DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0035] The present utility model provides as Figures 1-5A pesticide spraying device for a plant protection UAV shown in the figure includes a UAV main body 1. A medicine box 2 is fixedly connected to the bottom of the UAV main body 1. A connecting bracket 4 is fixedly connected to the bottom of the UAV main body 1. Nozzles 3 are symmetrically arranged at the bottom of the connecting bracket 4. A self-priming pump is arranged on the medicine box 2. The self-priming pump is connected to the nozzles 3 through a hose. Thus, the self-priming pump transports the liquid medicine in the medicine box 2 to the nozzles 3 through the hose and sprays it out. An installation component 5 is arranged between the connecting bracket 4 and the UAV main body 1, and an adjusting component 6 is arranged between the connecting bracket 4 and the nozzles 3.

[0036] In particular, the installation component 5 includes a connecting frame 51 fixedly connected to the bottom of the UAV main body 1, a connecting plate 52 fixedly connected to the top of the connecting bracket 4. The connecting bracket 4 is slidably clamped to the connecting frame 51 through the connecting plate 52. The locking piece 53 is in an L shape and can clamp and restrain the connecting plate 52 to prevent the connecting plate 52 from separating from the connecting frame 51. Thus, the stability of the connecting bracket 4 installed at the bottom of the UAV main body 1 through the connecting plate 52 and the connecting frame 51 is ensured. The locking piece 53 is slidably connected to the inside of the connecting frame 51 to clamp and lock the connecting plate 52. The installation component 5 further includes a first slider 54 fixedly connected to the outer wall of the connecting plate 52. The outer wall of the first slider 54 is horizontally slidably clamped to the connecting frame 51. Thus, under the action of the first slider 54, the connecting plate 52 can be horizontally slid and separated or docked with the connecting frame 51. A second slider 55 is fixedly connected to the outer wall of the locking piece 53. The outer wall of the second slider 55 is vertically slidably clamped to the connecting frame 51. Under the action of the second slider 55, the locking piece 53 can only slide vertically up and down relative to the connecting frame 51.

[0037] Furthermore, the installation component 5 further includes a connecting block 56. One side of the connecting block 56 is fixedly connected to the locking piece 53. A sliding hole matching the connecting block 56 is opened on one side of the connecting frame 51. The button 57 can drive the locking piece 53 to rise and separate from the connecting plate 52 through the connecting block 56. Thus, by horizontally sliding the connecting plate 52, the connecting bracket 4 can be disassembled. One end of the button 57 is fixedly connected to the connecting block 56, a guide rod 58 and a limiting spring 59. Under the action of the limiting spring 59, the connecting block 56 can drive the locking piece 53 to maintain a stable clamping state with the connecting plate 52. The guide rod 58 is fixedly connected in the sliding hole to guide the connecting block 56, and the outer wall of the guide rod 58 is slidably inserted through the connecting block 56. The limiting spring 59 is slidably sleeved on the outer wall of the guide rod 58 to squeeze and limit the connecting block 56.

[0038] Further, the adjusting assembly 6 includes a connecting sleeve 61 which is rotatably sleeved on the outer wall of the connecting bracket 4. The spray head 3 rotates relative to the connecting sleeve 61 through a connecting shaft 62, so that the inclination angle of the spray head 3 can be changed. When the connecting sleeve 61 rotates relative to the connecting bracket 4, the orientation of the spray head 3 can be changed. The spray head 3 is rotatably connected to one side of the connecting sleeve 61 through the connecting shaft 62. The adjusting assembly 6 further includes a fixed sleeve 65 which is fixedly sleeved on the outer wall of the spray head 3. One side of the fixed sleeve 65 is fixedly connected to the connecting shaft 62. A brake pad 64 is fixedly connected to one end of the connecting shaft 62, and the brake pad 64 is rotatably connected to the inside of the connecting sleeve 61.

[0039] In particular, the adjusting assembly 6 further includes a limiting collar 66 which is rotatably sleeved between the connecting sleeve 61 and the connecting bracket 4. An outer annular groove matching the limiting collar 66 is formed on the outer wall of the connecting bracket 4, and an inner annular groove matching the limiting collar 66 is formed on the inner wall of the connecting sleeve 61. Thus, the limiting collar 66 can be used to clamp and limit the connecting sleeve 61, so that the connecting sleeve 61 and the connecting bracket 4 maintain a stable rotational connection state. When the locking bolt 63 is rotated, the locking bolt 63 presses the limiting collar 66, and the limiting collar 66 can press the brake pad 64 to brake the brake pad 64, thereby ensuring the stability of the angle of the spray head 3. The brake pad 64 is made of a soft material. Thus, when the locking bolt 63 presses the brake pad 64 through the limiting collar 66, the locking bolt 63 can also give a pressing force to the connecting sleeve 61, so that one side of the connecting sleeve 61 fits against the outer wall of the connecting bracket 4, thereby locking the connecting sleeve 61 again. The outer wall of the locking bolt 63 is threadedly inserted and sleeved with the connecting sleeve 61, and one end of the locking bolt 63 is in pressing fit with the limiting collar 66.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
