The bottom of the connecting plate 21 is fixedly connected with a water collection tank 22. The upper surface and the upper parts of both sides of the water collection tank 22 are provided with a plurality of water permeable holes 23. By driving the stirring shaft 12 to rotate through the stirring motor 13, the stirring rods 14 are driven to rotate, so as to facilitate the full stirring of the soil conditioner and water in the improvement box 11.

[0026] In this embodiment, specifically: the bottom of the rear surface of the water collection tank 22 is communicated with a drain pipe 24. The water outlet end of the drain pipe 24 is communicated with a drainage pump 25. The water outlet end of the drainage pump 25 is communicated with a drainage main pipe 26. By starting the drainage pump 25, the water in the water collection tank 22 is discharged through the drain pipe 24 and the drainage main pipe 26.

[0027] In this embodiment, specifically: a liquid level sensor 27 is arranged at the front part of one side of the inner side wall of the improvement box 11. The liquid level of the soil conditioner inside the improvement box 11 can be monitored in real time through the liquid level sensor 27.

[0028] In this embodiment, specifically: a controller 28 is fixedly connected to the upper part of the rear surface of the improvement box 11. The output end of the liquid level sensor 27 is electrically connected to the input end of the controller 28. The input ends of the stirring motor 13, the water pump 15 and the drainage pump 25 are all electrically connected to the output end of the controller 28. Through the intelligent control of the controller 28, the whole process of automatic operation can be realized.

[0029] In this embodiment, specifically: a feed inlet 29 is opened at the rear part of the upper surface of the improvement box 11. A feed hopper 30 is fixedly connected to the inner side wall of the feed inlet 29. The soil conditioner can be conveniently added into the improvement box 11 through the feed hopper 30 arranged in the feed inlet 29.

[0030] In this embodiment, specifically: a water inlet pipe 31 is connected to one side of the upper surface of the improvement box 11. An electromagnetic valve 32 is installed on the outer side wall of the water inlet pipe 31 near the improvement box 11. The input end of the electromagnetic valve 32 is electrically connected to the output end of the controller 28. The opening and closing of the water inlet pipe 31 can be conveniently controlled through the electromagnetic valve 32.

[0031] In this embodiment, specifically: a limiting ring 33 is fixedly connected to the center of the inner bottom wall of the improvement box 11. The bottom of the outer side wall of the stirring shaft 12 is rotatably connected to the inner side wall of the limiting ring 33. By rotating the bottom of the outer side wall of the stirring shaft 12 inside the limiting ring 33, the stirring shaft 12 is limited, thereby increasing the stability of the rotation of the stirring shaft 12.

[0032] In this embodiment, specifically: a display screen 34 is arranged on the upper part of the rear surface of the controller 28, and a control panel 35 is arranged on the lower part of the rear surface of the controller 28 near the display screen 34. The corresponding improvement parameters, such as stirring time, drainage time, water inflow, etc., can be conveniently set through the display screen 34 and the control panel 35 on the controller 28.

[0033] During the working principle or structural principle, when in use, the corresponding improvement parameters, such as stirring time, drainage time, water inflow, etc., are set through the control panel 35 of the controller 28. The required soil conditioner, such as gypsum, organic matter, etc., is added into the improvement box 11 through the feed hopper 30 on the feed inlet 29. The electromagnetic valve 32 is started through the controller 28, so that the water source enters the improvement box 11 through the water inlet pipe 31. After the liquid level sensor 27 monitors that the water level in the improvement box 11 reaches the preset water level, the information is fed back to the controller 28. The controller 28 automatically closes the electromagnetic valve 32 and starts the stirring motor 13. The stirring motor 13 drives the stirring shaft 12 and the stirring rod 14 to rotate, and fully stirs the soil conditioner and water in the improvement box 11 to make them evenly mixed. When the stirring reaches the preset time, the controller 28 turns off the stirring motor 13. At the same time, the controller 28 starts the water pump 15, and pumps the improved liquid in the improvement box 11 into the main improvement pipe 17 through the connecting pipe 16, and then through the connecting branch pipe 18 and the improvement branch pipe 19, and finally sprays it onto the surface of the saline-alkali land by the spray head 20. During the spraying process of the improved liquid, part of the water will seep into the soil, and at the same time, the excess water on the saline-alkali land will flow into the water collecting tank 22 through the water permeable holes 23. When the water level in the water collecting tank 22 reaches a certain height, the controller 28 starts the drainage pump 25, and discharges the water in the water collecting tank 22 through the drain pipe 24 and the main drainage pipe 26 to keep the drainage of the water collecting tank 22 unobstructed.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
