Description

Technical Field

[0001] The utility model relates to the field of agricultural unmanned aerial vehicles, in particular to a rotary spray head used for spraying pesticides on unmanned aerial vehicles. Background Art

[0002] Unmanned aircraft, also known as drones, are unmanned aircraft that are controlled by radio remote control equipment and the programs of their ancestors. Compared with manned aircraft, drones are often more suitable for tasks that are too dull, dirty or dangerous. With the development of the times, drones have been applied in aerial photography, agricultural plant protection, disaster relief, surveying and mapping, etc., which greatly expands the use of drones themselves;

[0003] Among them, the flight control of the drone is a key factor affecting the effect of pesticide spraying. In order to ensure the accuracy and stability of spraying, it is necessary to design the flight path and route according to the specific situation, and adjust it in combination with factors such as wind direction and temperature. In the case of unstable wind direction, large-scale spraying may lead to insufficient and incomplete spraying in some areas. At this time, it is necessary to carry out local spraying on farmland in some areas. In addition to ensuring the spraying efficiency, local spraying also needs to ensure the spraying range and whether the drone nozzle can adjust the direction so as to better carry out precise spraying of pests and diseases in the farmland in the future.

[0004] In view of this, we propose a rotary nozzle for drone spraying. Utility Model Content

The steering device 4 and the rotating rod 44 complete the steering of the inner nozzle 22. The inner nozzle 22 is arranged on the inner side of the nozzle housing 2. The top of the inner nozzle 22 is in contact with the inner top of the nozzle housing 2. A square hole 21 is provided on the upper outer wall of the nozzle housing 2. A square hole 221 is provided on the upper outer wall of the inner nozzle 22. The square hole 21 and the square hole 221 are in the same horizontal plane. A steering hose 3 is fixedly connected to the bottom of the nozzle housing 2. The nozzle housing 2 is fixedly connected to the pipeline housing 1 through the steering hose 3.

[0029] like Figure 3-5 As shown, a No. 1 sliding connection member 41 is provided in the steering device 4, and the upper end outer wall of the No. 1 sliding connection member 41 is fixedly connected to one end of a connecting column 42, and the other end of the connecting column 42 is fixedly connected to a No. 2 sliding connection member 43, and a rotating rod 44 is provided inside the No. 2 sliding connection member 43, wherein: one end of the rotating rod 44 is fixedly connected to one end of a bending connection member 441, and the other end of the bending connection member 441 is fixedly connected to a connecting disk 443, and the outer wall of the connecting disk 443 is fixedly connected to the inner wall of the inner nozzle 22 through a plurality of horizontal columns, and the other end of the rotating rod 44 A fixing member 442 is fixedly connected, one side of the fixing member 442 is fixedly connected to one end of a bending column 4421, and the other end of the bending column 4421 is fixedly connected to a sliding ball 4422. The outer wall of the lower end of the No. 1 sliding connection member 41 is provided with a No. 1 annular groove 411, and the height and width of the No. 1 annular groove 411 match the diameter of the buckle ring 15. The inner wall of the No. 2 sliding connection member 43 is provided with a No. 2 annular groove 431, and the height of the No. 2 annular groove 431 matches the diameter of the sliding ball 4422. The rotating rod 44 is rotatably connected to the inner side of the supporting member 121;

[0030] It can be seen from this that when spraying a local area, the direction of the nozzle needs to be adjusted, such as Figure 4As shown, the telescopic rod 13 is extended during spraying, and the extension of the telescopic rod 13 will drive the sliding control member 14 and the buckle ring 15 to move upward, and at the same time push the No. 1 sliding connector 41 and the No. 2 sliding connector 43 to slide upward on the hexagonal column 12, and at the same time the sliding ball 4422 in the No. 2 annular groove 431 moves upward with the No. 2 sliding connector 43, wherein the rotating rod 44 is used as a fulcrum, and the bending connector 441 will rotate downward, and the bending connector 441 will drive the connecting plate 443 to rotate downward, and the connecting plate 443 will rotate downward, and the entire inner nozzle 22 will be tilted at a certain angle in the opposite direction of the sliding ball 4422, and the inner nozzle 22 will be turned, because the nozzle is installed at the bottom of the propeller of the drone, during the rotation of the propeller, the entire device will also rotate together, and finally the medicine will be sprayed from the No. 2 square hole 221 to the No. 1 square hole 21;

[0031] It should be noted that: Figure 1 As shown, a certain gap is left between the top of the nozzle shell 2 and the top of the inner nozzle 22, and a portion of the medicine will be sprayed out from the gap between the nozzle shell 2 and the inner nozzle 22. At the same time, after the inner nozzle 22 is driven to rotate downward, the top of the inner nozzle 22 will drive the nozzle shell 2 to rotate. Because the steering hose 3 is a tubular and soft material, the rotation will not be blocked and unable to rotate.
