Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, and in particular to an aflatoxin content detector for rice soaking. Background Technology

[0002] When processing rice into other products, it is usually necessary to soak the rice. However, after soaking, the rice may produce aflatoxin due to environmental factors or sealing factors. Aflatoxin is quite harmful to the human body. Therefore, it is necessary to test the aflatoxin content of the rice after soaking before processing.

[0003] Current methods typically involve directly testing for mold using a mold detector. The sample is dropped onto a test card, which is then inserted into the detector's port for testing. However, existing detectors do not protect the test port, allowing impurities from the outside air to easily enter and affect the accuracy of the test. To address this issue, we propose a new aflatoxin content detector for rice soaking. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies mentioned in the background section by proposing an aflatoxin content detector for rice soaking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aflatoxin content detector for soaking rice includes a mold detector and a detection port located at the end of the mold detector. Mounting seats are provided on both sides of the bottom end of the detection port of the mold detector. A rotating shaft is provided between the two sets of mounting seats. A protective cover is sleeved on the outside of the rotating shaft. The protective cover shields and protects the detection port of the mold detector.

[0007] A protective cover can be used to protect the detection port of the mold detector, preventing impurities from the outside air from entering the detection port when the mold detector is placed, thus improving the detection effect.

[0008] Preferably, the mounting base is provided with a mounting rod at its end, the mounting rod is located below the protective cover, a mounting pulley is sleeved at the middle position of the outer side of the mounting rod, a traction rope is sleeved on the outer side of the mounting pulley, and the top end of the traction rope is connected to the bottom end of the protective cover.

[0009] The protective cover can be pulled by a pulley and a traction rope, allowing it to return to its original position. When the test card is inserted, the protective cover can support the bottom of the test card via the traction rope.

[0010] Preferably, the mounting rod is provided with a mounting plate on its exterior, and two sets of mounting plates are provided, with the two sets of mounting plates located on both sides of the mounting pulley;

[0011] The rotation of the installed pulley can be limited on both sides, thereby improving the rotation effect of the installed pulley.

[0012] Preferably, a torsion spring is sleeved on the outside of the mounting rod. The torsion spring is located between the mounting plate and the mounting pulley. One end of the torsion spring is fixedly connected to the mounting pulley, and the other end of the torsion spring is fixedly connected to the end of the mounting plate.

[0013] The torsion spring can support the mounting pulley, allowing the mounting pulley to return to its original position after rotation, thus enabling the traction rope to pull the protective cover to return to its original position.

[0014] Preferably, the protective cover has a placement groove on its back, the top of the placement groove is open, and a guide roller is provided at the top of the placement groove;

[0015] This allows the bottom of the detection card to contact the guide roller, thus enabling the detection card to move more effectively.

[0016] Preferably, multiple sets of rubber positioning blocks are arranged at equal horizontal intervals inside the placement groove;

[0017] This can increase the contact area between the rubber positioning block and the detection card, thereby improving the stability of the detection card after insertion.

[0018] Preferably, the rubber positioning block has multiple sets of adsorption holes on its front side;

[0019] This allows the rubber positioning block to deform under pressure, further increasing the stability of the detection card.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model can protect the detection port of the mold detector with a protective cover to prevent external impurities from entering and affecting the detection effect. When the protective cover is unfolded, it can support the bottom of the detection card when the detection card is inserted, so that the detection stability after the detection card is inserted is better.

[0022] 2. This utility model can restore the protective cover by pulling it with a torsion spring and traction rope. When the test card is removed, it will automatically restore itself for protection. At the same time, the protective cover supports the bottom of the test card, so that the rubber positioning block is pressed and the adsorption hole is adsorbed, thereby making the stability of the test card after insertion and preventing shaking, and further improving the accuracy of the test.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 The aflatoxin content detector for rice soaking shown has a detection port on the front of the mold detector 1. Mounting bases 3 are fixedly installed on both sides below the detection port. A rotating shaft 4 is fixedly installed between the two sets of mounting bases 3. A protective cover 2 is placed on the front of the detection port, with its bottom end fitted onto the outside of the rotating shaft 4, allowing the protective cover 2 to rotate. A placement groove 5 is provided on the back of the protective cover 2, and a guide roller 6 is movably installed at the top of the placement groove 5. The guide roller 6 can rotate. Rubber positioning blocks 7 are evenly fixedly installed laterally inside the placement groove 5. Multiple sets of adsorption holes 8 are then formed on the front of the rubber positioning blocks 7.

[0030] For a detailed description of the mounting rod 9 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4A mounting rod 9 is fixedly installed at the end of the mounting base 3. The mounting rod 9 is located directly below the protective cover 2. A mounting pulley 10 is then sleeved at the middle position of the mounting rod 9. A traction rope 11 is wound around the outside of the mounting pulley 10. The top end of the traction rope 11 is fixedly installed to the bottom end of the protective cover 2. Then, mounting plates 12 are fixedly installed on both sides of the mounting pulley 10 on the outer wall of the mounting rod 9. Two sets of torsion springs 13 are sleeved on the outside of the mounting rod 9. The torsion springs 13 are located between the mounting pulley 10 and the mounting plates 12, so that one end of the torsion spring 13 is fixedly connected to the mounting plate 12, and the other end of the torsion spring 13 is fixedly connected to the end of the mounting plate 12.

[0031] Working principle: When using this utility model, the protective cover 2 can be rotated directly to open the detection port on the mold detector 1. Then, the detection card is inserted into the detection port and the mold detector 1 detects aflatoxin. At the same time, the torsion spring 13 drives the mounting pulley 10 to move, which in turn drives the traction rope 11 to move. This causes the traction rope 11 to pull the protective cover 2 back to its original position, thus supporting and limiting the bottom of the detection card, resulting in good stability of the detection card.

[0032] Meanwhile, the protective cover 2 squeezes the bottom of the test card by the rubber positioning block 7, causing the rubber positioning block 7 to deform after being squeezed. This causes the interior of the adsorption hole 8 to deform and generate adsorption force, thereby further adsorbing the test card and making it more stable. When the test card is removed from the inside of the detection port on the mold detector 1, the protective cover 2 restores itself and restores the detection port, thus completing the protection of the detection port and preventing external dust and impurities from entering and causing contamination.

[0033] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
