Technical Field

[0001] This utility model relates to the field of agricultural product testing, and in particular to a liquid sampling device for testing the quality and safety of agricultural products. Background Technology

[0002] Liquid sampling devices for agricultural product quality and safety testing are specialized equipment used to collect liquid samples related to agricultural products. Their core functions are to prevent sample contamination and ensure sample representativeness. They typically include sampling tubes, sample storage containers, and volume control components; some models incorporate aseptic design or temperature control. Available in manual and automatic versions depending on the application, they provide precise quantification, meeting the purity and consistency requirements for pesticide residue and heavy metal testing, making them a crucial tool before testing.

[0003] In existing technologies, when it is necessary to test liquid samples of fruit-type agricultural products, the agricultural product sample needs to be crushed in a crusher, and then the crushed agricultural product sample and liquid need to be separated again by a separator. The whole operation is time-consuming and labor-intensive, increasing time and labor costs. Therefore, a liquid sampling device for agricultural product quality and safety testing is proposed. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A liquid sampling device for testing the quality and safety of agricultural products includes: a protective mechanism, the protective mechanism including a protective shell, and a rotating component disposed above the protective mechanism;

[0006] A crushing mechanism located inside the protective structure, the crushing mechanism including a driving component;

[0007] A separation mechanism located inside the protective structure includes a separation plate one. A liquid flow cavity is formed between the protective shell and the separation plate one. A conical shell is provided at the bottom of the protective shell. A fixed circular plate is provided above the conical shell. A separation plate two is provided inside the conical shell. Multiple liquid outlet holes are opened on the inner wall of the separation plate two.

[0008] The above-mentioned technical solution describes an agricultural product testing and sampling device. The protective shell protects the internal components from contamination and collisions. The rotating component facilitates the opening and closing of the device to pick up and put in samples. The driving component of the crushing mechanism can drive the components to crush agricultural products. The separation mechanism achieves solid-liquid separation through the separation plate, liquid flow chamber, and liquid outlet, thereby improving the purity of the sample.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly also includes a top cover, which is disposed above the protective shell. The top of the top cover is provided with multiple locking rods, and the outside of the protective shell is provided with multiple rotating blocks.

[0011] The above technical solution features a top cover that closes the protective shell to prevent impurities from entering. The top lever cooperates with the rotating block outside the protective shell, and rotating the rotating block can fix or open the top cover, making operation convenient and facilitating quick sample preparation.

[0012] As a further description of the above technical solution:

[0013] The protective mechanism also includes a discharge pipe, which is located at the bottom of the conical shell, and a threaded cap is provided on the outside of the discharge pipe.

[0014] In the above technical solution, the discharge pipe of the protective mechanism is connected to the bottom of the conical shell, which can export the separated liquid sample. The external threaded cover can seal the discharge pipe to prevent sample leakage or contamination and ensure the sampling quality.

[0015] As a further description of the above technical solution:

[0016] The crushing assembly includes a rotating shaft, the top end of which is disposed at the driving end of the driving component. Multiple fixing rings are disposed outside the rotating shaft, and multiple crushing blades are disposed outside the fixing rings.

[0017] In the above technical solution, the rotating shaft of the crushing component is driven to rotate by a drive component, which in turn drives the external fixed ring and crushing blades to rotate, efficiently crushing agricultural product samples, allowing for more thorough subsequent liquid separation and improving sampling efficiency.

[0018] As a further description of the above technical solution:

[0019] The rotating block engages with the outside of the lever, and the top of the top cover is provided with two handles.

[0020] The above technical solution features a rotating block that engages with the lever, which securely fixes the top cover and prevents it from loosening during operation. The two handles on the top cover facilitate lifting and opening / closing by the operator, improving ease of use.

[0021] As a further description of the above technical solution:

[0022] The protective shell is provided with two sets of support feet on the outside, and friction texture is provided on the bottom of the support feet. A driving component is provided on the top cover.

[0023] The above technical solution features two sets of support feet on the outside of the protective shell to stably support the device, and the friction texture on the bottom increases the friction with the contact surface to prevent the device from sliding. The drive unit is located on the top cover, which saves internal space and facilitates the maintenance of the drive unit.

[0024] As a further description of the above technical solution:

[0025] The retaining ring is threaded to the inner wall of the rotating shaft by at least two screws, and multiple retaining rings are located on the same vertical line.

[0026] In the above technical solution, the fixing ring is connected to the inner wall of the rotating shaft with at least two screws to enhance the connection stability and prevent the fixing ring from loosening during crushing. Multiple fixing rings are on the same vertical line to ensure that the crushing blades are evenly distributed and the crushing is more uniform.

[0027] As a further description of the above technical solution:

[0028] The device also includes a plurality of bolts, which are threadedly connected to the inner walls of the protective shell and the fixed circular plate.

[0029] The above technical solution uses multiple bolts threadedly to connect the protective shell to the inner wall of the fixed circular plate, which can firmly fix the fixed circular plate, prevent the fixed circular plate from shifting during the separation process, ensure the stable operation of the separation mechanism, and improve the reliability of sampling.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, a crushing mechanism crushes fruit-type crop samples placed inside a protective shell. A motor drives the crushing mechanism, and a separation plate, powered by the drive, rotates the crushed fruit pulp and liquid together, causing the liquid to separate through small holes in the inner wall of the separation plate. This structure achieves simultaneous solid-liquid separation of the crushed fruit-type crop samples, solving the problems of time-consuming, labor-intensive, and costly processes in existing technologies where agricultural product samples are crushed in a crusher and then separated again with liquid.

[0032] 2. In this invention, a rotating block engages with the outside of the lever, and two handles on the top of the cover can be used to open or close the cover. This structure achieves convenient opening and closing of the device, solving the problem in the prior art where opening the device makes it inconvenient to feed fruit and other crop samples.
