Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to a rice grain detection and stratification device. Background Technology

[0002] Rice is rich in carbohydrates, which is one of the main sources of energy for the human body. It also contains a certain amount of protein, fat, vitamins and minerals. Rice with a high moisture content will generate more heat and moisture during storage. If the heat and moisture in the rice pile cannot be dissipated in time, it will easily promote the germination of rice and provide favorable conditions for the growth and reproduction of microorganisms such as mold, leading to moldy rice. Therefore, it is necessary to regularly test the rice at different heights in the rice pile to ensure food safety.

[0003] In the existing technology, the rice detection stratification device does not have a good sealing structure. During the sampling process, especially when taking samples from deeper rice piles, the rice inside the rice detection stratification device may spill due to vibration, tilting, etc., resulting in a reduction in sample volume and contamination of the sample by the external environment, which affects the accuracy of the test results. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rice grain detection and stratification device, which can effectively solve the problem that rice grains in the existing rice grain detection and stratification device will spill due to vibration, tilting or other reasons, resulting in a reduction in sample volume and contamination of the sample by the external environment, thus affecting the accuracy of the detection results.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a rice grain detection and stratification device, including a sampling tube and a pressure rod. The sampling tube has a cavity and multiple closed openings on both sides. Each closed opening has a closing part, and one side of the closed opening has a sliding groove for the closing part to slide and close.

[0009] The pressure rod is installed in the cavity, and the pressure rod in the cavity is provided with multiple circular storage compartments. The outer wall of the storage compartment is attached to the inner wall of the cavity. The storage compartment is provided with a feed port on both sides. The feed port on both sides of the storage compartment is provided with a connecting plate. The connecting plate is provided with two sliders that drive the closing part to slide.

[0010] Furthermore, each side of the closed portion of the sampling tube is provided with a slide rail, which is located on the opposite side of the closed portion. The slide rail is used to connect with the sliders on both sides of the storage compartment.

[0011] Furthermore, one end of the sampling tube is provided with a fixing plate, the middle of the fixing plate is provided with a through hole, and two slots are provided on both sides of the fixing plate.

[0012] Furthermore, the other end of the sampling tube is provided with a rotatably connected base. The base is cone-shaped, and the side of the base near the cavity is provided with multiple springs, which are distributed in a triangular pattern on the base.

[0017] Beneficial effects

[0018] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0019] This invention, through the design of a closure and storage compartments, allows the rice sample testing and stratification device to, during use, cause the connecting plates and sliders on multiple storage compartments within the cavity to slide along the grooves as the pressure rod is pressed down. This allows rice samples of different heights to fall into the storage compartments. The closure and grooves, along with the close fit between the storage compartments and the sampling tube during sampling, prevent rice samples already inside the cavity from spilling out and mixing with other samples in the storage compartments at different heights. Furthermore, it effectively prevents external dust and debris from entering the sampling tube cavity, avoiding contamination of the collected rice samples and ensuring accurate sample testing and analysis.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: A rice grain detection and stratification device, such as Figure 1-4 As shown, it includes a sampling tube 1 and a pressure rod 2. The sampling tube 1 has a cavity 101. Both sides of the sampling tube 1 have multiple closed openings 103. The closed openings 103 have a closing part 4. One side of the closed opening 103 has a sliding groove 104 for the closing part 4 to slide and close.

[0029] By setting the closure part 4 and the slide groove 104, the presence of the closure part 4 during the sampling process can prevent the rice sample that has entered the cavity 101 from leaking out through the closure opening 103, and can effectively prevent external dust, debris and other objects from entering the cavity 101 of the sampling tube 1, avoiding contamination of the rice sample and ensuring accurate detection and analysis of the sample.

[0030] The pressure rod 2 is installed in the cavity 101. The pressure rod 2 in the cavity 101 is provided with multiple circular storage chambers 3. The outer wall of the storage chamber 3 is fitted with the inner wall of the cavity 101. The storage chamber 3 is provided with inlet ports 301 on both sides. Each inlet port 301 on both sides of the storage chamber 3 is provided with a connecting plate 31. The connecting plate 31 is provided with two sliders 32 that drive the closing part 4 to slide. Through the arrangement of the cavity 101 and multiple storage chambers 3, the outer wall of the circular storage chamber 3 on the pressure rod 2 in the cavity 101 is fitted with the inner wall of the cavity 101, which prevents rice from leaking in the gap between the multiple storage chambers 3 and the cavity 101, thus affecting the accuracy of rice detection. This improves the sealing of rice during the sampling process and makes the rice detection device more accurate when detecting rice samples of different heights.

[0031] Furthermore, each of the two closed portions 4 on both sides of the sampling tube 1 is provided with a slide 401. The slide 401 is located on the opposite side of the closed portion 4. The slide 401 is used to connect with the sliders 32 on both sides of the storage compartment 3. Through the setting of the slide 401 and slider 32 on one side of the closed portion 4, when the pressure rod 2 is pressed during use of the rice detection stratification device, the connecting plates 31 and sliders 32 on the multiple storage compartments 3 in the cavity 101 can drive the closed portion 4 to slide in the slide groove 104 during the descent, so that rice samples of different heights fall into the storage compartment 3, thereby increasing the accuracy of rice sampling.

[0032] Furthermore, one end of the sampling tube 1 is provided with a fixing plate 11, the middle of the fixing plate 11 is provided with a through hole 102, and two slots 1101 are provided on both sides of the fixing plate 11.

[0033] Furthermore, the other end of the sampling tube 1 is provided with a rotatably connected base 13. The base 13 is tapered, and a plurality of springs 14 are provided on the side of the base 13 near the cavity 101. The springs 14 are distributed in a triangular pattern on the base 13.

[0034] Furthermore, a support plate 15 is provided on the multiple springs 14 of the base 13, and an annular second limiting plate 24 is provided on the support plate 15. The second limiting plate 24 is located at one end of the pressure rod 2 near the base 13, and the second limiting plate 24 is fixed to the side of the storage compartment 3 near the base 13.

[0035] Furthermore, the other end of the pressure rod 2 is provided with a first limiting plate 23. The first limiting plate 23 is located on the side of the through hole 102 away from the fixed plate 11. Through the cooperation of the spring 14 on the base 13 with the support plate 15, the second limiting plate 24 and the first limiting plate 23, the spring 14 applies elastic pressure to the pressure rod 2 and the storage compartment 3, making the storage compartment 3 fit more tightly with the cavity 101. At the same time, the setting of the first limiting plate 23 and the second limiting plate 24 restricts the movement of the pressure rod 2 within a specified range, maintains the stability of the internal structure, avoids the decrease in sealing due to structural loosening, and prevents rice in the rice detection device from spilling and mixing with rice samples of different heights, affecting the accuracy of the detection structure.

[0036] Furthermore, a fastening plate 21 is provided on the pressure rod 2 at one end of the first limiting plate 23. Both sides of the fastening plate 21 are provided with buckles 22. The buckles 22 are fastened to the slots 1101 on both sides of the fixing plate 11. Through the setting of the buckles 22 on both sides of the fastening plate 21 and the slots 1101 on both sides of the fixing plate 11, when the buckles 22 are fastened to the slots 1101, the pressure rod 2 can form a stable connection structure with the sampling tube 1, preventing the pressure rod 2 from moving during the sampling process and ensuring the sealing of the entire sampler. This fastening structure improves the stability of the closure part 4 and other components, and improves the sealing of the rice detection device.

[0037] Furthermore, one end of the sampling tube 1 fixing plate 11 is provided with a display 12 for observing rice grains, and the display 12 is located on one side of the sampling tube 1.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
