Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a pesticide spraying device applied to unmanned aerial vehicles. Background Art

[0002] With the rapid development of drone technology, functions such as drone sowing and drone spraying have been developed in crop planting. Compared with traditional manual spraying, drone spraying can be remotely controlled, and people will not be directly exposed to pesticides, which can protect people's health to a certain extent. At the same time, drone spraying has a wider coverage area, and the crops receive drugs more evenly, which greatly improves the growth environment of crops.

[0003] After searching, the Chinese patent number CN215302591U discloses that the utility model provides a pesticide spraying device for unmanned aerial vehicles, including a frame of an unmanned aerial vehicle, a detachable liquid storage tank is installed at the bottom of the frame, a fixing plate is fixed at the bottom of the liquid storage tank, both sides of the fixing plate are connected with connectors through a rotating shaft, a spray pipe that can rotate 180° is installed on the connector, the side wall of the spray pipe is provided with a plurality of water outlets, and a rotating mechanism that can simultaneously drive two connectors to rotate to a horizontal state or a vertical state is installed on the fixing plate, when the connector is in a horizontal state, the plurality of water outlets on the two spray pipes are vertically downward, and when the connector is in a vertical state, the plurality of water outlets on the two spray pipes face both sides. The device can greatly increase the spraying range, and can fly between ridges and spray the straw parts of crops on both sides.

[0004] However, existing drones are generally set with fixed routes to drive the spray heads to move, and the drones themselves generally do not have a camera function, which will result in the background staff being unable to timely understand the on-site pesticide spraying situation. In addition, since the drones themselves need to work outdoors for a long time, the cameras are exposed to the environment for a long time, especially in bad weather conditions, which can easily cause damage to the drones. Based on this, the utility model designs a pesticide spraying device for drones to solve the above problems. Utility Model Content

When the camera is stored, the electric push rod is started to shrink and drive the camera to move to the inside of the fixed frame. At this time, the squeezed telescopic rod and the squeezing spring return to their original state after no external force is squeezed, and cover the outside of the camera, so as to seal and protect the camera.

[0021] 2. The utility model uses the cooperation between the drone body and the camera.

[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 The orientation is used as a reference.

[0029] The technical problem of the lack of camera function proposed in the embodiment of the utility model is that when the camera 2 is moved to the outside of the fixed frame 3, it can shoot the surrounding environment. When the camera 2 is stored, the electric push rod 4 is started to shrink and drive the camera 2 to move to the inside of the fixed frame 3. At this time, the squeezed telescopic rod 6 and the squeezing spring 7 return to their original state after no external force is squeezed, and cover the outside of the camera 2, so as to seal and protect the camera 2.

[0030] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Example 1

[0031] Reference Figure 1-Figure 3 A pesticide spraying device for a drone includes a drone body 1 and a camera 2. A rotating mechanism for pesticide mixing is installed on the top of the drone body 1. A moving mechanism for retracting the camera 2 is installed on the top of the drone body 1. The moving mechanism includes a fixed frame 3. An electric push rod 4 is fixedly connected to the inner cavity of the fixed frame 3. The electric push rod 4 is fixed to the camera 2. A mounting block 5 is installed in the inner cavity of the fixed frame 3. A telescopic rod 6 is fixedly connected between the fixed frame 3 and the mounting block 5. An extrusion spring 7 is sleeved on the outer ring of the telescopic rod 6.

[0032] The fixed frame 3 is provided with two groups and is symmetrically distributed, the electric push rod 4 is provided with two groups and is symmetrically distributed, the camera 2 is provided with two groups and is symmetrically distributed, the mounting block 5 is provided with multiple groups of rectangular array distribution, the telescopic rod 6 is provided with multiple groups of rectangular array distribution, and the extrusion spring 7 is provided with multiple groups of rectangular array distribution.

[0033] In the embodiment of the utility model, during the process of pesticide spraying, the staff needs to record the spraying range of the drone body 1 at all times through the video of the camera 2. When it is necessary to enter the monitoring activity, the electric push rod 4 is started, the electric push rod 4 is extended, and the camera 2 is driven to move. Since the camera 2 is set between the mounting blocks 5, the direction of movement of the camera 2 will be limited, making the camera 2 more stable when moving. The camera 2 is a wedge-shaped structure. During the process of the camera 2 moving outward, the wider part will squeeze the mounting block 5 of the outer circle. After being squeezed, the mounting block 5 moves toward the edge, thereby squeezing the telescopic rod 6 and the squeezing spring 7, so that the squeezing spring 7 is in a compressed state during the process of the camera 2 moving outward; when the camera 2 moves to the outside of the fixed frame 3, it can shoot the surrounding environment.

[0034] When the use environment is relatively harsh and the camera 2 needs to be stored, the electric push rod 4 is started to retract and drive the camera 2 to move toward the inside of the fixed frame 3. At this time, the squeezed telescopic rod 6 and the squeezing spring 7 return to their original state after no external force is squeezed, and cover the outside of the camera 2 to seal and protect the camera 2. Example 2

[0035] Reference Figure 1-Figure 4 The rotating mechanism includes a liquid storage tank 8, a mounting seat 9 is fixedly connected to the front of the liquid storage tank 8, a servo motor 10 is fixedly connected to the inner cavity of the mounting seat 9, a rotating rod 11 is fixedly connected to the back of the output shaft of the servo motor 10, a rotating plate 12 is fixedly connected to the outer ring of the rotating rod 11, and the rotating plate 12 is provided with multiple groups of circumferential array distribution. The servo motor 10 and the rotating rod 11 are rotatably connected through a coupling, a sealing plate 13 is hinged on the top of the liquid storage tank 8, and a handle 14 is fixedly connected to the back of the sealing plate 13.

[0036] A support rod 15 is fixedly connected to the bottom of the drone body 1, a wing 16 is fixedly connected to one side of the drone body 1, a protective frame 17 is installed on the top of the wing 16, a propeller blade 18 is installed on the top of the wing 16, the support rod 15 is arranged with a plurality of groups of rectangular array distribution, the wing 16 is arranged with a plurality of groups of rectangular array distribution, the protective frame 17 is arranged with a plurality of groups of rectangular array distribution, and the propeller blade 18 is arranged with a plurality of groups of rectangular array distribution.

[0037] In the embodiment of the utility model, when the liquid inside the liquid storage tank 8 reaches the bottom, the staff controls the drone to land, and the support rod 15 can start the support function when the drone lands on the ground. When the staff matches the liquid in the liquid storage tank 8, the servo motor 10 is started, and the servo motor 10 drives the rotating rod 11 to rotate. Since the rotating plate 12 is fixedly connected to the outer ring of the rotating rod 11, starting the servo motor 10 can drive the rotating plate 12 to rotate. During the rotation of the rotating plate 12, the liquid inside the liquid storage tank 8 can be stirred evenly, thereby reducing the operating steps of the staff and improving the practicality of the device.

[0038] After the liquid inside the liquid storage tank 8 is stirred evenly, the drone body 1 is started. The drone body 1 can control the propeller blades 18 to rotate. During the rotation of the propeller blades 18, the drone body 1 can be driven to rise. The working principle of this part belongs to aerodynamics and belongs to the scope of the prior art, so it is not elaborated here; the protective frame 17 is arranged on the outer ring of the propeller blades 18, which can protect the propeller blades 18. When the drone body 1 moves to a suitable position, the nozzle at the bottom of the liquid storage tank 8 is started, and the nozzle can spray the liquid in the liquid storage tank 8 to spray the crops. In conjunction with the movement of the drone itself, the spraying position can also change. The camera 2 can transmit the captured image to the staff in the background, so that the staff can understand the spraying situation and control the directional movement of the drone and the nozzle.
