The sealing plug 2-3-4 is slidably sealed with the inner wall of the water spray pipe 2-1, and a ground-breaking cone 2-3-5 is fixed on the sealing plug 2-3-4. The ground-breaking cone 2-3-5 rests on the end face of the water spray pipe 2-1.

[0022] The pumping unit 3 includes: an electric telescopic rod 3-1 and a piston 3-2. The fixed end of the electric telescopic rod 3-1 is fixedly connected to the inner side surface of the cylindrical cavity 2 1-3. The movable end of the electric telescopic rod 3-1 is fixed with a piston 3-2. The piston 3-2 is slidably sealed with the inner wall of the cylindrical cavity 2 1-3.

[0023] The water tank unit 4 includes: a water tank 4-1, a solar panel 4-2 and a battery 4-3. The lower end of the water tank 4-1 is fixedly connected to the drip irrigation bucket 1-1 through a water pipe. A one-way valve is provided at the connection between the water pipe and the drip irrigation bucket 1-1 and is connected to the cylindrical cavity 1-2. The solar panel 4-2 and the battery 4-3 are fixed to the upper end of the water tank 4-1. The solar panel 4-2 is electrically connected to the battery 4-3, and the battery 4-3 is electrically connected to the electric telescopic rod 3-1.

[0024] The working principle of this utility model is:

[0025] The water tank 4-1 is set near the soil that needs to be repaired, and the repair agent is poured into the water tank 4-1. The solar panel 4-2 can generate electricity through sunlight and store it through the battery 4-3. The battery 4-3 provides power for the device. When using this device, the drip irrigation unit 1 is pre-buried in the underground of the soil that needs to be repaired, and the electric telescopic rod 3-1 is energized and retracted, thereby driving the piston 3-2 to move. The movement of the piston 3-2 generates negative pressure in the cylindrical cavity 2 1-3, and then generates negative pressure in the cylindrical cavity 1-2. The connecting pipe 1-6 plays the role of ventilation and liquid flow. The negative pressure of the cylindrical cavity 1-2 drives the repair agent in the water tank 4-1 through the repair cavity. The agent tube is drawn into the cylindrical cavity 1-2. At this time, the electric telescopic rod 3-1 is retracted to the limit. Then, the electric telescopic rod 3-1 is powered on to control the extension of the electric telescopic rod 3-1, driving the piston 3-2 to move, pushing the repair agent in the cylindrical cavity 1-2 and the cylindrical cavity 2 1-3 into the water spray pipe 2-1. The sealing plug 2-3-4 is pushed to move by the pressure of the water, and then the fixed column 2-3-1 is driven to move and compress the spring 2-3-2. The movement of the sealing plug 2-3-4 drives the soil-breaking cone 2-3-5 to move more conveniently, pushing the surrounding soil to the circumferential side, reducing the resistance of the sealing plug 2-3-4 to move. The sealing plug 2-3-4 moves to create a gap with the water spray pipe 2-1. At this time, the arc plate 2-3-3 moves to the outside of the water spray pipe 2-1, and the repair agent is sprayed out through the water spray pipe 2-1, impacting the arc plate 2-3-3, and then moves along the arc plate 2-3-3 to the surrounding soil. The arc plate 2-3-3 can increase the area of ​​the repair agent spraying, avoid the repair agent from being too concentrated, and make the repair agent better penetrate into the soil. As the repair agent in the cylindrical cavity 1-2 is continuously sprayed, the pressure in the cylindrical cavity 1-2 gradually decreases, and the spring 2-3-2 drives the sealing plug 2-3-4 to gradually move downward and reset until the reset is completed, that is, one drip irrigation is completed. The one-way valve can prevent the repair agent from being pushed back into the water tank 4-1 when the piston 3-2 moves. The sealing plug 2-3-4 can prevent soil from entering the water spray pipe 2-1 and blocking the water spray pipe 2-1. The above steps can be repeated for the next drip irrigation. The device has a simple structure and can be taken out for transportation or repair of the next piece of soil that needs to be repaired after the repair is completed. The pre-buried fixed nail plate 1-5 supports the device and prevents the device from sinking in the soil; rotating the two screws 1-4 can drive the drip irrigation barrel 1-1 to move upward, and then the depth of the device buried in the soil can be adjusted. The depth of the soil repair can be adjusted according to the need, that is, after the deep soil is repaired, the drip irrigation barrel 1-1 can be moved upward to repair the shallow soil.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
