Description

Technical Field

[0001] The present application relates to the technical field of tree root mapping, for example, to a forestry tree growth density mapping device. Background Art

[0002] Related technology (Announcement No.: CN221801393U) discloses a tree growth density measurement structure for forestry use, including a mounting frame and a clamping assembly. A frame for placing a data collector is provided on the top of the mounting frame. The clamping assembly includes transverse splints slidably arranged on both sides of the interior of the frame, and longitudinal splints are provided on the opposite sides of the two transverse splints. The transverse splints and the longitudinal splints clamp the data collector in the frame. A pull rod is provided on one side of the transverse splint, and the end of the pull rod away from the transverse splint passes through the frame and is provided with a pull plate. A clamping spring 1 is provided between the inner wall of the frame and one side of the transverse splint and is sleeved on the outside of the pull rod. Two symmetrically distributed through slots are provided on the transverse splint, and a slide is slidably provided in the through slots. The longitudinal splint is provided on one side of the slide. A cross bar is provided in the through slot that passes through the slide and slides with it. A clamping spring 2 is provided between the slide and the inner wall of the through slot and is sleeved on the outside of the cross bar.

[0003] In the process of implementing the above embodiments, it was found that there are at least the following problems in the related art:

[0004] In this tree growth density measurement structure for forestry, the horizontal clamps on both sides tend to move toward each other under the elastic force of clamping springs 1 on both sides. Under the elastic force of clamping springs 2 on both sides, the longitudinal clamps on both sides tend to move toward each other, thereby clamping and fixing the four sides of the data collector. However, during the installation or removal of the data collector, the elastic force of clamping springs 1 and 2 must be overcome, making the operation relatively laborious. Furthermore, because the springs deform when subjected to external forces, it is difficult to effectively fix the data collector using only clamping springs 1 and 2.

[0036] Combine Figures 1 to 4As shown, an embodiment of the present disclosure provides a forestry tree growth density mapping device, comprising a C-shaped plate 1, a rectangular plate 2, guide shafts 3, guide cylinders 4, a shock absorber 5, a first hanging ring 6, a chain 7, a hook 8, and track wheels. The C-shaped plate 1 includes a first through-hole located at the center of its bottom wall. The first through-hole is used to pass the detection radar of a tree radar to prevent obstruction that affects the measurement effect. The rectangular plate 2 is located above the C-shaped plate 1 along the height direction of the C-shaped plate. The rectangular plate 2 includes a second through-hole opposite the first through-hole. The second through-hole is used to pass the tree radar body to facilitate installation of the tree radar in the device. The guide shafts 3 are evenly mounted on the bottom surface of the rectangular plate 2 along the height direction of the C-shaped plate. The guide cylinders 4 are slidably mounted on the multiple guide shafts 3 and are each mounted on the bottom wall of the C-shaped plate 1. The multiple guide shafts 3 and the multiple guide cylinders 4 serve as guide supports to enable the rectangular plate 2 to move along the height direction of the C-shaped plate. Shock absorbers 5 are rotatably mounted between the rectangular plate 2 and the bottom wall of the C-shaped plate 1 along the height of the C-shaped plate. Multiple shock absorbers 5 serve as guide supports. First hanging rings 6 are mounted at the four corners of the bottom surface of the rectangular plate 2 and are used to support the mounting chains 7. Chains 7 are connected to the first hanging rings 6 at the four corners and are used to support the mounting hooks 8. Hooks 8 are connected to the chains 7 at the four corners. The hooks 8 at the four corners are used to suspend the tree radar at the four corners to assemble the tree radar into the device. Track wheels are mounted on the opposite side walls of the C-shaped plate 1. Both track wheels are used to contact the ground to drive the device to move.

[0037] The disclosed embodiment provides a forestry tree growth density mapping device. Through the design of the chains 7 at the four corners, the position adjustment range of the hooks 8 at the four corners can be increased, thereby facilitating the hanging of the hooks 8 at the four corners on the four corners of the tree radar to complete the installation of the tree radar. The tree radar can move along with the movement of the device, thereby completing the tree root density detection work. After the detection is completed, the hooks 8 at the four corners can be opened to disassemble the tree radar. Therefore, it has the advantages of stable connection and easy assembly and disassembly. During the movement of the device, multiple shock absorbers 5 can play a role in buffering and shock absorption, thereby reducing the impact and vibration of the tree radar. In addition, the method of using crawler wheels on both sides to drive the device to move is more suitable for complex terrain. When driving on soft or uneven ground, it maintains stability and easily overcomes obstacles.

[0038] Optionally, the tree radar comprises a TRU tree radar, which comprises second hanging rings at four corners of its top surface, and the hooks 8 at the four corners are respectively hung on the second hanging rings at the four corners.

[0039] In the disclosed embodiment, the tree radar adopts the design of the TRU tree radar. Its 400 MHz radar antenna can scan up to 3 meters above the ground and identify roots larger than 20 mm in diameter. Furthermore, since the TRU tree radar has secondary hanging loops at the four corners of its top surface, hooks 8 can be easily attached and removed from the corners, further facilitating assembly and disassembly of the tree radar.

[0040] Optionally, combined Figure 2 and Figure 3 As shown, the track wheel includes a driving wheel 9, a driven wheel 10, and a crawler track 11. The driving wheel 9 is rotatably mounted on opposite sides of the C-shaped plate 1, and can rotate relative to the opposite side walls of the C-shaped plate 1. The driven wheels 10 are rotatably mounted on opposite sides of the C-shaped plate 1, and are located behind the driving wheel 9 on both sides. They can rotate relative to the opposite side walls of the C-shaped plate 1. The crawler track 11 is respectively mounted on the driving wheel 9 and the driven wheel 10 on the same side, and is used to contact the ground.

[0041] In the embodiment disclosed herein, the driving wheel 9 and the driven wheel 10 on the same side are used to support and install the crawler 11, so that the crawler 11 maintains a specific shape. During use, the device is pushed and the crawler 11 can rotate along a specific track, thereby realizing the movement function.

[0042] Optionally, combined Figure 1 and Figure 4 As shown, the track wheel also includes a speed reducer 12 and a motor 13. The speed reducers 12 are mounted on opposite sides of the profile plate 1, each for reducing rotational speed and supporting the mounting of the driving wheels 9. The driving wheels 9 are mounted on the output ends of the speed reducers 12. The motors 13 are mounted on the input ends of the speed reducers 12, each for providing driving force to achieve the rotational motion.

[0043] In the disclosed embodiment, the motors 13 on both sides are controlled to rotate the driving wheels 9 via the reducers 12 on both sides. Supported by the driven wheels 10 on both sides, the tracks 11 on both sides automatically rotate along a specific trajectory, thereby achieving the device's automatic movement function. Furthermore, by controlling the motors 13 on both sides separately, the tracks 11 can rotate independently, thereby achieving a turning function. This allows the device to automatically travel around trees, thereby completing the root detection task around the tree.

[0044] Optionally, combined Figures 1 to 4As shown, the track wheel also includes seat bearings 14 and a rotating shaft 15. The seat bearings 14 are mounted on opposite sides of the C-shaped plate 1. Both seat bearings 14 are located behind the reducers 12 on either side and are used to support and mount the rotating shafts 15. The rotating shafts 15, mounted within the seat bearings 14, can rotate relative to the opposite sides of the C-shaped plate 1. The driven wheels 10, mounted on the rotating shafts 15, are free to rotate.

[0045] In the disclosed embodiment, the design of the seated bearings 14 and the rotating shafts 15 on both sides enables the driven wheels 10 on both sides to rotate relative to the opposite side walls of the profile plate 1. This can reduce the friction on the driven wheels 10 on both sides and improve the rotation accuracy of the driven wheels 10 on both sides.

[0046] Optionally, combined Figures 1 to 4 As shown, it further includes linear bearings 16. The linear bearings 16 are slidably mounted on the plurality of guide shafts 3 and are respectively installed on the top ends of the plurality of guide cylinders 4.

[0047] In the disclosed embodiment, linear bearings 16 are further included, each slidably mounted on the plurality of guide shafts 3 and mounted on the top of the plurality of guide cylinders 4.

[0048] Optionally, combined Figure 2 As shown, it further includes a limiting ring 17. The limiting ring 17 is respectively installed at the bottom ends of the multiple guide shafts 3 and is respectively located inside the multiple guide cylinders 4.

[0049] In the embodiment of the present disclosure, it also includes a limiting ring 17 respectively installed at the bottom end of the multiple guide shafts 3 and respectively located inside the multiple guide cylinders 4. The multiple limiting rings 17 are all used to limit the position to prevent the multiple guide shafts 3 and thus the multiple guide cylinders 4 from sliding out.

[0050] Optionally, combined Figures 1 to 4 As shown, the first support 18 is further included. The first support 18 is rotatably mounted on the bottom ends of the plurality of shock absorbers 5 and is mounted on the bottom wall of the U-shaped plate 1.

[0051] In the disclosed embodiment, further included are first supports 18 rotatably mounted to the bottom ends of the plurality of shock absorbers 5 and to the bottom wall of the U-shaped plate 1. The plurality of first supports 18 are used to allow the plurality of shock absorbers 5 to rotate relative to the bottom wall of the U-shaped plate 1, thereby eliminating installation errors and ensuring smooth operation of the plurality of shock absorbers 5.

[0052] Optionally, combined Figures 1 to 4As shown, the second support 19 is further included. The second supports 19 are rotatably mounted on the top ends of the plurality of shock absorbers 5 and are all mounted on the bottom surface of the rectangular plate 2.

[0053] In the disclosed embodiment, further included are second supports 19 rotatably mounted on the top ends of the plurality of shock absorbers 5 and mounted on the bottom surface of the rectangular plate 2. The plurality of second supports are used to allow the plurality of shock absorbers 5 to rotate relative to the second rectangular plate 2, thereby eliminating installation errors and ensuring smooth operation of the plurality of shock absorbers 5.
