[0021] The sample storage unit 300 includes a sample storage tray 310, a rotating tray 320, an inverting base 330, a sample storage tube 340, and a stepping motor 350. The stepping motor 350 and the sample storage tray 310 are fixedly mounted on one side of a transmission box 410.

[0023] Specifically, the liquid passing gear 111 is rotated by the flow of the supply liquid, thereby metering the amount of supply liquid, controlling the extension and retraction movement process of the moving rod 200, and avoiding the introduction of an excessive amount of vinegar liquid.

[0024] In this embodiment, the inversion base 330 has a V-shaped structure, and a rotation pin is provided on the surface of the inversion base 330, and the inversion base 330 is rotatably attached to the surface of the sample storage tray 310 via the rotation pin.

[0026] Specifically, when the rotating tray 320 drives the rotation of the inversion bases 330, the balls on the surface of each inversion base 330 move through the inside of the mounting block 361 until the inversion base 330 with the empty sample storage tube 340 moves to the mounting block 361, and then the putter 360 is used to push the inversion base 330 to deflect it, and the sample storage tube 340 is removed.

[0027] In this embodiment, the outside of the operating main rod 440 is provided with a spline rib, and the inside of the interrupted gear disc 442 is provided with a spline fitting hole that fits the operating main rod 440.

[0028] Specifically, a splined connection between the actuating main rod 440 and the interrupted gear disc 442 allows the actuating main rod 440 to slide and rotate synchronously relative to the interrupted gear disc 442 .

[0029] In this embodiment, a ball is provided at one end of the inversion base 330, and a C-shaped fitting groove that fits the ball is provided on the surface of the fitting block 361, the fitting block 361 and the ball are equidistant from the center of the circle of the rotating tray 320 and are in the same plane, clamping grooves are provided at both ends of the tube replacement clip 450, which are symmetrical with respect to the center origin of the circle of the operating main rod 440, for clamping the sample storage tube 340, a clamping pin 451 is fitted into the inside of the tube replacement clip 450, the clamping pin 451 has an electric putter structure, and the output end extends radially to face the inside of the clamping groove, and a notch groove is provided at the bottom end of the sample storage tray 310, and one of the clamping grooves is directly below the notch groove of the sample storage tray 310.

[0030] Specifically, the sample storage tube 340 is clamped using the tube exchange clip 450 and moved below the extrusion port 102 and abutted against the extrusion port 102, and thus the sample storage tube 340 is moved between the extrusion port 102 and the sample storage tray 310.

[0031] In this embodiment, a ring bevel gear is provided on the surface of the main gear disc 430, which is rotatably engaged with the output end of the driving motor 420. A plurality of meshing grooves 431 are provided on the surface of the main gear disc 430. The interrupted gear disc 442 slidably meshes with the surface of the meshing grooves 431. The meshing grooves 431 are inclined outwardly on the circumference of the main gear disc 430, and there is a gap between adjacent meshing grooves 431.

[0032] Specifically, the meshing groove 431 and the interrupted gear disc 442 mesh with each other, so that the interrupted gear disc 442 is driven to rotate during the rotation process of the main gear disc 430, and thereby the interrupted gear disc 442 and the operating main rod 440 rotate intermittently.

[0033] In this embodiment, an eccentric guide groove 432 is provided on one side of the main gear disc 430, and both sides of the eccentric guide groove 432 are unequally spaced from the center of the circle of the main gear disc 430. A rotating pin fixed to the inside of the transmission box 410 is provided on one end of the crank rod 460, and a guide pin is provided on the surface of the crank rod 460, which is slidably fitted into the inside of the eccentric guide groove 432.

[0034] Specifically, during the rotation of the main gear disc 430, the eccentric guide groove 432 meshes with and slides against the guide pin on the surface of the crank rod 460, causing the crank rod 460 to deflect in the up and down direction, and as a result, the crank rod 460 is joined to the guide ring bush 441, causing the operating main rod 440 and the tube replacement clip 450 to move up and down.

[0035] The working principle and use procedure of the present invention are as follows.

[0036] When using this detection device, each sample storage tube 340 is arranged in one-to-one correspondence inside the inverted base 330 on the surface of the sample storage tray 310, and the intermittent sampling time during vinegar fermentation is set, and automatic sampling is controlled by the controller to perform detection. During the vinegar brewing process, the rotating tray 320 drives the rotation of the inverted base 330 so that a certain inverted base 330 moves into the inside of the fitting block 361, and the fitting block 361 is pushed by the pusher 360, and the fitting block 361 moves so that the inverted base 330 rotates in the rotating tray. The sample storage tube 340 is deflected on the surface of the tray 320, and the sample storage tube 340 is tilted and deflected, and is taken out from the notch groove on the surface of the sample storage tray 310. The driving motor 420 drives the rotation of the main gear disk 430, and the rotation of the main gear disk 430 causes the meshing groove 431 to mesh with the interrupted gear disk 442 to transmit power, so that the interrupted gear disk 442 and the guide ring bush 441 are driven to perform a deflection operation as a whole, and the bottom end tube exchange clip 450 is deflected by 180°. The main gear disk 430 is then clamped. The guide pin on the surface of the crank rod 460 is rotated to abut against the inside of the eccentric guide groove 432, and the crank rod 460 is slidably driven so as to deflect in the vertical direction, and as a result, the end of the crank rod 460 is joined to the guide ring bush 441, so that the operating main rod 440 and the crank rod 460 slide in the vertical direction while being guided by the interrupted gear disc 442 and the sliding bush receiving part 411. In this way, the clamping pin 451 inside the tube exchange clip 450 actively extends, and the sample storage tube 340 that has been taken out is inserted into the tube exchange clip 450. The crank rod 460 is clamped, and the guide pin on the surface of the crank rod 460 abuts against the inside of the eccentric guide groove 432, and the crank rod 460 is slidably driven so as to be deflected in the vertical direction. In this way, the end of the crank rod 460 is joined to the guide ring bush 441, and the operating main rod 440 and the crank rod 460 move downward, and the sample storage tube 340 is detached from the inversion base 330 and rotated 180° together with the tube exchange clip 450 to just below the extrusion port 102, and the guide pin on the surface of the crank rod 460 abuts against the inside of the eccentric guide groove 432,The crank rod 460 is slidably driven so as to deflect in the vertical direction, and the end of the crank rod 460 is connected to the guide ring bush 441, so that the operating main rod 440 and the crank rod 460 are guided by the interrupted gear disc 442 and the sliding bush receiving part 411 and move upward to be connected to the extrusion port 102. When the material is supplied, the vinegar liquid in the brewing tank is introduced from one end of the suction port 101 by the reciprocating drive of the moving rod 200 and is injected into the inside of the sample storage tube 340, thus completing the collection of the vinegar liquid for that period.

[0037] The above operations are repeated until all vinegar fermentation stages are completed, and the fermentation samples of each stage are stored in different sample storage tubes 340 and sent to a laboratory for detection of moisture, acidity, glycoamylase activity, yeast cell count, germination rate, reducing sugar and alcohol content, etc., so as to grasp various changes during production and take measures to adjust the process and improve the yield and quality of the finished product.
