On the one hand, the throat clamp can adjust the diameter of the hoop ring as the trunk becomes thicker due to the growth of the seedlings, so as to prevent it from being embedded in the trunk and causing wound marks. On the other hand, the support mechanism can adjust the length of the bracket assembly and the inclination angle of the support as the trunk becomes taller due to the growth of the seedlings, so as to improve the firmness and stability of the seedling support. At the same time, a cavity for storing medicines and fertilizers is provided at the lower end of the inner part of the bracket assembly, so as to achieve the purpose of injecting medicines and fertilizers into the root system of the seedlings, thereby improving practicality and efficiency.

[0004] However, during use, due to the limited adjustment range of the hose clamp, when the tree grows beyond the adjustment range, the hose clamp will tighten the tree trunk again, making it inconvenient to remove it later. At the same time, the action position of the agent is fixed, resulting in uneven fertilization, which will lead to uneven growth of the seedlings. There are certain defects in use. Summary of the invention

[0005] The object of the present invention is to provide a seedling protection device for forestry afforestation land, so as to solve the problem raised in the above background technology that the adjustment range of the adjustment support mechanism of the seedling protection device currently on the market is limited, so that when the tree grows beyond the adjustment range, the trunk will be tightened again, and it will be inconvenient to disassemble it later. At the same time, the action position of the agent is fixed, resulting in uneven fertilization, which will lead to uneven growth of seedlings.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a forestry afforestation land seedling protection device, comprising a fixing piece fixedly installed on the outside of a seedling, an extension seat fixedly installed on the outside of the fixing piece, and a support assembly rotatably arranged on the outside of the extension seat, a connected cavity structure is provided between the fixing piece and the extension seat, and a telescopic rod is telescopically and slidably connected to the inside of the fixing piece, and a support plate is fixedly connected to one end of the telescopic rod close to the tree body, and a screw is threadedly connected to the extension seat, and the screw and the outside of the telescopic rod are elastically connected, and adjacent fixing pieces are fixedly connected by lock buckles, and an unlocking assembly is also arranged on the inside of the fixing piece;

[0007] The support assembly includes a rotating part rotatably installed on the outside of the extension seat, and the lower end of the rotating part is fixedly connected to the center rod, and the outer side of the center rod is sleeved with a fixing sleeve, and the lower end of the fixing sleeve is fixedly connected to the fixing column through a connecting sleeve, the lower end of the fixing column is rotatably connected to a positioning anchor, and an adjusting cylinder is elastically rotatably installed on the inner side of the connecting sleeve, and a spreading hole is opened on the adjusting cylinder for spreading fertilizer.

[0008] Preferably, the fixing piece is arranged in an arc structure, and a positioning hole is opened on the fixing piece, and the lock buckle is elastically rotatably connected to the fixing piece, and the lock buckle is elastically rotated and snapped into the positioning hole of the adjacent fixing piece to realize the assembly and fixation of each fixing piece.

[0009] By adopting the above technical solution, a plurality of fixing parts can be conveniently assembled on the outside of the tree body, so as to facilitate the subsequent support of the tree body.

[0010] Preferably, the screw rod is threadedly connected to the extension seat, and a slide groove is provided at one end of the screw rod close to the fixing member, and the slide groove inside the screw rod is telescopically connected to the telescopic rod, and a first spring is connected between the screw rod and the telescopic rod.

[0011] By adopting the above technical solution, the rotating screw can drive the telescopic rod to push the support plate to fit the outside of the tree body, thereby supporting the tree body. The elastic telescopic characteristics of the telescopic rod can prevent the tree body from being limited and squeezed by the support plate during growth, thereby preventing the normal growth of the tree from being affected.

[0012] Preferably, the unlocking assembly includes a slider slidably mounted on the inner side of the fixing member, and a second spring is connected between the slider and the fixing member, and the diameter of the telescopic rod at one end close to the support plate gradually increases, and when the telescopic rod is contracted, its end pushes the slider to slide on the inner side of the fixing member, and at the same time, the slider pushes the lock buckle to rotate during the sliding process to ensure that the lock buckle is disengaged from the positioning hole.

[0013] By adopting the above technical solution, the growth of the tree causes the support plate to drive the telescopic rod to be telescopically adjusted, and the telescopic rod can push the lock to rotate and disengage from the positioning hole, thereby releasing the assembly of the fixing parts without the need for subsequent manual disassembly. At the same time, it prevents the tree from growing beyond the moving range of the support plate and causing damage to the tree.

[0014] Preferably, the support components are arranged at equal angles, and the positioning anchors at the lower ends of the support components are fixedly inserted into the soil to achieve multi-directional support for the trees.

[0015] By adopting the above technical solution, the support assembly can provide multi-directional support to the tree, thereby ensuring that the sapling grows stably and vertically and avoids toppling over due to strong winds.

[0016] Preferably, the central rod, the fixing sleeve and the adjusting tube are coaxially arranged, and the central rod, the fixing sleeve and the adjusting tube all constitute a telescopic structure.

[0017] By adopting the above technical solution, as the tree grows, the fixing part will gradually move away from the ground along with the tree. At this time, the central rod will be telescopically adjusted together with the fixing sleeve and the adjusting tube to ensure stable support.

[0019] By adopting the above technical solution, when the center rod and the adjusting tube are telescopically adjusted, the ball will slide along the first guide groove, thereby driving the adjusting tube to rotate, and when the ball moves to the top of the first guide groove, the adjusting tube will elastically rotate and reset, so that the ball continues to slide along the second guide groove arranged circumferentially, to realize the reciprocating rotation of the adjusting tube, and the second guide groove arranged circumferentially can prevent the center rod from excessively descending and contracting to affect the supporting effect, and when the tree body is bent by external force, the center rod will contract and adjust with the adjusting tube, so that the adjusting tube rotates elastically, and at this time the center rod can provide buffer support for the tree body to prevent the tree body from breaking at the supporting point due to excessive external force.

[0020] Preferably, a fertilizer storage cavity is provided on the inner side of the fixed sleeve, and granular fertilizer is stored in the fertilizer storage cavity, and a first through hole communicating with the fertilizer storage cavity is provided at the lower end of the fixed sleeve, a temporary storage cavity is provided on the inner side of the lower part of the adjusting cylinder, and a second through hole communicating with the temporary storage cavity is provided at the upper end of the adjusting cylinder, and the second through hole is connected to the first through hole after the adjusting cylinder rotates.

[0021] By adopting the above technical solution, when the ball rotates along the first guide groove, the adjusting cylinder can be driven to rotate. When the second through hole on the adjusting cylinder is connected to the first through hole on the fixed sleeve, part of the fertilizer in the fertilizer storage cavity will fall into the temporary storage cavity through the first through hole and the second through hole.

[0022] Preferably, an opening structure is provided on the connecting sleeve, and the opening on the connecting sleeve faces the tree, and when the first through hole and the second through hole are connected, the connecting sleeve blocks and blocks the material spreading hole.

[0023] By adopting the above technical solution, when fertilizer enters the temporary storage cavity, the spreading hole is blocked by the connecting sleeve to prevent the fertilizer from falling. When the adjusting cylinder is elastically rotated and reset, the spreading hole passes through the opening of the connecting sleeve and can evenly spread the fertilizer near the tree.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the forestry afforestation land seedling protection device can provide stable buffer support for the tree body, and can be automatically dismantled after the tree grows to avoid restricting the further growth of the tree trunk, and can automatically and evenly fertilize the tree during its growth. The specific contents are as follows;

[0025] 1. A telescopic rod, a support plate and a screw are provided. By rotating the screw, the position of the telescopic rod and the support plate can be adjusted, so that multiple support plates can fit and support trees of different sizes. The telescopic rod and the screw can be elastically adjusted to provide space for the growth of the tree trunk and avoid the occurrence of strangulation marks on the tree trunk.

[0026] 2. A lock, a telescopic rod and a slider are provided. As the tree grows, the telescopic rod is pushed by the support plate to be telescopically adjusted, so that the variable diameter part of the telescopic rod contacts and pushes the slider to slide elastically, so that the slider pushes the lock to rotate elastically, thereby releasing the splicing between adjacent fixings, without the need for subsequent manual removal, and avoiding affecting the continued normal growth of the tree;

[0027] 3. A center rod, a fixed sleeve and an adjusting cylinder are provided. When the growth of the tree drives the center rod to move upward, the center rod, the fixed sleeve and the adjusting cylinder are telescopically adjusted, and the ball slides along the first guide groove and the second guide groove to drive the adjusting cylinder to rotate elastically. When the tree is tilted by external force, the center rod is forced to move downward, so that the ball slides along the first guide groove. At this time, the adjusting cylinder rotates elastically, thereby achieving buffering support for the tree body and preventing the tree body from breaking at the supporting point. The second guide groove can limit the downward movement distance of the center rod to prevent the equipment from losing its supporting function.

[0028] 4. A fixed sleeve and an adjusting cylinder are provided. As the center rod moves upward, it can drive the adjusting cylinder to rotate elastically, so that the fertilizer storage chamber and the temporary storage chamber are connected through the first through hole and the second through hole, so as to realize the addition of fertilizer to the temporary storage chamber. When the ball moves to the second guide groove, the adjusting cylinder will rotate elastically and reset, so that the adjusting cylinder can use the spreading hole to evenly spread the fertilizer to the soil near the tree roots, so as to realize uniform and effective fertilization and ensure that the trees can grow evenly.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 5 As shown, the existing forestry afforestation land seedling protection device cannot be automatically disassembled under the action of tree growth when in use, so that the tree growth is easily restricted. In order to solve this technical problem, this embodiment discloses the following technical content;

[0041] A forestry afforestation land seedling protection device, comprising a fixing member 1 spliced ​​and fixedly installed on the outside of a seedling, an extension seat 2 is fixedly installed on the outside of the fixing member 1, and a support assembly 3 is rotatably arranged on the outside of the extension seat 2, a connected cavity structure is opened between the fixing member 1 and the extension seat 2, and a telescopic rod 6 is telescopically and slidably connected to the inside of the fixing member 1, and a support plate 7 is fixedly connected to one end of the telescopic rod 6 close to the tree body, and a screw rod 8 is threadedly connected to the extension seat 2, and the screw rod 8 and the outside of the telescopic rod 6 are elastically connected, and adjacent fixing members 1 are fixedly connected by a lock buckle 4, and an unlocking assembly is also arranged on the inside of the fixing member 1;

[0042] The fixing member 1 is arranged in an arc structure, and a positioning hole 5 is opened on the fixing member 1, and the lock buckle 4 is elastically rotatably connected to the fixing member 1, and the lock buckle 4 is elastically rotated and snapped into the positioning hole 5 of the adjacent fixing member 1 to realize the assembly and fixation of each fixing member 1.

[0043] The screw rod 8 is threadedly connected to the extension seat 2 , and a slide groove is provided at one end of the screw rod 8 close to the fixing member 1 , and the slide groove inside the screw rod 8 is telescopically connected to the telescopic rod 6 , and a first spring 9 is connected between the screw rod 8 and the telescopic rod 6 .

[0044] The unlocking assembly includes a slider 10 slidably installed on the inner side of the fixing member 1, and a second spring 11 is connected between the slider 10 and the fixing member 1. The diameter of the telescopic rod 6 at one end close to the support plate 7 gradually increases, and when the telescopic rod 6 contracts, its end pushes the slider 10 to slide on the inner side of the fixing member 1. At the same time, the slider 10 pushes the lock buckle 4 to rotate during the sliding process to ensure that the lock buckle 4 is disengaged from the positioning hole 5.

[0045] By adopting the above technical scheme, when it is necessary to support the tree, the four fixing parts 1 are fitted and sleeved on the outside of the trunk support point, and the lock buckle 4 is rotated at the same time, so that the lock buckle 4 is stuck in the positioning hole 5 of the adjacent fixing part 1 to realize the assembly of the device, and then the screw rod 8 is rotated to make the screw rod 8 drive the support plate 7 to fit the trunk support point through the telescopic rod 6. The screw rod 8 is further rotated to adjust the supporting strength of the support plate 7. As the tree grows, the support plate 7 will drive the telescopic rod 6 to perform elastic telescopic adjustment, thereby providing space for the growth of the tree and avoiding marks on the surface of the tree. As the tree grows, the diameter reduction part of the telescopic rod 6 will gradually fit and push the slider 10 to slide elastically on the inner side of the fixing part 1, so that the slider 10 fits and pushes the lock buckle 4 to rotate elastically, so that the lock buckle 4 is separated from the positioning hole 5, and then the assembly of the fixing part 1 is released, avoiding restricting the subsequent growth of the tree, and also eliminating the step of subsequent staff to disassemble the device.

[0046] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing forestry afforestation land seedling protection device is inconvenient to apply fertilizer evenly during use. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 3 and Figure 6-Figure 9 As shown;

[0047] The support assembly 3 includes a rotating member 12 rotatably mounted on the outside of the extension seat 2, and the lower end of the rotating member 12 is fixedly connected to the center rod 13, and the outer side of the center rod 13 is sleeved with a fixing sleeve 14, and the lower end of the fixing sleeve 14 is fixedly connected to a fixing column 16 through a connecting sleeve 15, and the lower end of the fixing column 16 is rotatably connected to a positioning anchor 17, and an adjusting cylinder 18 is elastically rotatably mounted on the inner side of the connecting sleeve 15, and a spreading hole 1804 is opened on the adjusting cylinder 18 for spreading fertilizer.

[0048] The support components 3 are tilted at equal angles, and the positioning anchors 17 at the lower ends of the support components 3 are fixedly inserted into the soil to achieve multi-directional support for the tree.

[0049] The central rod 13 , the fixing sleeve 14 and the adjusting tube 18 are coaxially arranged, and the central rod 13 , the fixing sleeve 14 and the adjusting tube 18 all constitute a telescopic structure.

[0050] A first guide groove 1301 and a second guide groove 1302 are alternately provided on the center rod 13 from bottom to top, and the first guide groove 1301 is spirally arranged, and the second guide groove 1302 is a circumferential arc groove on the center rod 13, and both ends of the second guide groove 1302 are respectively connected to the lower end of the first guide groove 1301 above it and the upper end of the first guide groove 1301 below the second guide groove 1302, and a ball 1802 is embedded in the inner wall of the upper end of the adjusting cylinder 18, and the ball 1802 rolls along the first guide groove 1301 and the second guide groove 1302.

[0051] A fertilizer storage chamber 1401 is provided on the inner side of the fixed sleeve 14, and granular fertilizer is stored in the fertilizer storage chamber 1401, and a first through hole 1402 communicating with the fertilizer storage chamber 1401 is provided on the lower end of the fixed sleeve 14, a temporary storage chamber 1801 is provided on the inner side of the lower part of the adjusting cylinder 18, and a second through hole 1803 communicating with the temporary storage chamber 1801 is provided on the upper end of the adjusting cylinder 18, and the second through hole 1803 is connected to the first through hole 1402 after the adjusting cylinder 18 is rotated.

[0053] By adopting the above technical solution, after the positioning anchor 17 is inserted and fixed on the ground, the positioning anchor 17 can be used to support and protect the tree trunk. As the tree grows, it will drive the central rod 13 to move upward through the fixing member 1, so that the ball 1802 on the inner wall of the adjusting cylinder 18 slides along the first guide groove 1301, thereby driving the adjusting cylinder 18 to rotate and adjust. When the spreading hole 1804 on the adjusting cylinder 18 is covered and blocked by the connecting sleeve 15, the first through hole 1402 and the second through hole 1803 will be connected, so that part of the fertilizer in the fertilizer storage chamber 1401 will pass through The first through hole 1402 and the second through hole 1803 fall into the temporary storage chamber 1801. As the adjusting cylinder 18 rotates, when the ball 1802 moves to the end of the first guide groove 1301, the adjusting cylinder 18 will elastically rotate and reset, so that the ball 1802 slides along the second guide groove 1302. At this time, the adjusting cylinder 18 will drive the spreading hole 1804 to pass through the opening of the connecting sleeve 15, and spread the fertilizer evenly to the root part of the tree through the action of centrifugal force, so as to achieve uniform fertilization of the trees, and the second guide groove 1302 can prevent the center rod 13 from moving downward excessively, thereby ensuring the supporting function of the device.
