Description

Technical Field

[0001] The invention relates to the technical field of seedling planting, and in particular to a seedling planting support device for forestry greening. Background Art

[0002] With the development of economy and the acceleration of urbanization, people are paying more and more attention to the ecological environment. As an important means to improve the urban environment and enhance the city's image, forestry greening plays a vital role in modern society. In the early stage of planting, the seedlings are easily affected by the external environment because their root system is not fully developed and the soil fixation ability is weak. For example, strong winds, heavy rains and other natural factors can cause the seedlings to tilt, fall over or even die. Therefore, after the seedlings are planted, support devices are needed to support the seedlings to prevent them from tilting and falling over due to external forces.

[0003] The supporting device generally includes a fixing belt and a supporting rod. After planting the seedlings, the fixing belt is put on the trunk of the seedlings, and then the supporting rods are fixed to the bottom surface and the fixing belt respectively, so that the supporting force of the four supporting rods can provide support for the seedlings, preventing the seedlings from tilting and falling over due to external forces.

[0004] For example, in the prior art, the patent with the authorization announcement number CN114258819B discloses a seedling transplanting support device that is convenient to adjust, including a plurality of support rods arranged on one side of the seedlings, the outer wall of the support rods is slidably sleeved with a sleeve, and one side wall of the sleeve is threadedly connected with a support bolt, one end of the support bolt passes through the sleeve and abuts against the support rod, and one side wall of the sleeve is fixedly connected with a rotating assembly, one end of the rotating assembly is fixedly connected with a clamping block, and one side wall of the clamping block is provided with a cavity. The above device is provided by setting a connector, a pull rope and a ground nail, etc., and when in use, one end of the pull rope can be fixed with the connector, and then the ground nail can be directly pulled, so that the ground nail pulls the pull rope to fix the clamping block and the seedling, which is convenient and quick; and the cooperation between the ground nail and the pull rope can further increase the stability of the seedlings supported by the device and enhance the wind resistance of the seedlings.

[0005] However, the above-mentioned support device has certain defects when in use; when the support device is used to support the seedlings, the trunk of the seedlings will develop rapidly during the growth stage of the seedlings. Since the existing support device cannot adjust the size of the fixing belt, as the seedlings grow and develop, the fixing belt will be embedded in the trunk, hindering the transportation of nutrients and water, and even causing wounds to the seedlings, becoming an invasion route for pathogens and pests, affecting the healthy growth and survival rate of the seedlings. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a seedling planting support device for forestry greening, so that the support device can adjust the size of the fixed structure.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figures 1 to 11 A seedling planting support device for forestry greening includes multiple support rods 1 and a fixing belt 2. The fixing belt 2 is connected to each support rod 1 through a connecting assembly. The outer wall of the fixing belt 2 is connected to multiple fixing assemblies. Each fixing assembly is located between two adjacent support rods 1. The fixing assembly includes a connecting block 4, a threaded rod 6, a rotating block 8 and a clamping plate 9. The connecting block 4 is fixedly connected to the outer wall of the fixing belt 2. A threaded groove 5 is provided in the connecting block 4. The threaded rod 6 is threadedly connected in the threaded groove 5. A rotating groove 7 is provided at one end of the threaded rod 6 located on the inner side of the fixing belt 2. A rotating block 8 is rotatably connected in the rotating groove 7. The end of the rotating block 8 away from the threaded rod 6 is fixedly connected to the clamping plate 9, and the side of the clamping plate 9 away from the threaded rod 6 is connected to a filling assembly.

[0022] The seedling planting support device for forestry greening of the present invention, before planting the seedlings, first put the fixing belt 2 on the outside of the seedlings from above or below the seedlings, after the seedlings are planted, move the fixing belt 2 to a suitable height, and then rotate the threaded rod 6 to move the threaded rod 6 into the inside of the fixing belt 2, at this time, the threaded rod 6 will push the clamping plate 9 to move until all the clamping plates 9 are in contact with the bark of the seedlings, then insert the support rod 1 into the ground, use the connecting assembly to connect the support rod 1 with the fixing belt 2, and the installation of the support device and the planting of the seedlings can be completed; after the seedlings grow for a period of time, the threaded rod 6 can be used to move each clamping plate 9 outward a small section to prevent the clamping plate 9 from affecting the growth of the main trunk of the seedlings; By utilizing the mutual cooperation between the splint 9 and the threaded rod 6, the splint 9 can adjust the fixing range according to the growth of the seedlings, and flexibly adjust the degree of fit with the main trunk of the seedlings, so that the fixing structure of the support device can automatically adapt as the seedlings grow, avoiding the problem of embedding in the tree trunk that may be caused by traditional support devices, preventing the splint 9 from hindering the transportation of nutrients and water, and preventing the splint 9 from causing wounds to the seedlings, thereby reducing the invasion pathways of pathogens and pests, contributing to the healthy growth of the seedlings, and improving the survival rate of the seedlings; the rotating block 8 and the rotating groove 7 can rotate the threaded rod 6 without driving the splint 9 to rotate, but only driving the splint 9 to move forward and backward, avoiding unnecessary damage to the seedling epidermis caused by the rotation of the splint 9, reducing potential risks such as scratches or strangulation, and helping to promote the healthy growth and development of the seedlings.

[0023] As a preferred technical solution of the present invention, one end of the threaded rod 6 away from the clamping plate 9 is fixedly connected to a handle 10 .

[0024] Specifically, the design of the handle 10 enables the operator to apply force more conveniently when rotating the threaded rod 6, thereby making it easier to adjust the position of the splint 9. This setting simplifies the operating steps, improves work efficiency, and can also provide a comfortable grip and anti-slip performance. The handle 10 reduces the risk of accidental injury to the operator due to slippage or hand fatigue during operation, enhances the operator's experience, and enables the operator to maintain better comfort and satisfaction when operating for a long time or frequently adjusting the position of the splint 9.

[0025] As a preferred technical solution of the present invention, the filling component includes a silicone pad 11 and a connecting belt 12. The silicone pad 11 is fixedly connected to the side of the splint 9 away from the threaded rod 6. Two connecting belts 12 are fixedly connected between the two ends of the silicone pad 11. The connecting belt 12 is fixedly connected to the side of the splint 9 close to the threaded rod 6.

[0026] Specifically, after the supporting device is installed on the seedling, the silicone pad 11 will be clamped on the outside of the seedling trunk by the splint 9. As the seedling continues to grow and the trunk continues to thicken, the silicone pad 11 will undergo drastic deformation under the squeezing of the trunk. When the operator observes this drastic deformation, it means that it has approached or reached its deformation limit, and the threaded rod 6 can be used to move the splint 9 outward, and then the silicone pad 11 can be replaced, and then the silicone pad 11 can be re-attached to the trunk; the setting of the silicone pad 11 provides a buffer between the splint 9 and the trunk to avoid the hard squeezing of the splint 9 during the thickening of the trunk, thereby protecting the healthy growth of the seedling trunk and preventing the splint 9 from damaging the seedling; the silicone pad 11 and the connecting belt 12 are fixedly connected to the splint 9 by an adhesive. Compared with mechanical connection, the adhesive connection can reduce mechanical damage to the splint 9, maintain its integrity and functionality, and increase the service life of the splint 9.

[0027] As a preferred technical solution of the present invention, the connecting assembly includes a fixed block 13, a rotating shaft 14, a moving block 15, a connecting rod 16, a connecting sleeve 17, a threaded column 19 and a clamping ring 29. The outer wall of the fixing belt 2 is fixedly connected with multiple fixed blocks 13 corresponding to the position of the support rod 1, the fixed block 13 is fixedly connected with the rotating shaft 14 on the side away from the fixing belt 2, the outer wall of the rotating shaft 14 is rotatably connected with the moving block 15, the bottom of the moving block 15 is fixedly connected with the connecting rod 16, the outer wall of the bottom end of the connecting rod 16 is fixedly connected with the clamping ring 29, the clamping ring 29 is rotatably connected to the inner wall at the top of the connecting sleeve 17, a moving groove 18 is opened on the inner wall at the bottom of the connecting sleeve 17, the inner wall of the moving groove 18 is threadedly connected with a threaded column 19, and an installation assembly is connected between the bottom end of the threaded column 19 and the top of the support rod 1.

[0028] Specifically, during the growth of the seedlings, although the support device will support the seedlings, the seedlings may still grow obliquely due to natural factors (such as strong winds causing the support device to fail) or the growth habits of the seedlings themselves; when the operator observes that the seedlings are growing obliquely, the operator can rotate the connecting sleeve 17 away from the inclination direction of the seedlings. As the connecting sleeve 17 rotates, under the action of the threads of the movable groove 18 and the outer wall of the threaded column 19, the threaded column 19 will gradually retract into the connecting sleeve 17. At this time, as the threaded column 19 is tightened, a pulling force away from the inclination direction of the seedlings will be provided to the fixing belt 2 through the connecting sleeve 17 and the connecting rod 16. As the seedlings grow subsequently, this pulling force will continue to fine-tune the seedlings to ensure that they remain in the correct growth direction and maintain the vertical growth of the seedlings, which is conducive to the healthy growth of the seedlings and the future beauty of their appearance.

[0029] As a preferred technical solution of the present invention, the installation assembly includes an insertion rod 3, a fixing sleeve 20, bolts 22 and a fixing plate 30. The bottom end of the threaded column 19 is fixedly connected to the fixing sleeve 20, and a slot 21 is provided on the bottom surface of the fixing sleeve 20. The top of the support rod 1 is fixedly connected to the insertion rod 3, and the insertion rod 3 is slidably connected to the slot 21. The outer wall of the fixing sleeve 20 is fixedly connected to the fixing plate 30, and a plurality of bolts 22 are fixedly connected to the surface of the fixing plate 30. The outer wall of the insertion rod 3 is provided with fixing holes 23 corresponding to the positions of the bolts 22.

[0030] Specifically, when installing the support device, first insert the rod 3 into the slot 21, then use the bolt 22 to fix the rod 3 and the fixing sleeve 20, and then fix the support rod 1 to the ground to complete the installation and fixation of the support device.

[0031] As a preferred technical solution of the present invention, the outer wall of the connecting sleeve 17 is provided with anti-slip grooves 24 .

[0032] As a preferred technical solution of the present invention, a plurality of rotating rods 25 are fixedly connected to the outer wall of the connecting sleeve 17 .

[0033] Specifically, when using the connecting sleeve 17, first hold the connecting sleeve 17 so that the palm of the hand fits the anti-slip groove 24, then quickly rotate the connecting sleeve 17 to achieve coarse adjustment of the connecting sleeve 17, and then use the rotating rod 25 to fine-tune the connecting sleeve 17 by turning the rotating rod 25 to ensure that the seedlings receive enough pulling force to return to the correct position; the anti-slip groove 24 increases the operator's grip friction when rotating the connecting sleeve 17 to prevent operational errors or safety accidents caused by hand slippage; the rotating rod 25 provides the user with a more precise and convenient operating method for fine-tuning the connecting sleeve 17, which brings convenience to the operator.

[0034] As a preferred technical solution of the present invention, an isolation sleeve 26 is fixedly connected between the bottom of the connecting sleeve 17 and the fixing sleeve 20 , and the threaded column 19 is located in the isolation sleeve 26 .

[0035] Specifically, the isolation sleeve 26 can provide rain and corrosion protection for the threads on the threaded column 19, help keep the threaded column 19 clean and dry, reduce thread damage or loosening caused by corrosion, and ensure that the threaded column 19 can still operate stably after the support device is used in the field for a long time, provide sufficient support force for the fixing belt 2, and provide stable pulling force for the seedlings, thereby extending the service life of the threaded column 19, reducing the maintenance and replacement costs caused by corrosion, and ensuring the stable operation of the support device after long-term use in the field.

[0036] As a preferred technical solution of the present invention, a fixing rod 27 is fixedly connected to the bottom of the connecting rod 16 , and a fixing groove 28 corresponding to the position of the fixing rod 27 is opened on the surface of the threaded column 19 .

[0037] As a preferred technical solution of the present invention, the cross-sections of the fixing rod 27 and the fixing groove 28 are cross-shaped.

[0038] Specifically, the design of the fixing rod 27 and the fixing groove 28 can increase the connection strength between the connecting rod 16, the connecting sleeve 17 and the threaded column 19, improve their stability, and ensure that the connecting rod 16, the connecting sleeve 17 and the threaded column 19 remain in the same straight line, thereby providing sufficient support force for the fixing belt 2 and sufficient pulling force for the seedlings; the cross-shaped design of the cross section of the fixing rod 27 and the fixing groove 28 can increase the connection area, improve the connection strength, and effectively prevent the fixing rod 27 from bending or rotating when subjected to force, thereby ensuring the stability and reliability of the connection.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
