Example 1

[0027] A tree support device for municipal gardens, such as Figure 1 and Figure 2 As shown, it includes a supporting leg 1, a supporting ring 11, a supporting mechanism 2 and a fixing mechanism 3. There are two supporting legs 1, and the two supporting legs 1 are symmetrically arranged on the left and right. The upper parts of the two supporting legs 1 are connected to form a ring. The top of the upper supporting leg 1 is fixedly connected with a supporting ring 11. The supporting leg 1 is provided with a supporting mechanism 2, and the supporting leg 1 is provided with a fixing mechanism 3.

[0028] like Figure 1 and Figure 3 As shown, the support mechanism 2 includes a first fixed rod 21, a first tension spring 22, a first arc-shaped plate 23 and a fixed block 24. Fixed blocks 24 are welded on both the front and rear sides of the upper part of the support leg 1. The first fixed rods 21 are fixedly connected to the fixed blocks 24. The first fixed rods 21 are fixedly connected to the adjacent support legs 1. There are two first arc-shaped plates 23. One first arc-shaped plate 23 is slidably connected between the upper first fixed rods 21, and the other first arc-shaped plate 23 is slidably connected between the lower first fixed rods 21. The first arc-shaped plates 23 are bent in a direction away from each other. The first tension spring 22 is wound around the first fixed rod 21. The inner and outer ends of the first tension spring 22 are respectively fixedly connected to the first arc-shaped plate 23 and the fixed block 24.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the fixing mechanism 3 includes a telescopic rod 31, a first pressure spring 32, a second arc plate 33, a reinforcing plate 34 and a first fixed plate 35. The first fixed plate 35 is welded to the lower part of the supporting leg 1, and the upper part of the first fixed plate 35 is fixedly connected to the telescopic rod 31. The side of the telescopic rod 31 that is close to each other is set as a telescopic part, and the side of the telescopic rod 31 that is away from each other is set as a fixed part. The telescopic part of the telescopic rod 31 is fixedly connected to the second arc plate 33. The material of the outside of the first arc plate 23 and the second arc plate 33 is set as rubber material to avoid damage to the trunk of the tree. The telescopic part of the telescopic rod 31 is wound with a first pressure spring 32, and the inner and outer ends of the first pressure spring 32 are respectively fixedly connected to the second arc plate 33 and the fixed part of the telescopic rod 31. The first fixed plate 35 is slidably connected to the reinforcing plate 34, and the upper part of the reinforcing plate 34 is tilted inward and downward. The second arc plate 33 contacts the upper part of the adjacent reinforcing plate 34, and the lower part of the reinforcing plate 34 is provided with spikes.

[0030] In the process of municipal garden construction, when trees need to be planted, the municipal garden tree support device can be used. People first place the municipal garden tree support device at a designated location, so that the spikes of the reinforcing plate 34 are inserted into the ground, and the centers of the middle parts of the two first arc-shaped plates 23, the centers of the middle parts of the two second arc-shaped plates 33, and the locations where the trees are planted on the ground are in a vertical line, and then the first arc-shaped plates 23 are pulled away from each other, the first tension spring 22 is stretched, and the second arc-shaped plates 33 are pulled away from each other, the first pressure spring 32 is compressed, and then Then, the trunk of the tree is passed vertically through the middle of the support ring 11, the middle of the two first curved plates 23, and the middle of the two second curved plates 33, and the tree is planted in the soil. Then, the first curved plate 23 and the second curved plate 33 are loosened, and the elastic force of the first tension spring 22 causes the first curved plate 23 to move inward to clamp and fix the upper part of the tree trunk, and the elastic force of the first pressure spring 32 causes the second curved plate 33 to move inward to clamp and fix the lower part of the tree trunk. In this way, multiple parts of the tree can be supported, and the first curved plate 23 and the second curved plate 33 have a larger supporting surface for the tree trunk, so that the tree The tree is not easily blown down by the wind, which is beneficial for supporting the tree and can meet the needs of supporting trees with different trunk diameters. In addition, since the first tension spring 22 and the first pressure spring 32 are elastic, they can provide space for the growth of the tree trunk diameter and meet the needs of tree growth. When the wind is too strong and the tree is shaken, the elastic force of the first tension spring 22 causes the first arc plate 23 to straighten the tree toward the middle, and the elastic force of the first pressure spring 32 straightens the tree toward the middle through the second arc plate 33, thereby preventing the tree from falling down and enhancing the stability of the tree. The force acts to buffer the first curved plate 23, and the elastic force of the first pressure spring 32 acts to buffer the second curved plate 33, preventing the tree from shaking and being hard squeezed by the first curved plate 23 and the second curved plate 33, thereby preventing the tree skin from being damaged and helping to protect the tree. When the tree shakes, the second curved plate 33 is squeezed to move inward and outward, and the first pressure spring 32 deforms adaptively, and the second curved plate 33 moves outward to squeeze the reinforcing plate 34 downward, so that the reinforcing plate 34 is inserted deeper into the ground, thereby helping to enhance the stability of the support leg 1 and enhance the effect of the support leg 1 in supporting the tree. Example 2

[0031] On the basis of Example 1, Figure 1 and Figure 6As shown, it also includes a pressing mechanism 4, which includes a swing rod 41, a torsion spring 42, a second fixed rod 43 and a second fixed plate 44. The second fixed rod 43 is welded to the middle part of the support leg 1, and the swing rod 41 is installed on the second fixed rod 43 through a bearing. The front and rear parts of the second fixed rod 43 are wound with a torsion spring 42, and the inner and outer ends of the torsion spring 42 are respectively fixed to the swing rod 41 and the second fixed rod 43. The upper part of the swing rod 41 on the right side contacts the right part of the first arc plate 23 on the upper side, and the upper part of the swing rod 41 on the left side contacts the left part of the first arc plate 23 on the lower side. The second fixed plates 44 are welded to the reinforcing plates 34, and the second fixed plates 44 are tilted outward and downward. The swing rods 41 on the left and right sides are respectively in contact with the second fixed plates 44 on the left and right sides.

[0032] The shaking of the tree squeezes the first arc plate 23 to move inward and outward, and the first tension spring 22 deforms adaptively. The inward and outward movement of the first arc plate 23 causes the rocker arm 41 to swing inward and outward, and the torsion spring 42 deforms adaptively. When the lower part of the rocker arm 41 swings inward, it squeezes the second fixed plate 44 to move downward, thereby causing the reinforcing plate 34 to move downward. In this way, the reinforcing plate 34 can be further inserted into the ground, thereby making the supporting leg 1 more stable, which is conducive to further enhancing the effect of supporting the tree.

[0033] like Figure 1 and Figure 7 As shown, it also includes a correcting mechanism 5, which includes a first pressure plate 51, a third fixed rod 52, a fixed frame 53 and a second tension spring 54. The fixed frame 53 is welded between the right sides of the upper first fixed rod 21, and the fixed frame 53 is also welded between the left sides of the lower first fixed rod 21. The first pressure plate 51 is slidably connected to the fixed frame 53, and the second tension spring 54 is wound around the side of the first pressure plate 51 away from each other. The inner and outer ends of the second tension spring 54 are respectively fixed to the fixed frame 53 and the first pressure plate 51, and the third fixed rod 52 is bolted to the first pressure plate 51. The lower part of the third fixed rod 52 is in contact with the adjacent swing rod 41.

[0034] When the upper part of the swing arm 41 swings outward, the swing arm 41 squeezes the third fixing rod 52 to move outward, thereby causing the first pressure plate 51 to move outward and the second tension spring 54 to be stretched. When the upper part of the swing arm 41 swings outward and disengages from the third fixing rod 52, the second tension spring 54 is reset to cause the first pressure plate 51 to move inward. The first pressure plate 51 moves inward to straighten the shaking tree, thereby preventing the tree from falling over.

[0035] like Figure 1 , Figure 8 and Fig. 9As shown, a spray mechanism 6 is also included, and the spray mechanism 6 includes a water tank 61, a hose 62, a pressing pump 63, a spray plate 64 and an extrusion plate 65. The second arc plate 33 is fixedly connected with the water tank 61, and the water tanks 61 on the left and right sides are respectively fixedly connected to the first fixing plates 35 on both sides. The front and rear sides of the bottom of the water tank 61 are fixedly connected with the hose 62, and the hose 62 is connected to the water tank 61. The front and rear parts of the reinforcing plate 34 are welded with the spray plate 64, and the bottom of the spray plate 64 is opened with a plurality of A water outlet is provided, and a pressure pump 63 is fixedly connected to the spray plate 64. The pressure pumps 63 are connected to the spray plate 64. Each hose 62 corresponds to a pressure pump 63. The hoses 62 are connected to the corresponding pressure pumps 63. Extrusion plates 65 are bolted on both the front and rear sides of the lower part of the second arc plate 33. Each extrusion plate 65 corresponds to a pressure pump 63. The extrusion plates 65 are located on the inner side of the pressing head on the corresponding pressure pump 63. The pressing head of the pressure pump 63 and the pump body are provided with a spring.

[0036] The second curved plate 33 moves outward, driving the squeezing plate 65 to move outward. The squeezing plate 65 moves outward to press the pressing head on the pressing pump 63. The spring on the pressing pump 63 is compressed. Then the pressing pump 63 sucks the water in the water tank 61 into the inside of the pressing pump 63 and pumps the water out to the spray plate 64. The water then flows out of the spray plate 64 into the soil at the root of the tree. By adding water to the soil, the loose soil can be made tighter, thereby preventing the tree from shaking and falling. The second curved plate 33 moves inward, driving the squeezing plate 65 to move inward. The squeezing plate 65 no longer squeezes the pressing head of the pressing pump 63. The spring on the pressing pump 63 resets the pressing head of the pressing pump 63.

[0037] like Figure 1 and Fig.10 As shown, it also includes a compacting mechanism 7, which includes a connecting frame 71, a second pressure spring 72 and a second pressure plate 73. There are two connecting frames 71, and the two connecting frames 71 are respectively slidably connected to the two second fixed rods 43. The second pressure springs 72 are wound around the front and rear sides of the upper part of the connecting frame 71, and the upper and lower ends of the second pressure spring 72 are respectively fixed to the connecting frame 71 and the second fixed rod 43. The lower part of the connecting frame 71 is welded with a second pressure plate 73, and the left and right swing arms 41 are respectively in contact with the inner sides of the left and right connecting frames 71, and the second pressure plates 73 are flush with the bottom of the supporting leg 1 to facilitate the second pressure plates 73 to be pressed on the soil. The reinforcing plate 34 is located on the inner side of the second pressure plate 73, and the spray plates 64 are located above the adjacent second pressure plates 73.

[0038] When the upper part of the swing rod 41 swings inward and outward, the swing rod 41 squeezes the connecting frame 71 to move up and down, and the second pressure spring 72 deforms adaptively. The connecting frame 71 moves up and down to drive the second pressure plate 73 to move up and down. The second pressure plate 73 moves up and down to beat the soil, which can make the soil at the root of the tree more compact, making the tree less likely to shake, which helps to prevent the tree from falling over.
