Description

Technical Field

[0001] The utility model relates to the technical field of grain detection, and more specifically, to a grain mycotoxin detection device. Background Art

[0002] Food that has been stored for a long time is prone to produce fungal toxins. For example, wheat and corn are prone to produce aflatoxin, zearalenone, fumonisin and vomitoxin during storage. These fungal toxins are harmful to the human body, so food mycotoxin testing is very important.

[0003] Application No. 2023205969853 discloses a detection device for detecting mycotoxins in grains, comprising a housing and a sampling box. The housing is provided with a groove 1, a piston 1 is provided in a sliding sealing sleeve within the groove 1, a liquid outlet pipe is fixedly connected to one end of the housing, a liquid outlet mechanism is provided on the outer wall of the liquid outlet pipe, a sampling box is provided on one side of the liquid outlet mechanism, and a spring 1 is fixedly connected to the inner wall of the groove 1 on the side of the piston 1 away from the liquid outlet mechanism. Beneficial effects: By providing the piston 1 within the housing, a cavity for storing a mycotoxin reagent solution is formed within the groove 1, and the outer wall of the housing is also provided with a glass window (not shown) to observe the residual solution inside. The sampling box can be used to sample grain samples, and then the sampling box is inserted into the liquid outlet pipe at one end of the housing.

[0004] Although the detection reagent in the shell of the above-mentioned device flows out through the liquid outlet hole on the liquid outlet tube, and a sealing and reset mechanism is provided to prevent liquid leakage, when the above-mentioned device is actually used, the reagent inside the shell will still come into contact with the outside air. Since only a few drops of reagent are needed for a single test, the excess reagent stored in the device is prone to deterioration and failure. In addition, the internal structure of the device is compact, making it difficult to disassemble, clean and reuse. Utility Model Content

[0005] In order to overcome the problem that the detection reagents are easily deteriorated and lose their effectiveness in the above background, the utility model provides a grain mycotoxin detection device.

[0006] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0007] A grain mycotoxin detection device comprises an outer shell, a top cover detachably mounted on the top of the outer shell, and a turntable rotatably mounted inside the outer shell and the top cover; the turntable rotates along the vertical axis of the outer shell and the top cover as a whole; a through hole is provided in the middle of the top cover; an operating handle is provided in the middle of the top of the turntable, and the operating handle passes through the through hole; a plurality of rubber ball mounting grooves are evenly arranged around the side wall of the turntable, a rubber ball is provided in each of the rubber ball mounting grooves, and a mycotoxin detection reagent is provided inside the rubber ball; a discharge port is provided on the side wall of the outer shell, a detachable rubber sleeve is sleeved on the discharge port, and a rubber sleeve outlet is provided on the end of the rubber sleeve away from the discharge port.

[0008] In the above embodiment, the detection reagent is placed in multiple rubber balls, and the rubber balls are placed one by one in each rubber ball mounting groove. By turning the operating handle, when the rubber ball mounting groove rotates to the discharge port with the turntable, the balls fall and enter the rubber sleeve. By crushing the balls, the reagent inside them is allowed to drip into the sampling box through the rubber sleeve outlet for detection. After a single test is completed, the rubber sleeve can be removed and replaced to avoid cross contamination.

[0009] It can be seen that in the above process, the reagents in each rubber ball are not related to each other, and cross-infection will not occur during use. By designing a single rubber ball to store reagents, waste can also be avoided.

[0010] Preferably, the top of the side wall of the shell and the internal threaded connection of the top cover.

[0011] Preferably, a feed port is provided on the top edge of the top cover, and a detachable feed port cover is sleeved on the feed port.

[0012] Preferably, an anti-slip ring is provided on the side wall of the discharge port.

[0013] Preferably, a protrusion is fixedly mounted on the inner wall of the rubber sleeve.

[0014] Preferably, the diameter of the rubber sleeve outlet is smaller than the diameter of the rubber ball.

[0015] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0016] The utility model provides a device for detecting mycotoxins in grains, which can prevent the detection reagents inside the device from being contaminated and deteriorated. Specifically:

[0017] 1) Set up rubber balls and put the test reagents into the small rubber balls. Puncture / squeeze one rubber ball at a time to allow the reagents in the rubber balls to enter the sampling box for testing, which will not cause the test reagents to deteriorate and become ineffective.

[0018] 2) The outer shell and top cover are provided to facilitate the disassembly and maintenance of the turntable inside the two;

[0019] 3) The feed port and feed port cover are set, and the rubber ball can be directly placed into the rubber ball installation groove through the feed port, which is convenient for rapid loading during continuous testing;

[0020] 4) A rubber sleeve and a protrusion are provided. When the rubber ball enters the rubber sleeve, the rubber ball can be crushed by squeezing the rubber sleeve, allowing the reagent to flow out through the rubber sleeve outlet. Subsequently, only the rubber sleeve needs to be replaced to prevent cross-infection of the reagents. The setting of the protrusion makes it easier to puncture the rubber ball when squeezing the rubber sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solution of the present utility model is further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] See also Figure 1-6A grain mycotoxin detection device comprises a shell 1, a top cover 2 detachably mounted on the top of the shell 1, and a turntable 8 rotatably mounted inside the shell 1 and the top cover 2; the turntable 8 rotates along the vertical axis of the shell 1 and the top cover 2 as a whole; a through hole 3 is provided in the middle of the top cover 2; an operating handle 4 is provided in the middle of the top of the turntable 8, and the operating handle 4 passes through the through hole 3; a plurality of rubber ball mounting grooves 81 are evenly arranged around the side wall of the turntable 8, a rubber ball 9 is provided in each rubber ball mounting groove 81, and a mycotoxin detection reagent is provided inside the rubber ball 9; a discharge port 6 is provided on the side wall of the shell 1, a detachable rubber sleeve 7 is sleeved on the discharge port 6, and a rubber sleeve outlet 72 is provided on the end of the rubber sleeve 7 away from the discharge port 6.

[0036] like Figure 1 and Figure 5-6 As shown, in some preferred embodiments, the top of the side wall of the shell 1 and the internal threaded connection of the top cover 2, the shell 1 and the top cover 2 are hollow cylinders as a whole, and the top is open, and the shell 1 and the top cover 2 are fixed by screwing, which is convenient for disassembly.

[0037] like Figure 3 and Figure 5-6 As shown, in some preferred embodiments, a feed port 5 is provided at the top edge of the top cover 2, and a detachable feed port cover 10 is sleeved on the feed port 5. When the rubber ball mounting groove 81 rotates, it will be located directly below the feed port 5. The size of the feed port 5 is larger than the size of the rubber ball 9. When continuous testing is required, the feed port cover 10 is removed and the rubber ball 9 is placed through the feed port 5.

[0038] like Figure 2 As shown, in some preferred embodiments, an anti-slip ring 61 is provided on the side wall of the discharge port 6. The anti-slip ring 61 can be a rubber band, which is sleeved on the outer wall of the discharge port 6. Its purpose is to increase the friction between the rubber sleeve 7 and the discharge port 6 to prevent it from falling off.

[0039] like Figure 2 As shown, in some preferred embodiments, a protrusion 71 is fixedly installed on the inner wall of the rubber sleeve 7. When the rubber ball 9 enters the rubber sleeve 7, it is necessary to pinch the rubber sleeve 7 by hand and crush the rubber ball 9 to allow the detection reagent in the rubber ball 9 to enter the sampling box through the discharge port 6 for detection. During this process, the design of the protrusion 71 is intended to quickly break the rubber ball 9.

[0040] In some cases, the rubber ball 9 may also be a sealed plastic ball.

[0041] like Figure 2As shown, in some preferred embodiments, the diameter of the rubber sleeve outlet 72 is smaller than the diameter of the rubber ball 9. The size of the rubber sleeve outlet 72 is designed to facilitate the positioning of the rubber ball 9, so that the rubber ball 9 is located inside the rubber sleeve 7 before being crushed, thereby preventing the rubber ball 9 from falling directly through the rubber sleeve outlet 72.

[0042] The specific working principle of the above-mentioned device is as follows: when testing is required, align the discharge port 6 on the outer shell 1 with the sampling box that has collected the wheat and corn samples to be tested, and rotate the operating handle 4 to allow the turntable 8 and the rubber ball mounting groove 81 on its side to drive the rubber ball 9 to rotate. When a rubber ball 9 is located at the discharge port 6, it will fall into the rubber sleeve 7 through the discharge port 6. The design of the rubber sleeve outlet 72 will limit the rubber ball 9 to prevent the rubber ball 9 from falling directly through the rubber sleeve outlet 72. At this time, you can use your thumb and index finger to pinch the rubber sleeve 7. The protrusion 71 on the inner wall of the rubber sleeve 7 can quickly break the rubber ball 9. Finally, the detection reagent inside the rubber ball 9 enters the sampling box through the rubber sleeve outlet 72 for testing; when comparative sampling is required, you can replace the rubber sleeve 7, and then continue to rotate the operating handle 4 to repeat the above operation.

[0043] When the rubber balls 9 need to be replenished, the feed port cover 10 is disassembled and the rubber balls 9 are placed through the feed port 5 .

[0044] When the interior of the device needs to be cleaned and sterilized, the outer shell 1 and the top cover 2 can be disassembled.

[0045] The utility model device is used for fungal toxin detection experiments on grains (wheat, corn) and other grains.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
