Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly relates to a soil dissolving device for soil detection and treatment. Background Art

[0002] Soil detection is a crucial environmental monitoring activity and also an important link in fields such as environmental protection, agricultural production, and geological research. By analyzing soil samples, various properties and indicators of the soil can be understood, including the soil's acidity and alkalinity (pH value), nutrient content (such as nitrogen, phosphorus, potassium, etc.), heavy metal content, organic matter content, the quantity and activity of microorganisms, etc., so as to judge the fertility status, pollution degree, and suitable crop types for planting of the soil. A soil dissolving device is a device used to dissolve soil samples for subsequent various chemical analyses and detections.

[0003] For example, the Chinese invention patent with the publication number CN112221387B provides a continuous dissolving device for soil detection. Through the nylon filter wires arranged at the bottom of the cleaning plate, it can intercept and collect floating debris such as plastic films and branches and weeds mixed in the soil, making the dissolving liquid inside the dissolving cylinder relatively clean and facilitating extraction and detection. However, when the device stirs the soil, too strong a stirring force may break soil aggregates, affect the particle distribution, and thus cause a large change in soil properties, which is not conducive to subsequent detection and treatment. Summary of the Invention

The cutting knife is outside the blade, and the blade has a better stirring and dissolving effect on the soil. When the soil sample is basically dissolved, the main rotating pipe returns to the first position, and the cutting knife changes from the second state to the first state to reduce the degree of damage to the soil and avoid that too strong stirring force will cause great changes in the soil properties.

Detailed implementation manners

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Refer to Figures 1 to 6As shown in the figure, a soil dissolving device for soil detection and treatment provided by an embodiment of the present invention includes a dissolving tank 100, an adjusting mechanism, and a plurality of stirring mechanisms. The dissolving tank 100 is vertically arranged. The adjusting mechanism includes a main rotating pipe 205 and a control rod 207. The main rotating pipe 205 and the control rod 207 are both coaxially arranged with the dissolving tank 100. The control rod 207 is rotatably arranged inside the dissolving tank 100. The main rotating pipe 205 is arranged outside the control rod 207. The main rotating pipe 205 and the control rod 207 rotate synchronously, and the main rotating pipe 205 can move up and down relative to the control rod 207. The main rotating pipe 205 has a first position and a second position. The first position of the main rotating pipe 205 is below the second position of the main rotating pipe 205. The undissolved soil sample pushes the main rotating pipe 205 to move from the first position to the second position.

[0030] The plurality of stirring mechanisms are distributed along the axial direction of the main rotating pipe 205. Each stirring mechanism includes a plurality of stirring components, and the plurality of stirring components are distributed along the circumferential direction of the main rotating pipe 205. Each stirring component includes a blade 400, a cutting knife, and an adjusting unit. The blade 400 is arranged along the radial direction of the main rotating pipe 205. The cutting knife is slidably arranged on the blade 400. The cutting knife has a first state and a second state. The first state of the cutting knife is that the cutting knife is inside the blade 400, and the second state of the cutting knife is that the cutting knife is outside the blade 400. When the main rotating pipe 205 is in the first position, the cutting knife is in the first state. When the main rotating pipe 205 is in the second position, the adjusting unit drives the cutting knife to change from the first state to the second state.

[0031] In the initial state, the main rotating pipe 205 is in the first position, and the cutting knife is in the first state. The soil sample and water are poured into the dissolving tank 100. Since the soil sample and water are in a separated state, the soil sample sinks to the bottom of the dissolving tank 100. The soil sample pushes the main rotating pipe 205 to move upward, so that the main rotating pipe 205 moves from the first position to the second position. At this time, the adjusting unit drives the cutting knife to change from the first state to the second state, and the cutting knife is outside the blade 400.

[0032] The main rotating pipe 205 is rotated. The main rotating pipe 205 drives the plurality of blades 400 to rotate synchronously. The cutting knife is outside the blade 400, and the blade 400 has a better stirring and dissolving effect on the soil. When the soil sample is basically dissolved, the main rotating pipe 205 returns to the first position, and the cutting knife changes from the second state to the first state to reduce the degree of damage to the soil and avoid that too strong stirring force will cause great changes in the soil properties.

[0033] In this embodiment, each blade 400 includes a plurality of housings 402, and the plurality of housings 402 are sequentially distributed along the radial direction of the main rotating pipe 205. The four side walls of the housing 402 are respectively a first side, a second side, a third side, and a fourth side. Among them, the first side and the second side of the housing 402 are sequentially distributed along the radial direction of the main rotating pipe 205. The first side of the housing 402 abuts against the second side of the adjacent housing 402. The third side and the fourth side of the housing 402 are sequentially distributed along the tangential direction of the main rotating pipe 205.

[0034] The cutting knife includes a plurality of blades 403. Two blades 403 are arranged in each housing 402. The two blades 403 are respectively arranged on the third side and the fourth side of the housing 402. Slits 408 are formed on both the third side and the fourth side of the housing 402, and the blade 403 can move along the direction from the third side to the fourth side of the housing 402.

[0035] In this embodiment, a plurality of spiral grooves 2051 are formed on the peripheral wall of the main rotating pipe 205. A first redirecting wheel 404 is rotatably arranged on one side of each blade 403 inside the housing 402. Two limiting units are arranged in each housing 402, and the two limiting units are distributed along the direction from the third side to the fourth side of the housing 402. Each limiting unit includes a second redirecting wheel 405 and a third redirecting wheel 406. The second redirecting wheel 405 and the third redirecting wheel 406 are both rotatably arranged inside the housing 402. The second redirecting wheel 405 and the third redirecting wheel 406 are distributed along the direction from the first side to the second side of the housing 402, and the second redirecting wheel 405 and the third redirecting wheel 406 are respectively located on both sides of the first redirecting wheel 404.

[0036] Each adjusting unit is arranged in one blade 400. Each adjusting unit includes a first pull rope 401 and a second pull rope 409. 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 housing 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 housing 402. The first pull rope 401 and the second pull rope 409 both sequentially bypass the first redirecting wheel 404, the second redirecting wheel 405, and the third redirecting wheel 406 inside each housing 402. The first pull rope 401 first abuts against the side of the second redirecting wheel 405 close to the outside of the housing 402, then abuts against the side of the first redirecting wheel 404 close to the inside of the housing 402, and finally abuts against the side of the third redirecting wheel 406 close to the outside of the housing 402. One end of the first pull rope 401 is fixedly connected to one end of the second pull rope 409. The other ends of the first pull rope 401 and the second pull rope 409 both pass through a spiral groove 2051 and are fixedly connected to the control rod 207.

[0037] When the main rotating pipe 205 moves from the first position to the second position, the main rotating pipe 205 drives multiple blades 400 to move upward synchronously. The first pulling rope 401 and the second pulling rope 409 are tightened. The lengths of the first pulling rope 401 and the second pulling rope 409 inside the blade 400 become shorter. The first pulling rope 401 and the second pulling rope 409 push the first redirecting wheel 404 to move outward, causing the blade 403 to extend out of the housing 402, and the cutting tool changes from the first state to the second state.

[0038] In this embodiment, each adjusting unit further includes a plurality of tension springs 407. Each tension spring 407 connects the housing 402 and a blade 403. When the cutting tool changes from the first state to the second state, the tension spring 407 is stretched. When the main rotating pipe 205 moves from the second position to the first position, under the action of the tension spring 407, the cutting tool changes from the second state to the first state.

[0039] In this embodiment, the adjusting mechanism further includes a turntable 206 and a compression spring 208. The turntable 206 and the dissolving tank 100 are coaxially arranged. The turntable 206 is rotatably arranged in the dissolving tank 100 about its own axis. A first sliding groove is formed on the turntable 206. The first sliding groove is vertically arranged. The upper end of the main rotating pipe 205 is slidably arranged in the first sliding groove. The compression spring 208 connects the turntable 206 and the main rotating pipe 205.

[0040] In this embodiment, a first retaining ring is fixedly arranged at the lower end of the first sliding groove. The first retaining ring and the turntable 206 are coaxially arranged. A second retaining ring is fixedly arranged at the upper end of the main rotating pipe 205. The second retaining ring and the main rotating pipe 205 are coaxially arranged. When the main rotating pipe 205 is in the first position, the first retaining ring and the second retaining ring are in contact. The first retaining ring and the second retaining ring are used to prevent the main rotating pipe 205 and the turntable 206 from separating from each other. A fixing block is arranged on the first retaining ring. A second sliding groove is formed on the outer side of the main rotating pipe 205. The second sliding groove is vertically arranged. The fixing block is slidably arranged in the second sliding groove. Therefore, the main rotating pipe 205 and the turntable 206 can rotate synchronously.

[0041] In this embodiment, a tightening nut 204 is fixedly arranged at the upper end of the control rod 207. The tightening nut 204 is in threaded cooperation with the turntable 206. When the turntable 206 rotates, it drives the control rod 207 to rotate synchronously.

[0042] In this embodiment, a soil dissolving device for soil detection and treatment further includes a driving mechanism. The driving mechanism includes a motor 202. The motor 202 is fixedly arranged on the dissolving tank 100. A first gear 2021 is fixedly arranged on the output shaft of the motor 202. A second gear 2061 is fixedly arranged on the turntable 206. The second gear 2061 and the turntable 206 are coaxially arranged. The second gear 2061 meshes with the first gear 2021.

[0043] Start the motor 202. The motor 202 drives the first gear 2021 to rotate. The first gear 2021 drives the turntable 206 to rotate through the second gear 2061. The turntable 206 drives the main rotating pipe 205 to rotate synchronously. The turntable 206 drives the control rod 207 to rotate synchronously through the tightening nut 204.

[0044] In this embodiment, the dissolution tank 100 includes a barrel body 102 and a barrel cover 103. The barrel body 102 is vertically arranged. A clamping groove 101 is formed on the barrel body 102. An elastic buckle 203 is arranged on the barrel cover 103. The elastic buckle 203 cooperates with the clamping groove 101 to connect the barrel body 102 and the barrel cover 103.

[0045] In this embodiment, a handle 201 is fixedly arranged on the barrel cover 103.

[0046] The working process of a soil dissolution device for soil detection and treatment includes the pre-dissolution stage and the post-dissolution stage.

[0047] Pre-dissolution stage: In the initial state, the main rotating pipe 205 is in the first position and the cutting knife is in the first state. Open the barrel cover 103, pour the soil sample and water into the dissolution tank 100, and then snap the elastic buckle 203 into the clamping groove 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 pipe 205 to move upward. At this time, the main rotating pipe 205 moves upward relative to the control rod 207, and the compression spring 208 is compressed.

[0048] The main rotating pipe 205 drives a plurality of blades 400 to move upward synchronously. The first pull rope 401 and the second pull rope 409 are tightened. The lengths of the first pull rope 401 and the second pull rope 409 inside the blade 400 become 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 housing 402, and the cutting knife changes from the first state to the second state, and the tension spring 407 is stretched.

[0049] At the same time, start the motor 202. The motor 202 drives the first gear 2021 to rotate. The first gear 2021 drives the turntable 206 to rotate through the second gear 2061. The turntable 206 drives the main rotating pipe 205 to rotate synchronously. The turntable 206 drives the control rod 207 to rotate synchronously through the tightening nut 204. At this time, the combination between two adjacent housings 402 is tighter. At the same time, the blade 403 is outside the housing 402, so that in the pre-dissolution stage, the blade 400 has a better stirring and dissolution effect on the soil.

[0050] Post-dissolution stage: When the soil sample is basically dissolved and the soil sample and water are mixed, under the action of the compression spring 208, the main rotating pipe 205 returns to the first position. At this time, it is in the post-dissolution stage.

[0051] Under the action of the tension spring 407, the blade 403 moves into the housing 402 again, and the cutting tool changes from the second state to the first state. At this time, the connection between two adjacent housings 402 is no longer tight. Thus, in the later stage of dissolution, the rigidity of the blade 400 is weakened, and the degree of damage to the soil is reduced, thereby avoiding great damage to the soil properties caused by the blade 400 with greater rigidity.

[0052] In the later stage of dissolution, the motor 202 rotates forward and reverses reciprocally, and the motor 202 drives the main rotating pipe 205 and multiple blades 400 to rotate forward and reverse synchronously. During the forward and reverse rotation of the blade 400, since the connection between two adjacent housings 402 is loose, there will be an opening and closing process between the contact surfaces of two adjacent housings 402. That is, during the deformation of the blade 400, turbulence will be formed between two adjacent housings 402, thereby enhancing the dissolution effect to a certain extent.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
