Description

Technical Field

[0001] The utility model relates to the technical field of pesticide detection, in particular to an imprint gel composite filtering component for pesticide detection. Background Technique

[0002] When detecting pesticides, it is necessary to use imprint gel. Through the capillary action of the imprint gel, the molecules in the gel are transferred to the outside of granular pesticides, so as to detect whether the pesticides are qualified. However, the cost of the imprint gel is relatively high, and the imprint gel outside the pesticides needs to be screened and filtered and collected again.

[0003] When the imprint gel is preliminarily filtered, the pesticides are poured into the inside of the sieve plate, and the surface layer of the pesticides is rubbed against the filter plate by shaking the sieve plate, so as to separate the pesticides and the imprint gel as much as possible, and then the mixture of the separated imprint gel and pesticides is further processed.

[0004] However, the weight of the pesticides is limited, the friction time between the pesticides and the filter plate is short, and the friction force is insufficient, which will cause part of the imprint gel not to be completely separated from the pesticides and result in waste of the imprint gel. Therefore, this application proposes an imprint gel composite filtering component for pesticide detection. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the background technique, the weight of the pesticides is limited, the friction time between the pesticides and the filter plate is short, and the friction force is insufficient, which will cause part of the imprint gel not to be completely separated from the pesticides and result in waste of the imprint gel, and to propose an imprint gel composite filtering component for pesticide detection.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a pesticide detection imprint gel composite filter assembly, including a filter plate 1, a protective ring 2 fixedly connected to the outside of the filter plate 1, a positioning frame 8 externally provided, and a support plate 9 fixedly connected to the outside of the positioning frame 8. There are two sets of support plates 9 arranged symmetrically, which can support the positioning frame 8. A base 10 is fixedly connected to the bottom of the support plate 9, which can continue to collect the screened imprint gel. A squeezing plate 3 abuts against the top of the filter plate 1. A motor 4 is provided on the top of the squeezing plate 3 away from the filter plate 1. The output end of the motor 4 is fixedly connected to the squeezing plate 3 at a position away from the center. The motor 4 can drive the squeezing plate 3 to make a circular motion on one side of the filter plate 1, thereby increasing the contact force and contact area between the pesticide and the filter plate 1 at different positions. A pressing component is provided above the motor 4.

[0024] also Figure 1 , Figure 2 As shown, the pressing assembly includes a hydraulic rod 5. The output end of the hydraulic rod 5 is fixedly connected to the side of the motor 4 away from the extrusion plate 3. The hydraulic rod 5 can push the motor 4 and the extrusion plate 3 to press down on the pesticide, so that the pesticide surface has sufficient pressure to contact the filter plate 1, thereby screening out as much of the pesticide surface marking gel as possible. The positioning frame 8 and the support plate 9 are fixedly connected to the top of the support frame 7. The hydraulic rod 5 is fixedly connected inside the support frame 7. The support frame 7 supports the hydraulic rod 5 to make the extension and retraction more stable. The support frame 7 is arranged in a "U" shape. The top of the support frame 7 is fixedly connected to the hydraulic oil tank 6. The hydraulic oil tank 6 stores hydraulic oil to provide power for the extension and retraction of the hydraulic rod 5. The hydraulic oil tank 6 and the hydraulic rod 5 are connected.

[0025] in addition Figure 2 , Figure 3As shown, a connecting ring 11 is fixedly connected to the outside of the motor 4, and a push rod 12 is fixedly connected to the outside of the connecting ring 11. The push rod 12 is arranged in an inverted "L" shape. The position of the push rod 12 can be fixed by the connecting ring 11. There are two sets of push rods 12 arranged symmetrically. A sliding pad 13 is fixedly connected to the end of the push rod 12 away from the connecting ring 11. The sliding pad 13 can distribute the pressure to most of the extrusion plate 3 positions on the top of the extrusion plate 3, which evens out the pressure of the extrusion plate 3 and improves the separation effect of the imprint gel and pesticide. The sliding pad 13 abuts against the side of the extrusion plate 3 near the motor 4.

[0026] In this embodiment, the pesticide with the attached imprint gel is first spread on the surface of the filter plate 1. The extension length of the hydraulic rod 5 is adjusted by the hydraulic oil tank 6 supported by the support plate 9 and the positioning frame 8. Then, the motor 4 is started, so that the motor 4 drives the extrusion plate 3 to extrude and spread the pesticide above the filter plate 1, thereby increasing the contact between the pesticide at various positions above the filter plate 1 and the surface of the filter plate 1, thereby separating the imprint gel on the surface of the pesticide.

[0027] When the extrusion plate 3 spreads and extrudes the pesticide, the position of the connecting ring 11 outside the motor 4 is adjusted so that the position of the connecting ring 11 relative to the push rod 12 is fixed. When the extrusion plate 3 rotates, the top of the extrusion plate 3 slides along the bottom of the sliding pad 13 so that the downward pressure at each position of the extrusion plate 3 is consistent when it rotates.

[0028] The mixture of pesticides and imprint gels separated by sieving falls onto the surface of the base 10 for unified collection and processing, while the pesticides that have been sieved remain on the top of the filter plate 1, where they can be collected again for further separation processing.

[0029] It should be noted that this device uses an eccentric connection between the motor 4 and the extrusion plate 3, which allows the pesticides on various positions on the surface of the filter plate 1 to be evenly spread. Furthermore, the hydraulic rod 5 can control the pressure of the extrusion plate 3 on the pesticides, avoiding the problem of poor separation between pesticides and imprint gels due to the limited weight of the pesticides themselves, thus improving the screening and filtration effect of imprint gels and pesticides.

[0030] Example 2

[0031] like Figure 2 and Figure 4As shown, based on Embodiment 1, a spring 14 is fixedly connected to the outside of the protective ring 2. There are four springs 14 arranged in a circumferential array. The springs 14 allow the filter plate 1 and the protective ring 2 to shake in conjunction with the extrusion plate 3. A sliding component is provided at the end of the spring 14 away from the protective ring 2. The sliding component includes a sliding block 15, which is fixedly connected to the end of the spring 14 away from the protective ring 2. The sliding block 15 is slidably connected to the inside of the positioning frame 8. The sliding block 15 can adjust the shaking protective ring 2 by sliding inside the positioning frame 8. A telescopic rod 17 is fixedly connected to the opposite side of the sliding block 15 and the protective ring 2. The telescopic rod 17 can assist the spring 14 in telescopic movement. A slide rail 16 is slidably connected to the outside of the positioning frame 8. There are two sets of slide rails 16 arranged symmetrically. The slide rail 16 can limit the sliding position of the sliding block 15. The slide rail 16 is fixedly connected to the inside of the positioning frame 8.

[0032] In this embodiment, when the extrusion plate 3 rotates, it will impact the inner wall of the protective ring 2. At this time, the protective ring 2 will shake, thereby squeezing the spring 14. The spring 14 will also shake with the shaking of the protective ring 2. In order to improve the buffering force of the spring 14 on the protective ring 2, the sliding block 15 is allowed to slide inside the positioning frame 8, which can cooperate with the shaking of the protective ring 2. The extension and retraction of the spring 14 is limited by the telescopic rod 17 to prevent the spring 14 from deflecting and bending during extension and retraction.

[0033] Furthermore, when the spring 14 drives the sliding block 15 to slide, the telescopic rod 17 can also transmit the sliding force to the sliding block 15, thus preventing the stress at the connection between the spring 14 and the sliding block 15 from being too great and breaking. When the sliding block 15 slides, its sliding direction is restricted by the slide rail 16, and the sliding block 15, in conjunction with the telescopic rod 17 inside the slide rail 16, can also provide support for the protective ring 2.

[0034] It should also be noted that the telescopic structure of the spring 14 and the telescopic rod 17 in this device allows the protective ring 2 to shake when the extrusion plate 3 rotates, avoiding the problem of damage caused by friction between the edge of the extrusion plate 3 and the inner wall of the protective ring 2, thereby improving the impact resistance of the protective ring 2 and the screening and filtering effect of the filter plate 1.

[0035] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
