[0039] For details, please refer to Figure 1 , Figure 7 and Figure 8 When monitoring quick-frozen vegetables, the following steps are included:
[0040] Step 1, placing the sample; placing the tuberous vegetables in the clamping box 2 and clamping them;
[0041] Step 2, obtaining a columnar sample 301; starting the first lifting mechanism 11 and the first motor 13, the drill tube 9 rotates downward to drill into the vegetable body 3, forming an annular groove in the vegetable body 3, and part of the vegetable body 3 enters the drill tube 9 to form a columnar sample 301, and when the sample length reaches the set sampling length, the first lifting mechanism 11 is closed;
[0042] Step 3, cutting the columnar sample 301; starting the electromagnetic ring 18, the electromagnetic ring 18 repels the sliding ring 15, the sliding ring 15 drives the flexible blade 14 to move downward, the flexible blade 14 extends from the extension port 9011 in the drill tube 9, the flexible blade 14 abuts against the circumferential side wall of the columnar sample 301, and as the drill tube 9 rotates, the flexible blade 14 rotates and cuts the columnar sample 301. After the cutting is completed, the drill tube 9 is closed;
[0043] Step 4, transfer the columnar sample 301; start the first lifting mechanism 11, close the first lifting mechanism 11 after the drill tube 9 is separated from the vegetable body 3, start the transfer mechanism 5, so that the drill tube 9 moves to the top of the detection tube 601, and then open the first lifting mechanism 11 again, so that the drill tube 9 is inserted into the door of the detection tube 601, and then close the first lifting mechanism 11, start the electromagnetic ring 18, and the sliding ring 15 drives the flexible blade 14 to be stored in the inner wall of the drill tube 9, and periodically close and start the first lifting mechanism 11, so that the columnar sample 301 is discharged into the detection tube 601 under the action of gravity and inertia;
[0044] Step 5, crushing the sample; the carrier plate 6 drives the detection tube 601 loaded with the columnar sample 301 to move to the bottom of the crushing mechanism 7, and the crushing mechanism 7 squeezes and crushes the columnar sample 301 in the detection tube 601;
[0045] It should be noted that each detection cylinder 601 is filled with a pre-added solvent to facilitate mixing of the crushed sample residue with the solvent for subsequent spectral detection;
[0046] For details, please refer to Fig.11 and Fig.12 The detection tube 601 is sleeved with a grinding filter cover 602, and the crushing mechanism 7 includes a grinding head 701 matched with the grinding filter cover 602, and the grinding head 701 is fixedly connected with a lifting screw 702, and the lifting screw 702 is threadedly connected with a support frame, and a prism shaft 703 is slidably inserted in the lifting screw 702, and the upper end of the prism shaft 703 is fixedly connected with a rotating motor 704 fixedly connected with the support frame; the rotating motor 704 drives the prism shaft 703 to rotate, and the prism shaft 703 drives the lifting screw 702 threadedly connected with the support frame to rotate up and down, and the lifting screw 702 drives the grinding head 701 to rotate up and down in the grinding filter cover 602, grinds and crushes the columnar sample 301 and squeezes out juice, and the juice falls into the solvent below through the filter hole;
[0047] Step six, spectral detection; the carrier plate 6 drives the crushed sample mixture to rotate to the position of the spectrum detector 8, and the spectrum detector 8 performs spectral detection on the sample mixture.
[0048] Please note that Fig. 9 and Fig.10 The spectrum detector 8 is provided with a light source generator 801 and a receiver 802 which are relatively arranged on both sides of the detection cylinder 601, so as to facilitate the detection of multiple detection cylinders 601 rotating in a circle one by one, thereby improving the detection efficiency.
[0049] Compared with the traditional quick-frozen vegetable detection method, the present invention uses a drill barrel 9 that rotates up and down and a flexible blade 14 that is housed in the drill barrel 9 and can be extended. When sampling tuber vegetables, the drill barrel 9 is used to drill into the hard quick-frozen vegetables and the extended flexible blade 14 is used to cut the columnar sample 301 on the inside of the drill barrel 9 to achieve automatic sampling; at the same time, by cooperating with the first lifting mechanism 11, the transfer mechanism 5 and the rotating supporting plate 6, multi-batch automatic sampling and layout are achieved. In addition, the sampling depth is controlled by the first lifting mechanism 11 to meet the multi-depth detection requirements, and the crushing mechanism 7 and the spectrometer 8 arranged on the outside of the supporting plate 6 are used to achieve batch automatic detection to meet the multi-batch and multi-depth detection requirements.
[0050] See also Figure 6 The drill tube 9 is a hollow cylindrical structure with an opening at the lower end. An annular blade portion is provided at the opening at the lower end of the drill tube 9. A guide groove 901 for accommodating the flexible blade 14 is provided in the inner wall of the drill tube 9. The guide groove 901 is J-shaped.
[0051] In this embodiment, the flexible blade 14 is made of a flexible metal material or a flexible plastic material, and a blade portion is provided at the lower end of the flexible blade 14 .
[0052] Specifically, it is convenient to realize the storage and extension of the flexible blade 14.
[0053] See also Figure 4 and Figure 5 The guide tube 16 is an annular tube and is fixedly connected to the drill tube 9 by bolts. An electromagnetic coil is nested in the electromagnetic ring 18, and the electromagnetic coil is connected to an electromagnetic driver installed on the lifting frame 10. The limit spring 17 is arranged on the inner side of the flexible blade 14.
[0054] Specifically, the electromagnetic driver applies currents in different directions to the electromagnetic coil to achieve repulsion and attraction of the sliding ring 15, and the extension and storage of the flexible blade 14. At the same time, the limit spring 17 makes the sliding ring 15 at the highest point when not affected by external force, that is, the flexible blade 14 remains stored in the drill barrel 9.
[0055] Second implementation method:
[0056] Figure 13-16A sample detection device for quick-frozen vegetables is shown. Based on the first embodiment, a chuck 19 is nested in a drill tube 9 and slidably abuts against the inner wall thereof. A lifting rod 20 extending to the top of the drill tube 9 is fixedly connected to the upper end of the chuck 19. The lifting rod 20 is connected to a second lifting mechanism 21. The second lifting mechanism 21 drives the chuck 19 to move up and down in the inner cavity of the drill tube 9 through the lifting rod 20. Cards 1901 distributed in a circle are provided on the lower end surface of the chuck 19. When the cards 1901 are inserted into the columnar sample The top of the vegetable 301 is fixedly connected to the top of the vegetable 301, so that the columnar sample 301, after being separated from the vegetable body 3, remains stationary when the drill tube 9 rotates; the chuck 19 is threadedly connected with a clamping screw 22 extending to the top of the drill tube 9, and the clamping screw 22 is slidably connected with a plug-in column 23 clamped thereto, and the plug-in column 23 is connected to a second motor 24 fixedly connected to the lifting frame 10, and the second motor 24 drives the clamping screw 22 threadedly connected to the chuck 19 to rotate through the plug-in column 23, thereby realizing the up and down rotation of the clamping screw 22.
[0057] For details, please refer to Figure 8 and Fig.14 In the initial state, the chuck 19 is located at the lower end opening position of the drill tube 9 and the lower end of the clamping screw 22 is flush with the lower end of the chuck 19. As the drill tube 9 drills into the vegetable body 3, the second lifting mechanism 21 drives the chuck 19 to move upward through the lifting rod 20 and always keeps the chuck 19 in contact with the top of the columnar sample 301, so that the card 1901 is inserted into the top of the columnar sample 301. At the same time, the second motor 24 drives the clamping screw 22 to rotate downward and insert it into the columnar sample 301 until the sampling of the columnar sample 301 is completed. At this time, the chuck 19 and the clamping screw 22 cooperate to lift and limit the columnar sample 301 in the drill tube 9, so as to achieve stable clamping of the columnar sample 301 that is separated from the vegetable body 3 in the drill tube 9;
[0058] It is specifically applied in the sampling step of step 2 and the transfer step of step 4. In step 2, columnar samples 301 of different depths can be sampled at one time. In step 4, when the columnar sample 301 is transferred to the detection cylinder 601, it can be segmented and cut. The segmented cutting process includes the following sub-steps:
[0059] Sub-step 1: stowing the flexible blade 14; activating the electromagnetic ring 18 so that the flexible blade 14 is stowed in the drill tube 9;
[0060] Sub-step 2: the columnar sample 301 is extended to the length to be cut off; the second motor 24 and the second lifting mechanism 21 are started at the same time, the clamping screw 22 rotates upward and the chuck 19 pushes the columnar sample 301 downward until the height of the lower end of the clamping screw 22 is higher than the height to be cut off of the columnar sample 301;
[0061] Sub-step three, cutting the extended section of the columnar sample 301; starting the electromagnetic ring 18 and the first motor 13, so that the flexible blade 14 extends again, the first motor 13 drives the drill tube 9 and the flexible blade 14 to rotate, and the extended section of the columnar sample 301 is cut off and falls into one of the detection tubes 601 on the carrier plate 6;
[0062] Sub-step four, repeating sub-step one to sub-step three to achieve segmented cutting and blanking of the columnar sample 301.
[0063] Specifically, in the scheme of Example 1, samples at different depths need to be sampled multiple times. In this embodiment, one sampling and multiple truncation and cutting are adopted to improve the overall sampling efficiency.
[0064] See also Fig.16 The chuck 19 is a disc-shaped structure, and the card 1901 is a square blade with a pointed inner side and an isosceles trapezoidal cross section.
[0065] Specifically, through the card 1901 in the form of a square blade, when the chuck 19 abuts against the columnar sample 301, the card 1901 is inserted into the top of the columnar sample 301, and the card 1901 is tightly inserted into the columnar sample 301, so that the drill tube 9 and the flexible blade 14 cannot drive the columnar sample 301 to rotate when rotating, thereby ensuring the truncation and cutting efficiency of the columnar sample 301.
[0066] In this embodiment, both the first lifting mechanism 11 and the second lifting mechanism 21 are hydraulic telescopic cylinders or vertical screw modules, and the transfer mechanism 5 is a horizontal screw module.
[0067] Specifically, it is convenient to make the vertical and horizontal movements of the drill tube 9 possible, so as to realize multi-point and multi-depth sampling.
[0068] See also Fig.15 The plug-in column 23 is a prismatic rod with a regular polygonal cross section. The clamping screw 22 is provided with a prismatic groove with an upper end opening. The plug-in column 23 is inserted into the prismatic groove and slides against the inner wall thereof. A through hole is provided at the upper end of the drill tube 9 for the clamping screw 22 to pass through. The inner diameter of the through hole is greater than the lateral width of the clamping screw 22.
[0069] Specifically, the chuck 19 can drive the clamping screw 22 to move up and down without affecting the power transmission between the clamping screw 22 and the plug-in column 23 .
[0070] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
