DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0024] Please refer to Figures 1-10 To solve the problem that most of the existing supporting devices do not consider that trees will grow with time, the static support structure does not match the dynamic demand of plant growth, and the support only relies on the support of the rod on the ground, lacking effective fixation, the spiral shaft 202 is arranged to match the growth of trees, the extension rod 201 is elongated with the growth of trees, and the continuous and effective support is formed, the clamping jaw 301 connected by the torsional spring can adapt to trees with different diameters and can also adapt to the thickening of the growth of trees, the vertical knife 502 and the inclined knife 503 are arranged to fix the underframe 1 on the ground all the time, so that long-term effective support is realized, the growth of trees is ensured, and the problem of repeatedly planting and slowing down the sand control efficiency is avoided. The utility model provides a technical scheme: a sand land vegetation ecological restoration device, which comprises an underframe 1 and a support rod 2, one end of the extension rod 201 is slidably connected to the upper end of the support rod 2, the other end of the extension rod 201 is hingedly connected to a support rod 3, the support rod 3 clamps the trees, the lower end of the support rod 2 is hingedly connected to the underframe 1, and the underframe 1 is fixed in the land; the clamping jaw 301 is hingedly connected to the two sides of the support rod 3 through a torsional spring, and the clamping jaw 301 clamps the trees. After planting the trees, according to the thickness of the trees, the size of the sand and other factors, it is determined that several support rods 2 are needed to support, then the plurality of support rods 3 are supported on the trees, the underframe 1 is fixed on the ground, and the support is completed; when the trees grow, the trees drive the support rod 2 to change the angle with the underframe 1, so that the support rod 2 is elongated to continue to form effective support for the trees; when large sand is encountered, if the trees have a tendency to lean towards one of the support rods 2, the support rod 2 will also be elongated, thereby helping the trees resist the sand and ensuring their growth.
[0025] To adapt to the growth of trees, the shaft of the articulated connection between the support rod 2 and the chassis 1 is fixedly connected to the chassis 1 and rotatably connected to the support rod 2. A large bevel gear 403 is fixedly connected to the shaft. The large bevel gear 403 is arranged in the support rod 2 and meshes with a small bevel gear 402. The small bevel gear 402 is rotatably connected in the support rod 2. A screw shaft 202 is rotatably connected in the support rod 2. The screw shaft 202 is provided with a screw groove. A screw block 203 is slidably connected in the screw groove. The screw block 203 is fixed in an extension rod 201. A linkage shaft 401 is also arranged in the support rod 2. The linkage shaft 401 is provided with splines on both sides. One end of the linkage shaft 401 is rotatably connected to a push rod 4. The other end of the push rod 4 extends out of the support rod 2. The push rod 4 is positioned relative to the support rod 2 by a ball spring to prevent the linkage shaft 401 from being inserted into the small bevel gear 402 too early. The splines on the upper part of the linkage shaft 401 are always slidably connected to the screw shaft 202. The splines on the lower part of the linkage shaft 401 can be inserted into the small bevel gear 402. The small bevel gear 402 is fixedly connected to a hollow shaft, which is rotatably connected to a support bracket. The support bracket is fixedly connected to the support rod 2. The screw shaft 202 is rotatably connected to a screw base 204, which is fixedly connected to the support rod 2. When in use, after the chassis 1 is fixed, the push rod 4 is pulled down to move the linkage shaft 401 downward, so that the splines on the linkage shaft 401 are inserted into the small bevel gear 402. The splines between the linkage shaft 401 and the small bevel gear 402 are arranged in multiple positions, and inclined surfaces are arranged at positions close to each other to ensure insertion. The arrangement of multiple splines ensures that the splines on the linkage shaft 401 are timely aligned with positions in the small bevel gear 402, which only causes slight rotation of the linkage shaft 401 and does not affect the support of the tree. After the insertion is completed, when the tree grows, the support rod 3 moves, the support rod 3 swings the support rod 2, the support rod 2 swings the screw shaft 202, the screw shaft 202 rotates the small bevel gear 402 around the axis of the large bevel gear 403. In this process, the small bevel gear 402 rotates, the small bevel gear 402 rotates the linkage shaft 401, the linkage shaft 401 rotates the screw shaft 202, the rotation of the screw shaft 202 moves the screw block 203, and the screw block 203 slides the extension rod 201 out of the support rod 2, thereby adapting to the growth of the tree.
[0026] In order to realize the fixing of the chassis 1, the button 5 is slidably connected on the chassis 1, the ball spring is used for positioning between the button 5 and the chassis 1, the button 5 is avoided from sliding off, the vertical knife 502 is fixedly connected below the button 5, the vertical knife 502 is slidably connected in the chassis 1, and the vertical knife 502 can be inserted into the land from the chassis 1. The push block 501 is fixedly connected below the button 5, the push block 501 is fixedly connected below the vertical knife 502, the inclined surface is arranged on the push block 501, one end of the inclined knife 503 is slidably connected on the inclined surface, the inclined knife 503 is slidably connected in the chassis 1, and the inclined knife 503 can be inserted into the land from the chassis 1. When using, after the position is determined, the button 5 is pressed, the button 5 drives the push block 501 to move downwards, the push block 501 drives the vertical knife 502 to move downwards and pushes the inclined knife 503 to be inclined and extended, so that the vertical knife 502 and the inclined knife 503 are inserted into the ground, and the fixing of the chassis 1 is realized.
