DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] First embodiment:

[0025] like Figure 1-3As shown, the soil mixer for contaminated soil remediation provided by the utility model comprises: a mixing device 100, the mixing device 100 comprises a mixing box 101, the end side of the mixing box 101 is provided with a conveying port 102 and a discharge port 103, and the mixing box 101 is provided with an adjustment component 200, the adjustment component 200 comprises two positioning seats 203 symmetrically mounted on a cover plate 105, and the two positioning seats 203 are provided with bidirectional screws 204, and the middle part of the bidirectional screw 204 is provided with a rotating tooth 205 , and connecting plates 206 are sleeved on both ends of the bidirectional screw 204, the connecting plates 206 are fixedly connected to the driving motor 301 provided in the mixing assembly 300, the driving motor 301 is installed in the cavity provided by the positioning groove 208, and a rotating shaft 303 is provided at the output end of the driving motor 301, the rotating shaft 303 passes through the cavity provided by the positioning groove 208, and a stirring rod 306 is provided on the rotating shaft 303, and the staff pours the repair agent and the mixed soil into the mixing box 101 through the conveying port 102. Then, the driving motor 301 is started, and the rotating shaft 303 is rotated by the driving motor 301. The stirring and mixing work of the stirring rod 306 is realized by the rotation of the rotating shaft 303. When the moisture content of the soil to be mixed is different, the staff adjusts the spacing of the stirring rod 306 according to the soil of different textures and moisture contents. In actual use, the staff rotates the rotating gear 205, and the rotation of the rotating gear 205 realizes the rotation of the bidirectional screw 204. The rotation of the bidirectional screw 204 drives the connecting plates 206 at both ends to move left and right. Since the connecting plates 206 at both ends are fixedly connected by the combination plate 207, and the driving motor 301 is slidably installed in the positioning groove 208, when the connecting plate 206 moves, the driving motors 301 at both ends move left and right. The left and right movement of the driving motor 301 can adjust the left and right spacing of the stirring rod 306.

[0026] By using multiple parts in the adjustment component 200, the distance between the stirring rods 306 at both ends can be adjusted. By adjusting the distance between the stirring rods 306, soils of different types and states can be stirred more effectively to ensure that the contaminated soil reacts fully with the curing agent or remediation agent, thereby achieving better mixing uniformity and improving the remediation effect.

[0027] Second embodiment:

[0028] like Figure 2 , Figure 4As shown, a limit assembly 400 is also provided on the positioning plate 201, and the limit assembly 400 includes a fixed seat 401 fixedly mounted on the positioning plate 201, a screw rod 402 is provided in the fixed seat 401, and a moving block 403 is symmetrically provided in the groove provided in the fixed seat 401, and a positioning tooth 404 is provided on the moving block 403, and the positioning tooth 404 is meshed with the rotating tooth 205. In actual use, after the distance between the two ends of the stirring rod 306 is adjusted, the staff adjusts the screw rod 402, and the screw rod 402 is rotated to realize the opposite movement of the moving block 403 in the fixed seat 401, and the opposite movement of the moving block 403 is realized to realize the meshing of the positioning tooth 404 with the rotating tooth 205.

[0029] By using multiple parts in the limit assembly 400 in coordination, the positioning teeth 404 at both ends engage the rotating teeth 205, so as to limit and fix the rotating teeth 205, thereby preventing the rotating teeth 205 from rotating on their own due to the vibration of the driving motor 301 during use, and ensuring its stability through the limitation of the positioning teeth 404.

[0030] Third embodiment:

[0031] like Figure 1-2 As shown, the adjustment component 200 also includes a positioning plate 201 installed on the cover plate 105 through positioning bolts, and the positioning seat 203 is symmetrically welded on the positioning plate 201. Through the setting of the positioning plate 201, in actual use, the positioning plate 203 is detachably installed on the cover plate 105 through positioning bolts. The detachable design allows the adjustment component 200 to be quickly installed when needed and easily disassembled when not needed, providing convenience and flexibility in operation.

[0032] Fourth embodiment:

[0033] like Figure 2 As shown, the positioning plate 201 and the positioning groove 208 are both provided with a slide groove 202, and the connecting plate 206 moves left and right through the slide groove 202 provided by the positioning plate 201 and the positioning groove 208. In actual use, since a slider is provided at the bottom of the connecting plate 206, the slider provided by the connecting plate 206 is engaged with the slide groove 202 provided by the positioning plate 201 and the positioning groove 208. When the rotating tooth 205 rotates, the connecting plate 206 slides on the slide groove 202 provided by the positioning plate 201 and the positioning groove 208.

[0034] Through the slide groove 202 provided on the positioning plate 201 and the positioning groove 208 and the slider provided on the connecting plate 206, more precise positioning can be achieved through the cooperation between the slide groove 202 and the slider, ensuring that the connecting plate 206 moves more smoothly when moving left and right.

[0035] Fifth embodiment:

[0036] like Figure 2-3 As shown, a combination plate 207 is also provided at the end of the connecting plate 206, and the drive motor 301 is detachably connected and fixed to the connecting plate 206 through the combination plate 207. During actual installation, the combination plate 207 is provided, and one end of the combination plate 207 is connected to the connecting plate 206 through a positioning bolt, and the other end is fixed to the base of the drive motor 301 through a positioning bolt, thereby completing the connection and fixation of the connecting plate 206 and the drive motor 301.

[0037] By using the combined plate 207 , the driving motor 301 and the connecting plate 206 can be quickly installed and disassembled, and the stable connection between the two can be ensured by fixing with positioning bolts.

[0038] Sixth embodiment:

[0039] like Figure 3 As shown, a limit seat 304 is also provided on the rotating shaft 303, and the rotating rod 306 is embedded in the limit seat 304 and is detachably installed and fixed by a pre-tightening bolt 305. In actual use, the end of the rotating rod 306 is inserted into the cavity provided in the limit seat 304 so that the positioning holes provided in the two are aligned, and then the pre-tightening bolt 305 is used to achieve the installation and fixation of the rotating rod 306.

[0040] By providing a limited seat 304 at the end of the rotating shaft 303 and using it in conjunction with the pre-tightening bolt 305, the rotating rod 306 can be quickly installed and disassembled, and the rotating rod 306 can be quickly replaced and adjusted according to actual needs later.

[0041] Working principle: The staff pours the repair agent and the mixed soil into the mixing box 101 through the conveying port 102. Then the driving motor 301 is started, and the rotating shaft 303 is rotated by the driving motor 301, and the stirring and mixing work of the stirring rod 306 is realized by the rotation of the rotating shaft 303. When the water content of the soil to be mixed is different, the staff adjusts the spacing of the stirring rod 306 according to the soil of different textures and water contents. In actual use, the staff rotates the rotating gear 205, and the rotation of the rotating gear 205 realizes the rotation of the bidirectional screw 204. The rotation of the bidirectional screw 204 drives the connecting plates 206 at both ends to move left and right. Since the connecting plates 206 at both ends are fixedly connected by the combination plate 207, and the driving motor 301 is slidably installed in the positioning groove 208, when the connecting plate 206 moves, the driving motors 301 at both ends move left and right, and the left and right movement of the driving motor 301 realizes the adjustment of the left and right spacing of the stirring rod 306.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
