The bottom groove 111 can be opened or not according to the soil conditions. The bottom groove 111 allows the saline-alkali water to flow directly to the alkali drainage pipe 1, and finally the saline-alkali water is discharged through the alkali drainage pipe 1.

[0043] A controller 5 is fixedly connected to one side of the processing box 4, a liquid level detector 51 is fixedly connected to the inner wall of the processing tank 42, a liquid outlet pipe A44 is fixedly connected to one side of the processing box 4, a liquid pump is provided at the connection between the liquid outlet pipe A44 and the processing box 4, the controller 5 is electrically connected to the liquid level detector 51, the liquid pump, the water pump and the three-way valve 29, and the control of the drainage device and the corresponding drainage operation of the liquid level change inside the processing tank 42 are realized through the setting of the controller 5, the liquid level detector 51 and the liquid outlet pipe A44.

[0044] The controller 5 is provided with a control module for human-computer interaction, one end of the control module is connected to a liquid level detection module for controlling the liquid level detector 51 to detect the liquid level height inside the treatment tank 42, one end of the liquid level detection module is connected to a drainage module for controlling the liquid pump and the liquid outlet pipe A44 to discharge the treatment liquid, one end of the control module is connected to a drive module for controlling the movement of the carriage 3, one end of the drive module is connected to a water supply module for controlling the water spraying head 35, and the other end of the control module is connected to a switch for controlling the three-way valve 29. The electromagnetic drive module for switching the state and drainage direction performs human-machine interaction through the controller 5, thereby controlling the movement of the carriage 3, the fresh water tank 41 supplying water to the sprinkler head 35, and the switch state of the three-way valve 29 and the drainage direction switching. When treating saline water, when the liquid level inside the treatment tank 42 is too high, the liquid level detector 51 is used to sense and control the liquid pump and the liquid outlet pipe A44 to discharge the treated water. When the liquid level is lower than the lowest height detected by the liquid level detector 51, the liquid pump is closed to drain water, ensuring that the three-way valve 29 can have enough water to replenish the guide tank 272.

[0045] Specifically, when treating saline-alkali land, the driving structure inside the carriage 3 is controlled by the controller 5 to drive the driving wheel 31 below the carriage 3 to move in the track groove 211 along the direction of the guide plate 21. During the movement of the carriage 3, the water pump inside the fresh water tank 41 passes the fresh water in the fresh water tank 41 through the water pipe 411, the liquid outlet box 33 and the arm plate 34, and finally sprays out from the sprinkler head 35. The flow of fresh water drives the saline-alkali components in the saline-alkali land to flow into the inside of the plug plate 12, and is filtered through non-woven fabrics and quartz sand, and finally collected into the alkali drainage pipe 1. The bottom tank 111 can be opened or not according to the soil conditions. The bottom tank 111 allows the saline-alkali water to flow directly to the alkali drainage pipe 1, and finally the saline-alkali water is discharged through the alkali drainage pipe 1, and is discharged into the treatment tank 42 through the three-way valve 29 using the pumping branch pipe 281 and the pumping pipe 28;

[0046] During the movement of the carriage 3, the connecting side plate 23 is driven to move by the connecting vertical rod 311, and the meshing effect of the secondary sprocket 25 and the main sprocket 24 drives the chain 26 to transmit, and then drives the main sprocket 24 to rotate, and the guide screw 61 rotates accordingly. The cleaning box 64 moves along the direction of the guide screw 61 under the limiting action of the guide rod 61. When the cleaning box 64 moves toward the tail plate 62, the magnetic plate 631 is driven to move synchronously toward the tail plate 62 under the magnetic attraction of the inner magnetic ring 641. At this time, treated water is stored in the liquid guide groove 272. The movement of the magnetic plate 631 generates negative pressure, and the water in the liquid guide groove 272 is pumped into the liquid storage plate 63 through the one-way pressure valve A633. At the same time, the magnetic plate 631 moves to squeeze the other end of the liquid storage plate 63. The gas is discharged into the air guide groove 271 through the exhaust pipe 621, and the gas is discharged into the mixing component 43 through the air guide groove 271 and the inner air guide pipe 273, thereby blowing the impeller 433 to drive the stirring rod 436 to rotate, and drive the stirring blade 435 below to rotate. When the stirring rod 436 rotates, under the action of the protrusion 4321 and the stirring rod 436, the stirring rod 436 is driven to move up and down while rotating, and the stirring blade 435 is driven to stir up and down. At the same time, with the continuous blowing, the air pressure is increased to open the one-way pressure valve B434, and the air is discharged through the aeration pipe 45, and the liquid on the surrounding is gathered to the middle, and at the same time, the aeration effect is achieved, and the treatment reagent is added in conjunction with the injection pipe 46 to achieve the purpose of treating saline water and enhancing the mixing effect;

[0047] During the resetting process of the carriage 3, when the saline-alkali water treatment is completed, the treated stratified water is discharged from the liquid replenishing pipe 291 into the liquid guide groove 272 through the three-way valve 29 to replenish the water source for subsequent water spraying. The movement of the carriage 3 drives the chain 26 to reverse, drives the guide screw 61 to reverse, and allows the cleaning box 64 to move toward the bottom box 2. The magnetic plate 631 cooperates with the sealing ring 632 to squeeze the water between the liquid storage plate 63 and the bottom box 2. The water is discharged into the liquid storage tank 642 through the connecting hose 65 and the one-way pressure valve C, and is sprayed out through the liquid outlet pipe B643, the annular liquid outlet plate 644 and the nozzle 645. During the movement of the cleaning box 64, the effect of spraying water on the surface of the alkali drainage pipe 1 is achieved, and the impurities crystallized and flushed on the filter hole surface of the alkali drainage pipe 1. The arc scraper 646 cooperates with the nozzle 645 to spray water to achieve the effect of blowing away and scraping off the impurities, and finally achieves the purpose of facilitating the discharge and treatment of the saline-alkali water, while preventing the alkali drainage pipe 1 from being blocked and recycling the treated water.
