Description

Technical Field

[0001] The utility model relates to the technical field of forestry planting, and specifically relates to a tree supporting device for forestry planting. Background Technique

[0002] During the process of forestry planting, in order to ensure the normal growth of trees, it is necessary to set up brackets around the trees to support the trees and prevent the growth direction of the trees from deviating. For example, the patent document with the publication number CN214316480U in the prior art provides a tree supporting device for forestry planting; this device clamps and positions the trees through two symmetrically arranged semi-circular plates. However, the semi-circular plates of this device are fixedly arranged, and there are significant differences in the outer diameters of the tree trunks in forestry planting, which makes it difficult for such fixedly arranged semi-circular plates to clamp and position trees with various diameters, and there are obviously large defects. Therefore, we have proposed a tree supporting device for forestry planting. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tree supporting device for forestry planting to solve the problems raised in the above background technique.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Example 1, please refer to Figures 1-6 , the present invention provides a technical solution: a tree support device for forestry planting, including two semi-circular positioning frames 1 hinged to each other. Arc-shaped cavities 11 are opened in the two semi-circular positioning frames 1 on both sides. A plurality of movable plates 12 are slidably installed in the arc-shaped cavities 11. A positioning plate 13 is inserted into the movable plate 12. A threaded sleeve 15 is fixedly installed on the outer end face of the positioning plate 13. A threaded rod 16 threadedly engaged with the threaded sleeve 15 is rotatably installed in the movable plate 12. Positioning tooth grooves 3 are opened above and below the arc-shaped cavity 11. Positioning tooth blocks 32 engaged with the positioning tooth grooves 3 are arranged on both the upper and lower sides of the movable plate 12.

[0024] Working principle: When in use, through the hinge cooperation between the two semi-circular positioning frames 1, the device is installed on the periphery of the tree, and the joint of the two semi-circular positioning frames 1 is fixed by bolts. Then, according to the shape of the tree, the movable plate 12 can be adjusted to an appropriate position in the arc-shaped cavity 11. Then, the threaded rod 16 is rotated outside the movable plate 12. Through the threaded cooperation between the threaded rod 16 and the threaded sleeve 15, the positioning plate 13 can be driven to move inwards to fit the periphery of the tree, so that the tree can be positioned within the two semi-circular positioning frames 1;

[0025] Among them, when the positioning plate 13 contacts the periphery of the tree, the positioning plate 13 will push the positioning tooth block 32 to move outwards, so that the positioning tooth block 32 is inserted into the positioning tooth groove 3, so that the movable plate 12 can be positioned within the semi-circular positioning frame 1, avoiding loosening of the movable plate 12 and the positioning plate 13.

[0026] Embodiment 2. A limit sleeve 14 is fixedly installed on the inner end face of the movable plate 12. A threaded sleeve 15 is arranged inside the limit sleeve 14. Limit chutes 141 are opened on both sides of the inner cavity of the limit sleeve 14. A limit slide rail 151 that is inserted and matched with the limit chute 141 is fixedly installed on the periphery of the threaded sleeve 15. A through cavity 2 is opened inside the threaded rod 16. A positioning sleeve 21 that is matched with the through cavity 2 is fixedly installed on the outer end face of the positioning plate 13. An activity seat 22 is arranged on the outer side of the threaded rod 16. A positioning plug rod 23 that is inserted into the positioning sleeve 21 is fixedly installed on the inner end face of the activity seat 22. A first limit jack 24 is opened on the periphery of the through cavity 2. A first limit plug rod 25 that is inserted into the first limit jack 24 is fixedly installed on the inner end face of the activity seat 22. A connecting seat 26 is fixedly installed on the inner side of the first limit plug rod 25. A first spring 27 that is sleeved on the periphery of the first limit plug rod 25 is fixedly installed between the connecting seat 26 and the first limit jack 24.

[0027] Specifically, the limit sleeve 14 is provided. Through the insertion and matching between the limit chute 141 and the limit slide rail 151, the movement direction of the threaded sleeve 15 can be restricted inside the limit sleeve 14, so that the rotating threaded rod 16 can drive the positioning plate 13 to move in and out through the thread matching between it and the threaded sleeve 15.

[0028] When the threaded rod 16 needs to be rotated, the positioning plug rod 23 can be pulled outwards through the activity seat 22, so that the positioning plug rod 23 is separated from the positioning sleeve 21, and the limit effect between the threaded rod 16 and the threaded sleeve 15 is released, thus facilitating the rotation of the threaded rod 16. After the rotation of the threaded rod 16 is completed, the activity seat 22 is released. Under the action of the first spring 27 restoring deformation, the activity seat 22 can be driven to reset, so that the positioning plug rod 23 is re-inserted into the positioning sleeve 21. With the matching effect between the first limit plug rod 25 and the first limit jack 24, the positioning between the threaded rod 16 and the threaded sleeve 15 can be carried out, the rotation of the threaded rod 16 is restricted, and the stability of the positioning plate 13 is improved.

[0029] Embodiment 3. Activity cavities 31 that are matched with the positioning tooth grooves 3 are opened on the upper and lower sides of the movable plate 12. A positioning tooth block 32 is slidably installed inside the activity cavity 31. A dial plate 36 is fixedly installed on the periphery of the positioning tooth block 32. A second limit plug rod 33 is fixedly installed inside the activity cavity 31. A second limit jack 34 that is inserted and matched with the second limit plug rod 33 is opened on the inner end face of the positioning tooth block 32. A second spring 35 that is sleeved on the periphery of the second limit plug rod 33 is fixedly installed between the positioning tooth block 32 and the activity cavity 31.

[0030] Specifically, when the number of positioning plates 13 needs to be increased according to the shape of the tree, the positioning tooth block 32 can be pressed inward in the movable cavity 31 through the dial plate 36, and the positioning tooth block 32 can be adjusted into the movable cavity 31, so that the movable plate 12 can be installed into the arc-shaped cavity 11. Finally, the dial plate 36 is released. Under the action of the restoration of the second spring 35 and in cooperation with the insertion effect between the second limit insertion rod 33 and the second limit insertion hole 34, the positioning tooth block 32 can be inserted into the positioning tooth groove 3 to complete the installation of the movable plate 12. On the contrary, the movable plate 12 can be disassembled in the arc-shaped cavity 11.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
