[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] First Embodiment

[0038] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The evaluation device for seedling measurement includes: a support structure 1, which includes a base 11, a load-bearing rod 12 and a transmission groove 121. The load-bearing rod 12 is fixedly installed on the base 11, and the transmission groove 121 is opened inside the load-bearing rod 12.

[0039] The drive structure 2 includes a protective shell 21, a sliding sleeve 22, and a toothed plate 25. The protective shell 21 is fixedly installed on the top of the load-bearing rod 12, the sliding sleeve 22 is slidably installed inside the protective shell 21, and the toothed plate 25 is fixedly installed on the bottom of the sliding sleeve 22.

[0040] The transmission structure 3 includes a rotating shaft 31, a transmission gear 32, a first transmission wheel 33, and a transmission belt 34. The rotating shaft 31 is rotatably mounted inside the protective shell 21. The transmission gear 32 and the first transmission wheel 33 are both fixedly mounted on the rotating shaft 31. The transmission gear 32 is meshed with the toothed plate 25. The transmission belt 34 is slidably connected to the first transmission wheel 33.

[0041] Adjustment structure 4 includes a threaded rod 41, a second transmission wheel 42, a slider 43, a pointer 44, and a first clamping plate 45. The threaded rod 41 is rotatably mounted on the load-bearing rod 12. The second transmission wheel 42 is fixedly mounted on the threaded rod 41 and is slidably connected to the transmission belt 34. The slider 43 is threadedly connected to the threaded rod 41. The pointer 44 and the first clamping plate 45 are fixedly mounted on both sides of the slider 43, respectively.

[0042] Measuring structure 5 is fixedly installed on the load-bearing rod 12;

[0043] During measurement, the surveyor places the base 11 on the ground at the base of the seedling. The distance between the measuring structure 5 and the bottom of the base 11 is set to 1.3 meters, so that the main trunk of the seedling is located between the measuring structure 5 and the first clamping plate 45, and is in close contact with the measuring structure 5. Then, the surveyor holds the protective shell 21 and presses the sliding sleeve 22. The sliding sleeve 22 drives the toothed plate 25 to move into the protective shell 21. The toothed plate 25 drives the transmission gear 32 and the rotating shaft 31 to rotate. The rotating shaft 31 drives the first transmission wheel 33 to rotate. The transmission belt 34 passes through the transmission groove 121 and is slidably connected to the first transmission wheel 33. On the second transmission wheel 42, the first transmission wheel 33 drives the second transmission wheel 42 to rotate via the transmission belt 34. The second transmission wheel 42 drives the threaded rod 41 to rotate, driving the slider 43 to slide the pointer 44 and the first clamping plate 45. When the first clamping plate 45 contacts the tree, the measuring structure 5 and the first clamping plate 45 clamp and fix the main trunk of the seedling. Then, the measuring personnel record the scale indicated by the pointer 44 on the measuring structure 5, thus achieving the purpose of measuring the diameter at breast height. This avoids the measuring personnel having to squat and stand up to perform the measurement operation, improving work efficiency and reducing the workload of the measuring personnel.

[0044] Please refer to the following: Figure 1 and Figure 2 The measuring structure 5 includes a scale plate 51 and a second clamping plate 52. The scale plate 51 is fixedly installed on the load-bearing rod 12, and the second clamping plate 52 is fixedly installed on the scale plate 51.

[0045] During measurement, the surveyor places the main trunk of the seedling close to the surface of the second clamping plate 52, presses the sliding sleeve 22 to drive the slider 43 to move the pointer 44 and the first clamping plate 45 toward the main trunk. When the first clamping plate 45 contacts the main trunk, the pressure on the sliding sleeve 22 is stopped. At this time, the scale indicated by the pointer 44 on the scale plate 51 is the diameter at breast height (DBH) of the main trunk, thus achieving the purpose of measuring the DBH.

[0046] Please refer to the following: Figure 2 and Figure 3 The driving structure 2 further includes a first limiting rod 23 and a first elastic element 24. The first limiting rod 23 is fixedly installed inside the protective shell 21, and the first elastic element 24 is fixedly installed between the protective shell 21 and the sliding sleeve 22, and is sleeved on the first limiting rod 23.

[0047] When the sliding sleeve 22 is pressed, the sliding sleeve 22 slides on the first limiting rod 23 and simultaneously compresses the first elastic element 24. The first elastic element 24 accumulates elastic potential energy. When the measurement is completed, the sliding sleeve 22 is released, and the first elastic element 24 releases its elastic potential energy, pushing the sliding sleeve 22 to move back to the initial position. At the same time, the toothed plate 25 drives the transmission gear 32 to move in the opposite direction, releasing the clamping plate 45 from the main trunk of the seedling, and simultaneously achieving the purpose of resetting the pointer 44.

[0048] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The support structure 1 also includes three fixing nails 13, which are symmetrically fixedly installed on the bottom of the base 11;

[0049] When taking measurements, the base 11 is placed at the bottom of the main trunk so that the main trunk and the base 11 are in contact. Then the measuring personnel step on and press the base 11 to insert the fixing nail 13 into the ground soil, so that the bottom surface of the base 11 is in close contact with the ground, thereby achieving the purpose of fixing and limiting the base 11.

[0050] Second Embodiment

[0051] Please refer to the following: Figure 6 , Figure 7 and Figure 8 The evaluation device for seedling measurement also includes a limiting structure 6 and a resetting structure 7. A limiting groove 111 is also provided on the base 11. The resetting structure 7 is fixedly installed in the limiting groove 111, and the limiting structure 6 is slidably installed on the resetting structure 7.

[0052] When measuring the diameter at breast height (DBH) of seedlings, it is often encountered that the main trunk of the seedling is bent. At this time, after the base 11 is attached to the main trunk, the first clamping plate 45 and the second clamping plate 52 are far away from the main trunk and cannot be clamped for measurement.

[0053] In this embodiment, the load-bearing rod 12 is rotatably connected to the base 11. The output end of the limiting structure 6 is inserted into the load-bearing rod 12 to limit its movement. After the base 11 is fixed by the fixing nail 13, the measuring personnel step on the limiting structure 6 with their feet. The limiting structure 6 slides downward on the reset structure 7 into the limiting groove 111, releasing the limitation on the load-bearing rod 12. The measuring personnel can then adjust the angle of the load-bearing rod 12 to facilitate clamping and measuring the diameter at breast height of the seedling trunk. After the measurement is completed, the load-bearing rod 12 is adjusted to the initial position, and the stepping on the limiting structure 6 is stopped. The reset structure 7 pushes the limiting structure 6 upward, and the output end of the limiting structure 6 is inserted into the load-bearing rod 12 to limit its movement again. This achieves the effect of adjusting the angle of the load-bearing rod 12, thereby facilitating the measurement of the bent trunk.

[0054] Please refer to the following: Figure 7 and Figure 8 The evaluation device for seedling measurement also includes a limiting structure 6, which includes a pedal 61 and a fixing rod 62. The pedal 61 is slidably mounted on the reset structure 7, and the fixing rod 62 is fixedly mounted on the pedal 61.

[0055] When adjusting the angle of the load-bearing rod 12, the measuring personnel step on the pedal 61 with their foot, sliding the pedal 61 downward along the reset structure 7 into the limiting groove 111. The pedal 61 drives the fixed rod 62 to move downward, releasing the limitation on the load-bearing rod 12. After the measurement is completed, the foot is released from the pedal 61, and the reset structure 7 pushes the pedal 61 and the fixed rod 62 upward, re-inserting the fixed rod 62 into the load-bearing rod 12, thus limiting the load-bearing rod 12 again.

[0056] Please refer to the reference again. Figure 7 and Figure 8 The evaluation device for seedling measurement also includes a reset structure 7, which includes a second limiting rod 71 and a second elastic element 72. The second limiting rod 71 is fixedly installed in the limiting groove 111, and the second elastic element 72 is fixedly installed between the base 11 and the pedal 61 and is sleeved on the second limiting rod 71.

[0057] When the measuring personnel step down on the pedal 61, the pedal 61 drives the fixed rod 62 to slide on the second limiting rod 71, and at the same time compresses the second elastic element 72. The second elastic element 72 stores elastic potential energy. When the measurement is completed, the pedal 61 is released, the second elastic element 72 releases elastic potential energy, and pushes the pedal 61 and the fixed rod 62 upward, so that the fixed rod 62 is inserted into the load-bearing rod 12 again, thereby achieving the purpose of limiting the load-bearing rod 12.

[0058] The working principle of the seedling measurement and evaluation device provided by this utility model is as follows:

[0059] During measurement, the surveyor places the base 11 on the ground at the base of the seedling, presses the main trunk of the seedling against the surface of the second clamping plate 52, and simultaneously steps on and presses the base 11 to insert the fixing nail 13 into the ground soil. Then, the surveyor holds the protective shell 21 and presses down on the sliding sleeve 22. The sliding sleeve 22 slides on the first limiting rod 23 and simultaneously compresses the first elastic element 24. The sliding sleeve 22 drives the toothed plate 25 to move into the protective shell 21. The toothed plate 25 drives the transmission gear 32 and the rotating shaft 31 to rotate. The rotating shaft 31 drives the first transmission wheel 33 to rotate. The first transmission wheel 33 drives the second transmission wheel 42 and the threaded rod 41 to rotate through the transmission belt 34, driving the slider. 43 drives the pointer 44 and the first clamping plate 45 to slide. When the first clamping plate 45 contacts the tree, the second clamping plate 52 and the first clamping plate 45 clamp and fix the main trunk of the seedling. Then the measuring personnel record the scale indicated by the pointer 44 on the scale plate 51. After the measurement is completed, the sliding sleeve 22 is released, and the first elastic element 24 pushes the sliding sleeve 22 to move to the initial position. At the same time, the toothed plate 25 drives the transmission gear 32 to move in the opposite direction, releasing the clamping of the main trunk of the seedling by the first clamping plate 45 and resetting the pointer 44. This achieves the purpose of measuring the diameter at breast height, avoiding the need for the measuring personnel to squat and stand up to perform the measurement operation, improving work efficiency and reducing the workload of the measuring personnel. A pedal 61 and a second elastic element 72 are provided. When adjusting the angle of the load-bearing rod 12, the measuring personnel step on the pedal 61 with their foot. The pedal 61 drives the fixed rod 62 to slide on the second limiting rod 71, releasing the limitation on the load-bearing rod 12. At the same time, the second elastic element 72 is squeezed. After the measurement is completed, the pedal 61 is released, and the second elastic element 72 pushes the pedal 61 and the fixed rod 62 upward, inserting the fixed rod 62 back into the load-bearing rod 12, thus achieving the purpose of limiting the load-bearing rod 12.
