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.

[0030] Specific embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.11 As shown, a tree grate includes a plate body 1, each plate body 1 is provided with an arc-shaped groove 2, all the plate bodies 1 are spliced ​​to form a square frame structure, all the arc-shaped grooves 2 are spliced ​​to form tree holes 3, the splicing surface between the splicing ends of two adjacent plate bodies 1 is divided into an upper splicing surface 4 and a lower splicing surface 5, the upper splicing surface 4 and the lower splicing surface 5 are cross-arranged, a connecting ring 6 is arranged at the bottom of each splicing end of the plate body 1, bolts and nuts are additionally provided, the connecting rings 6 of two adjacent plate bodies are sleeved on the same bolt and clamped between the nut and the nut of the bolt, and the through hole on the connecting ring 6 for passing the bolt is an oblong hole.

[0031] As a further improvement of the present invention, an upper arc groove 7 is provided on the upper end surface of the plate body 1, and a lower arc groove 8 is provided on the lower end surface of the plate body 1. All upper arc grooves 7 on the same plate body 1 are arranged radially, and all lower arc grooves 8 on the same plate body 1 are also arranged radially, and the bending direction of the lower arc groove 8 is opposite to that of the upper arc groove 7. The sum of the depth of the upper arc groove 7 and the depth of the lower arc groove 8 is equal to the thickness of the plate body 1. Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the pattern design of the upper arc groove 7 and the lower arc groove 8 is elegant and beautiful, easy to clean, and the pattern is radial. The spacing between two adjacent upper arc grooves 7 and the spacing between two adjacent lower arc grooves 8 are gradually increased from one end close to the arc groove 2 to the other end. All upper arc grooves 7 and all lower arc grooves 8 are evenly distributed with the tree hole 3 as the center. The upper arc grooves 7 and the lower arc grooves 8 are staggered in positive and negative directions to prevent large debris from falling into the tree pit and prevent pedestrians from spraining their ankles due to large gaps.

[0032] As a further improvement of the present invention, the arc-shaped groove 2 is a stepped groove, and the bottom of the inner wall of the plate body 1 bulges inward to form a step structure 9. Figure 5 , Figure 6 and Figure 8 As shown, the edge of the arc-shaped groove 2 of the plate body 1 is provided with a step structure 9 with a width of 1.5 cm. Inner circles of different widths can be placed at the step structure 9 according to the thickness of the tree. The pattern of the inner circle corresponds to the pattern of the outer circle, and the widths are different. It can be made according to the tree's diameter at breast height, so as to adjust the distance between the grate and the tree to make it fit better and at a moderate distance. The step structure 9 enables the inner circle to play a load-bearing role when placed on the plate body 1 and fit up and down, so that the upper end surface of the plate body 1 and the inner circle are in the same plane without unevenness, and the plate body 1 and the inner circle are an integral whole.

[0033] As a further improvement of the present invention, the thickness of the plate body 1 is 2.5-3.5 cm and preferably 3 cm, and the height of the step structure 9 is less than or equal to half of the thickness of the plate body 1, so that the step structure 9 has a sufficient thickness to support the inner ring placed thereon.

[0034] As a further improvement of the present invention, a weight-reducing groove 10 is provided on the lower end surface of the plate body 1, and the weight-reducing groove 10 is located between two adjacent lower arc-shaped grooves 8.

[0035] As a further improvement of the present invention, the depth of the weight-reducing groove 10 is equal to half the thickness of the plate body 1. This can ensure that the plate body 1 has sufficiently high strength and bearing capacity, and the weight-reducing groove 10 is deep enough to reduce the overall weight of the tree grate as much as possible.

[0036] As a further improvement of the present invention, half of the upper arc groove 7 and half of the lower arc groove 8 are simultaneously provided at the two joint ends of the plate body 1. The half upper arc grooves 7 of two adjacent plate bodies 1 are spliced ​​to form a whole upper arc groove 7, and the half lower arc grooves 8 of two adjacent plate bodies 1 are spliced ​​to form a whole lower arc groove 8. Each plate body 1 is simultaneously provided with nine whole upper arc grooves 7 and nine whole lower arc grooves 8. Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, after the board bodies 1 are spliced, each board body 1 has ten patterns, which are beautiful and uniform, and the gaps are centered.

[0037] As a further improvement of the present invention, a light strip is provided on the upper end surface of the plate body 1. After absorbing sunlight during the day, the light strip can effectively and continuously emit light at night, achieving the effect of lighting and decoration, and being more beautiful.

[0038] As a further improvement of the present invention, a positioning block protruding downward is provided on the lower end surface of the plate body 1. During installation, the positioning block is inserted below the ground to play a limiting role and prevent the plate body 1 from deflecting.

[0039] When the present invention is used in practice, the tree grate is made of ductile cast iron, which has high strength. After the mold is cast, the molten iron is cast according to the shape of the mold. The finished casting product is a single-piece plate body 1, each plate body 1 is provided with an arc-shaped groove 2, and four plate bodies 1 are spliced ​​together, and two connecting rings 6 can be connected together by a bolt and a nut, so that the two plate bodies 1 are connected together to form an integral square frame structure. The arc-shaped grooves 2 on the four plate bodies 1 are spliced ​​to form a tree hole 3, and the tree hole 3 can be located at the center of the square frame structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it can also be biased to one side, such as Fig.12 and Fig.13As shown. After all the plates 1 are spliced, there are forty upper arc grooves 7 and forty lower arc grooves 8. The splicing surface between the splicing ends of two adjacent plates 1 is divided into an upper splicing surface and a lower splicing surface. The upper splicing surface and the lower splicing surface are cross-set. This cross-stitching splicing is more stable and has a greater load-bearing capacity. The distance between the four sides can also be adjusted by telescopic adjustment, thereby changing the size of the tree hole 3 to meet the use requirements of trees of different thicknesses. The thickness of the plate 1 is 3cm, the depth of the upper arc groove 7 and the lower arc groove 8 are both 1.5cm, and the width of the part of the plate 1 between the lower arc groove 8 and the weight-reducing groove 10 is 0.15cm. As a reinforcing rib, the thickness of the plate 1 is not reduced and the load-bearing capacity is large and the strength is high. It can withstand a weight of 5 tons. Stamping and slotting saves materials and avoids waste, reduces weight, and saves time and effort in installation and transportation. The overall size of the tree grate can be changed to enlarge or reduce, and can be made according to tree pits of different sizes. The size of the tree hole 3 can be enlarged according to the size of the tree's diameter at breast height.
