Description

Technical Field

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

[0002] Conducting pesticide residue testing on agricultural products is essential to safeguard public food safety and health, preventing health risks such as poisoning from consuming agricultural products with excessive pesticide residues. Simultaneously, it helps regulate the agricultural product market, improve product quality, enhance consumer confidence, and promote the healthy development of the agricultural industry. Furthermore, it helps my country's agricultural products overcome green barriers in international trade, improving their competitiveness in the international market, and is of great significance to ensuring sustainable agricultural development and national food security. To improve the convenience of testing personnel, specialized sampling devices can be used for agricultural product sampling.

[0003] A portable sampling device for detecting pesticide residues in agricultural products, disclosed in authorization announcement number CN214952278U, includes a sampling rod with a sampling column threadedly connected to it. Sampling spoons are fixed to both sides of the sampling rod and the sampling column. The user holds the rod and inserts a needle into the cucurbitaceous agricultural product, allowing the sampling rod and sampling column to be inserted into the product. The sampling spoons on the sampling column and rod are distributed at different positions inside the product. Rotating the sampling column and rod causes the sampling spoons to rotate inside the product, scraping the fleshy parts of the product into the sampling spoons. The sampling rod is then pulled out, collecting samples from different parts of the product within the sampling spoons, thus completing the sampling process. This facilitates the detection of pesticide residues at different locations in the product. The sampling rod, sampling column, and holding rod can be separated by rotating the sampling column and the holding rod, reducing the overall length and making the device easy to carry.

[0004] However, this utility model has limitations in rapidly sampling deeper parts of agricultural products, and it lacks convenient storage and protection measures, making sample storage inconvenient. Furthermore, its sharp points can easily cause puncture wounds, posing a safety risk. Therefore, we propose a sampling device for detecting pesticide residues in agricultural products, which solves the problems of difficult deep sampling, inconvenient sample storage, and insufficient safety associated with this utility model, thus improving its practical effectiveness and safety.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A sampling device for detecting pesticide residues in agricultural products includes a cylindrical hollow cylinder 100, a sampling mechanism inside the cylindrical hollow cylinder 100, an annular support 101 fixedly installed at the bottom end of the cylindrical hollow cylinder 100, a protective cover 102 threadedly connected to the outer side of the annular support 101, and a sample storage mechanism inside the protective cover 102.

[0025] In this embodiment, preferably, the sampling mechanism includes a threaded rod 200 and a movable frame 201. The bottom end of the threaded rod 200 passes through the movable frame 201 and is threadedly connected to it. A fixing block 202 is fixedly installed at the top of the cylindrical hollow cylinder 100. The top end of the threaded rod 200 passes through the fixing block 202 and is rotatably connected to it. Limiting rings 203 are provided on both sides of the movable frame 201. Limiting slide rods 204 are slidably connected through the inside of the limiting rings 203. The two ends of the limiting slide rods 204 are fixedly connected to the inner wall of the cylindrical hollow cylinder 100. A sampling rod 205 is detachably and movably installed at the bottom of the movable frame 201. 5. A spiral sampling spoon 206 is provided on the outside. When in use, the cylindrical hollow cylinder 100 is separated from the protective cover 102 by rotating the protective cover 102. Then, the annular support seat 101 at the bottom of the cylindrical hollow cylinder 100 is placed on the surface of the agricultural product to be sampled. Hold the cylindrical hollow cylinder 100 with one hand and rotate the rotating handle 212 clockwise with the other hand to make the threaded rod 200 rotate. Since the threaded rod 200 is threadedly connected to the movable frame 201, and the movable frame 201 achieves a circumferential limiting effect on both sides through the limiting ring 203 and the limiting slide rod 204, the movable frame 201 moves downward along the limiting slide rod 204. An installation chamber 207 is provided at the bottom of the movable frame 201. A drive motor 208 is fixedly installed inside the installation chamber 207. The output end of the drive motor 208 is engaged with the top of the sampling rod 205. A storage battery 209 and a switch button 210 are fixedly installed on one side of the cylindrical hollow cylinder 100. The switch button 210 is electrically connected to the storage battery 209, and the drive motor 208 is electrically connected to the switch button 210. In use, by starting the drive motor 208, the output end of the drive motor 208 drives the spiral sampling spoon 206 to rotate continuously. As the movable frame 201 moves down continuously, the spiral sampling spoon 206 is driven to penetrate into the agricultural product to achieve a rapid sampling effect.

[0026] In this embodiment, preferably, the sample storage mechanism includes a storage cavity 300 and an annular cover 301. The storage cavity 300 is disposed inside the protective cover 102, and the annular cover 301 is fixedly installed on the top of the storage cavity 300. A silicone sealing strip 302 is fixedly disposed at the bottom of the annular cover 301, and a convenient lifting ring 303 is fixedly disposed at the top of the annular cover 301. Through the storage cavity 300 disposed inside the protective cover 102, the retrieved sample can be placed into the storage box 300 for storage. Three partition plates 304 are fixedly disposed inside the storage cavity 300. The three partition plates 304 are evenly distributed in an array inside the storage cavity 300 with the center of the annular cover 301 as the base point. Through the arrangement of the three partition plates 304, the storage cavity 300 can be divided into multiple storage spaces, thereby achieving the effect of classified storage.

[0027] In this embodiment, preferably, the inner wall of the protective cover 102 is provided with an internal thread, and the outer wall of the annular support 101 is provided with an external thread corresponding to the internal thread, so as to facilitate the easy installation and removal of the protective cover 102. A conical groove 305 is provided at the center of the annular cover 301, and the conical groove 305 is located directly below the sampling rod 205.

[0028] In this embodiment, preferably, a limiting block 211 is fixedly provided at the bottom of the threaded rod 200, and a rotating handle 212 is fixedly provided at its top. There are two limiting slide rods 204, which are symmetrically arranged with respect to the threaded rod 200 to maintain the movement stability of the movable frame 201. The bottom end of the sampling rod 205 is designed with a conical tip to facilitate insertion into the agricultural product for sampling.

[0029] In this embodiment, a sampling device for detecting pesticide residues in agricultural products is used by first separating the cylindrical hollow cylinder 100 from the protective cover 102 by rotating the protective cover 102. Then, the annular support 101 at the bottom of the cylindrical hollow cylinder 100 is placed on the surface of the agricultural product to be sampled. One hand holds the cylindrical hollow cylinder 100, and the other hand rotates the rotating handle 212 clockwise, causing the threaded rod 200 to rotate. Since the threaded rod 200 is threadedly connected to the movable frame 201, and the movable frame 201 is circumferentially limited on both sides by the limiting ring 203 and the limiting slide rod 204, the movable frame 201 moves downward along the limiting slide rod 204. At this time, the drive motor 208 is started by the switch button 210, and the output of the drive motor 208... The spiral sampling spoon 206 rotates continuously. As the movable frame 201 moves downward, the spiral sampling spoon 206 penetrates deep into the agricultural product to achieve rapid sampling. After sampling, the drive motor 208 is turned off by pressing the switch button 210 again. Then, the rotating handle 212 is turned counterclockwise, causing the movable frame 201 to move upward and pull the spiral sampling spoon 206 out of the agricultural product, thus taking out the sample material. The annular cover 301 is opened, and the sample material is placed into the corresponding storage cavity 300. When multiple agricultural products need to be sampled, or when multiple sample materials are needed, different samples can be stored separately through the three partitions 304 set inside the storage cavity 300. Finally, the annular cover 301 is closed.
