Description

Technical Field

[0001] This utility model relates to the field of forestry seedling correction technology, specifically a forestry slanted tree correction device. Background Technology

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of trees to play a protective role. It is an important component of the national economy. When planting forestry seedlings, if seedlings tilt due to strong winds or loose soil, corrective measures are necessary.

[0003] According to Chinese Patent Publication No. CN216438048U, entitled "A Tree Corrector for Forestry," the device includes a correction board. A positioning clamp is fixedly connected to the lower end of the side of the correction board via two connecting rods. A correction clamp is fitted to the upper end of the side of the correction board. A mounting frame is fixedly connected to the other side of the correction board. A guide wheel is fitted to the end of the mounting frame away from the correction board. A fixing mechanism is provided at the lower end of the correction board. A counterweight assembly is provided on the correction board. This invention replaces the traditional correction device structure, eliminating the need for workers to adjust the device during the correction process, improving the device's practicality, and preventing the correction board from tilting or tipping over during the correction process, thus ensuring the stability of the device.

[0004] The device straightens trees by pulling ropes to move the clamps; however, it cannot support the trunk during the straightening process, and the swaying that occurs in windy weather increases the risk of damage to the trees during the straightening process. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a forestry tree straightening device, which has the function of supporting the tree trunk during the straightening process, thereby resisting the swaying caused by strong winds and reducing the damage to the trees during the straightening process.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A forestry tree straightening device includes a base. A support rod extends forward from each of the two front ends of the base. A straightening rod is mounted on each of the two support rods. The lower ends of the two straightening rods are rotatably mounted on the two support rods. A bolt is threaded to the upper end of each straightening rod, and a clamp is rotatably connected to the end of each bolt. Each straightening rod is fixedly connected to one end of a pull rope. The other end of the pull rope passes through a hole in a locking block and is fixedly connected to a counterweight. The locking block is fixedly mounted on the base by a bracket. Several locking balls are spaced apart on the pull rope. A groove is provided inside the locking block perpendicular to the hole. A slider slides within the groove. A spring is provided between the upper end of the slider and the top of the groove. A locking pin extends from the lower end of the slider into the hole, with the front end of the portion of the locking pin inside the hole being inclined and the rear end being vertical.

[0008] Preferably, a pulley is provided at both the front and rear ends of the locking block.

[0009] Preferably, both ends of the through hole are provided with flared openings.

[0010] Preferably, the slider is fixedly connected to the lower end of the connecting rod, and the upper end of the connecting rod passes through the locking block and is fixedly connected to the pull ring.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] First, place the base on the side of the tree root, rotate the two straightening rods so that they are parallel to each other on both sides of the trunk, rotate the bolt, the bolt rotates and pushes the clamp set at the end of the bolt to clamp the trunk, the counterweight pulls one end of the rope, the other end of the rope passes through the hole on the locking block and pulls the straightening rod, causing the straightening rod to rotate and drive the trunk to be straightened. The rope can slowly pull the trunk to be straightened, avoiding excessive straightening and damage to the seedling. At the same time, it does not require the staff to make multiple adjustments, reducing the workload.

[0013] Secondly, when encountering strong winds that cause trees to sway, the trunk pulls the straightening rod in the direction of tilting. This causes the straightening rod to pull the rope in the direction of tilting, making the locking ball contact the rear end face of the locking pin located inside the through hole. Since this end face is vertical, the locking ball will not push the locking pin upwards, allowing the rope to hold the trunk and prevent it from tilting again. At the same time, the two straightening rods clamp the trunk from both sides, preventing it from swaying to either side in the direction of tilting. This provides support for the trunk during the straightening process, thus resisting the swaying caused by strong winds and reducing damage to the tree during the straightening process.

Detailed Implementation

[0018] 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.

[0019] This utility model provides the following technical solution:

[0020] Combination Figures 1 to 3 As shown in this embodiment, a forestry tree straightening device includes a base 1. A support rod 2 extends forward from each of the two front ends of the base 1. A straightening rod 3 is mounted on each of the two support rods 2. The lower ends of the two straightening rods 3 are rotatably mounted on the two support rods 2. A bolt 4 is threadedly connected to the upper end of each of the two straightening rods 3. A clamping plate 5 is rotatably connected to the end of each of the two bolts 4. Both straightening rods 3 are fixedly connected to one end of a pull rope 6. The other end of the pull rope 6 passes through a hole 8 on a locking block 7 and is then fixedly connected. On the counterweight 9, the locking block 7 is fixedly mounted on the base 1 by the bracket 10. Several locking balls 11 are spaced apart on the pull rope 6. The inside of the locking block 7 is provided with a groove 12 perpendicular to the through hole 8. A slider 13 is slidably mounted in the groove 12. A spring 14 is provided between the upper end of the slider 13 and the top of the groove 12. A locking pin 15 extending into the through hole 8 is provided at the lower end of the slider 13. The front end of the locking pin 15 inside the through hole 8 is inclined, and the rear end of this part is vertical.

[0021] Place base 1 on the side of the tree root, with the tree root positioned at the midpoint of the line connecting the bottoms of the two straightening rods 3. Rotate base 1 so that the two support rods 2 are aligned with the tree's tilt direction. Rotate the two straightening rods 3 so that they are parallel to each other on both sides of the tree trunk. Rotate bolt 4; the rotation of bolt 4 will push the clamp 5 at the end of bolt 4 to clamp the tree trunk. Adjust the length of the pull rope 6 so that the distance between the bottom of the counterweight 9 and base 1 is equal to the distance the tree needs to be straightened. The counterweight 9 pulls one end of the pull rope 6, and the other end of the pull rope 6 passes through the through hole 8 on the locking block 7 and pulls the straightening rod 3, causing the straightening rod 3 to rotate and straighten the tree trunk. When block 9 pulls the rope 6 through the hole 8, the locking ball 11 on the rope 6 enters the hole 8 and contacts the locking pin 15. Since the front end of the locking pin 15 is inclined, under the pressure of the locking ball 11, the locking pin 15 drives the slider 13 to slide upward in the groove 12. At the same time, the spring 14 is compressed, and the locking pin 15 moves out of the hole 8, allowing the locking ball 11 to pass through. After the locking ball 11 passes through, under the pushing force of the spring 14, the end of the locking pin 15 re-enters the hole 8, so that the rope 6 can slowly pull the tree trunk for correction, avoiding excessive correction and damage to the seedlings. At the same time, it does not require the staff to make multiple adjustments, reducing the workload.

[0022] When strong winds cause trees to sway, the trunk pulls the straightening rod 3 in the direction of tilting. This causes the straightening rod 3 to pull the rope 6 in the direction of tilting, making the locking ball 11 contact the rear end face of the locking pin 15 located inside the through hole 8. Since this end face is vertical, the locking ball 11 will not push the locking pin 15 upward, allowing the rope 6 to hold the trunk and prevent it from tilting again. At the same time, the two straightening rods 3 clamp the trunk from both sides, preventing it from swaying to either side in the direction of tilting. This provides support for the trunk during the straightening process, thus resisting the swaying caused by strong winds and reducing damage to the trees during the straightening process.

[0023] Specifically, in combination Figure 3 As shown, a pulley 16 is provided at both the front and rear ends of the locking block 7.

[0024] The two pulleys 16 make the axis of the pull rope 6 coincide with the axis of the through hole 8, so that the pull rope 6 and the locking ball 11 can easily enter the through hole 8, while the pulleys 16 reduce the resistance when the pull rope 6 slides.

[0025] Specifically, in combination Figure 3 As shown, flared openings are provided at both the front and rear ends of the through hole 8.

[0026] The ball 11 is further locked in place by the flared opening to facilitate its entry into the through hole 8.

[0027] Specifically, in combination Figure 3As shown, the slider 13 is fixedly connected to the lower end of the connecting rod 17, and the upper end of the connecting rod 17 passes through the locking block 7 and is fixedly connected to the pull ring 18.

[0028] By pulling the pull ring 18 upwards, the slider 13 is driven to slide upwards through the connecting rod 17, causing the end of the locking pin 15 to move out of the through hole 8, thus releasing the lock on the pull rope 6 and facilitating the installation of the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
