Description

Technical Field

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

[0002] In food pesticide testing, sampling is often used. The sampling bottle is brought into the workshop, the sample is placed in the bottle, and then the bottle is manually shaken to thoroughly mix the sample and the washing solution. The washing solution washes away the pesticides on the sample surface, resulting in a mixed pesticide washing solution. This washing solution is then brought back to the laboratory for testing. However, in this testing process, the tester's arm cannot maintain stable shaking for an extended period, which may result in pesticide residue remaining on the sample surface, leading to inaccurate test data. Furthermore, during shaking, the sample may shake along with the washing solution, preventing the washing solution from completely washing away the pesticides on its surface. Utility Model Content

[0016] The beneficial effects of this swaying mechanism are as follows: the drive component drives the lifting plate to reciprocate, and the movement trajectory of the lifting plate is restricted by the limiting component, so that the lifting plate can only reciprocate in the vertical direction. The mechanical swaying method solves the problem that the human body cannot perform stable and efficient swaying for a long time when sampling in the workshop.

[0019] The clamping unit includes a fixed clamping plate disposed inside the sealing cover, a rotating clamping plate rotatably disposed on the fixed clamping plate, and a fixing assembly disposed at the same end of the fixed clamping plate and the rotating clamping plate;

[0020] The fixed clamping plate and the rotating clamping plate are rotatably connected by a rotating assembly, and the housing is fixed to one side of the connecting plate by the connecting assembly.

[0021] As a preferred embodiment of the pesticide residue detection device of this utility model, the pressurizing component includes threaded rods disposed on both sides of the housing, connecting ears disposed on both sides of the sealing cover, and a connecting cap threaded to the top of the threaded rod.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] Example 1

[0038] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a shaking mechanism, including a mounting unit 100, including a mounting plate 101 and a mounting bracket 102 disposed above the mounting plate 101;

[0039] The lifting unit 200 includes a lifting plate 201 slidably disposed on the top of the mounting frame 102, a limiting component 202 disposed between the mounting frame 102 and the lifting plate 201, and a driving component 203 disposed between the mounting frame 102 and the lifting plate 201.

[0040] The connecting unit 300 includes a connecting plate 301 disposed on one side of the lifting plate 201, and a connecting component 302 disposed on one side of the connecting plate 301.

[0041] It should be noted that the mounting unit 100 includes a mounting plate 101, and a mounting bracket 102 is fixedly connected to the upper surface of the mounting plate 101.

[0042] The lifting unit 200 includes a lifting plate 201 that passes through the top of the mounting frame 102 and is slidably connected to the mounting frame 102. A limit component 202 is provided between the lifting plate 201 and the mounting frame 102. The limit component 202 can limit the movement trajectory of the lifting plate 201. A drive component 203 is fixedly connected to the mounting frame 102. The output end of the drive component 203 is connected to the lifting plate 201 and can drive the lifting plate 201 to reciprocate.

[0043] In use, the sample bottle is connected to one side of the connecting plate 301 via the connecting component 302. After the sample bottle is fixed, the drive component 203 is started. The drive component 203 drives the lifting plate 201 to perform rapid reciprocating motion. At the same time, the limiting component 202 ensures that the connecting plate 301 performs reciprocating motion in the vertical direction. After the sample and washing solution in the sample bottle are mixed by shaking, the residual pesticides on the sample will be washed away and mixed by the washing solution. The pesticide residues can be detected by testing the washing solution.

[0044] In summary, by shaking the sample and the washing solution in the sample bottle, the residual pesticides on the sample will be washed away by the washing solution during the shaking process. Then, by detecting pesticides in the washing solution, the amount of residual pesticides in the sample can be determined.

[0045] Example 2

[0046] Reference Figures 1-6 In a second embodiment of the present invention, the limiting component 202 is further provided, including a limiting groove 202a formed on the side of the lifting plate 201, and a limiting member 202b disposed in the limiting groove 202a;

[0047] One side of the limiting member 202b is fixedly connected to the mounting bracket 102.

[0048] Furthermore, the drive assembly 203 includes a motor 203a mounted on one side of the mounting bracket 102, a rotating disk 203b rotatably mounted on the top of the mounting bracket 102, a rotating rod 203c rotatably mounted on one side of the rotating disk 203b, and a transmission component 203d mounted on the output end of the motor 203a and the rotating disk 203b.

[0049] One end of the rotating rod 203c is rotatably connected to the lifting plate 201.

[0050] Furthermore, the connecting assembly 302 includes bolts 302a fixedly connected to the inflection points of the connecting plate 301, and nuts 302b threaded onto the outer wall of the bolts 302a.

[0051] Furthermore, the limiting member 202b includes a fixed seat 202b-1 disposed in the inner cavity of the mounting bracket 102, a limiting post 202b-2 disposed on one side of the fixed seat 202b-1, and a limiting piece 202b-3 disposed at one end of the limiting post 202b-2;

[0052] Limiting post 202b-2 penetrates limiting groove 202a

[0053] Furthermore, the transmission component 203d includes a transmission wheel 203d-1 disposed at the output end of the motor 203a, a driven wheel 203d-2 disposed on the rotating shaft of the rotating disk 203b, and a transmission belt 203d-3 disposed on the driven wheel 203d-2 and the transmission wheel 203d-1.

[0054] It should be noted that the drive assembly 203 includes a limiting groove 202a vertically opened on the lifting plate 201, and a limiting member 202b slidably connected in the limiting groove 202a. The limiting member 202b includes a fixed seat 202b-1 fixedly installed in the inner cavity of the mounting bracket 102. A limiting post 202b-2 is fixedly connected to one outer wall of the fixed seat 202b-1. The limiting post 202b-2 passes through the limiting groove 202a, and a limiting piece 202b-3 is fixedly connected to the same end of the limiting post 202b-2.

[0055] The drive assembly 203 includes a motor 203a mounted on the outer wall of one side of the mounting bracket 102, a rotating disk 203b rotatably connected to the top of the mounting bracket 102, a rotating rod 203c rotatably connected to the rotating disk 203b, the other end of the rotating rod 203c being rotatably connected to the lifting plate 201, and the mounting point of the rotating rod 203c on the rotating disk 203b being any point other than the center of the rotating disk 203b.

[0056] In use, by starting the motor 203a, the motor 203a drives the transmission wheel 203d-1 to rotate. The transmission wheel 203d-1 drives the driven wheel 203d-2 to rotate through the transmission belt 203d-3. When the driven wheel 203d-2 drives the rotating disk 203b to rotate, it will drive the rotating rod 203c to push the lifting plate 201 up and down. Under the action of the limiting groove 202a and the limiting member 202b, the lifting plate 201 can only move in the vertical direction, thereby driving the connecting plate 301 to reciprocate in the vertical direction.

[0057] In summary, the motor 203a drives the rotating disk 203b to rotate, thereby pushing and pulling the lifting plate 201 to move. The lifting plate 201 can only produce vertical displacement by setting the limiting groove 202a and the limiting member 202b, thus realizing the vertical reciprocating motion, thereby driving the connecting plate 301 to reciprocate.

[0058] Example 3

[0059] Reference Figures 1 to 7 This is the third embodiment based on the second embodiment of the present utility model. Unlike the second embodiment, the drive assembly 203 includes a second motor disposed on one side of the mounting bracket 102, a pressing rod disposed on the output end of the second motor, a horizontal frame disposed on one side of the lifting plate 201, and a spring disposed below the horizontal frame.

[0060] It should be noted that the drive assembly 203 includes a second motor fixedly installed on one side of the mounting bracket 102, a pressing rod fixedly connected to the output end of the second motor, a horizontal frame fixedly connected to one side of the bottom end of the lifting plate 201, the pressing rod being located above the horizontal frame, and a spring being provided below the horizontal frame.

[0061] In use, the second motor rotates, driving the pressing rod to rotate. One end of the pressing rod will contact the horizontal frame, and during the rotation, it will press the horizontal frame to the bottom of the pressing rod. Then the pressing rod separates from the horizontal frame, and the horizontal frame returns to its original position under the action of the spring. Then the pressing rod presses the horizontal frame again, and the operation is repeated to realize the reciprocating motion of the horizontal frame driving the lifting plate 201.

[0062] In summary, unlike Embodiment 2, this structure is simpler, but when the pressing rod is working, a swing space needs to be reserved on the right side of the pressing rod. Compared with Embodiment 2, the required operating space is larger. Therefore, the driving component 203 of Embodiment 2 is more applicable.

[0063] Example 4

[0064] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a pesticide residue detection device, including a sampling unit 400, which includes a housing 401, a sealing cover 402 disposed above the housing 401, and a pressure assembly 403 disposed between the housing 401 and the sealing cover 402.

[0065] The clamping unit 500 includes a fixed clamping plate 501 disposed inside the sealing cover 402, a rotating clamping plate 502 rotatably disposed on the fixed clamping plate 501, and a fixing component 503 disposed at the same end of the fixed clamping plate 501 and the rotating clamping plate 502.

[0066] The fixed clamping plate 501 and the rotating clamping plate 502 are rotatably connected by the rotating assembly 504, and the housing 401 is fixed to one side of the connecting plate 301 by the connecting assembly 302.

[0067] It should be noted that the sampling unit 400 includes a housing 401, and the housing 401 and the sealing cover 402 form a sealed cavity inside the housing 401 through the pressurization assembly 403;

[0068] The clamping unit 500 includes a fixed clamping plate 501 fixedly installed inside the sealing cover 402. A rotating clamping plate 502 is rotatably connected to the fixed clamping plate 501 via a rotating assembly 504. A fixing assembly 503 is provided at the same end of the rotating clamping plate 502 and the fixed clamping plate 501 to fix the fixed clamping plate 501 and the rotating clamping plate 502.

[0069] Furthermore, the pressurization assembly 403 includes threaded rods 403a disposed on both sides of the housing 401, connecting lugs 403b disposed on both sides of the sealing cover 402, and connecting caps 403c threaded onto the top of the threaded rods 403a.

[0070] It should be noted that the pressurizing component 403 includes threaded rods 403a fixedly installed on both sides of the housing 401, and connecting ears 403b fixedly connected to both sides of the sealing cover 402. The connecting ears 403b are passed through the threaded rods 403a and the connecting caps 403c are tightened to achieve a sealed connection.

[0072] It should be noted that by joining the two fixing caps 503a together and then looping the elastic rope 503b over the fixing caps 503a, the fixing plate 501 and the rotating plate 502 are closed and fixed.

[0073] Furthermore, the rotating assembly 504 includes a rotating seat 504a disposed on the fixed clamping plate 501, and positioning rods 504b disposed on both sides of the rotating clamping plate 502;

[0074] Positioning rod 504b is rotatably connected within rotating seat 504a.

[0075] It should be noted that positioning rods 504b are fixedly connected to the outer walls on both sides of the rotating clamp 502. The positioning rods 504b rotate within the rotating seat 504a set on the fixed clamp 501, thereby realizing the rotational connection between the fixed clamp 501 and the rotating clamp 502.

[0076] In use, open the rotating clamp 502, place the test sample between the rotating clamp 502 and the fixed clamp 501, close the rotating clamp 502, and then put the elastic rope 503b on the fixed cap 503a to fix the test sample. Inject the washing solution into the housing 401, then insert the clamping unit 500 into the housing 401, close the housing 401 through the pressure assembly 403, and then fix the housing 401 to the connecting plate 301 through the connecting assembly 300. Start the shaking mechanism to shake the housing 401. After the sample and washing solution in the housing 401 are mixed by shaking, the residual pesticides on the sample will be washed away by the washing solution. By testing the washing solution, the pesticide residues can be detected.

[0077] In summary, the sample is clamped and fixed by the clamping unit 500. When the shaking mechanism drives the housing 401 to shake, the washing solution will repeatedly wash the sample surface to remove the pesticide residue. Then the washing solution is mixed and tested to detect the pesticide product.
