Description

Technical Field

[0001] This utility model relates to the field of afforestation and seedling protection technology, and in particular to a seedling protection device suitable for plateau afforestation in special terrain. Background Technology

[0002] In plateau ecological restoration and afforestation projects, the special terrain and harsh environment pose a dual challenge to the survival of seedlings, becoming a key bottleneck restricting the effectiveness of greening. Plateau regions encompass complex landforms such as cliffs and steep slopes of the Loess Plateau and gullies of the Qinghai-Tibet Plateau. These areas generally suffer from rugged terrain, steep slopes, and extremely poor surface flatness. At the same time, they are accompanied by extreme climatic characteristics such as high altitude, strong ultraviolet radiation, large temperature differences between day and night, scarce rainfall, and infertile soil, resulting in poor root development and weak resistance of seedlings, which are easily affected by external factors such as strong winds and landslides.

[0003] The existing fixed support structure for seedling protection adopts a rigid support design, which cannot be adjusted according to the flatness of rugged ground such as steep slopes and cliffs. It can only provide stable support on flat land. In areas with significant elevation differences, the support points are prone to being suspended, causing the seedlings to tilt or even fall over. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seedling protection device suitable for high-altitude afforestation in special terrain.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seedling protection device suitable for plateau afforestation in special terrain, comprising:

[0006] Retaining rings are used to support components;

[0007] The secondary ring is rotatably connected to the fixed ring via a hinge, and one end of the secondary ring is threaded with a bolt, and one end of the bolt is threaded into a threaded hole at one end of the fixed ring.

[0008] The support mechanism includes a secondary support leg arranged on a fixing ring for providing support for the sapling; the support mechanism is also provided with a locking component, including a wedge-shaped locking post arranged on one side of the secondary support leg for fixing the adjusted secondary support leg;

[0009] A fixing structure used to secure seedlings to a fixing ring.

[0010] As a further description of the above technical solution: the support mechanism also includes:

[0011] The main support leg is fixedly arranged at the bottom of the fixing ring to accommodate the auxiliary support leg, and the auxiliary support leg is slidably connected to the main support leg, with a wedge-shaped locking post slidably connected to one side of the main support leg.

[0012] The compression spring is fixedly mounted at the upper end of the auxiliary outrigger and at the lower end inside the main outrigger.

[0013] As a further description of the above technical solution: the main support leg is provided in three sets, and is evenly arranged in a triangular inclined shape at the bottom of the fixing ring.

[0014] As a further description of the above technical solution: the locking component also includes:

[0015] The slot is located on one side of the auxiliary leg, and one end of the wedge-shaped locking post is engaged in the slot.

[0016] The return spring has one end fixedly attached to the wedge-shaped locking post and the other end fixedly attached to the inner wall of the main support leg.

[0017] The circular ring is used to move the wedge-shaped locking pin.

[0018] A limiting groove is provided on one side of the main support leg to limit the movement of the ring, and the ring is slidably connected to the limiting groove.

[0019] As a further description of the above technical solution: the upper end of the wedge-shaped locking post is triangular, and the lower end of the wedge-shaped locking post is L-shaped.

[0020] As a further description of the above technical solution: the fixing structure includes:

[0021] A threaded rod, threadedly connected to a retaining ring;

[0022] The arc-shaped block is used to fix the sapling trunk, and one end of the threaded rod is rotatably set in a T-shaped groove opened on one side of the arc-shaped block.

[0023] As a further description of the above technical solution: the threaded rod is provided in three sets, two sets of the threaded rod are provided on the fixed ring, and one set of the threaded rod is threadedly connected to the secondary ring.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, by adaptively adjusting to special terrain, pressing down on the ring causes the wedge-shaped locking post to disengage from the slot. After pressing down on the fixing ring, the three sets of auxiliary legs can extend and retract autonomously according to the flatness of the ground under the action of the compression spring. When contacting higher ground, the auxiliary legs compress the spring and retract into the main legs. After all three sets of auxiliary legs are in contact with the ground, the reset spring pushes the wedge-shaped locking post into the slot to complete the fixation. With the rivet limit at one end of the auxiliary legs, precise adaptation to different terrain levels is achieved, which greatly improves the adaptability to special plateau terrain and the stability of seedling support.

[0026] 2. In this utility model, the safety of the seedling is ensured by a multi-protective structure of "ring fixing + triangular support + three-point clamping". First, the seedling is quickly fitted with the opening and closing structure of the secondary ring and the fixed ring and locked with bolts. Then, the three sets of main support legs and secondary support legs arranged in a triangular inclination form a stable support. Finally, the three sets of threaded rods are turned to drive the arc-shaped blocks to clamp the trunk from three sides. The triangular support and fixing structure can effectively resist the impact of external factors on the seedling and prevent it from falling over. At the same time, the rubber layer of the arc-shaped blocks and the additional gauze and cotton quilts can reduce the damage to the trunk and significantly improve the survival rate of the seedling.

[0042] It should be noted that the lower end of the auxiliary support leg 402 is provided with a rubber layer to increase the friction of the auxiliary support leg 402, and a rivet is provided through one end of the auxiliary support leg 402 to fix the positioning of the auxiliary support leg 402.

[0043] As a preferred embodiment, the main support leg 401 is provided in three sets, and is evenly arranged in a triangular inclined shape at the bottom of the fixing ring 1.

[0044] In a preferred embodiment, the locking component further includes: a slot 404, which is provided on one side of the auxiliary support leg 402, and one end of the wedge-shaped locking post 405 is engaged in the slot 404; a return spring 406, one end of which is fixedly disposed on the wedge-shaped locking post 405, and the other end of which is fixedly disposed on the inner wall of the main support leg 401; a ring 407, which is used to drive the wedge-shaped locking post 405 to move; and a limiting groove 408, which is provided on one side of the main support leg 401, which is used to limit the ring 407, and the ring 407 is slidably connected to the limiting groove 408.

[0045] The circular ring 407 is not completely circular, and the upper ends of the three sets of wedge-shaped locking posts 405 are all located below the circular ring 407.

[0046] In a preferred embodiment, the upper end of the wedge-shaped locking post 405 is triangular, and the lower end of the wedge-shaped locking post 405 is L-shaped.

[0047] Example 2:

[0048] Based on Example 1, in order to further improve the stability of the seedling, a fixing structure is provided on the fixing ring 1.

[0049] As a preferred implementation, a fixing structure is used to fix the seedling to the fixing ring 1.

[0050] As a preferred embodiment, the fixing structure includes: a threaded rod 501, which is threadedly connected to the fixing ring 1; and an arc-shaped block 502, which is used to fix the sapling trunk, and one end of the threaded rod 501 is rotatably disposed in a T-shaped groove opened on one side of the arc-shaped block 502.

[0051] It should be noted that one side of the arc-shaped block 502 is provided with a rubber layer to prevent the arc-shaped block 502 from damaging the surface of the seedling during fixing. When fixing the seedling, gauze or cotton quilts can also be placed at the contact points between the three sets of arc-shaped blocks 502 and the seedling for protection.

[0052] In a preferred embodiment, the threaded rod 501 is provided in three sets: two sets of threaded rods 501 are provided on the fixed ring 1, and one set of threaded rods 501 is threadedly connected to the secondary ring 2.

[0053] Working principle: When in use, first turn the bolt 3 to rotate. The bolt 3 moves to one side through the threaded hole of the auxiliary ring 2 and the fixed ring 1. When one end of the bolt 3 is disengaged from the threaded hole, turn the auxiliary ring 2 to rotate on the fixed ring 1 through the hinge. Then, place the device on the sapling through the gap between the auxiliary ring 2 and the fixed ring 1. At this time, the sapling is located in the middle of the fixed ring 1. Then, reset the auxiliary ring 2 on the fixed ring 1 and turn the bolt 3 in the opposite direction to fix it in the threaded hole of the fixed ring 1.

[0054] Then, press down on the ring 407 to slide it on the limiting groove 408. Simultaneously, the ring 407 presses down on the three sets of wedge-shaped locking pins 405. The triangular inclined surface at the upper end of the wedge-shaped locking pins 405 causes them to slide to one side on the main support leg 401, compressing the return spring 406. When one end of the wedge-shaped locking pin 405 disengages from the locking groove 404, the fixing ring 1 is pressed down. The fixing ring 1 drives the three sets of main support legs 401 to move. The main support legs 401 rebound through the compression spring 403, keeping the three sets of auxiliary support legs 402 always in a downward direction. In any one of the three sets... When the three sets of auxiliary legs 402 are in contact with the ground at a higher elevation, they slide into the main support leg 401 by compressing the compression spring 403. When all three sets of auxiliary legs 402 are in contact with the ground due to the flatness of the ground, the ring 407 is released. The three sets of return springs 406 rebound and cause the three sets of wedge-shaped locking posts 405 to engage with the corresponding locking slots 404 to fix the auxiliary legs 402. The auxiliary legs 402 are also limited by the rivets at one end of the auxiliary legs 402. This allows for adaptive adjustment according to the levelness of different terrains, improving the stability of the support and protection for the seedlings.

[0055] Then, the three sets of threaded rods 501 are screwed in sequence. The threaded rods 501 are connected to the fixed ring 1 and the secondary ring 2 by threads, which drives the arc-shaped block 502 to move to one side. When the arc-shaped block 502 makes lateral contact with the three sides of the trunk, the trunk is fixed. The triangular arrangement of the three sets of main support legs 401 and the three sets of arc-shaped blocks 502 prevents the seedling from tipping over due to external factors after planting, thus improving the survival rate.

[0056] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
