[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] A device for detecting cadmium pollution in rice, such as Figure 1 As shown, the device includes a housing 1, with a detection chamber inside the housing 1. The detection chamber is slidably connected to a cover assembly 6. The cover assembly 6 is used to close the opening of the detection chamber. Specifically, the cover assembly 6 includes a vertical plate 61, a horizontal plate 62, and a magnet 63. The horizontal plate 62 is slidably connected to the detection chamber, and the vertical plate 61 is fixed to the side of the horizontal plate 62. The magnet 63 is provided on the outer side of the vertical plate 61, and a metal sheet 4 is provided at the opening of the detection chamber. The metal sheet 4 is engaged with the magnet 63. During detection, to prevent X-ray leakage, the vertical plate 61 is pushed, causing the magnet 63 to come into contact with the metal sheet 4. Due to magnetic attraction, the cover assembly 6 can effectively seal the opening of the detection chamber.

[0024] To prevent the container 5 from shaking during testing, the surface of the cover assembly 6 is provided with a clamping assembly 7, such as... Figure 2As shown, the clamping assembly 7 is used to clamp the container 5 containing rice samples; the clamping assembly 7 includes a second spring 71 and a clamping plate 72; the surface of the cover assembly 6 has an insertion port, specifically, the surface of the horizontal plate 62 has an insertion port; the inner wall of the insertion port is slidably connected to the clamping plate 72, and the clamping plate 72 is connected to the cover assembly 6 by the second spring 71; the top of the clamping part of the clamping plate 72 has an inclined structure; when the container 5 is inserted, the two clamping plates 72 are pushed away from each other, the second spring 71 is compressed, until the container 5 enters the clamping part plane of the clamping plate 72, and the elastic force of the second spring 71 is used to clamp and fix the container 5;

[0025] To ensure that the center of tablets of different sizes is uniformly placed within the optimal detection area for effective detection, this invention features an adjustable internal support plate 55 in the container 5. Specifically, the container 5 uses materials and structures that do not affect the detection process; for example, it is a transparent structure. The container 5 includes a body 51, a sliding groove 52, a locking groove 53, a slider 54, a support plate 55, a spring 56, a locking pin 57, a connecting rod 58, and a pressing plate 59. Figure 3 and Figure 4 As shown, the chamber 51 has sliding grooves 52 on both sides, and the inner wall of the sliding grooves 52 has multiple locking grooves 53. A support plate 55 is connected inside the chamber 51, and sliders 54 are fixed on both sides of the support plate 55. The sliders 54 are slidably connected to the sliding grooves 52, and locking pins 57 and pressing plates 59 are inserted and slidably connected to both sides of the sliders 54. Each locking pin 57 is connected to the pressing plate 59 via a connecting rod 58, and two connecting rods 58 are connected via a spring 56. When adjusting the height of tablet samples of different sizes, pressing the pressing plate 59 compresses the spring 56, and then moving the slider 54 drives the support plate 55 to rise and fall until the tablet sample reaches the appropriate position, ensuring the center of the tablet sample is evenly within the optimal detection area. Releasing the pressing plate 59 allows the locking pins 57 and pressing plate 59 to reset under the spring force, and the locking pins 57 are inserted into the locking grooves 53 at the appropriate positions.

[0026] To facilitate carrying and support, support components 3 are specifically provided on both sides of the bottom end of the housing 1. These support components 3 rotate to the top of the housing 1 for hand-carrying and movement; they also rotate to the bottom of the housing 1 for support. Each support component 3 includes a locking bolt 31, a rotating disk 32, and a support rod 33. The rotating disk 32 is fixed to the side of the support rod 33, and the support rod 33 is rotatably connected to the housing 1. The locking bolt 31 is threaded to the side of the rotating disk 32, and the locking bolt 31 engages with the housing 1. When carrying the entire unit, the locking bolt 31 is loosened, allowing the support rod 33 to rotate to the top of the housing 1 for easy carrying. During use, the support rod 33 is rotated to... Figure 1 The position shown is such that the threaded hole on the surface of the rotating disk 32 is aligned with the threaded hole on the surface of the housing 1, and then the locking bolt 31 is rotated to fix this state.

[0027] The housing 1 contains a light source irradiation element 8 and a receiver 9. The light source irradiation element 8 includes a connected X-ray tube 81 and a high-voltage power supply 82. The receiver 9 includes a connected detector 91 and a pulse processor 92. The pulse processor 92 is connected to a control screen 2, which is located at the top of the housing 1. The schematic diagram is shown below. Figure 5 As shown, it should be noted that the light source irradiation element 8 and the receiving element 9 are both existing technologies and are mature technologies, and are not within the protection scope of this utility model.

[0028] In use, the rice flaking is first placed inside the silo 51. The optimal detection height is, for example, 5-10 cm from top to bottom in the silo 5. The pallet 55 is moved according to the size of the flaking sample, ensuring the center of the sample is evenly positioned at this height. During movement, the pressing plate 59 is pressed, compressing the spring 56. Then, the sliding block 54 moves the pallet 55 up and down until the sample reaches the appropriate position, ensuring the center of the sample is evenly positioned within the optimal detection area. The pressing plate 59 is then released, allowing the locking pin 57 and pressing plate 59 to reset under spring force. The locking pin 57 is then inserted into the locking groove 53 in the appropriate position. Finally, the vertical plate 61 is pushed, causing the magnet 63 to contact the metal sheet 4. Due to magnetic attraction, the sample can be tested.

[0029] The rice cadmium pollution detection device of this utility model has a container in which the supporting plate can be adjusted according to the size of the rice flaked sample to be tested, ensuring that the uniform center of the flaked sample is always in the optimal detection area, thus improving the accuracy of the detection. In addition, the container adopts a detachable structure and is fixed by clamping, which makes the detection more stable, and is also easy to disassemble and clean.
