At the same time, the existing pesticide spraying UAV is easy to occur due to no buffer when landing, which will cause the UAV to be damaged and cause economic losses. Therefore, a protection device for a pesticide spraying UAV is urgently needed. Content of the Utility Model

Motors and installers are fixedly installed on the outer walls of both sides of the fuselage. Protection components are arranged on the outer walls of the motors and installers.

Moreover, the shock-absorbing pad can play a buffering role when contacting the ground and can protect the device, solving the problem that the existing pesticide spraying unmanned aerial vehicle may collide during operation, resulting in yaw of the unmanned aerial vehicle and the inability to continue the pesticide spraying work.

[0013] 2. For the protection device of the pesticide spraying unmanned aerial vehicle, by emitting a signal through the remote control terminal, the motor can be started, thereby driving the connecting rod to rotate, enabling the rotor to blow the pesticide during pesticide spraying, making the pesticide spraying more uniform. At the same time, when the humidity sensor detects that the humidity is lower than the specified value, it will emit a signal, causing the electric heating rod embedded in the inner cavity of the central shaft to start working, and the hot air will be dissipated outward through the ventilation grooves, drying the moisture on the surface of the rotor. Furthermore, the service life of the rotor can be effectively extended, and at the same time, it can effectively prevent the situation that the moisture on the surface of the rotor increases the overall weight and affects flight.

[0024] With the above structure, through the settings of the gyroscope 9 and the accelerometer 10, the device can achieve the purpose of automatic flight, and the flight is stable, effectively ensuring the success of pesticide spraying.

[0025] In a preferred embodiment, the shock-absorbing assembly 2 includes a small motor 201. A rotating shaft 202 is fixedly assembled to the power output shaft of the small motor 201. A sleeve 203 is fixedly sleeved on the outer wall of the rotating shaft 202. A bracket 204 is fixedly installed on the outer wall of the sleeve 203. A support leg 205 is fixedly installed at the bottom of the bracket 204. A shock-absorbing pad 206 is snap-fitted to the bottom of the support leg 205;

[0026] In a preferred embodiment, the number of the shock-absorbing assemblies 2 is two groups, and the two groups of shock-absorbing assemblies 2 are symmetrically distributed at the bottom of the machine body 1. The small motor 201 is fixedly installed on the inner wall of the long groove 4, and the small motor 201 is electrically connected to the distance sensor 3. The length of the shock-absorbing pad 206 is longer than that of the support leg 205. A shock absorber is installed in the inner cavity of the support leg 205;

[0027] With the above structure, due to the characteristic that a shock absorber is installed in the inner cavity of the support leg 205, it can be known that when the device lands, it can absorb the impact force during landing, so as to achieve the purpose of shock absorption. At the same time, by detecting the distance from the ground through the distance sensor 3, the distance sensor 3 can emit a signal, so that the small motor 201 can be started, and the rotating shaft 202 can be driven to rotate, so that the bracket 204 can drive the support leg 205 to rotate outwards, and the included angle between the two support legs 205 can be slowly increased, so that the overall height of the device is reduced, and the shock-absorbing pad 206 can play a buffering role when contacting the ground, and thus it can play a protective role for the device.

[0028] In a preferred embodiment, the protection assembly 6 includes a connecting rod 601. A protective circle 602 is fixedly assembled on the outer wall of the connecting rod 601. A central shaft 603 is installed at the bottom of the protective circle 602. An installation block 604 is fixedly sleeved on the outer wall of the central shaft 603. One end of a round rod 605 is fixedly installed on the outer wall of the installation block 604. A rotor 607 is fixedly assembled at the other end of the round rod 605. A ventilation groove 606 is opened on the outer wall of the central shaft 603. A protective cover 608 is fixedly installed at the top of the protective circle 602;

[0029] With the above structure, through the setting of the protective cover 608, it can effectively reduce the damage during collision and protect the interior from rain, dust and other environmental factors.

[0030] In a preferred embodiment, the number of the protection assemblies 6 is four groups, and the four groups of protection assemblies 6 are respectively installed on the outer walls of the motor 5 and the installer 7. One end of the connecting rod 601 far from the protective circle 602 is fixedly assembled to the power output shaft of the motor 5. An electric heating rod is embedded in the inner cavity of the central shaft 603, and the electric heating rod is electrically connected to the humidity sensor installed on the inner wall of the machine body 1;

[0031] Using the above structure, by transmitting a signal through the remote control terminal, the motor 5 can be started, so that the connecting rod 601 can be driven to rotate, enabling the rotor 607 to blow the pesticide during pesticide spraying, making the pesticide spraying more uniform. At the same time, when the humidity sensor detects that the humidity is lower than the limit value, it will emit a signal, causing the electric heating rod embedded in the inner cavity of the central shaft 603 to start working, and the hot air will be dissipated outward through the ventilation slots 606, drying the moisture on the surface of the rotor 607. Thus, the service life of the rotor 607 can be effectively extended, and at the same time, it can effectively prevent the situation where the moisture on the surface of the rotor 607 increases the overall weight and affects flight.

[0032] In a preferred embodiment, a GPS tracker and a humidity sensor are installed in the inner cavity of the body 1, and both the motor 5 and the installer 7 are electrically connected to the remote control terminal;

[0033] Using the above structure and the characteristic that a GPS tracker is installed in the inner cavity of the body 1, in the case of loss during pesticide spraying, the device can be located according to the GPS tracker, facilitating the finding of the device and avoiding loss.

[0034] Working principle: When using this device, place the pesticide to be sprayed on the inner wall of the body 1. Through the remote terminal control and the settings of the gyroscope 9 and the accelerometer 10, the device can achieve automatic flight and pesticide spraying. During the spraying process, by transmitting a signal through the remote control terminal, the motor 5 can be started, so that the connecting rod 601 can be driven to rotate, enabling the rotor 607 to blow the pesticide during pesticide spraying, making the pesticide spraying more uniform. At the same time, when the humidity sensor detects that the humidity is lower than the limit value, it will emit a signal, causing the electric heating rod embedded in the inner cavity of the central shaft 603 to start working, and the hot air will be dissipated outward through the ventilation slots 606, drying the moisture on the surface of the rotor 607. After the pesticide spraying work is completed, the distance from the ground can be detected by the distance sensor 3, causing the distance sensor 3 to emit a signal, starting the small motor 201, driving the rotating shaft 202 to rotate, enabling the bracket 204 to drive the support leg 205 to rotate outward, slowly increasing the angle between the two support legs 205, thereby lowering the overall device, and the shock pad 206 can play a buffering role when contacting the ground, making the device convenient for the next pesticide spraying work.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
