[0027] The adjusting mechanism 8 is arranged on the top surface of the working plate 1 and is used to adjust the height and angle of the 3D scanner 7. The adjusting mechanism 8 includes an L-shaped vertical plate 81 fixed on the top surface of the working plate 1, a rotating rod 82 rotatably connected between the horizontal plate end of the vertical plate 81 and the working plate 1, two rollers 84 rotatably connected to the top surface of the working plate 1 and respectively located on the front and rear sides of the rotating rod 82, two rotating columns 86 rotatably connected to the horizontal plate end of the vertical plate 81, a lifting motor 810 installed on the bottom surface of the working plate 1 and with the output shaft coaxially connected to the rotating rod 82, two driven gears 85 coaxially fixed on the circumferential outer wall of the rotating roller 84 on the same side, a driving gear 83 coaxially fixed on the circumferential outer wall of the rotating rod 82 and meshing with the two driven gears 85, a screw 87 coaxially fixed between the rotating column 86 and the rotating roller 84 on the same side, the adjusting mechanism 8 also includes two moving rods 88 respectively threadedly connected to the screw 87 on the same side and slidably connected to the vertical plate end of the vertical plate 81, a lifting motor 810 fixed on the bottom surface of the working plate 1 and with the output shaft coaxially connected to the rotating rod 82 The mounting plate 812 on the left surface of the two moving rods 88, the turntable 813 located directly above the mounting plate 812, the rotating shaft 814 coaxially fixed on the bottom surface of the turntable 813 and rotatably connected to the mounting plate 812, the rotating motor 815 installed on the bottom surface of the mounting plate 812 and the output shaft coaxially connected to the rotating shaft 814, and the 3D scanner 7 installed on the top surface of the turntable 813. By setting the working plate 1, several support columns 2, several support plates 3, several universal wheels 4 and the 3D scanner 7, the crown width of the tree can be measured. By setting the adjustment mechanism 8, the height and angle of the 3D scanner 7 can be adjusted, so that the measurement range of the entire 3D scanner 7 is wider, and the measurement of the entire device is more accurate. There is no need to manually move the position of the 3D scanner 7 frequently to measure the crown width of the tree, which saves time and effort. It should be added that the universal wheel 4 is a prior art and has a built-in locking structure.

[0028] In this embodiment, the adjustment mechanism 8 also includes a protective box 811 fixed on the bottom surface of the working plate 1 and a motor box 816 fixed on the bottom surface of the mounting plate 812. The lifting motor 810 is located inside the protective box 811, and the rotating motor 815 is located inside the motor box 816, which can protect the lifting motor 810 and the rotating motor 815, thereby extending the service life of the lifting motor 810 and the rotating motor 815.

[0029] In addition, two vertically arranged guide grooves are provided on the left side surface of the vertical plate end of the vertical plate 81, and a guide block 89 is fixed on the right side surface of the moving rod 88, which is slidably connected to the guide groove on the same side of the left side surface of the vertical plate end of the vertical plate 81. It can guide the movement of the two moving rods 88, and then indirectly guide the movement of the mounting plate 812, the turntable 813 and the 3D scanner 7.

[0030] Furthermore, an L-shaped push-pull rod 5 is fixed to the front and rear surfaces of the working plate 1, and a handle 6 is fixed to the right surface of the cross bar end of the push-pull rod 5. The staff can drive the entire device to move by holding the two handles 6 and using several universal wheels 4.

[0031] Specifically, the distance between the driving gear 83 and the vertical plate end of the vertical plate 81 is 3-11 cm, the distance between the driving gear 83 and the working plate 1 is 4-12 cm, the distance between the two driven gears 85 and the vertical plate end of the vertical plate 81 is 4-10 cm, and the distance between the two driven gears 85 and the working plate 1 is 3-11 cm. In this article, the distance between the driving gear 83 and the vertical plate end of the vertical plate 81 is preferably 7 cm, and the distance between the driving gear 83 and the working plate 1 is preferably 7 cm. In this article, the distance between the two driven gears 85 and the vertical plate end of the vertical plate 81 is preferably 7 cm, and the distance between the two driven gears 85 and the working plate 1 is preferably 7 cm, so that the two driven gears 85 and the driving gear 83 can be unobstructed during the rotation process.

[0032] It is worth noting that the transverse cross-sectional shape of the guide groove on the left side surface of the vertical plate end of the vertical plate 81 is convex, and the shape of the guide block 89 is convex to match the shape of the guide groove on the left side surface of the vertical plate end of the vertical plate 81, which can make the connection between the guide block 89 and the guide groove on the left side surface of the vertical plate end of the vertical plate 81 tighter, and thus indirectly make the mounting plate 812, the turntable 813 and the 3D scanner 7 more stable during the movement.

[0033] It is worth noting that the length of the handle 6 is 10-20 cm, and the outer wall of the handle 6 is provided with anti-slip grooves, which is preferably 15 cm in this article, so as to increase the friction between the handle 6 and the palm of the staff, thereby making the entire device more stable during movement.

[0034] Finally, it should be noted that the 3D scanner 7, lifting motor 810, rotating motor 815 and other components involved in the present invention are all universal standard parts or components known to technical personnel in this field. Their structures and principles are known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in this field.

[0035] During the specific use of this embodiment, when it is necessary to measure the crown width of a tree, the external computer is connected to the 3D scanner 7. The staff first holds the two handles 6 and cooperates with the two push-pull rods 5, several support columns 2, several support plates 3 and several universal wheels 4 to drive the entire device to move. After the entire device is moved to a suitable position, the locking structure in the universal wheels 4 can be used to position the entire device. Then, the lifting motor 810 is started through the external PLC. The output shaft of the lifting motor 810 rotates to drive the rotating rod 82 coaxially connected thereto to rotate. The rotation of the rotating rod 82 drives the driving gear 83 coaxially fixed thereto to rotate. The driving gear 83 rotates to drive the meshing gear 83. The two driven gears 85 rotate, and the driven gear 85 drives the coaxially fixed roller 84 on the same side to rotate, and the rotation of the roller 84 drives the coaxially fixed screw 87 on the same side to rotate, and the rotation of the screw 87 drives the moving rod 88 threadedly connected to it to move, and the moving rod 88 moves under the guidance of the guide block 89 on the same side and the guide groove on the left side of the vertical plate end of the vertical plate 81. The movement of the two moving rods 88 drives the mounting plate 812 fixed thereto to move, and the movement of the mounting plate 812 drives the turntable 813, the rotating shaft 814, the rotating motor 815, and the 3D scanner 7 to move in the vertical direction. When the 3D scanner 7 moves to a suitable height position, the lifting motor 810 is turned off by the external PLC;

[0036] Then, the rotating motor 815 is started through the external PLC. The output shaft of the rotating motor 815 rotates, driving the rotating shaft 814 coaxially connected thereto. The rotation of the rotating shaft 814 drives the coaxially fixed turntable 813 to rotate. The rotation of the turntable 813 drives the 3D scanner 7 fixed thereto to rotate. When the test end of the 3D scanner 7 rotates to a suitable angle position, the rotating motor 815 is turned off through the external PLC. The startup program in the external computer starts the 3D scanner 7 so that the crown width of the tree can be measured.

[0037] After the data at that position are measured, the entire device can be moved to different positions near the tree as described above, and the height and angle of the 3D scanner 7 can be adjusted by the adjustment mechanism 8. The 3D scanner 7 can be driven by an external computer to perform scanning operations, thereby accurately measuring the crown width of the tree.
