Description

Technical Field

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention detects the soil, it first detects the impurities inside the sample soil physically, as well as the viscosity and strength of the soil, and performs a disintegration operation on the soil sample during the detection process, so that the detection liquid can contact the inside of the sample soil more fully. Through the stirring effect, the reaction efficiency between the detection liquid and the sample soil is increased, and during the detection, it is not necessary to open the detection sampling device, and it can be directly observed and judged outside, avoiding the situation that during the detection process, the sample soil cannot be processed. If the viscosity of the soil inside is too high and the hardness of the soil is too large, the detection liquid cannot fully contact the soil sample in a short time, which will reduce the reaction efficiency and the reaction is not sufficient, resulting in errors in the final detection result. 2. When the present invention simultaneously samples and detects the soil, it first pre-treats the soil sample before detection, and removes the impurities and large-sized solid particles inside the soil during the treatment. At the same time, it can also disintegrate the sample, increasing the detection efficiency after disintegration. Avoiding a large amount of impurities in the soil during the detection process of the sample, resulting in inaccurate final detection results, and the sample being in a lump and forming a whole solid during the detection, resulting in a slow reaction process in the final detection, low overall detection reaction efficiency, and during the pre-treatment process, adjusting the sampling speed and sampling state according to the specific situation of the sample after sampling to ensure the stability and efficiency of the pre-treatment of the sample.

A fixing frame rod 306 is installed at the upper middle part of the rotating rod 205. The outer part of the moving wheel 301 is installed with a mounting bushing 305 through a bearing. The mounting bushings 305 are all in a U-shaped structure. One end of the fixing frame rod 306 away from the rotating rod 205 is connected to one side of the mounting bushing 305.

When the viscosity of the soil sample after sampling is relatively large or the material of the soil sample is relatively hard, the resistance received by the processing frame rod 307 will be greater, and it will push the moving arc block 315 to slide inside the moving arc groove 312. Moreover, the displacement position of the processing frame rod 307 changes significantly, and the compression spring 313 is compressed, driving the connection guide block 316 to slide outside the coil 314, reducing the resistance of the single-phase motor 206 and increasing the rotation power of the single-phase motor 206 during use.

The treatment screen 502 is installed around the middle part of the inner cavity of the sampling frame 201. The bottom end of the inner cavity of the treatment screen 502 is arc-shaped. Mounting chutes 506 are opened on both sides of the middle part of the inner cavity of the sampling frame 201. The mounting slider 507 is slidably installed at the top end of the inner cavity of the mounting chute 506. One end of the mounting slider 507 away from the mounting chute 506 is connected to one side of the treatment screen 502. The fixing spring 508 is installed at the bottom end of the inner cavity of the mounting slider 507. The bottom end of the fixing spring 508 is connected to the bottom end of the inner cavity of the mounting chute 506. The pressure touch switch 509 is installed at the bottom end of the inner cavity of the left mounting chute 506. A plurality of rotating round blocks 503 are installed around the top end of the treatment screen 502 at equal intervals through bearings. The mounting round sleeve 505 is installed in the middle and upper part of the rotating rod 303. A plurality of pushing inclined blocks 504 are installed around the outside of the mounting round sleeve 505 at equal intervals. The inclined surface of the pushing inclined block 504 contacts the outside of the rotating round block 503. The pressure touch switch 509 is electrically connected to the control panel. The treatment screen 502 is made of a metal material, and the rotating round block 503 is cylindrical in structure. The specific implementation method is as follows: When the rotating rod 303 rotates, the surrounding pushing inclined blocks 504 are driven to rotate by the installation round sleeve 505, so that the inclined surface of the pushing inclined block 504 contacts the rotating round block 503, and the rotating round block 503 is pushed to move to the side away from the rotating rod 303, causing the upper end of the processing screen 502 to deform. When the pushing inclined block 504 is separated from the rotating round block 503, the deformed part returns to its original state. Since the speed of the generated deformation is relatively fast, the processing screen 502 can be vibrated. When the soil is lifted during the sampling operation, the soil will fall into the interior of the processing screen 502. When the processing screen 502 vibrates, the sampled soil can be separated, and the large particle impurities inside the soil can be removed. If the viscosity of the soil is relatively large, the soil cannot be separated in a short time, which will increase the weight of the processing screen 502 and cause it to move downward, driving the installation slider 507 to move to the bottom end of the inner cavity of the installation chute 506, squeezing the fixed spring 508. Later, when the weight of the processing screen 502 decreases, the compressed fixed spring 508 drives the processing screen 502 to move upward and reset. When the weight of the processing screen 502 gradually increases, the bottom end of the installation slider 507 contacts and squeezes the top end of the pressure touch switch 509. The control panel is triggered by the pressure touch switch 509 to activate the fixed electromagnet 602 to generate magnetism, generate magnetism for the connecting magnetic plate 608, and drive the movable mounting plate 603 to move downward, then drive the movable round block 605 and the limit convex block 607 to move downward, causing the limit convex block 607 to separate from the inner part of the limit notch 606. The sampling screw 203 loses its restraint force, so the sampling screw 203 will not continue to rotate and the sampling stops. When the soil sample on the upper end of the processing screen 502 decreases, the weight of the processing screen 502 will decrease. The compressed fixed spring 508 drives the installation slider 507 to move upward and drives the processing screen 502 to move upward to continue processing the sampled soil, and disconnects the circuit of the fixed electromagnet 602, causing the fixed electromagnet 602 to lose magnetism, so that the connecting magnetic plate 608 and the movable mounting plate 603 lose their restraint forces. The stretched installation spring 604 drives the movable mounting plate 603 to move upward and drives the movable round block 605 and the limit convex block 607 to move upward, causing the limit convex block 607 to be fitted and docked with the inner cavity of the limit notch 606. When the rotating rod 205 rotates, it drives the limit convex block 607 to rotate, and then drives the sampling screw 203 to rotate through the movable round block 605 and the movable mounting plate 603 to continue sampling.

[0023] Working principle: When sampling, the single-phase motor 206 is first started to drive the rotating rod 205 to rotate. The rotating rod 205 drives the sampling screw 203 to rotate inside the movable through-port 202. Then, the electric push rod 207 is started to drive the sampling frame 201 to move downward, and drive the sampling screw 203 to move downward, so that the bottom end of the sampling screw 203 is inserted into the sampled soil, and the soil is lifted up. A channel for upward transportation is formed through the movable through-port 202, and the soil is transported upward into the sampling frame 201. When the lifted soil falls, it will fall into the detection slot 204. After sampling, the soil is detected; When the rotating rod 205 rotates, it drives the fixed support rod 306 to rotate. The fixed support rod 306 drives the mounting bushing 305 and the moving wheel 301 to rotate. When the rubber ring 310 outside the moving wheel 301 rubs against the outside of the friction ring strip 302, the moving wheel 301 rotates on its own axis and drives the rotating rod 303 to rotate. The rotating rod 303 drives the fixed ring sleeve 308 and the processing support rod 307 to rotate, so as to break up the soil sample in the detection slot 204 and make the detection liquid contact the soil sample more fully, increasing the adequacy of contact with the soil during detection. When the rotating rod 303 rotates, it drives the arc-shaped scraping strip 304 to rotate at the bottom end of the inner cavity of the detection slot 204 through the fixed rod 309. Through the rotation of the arc-shaped scraping strip 304, the periphery of the inner cavity of the detection slot 204 is processed, so as to avoid impurities adhering to the inner cavity of the detection slot 204 during later use. When the viscosity of the sampled soil sample is relatively large or the material of the soil sample is relatively hard, the resistance received by the processing support rod 307 will be greater, and it will push the moving arc block 315 to slide inside the moving arc groove 312, and squeeze the compression spring 313, driving the connection guide block 316 to slide outside the coil 314, reducing the resistance of the single-phase motor 206 and increasing the rotation power of the single-phase motor 206 during use, thus improving the sampling efficiency of the sampling screw 203, and making the moving arc block 315 contact and squeeze the pressure control switch 311. Through the pressure value fed back by the pressure control switch 311, the staff can judge the state of the soil sample; When the rotating rod 303 rotates, the surrounding pushing inclined blocks 504 are driven to rotate by the mounting round sleeve 505, so that the inclined surface of the pushing inclined block 504 contacts the rotating round block 503, and the rotating round block 503 is pushed to move to the side away from the rotating rod 303, causing the upper end of the processing screen 502 to deform. When the pushing inclined block 504 separates from the rotating round block 503, the deformed part restores. Since the speed of the generated deformation is relatively fast, the processing screen 502 can be vibrated. When the soil is lifted during the sampling operation, the soil will fall into the interior of the processing screen 502. When the processing screen 502 vibrates, the sampled soil can be separated, and the large particle impurities inside the soil can be removed. If the viscosity of the soil is relatively large, the soil cannot be separated in a short time, which will increase the weight of the processing screen 502 and cause it to move downward, driving the mounting slider 507 to move to the bottom end of the inner cavity of the mounting chute 506, squeezing the fixed spring 508. Later, when the weight of the processing screen 502 decreases, the compressed fixed spring 508 drives the processing screen 502 to move upward and reset. When the weight of the processing screen 502 gradually increases, the bottom end of the mounting slider 507 contacts and squeezes the top end of the pressure touch switch 509. The control panel is triggered by the pressure touch switch 509 to activate the fixed electromagnet 602 to generate magnetism, generate magnetism for the connecting magnetic plate 608, and drive the movable mounting plate 603 to move downward, then drive the movable round block 605 and the limit convex block 607 to move downward, separating the limit convex block 607 from the inner part of the limit notch 606. The sampling screw rod 203 loses its restraint force, so the sampling screw rod 203 will not continue to rotate and the sampling stops. When the soil sample on the upper end of the processing screen 502 decreases, the weight of the processing screen 502 will decrease. The compressed fixed spring 508 drives the mounting slider 507 to move upward and drives the processing screen 502 to move upward to continue processing the sampled soil, and disconnects the circuit of the fixed electromagnet 602, causing the fixed electromagnet 602 to lose magnetism, so that the connecting magnetic plate 608 and the movable mounting plate 603 lose their restraint forces. The stretched mounting spring 604 drives the movable mounting plate 603 to move upward and drives the movable round block 605 and the limit convex block 607 to move upward, making the limit convex block 607 fit and dock with the inner cavity of the limit notch 606. When the rotating rod 205 rotates, it drives the limit convex block 607 to rotate, and then drives the sampling screw rod 203 to rotate through the movable round block 605 and the movable mounting plate 603 to continue sampling.
