The second motor 507 drives the second shaft 508 to rotate forward, driving the horizontal plate 504 to move upward, and the slide bar 501 slides upward along the linear groove 401, thereby driving the hoop 503 and the liquid storage cylinder 601 to move upward until the support ring 603 fits the bottom of the fixing ring 304; S2, the food to be tested is added into the conical cylinder 301 through the feeding hopper 305, the rotating shaft 310 is driven to rotate by the motor 309, the cutting knife 311 cuts and crushes the food, and then the crushed food is transported downward by the spiral blade 312, and finally the conical grinding disc 313 rotates and cooperates with the horn cover 303 to grind the crushed food; S3. At the same time, water is injected into the annular cover 306 through the water injection pipe 307. The water flows through the through hole 308 into the interior of the conical cylinder 301 and flows downward to rinse the interior of the grinding assembly 300. At the same time, the ground food follows the water flow into the interior of the liquid storage cylinder 601. The U-shaped stirring rod 314 follows the rotating shaft 1 310 to rotate inside the liquid storage cylinder 601, stirring the ground food so that the ground food and water are evenly mixed, and filtered through the filter cartridge 602 to prevent residue from entering the interior of the liquid storage cylinder 601. S4, the second motor 507 drives the second shaft 508 to rotate in the opposite direction, driving the sliding assembly 500 and the liquid storage assembly 600 to move downward, so that the butt joint 702 is sleeved on the outside of the drain pipe 604, the push rod 704 is inserted into the inside of the drain pipe 604, and the push rod 704 pushes up the sealing cone 609, so that the mixed solution of food and water in the liquid storage cylinder 601 passes through the collar 606 and is injected into the inside of the receiving cylinder 804; S5, the motor 2 507 is used to drive the second shaft 508 to rotate forward, so that the drain pipe 604 is separated from the butt joint 702, and the sealing cone 609 moves downward under the elastic action of the spring 1 610 to seal the collar 606; the motor 2 507 is used to drive the second shaft 508 to rotate reversely, so that the drain pipe 604 is connected to the butt joint 702 again; S6. Through S5, the second shaft 508 first rotates forward and then rotates reversely, driving the turntable 907 to rotate back and forth, thereby driving the slide post 908 to reciprocate in a circular motion. The slide post 908 pushes the slide plate 904 to slide back and forth along the guide groove 1 902 and the guide groove 2 903, so that the L-shaped bracket 905 and the ratchet assembly move back and forth. When the L-shaped bracket 905 moves from front to back, the push tooth 914 abuts against the ring gear 805, and the push tooth 914 is blocked by the baffle plate 2 912, and the boss 915 is The baffle 911 blocks the pushing tooth 914 and the rotating wheel 913, so that they cannot deflect, and the pushing tooth 914 pushes the ring gear 805 to rotate, driving the mounting plate 801 to rotate, so that the next accommodating cylinder 804 is transferred to the bottom of the docking tube 702; when the L-shaped bracket 905 moves from back to front, the pushing tooth 914 is blocked by the ring gear 805, so that the pushing tooth 914 and the rotating wheel 913 are deflected, and the boss 915 squeezes the spring 2 916 to prevent the pushing tooth 914 from pushing the ring gear 805 to rotate.
