One end of the second inclined plate is connected to the support plate, and the other end is connected to the top of the water tank. In actual manufacturing, the position where the first inclined plate is connected to the support plate is located at the end of the support plate that is not connected to the top of the water tank, and the position where the first inclined plate is connected to the top of the water tank is located at one end of the top of the water tank.

[0018] In this embodiment, see Figure 4 The control components include a connecting pipe 15-1, a lifting device 15-2 fixed inside the connecting pipe, and a piston 15-3 fixed to the power output end of the lifting device. The top of the connecting pipe is detachably connected to the bottom of the outlet pipe, and the piston is located inside the outlet pipe. In this embodiment, the lifting device can be an electric hydraulic cylinder, an electric pneumatic cylinder, or an electric telescopic rod. Preferably, a sealing plate 15-11 is provided at the bottom end of the connecting pipe to facilitate fixing the lifting device, and the lifting device is fixed to the sealing plate. In actual manufacturing, a partition plate 15-12 can also be provided inside the connecting pipe. The power output end of the lifting device passes through the partition plate and connects to the piston. The power output end of the lifting device and the partition plate can be slidably connected. During manufacturing, a hole is provided on the partition plate for the power output end of the lifting device to pass through; the inner diameter of this hole is slightly larger than the outer diameter of the power output end of the lifting device.

[0019] In a preferred embodiment, a third valve 20 is installed on the guide pipe near the support pipe, and the bypass pipe is connected to the guide pipe between the first valve and the third valve; a filter structure 21 is provided at the bottom end of the support pipe, wherein the filter structure can be a filter screen, a filter plate or a filter element, and its installation is well known to those skilled in the art, and will not be described in detail here.

[0020] In a preferred embodiment, there are multiple guide pipes, and the ends of the multiple guide pipes away from the water tank are connected by a common pipe 22; both the guide pipes and the support pipe are connected to the common pipe.

[0021] In the application of the aforementioned soil irrigation device, the bottom of the water tank is buried in the soil 23 below ground level to increase its stability. The flow guiding structure is designed in a triangular shape, allowing rainwater flowing downhill during the rainy season to flow to both sides of the water tank via the first and second inclined plates, preventing rainwater from flowing up the slope from impacting the water tank for a long time and causing damage. When irrigating the soil, when the water tank is full, the first and third valves can be opened, allowing water in the tank to flow into the guide pipe by potential energy. When the water level in the tank is lower than the top of the guide pipe, the first valve is closed and the second valve is opened to pump water from the tank. Water is transferred from the tank to the diversion pipe. After entering the diversion pipe, part of the water in the tank flows into the outlet pipe, and the other part flows into the support pipe. A lifting device lowers the piston, connecting the outlet hole to the outlet pipe, irrigating the soil above ground. The water entering the support pipe passes through a filter and permeates the soil. Each outlet pipe can have multiple or sets of outlet holes, such as three or more sets. The diameter of the uppermost outlet hole is smaller than that of the lowermost outlet hole. This allows control of the water flow by adjusting the piston's position. When the uppermost outlet hole is connected to the outlet pipe, the water flow is smaller. In drip irrigation mode, water seeps into the soil through the filter, suitable for maintaining a certain level of soil moisture, such as during the seedling stage. When both the top and bottom water outlets are open, the water output is larger, suitable for maintaining sufficient soil moisture, such as during the rapid water absorption and growth period of plant roots. When the soil moisture content is too high for a short period, the first and second valves can be closed, and the third valve opened. The piston is then pushed upwards by the lifting device, squeezing the gas in the guide pipe and support pipe, forcing it out through the support pipe into the soil and clearing the filter. While increasing the air content in the soil, the piston is pulled down to create negative pressure in the guide pipe and support pipe, which attracts water from the soil and temporarily stores it in the pipe. The water is then released after the soil moisture content is no longer too high. When the soil moisture content is too high for a short period of time, resulting in relatively low air content in the soil, the lifting device can be controlled to push the piston up and then pull it down past the outlet hole. After a certain interval, the water temporarily stored by the negative pressure is released, and the lifting device is controlled to push the piston up again. This process is repeated to provide air to the soil. This method is especially suitable for soils with relatively low density.

[0022] In actual production, rainwater collection inlets and water inlets can also be installed on the water tank. The first valve, second valve and third valve can be solenoid valves, and the lifting device can be an electric lifting device. These are all well known to those skilled in the art, and will not be elaborated here.

[0023] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
