Description

Technical Field

[0001] This utility model relates to the field of forest tree growth technology. More specifically, this utility model relates to an auxiliary tool for measuring forest tree growth. Background Technology

[0002] In forestry seedling cultivation and research projects, it is frequently necessary to investigate the growth of seedlings. The subjects of these investigations are seedlings in nursery beds, characterized by their large numbers and high density between rows. Measurements must be taken for each row of target trees in the nursery bed. This is typically done by manually separating the seedlings, using wooden boards, or binding the seedlings on both sides of the target tree with rope. Investigating each target tree requires repeatedly separating each seedling on both sides, and measurements are often interfered with by the seedlings on either side, wasting time and easily causing data errors. Currently, the use of ropes or wooden boards to separate seedlings during investigations easily damages them, affecting later growth and ultimately impacting the overall production quality or experimental results. This makes it difficult to guarantee the authenticity, completeness, and consistency of the results of forestry field surveys. Utility Model Content

[0031] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0033] like Figures 1-4 As shown, an embodiment of this utility model provides an auxiliary tool for measuring tree growth, comprising:

[0034] Two bases 1, positioned opposite each other;

[0035] Two connecting segments 2, the lower ends of which are rotatably connected to the upper ends of the two bases 1 respectively;

[0036] Connecting strut 3, the two connecting segments 2 are connected by the connecting strut 3, and the distance between the upper ends of the two connecting segments 2 is greater than the distance between their lower ends;

[0037] Tree-blocking strip 4, two of the tree-blocking strips 4 are detachably installed on the connecting section 2 to form a tree-blocking strip.

[0038] In this embodiment, when measuring the target tree, two connecting segments 2 are rotatably mounted on two bases 1, and tree-blocking strips 4 are installed on both sides of the connecting segments 2. The two bases 1 are then placed opposite each other on the ground on both sides of the target tree. The two tree-blocking strips 4 on the two bases 1 form a long strip of tree-blocking strip. A connecting support rod 3 is placed between the two connecting segments 2. One end of the connecting support rod 3 is connected to one of the connecting segments 2, and the other end of the connecting support rod 3 is connected to the other connecting segment 2. The distance between the upper ends of the two connecting segments 2 is greater than the distance between their lower ends. During this process, the connecting segments 2 will rotate relative to the base 1. The two tree-blocking strips can push the 2-3 seedlings on both sides of the target tree outward, separating the target tree from the seedlings on both sides. In this way, the measurement of the target tree will not be interfered with by the seedlings on both sides.

[0039] The target of the forest growth measurement auxiliary tool in this embodiment is seedlings. During the survey, it is pushed to both sides and the seedlings are pushed in the opposite direction. The device will not be suspended by the seedlings, and the wooden boards and ropes will not break or injure the seedlings.

[0040] Preferably, as another embodiment of this utility model, such as Figure 5 As shown, a plurality of positioning grooves 21 are vertically spaced on one side of the connecting section 2, and the two ends of the connecting support rod 3 extend into the two positioning grooves 21 at the same height of the two connecting sections 2 respectively.

[0041] In this embodiment, when both connecting segments 2 are vertical, the distance between the two positioning slots 21 at the same height of the two connecting segments 2 is less than the length of the connecting strut 3. At this time, both ends of the connecting strut 3 extend into the two positioning slots 21 respectively, which will push the two connecting segments 2 apart, causing the connecting segments 2 to rotate relative to the base 1 and push the seedlings on both sides of the target tree outward. At the same time, since the target tree also has a reaction force on the connecting segments 2, the two connecting segments 2 move closer to each other, thereby fixing the connecting strut 3 to the two connecting segments 2. Since the connecting strut 3 is always horizontal while the connecting segments 2 rotate, the end of the connecting strut 3 needs to be able to slide in the positioning slot 21, and the end of the strut only needs to abut against the inner wall of the positioning slot 21.

[0042] Furthermore, in this embodiment, multiple positioning slots 21 are vertically spaced along one side of the connecting segment 2. Since the lower end of the connecting segment 2 remains unchanged despite rotating around it, the included angle between the two connecting segments 2 will be different when the connecting support rod 3 is inserted into the positioning slots 21 at different heights. When the depth of the positioning slots 21 is the same, the included angle between the two connecting segments 2 will increase as the connecting support rod 3 is inserted from top to bottom into different positioning slots 21, which can push the seedlings on both sides of the target tree further outward. In actual use of the measuring auxiliary tool, the two ends of the connecting support rod 3 can be inserted into the positioning slots 21 at appropriate heights according to actual needs.

[0043] Preferably, as another embodiment of the present invention, a plurality of positioning grooves 21 are also provided vertically at intervals on the other side of the connecting segment 2.

[0044] In this embodiment, since the actual measurement of tree growth requires measuring each seedling in sequence, multiple positioning slots 21 are also vertically spaced on the other side of the connecting section 2. After measuring a target tree, when measuring the next target tree next to it, only one side of the base 1 needs to be moved. The base 1 close to the next target tree is not moved. The base 1 far from the next target tree is moved to the other side. Then the connecting support rod 3 is connected to the two connecting sections 2, which can separate the next target tree from the seedlings around it, reducing the movement time of the measurement auxiliary tool.

[0045] Preferably, as another embodiment of this utility model, such as Figure 6 As shown, the depth of the plurality of positioning grooves 21 gradually decreases from top to bottom.

[0046] In this embodiment, the depth of the multiple positioning slots 21 is set to gradually decrease from top to bottom. In this way, when the depth of the multiple positioning slots 21 is the same, the included angle between the two connecting segments 2 will be larger when the connecting support rod 3 is inserted into different positioning slots 21 from top to bottom, and the measuring auxiliary tool can separate the seedlings from a larger range.

[0047] Preferably, as another embodiment of this utility model, such as Figure 4 As shown, the two ends of the connecting strut 3 are respectively rotatably connected to positioning blocks 31 corresponding to the positioning groove 21.

[0048] In this embodiment, since the two connecting segments 2 will rotate, in order to ensure the stability of the connection between the connecting strut 3 and the connecting segment 2, positioning blocks 31 are rotatably set at both ends of the connecting strut 3. The positioning blocks 31 are T-shaped, and the positioning groove 21 is also set to be T-shaped to match the positioning blocks 31. The positioning blocks 31 can be tightly embedded in the positioning groove 21 and rotate relative to the connecting strut 3 as the connecting segment 2 rotates.

[0049] Preferably, in another embodiment of the present invention, the connecting strut 3 is a telescopic strut.

[0050] In this embodiment, the connecting strut 3 can be an existing manual telescopic strut, so the length of the connecting strut 3 can be adjusted as needed to further increase the included angle between the two connecting segments 2 and expand the range that the measuring auxiliary tool can separate the seedlings.

[0051] Preferably, as another embodiment of this utility model, such as Figure 3 As shown, the lower end of the connecting section 2 is connected to the round rod 23 through the connecting part 22. The upper end of the base 1 is provided with a first groove 11 corresponding to the round rod 23. The two side walls of the first groove 11 are provided with a second groove 12 corresponding to the connecting part 22.

[0052] In this embodiment, the first groove 11 and the second groove 12 form a cross-shaped groove. The round rod 23 can rotate in the first groove 11, thereby ensuring the rotation between the connecting section 2 and the base 1. At the same time, in order to prevent the connecting part 22 from causing resistance to the rotation of the connecting section 2, the second groove 12 is provided on the two side walls of the first groove 11. When the connecting section 2 rotates, the connecting part 22 rotates in the second groove 12.

[0053] Preferably, in another embodiment of the present invention, the connecting section 2 is provided with a plurality of connecting grooves 24 vertically spaced on both sides, and the tree-blocking strip 4 is provided with a connector 41 corresponding to the connecting groove 24 at one end, and the connector 41 can be embedded in any of the connecting grooves 24.

[0054] In this embodiment, the tree-blocking strip 4 can be an arc-shaped plate, ensuring uniform force distribution and preventing skewing. Two tree-blocking strips 4 on the same side form an inwardly convex arc-shaped tree-blocking band, expanding the tree-blocking range of the tree-blocking strip 4. The connecting groove 24 can be T-shaped, and the connector 41 uses a matching T-shaped block, allowing the connector 41 to be embedded in either connecting groove 24, thereby fixing the tree-blocking strip 4 to the connecting section 2.

[0055] Preferably, as another embodiment of the present invention, it further includes:

[0056] Two connecting strips 5 are spaced apart between the two bases 1 and are detachably connected to the two bases 1 respectively.

[0057] In this embodiment, the bases 1 are connected by two connecting strips 5, which can improve the stability of the measuring auxiliary tool. Specifically, the connecting strips 5 are evenly distributed with multiple positioning holes 51, and the upper ends of the bases 1 are provided with elastic clips 13 on both sides. The elastic clips 13 can be embedded in any positioning hole 51. As needed, two opposite elastic clips 13 can be respectively embedded in the two positioning holes 51 of the connecting strips 5 on the same side. In this way, the two bases 1 can be connected and fixed at different distances by the two connecting strips 5, thereby adjusting the distance between the two bases 1 according to the different row spacing of the survey object.

[0058] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
