[0044] A fixing plate 53, wherein the fixing plate 53 is fixedly installed inside the detection box 1, and an inclined portion 56 is provided at the bottom end of the fixing plate 53;

[0045] The baffle 55 is hingedly disposed at the bottom end of the material tray 54 and a torsion spring is disposed at the hinged position. A roller 57 is disposed at one end of the baffle 55, and the roller 57 is slidably matched with the fixed plate 53 at one side of the inclined portion 56;

[0046] See also Figure 2-Figure 3 In one embodiment, the linkage group 3 includes:

[0047] A driving shaft 31, wherein the driving shaft 31 is rotatably connected to the inside of the detection box 1, and an incomplete gear 32 and an active dial 34 are fixedly installed in the middle of the driving shaft 31;

[0048] An adjusting gear 33, wherein the adjusting gear 33 is fixedly connected to the connecting shaft 41, and the adjusting gear 33 is meshed with the incomplete gear 32 for transmission;

[0049] The food sample to be tested is put into the test box 1 from the feed port 12, and the upper partition 42 can block the food sample. After the food sample is put in, the entire test box 1 is closed, and the driving shaft 31 inside the test box 1 is controlled to rotate by the control module 2, and the driving shaft 31 then drives the incomplete gear 32 to rotate. Due to the meshing transmission between the incomplete gear 32 and the adjusting gear 33, the connecting shaft 41 can be further driven to rotate, and the connecting shaft 41 then drives the upper partition 42 and the lower partition 43 to rotate at the same time. During the rotation of the upper partition 42 and the lower partition 43, due to The radial lengths of the upper partition 42 and the lower partition 43 are different and they are symmetrically arranged about one of the planes. When the short diameter end of the upper partition 42 is close to the cylindrical barrel 44, the long diameter end of the lower partition 43 is close to the cylindrical barrel 44. At this time, the lower partition 43 acts as a barrier. When the long diameter end of the upper partition 42 is close to the cylindrical barrel 44, the short diameter end of the lower partition 43 is close to the cylindrical barrel 44. At this time, the upper partition 42 acts as a barrier, and the food sample in the cylindrical barrel 44 formed by the upper partition 42, the lower partition 43 and the inner wall of the detection box 1 enters the material tray 54 in the middle of the mounting plate 52.

[0050] A driven sheave 35, wherein the driven sheave 35 is fixedly connected to the top end of the mounting shaft 51, and the driving dial 34 is in transmission connection with the driven sheave 35;

[0051] The control module 2 is fixedly installed outside the detection box 1, and the output end of the control module 2 is connected to the input end of the driving shaft 31 through PLC control;

[0052] As the driving shaft 31 drives the incomplete gear 32 to rotate, the active dial 34 also rotates accordingly. Due to the transmission connection between the active dial 34 and the driven groove wheel 35, the mounting shaft 51 can be further driven to rotate, and then the mounting plate 52 can rotate with the mounting shaft 51. As the mounting plate 52 rotates, the material tray 54 in the middle thereof rotates accordingly. As the material tray 54 rotates, the roller 57 at one end of the baffle 55 can make an arc motion along one side of the fixed plate 53 until the baffle 55 rotates with the material tray 54 to the inclined portion 56 of the fixed plate 53. Through the action of the torsion spring, the baffle 55 can rotate around the bottom end of the material tray 54. At this time, a sliding fit is formed between the roller 57 and the inclined portion 56. As the baffle 55 rotates around the bottom end of the material tray 54, the food sample inside the material tray 54 can enter the detection end 13 of the detection box 1 from the bottom, and finally complete a single detection of the food sample.

[0053] After the detection of one of the food samples is completed, as the second movement cycle of the drive shaft 31 begins, the food sample at the position of the feed port 12 enters the next material tray 54 under the rotation cooperation of the upper partition 42 and the lower partition 43, and as the transmission cooperation of the linkage group 3, the installation shaft 51 can be rotated, and the installation shaft 51 further drives the multiple material trays 54 to rotate. When one of the material trays 54 that has completed the feeding detection begins to move away from the inclined portion 56 of the fixed plate 53, the baffle 55 at the bottom of the material tray 54 is moved away from the inclined portion 56 of the fixed plate 53 by the torsion spring. The lower part forms a closed state with the material tray 54 again, and the other material tray 54 gradually approaches the inclined portion 56, and under the sliding cooperation between the roller 57 and the inclined portion 56, the baffle 55 at the bottom of the material tray 54 rotates around the bottom of the material tray 54 through the action of the torsion spring, and finally the food sample inside the material tray 54 enters the detection end 13 of the detection box 1 from the bottom again, and the food sample is subjected to secondary detection. By rotating the driving shaft 31 for multiple cycles, multiple detections of the food sample can be realized, and finally multiple detection data can be read.

[0054] See also Figure 1 In addition to the above technical solution, the present invention also provides another embodiment. The difference between this embodiment and the above embodiment is that: a caster 11 is provided at one end of the outside of the detection box 1 located on the ground, and the caster 11 is symmetrically arranged about the detection box 1, which can make the detection box 1 more convenient and labor-saving during movement.

[0055] The working principle of the present invention is:

[0056] In this embodiment, the food sample to be tested is put into the test box 1 from the feed port 12, and the food sample can be blocked by the upper partition 42. After the food sample is put in, the entire test box 1 is closed, and the drive shaft 31 inside the test box 1 is controlled to rotate by the control module 2. The drive shaft 31 then drives the incomplete gear 32 to rotate. Due to the meshing transmission between the incomplete gear 32 and the adjustment gear 33, the connecting shaft 41 can be further driven to rotate, and the connecting shaft 41 then drives the upper partition 42 and the lower partition 43 to rotate at the same time. During the rotation of the upper partition 42 and the lower partition 43, since the radial lengths of the upper partition 42 and the lower partition 43 are different and are symmetrically arranged about one of the planes, when the short diameter end of the upper partition 42 is close to the position of the cylindrical barrel 44, The long diameter end of the lower partition 43 is close to the cylindrical barrel 44, and the lower partition 43 acts as a block. When the long diameter end of the upper partition 42 is close to the cylindrical barrel 44, the short diameter end of the lower partition 43 is close to the cylindrical barrel 44. At this time, the upper partition 42 acts as a block, and the food sample in the cylindrical barrel 44 formed by the upper partition 42, the lower partition 43 and the inner wall of the detection box 1 enters the material tray 54 in the middle of the mounting plate 52. As the driving shaft 31 drives the incomplete gear 32 to rotate, the active dial 34 also rotates accordingly. Due to the transmission connection between the active dial 34 and the driven groove wheel 35, the mounting shaft 51 can be further driven to rotate, thereby causing the mounting plate 52 to rotate with the mounting shaft 51. As the mounting plate 52 rotates, the material tray 54 in the middle rotates accordingly. , and as the material tray 54 rotates, the roller 57 at one end of the baffle 55 can make an arc movement along one side of the fixed plate 53, until the baffle 55 rotates with the material tray 54 to the inclined portion 56 of the fixed plate 53, and the baffle 55 can rotate around the bottom end of the material tray 54 through the action of the torsion spring. At this time, a sliding fit is formed between the roller 57 and the inclined portion 56, and as the baffle 55 rotates around the bottom end of the material tray 54, the food sample inside the material tray 54 can enter the detection end 13 of the detection box 1 from the bottom, and finally complete a detection of the food sample. After the detection of one of the food samples is completed, as the second movement cycle of the drive shaft 31 begins, the food sample at the position of the feed port 12 is rotated in the rotation fit of the upper partition 42 and the lower partition 43 The mounting shaft 51 rotates and the mounting shaft 51 drives the plurality of material trays 54 to rotate. When one of the material trays 54 that has completed the feeding detection begins to move away from the inclined portion 56 of the fixing plate 53, the baffle plate 55 at the bottom of the material tray 54 forms a closed state with the material tray 54 again under the action of the torsion spring. The other material tray 54 that gradually approaches the inclined portion 56, under the sliding cooperation of the roller 57 and the inclined portion 56, the baffle plate 55 at the bottom of the material tray 54 rotates around the bottom of the material tray 54 through the action of the torsion spring, and finally the food sample inside the material tray 54 enters the detection end 13 of the detection box 1 from the bottom again for secondary detection of the food sample.By rotating the drive shaft 31 for multiple cycles, multiple tests of food samples can be performed, and multiple test data can be read.
