The rotating ring 8 plays a regulating role. By rotating the rotating ring 8 and cooperating with the connecting rod 9, the blocking plate 7 is driven to move along the direction of the slide groove 6, so as to facilitate the control of the opening and closing of the partition hole 5 through the blocking plate 7, and control the raw milk above the partition plate 4 to flow into the lower part through the partition hole 5. The end of the blocking plate 7 is provided with a rubber protrusion 24, and the rubber protrusion 24 is movably clamped in the partition hole 5. When the blocking plate 7 moves to the position of the partition hole 5, the rubber protrusion 24 is clamped in the partition hole 5 to prevent the raw milk from leaking from the partition hole 5.

[0031] The sampling cylinder 10 is a cylindrical structure with upper and lower openings. The top of the sampling cylinder 10 is clamped on the inner wall of the rotating ring 8. The bottom of the sampling cylinder 10 is provided with a flip cover 11. The sampling cylinder 10 is divided into several containers of different volumes, which is convenient for operators to sort fresh milk through the sampling cylinder 10;

[0032] The fixing assembly 12 is arranged on the bottom surface of the rotating ring 8, and the fixing assembly 12 is connected to the sampling tube 10. The fixing assembly 12 includes:

[0033] The fixing sleeve 13 is fixedly arranged at the bottom surface of the rotating ring at the top end thereof, and the sampling barrel 10 is movably inserted in the fixing sleeve 13. A concave groove 14 is provided through the side wall of the sorting barrel 2, and the concave groove 14 is located below the partition plate 4. The fixing sleeve 13 plays a positioning role, which is convenient for movably inserting the top end of the sampling barrel 10 in the fixing sleeve 13. A limiting rod 18 is fixedly arranged at the bottom end of the fixing sleeve 13. A limiting groove 19 is provided on the side wall of the sampling barrel 10. The limiting rod 18 is movably inserted in the limiting groove 19, which is convenient for limiting the limiting rod 18 so that the sampling barrel 10 can only be fixed. The fixing sleeve 13 is installed in the same position, a fixing ring 20 is provided on the inner wall of the fixing sleeve 13, a breathable sponge 21 is provided on the bottom surface of the fixing ring 20, the top of the sampling tube 10 movably contacts the breathable sponge 21, a breathable plate 22 is fixedly provided in the sampling tube 10, and a funnel 23 is provided on the breathable plate 22, the funnel 23 is matched with the partition hole 5, and a breathable hole is provided through the fixing sleeve 13, and the fresh milk can be poured into the sampling tube 10 through the funnel 23, and the gas in the sampling tube 10 can be easily leaked out of the fixing sleeve 13 by the breathable effect of the breathable plate 22 and the breathable sponge 21, so that the fresh milk can enter the sampling tube 10;

[0034] A fixing rod 15, one end of which is screwed to the outer wall of the fixing sleeve 13 by a rebound shaft, and the other end of which is movably inserted in the concave groove 14. The fixing rod 15 plays an adjusting role. By moving the fixing rod 15, the fixing rod 15 slides in the concave groove 14, thereby driving the fixing sleeve 13 to rotate;

[0035] The latch 16 is a plurality of latches 16, which are movably inserted into the side wall of the fixing sleeve 13 by means of a spring 17, and the two ends of the spring 17 are respectively connected to the latch 16 and the fixing sleeve 13, and the end of the latch 16 is movably inserted into the groove body of the side wall of the sampling barrel 10. When the sampling barrel 10 is inserted into the fixing sleeve 13, the elastic force of the spring 17 causes the end of the latch 16 to be inserted into the groove body of the side wall of the sampling barrel 10, so that the sampling barrel 10 is conveniently fixed in the fixing sleeve 13.

[0036] When using the utility model, the operator selects a sampling tube 10 of a suitable volume, and movably inserts the sampling tube 10 into the fixing sleeve 13, so that the bottom end of the limiting rod 18 slides in the limiting groove 19, so that the top end of the sampling tube 10 abuts against the breathable sponge 21, and the elastic force of the spring 17 makes the latch 16 movably inserted into the groove body on the side wall of the sampling tube 10, so that the sampling tube 10 is fixed in the fixing sleeve 13, and then the raw milk is poured into the sorting tube 2, so that the raw milk is stored above the partition plate 4, the piston push rod 3 is installed at the top of the sorting tube 2, and then the fixing rod 15 is pulled to make the fixing rod 15 slide in the concave groove 14, and when the fixing rod 15 moves to the appropriate position, the action of the rebound rotating shaft makes the fixing rod 15 movably clamped in the vertical groove of the concave groove 14, and the fixing rod 15 drives the fixing sleeve 13 to rotate, and the fixing sleeve 13 drives the rotating ring 8 to rotate, and the rotating ring 8 rotates. The movable ring 8 drives the connecting rod 9 to rotate, and the connecting rod 9 drives the blocking plate 7 to move along the direction of the slide groove 6, so that the blocking plate 7 drives the rubber protrusion 24 to disengage from the partition hole 5, so that the raw milk above the partition plate 4 flows into the funnel 23 through the partition hole 5, and then flows into the sampling tube 10 from the funnel 23. At the same time, the operator can press the piston push rod 3 downward to increase the speed of the raw milk flowing into the funnel 23. Since the sorting tube 2 and the sampling tube 10 are both supported by transparent materials, the operator observes the liquid level of the raw milk in the sampling tube 10 until the liquid level of the raw milk reaches the bottom surface of the air permeable plate 22, and rotates the fixed rod 15 so that the rubber protrusion 24 blocks the partition hole 5. Finally, the operator places the detection container at the bottom end of the sampling tube 10, opens the flip cover 11, and pours the raw milk in the sampling tube 10 into the container, which is convenient for the operator to pour the same volume of raw milk into multiple containers in sequence.

[0037] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0038] 1. A sampling cylinder 10 is provided, and the sampling cylinder 10 is mounted on the bottom surface of the partition plate 4 by using a fixing assembly 12, so that the sampling cylinder 10 can be loaded with the same volume of fresh milk multiple times, and the operator can sort the fresh milk into multiple containers;

[0039] 2. Set up a fixing assembly 12, use the latch 16 to fix the sampling tube 10 in the fixing sleeve 13, and use the fixing rod 15 to drive the fixing sleeve 13 to rotate, thereby controlling the movement of the blocking plate 7, so that the operator can control the opening and closing of the partition hole 5.
