Description

Technical Field

[0001] The invention relates to the technical field of drug spraying, and in particular to a forestry unmanned aerial vehicle spraying device. Background Art

[0002] When spraying pesticides on large rows of saplings or trees, drones are usually used. Workers remotely control the drones to spray pesticides on the trees, which improves work efficiency on the one hand and safety on the other.

[0003] However, conventional drone spraying devices usually install nozzles around the drone, that is, below the propellers around the drone. Generally, a drone has four propellers, and the nozzles are located below the propellers and cannot be adjusted. In this case, whether the drone flies horizontally or vertically, the spraying trajectories of the two rear nozzles and the two front nozzles in the forward direction will always be repeated. Although the spraying amount of the sprayed area can be increased, it often causes excessive or wasteful spraying of the drug. The front and rear four nozzles cannot be adjusted according to the forward direction of the drone to avoid the repetition of the spraying areas of the front and rear nozzles in the forward direction, thereby increasing the spraying range and reducing waste.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1-Figure 11As shown, a forestry UAV spraying device comprises a UAV body 1 and a liquid storage tank 2 arranged on the UAV body 1, a water pump 3 is arranged at the bottom of the liquid storage tank 2, a U-shaped tube 1 4 is arranged at the bottom of the water pump 3, both ends of the U-shaped tube 1 4 are penetrated and fixedly connected with a U-shaped tube 2 5, and two groups of spraying structures 6 are arranged outside the UAV body 1;

[0038] The spraying structure 6 includes two bottom plates 9 and a storage box 11. The bottom plates 9 and the storage box 11 are fixedly connected to the drone body 1. A storage rack 10 is fixedly connected between the bottoms of the two bottom plates 9. Two sliders 12 are slidably arranged on the inner side of the storage rack 10. A movable plate 13 is rotatably connected to the bottom of the slider 12. A nozzle 14 is fixedly arranged at the bottom of the movable plate 13. A connecting pipe 15 is fixedly connected to the outside of the nozzle 14. A motor 16 is arranged on the top of the storage box 11. The output shaft of the motor 16 passes through the top of the storage box 11 and is fixedly connected to a gear plate 17. The gear plate 17 is meshedly connected to two sawtooth plates 18. Two limit blocks 19 and a linkage rod 20 are fixedly connected to the outside of the sawtooth plate 18. One end of the linkage rod 20 passes through the storage box 11 and is fixedly connected to a connecting plate 21. The connecting plate 21 is fixedly connected to the slider 12 at the corresponding position.

[0039] The spraying structure 6 can adjust the positions of the nozzles 14 on both sides of the drone body 1, so that the two nozzles 14 at the corresponding positions can move toward the middle of the rack 10 or move away from the two ends of the rack 10, thereby preventing the front two nozzles 14 and the rear two nozzles 14 from repeatedly spraying the same area when the drone body 1 is flying horizontally.

[0040] In this embodiment, the interior of the storage box 11 is hollow, and the serrated plate 18 , the linkage rod 20 and the storage box 11 are adaptively matched.

[0041] The storage box 11 protects the gear plate 17 and the serrated plate 18 from rusting due to the influence of external weather such as rain, thereby affecting the work.

[0042] In this embodiment, the length of one connecting plate 21 is longer than the length of another connecting plate 21 , and the four bottom plates 9 are respectively located around the drone body 1 .

[0043] The two sawtooth plates 18 are staggered in opposite directions, and the two connecting plates 21 are of different lengths to match the corresponding sawtooth plates 18 .

[0044] In this embodiment, a liquid inlet is provided on the top of the liquid storage box 2, and before the device is operated, an infusion tube is externally connected between the U-shaped tube 5 and the connecting tube 15.

[0045] The drug liquid is poured in from the liquid inlet, and the setting of the U-shaped tube 2 5 is convenient for adapting to the connecting tube 15.

[0046] In this embodiment, two groups of adjustment structures 7 are provided on the outside of the drone body 1, and the adjustment structure 7 includes a storage plate 22, which is fixedly connected to the drone body 1, and a multi-stage electric push rod 23 is provided on the inner bottom surface of the storage plate 22. One end of the multi-stage electric push rod 23 is fixedly connected to a fixing frame 24, and both ends of the fixing frame 24 are rotatably connected to a connecting arm 25, one end of the connecting arm 25 is rotatably connected to a multi-stage telescopic rod 26, and one end of the multi-stage telescopic rod 26 is fixedly connected to a connecting plate 27, and the connecting plate 27 is fixedly connected to the movable plate 13 at the corresponding position.

[0047] The adjustment structure 7 can make up for the shortcomings of the spraying structure 6, so that the nozzles 14 at the front and rear parts of the drone body 1 can be adjusted in angle, so that the two nozzles 14 at the corresponding positions can rotate toward the two ends of the drone body 1 at the same time, and can also rotate toward the direction of the drone body 1 at the same time, which can ensure that when the drone body 1 is in the longitudinal direction, the front two nozzles 14 and the rear two nozzles 14 will not repeatedly spray the same area. The adjustment structure 7 cooperates with the spraying structure 6 to increase the range of drug spraying and avoid the situation where the four front and rear nozzles 14 of the drone body 1 in the forward direction repeatedly spray the same area.

[0048] In this embodiment, the adjustment structure 7 also includes two protrusions 28, which are fixedly connected to the storage plate 22, and a sliding rod 29 is fixedly connected between the two protrusions 28. A sliding block 30 is provided on the outside of the sliding block 29 for sliding, and the sliding block 30 is fixedly connected to the fixing frame 24.

[0049] The slide bar 29 cooperates with the slider 2 30 to play an auxiliary limiting role on the fixing frame 1 24 , so that the up and down movement of the fixing frame 1 24 can be restricted, and the stability of the movement of the fixing frame 1 24 can be further enhanced.

[0050] In this embodiment, the storage plate 1 22 and the sliding block 2 30 are both L-shaped, and the storage plate 1 22 and the connecting arm 25 are both provided with a ventilation slot 1 on their exteriors.

[0051] The slider 2 30 has a limiting effect on the fixing frame 1 24 .

[0052] In this embodiment, two sets of auxiliary structures 8 are provided on the top of the storage rack 10, and the auxiliary structure 8 includes a second storage plate 31. The second storage plate 31 is fixedly connected to the storage rack 10, and a plurality of hooks 32 are fixedly connected to the bottom of the second storage plate 31. A fixed block 33 is fixedly connected to the inner side of the hook 32. A guide rod 34 is connected to the top of the fixed block 33, and a baffle 35 is fixedly connected to one end of the guide rod 34. A spring 36 is provided between the baffle 35 and the fixed block 33.

[0053] The auxiliary structure 8 can arrange the external infusion tube to avoid large-scale shaking during flight that affects the spraying and flight stability, and can also provide auxiliary support for the infusion tube.

[0054] In this embodiment, the spring 36 is located at the periphery of the corresponding guide rod 34 , and the second storage plate 31 is L-shaped.

[0055] The spring 36 provides elastic support for the baffle 35 .

[0056] In this embodiment, four fixing frames 37 are arranged at the bottom of the drone body 1, two storage rings 38 are fixedly connected to the bottom of the fixing frames 37, the fixing frames 37 are U-shaped, and two ventilation slots 38 are arranged outside the fixing frames 37.

[0057] The second fixing frame 37 and the storage ring 38 can limit and support one end of the infusion tube, and can guide the route of the infusion tube in cooperation with the auxiliary structure 8.

[0058] It should be noted that the present invention is a forestry drone spraying device. Before use, the drone spraying device is placed in an open space where spraying is required, and the drug liquid is poured into the liquid inlet of the drone body 1. After the liquid storage tank 2 is filled, the liquid inlet is closed, and then an infusion tube is externally connected between the U-shaped tube 2 5 and the connecting tube 15. After the nozzle 14 is adjusted to a predetermined position or angle, it can reach the working operating conditions, and the staff can remotely control it to perform drug spraying operations. In addition, Figure 1 , Fig.10 as well as Fig.11 is the initial state of the device;

[0059] In the initial state, when installing the infusion tube, first connect one end of the infusion tube to the corresponding position of the U-shaped tube 25, pass the other end of the infusion tube through the corresponding storage ring 38, and then pull up the guide rod 34 at the corresponding position, so that the baffle 35 releases the restriction on the hook 32, put the infusion tube into the corresponding hook 32, and then release the guide rod 34. The spring 36 makes the baffle 35 and the guide rod 34 rebound to the initial position and restrict the infusion tube to the inside of the hook 32. After the infusion tube is put into the corresponding hook 32, connect the other end of the infusion tube to the connecting tube 15, and the connection and installation of the infusion tube can be completed.

[0060] In the initial state, when adjusting the angle position of the two nozzles 14 at the front of the drone body 1, first start the multi-stage electric push rod 23 at the front of the drone body 1, so that it acts on the fixed frame 1 24 to move the corresponding two connecting arms 25 downward toward the storage plate 1 22, and the connecting arm 25 acts on the multi-stage telescopic rod 26 to move toward the movable plate 13, and the multi-stage telescopic rod 26 acts on the movable plate 13 through the connecting plate 2 27 to rotate the nozzle 14 in the opposite direction toward the fixed frame 1 24, until the nozzle 14 rotates to a predetermined angle and stops. At this time, the two nozzles 14 at the front of the drone body 1 are obviously tilted toward the two ends of the drone body 1 compared to the initial state when they are perpendicular to the ground;

[0061] In the initial state, when adjusting the angle position of the two nozzles 14 at the rear of the drone body 1, the multi-stage electric push rod 23 at the rear of the drone body 1 is started to act on the fixed frame 1 24 to move the corresponding two connecting arms 25 in the opposite direction of the storage plate 1 22, and the connecting arm 25 acts on the multi-stage telescopic rod 26 to move in the direction of the fixed frame 1 24, and the multi-stage telescopic rod 26 acts on the movable plate 13 through the connecting plate 2 27 to rotate the nozzle 14 in the direction of the fixed frame 1 24 until the nozzle 14 rotates to a predetermined angle and stops. At this time, the two nozzles 14 at the rear of the drone body 1 are obviously tilted toward the middle direction of the drone body 1 compared to the initial state when they are perpendicular to the ground;

[0062] In the initial state, the positions of the two nozzles 14 on one side of the drone body 1 are adjusted, and when the two nozzles 14 are brought closer to the middle position of the rack 10, the motor 16 on one side of the drone body 1 is started to act on the gear plate 17 to rotate, and the gear plate 17 drives the two sawtooth plates 18 to mesh and move, and the two sawtooth plates 18 drive the slider 12 at the corresponding position through the linkage rod 20 and the connecting plate 1 21 at the corresponding position, until the two sliders 12 drive the nozzles 14 at the corresponding position to move to the middle direction of the rack 10 through the movable plate 13 at the corresponding position and stop at the predetermined position. At this time, the two nozzles 14 on one side of the drone body 1 are obviously closer to the middle direction of the rack 10 compared with the initial position. In the process, the movable plate 13 acts on the multi-stage telescopic rod 26 at the corresponding position through the connecting plate 2 27 to shrink;

[0063] At this time, the positions of the two nozzles 14 at the front and rear parts of the drone body 1 and the two nozzles 14 on one side of the drone body 1 have been adjusted. Therefore, whether viewed from the front and rear parts of the drone body 1 or from both sides of the drone body 1, the position angles of the four nozzles 14 are different. When the drone body 1 flies longitudinally or laterally, there will be no repeated spraying in the same area in the forward direction of the drone body 1, so that the four nozzles 14 can perform their respective functions and avoid waste caused by repeated spraying. In addition, the drone body 1 is not only able to adjust the positions of the two nozzles 14 on one side, but can also adjust the two nozzles 14 on the other side of the drone body 1 as needed, as long as the spraying areas of the four nozzles 14 are not repeated.
