[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an unmanned aerial vehicle-mounted tree barrier pruning electric saw, comprising an unmanned aerial vehicle main body 1, the unmanned aerial vehicle main body 1 is a prior art, through which elevated tree barriers can be pruned, thereby improving pruning efficiency, and it can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A slider 7 is fixedly connected to the lower surface of the unmanned aerial vehicle main body 1, and a mounting plate 6 is slidably connected to the lower surface of the slider 7. The slider 7 is trapezoidal in shape and is adapted to the inner wall of the mounting plate 6 to ensure the stability of the connection. A buffer component is provided on the inner wall of the mounting plate 6, and a mounting component is provided on the lower surface of the mounting plate 6. A swing-stop platform 4 is provided at the bottom end of the mounting component. The swing-stop platform 4 is a prior art, which can prevent the pruning main body 3 and the boom 2 from swinging too much, and it can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. No further description will be given in the case. The bottom end of the anti-swing platform 4 is fixedly connected to the suspension rod 2 by bolts. The bottom end of the suspension rod 2 is provided with a roller, which has the function of assisting the descent and improves the practicality. The inner wall of the bottom end of the suspension rod 2 is plugged with a pruning body 3. The pruning body 3 is the prior art. A saw blade is provided on its lower surface and a triangular branch separator is provided on its left surface.

The mounting assembly includes a rectangular shell 52, which is fixedly connected to the lower surface of the mounting plate 6. The inner wall of the front end of the rectangular shell 52 contacts with a plug-in plate 51. The bottom end of the plug-in plate 51 is fixedly connected to the top of the anti-swing platform 4 by bolts. It is fixed by bolts, which is convenient for disassembly of the component and improves the practicality. The front end of the right surface of the rectangular shell 52 is fixedly connected with a fixing block 57.

[0034] Reference Figure 1 - Figure 2 , Figure 4The buffer assembly includes a sleeve 81, and the inner wall of the sleeve 81 is divided into left and right chambers to ensure the buffering effect. The sleeve 81 is slidably connected to the inner wall of the mounting plate 6. A sliding rod 82 is slidably connected to the left surface of the sleeve 81, and a piston block 83 is fixedly connected to the right surface of the sliding rod 82. When the piston block 83 moves on the inner wall of the sleeve 81, the air on the inner wall of the sleeve 81 will be driven to flow. The flowing air will generate a certain resistance through the air hole 1 85 and the air hole 2 86, which can offset the external impact force and improve the practicality. The piston block 83 is connected to the inner wall of the sleeve 81, and a spring 2 84 is fixedly connected to the right surface of the piston block 83. The spring 2 84 can buffer the external impact force through its own elasticity, and the right end of the spring 2 84 is fixedly connected to the inner wall of the sleeve 81.

[0035] Reference Figure 2 , Figure 5 - Figure 6 The front surface of the fixed block 57 is rotatably connected with a bidirectional threaded rod 58, which is a prior art. Since it is a prior art, it will not be described in detail in this case. At the same time, it has the characteristic of axial self-locking to ensure the stability of the structural connection. The outer wall of the bidirectional threaded rod 58 is threadedly connected with a connecting plate 59, which is slidably connected to the right surface of the rectangular shell 52. The connecting plate 59 slides forward or backward. The front surface of the left end of the connecting plate 59 is fixedly connected with a plug-in board 2 510, and the plug-in board 2 510 is adapted to the inner wall of the plug-in board 1 51 to ensure the stability of the connection. The plug-in board 2 510 is slidably connected to the inner wall of the rectangular shell 52, and the front end of the plug-in board 2 510 contacts the inner wall of the plug-in board 1 51. The inner wall of the front end of the rectangular shell 52 is elastically connected to the limit block 55 through a spring 1 56. The spring 1 56 always pushes the limit block 55 to move to the right through its own elasticity to ensure its limit stability. The limit block 55 is slidably connected to the inner wall of the front end of the rectangular shell 52, one end of the spring 1 56 is fixedly connected to the inner wall of the front end of the rectangular shell 52, and the other end of the spring 1 56 is fixedly connected to the left surface of the limit block 55. The right end of the limit block 55 slides on the inner wall of the fixed block 57.

[0036] Reference Figure 2 , Figure 5The outer wall of the front end of the two-way threaded rod 58 is fixedly connected with a gear 511. The gear 511 is a prior art and its outer wall is provided with multiple sets of teeth. At the same time, the size of the teeth on the outer wall is adapted to the left surface of the limit block 55 and can mesh together to ensure the stability of the limit block 55. The gear 511 is rotatably connected to the inner wall of the fixed block 57, and the gear 511 contacts the right surface of the limit block 55. A through groove 53 is provided on the front surface of the rectangular shell 52, and the through groove 53 is L-shaped. When the limit block 55 is released, the push plate 54 can be stuck at the bottom end of the left side of the through groove 53 to prevent the limit block 55 from resetting. In this way, the worker can safely rotate the two-way threaded rod 58 to improve practicality. The inner wall of the through groove 53 is slidably connected with a push plate 54. The rear surface of the push plate 54 is slidably connected to the left end of the front surface of the limit block 55. The push plate 54 slides upward or downward at the left end of the front surface of the limit block 55.

[0037] Reference Figure 4 , Figure 7 The inner wall of the sleeve 81 is provided with a second air hole 86, and the front surface of the sleeve 81 is provided with an air hole 1 85. The air hole 1 85 is connected with the air hole 2 86. When the piston block 83 moves, the air on the inner wall of the sleeve 81 will be squeezed, and the squeezed air will collide with the inner wall of the second air hole 86 and be discharged through the first air hole 85, thereby improving the damping performance. There are multiple groups of sliding rods 82, piston blocks 83, and second springs 84, and the multiple groups of sliding rods 82, piston blocks 83, and second springs 84 are symmetrically arranged with the center line of the sleeve 81 as the symmetry axis. The right surfaces of the multiple groups of sliding rods 82 are fixedly connected to the left surface of the slider 7. With the cooperation of the multiple groups of sliding rods 82, piston blocks 83, and second springs 84, the buffering effect can be improved.

[0038] Working principle: When it is necessary to trim tree obstacles, the drone body 1, the boom 2, the trimming body 3, and the anti-swing gimbal 4 can be installed. You only need to insert the trimming body 3 into the inner wall at the bottom of the boom 2, fix it with the quick-release pin, and then use the bolts to fix the boom 2 and the anti-swing gimbal 4 together. Use the bolts to fix the plug-in board 51 to the top of the anti-swing gimbal 4, and then insert the plug-in board 51 into the inner wall of the rectangular shell 52, and then push the push plate 54. The push plate 54 will drive the limit block 55 to move, and the limit block 55 will squeeze the spring 56 until the limit block 55 is disengaged from the gear 511. At this time, push the push plate 54 The two-way threaded rod 58 is then rotated by being stuck in the bottom end on the left side of the through slot 53. At this time, the connecting plate 59 threadedly connected to the outer wall of the two-way threaded rod 58 will move linearly, and the connecting plate 59 will drive the second plug-in plate 510 to move, so that the second plug-in plate 510 is inserted into the inner wall of the first plug-in plate 51, and then the push plate 54 is pushed out from the inner wall of the bottom end of the left side of the through slot 53. At this time, the spring 1 56 will push the limit block 55 to move in the opposite direction through its own elasticity, so that the limit block 55 is meshed with the gear 511, thereby preventing the two-way threaded rod 58 from rotating in the opposite direction due to vibration, thereby improving stability. In this way, it is installed and the drone body 1 can be started for operation.

[0039] When pruning, when the pruning body 3 touches the tree barrier, a certain impact force will be generated, and the impact force will cause the mounting plate 6 and the slider 7 to slide, so that the slide rod 82 will drive the piston block 83 to perform piston movement on the inner wall of the sleeve 81. The piston block 83 squeezes the air and squeezes or stretches the spring 2 84. The squeezed air will be discharged through the air hole 2 86 and the air hole 1 85. When exhausting and inhaling, a certain resistance will be generated, which can buffer the impact force and improve practicality.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
