DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Example:

[0019] refer to Figures 1 to 4 The invention shows an agricultural drone spraying rack, comprising a sleeve 1, on the upper side of the outer surface of the sleeve 1, a fixing mechanism 2 suitable for quickly fixing the spraying rack to the base of the drone is fixedly installed, a conveying pipe 3 is fixedly connected to the upper surface of the sleeve 1, and a plurality of spray heads 4 are connected to the lower side of the sleeve 1; the fixing mechanism 2 comprises a fixing block 5; a semi-ring-shaped fixing clamp 13 is provided through the top of the fixing block 5, one end of the fixing clamp 13 is rotatably connected to a fixing semi-ring 7, and an oblique tooth 8 is provided on the outer arc surface of the fixing semi-ring 7; the fixing block 5 is provided with a mounting groove 6, and a fixing rod 9 is rotatably provided on the lower right side of the inside of the mounting groove 6, and a latch tooth 10 matching the oblique tooth 8 on the fixing semi-ring 7 is provided on the fixing rod 9, and a support spring 11 is fixedly connected to the side of the fixing rod 9 away from the fixing semi-ring 7, and the other end of the support spring 11 is connected to the inner wall of the mounting groove 6; the top of the fixing rod 9 is placed outside the mounting groove 6 and is connected to a handle 12. In actual use, when the spraying rack needs to be fixed on the base of the drone, it is only necessary to place the base of the drone in the fixing clamp 13, rotate the fixed half ring 7 so that the bevel teeth 8 on the fixed half ring 7 are engaged with the latch teeth 10 on the fixed rod 9. As pressure is further applied to the fixed half ring 7, due to the elastic potential energy of the support spring 11, when the fixed half ring 7 is rotated to drive the bevel teeth 8 to rotate, the latch teeth 10 miss the bevel teeth 8 one by one, and then under the action of the support spring 11, the latch teeth 10 are embedded in the grooves between the bevel teeth 8, so that the latch teeth 10 and the bevel teeth 8 are always in an engaged state until the inner side of the fixed half ring 7 contacts the base of the drone, thereby completing the fixation of the spray rack. When disassembly is required, it is only necessary to pull the handle 12 to release the engagement between the latch teeth 10 and the bevel teeth 8, so that the spray rack can be removed from the base of the drone, thereby improving the disassembly and assembly speed of the spray rack.

[0020] refer to Figure 4As shown, a rotation groove 21 is provided at one end of the fixed clamp 13, and rotation holes 22 are provided on opposite sides of the rotation groove 21. A connecting hole 23 is provided at one end of the fixed half ring 7. When the fixed half ring 7 is rotatably connected with the fixed clamp 13, one end of the fixed half ring 7 is placed in the rotation groove 21, and the rotation hole 22 is aligned with the connecting hole 23 and installed, and they are rotatably connected through a fixing bolt 24. By setting the rotation groove 21, the rotation hole 22 and the connecting hole 23 and rotatably connecting them through the fixing bolt 24, the rotation stability of the fixed half ring 7 is improved.

[0021] refer to Figure 1 , Figure 2 It is shown that when the fixing half ring 7 and the fixing clamp 13 are combined, the opposite sides cooperate to form a fixing ring hole; the fixing half ring 7 and the opposite sides of the fixing clamp 13 are fixedly connected with a rubber pad 14, and the fixing ring hole is formed by setting the fixing clamp 13 and the fixing half ring 7, thereby increasing the stability of the spray rack fixation. By setting the rubber pad 14, the material of the fixing half ring 7 and the fixing clamp 13 can be prevented from being too hard, causing wear to the base of the drone. At the same time, the rubber pad 14 has an anti-slip effect to prevent the spray rack from rotating around the fixing ring hole.

[0022] refer to Figure 2 , Figure 3 As shown, sliders 15 are respectively provided on the opposite sides of the fixing rod 9, and arc-shaped sliding grooves 16 matching the sliders 15 are respectively opened on the opposite sides of the inner wall of the mounting groove 6. When the fixing rod 9 is rotated in the mounting groove 6, the slider 15 slides and is placed in the arc-shaped sliding groove 16; in actual use, by setting the arc-shaped sliding groove 16 and the slider 15, the maximum rotation angle of the fixing rod 9 is limited, which can prevent the fixing rod 9 from being placed inside the mounting groove 6 under the action of the support spring 11 when the fixing half ring 7 is completely rotated away from the fixing clamp 13, thereby affecting subsequent installation.

[0023] refer to Figure 2 , Figure 3 As shown, a through hole 17 leading to the inner side of the fixing half ring 7 is opened through the top of the fixing half ring 7, an internal thread 18 is provided on the inner wall of the through hole 17, a fastening bolt 19 is threadedly connected to the through hole 17, the fastening bolt 19 passes through the through hole 17, and one end of the fastening bolt 19 that penetrates into the inner side of the fixing half ring 7 is rotated and provided with a protective pad 20. In actual use, the fastening bolt 19 is rotated to engage with the internal thread 18 on the inner wall of the through hole 17, so that the fastening bolt 19 moves toward the inner side of the fixing half ring 7 until the protective pad 20 contacts the base of the drone, preventing the fixing ring hole formed by the fixing half ring 7 and the fixing clamp 13 from sliding laterally on the base of the drone, affecting the stability of the spray frame, and by providing the protective pad 20, the base of the drone can be prevented from being worn by the fastening bolt 19.
