The grinding assembly 4 is connected to the extraction assembly 3 through the feed port 102 arranged on the body 1. The grinding assembly 4 is driven by the first gear 32 in the extraction assembly 3. The liquid inlet assembly 5 includes a liquid tank 51, a liquid inlet pipe 52, a liquid outlet pipe 53 and a second cam 54 engaged with the first cam 22. The second cam 54 and the first cam 22 are rotatably accommodated in the cavity of the body 1. The liquid inlet pipe 52 connects the liquid tank 51 and the cavity inlet, and the liquid outlet pipe 53 connects the cavity outlet and the spray assembly 7. The spray assembly 7 is engaged with the special-shaped part 23 for transmission and is driven by the special-shaped part 23 for quantitative spraying. The liquid tank 51 is prepared with an organic liquid containing microbial fertilizer.

[0027] One end of the special-shaped part 23 is a sector tooth 23a, which meshes and drives with the quantitative filling disk 71 in the spray assembly 7, thereby intermittently driving the quantitative filling disk 71 to rotate for quantitative spraying of the liquid feed.

Cover plates are provided on the upper and lower sides of the planetary gear 45 to ensure that it always moves in the same horizontal plane and will not fall out. The height of the outer wall of the U-shaped lower grinding disc 42 is smaller than the outer wall of the U-shaped upper grinding disc 43 and the grinding assembly 4, and forms an annular feed chamber with the wall surface of the main body 1. The annular feed chamber is connected to the extraction assembly 3 through the feed port 102, so that the soil after extraction enters the grinding assembly 4.

[0030] Several protrusions are provided on the surfaces of the U-shaped lower grinding disc 42 and the U-shaped upper grinding disc 43 at relative positions, so that the compacted soil can be better ground. In addition, the U-shaped lower grinding disc 42 and the U-shaped upper grinding disc 43 are inclined toward the center, so that the soil can more easily enter the grinding surface from the periphery of the grinding assembly 4 and be discharged from the discharge channel 42a of the U-shaped lower grinding disc 42.

[0031] The spray assembly 7 includes a quantitative filling disk 71, a receiving disk 72 and a spray pipe 73; the quantitative filling disk 71 is meshed with the sector teeth 23a in the special-shaped part 23 for transmission, and a stepped arc channel 71b is provided in the quantitative filling disk 71, and a liquid inlet 71a connected to the liquid outlet pipe 53 is provided at one end of the arc channel 71b, and a liquid outlet 71c connected to the receiving disk 72 is provided at the other end.

Through the intermittent drive of the sector teeth 23a, the liquid inlet 71a set in the quantitative filling disk 71 is intermittently connected to the liquid outlet pipe 53, so that the intermittent liquid supply of the liquid inlet component 5 to the spray component 7 is completed; the liquid outlet 71c set in the quantitative filling disk 71 is always connected with the receiving disk 72, so that the liquid enters the spray component 7 to complete the spraying. The space distance between the lower surface of the receiving disk 72 and the quantitative filling disk 71 is less than or much less than the diameter of the spray pipe 73, and the liquid channel of the receiving disk 72 is annularly arranged, so that the liquid collected in the receiving disk 72 enters the spray component with greater pressure to complete the spraying operation; the diameter of the spray pipe 73 is smaller than the width of the cross-sectional area of ​​the arc channel 71b, so that the liquid in the spray pipe 73 has a better spraying effect.

[0032] The in-situ treatment device for compacted soil of the present invention works as follows:

[0033] When the compacted soil needs to be processed, the motor 6 is turned on to rotate forward, driving the drive shaft 21 to rotate forward, and the spiral moving rod 31 moves downward in a spiral under the action of the round rod 23b of the special-shaped part 23, driving the screw 33 and the shell 36 to penetrate into the compacted soil on the ground to complete the sampling; then the motor 6 is turned on to reverse, the screw 33 is lifted upward, and the top plate 37 and the shell 36 fixed on the top plate 37 are driven to leave the soil together through the lifting plate 34, so that the soil particles remain in the gap between the screw 33 and the shell 36; at the same time, as the screw 33 and the shell 36 are gradually lifted, the particles gradually fall from the feed port 102 into the grinding assembly 4; while the spiral moving rod 31 moves downward in a spiral, it also drives the first gear 32 to rotate, and then drives the second gear 41 and the center gear 41 in turn. 44 and the planetary gear 45 rotate, thereby causing the U-shaped upper grinding disc 43 and the U-shaped lower grinding disc 42 fixed on the planetary gear 45 to rotate relative to each other, so that the compacted soil entering the two grinding discs can be ground into soil particles of uniform particle size, and returned to the ground from the discharge channel 42a opened in the U-shaped lower grinding disc 42; when the drive shaft 21 rotates in the opposite direction, the first cam 22 in the cavity of the body 1 rotates, and drives the second cam 54 to rotate, and through the periodic rotation of the first cam 22 and the second cam 54, the organic liquid in the liquid tank 51 is sucked into the cavity through the liquid inlet pipe 52, and then discharged from the cavity into the liquid discharge pipe to flow to the spray assembly 7; under the intermittent drive of the fan-shaped teeth 23a of the special-shaped part 23, the spray assembly 7 performs quantitative spraying of the organic liquid on the ground soil.
