[0002] China is a large agricultural country, with about 1.8 billion mu of farmland requiring agricultural plant protection every year. The traditional method of manual spraying of pesticides not only brings physical harm to farmers, but also causes agricultural poisoning. In addition, manual spraying of pesticides can easily cause uneven coverage of pesticides, as well as pesticide residues and pollution. In recent years, with the development of drone technology, it has been widely used in the field of agricultural plant protection, which not only greatly improves the spraying efficiency, but also reduces the harm of pesticides to the human body.

[0003] When the pesticide spraying drone has finished spraying the liquid in the medicine box, it needs to return to the landing point and then be manually added. The existing device for adding medicine to the drone usually directly injects the liquid into the drone medicine box, and does not limit the drone body. Therefore, if the drone shakes during the process of adding medicine, the liquid will flow out of the medicine box and fall onto the drone, wasting the liquid and even causing damage to the drone. Therefore, it is necessary to limit the drone when adding medicine.

[0004] Therefore, an automatic dosing device for crop protection UAV is specially proposed. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] An automatic dosing device for a crop protection drone, comprising a carrying plate 1, a vertical plate 11 is fixedly installed on the top of the carrying plate 1, a horizontal plate 12 is fixedly installed on the top of the vertical plate 11, a medicine tank 13 is fixedly installed on the top of the carrying plate 1 located on the left side of the vertical plate 11, a water tank cover 14 is movably installed on the top of the medicine tank 13, a drone limiting component 4 is arranged on the top of the carrying plate 1 located on the right side of the vertical plate 11, and the drone limiting component 4 comprises a base 41, the base 41 is fixedly installed on the top right position of the carrying plate 1, a centralizing component 42 is movably installed inside the base 41, and a stop plate 43 is movably installed on the top of the centralizing component 42;

[0028] A water pump 15 is fixedly installed on the top of the horizontal plate 12, a water pump 16 is fixedly installed on the left side of the water pump 15, and the water pump 16 extends to the inside of the medicine tank 13, a supply pipe 17 is fixedly installed on the right side of the water pump 15, the supply pipe 17 passes through the horizontal plate 12 and extends below the horizontal plate 12, a telescopic bellows 171 is arranged in the middle of the supply pipe 17, a water pipe limiting frame 18 is fixedly installed on the right side of the vertical plate 11, and the water pipe limiting frame 18 is sleeved on the supply pipe 17. At the bottom of the feeding tube 17, a telescopic rod 411 is fixedly installed inside the base 41, and four groups of top grooves 412 are opened in a circular array on the top of the base 41. The end of the moving plate 421 facing the inside of the base 41 is arc-shaped. After the moving plate 421 is lowered, the moving plate 421 lifts the retracting arm 424, and the retracting arm 424 can move upward along the retracting groove 431. When the stop plate 43 is lowered to the deepest, the four groups of retracting arms 424 can be in an upright state.

[0029] By adopting the above technical solution, when in use, first open the water tank cover 14, inject medicine into the medicine tank 13, and then close the water tank cover 14. When adding medicine to the plant protection drone, the plant protection drone rests on the surface of the parking plate 43. When the plant protection drone lands on the parking plate 43, the weight of the plant protection drone causes the parking plate 43 to move downward. While the parking plate 43 moves downward, the moving plate 421 moves downward through the support column 432. When the moving plate 421 moves downward, the spring 428 and the telescopic rod 411 at the bottom are compressed. At the same time, as the moving plate 421 moves downward, the retracting arm 424 supports the top groove 412 opened on the top of the base 41. As the moving plate 421 descends deeper, the retracting arm 424 stands up higher. The gathering arm 424 moves along the support column 432. At this time, the plant protection drone is located at the top of the parking plate 43. The gathering arm 424 stands up along the gathering groove 431 and surrounds the plant protection drone. As the moving plate 421 descends, the gathering arm 424 finally fits with the plant protection drone to limit the plant protection drone to the top of the parking plate 43. When the gathering arm 424 is limiting the plant protection drone, the gathering arm 424 eventually moves toward the center of the parking plate 43. Therefore, when limiting the plant protection drone, the gathering arm 424 can center the plant protection drone at the center of the top of the sub-parking plate 43. After the plant protection drone is centered, the supply pipe 17 is directly above it. Therefore, after the plant protection drone is limited, it is also convenient to perform drug addition operations on the plant protection drone.

[0030] After the plant protection UAV is limited, a telescopic bellows 171 is provided in the middle of the supply pipe 17, so that the supply pipe 17 can be directly pulled downward to connect the supply pipe 17 to the medicine box of the plant protection UAV, and then the water pump 15 is started. The water pump 15 extracts the medicine in the medicine box 13 through the suction pipe 16 and then injects it into the medicine box of the plant protection UAV through the supply pipe 17. After the addition of medicine is completed, the plant protection UAV is removed from the top of the parking plate 43, and the parking plate 43 no longer presses the moving plate 421. The moving plate 421 is reset by the spring 428, and the restriction on the folding arm 424 is released at the same time, and the folding arm 424 is automatically reset by the counterweight block 427.

[0031] Specifically, Figures 1 to 3As shown, the central part 42 includes a moving plate 421, and the moving plate 421 is movably mounted inside the base 41. Four groups of rotation grooves 422 are provided in a circular array at the edge of the moving plate 421. Limiting grooves 423 are provided on the inner walls of the left and right sides of the rotation grooves 422. A folding arm 424 is movably installed inside the rotation groove 422. A movable rod 425 is fixedly installed on both sides of the left and right sides of the end of the folding arm 424 close to the moving plate 421. A rubber pad 426 is fixedly installed on the upper surface of the folding arm 424. A counterweight block 427 is fixedly installed on the bottom of the end of the folding arm 424 away from the moving plate 421. The moving plate 421 A spring 428 is fixedly installed at the bottom, four groups of folding grooves 431 are opened on the surface of the shutdown plate 43, and a support column 432 is fixedly installed at the bottom of the shutdown plate 43. After the shutdown plate 43, the concentrator 42 and the base 41 are installed, the folding arm 424 is stuck in the top groove 412, the folding groove 431 is located above the folding arm 424, and the support column 432 is located above the moving plate 421. The spring 428 at the bottom of the moving plate 421 is covered on the telescopic rod 411 and abuts against the inside of the base 41. A group of universal wheels 2 are fixedly installed at the four corners of the bottom of the supporting plate 1, and a handle 3 is fixedly installed on the left side of the medicine tank 13.

[0032] By adopting the above technical solution, the current penetration rate of plant protection drones is relatively high, resulting in the size of most plant protection drone operation plots being between 3 and 8 acres, resulting in a too high take-off and landing frequency of plant protection drones. Plant protection drones are generally large in size and heavy, and are not easy to move. The present device is equipped with a universal wheel 2 at the bottom of the carrier plate 1, and a handle 3 is installed on the left side of the medicine tank 13. The arrangement of the universal wheel 2 and the handle 3 facilitates the movement of the present device. When transferring the plant protection drone, the present device can be used to facilitate the transfer of the plant protection drone. At the same time, through the design of the drone limiting component 4, the plant protection drone can be limited when transferring the plant protection drone to prevent the plant protection drone from being moved due to bumps and other problems when transferring the plant protection drone. When the plant protection UAV falls, the plant protection UAV is placed on the parking plate 43. The parking plate 43 drives the moving plate 421 to descend through the support column 432 due to the weight of the plant protection UAV. When the moving plate 421 descends, the retracting arms 424 around it naturally tilt upward due to the top groove 412. The tilting height of the retracting arms 424 is proportional to the depth of the descent of the moving plate 421. The deeper the moving plate 421 descends, the higher the tilting height of the retracting arms 424. When the moving plate 421 descends to the bottom, the retracting arms 424 are in an upright state. Therefore, the plant protection UAV is placed on the parking plate 43 and the retracting arms 424 can automatically limit the plant protection UAV. This design can achieve the limitation of the plant protection UAV and prevent the plant protection UAV from falling during the transfer process.

[0033] Working principle: When in use, first open the water tank cover 14 to fill the medicine tank 13 with medicine, then close the water tank cover 14. When adding medicine to the plant protection drone, the plant protection drone is parked on the parking plate 43. Due to the weight of the plant protection drone, the parking plate 43 drops. When the parking plate 43 drops, it drives the moving plate 421 to drop through the support column 432. When the moving plate 421 drops, the retracting arm 424 is tilted up through the top groove 412. The height of the retracting arm 424 is proportional to the height of the moving plate 421. 24 automatically stands up to limit the plant protection UAV. After the plant protection UAV is limited, the supply pipe 17 is first connected to the medicine box of the plant protection UAV, and then the water pump 15 is started. The water pump 15 draws the medicine in the medicine box 13 through the suction pipe 16 and injects it into the medicine box of the plant protection UAV through the supply pipe 17. After the medicine addition is completed, the plant protection UAV is removed from the stop plate 43. The stop plate 43 no longer bears the weight of the plant protection UAV, and the spring 428 releases the pressure, thereby resetting the moving plate 421 and the stop plate 43. At the same time, the retracting arm 424 is no longer restricted because the counterweight block 427 falls naturally.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
