Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, specifically to a sampling device for detecting drug residues in agricultural products. Background Technology

[0002] The existing problem is that when extracting the solution after the reaction, agricultural products are easily sucked into the extraction dropper along with the solution, causing blockage inside the dropper and making it inconvenient to carry and use the sampling device.

[0003] Current agricultural product testing methods mainly involve crushing the agricultural products, reacting them with an extractant, and then extracting them onto a testing instrument. Because crushed agricultural products are relatively light, they tend to float on the surface of the extractant. When extracting the solution after the reaction, the agricultural products are easily sucked into the extraction dropper along with the solution, causing blockage inside the dropper and making it difficult to clean. Furthermore, current agricultural products need to be crushed with scissors or other knives, which makes them inconvenient to carry and use.

[0004] Furthermore, in response to the shortcomings of existing technologies, we propose a sampling device based on agricultural product drug residue detection to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sampling device for detecting drug residues in agricultural products. It solves the problem that, during the extraction of the solution after the reaction, agricultural products are easily drawn into the extraction dropper along with the solution, causing blockage inside the dropper, and the sampling device is inconvenient to carry and use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a sampling device for detecting drug residues in agricultural products, including a sampling cup and a sampling dropper, a cup lid is installed on the top of the sampling cup, a sampling rod is provided at the bottom of the cup lid, the bottom end of the sampling rod extends into the sampling cup and is fixedly connected to an annular component, the inner diameter of the annular component is adapted to the inner diameter of the sampling cup, a filter screen is fixed in the inner diameter of the annular component, and solid-liquid separation is performed in the sampling cup by pressing down the filter screen and contacting it with the bottom of the sampling cup.

[0007] Preferably, the sampling rod is hollow, with a limiting component connected to the top of the sampling rod, and a movable rod is sleeved inside the sampling rod. The bottom end of the movable rod extends to the bottom of the filter screen and is fixed with a double-bladed cutter. The top end of the movable rod passes through the cup lid and is fitted with a crossbar.

[0008] Preferably, the top side of the sampling rod is provided with a groove, and the crossbar is slidably connected inside the groove.

[0009] Preferably, the bottom of the limiting member is provided with a slot, which is adapted to the corresponding mounting crossbar to realize installation and disassembly;

[0010] Preferably, a spring is sleeved on the outer wall of the movable rod near the crossbar, and a limiting ring is provided on the inner wall of the sampling rod near the top of the cup lid. The spring is fixed to the limiting ring and provides elastic support for the crossbar.

[0011] Preferably, the annular part has a square groove at its diameter, which is adapted to the double-blade cutter.

[0012] This utility model discloses a sampling device for detecting drug residues in agricultural products, which has the following beneficial effects:

[0013] 1. By setting a sampling rod and a filter screen on the lid of the sampling cup, pressing the sampling rod can cause the filter screen to press and settle the broken agricultural products, which facilitates the extraction of the test solution and avoids the situation where agricultural products are easily extracted at the same time during the extraction process, which can easily clog the sampling dropper.

[0014] 2. By setting up a movable lever and double blades, it is easy to cut and crush agricultural products, avoiding the current problem of having to use scissors or other knives to crush agricultural products, which is less flexible and inconvenient to carry.

[0015] 3. The spring and slot are designed to allow the sampling rod to be combined, and the chopping operation after separation is more elastic. Attached Figure Description

[0022] This application provides a sampling device for detecting drug residues in agricultural products, which solves the problem that, in the current process of extracting the solution after the reaction, agricultural products are easily sucked into the extraction dropper along with the solution, causing blockage inside the dropper and making the sampling device inconvenient to carry and use.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a sampling device for detecting drug residues in agricultural products.

[0025] According to the appendix Figure 1-3 As shown, the sampling device for detecting drug residues in agricultural products includes a sampling cup 1 and a sampling dropper 6. A cup lid 2 is installed on the top of the sampling cup 1, and a sampling rod 3 is provided at the bottom of the cup lid 2. The bottom end of the sampling rod 3 extends into the sampling cup 1 and is fixedly connected to an annular part 4. The inner diameter of the annular part 4 is adapted to the inner diameter of the sampling cup 1. A filter screen 401 is fixed in the inner diameter of the annular part 4. By pressing down the filter screen 401 and contacting it with the bottom of the sampling cup 1, solid-liquid separation is performed inside the sampling cup 1.

[0026] The sampling rod 3 is hollow. The top of the sampling rod 3 is connected to a limiting member 301. A movable rod 501 is sleeved inside the sampling rod 3. The bottom end of the movable rod 501 extends to the bottom of the filter screen 401 and is fixed with a double-bladed cutter 5. The top end of the movable rod 501 passes through the cup lid 2 and is fitted with a crossbar 503.

[0027] The top side of the sampling rod 3 is provided with a sliding groove 302, and the crossbar 503 is slidably connected inside the sliding groove 302.

[0028] The bottom of the limiting member 301 is provided with a slot 303, which is adapted to the corresponding mounting crossbar 503 to realize installation and disassembly.

[0029] When the crossbar 503 is connected inside the slide groove 302, the sampling rod 3 and the movable rod 501 are used together;

[0030] When the crossbar 503 separates from the slide 302, the sampling rod 3 and the movable rod 501 are used separately, and the movable rod 501 cuts the double-blade cutter 5 at the bottom.

[0031] A spring 502 is fitted onto the outer wall of the movable rod 501 near the crossbar 503. A limiting ring is provided on the inner wall of the sampling rod 3 at a position flush with the top of the cup lid 2. The spring 502 is fixed to the limiting ring and provides elastic support to the crossbar 503.

[0032] The annular component 4 has a square groove 402 at its diameter, which is adapted to the double-blade cutter 5.

[0033] It has the following beneficial effects: By setting a sampling rod 3 and a filter screen 401 on the lid 2 of the sampling cup 1, pressing the sampling rod 3 can cause the filter screen 401 to press and settle the broken agricultural products, which facilitates the extraction of the test solution. This avoids the current situation where agricultural products are easily extracted along with the sample during the extraction process, which can easily clog the sampling dropper 6. At the same time, by setting a movable rod 501 and a double-blade cutter 5, it is easy to cut and crush agricultural products, avoiding the current problem of having to crush agricultural products with scissors or other knives, which is inconvenient to carry.
