Description

Technical Field

[0001] This utility model relates to the field of heavy metal detection technology, specifically to a heavy metal detection device for agricultural products. Background Technology

[0002] Heavy metals, as discussed in terms of environmental pollution, mainly refer to metals or metalloids such as mercury, cadmium, lead, chromium, and arsenic, as well as general heavy metals with a certain degree of toxicity, such as copper, zinc, nickel, cobalt, and tin. We will briefly discuss the hazards of heavy metals from several aspects, including their naturalness, toxicity, activity and persistence, biodegradability, bioaccumulation, and additive effects on organisms.

[0003] For existing heavy metal detection devices for agricultural products, please refer to Chinese utility model patent with authorization announcement number CN219871020U, which discloses a heavy metal detection device for agricultural products, "including a support base and a detection tank that is fixedly connected to the top of the support base by welding. The top of the detection tank is rotatably connected to a tank cover by a rotating shaft. The top of the tank cover is fixedly connected to a motor by a bolt assembly. An auxiliary mechanism is provided inside the detection tank."

[0004] When the above-mentioned device is in use, the existing device uses a motor to drive the rotating blades to crush the agricultural products inside the filter barrel and stir the internal testing reagents to fully mix with the agricultural products. However, the existing device does not have an efficient mixing method during the mixing process, and other types of testing devices require separate grinding, mixing and testing. This means that multiple devices need to work simultaneously to complete a single heavy metal test. In addition, during the heavy metal component testing process, it is also necessary to avoid interference in any of the grinding, mixing and component testing stages. Therefore, protective measures are required for the equipment used in the operation process. Thus, there is a need for an agricultural product heavy metal testing device that solves the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heavy metal detection device for agricultural products, which has the advantages of integrating grinding, mixing and detection, fine grinding, and protective structure, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a heavy metal detection device for agricultural products, including a detector, a display screen installed on the outer wall of the detector, a groove formed on the outer wall of the detector, a transparent cover fitted onto the inner wall of the groove, a handle connected to the outer wall of the transparent cover, a sample container placed on the outer wall of the detector, a rotary motor installed in the inner cavity of the detector, a lower grinding disc connected to the top of the rotary motor, grinding teeth provided on the outer wall of the lower grinding disc, a placement platform connected to the inner wall of the lower grinding disc, a lower housing fitted onto the outer wall of the lower grinding disc, an upper housing provided on the top of the lower housing, a discharge port connected to the outer wall of the upper housing, an upper grinding disc fixedly fitted onto the inner wall of the upper housing, a powder outlet connected to the outer wall of the lower housing, and a vibrator installed in the inner cavity of the detector.

[0007] As a preferred embodiment of this utility model, the outer wall size of the transparent cover is adapted to the inner wall size of the groove, and the transparent cover is positioned directly above the discharge port, sample container, and detection head.

[0008] As a preferred embodiment of this utility model, a lower grinding disc is connected to the power output shaft of the rotary motor, and the lower grinding disc is positioned directly below the upper grinding disc.

[0009] As a preferred embodiment of this utility model, the inner cavity of the discharge port is connected to the inner cavity of the upper shell and the upper grinding disc, and the height of the placement platform is flush with that of the grinding teeth.

[0010] As a preferred embodiment of this invention, a sealed container is placed on top of the vibrator, and the sealed container has the same structure as the sample container.

[0011] As a preferred embodiment of this invention, the outer wall of the detector is equipped with a detection head, and a sample container is placed on top of the detection head.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This heavy metal detection device for agricultural products differs from traditional heavy metal detection devices by using the coordinated operation of upper and lower grinding discs, grinding teeth, upper grinding disc, vibrator, and detection head. It integrates grinding, mixing, and detection into a single unit, simplifying and making heavy metal detection more convenient. The device utilizes a rotary motor to rotate the lower grinding disc, allowing the upper and lower grinding discs to finely grind the agricultural raw materials into powder, facilitating the mixing and extraction of the powder for testing.

[0014] 2. This heavy metal detection device for agricultural products, through the coordinated use of the transparent cover, handle, discharge port, and detection head, ensures that during the feeding process or when the detection head is performing stripping voltammetry, the opening between the discharge port and the detection head must be sealed to prevent other objects and gases from entering the detection process and affecting the detection results. The transparent cover is then moved into the groove by holding the handle, thus providing protection during the detection and grinding processes. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4A heavy metal detection device for agricultural products includes a detector 1, a display screen 2 mounted on the outer wall of the detector 1, a groove 3 formed on the outer wall of the detector 1, a transparent cover 4 fitted onto the inner wall of the groove 3, a handle 5 connected to the outer wall of the transparent cover 4, a sample container 6 placed on the outer wall of the detector 1, a rotary motor 7 installed in the inner cavity of the detector 1, a lower grinding disc 8 connected to the top of the rotary motor 7, grinding teeth 9 on the outer wall of the lower grinding disc 8, a placement platform 10 connected to the inner wall of the lower grinding disc 8, and a lower housing 11 fitted onto the outer wall of the lower grinding disc 8. The top of the housing 11 is provided with an upper housing 12. The outer wall of the upper housing 12 is connected to a discharge port 13. The inner wall of the upper housing 12 is fixedly sleeved with an upper grinding disc 14. The outer wall of the lower housing 11 is connected to a powder outlet 15. The inner cavity of the detector 1 is equipped with a vibrator 16. The detector head 18 on the device is electrically connected to the display screen 2, so that the display screen 2 on the device can select the type of heavy metal to be detected by the detector head 18, and use the detector head 18 to perform the detection. The detection result is displayed on the surface of the display screen 2, which is convenient for the staff to observe.

[0022] In a preferred embodiment, the outer wall size of the transparent cover 4 is adapted to the inner wall size of the groove 3, and the transparent cover 4 is positioned directly above the discharge port 13, the sample container 6, and the detection head 18. By adapting the outer wall size of the transparent cover 4 to the inner wall size of the groove 3, the transparent cover 4 is placed in the inner wall of the groove 3. The transparent cover 4 covers the discharge port 13, the sample container 6, and the detection head 18 directly above them, thereby providing protection for the discharge port 13, the sample container 6, and the detection head 18 during operation.

[0023] In a preferred embodiment, a lower grinding disc 8 is connected to the power output shaft of the rotary motor 7, and the lower grinding disc 8 is located directly below the upper grinding disc 14. By connecting the lower grinding disc 8 to the power output shaft of the rotary motor 7, when the rotary motor 7 outputs rotational power, the output shaft can drive the lower grinding disc 8 to rotate, while the upper grinding disc 14 located directly above the lower grinding disc 8 remains stationary. This allows the upper grinding disc 14 to work in conjunction with the lower grinding disc 8 to grind agricultural products.

[0024] In a preferred embodiment, the inner cavity of the discharge port 13 is connected to the inner cavities of the upper shell 12 and the upper grinding disc 14, and the height of the placement platform 10 is flush with that of the grinding teeth 9. By connecting the inner cavity of the discharge port 13 to the inner cavities of the upper shell 12 and the upper grinding disc 14, when agricultural products need to be ground, they are placed into the inner cavity of the discharge port 13. The upper shell 12 and the upper grinding disc 14, which are connected to the discharge port 13, cause the agricultural products to fall directly above the placement platform 10. When the lower grinding disc 8 rotates, the centrifugal force will drive the agricultural product raw material to move towards the grinding teeth 9, thereby completing the grinding work.

[0025] In a preferred embodiment, a sealed container 17 is placed on top of the vibrator 16, and the sealed container 17 has the same structure as the sample container 6. By placing the sealed container 17 on top of the vibrator 16, the sealed container 17 on the device has the same structure as the sample container 6, but the top of the sealed container 17 is provided with a sealing cap. After the extract is placed in the inner cavity of the sealed container 17 and mixed with the agricultural product powder, the container is sealed. The vibrator 16 is used to vibrate the sealed container 17, thereby making the extract and the agricultural product powder fully mixed.

[0026] In a preferred embodiment, a detection head 18 is mounted on the outer wall of the detector 1, and a sample container 6 is placed on top of the detection head 18. By mounting the detection head 18 on the outer wall of the detector 1, the sample container 6 on the device is filled with a fully mixed component detection solution, and the detection solution is placed at the detection head 18, so that the detection head 18 can perform detection using stripping voltammetry in conjunction with a screen-printed electrode, thereby displaying the final detection result on the surface of the display screen 2.

[0027] The working principle involves the coordinated use of the upper and lower grinding discs 8, grinding teeth 9, upper grinding disc 14, vibrator 16, and detection head 18. This distinguishes the device from traditional heavy metal detection devices by integrating grinding, mixing, and detection into a single unit, allowing for simplified and convenient heavy metal testing. The rotating motor 7 drives the lower grinding disc 8 to rotate, enabling the upper grinding disc 14 to work in conjunction with the lower grinding disc 8 to finely grind the agricultural raw materials into powder. The agricultural product powder is mixed and extracted, and then tested. Through the coordinated use of the transparent cover 4, handle 5, discharge port 13, and detection head 18 on the device, it is necessary to avoid the problem of the opening not sealing the discharge port 13 and the detection head 18 when feeding materials or when the detection head 18 is conducting stripping voltammetry testing. This is to prevent other objects and gases from entering the testing process and affecting the test results. Thus, the transparent cover 4 on the device is moved into the groove 3 while holding the handle 5, so that the transparent cover 4 on the device can protect the testing and grinding process.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
