DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0026] See also Figure 1-8 As shown, a greening sponge tree pool includes a tree pool body 1, a plurality of splicing shells 2 are placed around the inner wall of the tree pool body 1, and a plurality of tree protection blocks 3 are installed inside the splicing shells 2, a coarse sand water filter layer 4 is arranged inside the tree pool body 1 and below the splicing shells 2, and soil mixed with organic fertilizer is arranged below the coarse sand water filter layer 4, installation pipes 5 are arranged on the left and right sides of the tree pool body 1, and a plurality of seepage nozzles 6 are fixed on the surface of the opposite side of the installation pipe 5, and a water pipe 7 is connected to the side of the installation pipe 5 away from the seepage nozzle 6, A water pipe 7 passes through the tree pit main body 1 and extends to the top of the tree pit main body 1, and the lower half of the water pipe 7 is a retractable hose. Sealing boxes 8 are fixed on the left and right sides of the top of the tree pit main body 1 and above the water pipe 7. A positioning structure 9 is movably connected to the surface of one side of the mounting tube 5. Rotating rods 10 are rotatably connected to the top of the front and rear sides of the tree pit main body 1. A turning plate 11 is fixed to the surface of the rotating rod 10. A cavity 12 is opened inside the tree pit main body 1 and on the left side of the rotating rod 10. A driving structure 13 is movably connected to the inside of the cavity 12.

[0027] The present invention provides a greening sponge-type tree pit. On the one hand, a water pipe 7 and a sealing box 8 fixed above the water pipe 7 ensure that the roots of the trees absorb nutrients and water in a balanced manner during their growth. The roots of the trees can be directly irrigated to ensure that the trees obtain sufficient and appropriate amounts of water. When the trees encounter diseases and insect pests, the pesticides can be directly applied to the roots of the trees to achieve precise pesticide application, improve the prevention and control effects, and ensure that the roots of the trees absorb nutrients and water in a balanced manner during their growth. On the other hand, a soil-turning plate 11 fixed on the surface of a rotating rod 10 can be used to turn over the soil in the tree pit, thereby increasing the air and moisture content in the soil, increasing the activity of microorganisms in the soil, and improving the soil's ability to retain fertilizer and water.

[0028] The material of the tree protection block 3 is polyurethane, and the material of the splicing shell 2 is fiberglass. A plurality of support blocks 14 are fixed to the bottom of the splicing shell 2, and the support blocks 14 are arranged at the four corners of the bottom of the splicing shell 2. The thickness of the tree protection block 3 is 32 mm, and the thickness of the coarse sand water filter layer 4 below is 30 mm. The tree protection block 3 absorbs and evenly releases natural precipitation and maintenance water, and at the same time can form a full closure on the surface of the tree pool, reduce garbage retention, and improve the urban environment. The setting of the support block 14 can form a certain gap between the splicing shell 2 and the coarse sand water filter layer 4, thereby increasing the air permeability of the soil.

[0029] The positioning structure 9 includes a slide 91, a slider 92 and a connecting rod 93. The slide 91 is provided at the front and rear of the left and right sides of the inner wall of the tree pit body 1. The slider 92 is slidably connected to the inside of the slide 91. The connecting rod 93 is hinged to the surface of one side of the slider 92, and the other end of the connecting rod 93 is hinged to the surface of the mounting tube 5. The connecting rod 93 is tilted as a whole. A positioning block 15 is fixed to the surface of one side of the slider 92, and the positioning block 15 is slidably connected to the inner wall of the slide 91. A positioning bolt 16 is penetrated on one side of the positioning block 15, and the positioning bolt 16 is slidably connected to the positioning block 15. A plurality of positioning holes 17 are provided on one side of the inner wall of the slide groove 91, and the positioning bolts 16 are threadedly connected to the inner wall of the positioning hole 17. When the sliders 92 on both sides are pulled, the sliders 92 will pull the connecting rod 93 to move, so that the connecting rod 93 drives the mounting tube 5 to move, and adjusts the position of the mounting tube 5. The position of the mounting tube 5 is adjusted according to the size of the roots of the planted trees. After the position of the mounting tube 5 is adjusted, the staff can pass the positioning bolts 16 through the positioning block 15 and insert them into the corresponding positioning holes 17 to complete the fixing operation of the position of the mounting tube 5.

[0030] A first filter screen 18 is embedded in the top of the sealing box 8, and a second filter screen 19 is fixed at the bottom of the sealing box 8. The aperture of the filter holes on the surface of the first filter screen 18 is larger than the aperture of the filter holes of the second filter screen 19. When rainwater from the outside falls on the top of the sealing box 8, the first filter screen 18 can perform a preliminary filter on the rainwater, and the rainwater can be further filtered through the second filter screen 19. The filtered rainwater will enter the water pipe 7 below and directly irrigate the roots of the trees through the seepage nozzle 6 on the surface of the installation pipe 5.

[0031] The driving structure 13 includes a first bevel gear 131, a connecting shaft 132, a rotating rod 133, a second bevel gear 134 and a knob 135. The first bevel gear 131 is rotatably connected to the lower part of the left side of the inner wall of the cavity 12. The connecting shaft 132 is fixed to the right side of the first bevel gear 131, and the right end of the connecting shaft 132 passes through the tree pool body 1 and is fixedly connected to the left end of the rotating rod 10. The rotating rod 133 is arranged above the inside of the cavity 12, and the top end of the rotating rod 133 passes through the top of the tree pool body 1. The second bevel gear 134 is fixed to the bottom end of the rotating rod 133, and the second bevel gear 134 is connected to the first bevel gear 131. The bevel gears 131 are meshed with each other, and the knob 135 is fixed to the top of the rotating rod 133. The shielding frames 20 are fixed to the front and rear sides of the left side of the top of the tree pit main body 1, and the shielding frame 20 is located above the knob 135. When the staff is maintaining the trees, the staff can rotate the knob 135 on the left side, so that the knob 135 drives the rotating rod 133 to rotate, and the second bevel gear 134 drives the first bevel gear 131 to rotate, so that the connecting shaft 132 drives the entire rotating rod 10 to rotate, so that the turning plate 11 can turn the soil to loosen the soil and increase the air permeability and water permeability of the soil.

[0032] There are several turning plates 11, and the turning plates 11 are arranged in a triangular shape as a whole. The turning plates 11 are distributed in a ring shape on the left and right sides of the surface of the rotating rod 10. When the rotating rod 10 rotates, the turning plates 11 will stir the surrounding soil, so that the roots of the planted trees can breathe and absorb water more easily. Turning the soil can also break the hardened layer in the soil, improve the physical structure of the soil, and provide a better soil environment for the growth of trees.

[0033] Working principle: When the staff is carrying out construction, according to the size of the tree pit body 1, a pit of corresponding size is dug at the construction location, and then the tree pit body 1 is placed inside the pit. The staff puts the planted trees into the tree pit body 1. At this time, the staff adjusts the positions of the installation pipes 5 on the left and right sides according to the size of the trees planted this time, so that the installation pipes 5 are located on both sides of the roots of the trees. The staff fills the inside of the tree pit body 1 with soil, and the soil needs to be mixed with organic fertilizers. Then, a coarse sand water filter layer 4 is laid on top of the soil. The coarse sand water filter layer 4 uses sand with a fineness modulus of 3.7-3.1 and an average particle size of 1mm-0.5mm, and the sand is washed and dried. Then the staff takes out the splicing shell 2, lays the splicing shell 2 around the tree and above the coarse sand water filter layer 4, so as to complete the greening. During the installation and operation of the sponge-type tree pool, the tree protection block 3 will absorb and evenly release the water during natural precipitation and maintenance, ensuring the balanced absorption of nutrients and water by the roots during the growth of the tree. When the staff is watering and maintaining the tree, when the water flows above the sealing box 8, the water will enter the interior of the water pipe 7, and the seepage nozzle 6 on the surface of the installation pipe 5 will discharge the water, thereby directly watering the roots of the tree. When the tree is infected with diseases and insect pests, the staff can directly pour the medicine above the sealing box 8, so that the medicine directly acts on the roots of the tree to improve the treatment effect. When maintaining the tree, the staff can also rotate the knobs 135 on both sides, so that the rotating rod 10 drives the soil-turning plate 11 to rotate, and the soil is turned over by the soil-turning plate 11 to loosen the soil, so that the root system can breathe and absorb water more easily.
