Description
Technical Field
[0001] This utility model relates to the technical field of titration devices, and in particular to a washing solution titration device for detecting pesticide residues in agricultural products. Background Technology
[0002] In recent years, food and agricultural product testing pretreatment equipment has been developing towards specialization, speed, and automation. This field involves the integration of multiple disciplines such as chemistry, food, agriculture, industrial design, and intelligent manufacturing. Compared with other industries, the automation level of pesticide and veterinary drug residue testing pretreatment equipment at home and abroad is still relatively low.
[0003] In particular, when adding washing solution using the titration apparatus in testing equipment, it is difficult to adjust the burette needle to a suitable position relative to the test tube. If the burette needle is too far from the test tube, the washing solution may not be accurately dispensed; if the needle is inserted into the test tube, it may be contaminated by splashed solution, or it may directly enter the solution and contaminate it. All of these situations will affect subsequent experimental results; therefore, it is necessary to adjust the burette to a suitable position for titration. Summary of the Invention

[0014] The beneficial effects of this utility model are as follows: This utility model provides a washing solution titration device for detecting pesticide residues in agricultural products. By setting a translation component, the titration component can be moved horizontally, and by setting a lifting component, the titration component can be driven to rise and fall. Through the cooperation of various components in the titration component, the burette can reach the appropriate position to drip liquid into the test tube. Specifically, the cylinder drives the moving block to descend until the blocking block reaches the position of the first positioner. At this point, the positioner will contact the test tube.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0020] In one embodiment, such as Figure 1 As shown, a washing solution titration device 10 for detecting pesticide residues in agricultural products includes: a translation component 100, a lifting component 200, and a titration component 300; the lifting component 200 is slidably disposed on the translation component 100, and the translation component 100 is used to drive the lifting component 200 to translate on a horizontal plane; the titration component 300 is slidably disposed on the lifting component 200, and the lifting component 200 is used to drive the titration component 300 to perform lifting and lowering movements; the titration component 300 includes a movable plate 310, a first positioner 320, a second positioner 330, a cylinder 340, a moving block 350, a titration needle 360, and a positioning block 370; The movable plate 310 is slidably disposed on the lifting assembly 200. The first positioner 320 and the second positioner 330 are fixedly disposed on the movable plate 310, one above the other, and the first positioner 320 and the second positioner 330 are located on the same vertical line. The cylinder 340 is disposed on the movable plate 310 and is used to drive the moving block 350 to slide on the movable plate 310. The dosing needle 360 and the positioning block 370 are both disposed on the moving block 350. The moving block 350 is provided with a blocking block 351, which is used to pass through the first positioner 320 and the second positioner 330.
[0021] Specifically, the translation component 100 enables the titration component 300 to translate horizontally, and the lifting component 200 enables the titration component 300 to be lifted. Through the coordinated operation of the various components in the titration component 300, the burette 360 can reach the appropriate position to dispense liquid into the test tube. Further, the cylinder 340 drives the moving block 350 to descend until the blocking block 351 reaches the position of the first positioner 320. At this point, the positioning block 370 will contact the test tube. If the positioning block 370 does not contact the test tube, the test tube's position needs to be readjusted. Simultaneously, the burette 360 will draw up the washing liquid, preparing for subsequent dispensing into the test tube. Then, the cylinder 340 drives the moving block 350 to rise until the blocking block 351 reaches the position of the second positioner 330. Then, it drives the burette 360 above the test tube. At this point, the height of the burette 360 relative to the test tube is the most suitable titration height, allowing the washing solution to be accurately dripped into the test tube. The washing solution titration device 10 for pesticide residue detection in agricultural products provided in this application can accurately drip the washing solution into the test tube by adjusting the appropriate titration height of the burette 360, avoiding contamination of the burette 360 or the solution in the test tube.
[0022] In this embodiment, by linking the first positioner 320 and the second positioner 330 with the cylinder 340, the deviation range of the burette 360 can be less than 0.5 mm. Simultaneously, by adjusting the burette 360 to a suitable titration height, contact between the burette 360 and the solution can be effectively avoided, thereby effectively reducing experimental errors by 50%, demonstrating excellent technical effectiveness.
[0023] To allow the movable block 350 to slide more smoothly on the movable plate 310, in one embodiment, the movable plate 310 is provided with a groove 311, and the movable block 350 has a protruding sliding rod structure 352, which is slidably disposed within the groove 311. Specifically, when the cylinder 340 drives the movable block 350 to rise, the sliding rod will slide into the groove 311; when the cylinder 340 drives the movable block 350 to fall, the sliding rod will slide out of the groove 311. This arrangement allows the movable block 350 to slide more smoothly on the movable plate 310, preventing positional shifts during sliding.
[0024] To better achieve the positioning function, in one embodiment, the first locator 320 and the second locator 330 are infrared locators. Specifically, both the first locator 320 and the second locator 330 can emit and receive infrared signals. When the blocking block 351 reaches the first locator 320 or the second locator 330, the blocking block 351 will block the infrared signal, preventing the receiver from receiving it. Therefore, it can be determined that the blocking block 351 has reached the first locator 320 or the second locator 330, thereby achieving the positioning function.
[0025] In order to allow the titration component 300 to move more effectively on a horizontal plane, in one embodiment, such as Figure 1 As shown, the translation component 100 includes a first track rod 110, a second track rod 120, a third track rod 130, a first motor 140, and a second motor 150. The first track rod 110 and the second track rod 120 are arranged in parallel. One end of the third track rod 130 is slidably disposed on the first track rod 110, and the other end of the third track rod 130 is slidably disposed on the second track rod 120. The third track rod 130 is perpendicular to both the first track rod 110 and the second track rod 120. The first motor 140 is disposed on the first track rod 110 and is drivenly connected to the second track rod 120 via a drive shaft 160. The first motor 140 is used to drive the third track rod 130 to slide on the first track rod 110 and the second track rod 120. The lifting component 200 is slidably disposed on the third track rod 130, and the second motor 150 is disposed on the third track rod 130. The second motor 150 is used to drive the lifting component 200 to slide on the third track rod 130. Specifically, with the above configuration, the first motor 140 can drive the titration component 300 to move in the Y-axis direction of the coordinate axis, while the second motor 150 can drive the titration component 300 to move in the X-axis direction of the coordinate axis. Furthermore, the simultaneous provision of the first track rod 110 and the second track rod 120 ensures that the third track rod 130 can glide more smoothly. Through this configuration, the titration component 300 can achieve better movement on the horizontal plane.
[0026] In order to enable the titration component 300 to move accurately a predetermined distance on the horizontal plane, in one embodiment, the first motor 140 and the second motor 150 are stepper motors. Specifically, stepper motors can more accurately control the distance moved, thereby enabling the titration component 300 to move accurately a predetermined distance on the horizontal plane.
[0027] In order to allow the titration component 300 to move vertically more effectively, in one embodiment, such as Figure 1 As shown, the lifting assembly 200 includes a lifting rod 210 and a third motor 220. The third motor 220 is mounted on the lifting rod 210, and the titration assembly 300 is slidably mounted on the lifting rod 210. The third motor 220 drives the titration assembly 300 to slide on the lifting rod 210. Specifically, the lifting rod 210 is vertically positioned, and the third motor 220 drives the titration assembly 300 to slide on the lifting rod 210. This configuration allows the titration assembly 300 to move vertically more effectively.
[0028] In order to enable the titration component 300 to accurately move up and down the set distance on the lifting rod 210, in one embodiment, the third motor 220 is a stepper motor. Specifically, the stepper motor can more accurately control the distance of movement, thereby controlling the titration component 300 to accurately move up and down the set distance on the lifting rod 210.
[0029] In order to grip the test tube, in one embodiment, such as Figure 1 As shown, a clamp cylinder 400 is also provided on the movable plate 310. The clamp cylinder 400 is provided on the movable plate 310 and is used to clamp test tubes.
[0030] In order to fix the test tube, in one embodiment, such as Figure 1 As shown, the washing solution titration device 10 for detecting pesticide residues in agricultural products also includes a fixing frame 500. The fixing frame 500 has a grooved fixing structure 510. The fixing frame 500 is used to store the washing solution and to fix the test tube into which the washing solution is dripped. Specifically, the grooved fixing structure 510 on the fixing frame 500 is adapted to the size of the test tube, thus firmly fixing the test tube to the fixing frame 500. Simultaneously, a solution bottle fixing structure is provided inside the fixing frame 500, allowing the washing solution to be stored within the fixing frame 500.
[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
