[0001] The utility model relates to the technical field of drone pesticide spraying, in particular to a pesticide spraying device for a drone. Background Art

[0002] During the planting process of field crops, it is necessary to use drones to spray pesticides on field crops regularly. For example, the prior art CN219601602U discloses a pesticide spraying drone, which belongs to the technical field of pesticide spraying equipment. A rotating spraying part is installed on the main frame of the drone, and the rotating spraying part includes a driving part, a spraying unit and a spoiler component. The spoiler component includes two spoilers with adjustable openings. The existing spraying drones are prone to cause atomized particles to float unsteadily when facing flight vortices and natural wind, affecting the spraying uniformity.

[0003] However, the above-mentioned existing pesticide spraying drones are used to mix the pesticides first and then use the drone to drive the spraying equipment to spray field crops. This not only increases people's labor consumption, but also easily causes the precipitation of the medicine during spraying due to the lack of stirring of the mixing mechanism, thereby affecting the efficacy of the drone after spraying the pesticide.

[0028] See also Figures 1-3 The utility model provides a new technical solution: a pesticide spraying device for a drone, comprising a drone carrier 2, a pesticide spraying assembly provided on the drone carrier 2, the pesticide spraying assembly being used to spray pesticides, and a drone body assembly 1 for driving the pesticide spraying assembly to operate in the air provided on the drone carrier 2;

[0029] The pesticide spraying assembly includes a medicine barrel 3, a servo push rod 4, a blade paddle 5, a blade fixing ring 6, a fixing column 7, an inclined chute ring 9 and a water pump 11;

[0030] The medicine barrel 3 in the pesticide spraying assembly is fixedly mounted on the lower surface of the drone mounting frame 2, the servo push rod 4 is mounted in the drone body assembly 1, and the blade propeller 5 is rotatably connected to the outer surface of the output end below the servo push rod 4;

[0031] The output end of the servo push rod 4 extends into the medicine barrel 3 , and the blade fixing ring 6 is fixedly sleeved on the outer surface of the blade paddle 5 . The servo push rod 4 is used to drive the blade paddle 5 to move up and down in the medicine barrel 3 .

[0032] Furthermore, the six fixing columns 7 are all fixedly connected to the outer surface of the blade fixing ring 6, and the multiple fixing columns 7 are evenly arranged in a circular array.

[0033] Furthermore, the end of the fixed column 7 facing away from the blade fixing ring 6 is rotatably connected to a rotating sleeve 8, and multiple inclined sliding groove rings 9 are fixedly connected to the inner wall of the medicine barrel 3. Multiple rotating sleeves 8 are slidingly connected to the inner wall of the corresponding inclined sliding groove ring 9. The fixed column 7 and the inclined sliding groove ring 9 are used to drive the blade paddle 5 on the blade fixing ring 6 to rotate and swing.

[0034] Furthermore, a feed port 15 is fixedly connected to the outer surface of the medicine barrel 3 , a discharge port 16 is fixedly connected to the center position of the lower end of the medicine barrel 3 , and two support frames 14 are fixedly connected to the lower surface of the drone mounting frame 2 .

[0035] Furthermore, mounting plates 10 are fixedly connected to the two support frames 14 respectively, the water pump 11 is fixedly installed on the mounting plate 10, and connecting water pipes 13 are fixedly connected between the output end of the water pump 11 and the discharge port 16.

[0036] Furthermore, spray nozzles 12 for spraying pesticides are fixedly connected to both output ends of the water pump 11, and the water pump 11 is used to extract pesticides from the medicine bucket 3.

[0037] Furthermore, during use, pesticides and water in corresponding proportions are poured into the medicine bucket 3 from the feed port 15. Then, by starting the servo push rod 4 provided, the output end of the servo push rod 4 will drive the blade paddle 5 and the multiple fixed columns 7 on the blade fixing ring 6 to move up and down together. At this time, since the rotating sleeve 8 is slidably connected to the inclined chute ring 9, and the inclined chute ring 9 is inclined, this enables the rotating sleeve 8 to drive the blade fixing ring 6 and the blade paddle 5 to rotate by a certain angle through the fixed column 7. At this time, the blade paddle 5 that rotates and descends at the same time can stir the liquid medicine in the medicine bucket 3 clockwise to a certain extent, so that a part of the liquid medicine can be mixed with the pesticides within the radial range of the medicine bucket 3, and a part of the liquid medicine will also flow into the upper space of the medicine bucket 3 from the blades of the blade paddle 5, so that the liquid medicine in the axial direction in the medicine bucket 3 can be evenly stirred. Another part of the liquid medicine will be forced by the downward force of the blade to flow into the upper space of the medicine bucket 3 from the outer edge of the blade fixing ring 6. During this process, the precipitated pesticides will be evenly mixed in the medicine bucket 3.

[0038] Furthermore, at this time, by starting the UAV body assembly 1, the UAV body assembly 1 drives the pesticide spraying assembly to fly to a designated position, and the water pump 11 is started. The water pump 11 pumps out the liquid medicine in the medicine bucket 3 for spraying. During the operation of the pesticide spraying assembly, it can make the pesticides be effectively mixed during the pesticide spraying process, which improves the mixing efficiency of the pesticides and also avoids the problem that in the traditional method of pesticide spraying, due to the lack of a mixing mechanism, the liquid medicine is prone to precipitation during drug spraying, resulting in uneven liquid medicine effect, and thus affecting the effect of the pesticides on plants.

[0039] Working principle: When in use, pour the pesticide and water in a corresponding proportion into the medicine barrel 3 from the feed port 15. Then, by starting the servo push rod 4 provided, the output end of the servo push rod 4 will drive the blade paddle 5 and multiple fixed columns 7 on the blade fixing ring 6 to move up and down together. At this time, due to the rotation sleeve 8 being slidably connected to the inclined chute ring 9, and the inclined chute ring 9 being inclined, this enables the rotation sleeve 8 to drive the blade fixing ring 6 and the blade paddle 5 to rotate a certain angle through the fixed column 7. At this time, the blade paddle 5 that rotates and descends at the same time can stir the liquid medicine in the medicine barrel 3 clockwise to a certain extent, so that a part of the liquid medicine can be mixed with the pesticide within the radial range of the medicine barrel 3, and there is still a part of the liquid medicine that will pour into the upper space of the medicine barrel 3 from the blades of the blade paddle 5, so that the liquid medicine in the axial direction in the medicine barrel 3 can be evenly stirred. There is still a part of the liquid medicine that will pour into the upper space of the medicine barrel 3 from the outer edge of the blade fixing ring 6 under the downward force of the blade. In this process, the precipitated pesticide will be evenly mixed in the medicine barrel 3.

[0040] Furthermore, at this time, by starting the unmanned aerial vehicle body assembly 1, the unmanned aerial vehicle body assembly 1 drives the pesticide spraying assembly to fly to a designated position, and starts the water pump 11. The water pump 11 pumps out the liquid medicine in the medicine barrel 3 for spraying. Under the operation of the pesticide spraying assembly, it can make the pesticide be effectively mixed during the process of spraying the pesticide, which improves the mixing efficiency of the pesticide.
