[0026] In this embodiment, a traction frame 37 is fixedly installed on the front wall of the main body 1 to facilitate the connection of tractors and other tractor vehicles.

[0027] Its detailed connection methods are well-known technologies in this field; such as Figure 1 As shown, load the repair materials: Add the alkaline repair agent (such as lime, biochar, etc.) and the required liquid (water or other solution) to the corresponding compartments of the storage tank 2, ensuring that the materials do not clump. Check the condition of the components: Confirm that key components such as the electric track wheel 6, the tilling blade, and the spray head 21 are undamaged, and that the hydraulic system, motor, and sensors are in normal working condition.

[0028] The lifting control motor 8 is activated via the control panel, driving the lead screw 10 to rotate and raising / lowering the threaded sleeve 11, thus adjusting the height of the equipment chassis to adapt to muddy or rugged terrain.

Driven by a mixing motor 18, the auger blades 20 in the mixing tank 16 thoroughly mix the remediation agent with water to form a suspension. The spray head 21 performs wide-area or targeted spraying according to instructions, ensuring uniform coverage of the acidified area with the remediation agent. The turning motor 26 is started, driving the drive sprocket 27, which in turn rotates the driven sprocket 29 and the turning roller 28 via a transmission chain 30. The L-shaped turning blade 25 cuts into the soil for deep loosening. The height of the turning frame 24 is adjusted by raising the hydraulic cylinder 31 to control the turning depth (e.g., shallow remediation or deep improvement). During the turning process, the remediation agent mixes naturally with the soil, improving neutralization efficiency.

[0030] After the operation is completed, connect the tractor or other towing vehicle via the towing frame 37 and switch to the support wheel 32 mode to quickly transfer the equipment.

[0031] Empty the remaining material from storage tank 2 and mixing tank 16, and rinse spray head 21 to prevent clogging.
