Technical Field
[0001] This utility model relates to the field of agricultural product testing equipment technology, and more specifically, to a sampling device for detecting pesticide residues in agricultural products. Background Technology
[0002] Agricultural products are necessities in people's lives. Before being sold, agricultural products need to be tested. In order to increase yield during the production process, some chemical fertilizers and additives are used. In order to ensure food safety, it is necessary to test for harmful elements and whether some chemical elements exceed the standards.
[0003] In agricultural product testing, agricultural products are typically crushed, mixed with buffer solution, and then shaken or stirred to obtain a test solution. The test solution is then tested by an instrument. However, existing agricultural product sampling devices only address the crushing process to extract more juice from the agricultural products. To ensure accuracy, the sample volume needs to be kept constant for clearer comparisons. Weighing is usually performed before sampling. For testing large quantities of agricultural products, this process is cumbersome, labor-intensive, and inconvenient for testing personnel.

[0005] The equipment has certain defects during use. For example, when adding crushed crops into the mixing chamber, the equipment needs to be stopped, which affects the efficiency of the equipment. At the same time, it is difficult to remove the crops from the equipment, and the presence of residue will affect subsequent sampling. Utility Model Content
[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a sampling device for detecting pesticide residues in agricultural products, so as to solve the problems in the background technology.

[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 of the present utility model;
[0021] Please see Figures 1-3 This utility model discloses a sampling device for detecting pesticide residues in agricultural products, comprising a processing box 1. The processing box 1 has a partitioned cavity 101 and a mixing cavity 102 inside. The partitioned cavity 101 is located at the top of the mixing cavity 102 and communicates with its interior. A drive motor 2 is fixedly mounted on the front of the processing box 1. The output shaft of the drive motor 2 passes through and extends into the partitioned cavity 101. Evenly distributed partitions 3 are fixedly connected to the output shaft of the drive motor 2. A stirring motor 4 is fixedly mounted on the front of the processing box 1. The output shaft of the stirring motor 4 passes through and extends into the mixing cavity 101. Inside the 2, the output shaft of the stirring motor 4 is fixedly connected to a uniformly distributed stirring shaft 5. The front of the processing box 1 is fixedly installed with a discharge pipe 6. The right side of the processing box 1 is fixedly installed with an addition pipe 7. The addition pipe 7 passes through and extends into the interior of the processing box 1. The top of the processing box 1 is fixedly installed with a crushing box 8. The top of the crushing box 8 is fixedly installed with a crushing motor 9. The output shaft of the crushing motor 9 passes through and extends into the interior of the crushing box 8. The output shaft of the crushing motor 9 is fixedly connected to a uniformly distributed crushing blade 10. The right side of the crushing box 8 is fixedly connected to a feed hopper 11 that communicates with its interior.
[0022] The bottom of the processing box 1 is provided with a mounting base 12, the processing box 1 is hinged to the top of the mounting base 12, an electric push rod 13 is fixedly mounted on the mounting base 12, a rotating rod 14 is fixedly mounted on the output end of the electric push rod 13, and an inclined plate 15 is fixedly connected to the bottom of the processing box 1, with the rotating rod 14 located at the bottom of the inclined plate 15.
[0023] The sides of the partition 3 away from the output shaft of the drive motor 2 are all in contact with the inner wall of the partition cavity 101; the stirring shaft 5 has evenly distributed air holes 501.
[0024] When it is necessary to conduct pesticide residue testing and sampling of agricultural products, the user adds the agricultural products to be tested into the crushing box 8 through the feed hopper 11, and then starts the crushing motor 9. The output shaft of the crushing motor 9 drives the evenly distributed crushing blades 10 to rotate, and crushes the agricultural products.
[0025] The crushed crops fall into the partition chamber 101 of the processing box 1. The drive motor 2 is turned on and the output shaft of the drive motor 2 drives the fixedly connected partition 3 to rotate inside the partition chamber 101. Since the side of the partition 3 away from the output shaft of the drive motor 2 is in contact with the inner wall of the partition chamber 101, the partition 3 forms multiple chambers inside the partition chamber 101 during the rotation process, and the crushed crops enter these chambers.
[0026] As the partition 3 rotates, the chamber rotates to a position connected to the mixing chamber 102. The crops fall into the mixing chamber 102, and the mixing chamber 102 is filled with reaction liquid through the addition tube 7. At the same time, the stirring motor 4 is started, and the output shaft of the stirring motor 4 drives the stirring shaft 5 to rotate, stirring and mixing the crops and reaction liquid in the mixing chamber 102. The evenly distributed pores 501 on the stirring shaft 5 help to improve the mixing effect.
[0027] During the feeding process described above, the crushing box 8 can continuously crush the newly added crops at the top. When the material in the mixing chamber 102 needs to be discharged, the discharge pipe 6 is opened. If more thorough discharge is required, the electric push rod 13 can be activated. The output end of the electric push rod 13 pushes the rotating roller 14. Since the processing box 1 is hinged to the top of the mounting base 12 and has an inclined plate 15 at the bottom, the rotating roller 14 pushes the inclined plate 15 to tilt the processing box 1, which facilitates the discharge of materials.
[0028] After the material is discharged from the bottom mixing chamber 102, the partition 3 continues to rotate, causing the new chamber containing the crushed crops to rotate to a position connected to the mixing chamber 102. The crops directly enter the mixing chamber 102, reducing the time required for further crushing and improving sampling efficiency.
[0029] In this invention, by setting a rotating partition 3 in the partition cavity 101 to form multiple chambers, the amount of crops entering the mixing cavity 102 can be precisely controlled, improving sampling accuracy. During the feeding process, the crushing box 8 can continuously crush the newly added agricultural products, ensuring the continuity of material supply. At the same time, the processing box 1 can tilt during the discharge process. This design can achieve more thorough discharge, avoiding material residue from affecting the next sampling. After completing one sampling and discharge, the partition 3 continues to rotate, allowing the new chamber containing crushed crops to directly enter the mixing cavity 102, reducing the time required for re-crushing and significantly improving sampling efficiency. Overall, it optimizes the sampling process for pesticide residue detection of agricultural products, providing strong support for efficient and accurate detection work.
[0030] Please see Figure 1 and 3 Among them, two limiting rods 16 are fixedly connected to the processing box 1, and the limiting rods 16 are located at the bottom of the mounting base 12.
[0031] In this invention, when the processing box 1 tilts, the limiting rod 16 will also tilt accordingly. When the peak value is reached, it will limit the processing box 1 from continuing to tilt, thereby preventing excessive tilting and loss of stability.
[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
