaded cylinder is connected to the inner bottom end of the outer cylinder via a thread.

[0006] A method for using a drug supply device for drone spraying, the method comprising the following steps:

[0007] Step 1: Insert the water pipe into the filter barrel, move the threaded barrel to the lowest point, and start the water pump connected to the water pipe;

[0008] Step 2: After the pesticide enters the filter barrel from the water pipe, it is blocked by the partition plate and passes through the filter barrel for filtration. It is then discharged into the drone's drug storage barrel through the gap between the bottom of the filter barrel and the threaded barrel, circular holes I and II;

[0009] Step 3: Move the threaded barrel to the highest point and start the water pump. After the pesticide enters the filter barrel from the water pipe, it is blocked by the partition plate and passes through the filter barrel for filtration. The threaded barrel blocks the liquid between the outer barrel and the filter barrel and allows it to pass through the filter barrel again for secondary filtration. It is then discharged from circular holes I and II into the drug storage barrel of the drone.

[0010] Compared with the prior art, the present invention has the following advantages: the present invention can not only select single or double filtration according to the solubility of the pesticide, so as to reduce the residual residue in the drone storage cartridge and reduce the time consumed for subsequent cleaning, but also the present invention will not cause the pesticide to splash, thus avoiding waste, and the present invention is also convenient for cleaning the filter barrel.

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Specific implementation method 1: Figure 1-9 As shown, this embodiment records a drug supply device for drone spraying, including an outer cylinder 1, a filter barrel 3, a separator 4, a threaded cylinder 5 and a connector 6; the top end of the inner wall of the outer cylinder 1 is fixedly connected to a connecting plate Ⅰ11; the top end of the connector 6 is provided with a connecting hole 61, and the connecting hole 61 is connected to the outer wall of the outer cylinder 1 through a bearing; the top end of the outer wall of the filter barrel 3 is fixedly connected to a connecting plate Ⅱ31, the filter barrel 3 is arranged inside the outer cylinder 1, and the connecting plate Ⅱ31 is located at the upper end of the connecting plate Ⅰ11; the interior of the filter barrel 3 is provided with a separator 4, and the threaded cylinder 5 is connected to the inner bottom end of the outer cylinder 1 through a thread.

[0022] The inner wall of the filter barrel 3 is provided with a vertical chute 32. The partitioning device 4 includes a partition plate 41. Sliders 42 are fixedly connected to both sides of the partition plate 41 and slide in engagement with the chute 32. The slides 42 have an interference fit with the chute 32. The position of the partition plate 41 can be adjusted to ensure that when it is in the middle of the filter barrel 3, secondary filtration is possible. When the partition plate 41 is at the bottom of the filter barrel 3, single filtration is possible. When the partition plate 41 is within the circular hole I 51, the filter barrel 3 can be cleaned.

[0023] A vertical chute 32 is provided on the inner wall of the filter barrel 3 ; the partition device 4 includes a partition plate 41 ; sliders 42 that slidably cooperate with the chute 32 are fixedly connected to both sides of the partition plate 41 .

[0024] A pull ring 43 is fixedly connected to the lower end of the partition plate 41 ; a sealing ring is provided on the outer circumferential surface of the partition plate 41 ; and the partition plate 41 is slidably fitted in the circular hole I 51 of the threaded barrel 5 .

[0025] The bottom of the threaded barrel 5 is provided with a circular hole I 51 and a circular hole II 52 coaxial with the circular hole I 51 .

[0026] When the threaded barrel 5 moves to the highest point, the bottom of the filter barrel 3 is in close contact with the threaded barrel 5 .

[0027] There are two connecting plates I11 and II31, and both connecting plates I11 and II31 are arc-shaped. When connecting plates I11 and II31 overlap, it is convenient to discharge clean water and achieve the purpose of flushing the inner and outer walls of the filter barrel 3 with clean water.

[0028] The central angle of the connecting plate I11 and the connecting plate II31 is greater than 90 degrees. During filtration, the central angle of the connecting plate I11 and the connecting plate II31 greater than 90 degrees can seal the space above the filter barrel 3 and the outer cylinder 1, preventing pesticides from flowing out of the space above the filter barrel 3 and the outer cylinder 1.

[0029] The upper end of the partition plate 41 is connected to a shaft 45 via a bearing; a stirring blade 44 is fixedly connected to the shaft 45. The pesticide flowing out of the water pipe 2 drives the stirring blade 44 to rotate, providing centrifugal force for the pesticide and accelerating its passage through the filter barrel 3.

[0030] A rotating rod 46 is provided in a set of opposite filter holes on the filter screen 3, and two bevel gears I 47 are provided on the rotating rod 46; a bevel gear II 48 is provided on the shaft 45 and meshes with one of the bevel gears I 47; the lower end of the connecting plate I 11 is connected to the rotating drum 12 through a bearing; a connecting rod 13 is provided inside the rotating drum 12 and slides with the connecting rod 13, and a limiting groove 15 is provided on the inner wall of the rotating drum 12; a limiting block 14 is provided on the side of the connecting rod 13 and slides with the limiting groove 15; the outer side of the rotating drum 12 is provided with a connecting rod 13 and slides with the other bevel gear I 47 meshing bevel gear III 16; the lower end of the connecting rod 13 is fixedly connected to a gear 17; the inner wall of the threaded barrel 5 is provided with an inner barrel 56 that can rotate relative to the threaded barrel 5; the upper end of the inner wall of the inner barrel 56 is provided with an annular tooth groove 55, which meshes with the gear 17; the inner wall of the inner barrel 56 is also fixedly connected to an obliquely arranged baffle 53, the baffle 53 is in contact with the outer wall of the filter barrel 3, and a pad 54 is fixedly connected between two adjacent baffles 53; the thickness of the pad 54 increases linearly from the upper end of the threaded barrel 5 to the bottom end of the threaded barrel 5. During secondary filtration, bevel gear III 16 and bevel gear II 48 are meshed with corresponding bevel gear I 47. After the shaft 45 rotates, the inner cylinder 56 can be driven to rotate, thereby rotating the baffles 53 and the pads 54 on the inner cylinder 56. The pesticide flowing between the two adjacent baffles 53 gradually increases with the thickness of the pads 54, which speeds up the pesticide to pass through the filter barrel 3 again, speeding up the secondary filtration, avoiding affecting the flow rate and increasing the time for re-dose.

[0031] The shaft 45 and the rotating rod 46 are staggered so that the stirring blade 44 can move downward along with the partition plate 41 .

[0032] A method for using a drug supply device for drone spraying, the method comprising the following steps:

[0033] Step 1: Insert the water pipe 2 into the filter barrel 3, move the threaded barrel 5 to the lowest point, and start the water pump connected to the water pipe 2;

[0034] Step 2: After the pesticide enters the filter barrel 3 from the water pipe 2, it is blocked by the partition plate 41 and passes through the filter barrel 3 for filtration. It is then discharged into the drug storage barrel of the drone through the gap between the bottom of the filter barrel 3 and the threaded barrel 5, the circular hole I 51, and the circular hole II 52;

[0035] Step 3: After moving the threaded barrel 5 to the highest point, start the water pump. After the pesticide enters the filter barrel 3 from the water pipe 2, it is blocked by the partition plate 41 and passes through the filter barrel 3 for filtration. The threaded barrel 5 blocks the liquid between the outer barrel 1 and the filter barrel 3 and passes through the filter barrel 3 again for secondary filtration. It is then discharged into the drug storage barrel of the drone through the circular holes I 51 and II 52.

[0036] The working principle of the present invention is as follows: when using the device, the water pipe 2 is inserted into the filter barrel 3, and then the connector 6 is threadedly connected to the liquid inlet of the drug storage cartridge on the drone through the threads on the inner wall of the connector 6 to prevent the device from detaching when refilling the drug. Subsequently, the filter barrel 3 is inserted into the outer barrel 1, and the connecting plate II 31 and the outer barrel 1 have an interference fit. When refilling the drug, the connecting plates I 11 and II 31 seal the gap between the outer barrel 1 and the filter barrel 3. Finally, the threaded barrel 5 is threadedly connected to the bottom of the outer barrel 1.

[0037] When the threaded barrel 5 moves to the lowest point, the water pump connected to the water pipe 2 is started. After the pesticide enters the filter barrel 3 from the water pipe 2, it is blocked by the partition plate 41, allowing the liquid medicine to pass through the filter barrel 3 for filtration. Since there is a gap between the threaded barrel 5 and the bottom of the filter barrel 3 when the threaded barrel 5 is at the lowest point, the pesticide that passes through the filter barrel 3 will pass through the gap between the bottom of the filter barrel 3 and the threaded barrel 5, the circular hole I 51, and the circular hole II 52 and be discharged into the drug storage barrel of the drone, completing the filtration.

[0038] During the filtration process, the pesticide flowing out of the water pipe 2 impacts the stirring blade 44 and drives it to rotate, so that the pesticide rotates in the filter barrel 3, and the filtration can be accelerated under the action of centrifugal force.

[0039] When the threaded barrel 5 moves to the highest point, the water pump connected to the water pipe 2 is started. After the pesticide enters the filter barrel 3 from the water pipe 2, it is blocked by the partition plate 41, allowing the liquid medicine to pass through the filter barrel 3 for filtration. Since the threaded barrel 5 is at the highest point, the threaded barrel 5 is close to the bottom of the filter barrel 3. Therefore, the pesticide that has passed through the filter barrel 3 passes through the filter barrel 3 again, undergoes secondary filtration, and is discharged into the drug storage barrel of the drone through the circular holes I 51 and II 52.

[0040] During the secondary filtration process, due to the rotation of the stirring blade 44, the bevel gear II 48 is driven to rotate through the bevel gear I 47, and then the bevel gear III 16 is driven to rotate, so that the rotating drum 12 and the connecting rod 13 are rotated, and then the gear 17 is driven to rotate. The gear 17 drives the inner drum 56 to rotate through the annular tooth groove 55, and then drives the baffle 53 to rotate, so that the pesticide flows into the two adjacent baffles 53. Since a pad 54 with a thickness gradually increasing from top to bottom is provided between the two adjacent baffles 53, as the inner drum 56 rotates, the baffle 53 drives the pesticide to flow downward at an accelerated speed, and under the influence of the pad 54, the space between the two baffles 53 from top to bottom gradually decreases, thereby accelerating its secondary passage through the filter barrel 3, thereby avoiding the slowdown of the pesticide flow rate due to the secondary filtration.

[0041] When cleaning, pull the pull ring 43 to disengage the bevel gear II 47 from the bevel gear I 47, move the partition plate 41 into the circular hole I 51, and move the slider 42 into the circular hole II 52, then rotate the threaded barrel 5, drive the gear 17 and the connecting rod 13 downward through the tooth groove 55 until the threaded barrel 5 moves to the lowest point, leaving a gap between the filter barrel 3 and the threaded barrel 5, and then rotate the filter barrel 3 to rotate the connecting plate II 31 to coincide with the connecting plate I 11, that is, to expose the gap between the two connecting plates I 11, start the water pump, and draw clean water into the filter barrel 3 through the water pipe 2. The water flushes the inner wall of the filter barrel 3, contacts the partition plate 41 and the bottom of the threaded barrel 5, and then flows back upward, flows upward along the gap between the threaded barrel 5 and the filter barrel 3, flushes the outer wall of the filter barrel 3, and is finally discharged through the gap between the two connecting plates I 11 to complete the cleaning.
