Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant cultivation technology, and in particular to a device for protecting and directional fixing of tree trunk sprouts. Background Technology
[0002] In the breeding of superior varieties of precious tree species, mature plants are often cut back to induce the sprouting of juvenile branches (sprouts) from the base, which serve as explants for asexual reproduction or tissue culture. These sprouts have the advantages of young physiological age and strong regeneration ability, and are key materials for the large-scale propagation of superior genotypes.
[0003] Currently, in the practice of rejuvenating precious tree species such as Pterocarya stenoptera, the tender shoots that sprout after coppicing generally face two major problems: First, the new shoots are weak and easily damaged by wind, animal grazing, human contact, or mechanical operations, resulting in an insufficient number of effective shoots; second, the natural growth direction of the sprouts is disordered, often creeping or tilting, making it difficult to form straight and robust high-quality explants, affecting the efficiency of subsequent tissue culture and transplant survival rate. According to feedback from forestry researchers, in Pterocarya stenoptera resource nurseries in Hainan, Guangdong, and other places, due to the lack of effective protection measures, the loss rate of sprouts in some experimental forests is as high as 40% or more. While existing simple shielding materials (such as plastic tubes and wire mesh) can provide some protection, they generally have problems such as being opaque, not breathable, unable to guide the growth direction, and difficult to adapt to the curved surface of the trunk, and cannot manage multiple buds at the same time.
[0004] Therefore, it is necessary to design a device for protecting and directionally fixing tree trunk sprouts. Utility Model Content
[0005] In order to overcome the shortcomings of existing technologies, such as the susceptibility of suckers to external damage and disordered growth direction, this utility model provides a trunk sucker protection and orientation fixing device.
[0006] The technical solution of this utility model is: a tree trunk sprout protection and orientation fixing device, including an elastic base, an adjusting screw, a fastening nut, a fixing seat, a transparent mesh cover, a cover mounting mechanism, a slide rail, a slider, a rotating rod, and a guide adjustment mechanism. There are two elastic bases, both of which are open annular. An adjusting screw is slidably inserted between the openings of the elastic bases. One end of the adjusting screw is threadedly connected to a fastening nut. A fixing seat is fixedly connected to the front side of each elastic base, and each fixing seat has a mounting hole. A transparent mesh cover is provided between the front sides of the two elastic bases. The transparent mesh cover is connected to the fixing seat through the cover mounting mechanism. Two slide rails are fixedly connected between the front sides of the two elastic bases. Multiple sliders are slidably connected to the upper part of the slide rails. A rotating rod is rotatably connected to the front side of each slider. A guide adjustment mechanism is provided on the free end of each rotating rod. Friction damping structures are provided between the sliders and the slide rails, and at the rotational connection points between the rotating rod and the sliders.
[0007] Furthermore, the protective cover installation mechanism includes mounting posts, clamping rods, and elastic elements. Mounting posts are fixedly connected to both the upper and lower sides of the transparent mesh protective cover. The mounting posts are inserted into the mounting holes on the corresponding fixing seats. The mounting posts on the upper side have a slot. The fixing seats on the upper side are slidably connected to the clamping rods. The clamping rods are inserted into the slots on the corresponding mounting posts, and elastic elements connect the clamping rods and the fixing seats.
[0008] Furthermore, the guiding adjustment mechanism includes a universal ball joint, a fastening bolt, a guide column, a guide ring, a second adjusting screw, and a second fastening nut. A universal ball joint is connected to the free end of each rotating rod, and a fastening bolt is threadedly connected to one side of each rotating rod. The fastening bolts abut against the corresponding universal ball joints, and a friction fit is provided between the contact surfaces of the two. A guide column is fixedly connected to the free end of each universal ball joint, and two mutually symmetrical guide rings are slidably connected to each guide column. An adjusting screw is slidably inserted between the two corresponding guide rings, and a second fastening nut is threadedly connected to one end of each adjusting screw.
[0009] Furthermore, it also includes signage, with signage attached to the outside of each slider. The signage is a pluggable information card and is made of one-piece molded transparent waterproof acrylic sheet.
[0010] Furthermore, it also includes a soft padding layer, with a soft padding layer provided on the inner side of the guide ring.
[0011] Furthermore, the elastic base is made of thermoplastic elastomer silicone material.
[0012] Beneficial effects: 1. This utility model sets up an adjustable clamping structure consisting of an elastic base, an adjusting screw, and a fastening nut, and uses a transparent mesh cover to form a closed protection for the sprouting area, effectively preventing wind damage, animal grazing, human collision, and mechanical damage, and significantly reducing the sprouting loss rate.
[0013] 2. This utility model arranges slide rails, sliders, rotating rods and guide adjustment mechanisms before the protective cover is installed, and uses universal ball joints with fastening bolts to achieve stepless three-dimensional angle adjustment. Then, the guide ring clamps the stem of the sprouting bud, so as to accurately guide the sprouting buds with messy natural growth direction and promote them to form straight and strong spikes.

Detailed Implementation
[0021] Example: A device for protecting and directionally fixing tree trunk sprouts, such as... Figures 1-6 As shown, the device includes an elastic base 1, an adjusting screw 2, a fastening nut 3, a fixing seat 4, a transparent mesh cover 41, a cover mounting mechanism, a slide rail 5, a slider 51, a rotating rod 52, and a guide adjustment mechanism. There are two elastic bases 1, both of which are open annular. The elastic bases 1 are made of thermoplastic elastomer silicone material to ensure a stable fit without damaging the bark. An adjusting screw 2 is slidably inserted between the openings of the elastic bases 1, and a fastening nut 3 is threaded onto one end of each adjusting screw 2. A fixing seat 4 is fixedly connected to the front of each elastic base 1, and each fixing seat 4 has a mounting hole. The front sides of the two elastic bases 1 are connected... A transparent mesh cover 41 is provided, which is connected to the fixed base 4 through a cover mounting mechanism. Two slide rails 5 are fixedly connected between the front sides of the two elastic bases 1. Multiple sliders 51 are slidably connected to the upper part of the slide rails 5. A rotating rod 52 is rotatably connected to the front side of each slider 51. A guide adjustment mechanism is provided on the free end of each rotating rod 52. A friction damping cooperation structure is provided between the slider 51 and the slide rail 5, and at the rotation connection between the rotating rod 52 and the slider 51, so that the sliding position of the slider 51 on the slide rail 5 and the rotation angle of the rotating rod 52 remain stable without external force, while they can move or rotate smoothly when a manual adjustment force is applied.
[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the protective cover mounting mechanism includes mounting posts 42, locking rods 43, and elastic elements 44. The transparent mesh protective cover 41 is fixedly connected to the mounting posts 42 on both the upper and lower sides. The mounting posts 42 are inserted into the mounting holes on the corresponding fixing seats 4. The mounting posts 42 on the upper side are provided with locking slots. The locking rods 43 are slidably connected to the inside of the fixing seats 4 on the upper side. The locking rods 43 are inserted into the locking slots on the corresponding mounting posts 42, and the locking rods 43 are connected to the fixing seats 4 by elastic elements 44.
[0023] like Figure 5 and Figure 6 As shown, the guiding adjustment mechanism includes a universal ball joint 53, a fastening bolt 54, a guide post 55, a guide ring 56, an adjusting screw 57, and a fastening nut 58. A universal ball joint 53 is connected to the free end of each rotating rod 52. A fastening bolt 54 is threadedly connected to one side of each rotating rod 52. Each fastening bolt 54 abuts against the corresponding universal ball joint 53, and a friction fit is provided between their contact surfaces. This allows the universal ball joint 53 to rotate freely when the fastening bolt 54 is loosened, and its spatial posture is locked by friction when the fastening bolt 54 is tightened, maintaining stability. A guide post 55 is fixedly connected to the free end of each universal ball joint 53. Two mutually symmetrical guide rings 56 are slidably connected to each guide post 55, and an adjusting screw 57 is slidably inserted between the corresponding two guide rings 56. A fastening nut 58 is threadedly connected to one end of each adjusting screw 57.
[0024] like Figure 5 and Figure 6 As shown, it also includes a signboard 6. The outer side of the slider 51 is connected to the signboard 6. The signboard 6 is a pluggable information card. The signboard 6 is made of one-piece molded transparent waterproof acrylic sheet, which has excellent outdoor weather resistance and anti-aging performance. It is convenient to clearly record key information such as variety name and processing time, and facilitates later tracking and management.
[0025] like Figure 5 As shown, it also includes a soft padding layer 7. The inner side of the guide ring 56 is provided with a soft padding layer 7, which can effectively disperse local pressure while providing the necessary restraint force and prevent pinching of delicate tissues.
[0026] In actual use of this device, firstly, the operator unscrews the fastening nut 3 and pulls out the adjusting screw 2. Then, the two elastic bases 1 are fastened to the designated position on the tree trunk x from the opening. Subsequently, the adjusting screw 2 is reinserted between the opening ends of the two elastic bases 1 and the fastening nut 3 is tightened. The clamping force applied by the fastening nut 3 makes the elastic base 1 fit tightly against the surface of the tree trunk x, achieving stability while avoiding mechanical damage to the bark.
[0027] Next, without the transparent mesh cover 41 installed, the internal guiding system is arranged first: the operator slides the slider 51 along the slide rail 5 to the vicinity of the horizontal position of the target sprout y, and then rotates the rotating rod 52 to initially adjust its spatial orientation. In order to facilitate clamping the tender bud, the second fastening nut 58 should be unscrewed and the second adjusting screw 57 should be pulled out, so that the two guide rings 56 are in a free open state. At this time, the guide rings 56 can be fastened to both sides of the stem of the sprout y from the side. After fastening, the second adjusting screw 57 is inserted back into the corresponding through hole of the guide ring 56, and the second fastening nut 58 is tightened at one end so that the guide ring 56 clamps the tender bud appropriately. The inner side of the guide ring 56 is provided with a soft buffer pad, which can effectively disperse local pressure while providing the necessary restraint force and prevent injury to the tender tissue.
[0028] During this process, the universal ball joint 53 plays a crucial role in spatial attitude adjustment. Before adjustment, the fastening bolt 54 is loosened to allow the universal ball joint 53 to rotate freely, thereby flexibly adjusting the pitch and deflection angles of the guide column 55 in three-dimensional space. This ensures that the guide ring 56 is precisely aligned with the natural growth axis of the sprout y. After the direction is set, the fastening bolt 54 is tightened to press the end of the universal ball joint 53. The friction between the contact surfaces is used to reliably lock the ball joint in the set attitude, achieving long-term stable maintenance of the guiding direction and avoiding deviation caused by wind vibration or growth disturbance.
[0029] After all the sprouts y have been precisely positioned, the transparent mesh cover 41 is installed last: The operator first pulls out the locking rod 43 to cover the entire cover around the installed guide mechanism and the sprouts y, and aligns the mounting post 42 at the bottom of the cover with the corresponding mounting hole on the fixing seat 4. After vertical insertion, the slot on the outer wall of the mounting post 42 is aligned with the locking rod 43. After releasing the locking rod 43, it automatically locks into the slot under the elastic force of the elastic element 44. When disassembly is required, simply pull out the locking rod 43 again to remove it from the slot, and the cover can be taken out. This achieves quick, tool-free locking and disassembly of the cover, taking into account both installation efficiency and structural reliability.
[0030] In addition, each slider 51 has an integrated label 6 on its outer side, made of one-piece molded transparent waterproof acrylic sheet, which has excellent outdoor weather resistance and anti-aging properties, making it easy to clearly record key information such as variety name and processing time. In summary, through the synergistic design of flexible clamping, multi-dimensional guidance and transparent protection, this device effectively solves the problems of easy damage to sprouts and disordered growth direction during the regeneration process of precious tree species, providing a straight, robust and high-quality source of explants for subsequent tissue culture.
