The rotary worktable 21 has a worm gear transmission mechanism inside that is driven by the servo motor 25. A double-layer connecting plate 24 is installed on the table surface of the rotary worktable 21.

[0073] Lower linear module 22: Installed to the lower layer of double-layer connecting plate 24 through first housing 222. The lower linear module 22 is driven by first drive motor 221 to move first slider 226. Vertical cylinder 224 is installed on the side of first slider 226 through side connecting plate 223.

[0075] In particular, in terms of spatial relationship, the transparent hopper 225 and the receiving and turning table 233 are parallel to each other and located on a straight line, which allows the upper linear module 23 and the lower linear module 22 to move independently in a linear manner, while the two can coordinate with each other to transfer rice samples between the transparent hopper 225 and the receiving and turning table 233.

[0076] Material receiving tilt table 233:

[0077] The receiving and tilting table 233 includes an L-shaped connecting plate 2335L.

[0078] The detection method of the multi-parameter integrated rapid rice quality detection device includes the following steps:

[0079] Place the sample: Pour the rice sample into the black material tray 2332, and use the spring plate 2337 to hold the black material tray 2332 in the receiving hopper 2331.

[0080] Appearance and chalky grain rate detection: Under the combined action of the rotary worktable 21 of the rotary conveying module 2 and the upper linear module 23, the black material tray 2332 moves to the bottom of the appearance detection module 3, with the ring light 35 as the light source; the background color of the black material tray 2332 enables the appearance detection camera 33 to accurately identify the appearance outline of the rice, thereby judging the appearance quality and chalky grain rate.

[0081] Moisture detection: Under the combined action of the rotary worktable 21 of the rotary conveying module 2 and the upper linear module 23, the black material tray 2332 moves to the bottom of the moisture detection module 4. The moisture sensor 45 is driven by the moving module 43 and inserted into the black material tray 2332 to complete the moisture detection.

[0082] Turning over: The light from the ultraviolet lamp 55 of the chalky grain rate detection module cannot pass through the black material tray 2332, so the upper linear module 23 and the lower linear module 22 move to the same position, and the receiving hopper 2331 is driven by the flipping motor 2334 to pour the rice sample into the transparent material hopper 225.

[0083] Amylose content detection: When the vertical cylinder 224 is raised, the transparent hopper 225 moves between the ultraviolet lamp 55 and the optical sensor 53 under the combined action of the rotary worktable 21 of the rotary conveying module 2 and the lower linear module 22. Based on the difference in spectral absorption characteristics between amylose and amylopectin, the amylose content of rice is detected.

[0084] Odor detection during aging: Under the combined action of the rotary worktable 21 of the rotary conveying module 2 and the lower linear module 22, the transparent hopper 225 moves to the bottom of the closed testing tank 63, and the vertical cylinder 224 rises, pressing the transparent hopper 225 tightly against the bottom opening of the closed testing tank 63; the closed testing tank 63 is equipped with a heating device and an electronic nose. After heating to 50°C and maintaining it for 10 minutes, the electronic nose is used to detect the content of aldehydes, heterocyclic compounds, and alcohols inside the closed testing tank 63 to determine the quality of the rice.

[0085] Test completed: Under the combined action of the rotary worktable 21 of the rotary conveying module 2 and the lower linear module 22, the transparent hopper 225 moves to the transparent cover 11, the transparent cover 11 is opened, the rice sample is taken out, and the test is completed.
