[0002] Grains refer to the seeds of grasses, mainly including rice, wheat, millet, soybeans, and other miscellaneous grains. They are the traditional staple food of many Asian people and a major source of energy for the human body.

[0003] After grain harvesting, to ensure food safety, maintain grain quality, and promote sustainable agricultural development, it is generally necessary to test the imperfection rate of the grain. This requires the use of a dedicated grain testing device. Existing grain testing devices have two built-in industrial cameras that capture images of each grain from all angles. AI models are then used to automatically compare and identify the captured images to determine whether the grain is imperfect. However, the functional structure of the feed inlet of existing testing devices is too simple and cannot effectively prevent external impurities from entering the testing device, thus hindering accurate grain testing during operation. Utility Model Content

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Example

[0026] Please refer to Figures 1-4 This embodiment provides a detection device for grain imperfection rate, including a detector 1, a recycling frame 2, and a feed inlet 3. A spring 4 is provided between the inner side of the feed inlet 3 and the detector 1. A sealing component 5 is provided between the feed inlet 3 and the spring 4. The sealing component 5 includes a metal ring 51 and a sealing block 52. A metal rod 53 is provided between the inner sides of the metal ring 51. A metal rod 54 is provided between the metal rod 53 and the bottom surface of the sealing block 52. The metal ring 51 and the sealing block 52 are both movably engaged in the feed inlet 3 by the spring 4. The top surface of the sealing block 52 is designed to be rounded. A protruding rod 6 is provided on the surface of the sealing block 52 along the vertical direction. The top end of the protruding rod 6 extends to the top of the feed inlet 3.

[0027] In this embodiment, the operator can put the grain to be tested into the feed inlet 3, so that the grain is above the sealing block 52. Then, the operator can grasp the protruding rod 6 and press it down. During the pressing process, the protruding rod 6 drives the sealing block 52 to move downward. The sealing block 52 drives the metal rod 54, the metal rod 53 and the metal ring 51 to move downward at the same time. During the downward movement of the metal ring 51, the spring 4 is compressed and contracts. At this time, a leakage port is exposed between the sealing block 52 and the feed inlet 3, so that the grain located between the sealing block 52 and the feed inlet 3 can enter the detector 1 for detection. After the grain is completely entered into the detector 1, the protruding rod 6 is released and the spring 4 rebounds, thereby driving the sealing component 5 to reset.

[0028] During the grain testing process, staff can pre-load the next batch of grain into feed inlet 3. After the previous batch of grain has been tested, the grain to be tested in feed inlet 3 can be loaded into the testing instrument 1, thus improving testing efficiency.

[0029] When external impurities fall into the feed inlet 3, the sealing block 52 can effectively restrict the impurities, preventing them from falling into the detector 1 and affecting the accuracy of subsequent grain imperfection rate detection.

[0030] As an optional implementation, the feed inlet 3 has an opening 31, and a hollow rod 7 is sleeved on the outside of the protruding rod 6. The surface of the hollow rod 7 is provided with a scraper 71 located inside the feed inlet 3. Both the front and back of the scraper 71 are provided with arc surfaces.

[0031] In this embodiment, by feeding the grain to be tested into the feed inlet 3 and then applying pressure to the hollow rod 7, the grain in the feed inlet 3 can be pushed out through the opening 31 each time by the scraper 71, thereby ensuring the amount of grain to be tested in the feed inlet 3, and there is no need to use tools to weigh the grain before testing.

[0032] As an optional implementation, the surface of the hollow rod 7 is provided with a connecting plate 72, and the bottom surface of the connecting plate 72 is provided with an arc-shaped baffle 73 sleeved on the outside of the feed inlet 3. The arc-shaped baffle 73 is located at the position of the opening 31 of the feed inlet 3.

[0033] In this embodiment, the arc-shaped baffle 73 is used to limit and block the grain being placed, thereby ensuring that the grain placed by the staff can pass over the bottom surface of the scraper 71 each time, making it easier to determine the amount of grain placed and avoiding the inconvenience caused by repeatedly placing grain due to insufficient grain.

[0034] As an alternative implementation, the hollow rod 7 is provided with a handle 74 on its outer side.

[0035] In this embodiment, it is convenient for the operator to rotate and apply pressure to the hollow rod 7 using the handle 74.

[0036] As an optional implementation, the top surface of the scraper 71 is provided with a connecting plate 2 75, and the top surface of the connecting plate 2 75 is provided with a through hole 1 8. The side of the feed inlet 3 is provided with a connecting plate 3 9, and the top surface of the connecting plate 3 9 is provided with a through hole 2 91 corresponding to the through hole 1 8. A rod 10 is inserted between the through hole 1 8 and the through hole 2 91.

[0037] In this embodiment, inserting the rod 10 between the connecting plate 2 75 and the connecting plate 3 9 can achieve the blocking effect on the arc-shaped baffle 73, preventing the arc-shaped baffle 73 from easily rotating and affecting the blocking and limiting effect on the grain.

[0038] As an alternative implementation, the top of the insertion rod 10 extends above the connecting plate 2 75.

[0039] In this embodiment, it is more convenient for workers to grasp the insertion rod 10.

[0040] As an optional implementation, a receiving frame 11 is sleeved on the outside of the feed inlet 3, and the receiving frame 11 is located on the top surface of the detector 1.

[0041] In this embodiment, during the rotation of the scraper 71, the grains that cross the bottom surface of the scraper 71 fall outward through the opening 31 into the receiving frame 11, thereby achieving the collection of grains.

[0042] As an alternative implementation, the top surface of the metal ring 51 is set as an inclined surface.

[0043] In this embodiment, grains that fall onto the metal ring 51 through the sealing block 52 and the leakage port of the feed inlet 3 can slide off the inclined surface, thus avoiding grain residue.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
