The bottom of the moving column slide rail 45 is fixedly connected to the upper surface of the salt-washing and permeation box 1. The bottom of the biological agent box 47 is fixedly connected to the upper surface of the moving column slide rail 45. The switch 48 is arranged on one side of the biological agent box 47 close to the reciprocating lead screw 42. When the motor 41 starts to operate, the motor 41 drives the reciprocating lead screw 42 to rotate. The rotation of the reciprocating lead screw 42 drives the sliding block 43 to slide back and forth on the circumferential surface of the reciprocating lead screw 42. The sliding of the sliding block 43 drives the moving column 44 to slide on the inner wall of the moving column slide rail 45. The sliding of the moving column 44 can drive the nozzle 46 to slide. The water in the pumping water tank 3 is pumped out and flows into the nozzle 46 along the hose 7 to realize the cleaning of the soil layer to be permeated. Moreover, when the moving column 44 slides, it can toggle the switch 48. At this time, the biological agent in the biological agent box 47 will flow into the soil layer, increasing the improvement effect of the soil layer. The spraying device 4 further includes: a disc 49, a fixing column one 410, a connecting column one 411, a fixing plate 412, a positioning block 413, a rotating block 414, a fixing bracket one 415, a fixing column two 416, a permeation filter plate 417, a fixing bracket two 418, a rotating shaft one 419, and a rotating plate 420. The back surface of the disc 49 is fixedly connected to the front surface of the reciprocating lead screw 42. The fixing column one 410 is fixedly connected to the front surface of the disc 49. The front surface of the fixing plate 412 is fixedly connected to the inner wall of the salt-washing and permeation box 1. The upper surface of the positioning block 413 is fixedly connected to the lower surface of the fixing plate 412. The permeation filter plate 417 is installed on the lower surface of the salt-washing and permeation box 1. The bottom of the fixing bracket one 415 is fixedly connected to the upper surface of the permeation filter plate 417. The connecting column one 411 is rotatably connected to the front surface of the fixing bracket one 415. The bottom of the fixing bracket two 418 is fixedly connected to the upper surface of the permeation filter plate 417. One end of the rotating shaft one 419 is fixedly connected to the front surface of the fixing bracket two 418. The back surface of the rotating block 414 is fixedly connected to the other end of the rotating shaft one 419. The fixing column two 416 is fixedly connected to the front surface of the rotating block 414. The inner wall of the rotating plate 420 is fixedly connected to the circumferential surface of the rotating shaft one 419. The circumferential surface of the rotating shaft one 419 slides in the inner wall of the positioning block 413. The water outlet end of the hose 7 is arranged on the upper surface of the moving column 44. The moving column 44 slides in the moving column slide rail 45.The inner wall of the first connecting column 411 is in contact with the circumferential surface of the first fixed column 410, and the inner wall of the first connecting column 411 is in contact with the circumferential surface of the second fixed column 416. When the reciprocating lead screw 42 rotates, the reciprocating lead screw 42 drives the disc 49 to rotate, and the disc 49 drives the first fixed column 410 to rotate. Since the bottom end of the first connecting column 411 rotates on the first fixed bracket 415, the first fixed column 410 drives the first connecting column 411 to rotate left and right. The left and right rotation of the first connecting column 411 drives the second fixed column 416 to rotate left and right, and the second fixed column 416 drives the rotating block 414 to rotate left and right. Since the other end of the first rotating shaft 419 rotates on the second fixed bracket 418, and the fixing plate 412 and the positioning block 413 limit it, the left and right rotation of the rotating block 414 drives the first rotating shaft 419 to rotate left and right, and the first rotating shaft 419 drives the rotating plate 420 to rotate left and right. During the falling process of the soil blocks, the device can achieve a soil loosening effect, further improving the salt washing effect. The washed wastewater enters the wastewater collection tank 2 through the permeable filter plate 417.,

[0016] Working principle: When the motor 41 starts to operate, the motor 41 drives the reciprocating lead screw 42 to rotate. The rotation of the reciprocating lead screw 42 drives the sliding block 43 to slide back and forth on the circumferential surface of the reciprocating lead screw 42. The sliding of the sliding block 43 drives the moving column 44 to slide on the inner wall of the moving column slide rail 45. The sliding of the moving column 44 can drive the nozzle 46 to slide. The water in the pumping water tank 3 is pumped out and flows into the nozzle 46 along the hose 7 to realize the cleaning of the soil layer to be permeated. Moreover, when the moving column 44 slides, it can toggle the switch 48, and at this time, the biological agent in the biological agent tank 47 will flow into the soil layer, increasing the improvement effect of the soil layer. At the same time, when the reciprocating lead screw 42 rotates, the reciprocating lead screw 42 drives the disc 49 to rotate, and the disc 49 drives the first fixed column 410 to rotate. Since the bottom end of the first connecting column 411 rotates on the first fixed bracket 415, the first fixed column 410 drives the first connecting column 411 to rotate left and right. The left and right rotation of the first connecting column 411 drives the second fixed column 416 to rotate left and right, and the second fixed column 416 drives the rotating block 414 to rotate left and right. Since the other end of the first rotating shaft 419 rotates on the second fixed bracket 418, and the fixing plate 412 and the positioning block 413 limit it, the left and right rotation of the rotating block 414 drives the first rotating shaft 419 to rotate left and right, and the first rotating shaft 419 drives the rotating plate 420 to rotate left and right. During the falling process of the soil blocks, the device can achieve a soil loosening effect, further improving the salt washing effect. The washed wastewater enters the wastewater collection tank 2 through the permeable filter plate 417.

[0017] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the crushing device 5 includes: a supporting foot 51, a supporting plate 52, a pulley group 53, a second rotating shaft 54, a crushing cylinder 55, and a crushing box 56.

When large soil blocks enter the crushing box 56, the motor 41 rotates to drive the pulley group 53 to rotate, the pulley group 53 drives the second rotating shaft 54 to rotate, the second rotating shaft 54 drives the crushing cylinder 55 to rotate, and the crushing cylinder 55 crushes the large soil blocks in the crushing box 56. Since the crushing cylinder 55 rotates counterclockwise, a large number of crushed small soil blocks will accumulate on the right side of the crushing box 56. After crushing, they enter the supporting plate 52 through the small holes at the bottom of the crushing box 56. The crushing device 5 further includes: a second connecting column 57, a third fixed bracket 58, a third rotating shaft 59, a gear column 510, a rack box 511, and a soil pushing plate 512. The bottom of the third fixed bracket 58 is fixedly connected to the upper surface of the supporting plate 52, the third rotating shaft 59 rotates inside the third fixed bracket 58, the second connecting column 57 is rotatably connected to the circumferential surface of the third rotating shaft 59, the front surface of the gear column 510 is fixedly connected to the back surface of the third rotating shaft 59, the rack surface of the rack box 511 meshes with the gear column 510, the right side of the soil pushing plate 512 is fixedly connected to the left side of the rack box 511, the second rotating shaft 54 slides inside the inner wall of the crushing box 56, the inner wall of the second connecting column 57 contacts the circumferential surface of the first fixed column 410, the bottom of the rack box 511 slides on the upper surface of the supporting plate 52, and the lower surface of the soil pushing plate 512 contacts the upper surface of the supporting plate 52. When the first fixed column 410 rotates, the first fixed column 410 drives the second connecting column 57 to rotate. Since the third fixed bracket 58 limits the third rotating shaft 59, the second connecting column 57 drives the third rotating shaft 59 to rotate reciprocally, the third rotating shaft 59 drives the gear column 510 to rotate reciprocally, the gear column 510 drives the rack box 511 to move left and right reciprocally, and the rack box 511 pushes the soil pushing plate 512 to move left and right reciprocally, realizing the leveling of the small soil blocks at the lower layer of the crushing box 56. The small soil blocks then fall into the salt washing and infiltration box 1 through the holes on the supporting plate 52 for salt washing, effectively avoiding the problem that it is difficult for the soil to fall into the salt washing and infiltration box 1 due to the accumulation of soil blocks on the right side.

[0018] The filtering device 6 includes: an activated carbon filtering box 61, a connecting column slide rail 62, a third connecting column 63, a stirring plate 64, a water pipe 65, and a housing 66. The back of the activated carbon filtering box 61 is fixedly connected to the front of the wastewater collection box 2, and the back of the housing 66 is fixedly connected to the front of the salt washing permeation box 1.

When water enters the activated carbon filtering box 61 from the wastewater collection box 2, when the second fixed column 416 rotates, since the housing 66 is fixed to the salt washing permeation box 1 and the connecting column slide rail 62 is fixed to the housing 66, the second fixed column 416 drives the third connecting column 63 to slide in the inner wall of the connecting column slide rail 62, and the third connecting column 63 drives the stirring plate 64 to slide left and right. The filtered water re-enters the pumping water tank 3 through the water pipe 65, realizing the filtration of wastewater, the recycling of water resources, and the conservation of water resources. The filtering device 6 further includes: a movable column 67, an F-shaped column 68, a positioning plate 69, a third fixed column 610, an H-shaped column 611, a water pushing plate 612, and an elastic telescopic column 613. The bottom of the positioning plate 69 is fixedly connected to the bottom of the inner wall of the wastewater collection box 2, the F-shaped column 68 is rotatably connected to the inner wall of the positioning plate 69, the third fixed column 610 is rotatably connected to the inner wall of the F-shaped column 68, one end of the elastic telescopic column 613 is fixedly connected to the inner wall of the wastewater collection box 2, the front of the water pushing plate 612 is fixedly connected to the other end of the elastic telescopic column 613, the inner wall of the H-shaped column 611 is fixedly connected to the upper surface of the water pushing plate 612, the inner wall of the third connecting column 63 is in contact with the circumferential surface of the second fixed column 416, the bottom end of the movable column 67 is in contact with the inner wall of the F-shaped column 68, the circumferential surface of the movable column 67 slides in the inner wall of the permeation filter plate 417, and the bottom of the water pushing plate 612 is in contact with the bottom of the inner wall of the wastewater collection box 2. When the rotating plate 420 rotates downward, the rotating plate 420 presses the movable column 67 downward. Since the F-shaped column 68 is fixed to the inner wall of the wastewater collection box 2 by the positioning plate 69, the movable column 67 presses the F-shaped column 68 to rotate. The rotation of the F-shaped column 68 drives the third fixed column 610 to rotate, and the third fixed column 610 pushes the H-shaped column 611 to move forward. The H-shaped column 611 pushes the water pushing plate 612 to move forward. At this time, the elastic telescopic column 613 contracts to complete the water pushing, pushing the water away from the water outlet hole towards the water outlet hole, further accelerating the filtering speed.

[0019] Working principle: When large soil clods enter the crushing box 56, the motor 41 rotates to drive the pulley group 53 to rotate. The pulley group 53 drives the second rotating shaft 54 to rotate, and the second rotating shaft 54 drives the crushing cylinder 55 to rotate. The crushing cylinder 55 crushes the large soil clods in the crushing box 56. Since the crushing cylinder 55 rotates counterclockwise, a large number of crushed small soil clods will accumulate on the right side of the crushing box 56. After crushing, they enter the support plate 52 through the small holes at the bottom of the crushing box 56. When the first fixed column 410 rotates, the first fixed column 410 drives the second connecting column 57 to rotate. Since the third fixed bracket 58 limits the third rotating shaft 59, the second connecting column 57 drives the third rotating shaft 59 to reciprocate. The third rotating shaft 59 drives the gear column 510 to reciprocate, and the gear column 510 drives the rack box 511 to move left and right reciprocally. The rack box 511 pushes the earth-moving plate 512 to move left and right reciprocally, realizing the leveling of the small soil clods in the lower layer of the crushing box 56. The small soil clods then fall into the salt-washing permeation box 1 through the holes on the support plate 52, effectively avoiding the problem that it is difficult for the soil to fall into the salt-washing permeation box 1 due to the accumulation of soil clods on the right side.

[0020] When water enters the activated carbon filter box 61 from the wastewater collection box 2, when the second fixed column 416 rotates, since the outer shell 66 is fixed on the salt-washing permeation box 1 and the connecting column slide rail 62 is fixed on the outer shell 66, the second fixed column 416 drives the third connecting column 63 to slide on the inner wall of the connecting column slide rail 62. The third connecting column 63 drives the stirring plate 64 to slide left and right. The filtered water then re-enters the pumping water tank 3 through the water pipe 65, realizing the filtration of the wastewater, the recycling of water resources, and the conservation of water resources. When the rotating plate 420 rotates downward, the rotating plate 420 presses the movable column 67 downward. Since the F-shaped column 68 is fixed on the inner wall of the wastewater collection box 2 by the positioning plate 69, the movable column 67 presses the F-shaped column 68 to rotate. The F-shaped column 68 rotates to push the third fixed column 610 to rotate, and the third fixed column 610 pushes the H-shaped column 611 to move forward. The H-shaped column 611 pushes the water-pushing plate 612 to move forward. At this time, the elastic telescopic column 613 contracts to complete the water-pushing, pushing the water far from the water outlet hole towards the water outlet hole, further accelerating the filtration speed.
