Among them, a subsoiler is a device specifically used to improve the quality of saline-alkali land. It increases soil air permeability and water permeability by subsoiling and plowing the land, thereby reducing soil salinity and increasing soil fertility. At the same time, mechanical vibration can also break hard soil, making it easier to cultivate and plant. Another common soil improvement device is a tiller, which can thoroughly plow, break, and pulverize the land, eliminate soil crust and waterlogging, thereby increasing land fluidity and fertility, restoring land structure and biodiversity, and improving land disaster resistance and drought tolerance.

[0004] At present, there is a significant problem with traditional soil improvement devices for saline-alkali land and sandy wasteland: they need to transport solid waste to an artificial soil preparation workshop for processing, convert it into artificial soil, and then transport it to the land to be repaired. This process of two loading and unloading and transshipment is not only cumbersome but also results in too high a cost for solid waste transportation, usually accounting for more than 90% of the repair cost. Such a high cost seriously restricts the wide promotion and application of artificial soil in soil repair. In addition, it is also very difficult to achieve uniform coverage during the laying process of solid waste-based artificial soil, which further affects the effect and efficiency of soil repair. Therefore, seeking more economical and efficient soil improvement technologies and devices has become an urgent problem to be solved.

Below the retaining plate 205, there is a wedge plate 206, and the wedge plate 206 is used to export the improved soil to the outside, realizing the automatic control of the soil improvement process. The switch of the retaining plate 205 is connected to the external time sensor, improving the accuracy and efficiency of the operation; the wedge plate 206 facilitates the export of the improved soil.

[0046] Embodiment 2:

[0047] As Figure 4 shown, on one side of the stirring mechanism 2, there is a medicine storage mechanism 3. The medicine storage mechanism 3 includes a medicine storage tank 301. Inside the medicine storage tank 301, there is a liquid pump, and the output end of the liquid pump is provided with a medicine delivery pipe 302. The side of the medicine delivery pipe 302 far from the medicine storage tank 301 penetrates through the stirring tank 201 and is installed with a high-pressure nozzle 207, and the high-pressure nozzle 207 is detachably connected to the inner wall of the medicine storage tank 301. On the back of the medicine storage tank 301, there is a medicine inlet 304, and at the bottom of the medicine storage tank 301, there is a discharge port 303. The discharge port 303 is used to discharge the waste liquid of the medicine. The liquid pump in the medicine storage tank 301 accurately adds the soil conditioner or fertilizer to the soil through the medicine delivery pipe 302 and the high-pressure nozzle 207, improving the effect and quality of soil improvement; at the same time, the settings of the medicine inlet 304 and the discharge port 303 facilitate the addition of the medicine and the discharge of the waste liquid.

[0048] As Figure 1 shown, at the front end of the bucket 105, there is a soil loosening mechanism 4. The soil loosening mechanism 4 includes a second motor 401.

Before excavation, the soil loosening mechanism 4 loosens the soil through the soil loosening roller 402, reducing the soil hardness and improving the excavation efficiency and effect; at the same time, it also helps the subsequent uniform mixing of the soil conditioner. The setting of the seat 103 provides a control center for the operator, further improving the comfort and efficiency of the operation.

[0049] During implementation, an appropriate amount of soil conditioner or fertilizer needs to be added to the medicine storage tank 301 through the medicine inlet 304. Then, the operator sits on the seat 103 and is ready to start the device. Subsequently, start the crawler wheels 102 at the bottom of the vehicle body 101 to drive the device to move to the saline-alkali land or sandy wasteland that needs to be improved. According to the terrain and operation requirements, adjust the position and direction of the vehicle body 101. At this time, start the second motor 401 of the soil loosening mechanism 4 to drive the soil loosening roller 402 to rotate and lower the bucket 105, so that the soil loosening roller 402 contacts the ground and starts the soil loosening operation to reduce the soil hardness;

[0050] Start the motor of the import arm 104, drive the bucket 105 to descend and insert it into the soil. The spiral blade roller 106 inside the bucket 105 starts to rotate, guiding the soil towards the soil inlet 107. The conveyor belt 109 starts to operate under the drive of the conveyor motor, transporting the soil from the through slot 108 to the mixing tank 201 of the mixing mechanism 2;

[0051] Subsequently, the soil enters the sleeve cage 204 through the inlet 202. The first motor 208 on the back of the mixing tank 201 starts, driving the mixing roller 209 to rotate in the mixing chamber 203 to mix the soil. At the same time, the liquid pump of the medicine storage mechanism 3 starts to work, spraying the conditioner or fertilizer into the mixing chamber 203 through the medicine delivery pipe 302 and the high-pressure nozzle 207 to mix with the soil;

[0052] After the mixing is completed, the retaining plate 205 separates under the drive of the motor, and the improved soil drops onto the wedge plate 206. The wedge plate 206 guides the improved soil to the outside for subsequent collection or treatment. If necessary, the waste liquid of the medicine in the medicine storage tank 301 can be discharged through the discharge port 303.
