Description

Technical Field

[0001] This utility model relates to the field of seedling protection technology, specifically to a seedling protection device. Background Technology

[0002] Paris polyphylla is a plant with important medicinal value. It prefers shady and moist environments and generally grows in valleys, under broad-leaved forests, in thickets, along streams, and near rocks. Chinese Patent Publication No. CN 210695246U discloses a seedling protection device for intercropping Paris polyphylla in forests, including a front support frame and a rear support frame. A first shade net is fixedly installed on the front support frame and the rear support frame near the middle position. A horizontal plate is placed between the upper surfaces of the front support frame and the rear support frame. A locking block is fixedly installed on the lower surface of the horizontal plate near the front and rear edges. The locking block is engaged with the top of the front support frame and the rear support frame.

[0003] The above-mentioned technical solution, a seedling protection device for intercropping Paris polyphylla under forests, provides protection through a shade net. However, the second shade net is limited by the weight of a counterweight, and it still sways when the wind is strong, affecting the protective effect. Furthermore, locking the height position with the first locking bolt requires auxiliary tools, making the operation relatively cumbersome.

[0004] Therefore, a seedling protection device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a seedling protection device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A seedling protection device includes a protective frame with nail posts, a fixing plate at the top of the protective frame, a roller rotatably mounted on the fixing plate, a shade net mounted on the roller, a torsion handle on one side of the roller, a fixing mechanism for fixing the shade net on the protective frame, a movable rod inside the protective frame, an adjusting rod inserted into the movable rod, an adjusting mechanism for height adjustment on the adjusting rod, and a clamping mechanism for holding and straightening the seedling.

[0008] Furthermore, the fixing mechanism includes a U-shaped plate, which is installed on the surface of the protective frame. A cylinder is slidably installed on the U-shaped plate. A spring is sleeved on the outer wall of the cylinder. A pressure plate is installed on the surface of the cylinder and is inserted into the shading net and the protective frame, and is in contact with the shading net. A pull plate is installed on the surface of the cylinder.

[0009] Furthermore, the number of cylinders and springs is set to multiple, and they are distributed at equal intervals.

[0010] Furthermore, the adjustment mechanism includes a sliding member that is slidably sleeved on a moving rod. Multiple adjustment slots are formed on the surface of the moving rod. A connecting plate is mounted on the surface of the sliding member. A limit post is slidably mounted on the connecting plate and is inserted into the sliding member and one of the adjustment slots. A spring is sleeved on the outer wall of the limit post, and a pulling member is mounted on the surface of the limit post.

[0011] Furthermore, the clamping mechanism includes a connecting shell, which is mounted on the surface of the sliding member. A bidirectional lead screw is rotatably mounted inside the connecting shell. Two long rods are threaded onto the outer wall of the bidirectional lead screw. One end of the bidirectional lead screw extends outside the connecting shell, and a torsion handle is mounted on the surface of the extended end of the bidirectional lead screw.

[0012] Furthermore, clamping blocks are installed on the surfaces of both long rods, and protective pads are provided on the surfaces of both clamping blocks.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a spring, a cylinder, and a pressure plate. By rotating the torsion handle, the shaft roller rotates, releasing the shading net and blocking the opening of the protective frame. Pulling the pull plate causes the cylinder to slide on the U-shaped plate, while the pressure plate moves accordingly, disengaging from the protective frame and compressing the spring. This aligns the shading net with the pressure plate. The pull plate can then be released, and the pressure plate returns to its original position under the restoring force of the spring. The pressure plate is then inserted into the shading net and the protective frame, pressing the shading net onto the frame, thus fixing the shading net and preventing it from blowing in the wind and affecting its protective effect.

[0015] This invention utilizes a combination of spring two, a bidirectional lead screw, and clamping blocks. By pulling the pulling element, the limiting post is disengaged from its original adjustment groove. It can then be pulled upwards, causing the sliding element to slide on the moving rod, and the connecting shell to move accordingly. When the connecting shell reaches the designated height, the pulling element can be released. Under the restoring force of spring two, the limiting post returns to its original position and is inserted into the corresponding adjustment groove, locking the position of the connecting shell. Rotating the torsion handle two rotates the bidirectional lead screw, causing the two long rods to move closer together, and the two clamping blocks to move accordingly. The protective pad contacts the seedling's branches, clamping and straightening it. This allows for adjustment and straightening of the seedling according to its height, making the operation simple and highly practical. Attached Figure Description

[0026] like Figure 1-2 , Figure 4 As shown, a seedling protection device includes a protective frame 1, with nail posts 2 on the protective frame 1, a fixing plate 3 on the top of the protective frame 1, a roller 4 rotatably mounted on the fixing plate 3, a shade net 5 mounted on the roller 4, a torsion handle 6 on one side of the roller 4, a fixing mechanism 7 for fixing the shade net 5 on the protective frame 1, a moving rod 9 inside the protective frame 1, an adjusting rod 8 inserted into the moving rod 9, an adjusting mechanism 10 for height adjustment on the adjusting rod 8, and a clamping mechanism 11 for clamping and straightening the seedling on the adjusting mechanism 10. In this embodiment, it is noted that a counterweight is provided at the bottom of the shade net 5, as can be seen from the nail posts 2. In use, the protective frame 1 is placed on the ground, and... The nail post 2 is inserted into the soil layer. According to the position of the seedling, the position of the adjusting mechanism 10 and the clamping mechanism 11 can be adjusted by the cooperation of the adjusting rod 8 and the moving rod 9. According to the height of the seedling, the height of the clamping mechanism 11 can be adjusted by the adjusting mechanism 10. The clamping mechanism 11 clamps and fixes the seedling branches and straightens them. Then, by turning the torsion handle 6, the shaft roller 4 is rotated to loosen the shade net 5 and cover the opening of the protective frame 1. The fixing mechanism 7 fixes the shade net 5 to prevent it from blowing in the wind and affecting its shading and protection. Thus, it can be adjusted according to the height of the seedling, clamped and straightened, and the shade net 5 can be fixed to prevent it from blowing in the wind and affecting the shading and protection effect. It is simple to operate and highly practical.

[0027] like Figure 1-3As shown, the fixing mechanism 7 includes a U-shaped plate 701, which is mounted on the surface of the protective frame 1. A cylinder 702 is slidably mounted on the U-shaped plate 701. A spring 703 is sleeved on the outer wall of the cylinder 702. A pressure plate 705 is mounted on the surface of the cylinder 702, and the pressure plate 705 is inserted into the shade net 5 and the protective frame 1, and in contact with the shade net 5. A pull plate 704 is mounted on the surface of the cylinder 702. In this embodiment, through... Pulling the pull plate 704 causes the cylinder 702 to slide on the U-shaped plate 701, and the pressure plate 705 moves accordingly, disengaging from the protective frame 1 and compressing the spring 703. When the shade net 5 corresponds to the pressure plate 705, the pull plate 704 can be released. Under the restoring force of the spring 703, the pressure plate 705 is reset. The pressure plate 705 is inserted into the shade net 5 and the protective frame 1, pressing the shade net 5 onto the protective frame 1, thereby fixing the shade net 5.

[0028] like Figure 3 As shown, the number of cylinders 702 and springs 703 is set to multiple and is distributed at equal intervals. In this embodiment, the stability of fixing the shade net 5 is improved by setting the number of cylinders 702 and springs 703.

[0029] like Figure 4-5 As shown, the adjusting mechanism 10 includes a sliding member 1005, which is slidably sleeved on the moving rod 9. Multiple adjusting grooves 1006 are formed on the surface of the moving rod 9. A connecting plate 1001 is mounted on the surface of the sliding member 1005. A limiting post 1002 is slidably mounted on the connecting plate 1001, and the limiting post 1002 is inserted into the sliding member 1005 and one of the adjusting grooves 1006. A spring 1003 is sleeved on the outer wall of the limiting post 1002, and a pulling member 1 is mounted on the surface of the limiting post 1002. 004. In this embodiment, by pulling the pulling member 1004, the limiting post 1002 is disengaged from the original adjustment groove 1006. At this time, it can be pulled upward to make the sliding member 1005 slide on the moving rod 9. When the sliding member 1005 reaches the specified height, the pulling member 1004 can be released. Under the reset force of the spring 1003, the limiting post 1002 is reset and inserted into the corresponding adjustment groove 1006 to lock the position of the sliding member 1005, thereby facilitating the height adjustment of the sliding member 1005.

[0030] like Figure 4-5As shown, the clamping mechanism 11 includes a connecting shell 1101, which is mounted on the surface of the sliding member 1005. A bidirectional lead screw 1102 is rotatably mounted inside the connecting shell 1101. Two long rods 1103 are threadedly mounted on the outer wall of the bidirectional lead screw 1102. One end of the bidirectional lead screw 1102 extends outside the connecting shell 1101, and a second torsion handle 1105 is mounted on the surface of the extended end of the bidirectional lead screw 1102. In this embodiment, by rotating the second torsion handle 1105, the bidirectional lead screw 1102 is driven to rotate, causing the two long rods 1103 to slide inside the connecting shell 1101, moving towards or away from each other, thereby adjusting the distance between the two long rods 1103.

[0031] like Figure 5 As shown, clamping blocks 1104 are installed on the surfaces of the two long rods 1103, and protective pads are provided on the surfaces of the two clamping blocks 1104. In this embodiment, when the two long rods 1103 move closer to each other, the two clamping blocks 1104 move accordingly, and the protective pads come into contact with the branches of the seedlings, clamping and straightening them.

[0032] In summary, it is explained that the bottom of the shade net 5 is equipped with a counterweight, which can be seen from the thumbtack post 2. During use, the protective frame 1 is placed on the ground, and the thumbtack post 2 is inserted into the soil layer. Depending on the position of the seedling, the positions of the adjusting mechanism 10 and the clamping mechanism 11 can be adjusted by the coordination of the adjusting rod 8 and the moving rod 9. Furthermore, depending on the height of the seedling, the height of the clamping mechanism 11 can be adjusted by the adjusting mechanism 10. The clamping mechanism 11 clamps and fixes the seedling branches, straightening them. Then, by rotating the torsion handle 6, the shaft roller 4 is rotated, loosening the shade net 5 and adjusting the protective frame. The opening of the shading frame 1 is blocked by a fixing mechanism 7, which secures the shading net 5 to prevent it from swaying in the wind and affecting its protective effect. This allows for adjustment based on the seedling height, clamping and straightening the net, and securing it to prevent it from swaying and affecting the protective effect. The operation is simple and highly practical. By pulling the pull plate 704, the cylinder 702 slides on the U-shaped plate 701, and the pressure plate 705 moves accordingly, disengaging from the protective frame 1 and compressing the spring 703. When the shading net 5 aligns with the pressure plate 705, the pull plate 704 can be released, and the spring 703... Under the reset force, the pressure plate 705 is reset. The pressure plate 705 is inserted into the shade net 5 and the protective frame 1, and presses the shade net 5 onto the protective frame 1, thereby fixing the shade net 5. The stability of fixing the shade net 5 is improved by setting the number of cylinders 702 and springs 703. By pulling the pulling member 1004, the limiting post 1002 is driven out of the original adjusting groove 1006. At this time, it can be pulled upward to make the sliding member 1005 slide on the moving rod 9. When the sliding member 1005 reaches the specified height, the pulling member 1004 can be released, and the spring 703 will return to its original position. Under the elastic force, the limiting post 1002 is reset and inserted into the corresponding adjustment groove 1006 to lock the position of the sliding member 1005, thereby facilitating the height adjustment of the sliding member 1005. By rotating the second torsion handle 1105, the bidirectional lead screw 1102 is driven to rotate, causing the two long rods 1103 to slide in the connecting shell 1101, with a movement trajectory that moves closer or further away from each other, thereby adjusting the distance between the two long rods 1103. When the two long rods 1103 move closer to each other, the two clamping blocks 1104 move accordingly, and the protective pad contacts the branches of the seedling, clamping and straightening it.
