[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 , an intelligent dosing device for a plant protection drone, comprising an equipment box 1, a drone body 2 is arranged outside the equipment box 1, a control panel 3 is arranged on the front of the equipment box 1, a shock absorbing and buffering structure 4 is arranged inside the equipment box 1, and a dosing structure 5 is arranged inside the equipment box 1;

[0027] The shock-absorbing and buffering structure 4 includes a bottom block 401, the bottom block 401 is fixedly installed on the inner bottom wall of the equipment box 1, a spring damper 402 is fixedly installed inside the bottom block 401, a slider 403 is fixedly installed on the outer surface of the spring damper 402, a hinged rod 404 is fixedly installed on the top of the slider 403, a placement plate 405 is fixedly installed on the top of the hinged rod 404, a spring body 406 is fixedly installed on the inner bottom wall of the equipment box 1, a telescopic rod 407 is fixedly installed on the inner bottom wall of the equipment box 1, and a rubber block 408 is fixedly installed on the top of the telescopic rod 407.

[0028] Furthermore, the dosing structure 5 includes a liquid storage tank 501, the liquid storage tank 501 is fixedly installed inside the equipment box 1, the first motor 502 is fixedly installed inside the liquid storage tank 501, the stirring rod 503 is rotatably connected inside the liquid storage tank 501, the water pump 504 is fixedly installed inside the liquid storage tank 501, the second motor 505 is fixedly installed inside the placement plate 405, the threaded rod 506 is rotatably connected inside the placement plate 405, the outer surface of the threaded rod 506 is threadedly connected to the connecting plate 507, and the button 508 is fixedly installed inside the placement plate 405.

[0029] Specifically, Figure 4 As shown, when the device is not in use, the telescopic rod 407 retracts the rubber block 408. When the drone body 2 needs to perform a dosing process, it is first controlled to land on the placement plate 405, and the landing gear falls into the inside of the landing trough. At the same time, affected by the landing impact of the drone body 2, the placement plate 405 will move downward appropriately. During the movement of the placement plate 405, the vibration force will first be initially absorbed by the spring body 406. At the same time, the placement plate 405 will drive the hinged rod 404 and the slider 403 to move along the guide rod, and squeeze the spring damper 402. The vibration force and impact force are absorbed and weakened by the spring damper 402, thereby providing shock-absorbing and buffering protection for the drone body 2. Then, after the drone body 2 is in a stable state, the telescopic rod 407 is opened to drive the rubber block 408 to move upward, and the placement plate 405 is raised to the highest point to ensure the smoothness of the subsequent dosing process.

[0030] Specifically, Figure 5 As shown, turning on the first motor 502 can drive the stirring rod 503 to rotate, and the medicine inside the liquid storage chamber is evenly stirred by the rotation of the stirring rod 503, ensuring that the medicine is evenly stirred and having a better effect.

[0031] Specifically, Figure 6As shown, after stirring evenly, the second motor 505 is turned on to drive the threaded rod 506 to rotate, and the rotation of the threaded rod 506 drives the connecting plate 507 to move inside the active chamber. During the movement of the connecting plate 507, the docking tube will be connected to the one-way valve tube of the drone body 2. After the connection is completed, the connecting plate 507 will touch two buttons 508 at the same time. By touching the two buttons 508 at the same time, the water pump 504 can be turned on to extract the stirred medicine, and send it into the docking tube through the telescopic hose, and then send it into the interior of the drone body 2 through the one-way valve tube. When the drone body 2 is full, the second motor 505 is controlled to rotate in the opposite direction, thereby controlling the threaded rod 506 to rotate in the opposite direction, and driving the connecting plate 507 to move in the opposite direction, so that the docking tube and the one-way valve tube are separated, and at the same time, they are separated from the two buttons 508, thereby turning off the water pump 504, thereby achieving the purpose of facilitating the dosing process of the drone body 2.

[0032] Specifically, Figure 2 As shown, the control panel 3 is electrically connected to the powered devices in the device. The control panel 3 sends control instructions to each component through the control signal line. These signal lines can be analog signal lines such as 4-20mA current signals, digital signal lines such as RS485 communication interfaces or simple switch signal lines. The control signals sent by the control panel 3 are transmitted to the control units of each component through the signal lines. The start and stop operations of each component can be realized through the buttons or touch screen interface on the control panel 3. After receiving the start instruction, the controller will send corresponding control signals to each component to start them. When receiving the stop instruction, it will send a stop signal to stop each component. The working parameters of each component are set on the control panel 3 interface. These parameter settings will be converted into corresponding control signals and sent to the control units of each component, so as to realize precise adjustment of the working status of the component. The control panel 3 has the function of monitoring the operating status of each component and can display the working parameters and status information of each component in real time.

[0033] Specifically, Figure 6 As shown, the second motor 505 is a forward and reverse motor, which refers to a motor that can realize forward and reverse operation. The working principle of the forward and reverse motor is based on changing the phase sequence of the motor power supply to achieve a change in the rotation direction. In a three-phase asynchronous motor, the rotation direction of the motor can be changed by swapping any two phases. This operation is called commutation, which allows the motor to run in different directions as needed.

[0034] Specifically, Figure 1 As shown, the spring body 406 is a rubber spring. The rubber spring uses the elasticity and deformation ability of the rubber material to buffer impact and vibration. The rubber spring has good wear resistance and corrosion resistance, and has a good damping effect, and can effectively reduce impact and vibration.

[0035] When implementing, follow these steps:

[0036] 1) First, control the drone body 2 to land on the top of the placement board 405;

[0037] 2) Then, during the landing process, the shock-absorbing and buffering structure 4 is provided to absorb and reduce the vibration impact force generated by the landing;

[0038] 3) The drug adding structure 5 is provided to ensure that the drug is stirred evenly, and at the same time facilitate the drug adding process to the drone body 2.

[0039] To sum up, the intelligent dosing device for plant protection UAV can absorb and weaken the vibration impact caused by the landing of the UAV body 2 through the set shock-absorbing buffer structure 4, so as to provide shock-absorbing protection for the UAV body 2. After the UAV body 2 lands, the medicine solution is evenly stirred through the setting of the dosing structure 5, and the evenly stirred medicine solution is sent to the interior of the UAV body 2 for the dosing process, thereby achieving the purpose of providing shock-absorbing protection for the UAV body 2 and facilitating the dosing process.
