[0005] In view of the above problems, the present utility model document proposes a detection device for the content of isooctyl acrylate in soil and sediment. Summary of the Utility Model

[0006] The utility model provides a detection device for the content of isooctyl acrylate in soil and sediment, which solves the disadvantages in the prior art that it is inconvenient to directly sample soil and sediment, and another sampling tool is needed to shovel soil and sediment, which not only increases the labor intensity and tediousness, but also reduces the convenience.

[0007] The utility model provides the following technical solutions:

[0008] A detection device for the content of isooctyl acrylate in soil and sediment, comprising:

[0009] A bottom plate, on the top of the bottom plate is provided a detector body, on the top side of the bottom plate is fixedly provided a fixed box, the inner wall of the fixed box is fixedly installed with a sieve, on one side of the fixed box is provided a collection groove, and inside the collection groove is slidably connected a collection box corresponding to the sieve;

[0010] A sampling mechanism, which is arranged on the bottom plate and is used for shoveling and sampling soil and sediment in the soil;

[0011] A knocking mechanism, which is arranged on the fixed box and is used for knocking and sieving the sieve.

[0012] In a possible design, the sampling mechanism includes a support block, a first motor, a lifting lead screw, a support groove, a threaded block, a sampling shovel, and a through hole. The support block is fixedly arranged on the top side of the bottom plate. A sliding groove for the threaded block to slide is formed on one side of the support block. The sampling shovel is fixedly arranged on one side of the threaded block and is used for shoveling soil and sediments in the soil.

[0013] In a possible design, the first motor is fixedly installed on the top of the support block. The output end of the first motor penetrates the top side of the support block and extends into the inside of the sliding groove. The output end of the first motor is fixed to the top end of the lifting lead screw through a coupling. The bottom end of the lifting lead screw is rotatably connected to the bottom side of the inner wall of the support groove through a rotating shaft. The support groove is formed on the top side of the bottom plate. A through hole for the sampling shovel to penetrate is formed on the top side of the bottom plate.

[0014] In a possible design, the knocking mechanism includes a fixed frame, a second motor, a reciprocating lead screw, a fixed plate, two reciprocating plates, two driving rods, and two knocking balls. The fixed frame is fixedly arranged on the top side of the fixed box. The second motor is fixedly installed on the top of the fixed frame. The output end of the second motor penetrates the top side of the fixed frame and extends to the bottom of the fixed frame. The output end of the second motor is fixed to the top end of the reciprocating lead screw through a coupling. The fixed plate is fixedly arranged between the two sides of the inner wall of the fixed box.

[0015] In a possible design, a lead screw nut is threadedly connected to the outer wall of the reciprocating lead screw. The two reciprocating plates are fixedly arranged on the outer wall of the lead screw nut. The two driving rods are respectively fixedly arranged on the bottom sides of the two reciprocating plates. Two sliding holes for the driving rods to slide are formed inside the fixed plate. The two knocking balls are respectively fixedly arranged at the bottom ends of the two driving rods and are used for knocking and screening the sieve mesh.

[0016] In a possible design, two push hands are fixedly arranged on the top side of the bottom plate. Four moving wheels are fixedly installed in a pairwise symmetric manner on the bottom side of the bottom plate.

[0017] In this application, during use, first move the bottom plate to a suitable sampling area through the moving wheels at its bottom. The detector body on the top of the bottom plate is ready for subsequent detection of the content of isooctyl acrylate. Then start the first motor in the sampling mechanism to run. The first motor drives the lifting screw rod to rotate in the support groove. Since the threaded block is threadedly connected to the lifting screw rod and is restricted by the sliding groove of the support block, the threaded block will move up and down along the sliding groove. When the threaded block moves downward, the sampling shovel fixed on it will pass through the through hole on the top of the bottom plate and penetrate into the soil. At this time, the whole device can be pushed by the pusher to facilitate further operation for sampling. Under the action of movement, the sampling shovel can shovel and sample the soil and the sediment contained in the soil to facilitate subsequent processing and detection. After sampling, the first motor rotates in the reverse direction to drive the sampling shovel and the sample back to the initial position, thus achieving the purpose of convenient sampling. Therefore, when detecting the soil and sediment, it is convenient to directly sample the soil and sediment, and there is no need to take another sampling tool to shovel the soil and sediment, avoiding increasing the labor intensity and complexity, and thus improving the convenience;

[0018] Next, scrape the soil inside the sampling shovel into the corresponding fixed box, and at the same time it will fall onto the screen in the fixed box. The soil can be screened through the screen. Then, the sediment in the soil will be screened onto the screen, and the remaining soil will fall into the collection box placed in the collection groove on one side of the fixed box in advance. The soil can be collected and stored through the collection box to facilitate later sample detection. At the same time, start the second motor in the knocking mechanism to run. The second motor drives the reciprocating screw rod to rotate in the fixed frame. Since the outer wall of the reciprocating screw rod is threadedly connected to the screw nut, and the screw nut is fixedly connected to two reciprocating plates, the reciprocating plates will move back and forth along the direction of the reciprocating screw rod. The driving rod at the bottom side of the reciprocating plate slides in the sliding hole of the fixed plate and drives the knocking ball to move up and down, which is beneficial to knocking and screening the screen, thus helping to enhance the screening effect of the screen, accelerating the screening efficiency, and improving the applicability. Finally, send the screened soil sample and sediment sample into the detector body for detection of the content of isooctyl acrylate, improving the use effect.

[0019] In this utility model, for the detection device for the content of isooctyl acrylate in soil and sediment, the sampling mechanism is used to shovel and sample the soil and the sediment contained in the soil to facilitate subsequent processing and detection, thus achieving the purpose of convenient sampling;

[0020] In this utility model, for the detection device for the content of isooctyl acrylate in soil and sediment, the knocking mechanism is beneficial to knocking and screening the screen, thus helping to enhance the screening effect of the screen, accelerating the screening efficiency, and improving the applicability;

[0021] In the present utility model, when detecting soil and sediment, it is convenient to directly sample the soil and sediment, so there is no need to take another sampling tool to shovel the soil and sediment, avoiding increasing the labor intensity and complexity, and thus improving the convenience degree.
