Description

Technical Field

[0001] The utility model relates to the technical field of wolfberry pesticide residue inspection, in particular to a pesticide residue inspection box for wolfberries. Background Technique

[0002] Wolfberry is a plant of the Solanaceae family and the Lycium genus. Wolfberry is a general term for commercial wolfberry fruits, the plant Lycium barbarum, and other Lycium species. When planting wolfberries, pesticides are added to control insects and prevent them from damaging the wolfberries. However, this kind of pesticide is also harmful to the human body. If it is not cleaned thoroughly, it will cause food poisoning and pose a threat to human health. Therefore, it is necessary to detect the pesticides in wolfberries.

[0003] For example, a Chinese patent with the application number "202122799730.0" and the name "A special pesticide residue inspection box for wolfberries" discloses a special pesticide residue inspection box for wolfberries, including a frame body. Inside the frame body, there are respectively arranged a cleaning box, a liquid collecting box, and a detection box... The output end of the motor is connected with a stirring frame through a driving shaft. By setting an immersion card assembly in the utility model, when the user places the detection card on the placement net, the sliding sleeve can be moved downward, so that the pressing rod moves downward and pushes the placement net downward. After the placement net moves downward, the spring can be extruded, causing the spring to be compressed under force. At the same time, the detection card is completely immersed in the cleaning water, thereby increasing the dipping amount of the pesticide residue liquid, preventing the dipping amount of the pesticide residue liquid from being too small and affecting the subsequent detection of it, and then improving the detection effect of the pesticide.

[0004] In the cleaning box of the above patent, there is a lack of a structure for limiting the wolfberries during soaking and cleaning, and it is impossible to ensure that the wolfberries are completely immersed in the cleaning liquid during the soaking and cleaning process. Some wolfberries may have a relatively high content of wolfberry polysaccharides and less sugar, so the quality of the wolfberries is lighter, and they may float on the liquid surface. The floating of wolfberries on the liquid surface is not conducive to cleaning them thoroughly, affecting the accuracy of the subsequent wolfberry pesticide residue detection data. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a pesticide residue inspection box for wolfberries is proposed.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Refer to Figure 1-7 , a pesticide residue inspection box for wolfberries provided by the present invention: including a frame 1, an immersion cleaning tank 2 is fixedly installed at the top of the inner wall of the frame 1, a stirring mechanism is arranged on the immersion cleaning tank 2, and a lower pressure limiting mechanism for limiting wolfberries is arranged at a position near the top of the inner wall of the immersion cleaning tank 2. A liquid collection tank 3 and a detection tank 4 are arranged at the bottom of the frame 1;

[0029] The lower pressure limiting mechanism includes an electric telescopic rod 5 fixedly installed at the top of the immersion cleaning tank 2. The telescopic end of the electric telescopic rod 5 is fixedly connected with a lower pressure limiting plate 6. A plurality of filter holes 7 are opened on the lower pressure limiting plate 6. The size of the lower pressure limiting plate 6 is adapted to the inner cavity size of the immersion cleaning tank 2.

[0030] Two sets of sliding mechanisms are arranged at the bottom of the inner wall of the detection tank 4. A mobile detection table 8 is arranged between the tops of the two sets of sliding mechanisms. A placement seat 9 is fixedly connected to the top of the mobile detection table 8. A detection card 10 is placed on the top of the placement seat 9. And heating plates 11 are fixedly installed on both sides of the inner wall of the detection tank 4.

[0031] The sliding mechanism includes a slide rail 12 fixedly installed at the bottom of the inner wall of the detection tank 4. A slide block 13 is slidably connected inside the slide rail 12. The top of the slide block 13 is fixedly connected to the bottom of the mobile detection table 8;

[0032] By setting up the sliding mechanism, it is convenient to push and pull the mobile detection table 8 back and forth. Thus, when the staff takes and places the detection card 10 into and out of the detection box 4, the mobile detection table 8 can be pulled out to the outside of the detection box 4, enabling the staff to take and place the detection card 10 outside the detection box 4. Compared with the traditional way of taking and placing the detection card 10 inside the detection box 4, there is a larger space for taking and placing operations, which is beneficial for the staff to conveniently take and place the detection card 10, thereby effectively improving the detection efficiency.

[0033] The stirring mechanism includes a driving motor 14 and two rotating shafts 15. The driving motor 14 is fixedly installed at the bottom of the soaking and cleaning tank 2. The output end of the driving motor 14 is fixedly connected with a driving bevel gear 16. Both of the two rotating shafts 15 are rotatably installed through the bottom of the soaking and cleaning tank 2. At the bottom ends of both of the two rotating shafts 15, a pulley 17 is fixedly connected. A transmission belt 18 is connected between the outer surfaces of the two pulleys 17. At the bottom end of one of the rotating shafts 15, a driven bevel gear 19 is fixedly sleeved. The outer surface of the driven bevel gear 19 is meshed with the outer surface of the driving bevel gear 16. Stirring frames 20 are fixedly connected to the outer surfaces of both of the two rotating shafts 15;

[0034] By setting up the stirring mechanism, the wolfberries in the soaking and cleaning tank 2 can be stirred and cleaned, facilitating thorough cleaning of the wolfberries.

[0035] At the four corners of the top of the pressing limit plate 6, limiting rods 21 are fixedly connected. The top ends of the limiting rods 21 movably penetrate through the soaking and cleaning tank 2 and the frame body 1 and extend to the top of the frame body 1. By setting up the limiting rods 21, the pressing limit plate 6 during the up and down movement can be limited, effectively improving the stability of the up and down movement of the pressing limit plate 6.

[0036] On one side of the soaking and cleaning tank 2 and below the pressing limit plate 6, a feeding hopper 22 is fixedly communicated. An electromagnetic valve 23 is arranged on the feeding hopper 22. And at the bottom of the soaking and cleaning tank 2, a discharging pipe 24 is fixedly communicated. An electromagnetic valve 25 is arranged on the discharging pipe 24.

[0037] A filter frame 26 is lapped on the top of the liquid collection tank 3, and the filter frame 26 is located below the discharging pipe 24.

[0038] Working principle: In the initial state, both solenoid valve 1 23 and solenoid valve 2 25 are in the closed state. When in use, first open solenoid valve 1 23, and add the goji berries to be detected from the feeding hopper 22 into the soaking and cleaning tank 2. At the same time, inject an appropriate amount of cleaning liquid into the soaking and cleaning tank 2 from the feeding hopper 22. Then close solenoid valve 1 23, and start the electric telescopic rod 5 to make it extend downward, driving the downward pressure limiting plate 6 to move downward. Thus, the goji berries floating on the liquid surface are pressed into the liquid by the downward pressure limiting plate 6, so that all the goji berries are completely immersed in the cleaning liquid, avoiding the goji berries floating on the liquid surface, which is beneficial to the subsequent thorough cleaning of the goji berries, improving the cleaning efficiency of the goji berries, and during the downward movement of the downward pressure limiting plate 6, through the setting of the filtering holes 7, the goji berries can be filtered and intercepted to avoid moving above the downward pressure limiting plate 6;

[0039] After the downward pressure limiting mechanism completely presses the goji berries and immerses them in the cleaning liquid, start the driving motor 14. The output end of the driving motor 14 rotates to drive the driving bevel gear 16 to rotate, and then drives the driven bevel gear 19 meshing with it to rotate. And through the cooperation of the two belt pulleys 17 and the transmission belt 18, drive the two rotating shafts 15 to rotate synchronously, and drive the stirring frame 20 to rotate synchronously to stir and clean the goji berries in the soaking and cleaning tank 2;

[0040] When the cleaning of the goji berries in the soaking and cleaning tank 2 is completed, turn off the driving motor 14 and open solenoid valve 2 25, so that the cleaned cleaning liquid and goji berries in the soaking and cleaning tank 2 are discharged from the discharging pipe 24. The goji berries are filtered and intercepted and collected through the filtering frame 26, and the cleaned cleaning liquid passes through the filtering frame 26 and is discharged into the liquid collecting tank 3. Then the staff pulls the mobile detection table 8 to the side away from the detection box 4. Through the setting of the sliding mechanism, it is convenient for the staff to pull the mobile detection table 8 back and forth. Then put the detection card 10 into the liquid collecting tank 3 to dip an appropriate amount of the cleaned cleaning liquid. Then place the detection card 10 on the placement table, and push the mobile detection table 8 to the side close to the detection box 4, and push the mobile detection table 8 into the detection box 4, that is, push the detection card 10 into the detection box 4 for detection. Immediately start the heating plate 11 to heat the inner cavity of the detection box 4, which is convenient for the detection card 10 to be detected at an appropriate temperature, and is beneficial to improving the accuracy of the detection data.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
