[0002] Gardening and greening is an important part of urban construction. It can actively shape the regional image and promote regional sustainable development. In today's water shortage, on the premise of ensuring the high-quality development of gardening and greening, orderly promoting the application of various water-saving measures in gardening and greening, scientifically utilizing water resources, and striving to build water-saving gardens have become the industry's goals. The proportion of drip irrigation technology in the field of gardening and greening has gradually increased, especially in the northern region.

[0003] At present, the commonly used drip irrigation devices for landscaping are mainly drip irrigation bags hung on trees, ground drip irrigation pipes, etc., which can allow water to slowly penetrate into the deep soil and the roots of trees, solving the problems of some shallow and smaller tree holes that are not easy to store water and seep water, and soil compaction. However, the existing drip irrigation devices also have limitations. The slow penetration of water droplets will cause the roots of plants to often float on the surface, and the roots will develop too much horizontally and cannot go deep, which is not conducive to the growth of large trees. Furthermore, under hot weather conditions, the drip irrigation water floating on the soil surface evaporates quickly, and the evaporation rate accounts for a high proportion, which is not conducive to improving water use efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide an underground drip irrigation device and a system thereof, aiming to solve the problem that the drip irrigation of the existing drip irrigation system floats on the surface.

[0008] Preferably, a gravel cushion layer is provided below the soft permeable pipe.

[0009] Preferably, the buried drip irrigation device further comprises a ceramsite ring layer wrapped around the outside of the soft permeable pipe ring.

[0024] The utility model further provides a buried drip irrigation device.

[0025] Reference Figures 1 to 3 In this preferred embodiment, a buried drip irrigation device includes a main water supply pipeline 1, a water supply pipeline connector 2, a patch-type drip irrigation belt ring 3 and a soft permeable pipe ring 4, wherein:

[0026] The main water supply pipeline 1 and the soft permeable pipe ring 4 are both located underground, the patch-type drip irrigation belt ring 3 is located inside the soft permeable pipe, the water supply pipeline connector 2 connects the patch-type drip irrigation belt ring 3 and the main water supply pipeline 1, and the soft permeable pipe ring 4 is arranged around the outside of the seedling soil ball 7.

[0027] Specifically, in this embodiment, the main water supply pipeline 1 and the water supply pipeline connector 2 are both made of PC. The patch-type drip irrigation belt ring 3 is made of PE.

[0028] Furthermore, the buried drip irrigation device further comprises a gravel cushion layer 5 located below the main water supply pipe 1 , and the gravel cushion layer 5 supports the main water supply pipe 1 .

[0029] Furthermore, a gravel cushion layer 5 is provided below the soft permeable pipe. The gravel cushion layer 5 acts as a stabilizing device, thereby helping the irrigation water to drip and penetrate downward, and inducing the plant roots to penetrate deeply downward.

[0030] Further, refer to Figure 1 The buried drip irrigation device also includes a ceramsite ring layer 6 wrapped around the outside of the soft permeable pipe ring 4. The soft permeable pipe ring 4 is provided with ceramsite ring layers 6 on the top, bottom, left and right sides, so as to wrap it in all directions. The function of the ceramsite ring layer 6 is to increase the air permeability of the device and promote the penetration of other forms of irrigation water such as rainwater, spray irrigation water, etc. into the roots of plants.

[0031] In addition, refer to Figure 1 and Figure 2 , the bark covering 8 is spread on the surface layer of the tree hole to reduce water evaporation. In this embodiment, the thickness of the ceramsite ring layer 6 is greater than the thickness of the gravel cushion layer 5. The gravel cushion layer 5 and the gravel cushion layer 5 below the soft permeable pipe are both in annular shape.

[0032] The soft permeable pipe ring 4 is located in the middle and lower layers of the seedling soil ball 7. The buried drip irrigation device is buried below the frozen soil layer. The patch-type drip irrigation belt ring 3 is arranged around the inside of the soft permeable pipe ring 4. The patch-type drip irrigation belt ring 3 and the main water supply pipeline 1 are interconnected through the water supply pipeline connector 2, so that the pressurized water is evenly transported to the drippers around the seedling soil ball 7. The patch-type drip irrigation belt ring 3 is placed in the soft permeable pipe ring 4, and the drip irrigation belt body is not in direct contact with the soil, which can prevent the dripper from being blocked and slow down the aging and deformation of the drip irrigation belt. The soft permeable pipe can also help water permeation and filtration.

[0033] Specifically, the main water supply pipeline 1 is connected to a plurality of patch-type drip irrigation tape rings 3 inside the soft permeable pipe rings 4 .

[0034] The buried drip irrigation device proposed in this embodiment improves the seedling drip irrigation system to the middle and lower layers of the tree pit, and uses a soft permeable pipe to protect the drip irrigation belt, so that the drip irrigation system can play a role in the deep soil layer. The burial depth is adjusted according to the tree species. While playing the role of slow water penetration, it induces the plant roots to go deep downward, improves wind resistance, and also improves water use efficiency (solving the problem of excessive evaporation in the prior art). At the same time, the local buried drip irrigation device avoids messy pipes and hanging bags in appearance, and is more beautiful.

[0035] The utility model further provides a buried drip irrigation system.

[0036] In the preferred embodiment, a buried drip irrigation system includes a plurality of buried drip irrigation devices connected in series. The specific structure and beneficial effects of the buried drip irrigation devices refer to the above embodiments and will not be described in detail here.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
