[0031] Each adjustment unit is arranged in a blade 400, and each adjustment unit includes a first pull rope 401 and a second pull rope 409, and the first pull rope 401 and the second pull rope 409 are distributed along the direction from the third side to the fourth side of the shell 402. The first pull rope 401 and the second pull rope 409 are both arranged along the direction from the first side to the second side of the shell 402. The first pull rope 401 and the second pull rope 409 are both passed around the first redirecting wheel 404, the second redirecting wheel 405 and the third redirecting wheel 406 in each shell 402 in sequence, and the first pull rope 401 first abuts against the side of the second redirecting wheel 405 close to the outside of the shell 402, then abuts against the side of the first redirecting wheel 404 close to the inside of the shell 402, and finally abuts against the side of the third redirecting wheel 406 close to the outside of the shell 402. One end of the first pull rope 401 is fixedly connected to one end of the second pull rope 409 , and the other end of the first pull rope 401 and the other end of the second pull rope 409 are both fixedly connected to the control rod 207 after passing through a spiral groove 2051 .

[0032] When the main rotating tube 205 moves from the first position to the second position, the main rotating tube 205 drives multiple blades 400 to move upward synchronously, the first pull rope 401 and the second pull rope 409 are tightened, the length of the first pull rope 401 and the second pull rope 409 inside the blade 400 becomes shorter, and the first pull rope 401 and the second pull rope 409 push the first redirecting wheel 404 to move outward, so that the blade 403 extends out of the shell 402, and the cutting knife changes from the first state to the second state.

The upper end of the main rotating tube 205 is arranged in the first slide groove so as to slide up and down. The compression spring 208 connects the rotating disk 206 and the main rotating tube 205.

[0035] In this embodiment, a first retaining ring is fixedly provided at the lower end of the first slide groove, and the first retaining ring and the turntable 206 are coaxially arranged. A second retaining ring is fixedly provided at the upper end of the main rotating tube 205, and the second retaining ring and the main rotating tube 205 are coaxially arranged. When the main rotating tube 205 is in the first position, the first retaining ring and the second retaining ring abut against each other.

A fixed block is provided on the first retaining ring, and a second slide groove is provided on the outer side of the main rotating tube 205. The second slide groove is vertically arranged, and the fixed block is slidably arranged in the second slide groove, so that the main rotating tube 205 and the turntable 206 can rotate synchronously.

[0036] In this embodiment, a tightening nut 204 is fixedly provided on the upper end of the control rod 207 , and the tightening nut 204 and the rotating disk 206 are threadedly matched, so that when the rotating disk 206 rotates, the control rod 207 is driven to rotate synchronously.

[0037] In this embodiment, a soil dissolution device for soil detection and treatment further includes a driving mechanism, which includes a motor 202, the motor 202 is fixedly disposed on the dissolution tank 100, and a first gear 2021 is fixedly disposed on the output shaft of the motor 202. A second gear 2061 is fixedly disposed on the rotating disk 206, the second gear 2061 and the rotating disk 206 are coaxially disposed, and the second gear 2061 and the first gear 2021 are meshed.

[0038] The motor 202 is started, the motor 202 drives the first gear 2021 to rotate, and the first gear 2021 drives the rotating disk 206 to rotate through the second gear 2061. The rotating disk 206 drives the main rotating tube 205 to rotate synchronously, and the rotating disk 206 drives the control rod 207 to rotate synchronously by tightening the nut 204.

[0039] In this embodiment, the dissolving tank 100 includes a cylinder body 102 and a cylinder cover 103. The cylinder body 102 is vertically arranged, a slot 101 is opened on the cylinder body 102, and an elastic buckle 203 is arranged on the cylinder cover 103. The elastic buckle 203 cooperates with the slot 101 to connect the cylinder body 102 and the cylinder cover 103.

[0040] In this embodiment, a handle 201 is fixedly provided on the cylinder cover 103 .

[0041] The working process of a soil dissolution device for soil detection and treatment includes an early dissolution period and a late dissolution period.

[0042] Pre-dissolution: In the initial state, the main rotating tube 205 is in the first position and the cutting knife is in the first state. The cylinder cover 103 is opened, and the soil sample and water are poured into the dissolution tank 100, and then the elastic buckle 203 is snapped into the card slot 101. Since the soil sample and water are in a separated state, the soil sample sinks to the bottom of the dissolution tank 100. The soil sample pushes the main rotating tube 205 to move upward, and at this time the main rotating tube 205 moves upward relative to the control rod 207, and the compression spring 208 is compressed.

[0043] The main rotating tube 205 drives multiple blades 400 to move upward synchronously, the first pull rope 401 and the second pull rope 409 are tightened, the length of the first pull rope 401 and the second pull rope 409 inside the blade 400 becomes shorter, the first pull rope 401 and the second pull rope 409 push the first redirecting wheel 404 to move outward, so that the blade 403 extends out of the shell 402, the cutting knife changes from the first state to the second state, and the tension spring 407 is stretched.

[0044] At the same time, the motor 202 is started, the motor 202 drives the first gear 2021 to rotate, and the first gear 2021 drives the rotating disk 206 to rotate through the second gear 2061. The rotating disk 206 drives the main rotating tube 205 to rotate synchronously, and the rotating disk 206 drives the control rod 207 to rotate synchronously by tightening the nut 204. At this time, the combination between the two adjacent shells 402 is tighter, and the blade 403 is outside the shell 402, so that in the early stage of dissolution, the blade 403 has a better stirring and dissolving effect on the soil.

[0045] Late dissolution stage: When the soil sample is basically dissolved and the soil sample is mixed with water, the main rotating tube 205 returns to the first position under the action of the compression spring 208. This is the late dissolution stage.

[0046] Under the action of the tension spring 407, the blade 403 moves into the housing 402 again, and the cutting blade changes from the second state to the first state. At this time, the connection between the two adjacent housings 402 is no longer tight, so that in the later stage of dissolution, the rigidity of the blade 400 is weakened, and the degree of damage to the soil is weakened, thereby avoiding the blade 400 with greater rigidity from causing greater damage to the soil properties.

[0047] In the later stage of dissolution, the motor 202 is made to rotate forward and reversely, and the motor 202 drives the main rotating tube 205 and the plurality of blades 400 to rotate forward and reverse synchronously. During the process of the blades 400 rotating forward and reversely, due to the loose connection between the two adjacent shells 402, there will be an opening and closing process between the contact surfaces of the two adjacent shells 402. That is, during the deformation process of the blades 400, turbulence will be formed between the two adjacent shells 402, thereby enhancing the dissolution effect to a certain extent.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
