[0002] Drip irrigation is a method of local irrigation by using plastic pipes to deliver water to the roots of crops through the orifices or drippers on a capillary tube with a diameter of about 10 mm. Drip irrigation is a method of agricultural irrigation that can effectively improve the utilization rate of water resources. Drip irrigation is an irrigation method that drips water and the moisture and nutrients required by crops into the soil in the root zone of crops evenly and slowly in the form of water drops through a pipeline system and an emitter installed on a capillary tube according to the water requirements of crops. Drip irrigation does not destroy the soil structure, and the water, fertilizer, air, and heat inside the soil are often kept in a good condition suitable for crop growth. The evaporation loss is small, no surface runoff is generated, and there is almost no deep leakage. Therefore, it is a water-saving irrigation method. In the prior art, in order to achieve drip irrigation, it is necessary to lay a drip irrigation network pipe, which has a complex structure, occupies a large area, and is not conducive to later maintenance. In addition, the existing drip irrigation pipe is generally laid on one side of the plant root system, which cannot achieve accurate water supply to the plant and has low water supply efficiency.

The negative pressure is used for the next stage of soil moisture infiltration, and finally the irrigation process is completed. The irrigation operation can be completed without providing additional pressure conditions. It is simple, easy to use and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of drip irrigation pipes arranged side by side are positioned by a bracket, and each drip irrigation pipe is arranged on one side of the plant. The drip irrigation area of ​​the soil is small, the drip irrigation efficiency is low, and external pressure is required to achieve pressure infiltration, which consumes a lot of energy.

[0041] In view of this, the designer provides a portable underground irrigation device with a simple structure, convenient and flexible use, which can achieve precise drip irrigation of plants and reduce energy and costs.

[0042] Please combine Figure 1-Figure 4In this embodiment, the portable underground irrigation device includes a water tank 100, a transfer tube 200, a water distributor 300 and a plurality of drip tube bodies 400; the water tank 100 is connected to the water distributor 300 through the transfer tube 200; the water distributor 300 is provided with a plurality of water outlets 311, and the plurality of drip tube bodies 400 are respectively connected to the plurality of water outlets 311 in a one-to-one correspondence, and the plurality of drip tube bodies 400 are all used to be plugged into the soil to support the water tank 100 and the water distributor 300, and the plurality of drip tube bodies 400 form an escape space for accommodating plants.

In addition, the cooperation of multiple dropper bodies 400 can better stabilize the water distributor 300 and the water storage tank 100, and it is not easy to tip over during operation, and it is safe and reliable to use.

[0048] For example, in this embodiment, the number of the dropper bodies 400 is three, and the three dropper bodies 400 are distributed on the same circumference.

[0049] In this embodiment, optionally, each dropper body 400 is detachably connected to the water distributor 300. The dropper body 400 is easy to assemble and disassemble, and can be disassembled after a failure, which is conducive to maintenance and replacement, thereby reducing maintenance costs.

[0050] It should be understood that the dropper body 400 and the water distributor 300 can be detachably matched by screw connection.

In actual application, the corresponding connecting column 330 can be selectively closed with the screw plug, and there is no need to use the dropper body 400 for drip irrigation, which saves costs. At the same time, when one or several dropper bodies 400 need to be replaced but cannot be replaced in time, that is, part of the dropper body 400 is damaged and the rest of the dropper body 400 can be used normally, the damaged dropper body 400 can be disassembled first and the corresponding connecting column 330 can be closed with the screw plug, and the normal dropper body 400 can continue to be used, reducing the vacuum period.

[0055] In this embodiment, optionally, the transfer tube 200 is detachably connected to the housing 310. The transfer tube 200 and the housing 310 can be separated to reduce maintenance costs.
