[0033] Please see Figures 1-2 As shown, this embodiment provides a dual-rotation laser detection device, including a support base 2, a connecting cylinder 25, a transmission assembly, and a laser detection lens. The support base 2 is provided with a first motor 3, and a connecting cylinder 25 is provided on one side of the support base 2.

A second motor 5 is provided on the side of the first support plate 4 facing away from the support base 2. The output shaft of the second motor 5 is connected to the transmission assembly, and the other end of the transmission assembly is connected to the laser detection lens.

[0034] The first motor 3 can drive the first support plate 4 and other components connected to the first support plate 4 to rotate 360°. The second motor 5 can drive the transmission assembly to cause the laser detection lens to rotate. The rotation direction of the first support plate 4 is perpendicular to the rotation direction of the laser detection lens. When used for farmland management detection, a column is usually erected in the center of a large farmland, and the dual-rotation laser detection device is installed on the upper part or top of the column. A mounting base can usually be used for installation. The support base 2 can be fixed to the mounting base, which is then fixed to the column. The specific structure of the mounting base can use existing technology and will not be elaborated further. The laser detection lens rotates bidirectionally, thus avoiding blind spots within the detection range and enabling comprehensive and accurate detection.

[0035] The laser detection lens features high precision, high sensitivity, and strong anti-interference capabilities.

[0036] Furthermore, it also includes a rear cover 1 and an outer cover 12. The rear cover 1 is fixedly sleeved outside the support base 2. One end of the outer cover 12 is connected to the connecting cylinder 25, and the other end has an end hole. The side of the outer cover 12 also has a side groove communicating with the end hole. Driven by the second motor 5, the laser detection lens can rotate 90° inside the outer cover 12. When the laser detection lens is inside the outer cover 12, it can detect the farmland through the end hole. When the laser detection lens rotates, it can pass through the side groove to detect the farmland. Specifically, the outer cover 12 is snapped onto the outside of the connecting cylinder 25. When the first support plate 4 rotates, the outer cover 12 can be rotated through the connecting cylinder 25.

[0037] In some embodiments, please refer to Figures 2-4 As shown, the transmission assembly includes a support member 6, a worm gear 9, a support shaft 10, and a semi-worm wheel 13. One end of the worm gear 9 is connected to the output shaft of the second motor 5 via a first coupling 8. The support shaft 10 is mounted on the support member 6, and the semi-worm wheel 13, which meshes with the worm gear 9, is installed on the support shaft 10. The semi-worm wheel 13 is fixedly connected to the laser detection lens. The support member 6 is fixed to the inner wall of the outer cover 12. The second motor 5 drives the worm gear 9, and the semi-worm wheel 13, which meshes with the worm gear 9, causes the laser detection lens to rotate around the support shaft 10, so that the laser detection lens has a larger detection range.

[0038] Preferably, the support shaft 10 is further provided with two sets of locking members 7. The two sets of locking members 7 are located on both sides of the semi-worm gear 13 and abut against the semi-worm gear 13. The locking members 7 limit the semi-worm gear 13 and prevent it from moving on the support shaft 10 during operation, thus affecting the meshing transmission with the worm 9. Specifically, each set of locking members 7 includes two opposing arc-shaped parts fastened together with bolts. The inner wall surface of the arc-shaped parts is adapted to the outer surface of the support shaft 10. Figures 1-3 The curved components are shown, but only one curved component is shown on each side, and the bolts used to fasten the two curved components together are not shown. The bolts used to fasten the two curved components are located on both sides of the support shaft 10.

[0039] Preferably, the support member 6 is arc-shaped, and mounting holes 61 are provided at both ends of the support member 6. The two ends of the support shaft 10 are respectively assembled into the two mounting holes 61. In order to prevent the support shaft 10 from rotating in the mounting holes 61, screw holes 62 are also provided at both ends of the support member 6. The screw holes 62 are connected to the mounting holes 61 on the corresponding side. A screw is screwed into the screw hole 62, and the end of the screw enters the mounting hole 61 and abuts against the support shaft 10.

[0040] The support component 6 adopts an arc shape, which provides a large support span in a limited space, effectively utilizes space, distributes the force evenly, and absorbs and buffers some energy through the slight elastic deformation of its own arc structure, thereby reducing the impact and damage of external forces on the structure and improving its service life.

[0041] Preferably, a bearing 11 is mounted on the support shaft 10, and a semi-worm gear 13 is mounted on the outside of the bearing 11. Wear can be reduced by the bearing 11.

[0042] In some embodiments, please refer to Figures 1-2 As shown, the laser detection lens includes a first lens 14, a second lens 16, and a lens barrel 15. A lens cover 19 is fixedly connected to one end of the second lens 16, and the lens cover 19 is fixedly connected to a semi-worm gear 13. A lens barrel 15 is provided at the other end of the second lens 16, and the first lens 14 is assembled inside the lens barrel 15. A driving assembly is fixedly attached to the outside of the second lens 16. The first lens 14 is fixedly connected to the driving assembly, which can drive the first lens 14 to move closer to or further away from the second lens 16, thereby adjusting the lens focal length. The laser detection lens also includes various functional components for laser detection, such as a laser, a detector, and an RFID smart control terminal. The structure, connection relationship, and functional principle of each functional component are existing technologies. For example, a laser is disposed on the side of the lens cover 19 near the second lens 16. The laser emitted by the laser passes through the second lens 16 and the first lens 14 to illuminate the object being detected, and is reflected to the detector. The received laser signal is converted into an electrical signal or other detectable signal and sent to the RFID smart control terminal, thereby detecting the actual situation of the farmland.

[0043] Preferably, please refer to Figure 2 As shown, a lens barrel 15 is provided on the side of the second lens 16 near the first lens 14. One end of the lens barrel 15 is snapped onto the housing of the second lens 16, and the first lens 14 is assembled onto the other end of the lens barrel 15 and located inside the lens barrel 15. Exemplarily, the housing of the second lens 16 near the first lens 14 has a first-level step for engaging the lens barrel 15, and a second-level step for slidingly connecting the first lens 14. The third motor 22 drives the first lens 14 to move closer to or away from the second lens 16. Both the second-level step of the second lens 16 and the lens barrel 15 provide support and guidance for the first lens 14.

[0044] In some embodiments, please refer to Figure 7As shown, the driving assembly includes a slider support 17, a lead screw slider 18, a lead screw 20, a third motor 22, and a second support plate 23. The second support plate 23 is fixedly connected to the second lens 16. The third motor 22 is embedded in the second support plate 23. The output shaft of the third motor 22 is connected to the lead screw 20 through a second coupling 21. The lead screw slider 18 is mounted on the lead screw 20 and is fixedly connected to the slider support 17. The slider support 17 is fixedly connected to the first lens 14. The second support plate 23 is fixedly connected to the outer wall of the second lens 16, and the slider support 17 is fixedly connected to the outer wall of the first lens 14. The third motor 22 drives the lead screw 20 to rotate, and the lead screw slider 18, which meshes with the lead screw 20, performs a translational movement. Through the slider support 17, the first lens 14 is moved closer to or further away from the second lens 16, thereby adjusting the lens focal length. By adjusting the focal length, the laser reflected back from objects at different distances can form a clear image on the detector, enhancing the reflection effect of the laser by the object and thus improving the sensitivity and accuracy of the detection, improving the imaging quality and detection performance, and adapting to the target detection needs at various distances.

[0045] Preferably, a protective plate 24 is provided on the outside of the second support plate 23 to protect the drive assembly.

[0046] In some embodiments, please refer to Figure 5 As shown, the support base 2 has a plurality of ball-head plungers 28 on the end face near the first support plate 4. The ball-head plungers 28 are evenly distributed in a ring on the outer end face of the support base 2, and the first support plate 4 is in contact with the spherical surfaces of the ball-head plungers 28. The first motor 3 drives the first support plate 4 to rotate on the ball-head plungers 28, and the ball-head plungers 28 provide uniform support to the first support plate 4, which helps to reduce the wear of the first support plate 4.

[0047] In some embodiments, please refer to Figure 6 As shown, the first support plate 4 has a cross groove 41 on one side surface for mounting the second motor 5. A pressure block 26 is embedded in the cross groove 41, and the output shaft of the first motor 3 is fixedly connected to the pressure block 26. Preferably, an assembly hole is provided in the center of the pressure block 26, and the output shaft of the first motor 3 is assembled in the assembly hole. Threaded holes are provided on both sides of the pressure block 26 and at the end of the output shaft of the first motor 3. The threaded holes of the pressure block 26 and the first motor 3 correspond. After the bolt passes through the pressure block 26 and the output shaft of the first motor 3, the nut is tightened to fix the output shaft of the first motor 3 to the pressure block 26. The output shaft of the first motor 3 can transmit rotational motion to the pressure block 26, thereby driving the first support plate 4 to rotate.

[0048] Preferably, please refer to Figure 3As shown, the first support plate 4 has two screw holes on one side of its surface where the second motor 5 is mounted. These two screw holes are located on either side of the cross groove 41. The second motor 5 has lugs on both sides, each corresponding to one of the screw holes. A guide pin 27 is provided between the lugs and the screw holes. Screws pass through the lugs and are screwed into the screw holes via the guide pin 27. The guide pin 27 securely fixes the second motor 5 to the first support plate 4, preventing it from shifting during rotation with the first support plate 4. This ensures the stability of the worm gear 9, allowing it to mesh stably with the semi-worm wheel 13 for motion transmission.

[0049] This dual-rotation laser detection device, driven by a first motor 3, allows the laser detection lens to rotate 360° on a first plane and 90° on a second plane. Adjusting the pitch angle, the first and second planes are perpendicular, expanding the detection field of view and eliminating dead spots within the detection range. Driven by a third motor 22, the distance between the first and second lenses can be adjusted, thus changing the focal length of the laser detection lens. By adjusting the focal length, laser light reflected from objects at different distances can form a clear image on the detector, enhancing the reflection effect of the laser light from the object and improving detection sensitivity and accuracy, image quality, and detection performance, adapting to target detection needs at various distances.

[0050] The first motor 3, the second motor 5, the third motor 22, and the laser detection lens are all connected to a power source. To facilitate the display of detection results and control of the detection position, a display and control module associated with an RFID smart control terminal is also provided. Both the display and control module and the RFID smart control terminal can send and receive RFID wireless signals. The first motor 3, the second motor 5, and the third motor 22 are all associated with the RFID smart control terminal. Through the display and control module, commands can be sent to the RFID smart control terminal to control the start, stop, and speed of the first motor 3, the second motor 5, and the third motor 22, and to adjust the viewing angle of the laser detection lens. The RFID smart control terminal transmits the farmland information collected by the laser detection lens to the display and control module for viewing the farmland conditions. The viewing angle of the laser detection lens can also be adjusted through the display and control module to achieve fixed-point viewing. Control parameters and sampling frequencies can also be preset in the display and control module, enabling the detection device to automatically cruise and sample, and then transmit the sampling information back to the display and control module for personnel to view. The display and control module can be carried by a computer and / or a mobile phone. The signal transmission, command operation, and information storage and retrieval of the display and control module and RFID intelligent control terminal are based on existing technologies and are not key areas for improvement, so they will not be elaborated here.
