[0025] like Figure 1 - Figure 4 As shown, an automatic feeding device for a spraying drone includes a drone body 1, drone blades 2, a suspension box 3, and quick-release rods 4. The drone blades 2 are located at the four corners of the upper end of the drone body 1. The suspension box 3 is quickly installed at the lower end of the drone body 1 via the quick-release rods 4, allowing for convenient installation and removal.
[0026] Two parallel assembly rods 5 are provided at the lower end of the suspension box 3, and a buffer structure is provided on the rod body of each assembly rod 5; the two movable blocks 10 on the two buffer structures are connected by a mounting frame 12; a paint spray head 13 is installed at the lower end of the mounting frame 12, and the paint spray head 13 is connected to the feeding mechanism 15.
[0027] The buffer structure includes a movable block 10, a buffer spring 9 and a mounting block 7 which are sequentially mounted on the assembly rod 5; the movable block 10 is slidably connected to the assembly rod 5, and the two ends of the buffer spring 9 are respectively connected to the movable block 10 and the mounting block 7; the buffer spring 9 is mounted on the assembly rod 5, and the mounting block 7 is fixed on the assembly rod 5; the assembly rod 5 is divided into a threaded rod portion and a smooth rod portion, and the movable block 10 is slidably connected to the smooth rod portion on the assembly rod 5. When the spray head 13 is started to generate a backlash, the backlash is transmitted to the movable block 10, and the movable block 10 slides on the assembly rod 5, compressing the buffer spring 9. The buffer spring 9 absorbs and buffers the backlash through its own elastic deformation, thereby protecting the stable operation of the drone.
[0028] Further, the movable block 10 and the mounting block 7 are further provided with a stabilizing rod 11, which is arranged in parallel with the assembling rod 5; one side of the stabilizing rod 11 is slidably connected with the movable block 10, and the other side is fixed on the mounting block 7. The stabilizing rod 11 is in a round rod structure, and the middle part of the corresponding movable block 10 is provided with a through hole matched with the diameter of the stabilizing rod 11; the movable block 10 is slidably connected with the stabilizing rod 11 through the through hole, and slides along the stabilizing rod 11 under the driving of the mounting frame 12. The stabilizing rod 11 plays a guiding role, ensures that the movable block 10 can slide in a predetermined direction when subjected to a rear impact force, and further enhances the stability of the buffer structure during work, prevents the movable block 10 from deviating or shaking during sliding, and ensures that the buffer spring 9 can effectively play a buffering role.
[0029] Further, the suspension box 3 is installed at the lower end of the unmanned aerial vehicle body 1 through the quick mounting rod 4, and the lower end of the suspension box 3 is provided with a connecting block 6 at each corner; the upper end of the connecting block 6 is connected with the suspension box 3, and the lower end of the connecting block 6 is connected with the assembling rod 5. The connecting block 6 is connected with the suspension box 3 through bolts and nuts, the assembling rod 5 passes through the two connecting blocks 6 and is fixed through nuts, and the assembling rod 5 is divided into a threaded rod part and a smooth rod part, which can be used in cooperation with nuts for easy disassembly and maintenance. The inner hole of the fastening sleeve 8 is a threaded hole, the threaded rod part of the assembling rod 5 is threadedly connected with the fastening sleeve 8, and the fastening sleeve 8 is welded and fixed with the mounting block 7.
[0030] Further, the two ends of the mounting frame 12 are connected with the two movable blocks 10 through bolts, and the connecting lines of the mounting frame 12 and the two movable blocks 10 are perpendicular to each other. The connecting part of the movable block 10 and the mounting frame 12 is provided with a rubber gasket, which has good elasticity and damping characteristics. When the paint spraying head 13 works and vibrates, the vibration is transmitted to the movable block 10, and the rubber gasket can further absorb the vibration of the paint spraying head 13 during work, preventing the vibration from being transmitted to the unmanned aerial vehicle body 1 through the movable block 10 and the mounting frame 12, thereby ensuring the stability of the unmanned aerial vehicle flight.
[0031] The paint spraying head 13 is connected with the adapter 14 through a threaded pipe, and the feeding mechanism 15 is connected with the adapter 14 through a threaded pipe, realizing quick assembly of the paint spraying head 13 and the feeding mechanism 15, thereby realizing automatic feeding operation of the spraying unmanned aerial vehicle; this design not only improves the assembly efficiency, but also facilitates quick replacement of different paint spraying heads 13 and feeding mechanisms 15 in different operating environments, greatly improving the applicability and flexibility of the spraying unmanned aerial vehicle. The feeding mechanism 15 delivers paint to the paint spraying head 13, and the feeding mechanism 15 is a commonly used paint spraying device, and its specific structure is not described herein.
[0032] Working principle:
[0033] When the feed mechanism 15 begins to deliver paint to the paint spray head 13, the material flow accelerates upon activation, generating a backlash force. This backlash force acts on the paint spray head 13 and is then transmitted to the mounting bracket 12 and the movable block 10. Upon receiving this backlash force, the movable block 10 slides along the smooth portion of the assembly rod 5 and the stabilizer rod 11, compressing the buffer spring 9. The buffer spring 9 absorbs and cushions the backlash force through its elastic deformation, preventing it from directly impacting the drone's body and ensuring flight stability.
