Description

Technical Field

[0001] This utility model relates to the technical field of tree seedling root protection devices, and in particular to tree seedling root protection devices for forest farms. Background Technology

[0002] Protecting the root system of seedlings is crucial for improving the survival rate of afforestation and promoting healthy tree growth. The root system is the core organ for seedlings to absorb water and nutrients. Especially during transplanting and short-term storage, if the soil ball attached to the roots becomes loose, it can lead to root dehydration, breakage, or infection, severely affecting the recovery and growth of the seedlings. Effectively protecting the root system not only maintains its physiological integrity and reduces transplant stress, but also accelerates the recovery process after planting and promotes new root formation.

[0003] In existing technologies, plastic bags are commonly used to protect the root system of seedlings. However, using plastic bags to protect the root system of seedlings has many disadvantages: plastic bags have low strength and are easily damaged during transportation or storage due to scratches or trampling, causing the soil ball to be exposed and dry out and crack. They also cannot effectively prevent rodents from gnawing on the roots, which often damages the root system. Furthermore, their structure lacks support and is easily deformed and compressed by external forces, affecting aeration and potentially causing root rot. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a tree seedling root protection device for forest farms, comprising protective plates 11 that can be connected end-to-end to form a protected area. An insert plate 21 is installed on the side of the protective plate 11 away from the protected area. An anti-climbing post 22 is provided on the insert plate 21 to prevent rodents from climbing. The height of the end of the anti-climbing post 22 away from the insert plate 21 is lower than the height of the section of the anti-climbing post 22 closest to the insert plate 21. Adjacent protective plates 11 are connected by a hinge. The protected area is used to place the root system of the seedling containing a soil ball. A base plate 12 is also provided on the side of the protective plate 11 away from the protected area to increase the stability of the protection device. By connecting multiple protective plates 11 end-to-end to form a ring-shaped protected area, the soil ball of the seedling root can be effectively wrapped, preventing the soil ball from loosening due to collisions during short-term storage. The hinged splicing method allows multiple protective plates 11 to be connected together, and the size of the protected area can be adjusted as needed. The insert plate 21 and the anti-climbing post 22 are detachable and can be selected whether to retain them after the seedling is planted, while also preventing obstruction when splicing the protective plates 11. The anti-climb post 22 adopts a lower inclined structure at the end away from the insertion plate 21, forming an inclined post that is not conducive to rat climbing, effectively preventing them from climbing along the device to the base of the seedling and causing gnawing damage, thus improving the survival rate of the seedling. The base plate 12 can significantly enhance the stability of the entire protective device and reduce the possibility of it tipping over under the action of wind or external forces.

[0024] Please see Figure 1-5A further embodiment of this solution is as follows: the top of the protective plate 11 is provided with a slot 111 for inserting the insert plate 21, and the side of the protective plate 11 away from the protected area is provided with a clearance opening 112 to avoid the anti-climbing post 22. The slot 111 allows the insert plate 21 to be quickly installed onto the protective plate 11 by vertical insertion. The connection method is simple and reliable, and disassembly and assembly can be completed without tools, facilitating maintenance or replacement of damaged insert plates 21. The clearance opening 112 provides space for the anti-climbing post 22, ensuring that the anti-climbing post 22 will not interfere with the body of the protective plate 11 after the insert plate 21 is inserted.

[0025] Please see Figure 1-5 A further solution based on this embodiment is as follows: the anti-climb post 22 has a threaded surface, and the anti-climb post 22 is threadedly connected to the insert plate 21. Threading adhesive is applied to the threaded surface, and a cone 221 is provided on the side of the anti-climb post 22 away from the protective plate 11. The threaded connection ensures a firm and reliable connection between the anti-climb post 22 and the insert plate 21, which can withstand a certain amount of external impact and is not easily detached, ensuring the durability of the anti-climb function. The use of threading adhesive further enhances the sealing and anti-loosening performance of the connection, preventing the threads from loosening due to vibration. The cone 221 is located at the outer end of the anti-climb post 22, which not only serves as an anti-climb device but also deters mice tactilely, further improving the anti-climbing effect.

[0026] Please see Figure 1-4 A further solution based on this embodiment is as follows: the top of the insert plate 21 is provided with a pull block 211 for installing or removing the insert plate 21. The pull block 211 provides the operator with a clear point of force application, making it easy to pinch with fingers or use simple tools for insertion and removal operations, significantly improving the ease of installation and removal of the insert plate 21 and reducing the possibility of the cone 221 piercing or scratching the skin.

[0027] Please see Figure 1-4 A further embodiment of this design includes a protective plate 11 comprising a first clamping block 113 and a second clamping block 115 on the left side, and a protrusion 114 on the right side. The distance between the first clamping block 113 and the second clamping block 115 is the same as the height of the protrusion 114. The design of the first clamping block 113, the protrusion 114, and the second clamping block 115 facilitates increased stability between adjacent protective plates 11 and reduces the possibility of vertical swaying.

[0028] Please see Figure 2-5A further solution based on this embodiment is as follows: the top of the protrusion 114 is provided with a through insertion hole 1141, the pivot pin 3 includes a rotating post 31 for passing through the insertion hole 1141, the first clamping block 113 is provided with a first clearance hole for avoiding the rotating post 31, and the second clamping block 115 is provided with a second clearance hole for avoiding the rotating post 31. By inserting the rotating post 31 into the insertion hole 1141, the first clearance hole, and the second clearance hole, it is possible for adjacent protective plates 11 to rotate.

[0029] Please see Figure 2-5 A further solution based on this embodiment is as follows: a limiting circular plate 32 is provided at the bottom of the rotating column 31, and a circular groove 1151 for accommodating the limiting circular plate 32 is provided at the bottom of the second clamping block 115. An annular groove 311 for sleeved retaining spring is provided on the rotating column 31. When the limiting circular plate 32 is in contact with the circular groove 1151, the retaining spring is in contact with the protective plate 11. The axial positioning of the rotating pin 3 is achieved through the cooperation between the limiting circular plate 32 and the retaining spring on the circular groove 1151, preventing it from accidentally falling off during use. This structure is easy to disassemble and assemble; the rotating pin 3 can be removed simply by using retaining spring pliers to remove the retaining spring, making disassembly and assembly convenient.

[0030] Please see Figure 2-4 A further solution based on this embodiment is as follows: a reinforcing plate 121 is connected to both the protective plate 11 and the base plate 12. The base plate 12 has mounting holes 120 for inserting expansion bolts. The reinforcing plate 121 connects the protective plate 11 and the base plate 12, significantly enhancing the structural strength at the connection point. The mounting holes 120 can be used to insert expansion bolts, further anchoring the base plate 12 to the ground. This is particularly suitable for sloping terrain, areas with strong winds, or scenarios requiring long-term fixation, greatly improving the stability and anti-tipping ability of the protective device. It is necessary to ensure that the ground surface to which the base plate 12 is in contact is a concrete surface.

[0031] Working principle: Based on the size of the root ball of the sapling to be protected and the requirements of the on-site storage or planting environment, the operator can connect multiple protective plates 11 end to end through a hinged structure to form a ring-shaped protective area. Specifically, the protrusion 114 on the right side of one protective plate 11 is inserted between the first clamping block 113 and the second clamping block 115 on the left side of the adjacent protective plate 11, and the insertion hole 1141 on the protrusion 114 is aligned with the first clearance hole on the first clamping block 113 and the second clearance hole on the second clamping block 115. Then, the rotating pin 3's rotating post 31 is passed through the second clearance hole, the insertion hole 1141, and the first clearance hole in sequence until it reaches the limit. The circular plate 32 is embedded in the circular groove 1151 at the bottom of the second clamping block 115. Then, the retaining spring is inserted into the annular groove 311 on the rotating column 31 and fits against the protective plate 11, thereby achieving axial fixation of the pivot pin 3 and completing the hinged connection between adjacent protective plates 11. This connection method allows each protective plate 11 to rotate relative to the pivot pin 3, making it easy to adjust the size and shape of the protected area to meet the storage needs of different numbers or specifications of seedling roots. After multiple protective plates 11 are spliced ​​together, they are enclosed around the roots of the seedling containing the soil ball to form a stable annular protective space, effectively preventing the soil ball from being damaged by external collisions during short-term storage in the forest. Loosen the insert plate 21; then, vertically insert the insert plate 21 into the slot 111 at the top of the protective plate 11 through its bottom plug end. The anti-climb post 22 on the insert plate 21 then enters the clearance opening 112 to avoid structural interference. After installation, the anti-climb post 22 is tilted, with the end away from the insert plate 21 being lower than the end near the insert plate 21, forming an obstacle that is not conducive to rat climbing. At the same time, the cone 221 set at the outer end of the anti-climb post 22 has a visual and tactile deterrent effect on rats. Combined with the sturdy structure of the threaded connection and the application of thread sealant, it ensures that the anti-climb post 22 works stably for a long time and effectively prevents rats from climbing along the device to the base of the seedling and causing gnawing damage. If the insert plate 21 needs to be removed, simply pinch the pull block 211 with your hand or a tool and pull it upwards. The disassembly and assembly are convenient and safe. In situations where the stability of the overall device needs to be enhanced, expansion bolts can be inserted through the mounting holes 120 on the base plate 12 to firmly anchor the base plate 12 to the concrete ground. At the same time, the presence of the reinforcing plate 121 significantly improves the strength of the connection between the protective plate 11 and the base plate 12, preventing the connection from breaking or deforming due to external forces. This is especially suitable for sloping terrain, areas with strong winds, or scenarios requiring long-term fixed protection. Rats usually cannot bear the stinging pain of the cone 221 and will forcibly push the insert plate 21 out of the slot 111.

[0032] 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
