Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a device for detecting toxic and harmful substances in soil. Background Art

[0002] When detecting toxic and harmful substances in soil, a detection device is needed. After searching, the patent with the authorization announcement number CN217238070U proposes a soil toxic and harmful substance residue detection device. The technical solution has the following problems: when sampling and testing soil, there are often more impurities and garbage in the soil, and it is not convenient to filter the sampled soil, resulting in that when testing the soil, the impurities and garbage will affect the detection of the soil, and it is easy to cause inaccurate detection, which reduces the detection effect;

[0003] In view of the above problems, the present utility model document proposes a device for detecting toxic and harmful substances in soil. Utility Model Content

[0004] The utility model provides a device for detecting toxic and harmful substances in soil, which solves the problem in the prior art that there is often a lot of impurities and garbage in the soil, and it is inconvenient to screen the sampled soil, resulting in the impurities and garbage affecting the detection of the soil during soil detection, which is prone to inaccurate detection and reduces the detection effect.

[0005] The utility model provides the following technical solutions:

[0006] A device for detecting toxic and harmful substances in soil, comprising:

[0007] A bottom plate, two supporting legs are fixedly arranged on the top side of the bottom plate, a hopper is fixedly arranged on the top of the two supporting legs, the top of the hopper is connected to a screen frame, and a soil detector for soil detection is arranged on the top of the bottom plate;

[0008] A soil screening mechanism, which is arranged inside the screen frame and is used to screen the taken soil;

[0009] The collecting mechanism is arranged on one side of the screen frame for collecting and cleaning the impurities and garbage.

[0010] In a possible design, the soil screening mechanism includes a sieve mesh, a motor, a lead screw, a threaded block, a soil spreading rake, a limit block, and a limit rod. The sieve mesh is fixedly installed on the inner wall of the sieve frame. The motor is fixedly installed on one side of the sieve frame. The output end of the motor penetrates one side of the sieve frame and extends into the interior of the sieve frame. The output end of the motor is fixed to one end of the lead screw through a coupling. The end of the lead screw away from the motor is rotatably connected to one side of the inner wall of the sieve frame through a rotating shaft. The outer wall of the lead screw is threadedly connected to the interior of the threaded block.

[0011] In a possible design, the bottom sides of the threaded block and the limit block are fixed to the top side of the soil spreading rake. The soil spreading rake is arranged on the top of the sieve mesh. The limit rod is fixedly arranged between the two sides of the inner wall of the sieve frame. A sliding hole for sliding connection with the limit rod is formed in the interior of the limit block.

[0012] In a possible design, the collection mechanism includes a through port, an impurity box, a handle, two insertion blocks, and two insertion frames. The through port is formed in one side of the inner wall of the sieve frame. The impurity box is arranged on one side of the sieve frame. The impurity box communicates with the through port. The handle is fixedly arranged on one side of the impurity box. The two insertion blocks are respectively fixedly arranged on both sides of the impurity box. Both of the two insertion blocks are slidably inserted into the interiors of the two insertion frames. Both of the two insertion frames are fixedly arranged on one side of the sieve frame.

[0013] In a possible design, a soil collection frame corresponding to the hopper is arranged between the two support legs. Sliders are fixedly arranged on both sides of the soil collection frame. A sliding groove for sliding connection with the slider is formed on one side of each support leg.

[0014] In a possible design, moving wheels are fixedly installed in a pairwise symmetric manner on the bottom side of the bottom plate.

[0015] In this application, first, the entire device is moved to the soil area to be detected by the moving wheels at the bottom of the bottom plate. The support legs firmly support the device to ensure its stability during the working process. Then, the operator puts the soil sample to be detected into the sieve frame, and the soil sample will fall onto the corresponding sieve mesh. At this time, the motor in the soil screening mechanism is started. The motor rotates and drives the lead screw to rotate synchronously through the coupling. The rotation of the lead screw causes the threaded block threadedly connected to it to move axially along the lead screw. At the same time, the limiting block is slidably connected to the limiting rod through the sliding hole inside, ensuring the stability of the soil loosening rake during the movement and preventing it from deviating from the track. The soil loosening rake fixed to the bottom sides of the threaded block and the limiting block then moves above the sieve mesh, which is conducive to turning and evenly spreading the soil, thereby promoting the screening process of soil particles passing through the sieve mesh. The fine soil particles pass through the sieve mesh and fall into the soil collection frame below under the guiding action of the hopper. This not only achieves the purpose of soil screening but also improves the soil screening efficiency. Larger impurities and garbage will be intercepted by the sieve mesh for subsequent cleaning. Thus, when taking soil samples for detection, it is convenient to screen out more impurities and garbage in the soil, improve the sample quality, prevent impurities and garbage from affecting the soil detection, and avoid inaccurate detection phenomena, thereby improving the detection effect;

[0016] During the screening process, when cleaning larger impurities and garbage on the sieve mesh, the impurities and garbage can be thrown into the impurity box through the opening provided on one side of the sieve frame. The impurity box can collect them, and the impurity box is convenient for the operator to move and clean through the handle. The insertion blocks on both sides of the impurity box are slidably inserted into the insertion frame on one side of the sieve frame, enabling the impurity box to be easily installed and disassembled, facilitating the regular unified cleaning of the collected impurities and improving the convenience of use. At the same time, the fine soil particles after screening fall into the soil collection frame. The soil collection frame slides in the chute of the support leg through the sliders on both sides, facilitating the sliding out for subsequent processing and improving the convenience. Finally, the soil sample collected in the soil collection frame is sent to the soil detector for detection. The soil detector will analyze the content of toxic and harmful substances in the soil, providing data support for soil quality assessment and improving the use effect.

[0017] In this utility model, for the device for detecting toxic and harmful substances in soil, the soil screening mechanism is conducive to turning and evenly spreading the soil, thereby promoting the screening process of soil particles passing through the sieve mesh. This not only achieves the purpose of soil screening but also improves the soil screening efficiency;

[0018] In this utility model, for the device for detecting toxic and harmful substances in soil, the collection mechanism can collect impurities and garbage, facilitating the operator to regularly and uniformly clean the collected impurities and improving the convenience of use;

[0019] In the present utility model, when sampling and detecting soil, it is convenient to screen out more impurities and garbage in the soil, improve the sample quality, prevent the impurities and garbage from affecting the soil detection, avoid inaccurate detection, and thus improve the detection effect.
