Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue extraction, in particular to a pesticide residue detection and extraction device. Background Art

[0002] Crops are various plants cultivated in agriculture. They include food crops and cash crops (oil crops, vegetable crops, flowers, grasses, and trees). With the development of agricultural industrialization, the production of agricultural products has become increasingly dependent on exogenous substances such as pesticides, antibiotics, and hormones. The use of pesticides on food, vegetables, fruits, and tea in my country remains high, and the irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer food safety. In severe cases, it will cause consumers to become ill, develop abnormally, or even directly lead to poisoning and death;

[0003] Before crops enter the market, they need to be quickly tested for drug residues. Before testing, a part of the crops needs to be extracted, and then the juice of the crops needs to be extracted (such as green vegetables, celery, etc., for vegetables with more juice, just tear off the leaves). There are also some crops with less juice (such as potatoes, lotus roots, etc.), which need to be sliced ​​and evenly mixed with the extract before extraction, and finally sucked out through a dropper onto a test paper or instrument for testing. The operation is cumbersome. Therefore, a pesticide residue detection and extraction device is proposed. Utility Model Content

[0033] Please continue reading Figure 1 , Figure 2 and Figure 5 The slicing component 200 is placed on the top of the graduated cup 100, including a cover plate 210 connected to the top of the graduated cup 100, a threaded sleeve 220 is threadedly connected to the top of the cover plate 210, a cutter 230 is embedded inside the cover plate 210, a plurality of through holes 231 are provided on the cutter 230, a connecting hole 232 is provided at the center of the cutter 230, the cutter 230 cooperates with the connecting seat 310, and the fruits and vegetables placed on the cutter 230 are sliced ​​and fall into the graduated cup 100 through the through hole 231;

[0034] Please continue reading Figure 2 The force-applying component 300 is connected to the cover plate 210, and includes a connection seat 310 placed on the cover plate 210. An external thread 311 is provided on the outer side of the connection seat 310 to be threadedly matched with the threaded sleeve 220. A handle 312 is integrally formed on the top of the connection seat 310. The connection seat 310 is threadedly mounted in the threaded sleeve 220 through the external thread 311. When the handle 312 is rotated, the connection seat 310 is pressed down or raised along the threaded sleeve 220 under the action of the thread.

[0035] Please continue reading Figure 3-4The stirring component 400 is connected to the graduated cup 100, and moves with the force-applying component 300 to stir the extract in the graduated cup 100. The stirring component 400 includes a threaded sleeve 410 movably connected to the connecting hole 232. A spring 411 is sleeved on the outer side of the threaded sleeve 410, and moves synchronously with the spring 411. The spring 411 is connected to the connecting hole 232 by a bolt. The threaded sleeve 410 is pressed down by the connecting seat 310 and moves along the inner side of the connecting hole 232. A threaded rod 420 is connected to the inner thread of the threaded sleeve 410. The bottom end of the threaded rod 420 is rotatably connected to the inner bottom of the graduated cup 100, and a plurality of stirring blades 421 are connected to the outer side of the threaded rod 420.

[0036] Action 1:

[0037] The connecting seat 310 is pressed down, and the threaded sleeve 410 moves downward along the connecting hole 232 to compress the spring 411. Since the threaded rod 420 is rotatably connected to the graduated cup 100, and the threaded rod 420 and the threaded sleeve 410 are threadedly engaged, when the threaded sleeve 410 moves downward, the threaded rod 420 rotates under the action of the thread, and then the stirring blade 421 stirs the extract in the graduated cup 100, thereby improving the dispersion efficiency between the pesticide residue and the fruits and vegetables;

[0038] Action 2:

[0039] The connecting seat 310 rises, and the spring 411 returns to its original state. At this time, the threaded sleeve 410 moves upward along the connecting hole 232 under the action of the spring 411, driving the threaded rod 420 to rotate in the opposite direction, stirring the extract again;

[0040] Please continue reading Figure 2 and Figure 4 In order to prevent the pesticide from adhering to the inner wall of the graduated cup 100, the threaded rod 420 is connected to a scraper component 500, which includes a driving gear 510 sleeved on the outer side of the threaded rod 420 and moving synchronously with the threaded rod 420. A driven gear 520 is meshedly connected to the outer side of the driving gear 510, and the driven gear 520 is meshed and transmission-coordinated with the tooth groove 110, and a scraper plate 521 is connected to the bottom of the driven gear 520;

[0041] Scraping action:

[0042] The driving gear 510 rotates synchronously with the threaded rod 420, thereby driving the driven gear 520 meshing with the driving gear 510 to move. The driven gear 520 moves along the tooth groove 110 (similar to the planetary gear structure), thereby driving the scraper 521 to clean the inner wall of the graduated cup 100 to prevent agricultural residues from sticking.

[0043] Working principle: When the utility model is used, the handle 312 is rotated, the connection seat 310 is pressed down, and cooperates with the cutter 230 to slice the fruits and vegetables placed on the cutter 230, and the slices fall into the graduated cup 100 through the through hole 231, and the threaded sleeve 410 moves downward along the connection hole 232, and the threaded rod 420 rotates under the action of the thread, and then the extraction liquid placed in the graduated cup 100 is stirred by the stirring blade 421, thereby improving the dispersion efficiency between the pesticide residue and the fruits and vegetables;

[0044] At the same time, the driving gear 510 rotates synchronously with the threaded rod 420, thereby driving the driven gear 520 meshing with the driving gear 510 to move, and the driven gear 520 moves along the tooth groove 110, thereby driving the scraper 521 to clean the inner wall of the graduated cup 100 to prevent the adhesion of agricultural residues.
