Description

[0002] Tree growth cones are a common sampling tool used in forestry research for sampling and measuring trees.
[0003] Since tree growth cones are operated manually, sampling is difficult and inefficient for hard and thick trees. A common solution is to use an external drive source to reduce manual operation. However, at the end of the sampling process, the growth cone needs to be reversed by 90°. The reversal angle controlled by the drive source is not easy to control. If the reversal angle is too large, it may affect the integrity of the sample. To address this problem, an electric growth cone for core extraction from trees is proposed. Summary of the Invention

[0028] A propulsion ring 21 is connected to the second rotating shaft 19. A telescopic shaft 18 is fixedly connected to the rear end of the propulsion cylinder 3. The telescopic shaft 18 and the first rotating shaft 17 are both connected to the output shaft 2. The propulsion cylinder 3 has multiple fixing ports 15. Multiple fixing rods 13 are connected to the inner wall of the propulsion cylinder 3. A clamping mechanism is provided on the outer side of the fixing port 15. The clamping mechanism includes a first fixing ring 6 and a second fixing ring 7 rotatably connected to the outer side of the fixing port 15. A rotating disk 11 is rotatably connected inside the propulsion cylinder 3. Multiple arc-shaped clamping grooves 14 are provided on the rotating disk 11. The inner wall of the clamping groove 14 is slidably connected to the fixing rod 13. A telescopic rod is provided between the fixing rod 13 and the inner wall of the propulsion cylinder 3. Multiple fixing grooves corresponding to the fixing rod 13 are provided on the growth cone body 5.
[0029] Reference Figures 4-7 The clamping mechanism is connected to multiple fixed rods 13. A fixed gear 9 is rotatably connected to the side wall of the first fixed ring 6 corresponding to the position of the fixed opening 15. A clamping rack 10 is slidably connected to the first fixed ring 6. The fixed gear 9 and the clamping rack 10 are meshed. A clamping block is fixedly connected to the bottom end of the clamping rack 10. Multiple connecting grooves 12 corresponding to the clamping blocks are opened on the rotating disk 11. An annular rack 8 is provided on the second fixed ring 7. The annular rack 8 is meshed with the fixed gear 9. A translation groove 27 is opened on the first fixed ring 6. A sliding frame 16 is slidably connected to the inner side wall of the translation groove 27. The sliding frame 16 is fixedly connected to the second fixed ring 7. An installation rod 26 is slidably connected inside the sliding frame 16. A fixed cavity corresponding to the installation rod 26 is provided inside the translation groove 27. A fixing pin for fixing is provided between the first fixed ring 6 and the push cylinder 3.
[0030] Reference Figure 8A rotary mechanism is provided between the rear end of the propulsion cylinder 3 and the inner wall of the mounting frame 1. The rotary mechanism includes a fixed plate slidably connected to the inner wall of the mounting frame 1. The fixed plate is connected to the sliding ring 4. A rotary shaft 25 is rotatably connected to the fixed plate. A toothed gear 23 is fixedly connected to the outer wall of the rotary shaft 25. A rotary gear ring 28 is fixedly connected to the propulsion cylinder 3. The toothed gear 23 and the rotary gear ring 28 are adapted to each other. A rotary torsion spring 24 is provided between the toothed gear 23 and the fixed plate.
[0031] Operating Procedure: When drilling wood cores, the growth cone body 5 is placed between multiple fixed rods 13. The operator then manually pulls the sliding frame 16. When pulled to the fixed cavity, the mounting rod 26 enters the mounting cavity. Simultaneously, the sliding frame 16 rotates, causing the second fixed ring 7 to rotate. When the ring rack 8 rotates, the fixed gear 9 causes the clamping rack 10 to move towards the center of the rotating disk 11, thereby causing the clamping block to enter the connecting groove 12. The mounting cavity is used to limit the position of the sliding frame 16. After that, the sliding frame 16 is pulled again. When the sliding frame 16 is pulled, the first fixed ring 6 rotates, causing the rotating disk 11 to rotate. Under the action of the clamping groove 14 and the telescopic rod, multiple fixed rods 13 move towards the growth cone body 5. The multiple fixed rods 13 can clamp the growth cone body 5. The fixed rods 13 and the fixed groove can prevent the growth cone body 5 from detaching.
[0032] Then, by controlling the external electric drill bit, the output shaft 2 is rotated. When the output shaft 2 rotates, the first rotating shaft 17 and the telescopic shaft 18 are rotated under the action of the first bevel gear and the second bevel gear. The telescopic shaft 18 is used to drive the propulsion cylinder 3 to rotate. When the first rotating shaft 17 rotates, the second rotating shaft 19 can be rotated by setting a rotating gear. When the second rotating shaft 19 rotates, the moving rod 20 can move forward under the action of the thread. Through the set propulsion ring 21, the propulsion cylinder 3 can move forward, thereby pushing the growth cone body 5 into the tree. This method can keep the device stationary. The existing method requires the operator to move the device synchronously, which consumes the operator's physical strength and reduces the efficiency of drilling wood cores. This method can greatly save the operator's physical strength and improve the efficiency of drilling wood cores.
[0033] Furthermore, when the push cylinder 3 rotates, the rotary gear ring 28 is always meshed with the toothed gear 23. As the rotary gear ring 28 rotates with the push cylinder 3, it stores a portion of the elastic potential energy in the rotary torsion spring 24. When the toothed gear 23 rotates to the notch, it remains in this position, ensuring that the stored elastic potential energy remains consistent. When the output shaft 2 stops rotating, the elastic potential energy on the rotary torsion spring 24 is released, allowing the push cylinder 3 to reverse 90 degrees, thus controlling the integrity of the wood core sampling.
[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
