Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection technology, and in particular to a pesticide residue detection device. Background Technology

[0002] Pesticides, as an indispensable part of modern agricultural production, play a vital role in increasing crop yields and controlling pests and diseases. However, the widespread use of pesticides has also led to pesticide residue problems, posing a potential threat to human health. To ensure the safety of agricultural products, pesticide residue testing has become a key link in food safety supervision. Currently, pesticide residue testing typically involves examining the juice of crops.

[0003] In the existing pesticide residue detection device, the stirring rod is directly rotatably connected to the cover plate, while the cover plate is fixedly connected to the electric telescopic rod, which is connected to the base. The stirring rod cannot be disassembled separately. During cleaning, the stirring rod is still above the test tube tank, which makes it easy for cleaning solution to fall into the test tube tank, which is very inconvenient.

[0004] An existing patent (publication number: CN218350247U) describes a pesticide residue detection device. When cleaning the stirring rod, the threaded sleeve is rotated, causing it to gradually move downwards and separate from the transmission rod. This removes the threaded sleeve from the stirring rod, allowing it to slide downwards and disengage the limiting rod from the transmission rod. This further separates the stirring rod from the transmission rod, enabling it to be detached for separate cleaning. The device prevents cleaning solution from falling into the test tube tank during cleaning, making it very convenient.

[0005] Existing patents offer solutions to the above problems, but they cannot crush or squeeze crops for juicing. This means that the detection process requires external equipment to extract the juice before pesticide residue detection can be performed, which reduces the efficiency of pesticide residue detection.

[0006] Therefore, a pesticide residue detection device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a pesticide residue detection device that can solve the problem that existing pesticide residue detection devices cannot crush and squeeze crops for juice extraction, which leads to a decrease in the efficiency of pesticide residue detection.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pesticide residue detection device, including a detection platform, two placement cylinders are arranged on one side of the detection platform, a detection measuring cup is arranged inside the placement cylinder, a squeezing and crushing mechanism is arranged on the top of the detection platform, and a limiting filter mechanism is arranged on the top of the placement cylinder.

[0009] The crushing and extrusion mechanism includes a support frame fixedly connected to the top of the testing platform. A lifting plate is provided on the side wall of the support frame. An electric push rod is bolted to the top of the support frame. The output end of the electric push rod is fixedly connected to the lifting plate. Two crushing shafts are connected to the two sides of the lifting plate by bearings. A crushing disc is provided at the bottom of the crushing shaft. Crushing teeth are provided on the bottom surface of the crushing disc. A drive assembly is provided at the top of the lifting plate.

[0010] Preferably, the drive assembly includes a drive motor bolted to the bottom of the lifting plate, a drive wheel fixedly connected to the output end of the drive motor, a driven wheel fixedly connected to the top of the crushing shaft, and a transmission belt provided between the drive wheel and the driven wheel.

[0011] Preferably, the limiting filter mechanism includes a support base fixedly connected to the top of the placement cylinder, a filter cylinder fixedly connected to the top of the support base, a filter groove provided on the side wall of the filter cylinder, a filter screen fixedly connected to the inner wall of the filter cylinder, a plurality of limiting heads fixedly connected to the side wall of the filter cylinder, and a plurality of limiting grooves opened on the top of the support base, with the limiting heads movably connected to the limiting grooves.

[0012] Preferably, a plurality of guide cylinders are fixedly connected to the bottom surface of the lifting plate, and guide rods are movably arranged inside the guide cylinders. A pressing plate is provided at the bottom of two of the guide rods, and the bottom surface of the pressing plate is in contact with the filter cylinder.

[0013] Preferably, a rubber ring is fixedly connected to the bottom surface of the filter cylinder, and the bottom surface of the rubber ring is in contact with the measuring cup.

[0014] Preferably, a support pad is provided at the bottom of the placement cylinder, and the top of the support pad is in contact with the measuring cup.

[0015] Preferably, two sliding frames are fixedly connected to the side wall of the support frame, and two sliders are fixedly connected to the side wall of the lifting plate, with the sliders movably disposed inside the sliding frames.

[0016] Preferably, a disinfection cabinet is provided on one side of the testing station, and the disinfection cabinet is used to store the measuring cups and filter cylinders.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates a crushing and grinding mechanism, which enables the sample to be crushed quickly and evenly, thereby effectively releasing pesticide residues. This avoids the problems of uneven sample processing or low efficiency in traditional methods, improving the efficiency of detection. Specifically, during use, the electric push rod drives the lifting plate to move downwards, and the drive assembly drives the crushing shaft to rotate. During this process, the crushing disc rotates, crushes, and pressurizes the crops, allowing the crops to be quickly juiced.

[0019] 2. This application incorporates a limiting filtration mechanism. This process utilizes a filter cylinder and a filter screen to effectively filter out solid residues in the sample, ensuring the accuracy of the test results. Simultaneously, the detachable design of the filter cylinder facilitates cleaning and maintenance. Specifically, a filter screen is installed on the inner wall of the filter cylinder, and the cooperation of the limiting head and limiting groove allows the filter cylinder to be fixed at the top of the placement cylinder, preventing loosening during filtration. Through the filter screen and filter groove, the juice from the squeezed crop is filtered, ensuring the accuracy of the testing process. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution:

[0031] A pesticide residue detection device includes a detection platform 1, two placement cylinders 2 are arranged on one side of the detection platform 1, a detection measuring cup 3 is arranged inside the placement cylinder 2, a crushing and grinding mechanism 4 is arranged on the top of the detection platform 1, and a limiting filter mechanism 5 is arranged on the top of the placement cylinder 2.

[0032] The crushing mechanism 4 includes a support frame 41 fixedly connected to the top of the testing table 1. A lifting plate 42 is provided on the side wall of the support frame 41. An electric push rod 43 is bolted to the top of the support frame 41. The output end of the electric push rod 43 is fixedly connected to the lifting plate 42. Two crushing shafts 44 are connected to the two sides of the lifting plate 42 by bearings. A crushing disc 45 is provided at the bottom of the crushing shaft 44. Crushing teeth 46 are provided on the bottom surface of the crushing disc 45. A drive assembly 47 is provided at the top of the lifting plate 42.

[0033] Specifically, such as Figure 3 and Figure 5 As shown, the drive assembly 47 includes a drive motor 471 bolted to the bottom of the lifting plate 42, a drive wheel 472 fixedly connected to the output end of the drive motor 471, a driven wheel 473 fixedly connected to the top of the crushing shaft 44, and a transmission belt 474 provided between the drive wheel 472 and the driven wheel 473.

[0034] Specifically, such as Figure 4As shown, multiple guide cylinders 7 are fixedly connected to the bottom surface of the lifting plate 42. Guide rods 8 are movably arranged inside the guide cylinders 7. Pressing plates 9 are arranged at the bottom of the two guide rods 8. The bottom surface of the pressing plates 9 is in contact with the filter cylinder 52.

[0035] Specifically, such as Figure 4 As shown, two sliding frames 12 are fixedly connected to the side wall of the support frame 41, and two sliders 13 are fixedly connected to the side wall of the lifting plate 42. The sliders 13 are movably disposed inside the sliding frames 12.

[0036] During operation, the agricultural product sample to be tested is first placed into the testing measuring cup 3, and then the testing measuring cup 3 is placed inside the placement cylinder 2. Next, the electric push rod 43 is activated. The output end of the electric push rod 43 pushes the lifting plate 42 and its connected components to descend. During the descent, the lifting plate 42 moves smoothly and vertically through the cooperation of the slider 13 on its side wall and the sliding frame 12 on the side wall of the support frame 41. As the lifting plate 42 descends, the crushing shaft 44 and its bottom crushing disc 45 gradually approach and contact the sample inside the testing measuring cup 3. At this point, the drive motor 471 is activated, driving the electric... The output end of the machine 471 drives the drive wheel 472 to rotate, and transmits the power to the driven wheel 473 through the transmission belt 474, which in turn drives the crushing shaft 44 to rotate. During the rotation, the crushing teeth 46 on the crushing disc 45 perform efficient crushing of the sample. At the same time, the guide cylinder 7 and its internal guide rod 8, which are fixedly connected to the bottom surface of the lifting plate 42, and the pressing disc 9 at the bottom together form a stable pressing mechanism. During the descent of the lifting plate 42, the pressing disc 9 gradually presses the filter cylinder 52, ensuring that the crushed sample can smoothly enter the filter cylinder 52 for filtration.

[0037] Specifically, such as Figure 4 and Figure 6 As shown, the limiting filter mechanism 5 includes a support base 51 fixedly connected to the top of the placement cylinder 2, a filter cylinder 52 fixedly connected to the top of the support base 51, a filter groove 53 provided on the side wall of the filter cylinder 52, a filter screen 54 fixedly connected to the inner wall of the filter cylinder 52, a plurality of limiting heads 55 fixedly connected to the side wall of the filter cylinder 52, and a plurality of limiting grooves 56 opened on the top of the support base 51, with the limiting heads 55 movably connected to the limiting grooves 56.

[0038] Specifically, such as Figure 4 As shown, a rubber ring 10 is fixedly connected to the bottom surface of the filter cylinder 52, and the bottom surface of the rubber ring 10 is in contact with the measuring cup 3.

[0039] Specifically, such as Figure 4 As shown, a support pad 11 is provided at the bottom of the placement cylinder 2, and the top of the support pad 11 is in contact with the measuring cup 3.

[0040] Specifically, such as Figure 1 As shown, a disinfection cabinet 14 is provided on one side of the testing station 1. The disinfection cabinet 14 is used to store the testing measuring cup 3 and the filter cylinder 52.

[0041] During operation, the crushing mechanism crushes the agricultural product sample, which then falls into the measuring cup 3 inside the placement cylinder 2. The filter cylinder 52 is movably connected to the limiting groove 56 on the top of the support base 51 via the limiting head 55 on its side wall. This not only ensures the stable installation of the filter cylinder 52 but also allows users to easily disassemble and replace the filter cylinder 52 as needed. When the crushed sample enters the filter cylinder 52 through the measuring cup 3, the filter screen 54 effectively filters out solid residues in the sample, retaining only the liquid portion for subsequent testing. The filtered liquid enters the measuring cup 3. At the same time, the rubber ring 10 fixedly connected to the bottom surface of the filter cylinder 52 is in close contact with the measuring cup 3, achieving compression of the measuring cup 3. The bottom of the placement cylinder 2 is also provided with a support pad 11, which provides additional support and stability for the measuring cup 3, ensuring the stability of the sample during the crushing and filtering process. After the test, the user can put the used measuring cup 3 and filter cylinder 52 into the disinfection cabinet 14 for disinfection to ensure the accuracy and safety of the next test.

[0042] By adopting the above technical solution, the problem that existing pesticide residue detection devices cannot crush and squeeze crops for juice extraction, which leads to a decrease in the efficiency of pesticide residue detection, has been solved.

[0043] Working principle: In use, the agricultural product sample to be tested is first placed in the testing measuring cup 3, and then the testing measuring cup 3 is placed in the placement cylinder 2. Next, the filter cylinder 52 is placed in the support base 51. Then, the electric push rod 43 is activated. The output end of the electric push rod 43 pushes the lifting plate 42 and its connected components to descend. During the descent, the lifting plate 42 moves smoothly and vertically through the cooperation of the slider 13 on its side wall and the sliding frame 12 on the side wall of the support frame 41. As the lifting plate 42 descends, the crushing shaft 44 and its bottom crushing disc 45 gradually connect... When the sample is brought close to the test cup 3, the drive motor 471 is started. The output of the drive motor 471 drives the drive wheel 472 to rotate. The power is transmitted to the driven wheel 473 through the transmission belt 474, which in turn drives the crushing shaft 44 to rotate. During the rotation, the crushing teeth 46 on the crushing disc 45 efficiently crush the sample. When the crushed sample enters the filter cylinder 52 through the test cup 3, the filter screen 54 can effectively filter out the solid residue in the sample, retaining only the liquid part for subsequent testing. The filtered liquid enters the test cup 3.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
