Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to a sampling structure for detecting pesticide residues in fruits and vegetables. Background Technology

[0002] Fruits and vegetables, short for "fruits and vegetables," are an indispensable basic food category in people's daily diet. Their core value lies in two aspects: first, nutritional supply, being rich in vitamins (such as vitamin C, which is more abundant in the peel than in the flesh), inorganic salts, enzymes, and dietary fiber, while being low in protein and fat, effectively balancing the health burden of high-fat and high-protein staple foods; second, flavor enhancement, containing organic acids, aromatic substances, and pigments that enrich the taste of dishes, helping to combine healthy eating with gustatory enjoyment. During the harvesting process, pesticide residue testing is necessary, thus requiring the use of sampling structures. Existing sampling structures typically involve picking and collecting fruits and vegetables for testing. However, this presents several problems. For example, when sampling deep into fields, the dense planting can easily damage vegetables as staff move around. Furthermore, sampling taller fruits requires external equipment or tools to reach the sampling height, reducing sampling efficiency. Therefore, we propose a sampling structure for detecting pesticide residues in fruits and vegetables to address these issues. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figure 1 and Figure 2 A sampling structure for detecting pesticide residues in fruits and vegetables includes a housing 1. A telescopic rod 16 is bolted to the right side of the inner cavity of the housing 1. A spring 17 is sleeved on the surface of the telescopic rod 16. A movable plate 15 is bolted to one side of the spring 17. A push rod 11 is bolted to one side of the movable plate 15. An adjusting seat 10 is bolted to one side of the push rod 11, extending through to the outside of the housing 1. A protective shell 3 is welded to the side of the adjusting seat 10. An electric push rod 4 is bolted to one side of the inner cavity of the protective shell 3. A sliding plate 5 is bolted to one side of the electric push rod 4. A push column 6 is bolted to one side of the sliding plate 5. A sliding plate 7 is bolted to one side of the push column 6, extending through to the inner cavity of the adjusting seat 10. A blade 8 is bolted to one side of the sliding plate 7.

[0021] Furthermore, a handle 2 is welded to the right side of the housing 1, and an anti-slip sleeve is fitted onto the surface of the handle 2 to prevent slipping.

[0022] Furthermore, grooves are provided on both sides of the inner cavity of the protective shell 3, and both sides of the sliding plate 5 are slidably connected to the inner cavity of the grooves by sliders. Through the grooves, the sliders can slide in the inner cavity, which improves the sliding stability of the sliding plate 5.

[0023] Furthermore, a net bag 9 is bolted to the bottom of the protective shell 3. The center of the net bag 9 is located directly below the knife 8. The net bag 9 facilitates the collection of fallen fruits and vegetables.

[0024] Furthermore, the surface of the adjusting seat 10 is provided with a through groove, and one side of the cutter 8 is attached to the inner wall of the through groove. The through groove improves the stability of the sliding plate 7.

[0025] Example 2: refer to Figures 1-3 A sampling structure for detecting pesticide residues in fruits and vegetables includes a cover plate 13 attached to the surface of a shell 1. A screw cap 12 is threadedly connected to one side of the surface of the cover plate 13. A locking bolt 18 is welded to one end of the screw cap 12. A screw hole 14 is provided on one side of the surface of a push rod 11. The inner cavity of the screw hole 14 is threadedly connected to the surface of the locking bolt 18. The screw cap 12 and the screw hole 14 facilitate locking of the push rod 11, preventing the push rod 11 from shaking and shrinking during sampling, thus improving the stability of sampling.

[0026] Brief description of usage: When sampling and testing fruits and vegetables deep or high up, the user turns the cap 12 in reverse. This reverse rotation of the cap 12 causes the locking bolt 18 to turn in reverse, disengaging it from the inner cavity of the screw hole 14. At this point, the limiting pressure on the push rod 11 is released, and the telescopic rod 16 and spring 17 automatically reset. The spring 17 and telescopic rod 16 facilitate the movement of the moving plate 15, which in turn moves the push rod 11. The push rod 11 then moves the adjusting seat 10, which in turn moves the cutter 8. Since the surface of the push rod 11 has several screw holes 14, the user can adjust it according to their needs. The length of the blade 8 is adjusted as needed. After adjustment, the user turns the screw cap 12 clockwise to insert the locking bolt 18 into the inner cavity of the screw hole 14, which facilitates locking and limiting the push rod 11. Then, the user holds the handle 2, aligning the distance between the two blades 8 with the harvested fruits and vegetables. The user then starts the electric push rod 4 through the external controller. The electric push rod 4 pushes the sliding plate 5 to move, which in turn pushes the push column 6 to move. The push column 6 pushes the slide plate 7 to move, which in turn moves the blade 8. The movement of the blade 8 harvests the fruits and vegetables, which then fall into the inner cavity of the net bag 9. Finally, the user can retrieve and inspect the harvested fruits and vegetables.

[0027] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
