Description
Technical Field

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Reference Figures 1 to 8 This utility model discloses a tree ring sample positioning and cutting device, including: a first body 1 and a second body 2, the first body 1 and the second body 2 are connected by a first connecting part and a second connecting part, the first body 1 and the second body 2 form a clamping cavity, the first body 1 and / or the second body 2 are provided with an operation window 3, the operation window 3 is provided with a collection part, and the first body 1 and the second body 2 are both provided with clamping parts;
[0033] The clamping part includes a plurality of screws 16, which are threadedly connected to the first body 1 and the second body 2 respectively. The screws 16 pass through the first body 1 and the second body 2 and are fixed to the top plate 17. The plurality of screws 16 located on the first body 1 and the second body 2 are arranged at equal intervals in the circumference.
[0034] A clamping cavity is formed between the first main body 1 and the second main body 2. The tree to be sampled is located in the clamping cavity. Then, by adjusting multiple screws, the top plate 17 abuts against the outer wall of the tree, thereby completing the fixation of the first main body 1, the second main body 2 and the tree. Then, the collection unit is installed in the operation window, and the collection unit passes through the operation window to collect samples from the tree.
[0035] This invention incorporates a clamping part, which, by adjusting the clamping part, allows the device to fix and sample trees of different diameters, thus enhancing its applicability.
[0036] In a further optimized design, the first connecting part includes two first hinge seats 4, which are fixed to one side of the first main body 1. The two first hinge seats 4 are respectively close to both ends of the first main body 1. The first hinge seats 4 are hinged to a second hinge seat 5 through a first hinge shaft 6. The second hinge seat 5 is fixed to one side of the second main body 2.
[0037] The two first hinge seats 4 on one side of the first main body 1 are hinged to the second hinge seat 5 on one side of the second main body 2.
[0038] Further optimization of the scheme: the second connecting part includes a fixing plate 7, which is fixedly installed on the outer wall of the first main body 1. The fixing plate 7 is away from the first hinge seat 4. A through hole is opened in the middle of the fixing plate 7. An optical shaft 8 is rotatably connected in the through hole. The optical shaft 8 is arranged along the axial direction of the first main body 1. The top end of the optical shaft 8 extends out of the fixing plate 7 and is coaxially fixed with a screw head 10. The bottom end of the optical shaft 8 extends into the ratchet box 11 and is connected to the ratchet mechanism.
[0039] A through groove 9 is provided in the middle of the optical axis 8. A strip 12 is inserted through the through groove 9. Both ends of the strip 12 extend out of the through groove 9. A stop block 13 is fixed to one end of the strip 12. The cross-sectional area of the stop block 13 is larger than the cross-sectional area of the through groove 9. A hook 14 is fixed to the other end of the strip 12. The hook 14 is detachably connected to the hanging ear 15. The hanging ear 15 is fixed to the outer wall of the second body 2. The hanging ear 15 is away from the second hinge seat 5.
[0040] One end of the strip 12 is connected to the lug 15 on the outer wall of the second body 2 via a hook 14. In this way, the first body 1 and the second body 2 are initially connected together, preparing for the subsequent clamping operation. Then, the optical axis 8 is rotated by rotating the screw head 10. Since the optical axis 8 is connected to the ratchet mechanism, its rotation is restricted by the ratchet mechanism and can only rotate in one direction, thereby locking the relative position of the first body 1 and the second body 2. During the rotation of the optical axis 8, the strip 12 slides in the through groove 9, and the stop block 13 acts as a limit to prevent the strip 12 from coming out of the through groove 9. In this way, the second connecting part realizes the connection and locking of the first body 1 and the second body 2, ensuring the stability and reliability of the device when clamping trees.
[0041] In a further optimized design, multiple third hinge seats 22 are fixedly connected to the outer side walls of both the first main body 1 and the second main body 2. The third hinge seats 22 are located at the lower part of the first main body 1 and the second main body 2. The multiple third hinge seats 22 are arranged at equal intervals around the periphery. The fixed end of the first telescopic rod 21 is hinged to the third hinge seat 22 through the second hinge shaft 23.
[0042] The top end of the first telescopic rod 21 is connected to the third hinge seat 22 via the second hinge shaft 23. The length of the telescopic rod can be adjusted by its telescopic function to facilitate sampling of trees at different heights. When the tree is placed into the clamping cavity and fixed by the clamping part, the first telescopic rod 21 provides stable support for the device through the third hinge seat 22.
[0043] The scheme is further optimized. The acquisition unit includes a motor 24. Two supports 25 are fixedly connected to one end of the motor 24. The two supports 25 are centrally symmetrically arranged. A lead screw 26 is rotatably connected inside the support 25. The lead screw 26 extends out of the support 25 away from the motor 24 and is fixedly connected to a lever 27. One end of a second telescopic rod 28 is threadedly connected to the lead screw 26. The other end of the second telescopic rod 28 passes through the support 25 and is fixedly connected to a slot 29. The two second telescopic rods 28 are horizontal and parallel. The slot 29 is inserted into the operation window 3 and is adapted to the inner edge of the operation window 3.
[0044] Two cutting blades 31 are detachably connected to the output shaft of motor 24 via bolt 32.
[0045] First, the motor 24 is started. The output shaft of the motor drives the lead screw 26 to rotate. Since the lead screw 26 is threadedly connected to the second telescopic rod 28, the rotation of the lead screw will cause the second telescopic rod 28 to move along the lead screw axis, thereby driving the slot 29 to assemble with the operating window 3, realizing the positioning and adjustment of the tree. At the same time, the two cutting blades 31 connected by bolts 32 on the output shaft of the motor 24 rotate at high speed under the drive of the motor. When the slot 29 moves to the appropriate position, the cutting blades 31 are aligned with the sample to perform the cutting operation, completing the collection of tree ring samples.
[0046] The two cutting blades 31 are detachably connected to the output shaft of the motor 24 by bolts 32. After sampling is completed, one of the cutting blades 31 can be removed to facilitate the extraction of the sample.
[0047] The scheme is further optimized so that both the first main body 1 and the second main body 2 are arc-shaped, and the concave surfaces of the first main body 1 and the second main body 2 are arranged opposite each other, forming a clamping cavity.
[0048] The concave surfaces of the arc-shaped structures of the first body 1 and the second body 2 are placed opposite each other to form a complete clamping cavity for accommodating the tree to be cut.
[0049] In a further optimized design, a roller 30 is rotatably connected to the inner wall of slot 29, and the roller 30 slides in contact with the operation window 3.
[0050] When the slot 29 moves within the operating window 3, the roller 30 on its inner wall will slide into contact with the inner edge of the operating window 3. The rolling of the roller 30 reduces the friction between the slot 29 and the operating window 3, thereby allowing the slot 29 to move more smoothly within the operating window 3, ensuring that the positioning and cutting operations of the acquisition unit are more stable and accurate.
[0051] In a further optimized design, a square shaft 18 is fixedly connected to one end of the screw 16 that extends out of the first main body 1 / second main body 2, and a handwheel 19 is fixedly connected to the square shaft 18.
[0052] The rotation of the handwheel 19 drives the square shaft 18, which in turn drives the screw 16 to rotate. The rotation of the screw 16 causes it to move along the thread direction within the first body 1 or the second body 2, thereby achieving the clamping or loosening operation of the tree.
[0053] Further optimization of the scheme: The ratchet mechanism includes a mounting box 1101 fixedly installed on one side of the ratchet box 11. A pull rod 1102 is slidably connected inside the mounting box 1101. One end of the pull rod 1102 extends out of the mounting box 1101, and a pawl 1104 is fixedly connected to the other end of the pull rod 1102. A spring 1103 is sleeved on the outside of the pull rod 1102. The two ends of the spring 1103 abut against the pawl 1104 and the inner wall of the mounting box 1101, respectively.
[0054] A ratchet 1105 is rotatably connected inside the ratchet box 11. The ratchet 1105 is coaxially fixed to the optical axis 8 and engages with the pawl 1104.
[0055] When the optical axis 8 rotates, the ratchet 1105 rotates coaxially. Since the pawl 1104 is always engaged with the ratchet 1105 under the action of the spring 1103, the ratchet 1105 can only rotate in one direction. When the optical axis 8 needs to rotate in the opposite direction, the pull rod 1102 is pulled to overcome the elastic force of the spring 1103 and make the pawl 1104 disengage from the ratchet 1105. At this time, the optical axis 8 can rotate freely in the opposite direction. After the pull rod 1102 is released, the pawl 1104 re-engages with the ratchet 1105 under the action of the spring 1103, and the one-way locking state is restored.
[0056] During use, the first body 1 and the second body 2 are first connected by the first connecting part and the second connecting part. The two first hinge seats 4 of the first connecting part are close to the two ends of the first body 1 respectively, and are hinged to the second hinge seat 5 through the first hinge shaft 6 to realize the opening and closing operation of the first body 1 and the second body 2. The fixing plate 7 of the second connecting part is installed on the outer wall of the first body 1. The optical axis 8 is rotatably connected to the fixing plate 7 through the through hole. The screw head 10 at the top is used to manually rotate the optical axis 8, and the bottom end is connected to the ratchet mechanism. The pawl 1104 of the ratchet mechanism is engaged with the ratchet 1105 under the action of the spring to realize the one-way locking of the optical axis 8. The strip 12 passes through the through groove 9 of the optical axis 8. The stop block 13 at one end prevents the strip 12 from falling out, and the hook 14 at the other end is connected to the hook ear 15 on the outer wall of the second body 2, thereby further fixing the first body 1 and the second body 2. Next, the tree is placed into the clamping cavity formed by the first main body 1 and the second main body 2. By turning the handwheel 19, the square shaft 18 and the screw 16 are rotated, causing the top plate 17 on the screw 16 to move inward, thereby clamping the tree. Then, the motor 24 of the collection unit is started. The motor 24 drives the lead screw 26 to rotate, and the second telescopic rod 28 on the lead screw 26 moves along the lead screw axis, thereby driving the slot 29 to move within the operating window 3. The roller 30 on the inner wall of the slot 29 slides in contact with the operating window 3 to reduce friction and ensure smooth movement. At the same time, the cutting blade 31 on the output shaft of the motor 24 rotates under the drive of the motor, aiming at the tree to perform the cutting operation.
