Description

A detection device and method based on pesticide residue food

[0001] The present invention relates to a device and method for detecting pesticide residues in food, in particular to a device and method for detecting pesticide residues in food, and belongs to the technical field of sampling devices for detecting pesticide residues in food.

[0002] As people gradually understand the importance of a healthy diet to good health, more and more vegetables are being put on the table. However, vegetables need to be sprayed with pesticides during the planting process to prevent pests. Although this practice increases crop yields, it also causes people to eat vegetables containing a certain amount of pesticides. Therefore, vegetables need to be sampled and tested before they are put on the market for sale to ensure that the pesticide content in the vegetables meets the relevant national standards.

[0003] Existing rapid pesticide residue testing instruments are used for rapid testing of pesticide residues in vegetables and fruits by organizations such as agricultural law enforcement, industrial and commercial quality inspection, hotels and canteens, agricultural demonstration bases, green food production bases, and vegetable markets. They follow the national standard enzyme inhibition method, employing novel reagents, rapid color development, and room temperature incubation, allowing for on-machine testing. Validated by national and local governments, they boast a compliance rate exceeding 95%. Existing methods for testing pesticide residues in agricultural products primarily include biochemical assays and chromatographic methods.

[0004] However, existing sampling devices for food pesticide residue testing have the following drawbacks: 1. Existing pesticide testing devices can only test one type of fruit or vegetable for pesticides at a time, which takes a long time and is inconvenient to use; 2. Fruits and vegetables are cut only once for pesticide testing before coming into contact with the testing reagent, resulting in large chunks; 3. The size of the cut food cannot be adjusted according to demand; and a large amount of testing reagent is required to come into contact with the fruit or vegetable for testing, resulting in waste and inconvenience. Therefore, there is an urgent need to improve pesticide residue food testing devices to address the above-mentioned issues.

[0030] 2. The detection device and method for pesticide residues in food uses a servo motor to drive the screw to rotate, and the rotation of the screw drives the slide to move left and right, thereby adjusting the inclination angle of the connecting rod and adjusting the stamping amplitude of the push plate, so as to better cooperate with the cutting mechanism to cut the food.

[0031] 3. The detection device and method for pesticide residues in food uses a drive motor to drive the take-up wheel, which rotates to reel in the cutting rope, making the cutting rope tight, preventing the cutting rope from loosening over time and causing poor cutting effect.

[0032] 4. The detection device and method for pesticide residues in food, through the setting of the slide rod, slide rail and slider, enables the linear displacement of the adjustment plate, thereby stably adjusting the sliding seat and further stably adjusting the spacing of the cutting rope.

[0053] Example 1:

[0054] In this embodiment, as shown in Figure 2, the detection device body 1 includes a base 101, a display screen 102 fixedly mounted on the upper surface of the base 101, and several detection seats 104 disposed within the base 101 for placing food. A groove 103 is formed on the upper surface of the base 101, and several detection seats 104 are equidistantly and removably mounted on the inner bottom wall of the groove 103. A cover 105 is rotatably mounted between the left and right inner walls of the groove 103 for shielding. The cut food is placed into the detection seat 104, and a drop of detection agent is added and shaken to mix well. A contrast solution is simultaneously placed into the detection seat 104 on the other side. The cover 105 is then closed, and the display screen 102 is operated to perform food pesticide residue testing.

[0055] It should be noted that the cover 105 is a light shield. Several detection seats 104 are symmetrically arranged in two groups to better carry out food testing. The steps for food pesticide residue detection are as follows: first, representative vegetable samples are collected, and information such as the source, variety, and planting method of the samples are recorded. Then the sample is processed: the collected vegetable samples are cleaned, crushed, mixed, and other treatments are carried out for subsequent testing. Then the extraction is carried out: the processed vegetable samples are placed in the extraction liquid, and the pesticide residues are extracted by ultrasonic or oscillation methods. Purification: the extraction liquid is purified to remove impurities and concentrate the pesticide residues. Finally, the test is carried out: the purified extract is added to the vegetable pesticide residue detection equipment, and the test is carried out according to the operating instructions of the equipment. Result determination: According to the display results of the equipment, it is compared with the standard to determine whether the pesticide residues in the vegetables exceed the standard. Report issuance: a test report containing the test data and judgment results is issued.

[0056] The detection device body 1 belongs to conventional technology known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0057] Example 2:

[0058] In this embodiment, as shown in Figure 6, the material detecting and pushing device 2 includes a feed box 201, a shell 202 and a push plate 203 arranged inside the feed box 201, a connecting component hinged between the shell 202 and the push plate 203, a transmission structure 206 arranged above the feed box 201 and connected to the upper surface of the shell 202 and pushing the push plate 203, and an adjustment structure 207 arranged inside the shell 202 and adjusting the downward movement amplitude of the push plate 203; the connecting component consists of two hinged seats 205 and a connecting rod 204 hinged between the two hinged seats 205.

[0059] In this embodiment, the transmission structure 206 includes a rotating shaft 2062 installed on the top of the feed box 201 through a bearing 2065 and fixed to the upper surface of the shell 202, an intermittent motor 2061 fixedly installed on the upper surface of the feed box 201, and a transmission wheel 2063 fixedly installed at the output end of the intermittent motor 2061 and the top of the rotating shaft 2062. A belt 3064 is connected between the two transmission wheels 2063.

[0060] In this embodiment, the adjustment structure 207 includes a servo motor 2071 fixedly mounted on one side of the shell 202, a screw 2072 mounted on the output shaft of the servo motor 2071 through a coupling and extending to the interior of the shell 202, and a slide 2073 threadedly connected to the outside of the screw 2072 and slidably connected to the interior of the shell 202. The two articulated seats 205 are respectively fixedly mounted on the push plate 203 and the opposite side of the slide 2073.

[0061] When this embodiment is in use, the servo motor 2071 drives the screw 2072 to rotate, and the rotation of the screw 2072 drives the slide 2073 to move left and right, thereby adjusting the inclination angle of the connecting rod 204, and adjusting the stamping amplitude of the push plate 203, so as to better cooperate with the cutting mechanism 3 to cut the food. In addition, by adjusting the stamping amplitude of the push plate 203, food of different thicknesses and lengths can be cut, further improving the applicability of the device.

[0062] Among them, the upper surface of the push plate 203 is fixedly installed with a guide rod 208 extending to the outside of the feed box 201. Through the installation of the guide rod 208, the push plate 203 is guaranteed to move linearly up and down, and stable stamping is achieved.

[0063] The bottom of the housing 202 is provided with a sliding opening adapted for the slide 2073. The interior of the feed box 201 is provided with a feed port 2011 and a discharge port 209. The bottom end of the feed box 201 is mounted to the upper surface of the frame 301 via multiple sets of bolts. The end of the lead screw 2072, away from the servo motor 2071, is connected to a bearing on the inner wall of the housing 202.

[0064] It should be noted that an inclined drainage seat can be provided on the inner bottom wall of the shell 202 to facilitate the guidance of the food, and the push plate should be smaller than the discharge port 209 to better push the food.

[0065] Example 3:

[0066] In this embodiment, as shown in Figure 11, the cutting mechanism 3 includes a frame 301 arranged at the bottom end of the feed box 201, a plurality of cutting ropes 302 passed through the frame 301 and used to cut food, a plurality of wire structures 303 arranged outside the frame 301 and used to straighten the cutting ropes 302, a concave frame 304 fixedly installed on one side of the frame 301, and a spacing moving structure 305 arranged on the concave frame 304 and synchronously adjusting the plurality of wire structures 303; the spacing moving structure 305 includes a driving structure 3051 arranged on the concave frame 304, an adjusting plate 3052 slidably arranged on the concave frame 304 and connected to the driving structure 3051, a sliding rod 3053 fixedly installed on the inner wall of the opposite side of the concave frame 304 and passing through the interior of the wire structure 303, and a connecting member 3054 installed outside the wire structure 303 and slidably connected to the adjusting plate 3052. The drive structure 3051 includes a reduction motor 30511 fixedly mounted on the outside of the concave frame 304, a transmission screw 30512 rotatably mounted within the concave frame 304, two adjustment seats 30513 symmetrically threadedly connected to the outside of the transmission screw 30512, and two adjustment rods 30514 hinged between the two adjustment seats 30513 and the adjustment plate 3052. The drive motor 3034 drives the take-up wheel 3033, which rotates to reel in the cutting rope 302, keeping the cutting rope 302 taut and preventing the cutting rope 302 from loosening over time, which would result in poor cutting performance.

[0067] The wire structure 303 also adjusts the tightness of the cutting rope 302, preventing it from being too loose or too tight, which could lead to breakage. The threads on the drive screw 30512 are arranged in opposite directions, allowing the two adjustment seats 30513 to move relative to or towards each other. The concave frame 304 is equipped with a limiter that guides the two adjustment seats 30513, ensuring linear movement.

[0068] In this embodiment, the wire structure 303 includes a sliding seat 3031, a mounting bracket 3032 bolted to the upper surface of the sliding seat 3031, a take-up reel 3033 rotatably mounted on the inner bottom wall of the mounting bracket 3032 to reel and secure the cutting rope 302, and a drive motor 3034 fixedly mounted to the upper surface of the mounting bracket 3032 and secured to the top of the take-up reel 3033. A through hole 3058 is defined within the sliding seat 3031, and a slide rod 3053 extends through the interior of the sliding seat 3031 through the through hole 3058. The drive structure 3051 drives the adjustment plate 3052 to move forward and backward. The adjustment plate 3052 is moved forward and backward by the shaft 30542 and the oblique adjustment opening 3055, thereby synchronously adjusting the plurality of cutting ropes 302, thereby enabling food to be cut into a desired size as needed.

[0069] It should be noted that the frame 301 is fixed to the top of the collecting box 4 by bolts. The discharge port 209 is smaller than the frame 301.

[0070] In this embodiment, the connecting member 3054 includes a connecting block 30541 fixedly mounted on one side of the sliding seat 3031 close to the adjustment plate 3052, a shaft rod 30542 rotatably mounted on the upper surface of the other end of the connecting block 30541 and slidably connected to the inside of the adjustment plate 3052, an oblique adjustment opening 3055 adapted to the shaft rod 30542 is provided inside the adjustment plate 3052, and a sealing plate 306 for shielding is detachably mounted on the upper surface of the concave frame 304; the number of oblique adjustment openings 3055 and connecting members 3054 are adapted to the number of sliding seats 3031.

[0071] Among them, the number of spacing movable structures 305 is four, and the four spacing movable structures 305 are evenly distributed around the frame 301, and a number of wire structures 303 are evenly distributed in groups of five on the four spacing movable structures 305, and a number of cutting ropes 302 are arranged vertically and horizontally on the frame 301, and connecting openings 3011 are opened on all four sides of the frame 301.

[0072] In addition, the left and right two of the five oblique adjustment openings 3055 are symmetrically arranged, while the middle oblique adjustment opening 3055 is vertically arranged. The more outward the oblique adjustment opening 3055 is, the greater the inclination angle is, thereby enabling synchronous adjustment of the five guide structures 303.

[0073] In this embodiment, a guide assembly for limiting the adjustment plate 3052 is provided on the inner wall on the opposite side of the concave frame 304, and the guide assembly includes a slide rail 3056 fixedly installed on the inner wall of the concave frame 304 and a slider 3057 fixedly installed on the inner wall of one side of the adjustment plate 3052 and slidingly connected to the slide rail 3056; through the arrangement of the slide rod 3053, the slide rail 3056 and the slider 3057, the adjustment plate 3052 is linearly displaced, thereby stably adjusting the sliding seat 3031, and then stably adjusting the spacing of the cutting rope 302.

[0074] There are two reduction motors 30511, mounted opposite each other on the outside of the left and right concave frames 304. There are four drive screws 30512, equally spaced on the four concave frames 304. A worm 30515 is mounted on the separated ends of the left and right drive screws 30512, and the other ends of the left and right drive screws 30512 are fixed to the output shafts of the two reduction motors 30511. Worm wheels 30516, which mesh with the two worms 30515, are mounted on the right end of the front drive screw 30512 and the separated ends of the rear drive screw 30512.

[0075] In this embodiment, a collection box 401 that can extend outside the collection box is slidably installed inside the collection box 4, and sliding bars 402 connected to the inside of the collection box 4 are installed on the left and right outer walls of the collection box 401. A handle 403 is fixedly installed on the front of the collection box 401, and a controller 5 and a mounting platform 6 are fixedly installed on the right side of the collection box 4, and the base 101 is fixedly installed on the upper surface of the mounting platform 6.

[0076] Another technical problem to be solved by the present invention is to provide a method for detecting pesticide residues in food, comprising the following steps:

[0077] 1) List the foods to be tested for pesticides and arrange them in order;

[0078] 2) Food is introduced into the feed box 201 through the feed port 2011, and the intermittent motor 2061 is started. The transmission wheel 2063 and the belt 2064 drive the housing 202 to rotate. The rotation of the housing 202 drives the push plate 203 to move up and down through the connecting rod 204. The push plate 203 moves to squeeze the food downward and enter the cutting mechanism 3 through the discharge port 209;

[0079] 3) The cutting ropes 302 arranged vertically and horizontally cooperate with the pressure of the push plate 203 to cut the food into blocks. When the spacing of the cutting ropes 302 needs to be adjusted, the adjustment plate 3052 is driven forward and backward by the driving structure 3051. The adjustment plate 3052 is moved by the shaft 30542 and the oblique adjustment port 3055, thereby synchronously adjusting the cutting ropes 302, thereby cutting the food into the desired size according to the needs.

[0080] 4) The cut food falls into the collection box 4 and is collected by the collection box 401. The inspector removes the collection box 401 using the handle 403, places the cut food into the detection seat 104, drips the detection agent into it, and shakes it evenly. At the same time, the contrast solution is placed into the detection seat 104 on the other side. The cover 105 is then closed and the display screen 102 is operated to conduct the food pesticide residue test.

[0081] It should be noted that the food cut using this method is better in terms of detectability and applicability than the current food.

[0082] As shown in Figure 11, the principle of the book sorting and placing device provided in this embodiment is as follows: during testing, food is introduced into the feed box 201 through the feed port 2011, and the intermittent motor 2061 is started. The housing 202 is driven to rotate through the transmission wheel 2063 and the belt 2064. The rotation of the housing 202 drives the push plate 203 to move up and down through the connecting rod 204. The push plate 203 moves to squeeze the food downward and enters the cutting mechanism 3 through the discharge port 209. The food is cut by the cutting rope 302 arranged vertically and horizontally and the pressure of the push plate 203, so that the food is cut into blocks. The cut food falls into the collection box 4 and is collected by the collection box 401. The tester takes out the collection box 401 through the handle 403, puts the cut food into the test seat 104, drips the detection agent into it and shakes it evenly, and puts the contrast liquid into the test seat 104 on the other side. Then, the cover 105 is closed and the display screen 102 is operated to perform food pesticide residue detection.

[0083] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
