DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1, as Figure 2 , 3 As shown in Figure 9, an adjustable tree sample sampling device includes an adjustable tree sample sampling device, including a fixed rod 8, on the side walls at both ends of the fixed rod 8, a driven roller 3 and a driving roller 9 are rotatably connected respectively through a rotating shaft, and a roller driving mechanism 4 for driving the driving roller 9 to rotate is installed on the fixed rod 8, and the roller driving mechanism 4 includes a second motor 401 fixed on the side wall of the fixed rod 8, the second motor 401 is located at one end of the fixed rod 8 close to the counterweight box 1, and the output shaft of the second motor 401 and one end of the rotating shaft of the driving roller 9 are both installed with a transmission roller 403, and a transmission belt 402 is connected between the two transmission rollers 403. The second motor 401 is arranged on one side of the driven roller 3, which can lower the center of gravity of the device and improve the stability of the device during the upward climbing process. The roller driving mechanism 4 can also adopt a mode in which the motor directly drives the driving roller 9; Both sides of the rotating shaft on which the driven roller 3 is installed are rotatably sleeved with lifting rings 101, and the bottom ends of the lifting rings 101 are commonly connected to a counterweight box 1, and components such as batteries are installed in the counterweight box 1, so that the center of gravity of the entire device is always maintained at one end of the driven roller 3. When the device is installed on a tree trunk, the device and the tree trunk are quickly clamped and fixed by the gravity effect of the tilt of one end of the device; A sampling mechanism 7 for sampling tree samples is installed on one side of the top of the fixed rod 8. The sampling mechanism 7 includes a mounting box 701 mounted on the top surface of the fixed rod 8. A sliding frame 703 is slidably connected inside the mounting box 701. The sliding frame 703 is rotatably connected to a sampling drill pipe 705 on one side of the opening of the mounting box 701. A motor 3 707 is installed inside the sliding frame 703. The output shaft of the motor 3 707 is connected to a gear 706. The gear 706 is meshed with a transmission gear ring 704 at one end of the sampling drill pipe 705, and a telescopic rod 3 702 is installed between the other side of the sliding frame 703 and the inner wall of the mounting box 701.

[0021] When in use: the opening of the device is hung on the trunk of the tree, the device is tilted, the active roller 9 is located at the top, and the driven roller 3 is located at the bottom. The center of gravity of the device is on one side, so the device and the trunk can be quickly clamped and fixed. It can be suitable for trees with trunks of various thicknesses. The motor 2 401 on the roller drive mechanism 4 is started, and the active roller 9 is driven to rotate through the transmission belt 402 and the transmission roller 403, thereby driving the device to climb upward. During the climbing process, when the diameter of the trunk changes, due to the effect of gravity, the inclination angle of the device gradually increases, but it can still be stably clamped and fixed on the trunk. After climbing to a suitable height, the sampling mechanism 7 is started, and the motor 3 707 in the sampling mechanism 7 drives the sampling drill pipe 705 to rotate. At the same time, the output shaft of the telescopic rod 3 702 drives the sampling drill pipe 705 to move to one side, so that the trunk can be drilled and sampled. After completion, the motor 2 401 on the roller drive mechanism 4 rotates in the opposite direction to drive the device to move downward to the bottom.

[0022] Embodiment 2, as Figure 1 , 2 , 5, 6, and 8, which are different from the embodiment 1, an auxiliary clamping mechanism 5 is also installed on the fixed rod 8; the auxiliary clamping mechanism 5 includes a swing rod 506 hinged at the middle position of the bottom end of the fixed rod 8, and a clamping rod 508 is installed on one side of the bottom end of the swing rod 506; the clamping rod 508 and the driven roller 3 are located on the same horizontal plane; The auxiliary clamping mechanism 5 also includes a vertically arranged sliding rod 501, on which a counterweight block 502 is slidably sleeved, and one side of the top end of the sliding rod 501 is rotatably connected to the side wall of the fixed rod 8 through a rotating pin 503. A rope threading ring 504 is installed at the top end of the sliding rod 501, and a connecting rope 505 is passed through the rope threading ring 504, the two ends of which are respectively connected to the counterweight block 502 and the swing rod 506.

[0023] The clamping rod 508 is slidably sleeved with a sliding tube 509 along its length direction, the outside of the sliding tube 509 is rotatably sleeved with a clamping roller 507, and locking screws 510 are installed at both ends of the sliding tube 509.

[0024] In order to further improve the stability of the device during sampling, a clamping and locking mechanism 6 is also installed on the auxiliary clamping mechanism 5. The clamping and locking mechanism 6 includes a telescopic rod 602. The output shaft of the telescopic rod 602 is connected to a U-shaped sliding rod 603 that passes through the fixed rod 8. An arc-shaped toothed ring 601 is fixed to the opening of the U-shaped sliding rod 603. The arc-shaped toothed ring 601 passes through and is slidably connected to the sliding hole 5061 on the swing rod 506, and the side wall of the sliding hole 5061 is provided with a locking tooth that is movably engaged with the arc-shaped toothed ring 601.

[0025] In order to further improve the stability of the device when it moves up and down, a limiting arc surface 5071 that fits the outer surface of the tree is provided on the outer wall of the clamping roller 507. The setting of the limiting arc surface 5071 can make the outer surface of the tree fit better on the clamping roller 507, thereby preventing the device from deviating when the device moves up and down.

[0026] When the device is in use, when it is hung on the trunk of a tree, the counterweight 502 drives the swing rod 506 to move to one side through the connecting rope 505, and the clamping rod 508 and the clamping roller 507 on the swing rod 506 cooperate with the driven roller 3 to further improve the clamping stability between the device and the tree trunk. When the diameter of the tree trunk changes, the counterweight 502 moves up and down on the sliding rod 501 under the action of gravity, thereby driving the swing rod 506 to move through the connecting rope 505, and the swing rod 506 drives the clamping rod 508 and the clamping roller 507 to always be in close contact with the tree trunk. After moving to a suitable sampling height, the telescopic rod 602 on the clamping and locking mechanism 6 drives the U-shaped sliding rod 603 and the arc-shaped toothed ring 601 to move to one side, and the caliper in the sliding hole 5061 is clamped and fixed to the arc-shaped toothed ring 601. At this time, the clamping stability between the device and the tree trunk is further enhanced, which facilitates subsequent sampling operations and provides higher stability for subsequent sampling operations.

[0027] Embodiment 3, as Figure 1 , 2As shown in , 4, and 9, unlike Examples 1 and 2, it also includes a rotating drive mechanism 2 installed at the bottom end of the counterweight box 1, and the rotating drive mechanism 2 includes a fixed frame 202 fixed at the bottom end of the counterweight box 1, and the external sliding sleeve of the fixed frame 202 is connected with a moving frame 203, and a telescopic rod 201 is connected between the moving frame 203 and the fixed frame 202, and a motor 204 is installed on one side of the top end of the moving frame 203, and the output shaft of the motor 204 is connected to a rotating roller 205.

[0028] During use: When encountering lateral branches of trees that block the upward movement, start the telescopic rod 201, and the output shaft of the telescopic rod 201 drives the moving frame 203 to move to one side on the fixed frame 202, thereby driving the rotating roller 205 to approach the surface of the trunk and contact the trunk, and then the output shaft of the motor 204 drives the rotating roller 205 to rotate, and the entire device can be driven to rotate on the trunk through the rotating drive mechanism 2, so that the opening of the device moves to the branch, and then the roller drive mechanism 4 is started to drive the device to move up and down to avoid the obstruction of the tree branches.

[0029] like Figure 1 , 2 As shown in Figure 6, in order to further improve the stability of the movement of the rotating drive mechanism 2, a locking card 103 is fixedly connected to the top of the U-shaped sliding rod 603 on the clamping and locking mechanism 6 through a locking rod 104, and a locking toothed ring 102 is installed on the side wall of the lifting ring 101 close to the fixed rod 8. When the clamping and locking mechanism 6 moves downward through the locking rod 104, the locking card 103 and the locking toothed ring 102 are locked and fixed. When the clamping and locking mechanism 6 is actuated, the U-shaped sliding rod 603 drives the locking card 103 to be clamped on the locking toothed ring 102 through the locking rod 104, thereby realizing the locking and fixation of the lifting ring 101. The stability of the counterweight box 1 connected to its bottom end and the rotating drive mechanism 2 at its bottom end can be achieved through the lifting ring 101, thereby preventing the rotating drive mechanism 2 from shaking during operation.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
