[0009] An air flow hole is provided on the outer wall of the first air bag.

[0010] Preferably, a buffer pad is fixedly connected to the bottom of the connecting frame, and a bracket is fixedly connected to the outer wall of the frame.

[0011] Preferably, a fan is fixedly connected to the outer wall of the bracket, the bottom of the fan is fixedly connected to the mounting plate, and a hole is opened at the top of the first airbag at a position inside the mounting plate.

[0012] Preferably, the first airbag outer wall is located at the positions of the two airflow holes and is respectively fixedly connected with a first zigzag tube and a second zigzag tube, and the first airbag inner wall is located between the two airflow holes and is fixedly connected with a long rod.

[0013] Preferably, the outer wall of the long rod is rotatably connected to two plug-in plates, and a first spring is fixedly connected between the two plug-in plates and the long rod respectively.

[0014] Preferably, holes are formed on the outer walls of the plug-in board, and the second limiting rod and the first limiting rod are respectively inserted into the holes of the plug-in board.

[0017] Preferably, a buffer mechanism is fixedly connected to the bottom of the first airbag, and the buffer mechanism includes a second airbag. A hole is opened at the bottom of the first airbag, and the second airbag is fixedly connected to the position of the hole in the bottom of the first airbag. A second spring is fixedly connected to the inner top of the mounting plate, and a blocking plate is fixedly connected to the bottom of the second spring, and the blocking plate is located inside the second airbag.

[0018] Preferably, a hole is opened at the bottom of the second airbag, a film layer is fixedly connected in the hole of the second airbag, an elastic plate is fixedly connected to the bottom of the second airbag near the film layer, a breaking thorn is fixedly connected to the top of the elastic plate, and the breaking thorn is in active contact with the film layer.

[0019] The present invention provides a smart agricultural drone with a shock-absorbing structure. It has the following beneficial effects:

[0020] 1. The smart agricultural drone with a shock-absorbing structure inflates the first airbag through airflow. The inflated first airbag can provide buffering when it contacts the ground. The inflated first airbag cooperates with the inflated second airbag. The setting of the two-layer airbag can effectively buffer the descent of the frame and effectively protect the electronic components in the frame. The gas in the first airbag will also extend the first and second zigzag tubes. The extended first and second zigzag tubes will first contact the ground and also play a buffering role, thereby increasing the buffering effect on the frame and effectively extending the service life of the electronic components in the frame. When the first friction block and the second friction block contact the ground, the first friction block and the second friction block may get stuck in the potholes on a pothole road surface, thereby preventing the frame from moving again. When encountering a normal road surface, the first friction block and the second friction block will also rub against the ground, thereby reducing the activity of the frame and reducing the impact of wind on the frame.

[0021] 2. The smart agricultural drone with a shock-absorbing structure uses a fan to suck the mounting plate to shrink the first airbag. When the first zigzag tube and the second zigzag tube first touch the ground, they are squeezed by the ground and separated. Then, the first airbag shrinks while also driving the first and second zigzag tubes to shrink. The first spring pulls the first limit rod and the first friction block closer together, and then the second friction block and the first friction block are brought closer together to clamp the ground, which can effectively increase the contact between the frame and the ground and prevent the frame from tilting and falling.

[0022] 3. The smart agricultural drone with a shock-absorbing structure utilizes the increased gas in the first airbag. When the frame cannot effectively buffer the falling speed, the falling frame will drive the elastic plate to bend when it hits the ground. The bent elastic plate will drive the piercing thorns to squeeze onto the film layer, and then the piercing thorns will pierce the film layer. The squeezed gas in the second airbag will be ejected from the bottom of the second airbag. At this time, the airflow blows toward the ground, which plays a buffering role and utilizes the anti-impact force of the airflow to effectively protect the frame.

[0023] 4. The smart agricultural drone with a shock-absorbing structure monitors the environment through an agricultural monitor, and then the camera device can take pictures and transmit them to the terminal through a network module, achieving the effect of intelligent monitoring.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. Embodiment 1

[0035] See also Figure 1-6 The present invention provides a technical solution: a smart agricultural drone with a shock-absorbing structure, comprising a frame 2, an agricultural monitor 1 is fixedly connected to the top of the frame 2, a connecting frame 4 is fixedly connected to the outer wall of the frame 2, a camera device 3 is fixedly connected to the outer wall of the connecting frame 4, a power device 5 is fixedly connected to the end of the connecting frame 4, a fan blade 6 is rotatably connected to the outer wall of the power device 5, a mounting plate 12 is fixedly connected to the bottom of the frame 2, and a friction mechanism 7 is fixedly connected to the bottom of the mounting plate 12;

[0036] The friction mechanism 7 comprises:

[0037] A first airbag 71, the first airbag 71 is fixedly connected to the bottom of the mounting plate 12;

[0038] The air flow hole 72 is opened on the outer wall of the first air bag 71 .

[0039] A buffer pad 11 is fixedly connected to the bottom of the connecting frame 4 , and a bracket 9 is fixedly connected to the outer wall of the frame 2 .

[0040] The outer wall of the bracket 9 is fixedly connected with the fan 10 , the bottom of the fan 10 is fixedly connected with the mounting plate 12 , and a hole is opened at the top of the first airbag 71 located inside the mounting plate 12 .

[0041] The first airbag 71 has an outer wall located at the positions of the two air holes 72 with a first zigzag tube 75 and a second zigzag tube 710 fixedly connected thereto respectively. The first airbag 71 has an inner wall located between the two air holes 72 with a long rod 77 fixedly connected thereto.

[0042] The outer wall of the long rod 77 is rotatably connected to two plug-in plates 73 , and a first spring 78 is fixedly connected between the two plug-in plates 73 and the long rod 77 .

[0043] The outer wall of the plug-in board 73 is provided with holes, and the second limiting rod 79 and the first limiting rod 74 are respectively inserted into the holes of the plug-in board 73.

[0044] The bottom of the second limiting rod 79 is fixedly connected to the inner bottom of the second zigzag tube 710 , and the bottom of the first limiting rod 74 is fixedly connected to the inner bottom of the first zigzag tube 75 .

[0045] A first friction block 76 is fixedly connected to the bottom of the first zigzag tube 75 , and a second friction block 711 is fixedly connected to the bottom of the second zigzag tube 710 .

[0046] When in use, the power device 5 drives the fan blades 6 to rotate, which will then drive the frame 2 to start, the agricultural monitor 1 monitors the environment, and then the camera device 3 can take pictures and transmit them to the terminal through the network module. Before descending to the ground during the detection process, the fan 10 is powered on and started, and the fan 10 conveys airflow to the first airbag 71. The airflow causes the first airbag 71 to swell, and the swollen first airbag 71 can provide buffering when it contacts the ground. At this time, the gas in the first airbag 71 will also stretch the first and second zigzag tubes 75 and 710. The stretching of the first and second zigzag tubes 75 and 710 will first contact the ground, which will also play a buffering role. Then the second friction block 711 and the first friction block 76 are arranged at the bottom of the second zigzag tube 710 and the first zigzag tube 75. When the first friction block 76 and the second friction block 711 contact the ground, the first friction block 76 and the second friction block 711 are on the bumpy road surface. , it may get stuck in the pothole and prevent the frame 2 from moving again. When encountering a normal road surface, the first friction block 76 and the second friction block 711 will also rub against the ground. After the frame 2 falls to the ground, the fan 10 suctions the mounting plate 12 to shrink the first airbag 71. When the first zigzag tube 75 and the second zigzag tube 710 first touch the ground, they will be squeezed by the ground and separated. Then, the first airbag 71 shrinks and the first zigzag tube 75 and the second zigzag tube 710 will shrink. At this time, the elasticity of the first spring 78 pulls the plug-in plate 73 to reset, and at this time, the first limit rod 74 and the first friction block 76 are pulled close, so that the second friction block 711 and the first friction block 76 are close to each other to clamp the ground. The first limit rod 74 and the second limit rod 79 are both plugged into the plug-in plate 73, so the second limit rod 79 and the first limit rod 74 can be located in the plug-in plate 73 and move. Embodiment 2

[0047] See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0048] The bottom of the first airbag 71 is fixedly connected to a buffer mechanism 8, and the buffer mechanism 8 includes a second airbag 81. A hole is opened at the bottom of the first airbag 71, and the second airbag 81 is fixedly connected to the position of the bottom hole of the first airbag 71. The inner top of the mounting plate 12 is fixedly connected to a second spring 82, and the bottom of the second spring 82 is fixedly connected to a blocking plate 83, and the blocking plate 83 is located inside the second airbag 81.

[0049] A hole is provided at the bottom of the second airbag 81, a film layer 84 is fixedly connected in the hole of the second airbag 81, an elastic plate 86 is fixedly connected at the bottom of the second airbag 81 near the film layer 84, a breaking thorn 85 is fixedly connected to the top of the elastic plate 86, the breaking thorn 85 is in active contact with the film layer 84, and the film layer 84 can be replaced later.

[0050] When in use, the fan 10 first delivers gas to the first airbag 71. When the gas in the first airbag 71 increases to a certain amount, the gas will enter the second airbag 81 through the hole between the first airbag 71 and the second airbag 81, and then make the second airbag 81 swell. The hole diameter at the bottom of the first airbag 71 is smaller than the diameter of the blocking plate 83, so the blocking plate 83 will prevent the gas entering the second airbag 81 from flowing into the first airbag 71 again. When the frame 2 falls to the ground, if the contact force with the ground is too large, it is large enough to drive the elastic plate 86 to bend. At this time, the bent elastic plate 86 will drive the rupture thorn 85 to squeeze onto the film layer 84, and then the rupture thorn 85 pierces the film layer 84, and the squeezed gas in the second airbag 81 is ejected from the bottom of the second airbag 81. At this time, the airflow blows to the ground, thereby playing a buffering role. Embodiment 3
