[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] According to the forestry pest monitoring drone of the embodiment of the present invention, Figure 1 and Figure 2As shown, the drone body 10, the camera 20, the main control unit 30, the positioning unit 40 and the spray paint marking device 50 are included; the camera 20 is arranged on the drone body 10, and the camera 20 is used to photograph the trees in the forest area during the flight of the drone body 10; the main control unit 30 and the positioning unit 40 are both arranged in the drone body 10, the main control unit 30 is connected with the camera 20 and the terminal control device 70, and the main control unit 30 is used to transmit the image data photographed by the camera 20 back to the terminal control device 70 to determine whether the trees in the forest area are infected with pests and diseases, and when it is determined that the trees are infected with pests and diseases, the drone body 10 is controlled to fly to a distance less than the expected distance from the trees infected with pests and diseases according to the instructions of the terminal control device 70. The positioning unit 40 is connected to the main control unit 30. The positioning unit 40 is used to locate the trees with pests and diseases according to the instructions of the terminal control device 70 when the drone body 10 flies to a position less than the preset distance from the trees with pests and diseases, and transmit the positioning position back to the terminal control device 70 through the main control unit 30 to mark the position of the trees with pests and diseases once; the spray paint marking device 50 is set on the drone body 10 and connected to the main control unit 30. The spray paint marking device 50 is used to spray paint on the trees with pests and diseases according to the instructions of the terminal control device 70 when the drone body 10 flies to a position less than the preset distance from the trees with pests and diseases, so as to mark the position of the trees with pests and diseases twice. Therefore, when the trees with pests and diseases are monitored, the approximate position of the trees with pests and diseases can be marked by the positioning unit 40, and the trees with pests and diseases can be accurately marked by the spray paint marking device 50 to form an obvious mark, so that when the trees with pests and diseases are prevented and treated in the later stage, the trees with pests and diseases can be found conveniently and quickly. The invention solves the problem that when pest and disease monitoring drones in the prior art detect trees with pests and diseases, the efficiency of manually marking the trees with pests and diseases is low.

[0025] In specific implementation, a communication module is provided inside the main control unit 30, and the main control unit 30 communicates with the terminal control device 70 through the communication module; the terminal control device 70 is a handheld drone controller that can display the shooting picture of the camera 20 in real time. Figure 1 and Figure 2As shown, the paint marking device 50 includes a paint storage box 51, a connecting pipe 52, a nozzle 53 and an electric pump 54. The paint storage box 51 is arranged below the UAV body 10, and the paint storage box 51 is used to store paint; one end of the connecting pipe 52 is connected to the inner cavity of the paint storage box 51; the nozzle 53 is arranged in front of the UAV body 10, and the other end of the connecting pipe 52 is connected to the nozzle 53; the electric pump 54 is arranged on the connecting pipe 52 and connected to the main control unit 30; optionally, the paint spraying direction of the nozzle 53 is the same as the shooting direction of the camera 20. When the drone body 10 flies to a position less than a preset distance from the tree where the pest occurs, the operator determines the location of the tree pest according to the shooting picture sent back in real time by the main control unit 30 to the terminal control device 70. After determining the marking position, the electric pump 54 is remotely started through the terminal control device 70. The electric pump 54 is started according to the instruction of the terminal control device 70 to transport the paint in the paint storage box 51 to the nozzle 53 through the connecting pipe 52 so as to spray it on the tree where the pest occurs for marking. The color of the paint needs to be selected with a large contrast with the branches and leaves of the tree, so as to facilitate later identification.

[0026] In addition, in order to facilitate the collection of leaves from trees with pests and diseases for subsequent pathological experiments and to determine the pest and disease situation, the forest pest and disease monitoring drone further includes a leaf collection device 60, which is disposed on the drone body 10 and connected to the main control unit 30. The leaf collection device 60 is used to collect leaf samples from trees with pests and diseases according to the instructions of the terminal control device 70.

[0027] Specifically, Figure 1 As shown, the leaf collecting device 60 includes a shearing mechanism 61 and a storage mechanism 62. The shearing mechanism 61 is used to cut leaf samples from trees with pests and diseases; the storage mechanism 62 is arranged corresponding to the shearing mechanism 61, and the storage mechanism 62 is used to receive and store the leaf samples cut by the shearing mechanism 61.

[0028] Furthermore, if Figure 1 and Figure 3As shown, the leaf collecting device 60 also includes a box body 63, the inner cavity of the box body 63 is divided into an upper accommodating chamber and a lower accommodating chamber by a partition 64, and the shearing mechanism 61 includes a shearing knife 611, a driving arm 612, an electric telescopic rod 613, a sliding pin 614, a connecting block 615 and a sliding stabilizing rod 616; the top wall and the bottom surface of the front end opening of the upper accommodating chamber are provided with a first sliding groove 65 opposite to each other, and the first sliding groove 65 extends along the width direction of the upper accommodating chamber; there are two shearing knives 611, and the rear ends of the two shearing knives 611 are both provided with a sliding pin 614 matching the first sliding groove 65, and the sliding pin 614 is provided to the connecting block 615. The pin 614 passes through the rear end of the shearing knife 611 along the thickness direction of the shearing knife 611 and is fixedly connected. The two ends of the sliding pin 614 are correspondingly slidably embedded in the two first sliding grooves 65 at the front end opening of the upper accommodating chamber so that the two shearing knives 611 can slide relatively along the width direction of the upper accommodating chamber; there are two driving arms 612, and the first ends of the two driving arms 612 are correspondingly hinged to the rear ends of the two shearing knives 611; the connecting block 615 is fixedly arranged at the end of the piston rod of the electric telescopic rod 613, and the end of the piston rod of the electric telescopic rod 613 is connected to the two driving arms 613 through the connecting block 615. The second ends of 12 are hinged to each other, and the end of the cylinder body of the electric telescopic rod 613 is fixedly connected to the rear end wall of the upper accommodating chamber; the two opposite side walls of the upper accommodating chamber are respectively provided with second slide grooves 66, and the second slide grooves 66 extend along the telescopic direction of the piston rod of the electric telescopic rod 613; the sliding stabilizing rod 616 passes through the connecting block 615 in the transverse direction and is fixedly connected to the connecting block 615, and the two ends of the sliding stabilizing rod 616 can be slidably embedded in the two second slide grooves 66; the electric telescopic rod 613 is connected to the main control unit 30, and when leaf samples need to be collected, the operator terminal control device 70 controls the unmanned The position and angle of the machine body 10 control the position and angle of the two shearing knives 611. The two shearing knives 611 are located above the camera 20. The angle and position between the two shearing knives 611 and the leaves can be observed in real time through the images sent back by the camera 20. When the leaves are located between the two shearing knives 611, an action instruction is sent to the electric telescopic rod 613 through the terminal control device 70. The piston rod of the electric telescopic rod 613 retracts backwards, thereby driving the two shearing knives 611 to move closer to each other and close to each other through the two driving arms 612, thereby cutting off the leaf samples of the trees with pests and diseases. Optionally, the shear knife 611 includes a handle, a connecting plate and a blade, and a sliding pin 614 is arranged on the handle of the shear knife 611. The handles of the two shear knives 611 are slidably embedded in the two first sliding grooves 65 at the front end opening of the upper accommodating cavity through the sliding pin 614 so that the two shear knives 611 can slide relative to each other along the width direction of the upper accommodating cavity; one end of the connecting plate is fixedly connected to the handle, and the other end of the connecting plate is a free end, and the blade is fixedly mounted on the connecting plate. The electric telescopic rod 613 drives the two shear knives 611 to move closer to each other and cut off the leaf samples of the trees with pests and diseases through the two blades.

[0029] Since the telescopic movement stroke of the electric telescopic rod 613 is relatively large, the sliding stabilizing rod 616 moves synchronously with the piston rod of the electric telescopic rod 613 during this process to stabilize and support the piston rod of the electric telescopic rod 613, thereby making the movement of the two shearing knives 611 smoother.

[0030] like Figure 1 and Figure 4 The storage mechanism 62 shown includes a collecting box 621, a fixed pulley 622 and a pull rope 623. The collecting box 621 is slidably arranged in the lower accommodating chamber along the extension and retraction direction of the piston rod of the electric telescopic rod 613 so as to extend from the lower accommodating chamber or retract into the lower accommodating chamber; when the collecting box 621 is extended from the lower accommodating chamber, it is located below the two shearing knives 611, and the leaf samples cut by the two shearing knives 611 fall into the collecting box for storage.

[0031] Specifically, the partition 64 is provided with an opening that connects the upper accommodating chamber and the lower accommodating chamber, the fixed pulley 622 is installed at the opening, one end of the pull rope 623 is connected to the connecting block 615, and the other end of the pull rope 623 passes around the fixed pulley 622 and is connected to the rear end of the collecting box 621; when the piston rod of the electric telescopic rod 613 retracts, it drives the two shear knives 611 to close to each other to cut off the leaf samples of the trees with diseases and insect pests, and at the same time, the collecting box 621 is synchronously driven to extend from the lower accommodating chamber through the pull rope 623, and the extended collecting box 621 just catches the cut leaf samples.

[0032] Furthermore, the storage mechanism 62 also includes a spring 624, which is arranged at the rear end of the lower accommodating chamber, one end of the spring 624 is connected to the rear end wall of the lower accommodating chamber, and the other end of the spring 624 is connected to the rear end of the collecting box 621; the electric telescopic rod 613 stretches the spring 624 during the process of driving the collecting box 621 to extend from the lower accommodating chamber; after the leaf sample is cut off, the piston rod of the electric telescopic rod 613 extends to drive the two shear knives 611 to separate from each other. At this time, the pull rope 623 loses the pulling force, and the collecting box 621 automatically returns to the lower accommodating chamber under the elastic force of the spring 624 to store the collected leaf samples, thereby preventing the collected leaf samples from being scattered during the flight of the drone body 10.

[0033] Furthermore, if Figure 1 As shown, the forestry pest monitoring drone according to the embodiment of the present invention further includes a rotor 80 and a connecting arm 90, and the rotor 80 and the connecting arm 90 are both multiple, and the multiple rotors 80 are correspondingly connected to the drone body 10 through the multiple connecting arms 90. Optionally, the connecting arm 90 includes a first connecting arm 91 and a second connecting arm 92, and the first connecting arm 91 and the second connecting arm 92 are connected to each other through a damping shaft so that they can rotate within a certain range to adjust the angle of the rotor 80.

[0034] Furthermore, the forestry pest monitoring drone of the embodiment of the present invention further includes a solar panel 100, which can utilize solar energy to charge a battery disposed in the drone body 10, thereby increasing the cruising range of the drone.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
