Description

Technical Field

[0001] The invention relates to the field of sampling facilities, and in particular to a sample collection device for dairy product testing. Background Art

[0002] Dairy products are processed products made from fresh cow's milk or goat's milk and their products as the main raw materials. Dairy products are rich in protein, calcium, vitamins and other nutrients, especially calcium, which is one of the best sources of calcium in the human diet. Eating dairy products in moderation can supplement the nutrients and energy needed by the human body. In the process of dairy processing, in order to ensure product quality, it is often necessary to sample the dairy products stored in the storage barrels, and then test the sampled samples to confirm whether they are qualified.

[0003] In the actual sampling process, in order to improve the comprehensiveness of sampling, it is often necessary to sample dairy products at different depths in the storage barrel. However, since dairy products are non-transparent liquids, it is difficult to distinguish the specific depth of the sampling tube in the storage barrel when the sampling tube is inserted into the storage barrel for sampling, resulting in the phenomenon that the sampling depth does not meet the standard, which seriously affects the sampling accuracy.

[0014] 2. By pulling the No. 2 pull ring, the fixed rod pushed by the fixed spring can be driven out of the adjustment hole, so that the adjustment sleeve can slide on the carrier without the restriction of the fixed rod, thereby driving the sampling tube to move and adjust the position of the sampling tube to adapt to the purpose of sampling dairy products at the center or edge of the storage barrel, thereby ensuring the flexibility of sampling.

[0015] 3. When the sampling tube is pushed down to extend into the specified depth in the dairy product, the positioning frame will move down synchronously. At this time, the locking teeth are pushed out of the slot by the positioning frame using their own inclined surfaces, and the tightening spring contracts and deforms. When the pushing of the sampling tube stops, the tightening spring will restore its deformation to push the top seat so that the locking teeth re-engage in the slot on the positioning frame to restrict the sampling tube, so that the sampling tube can be suspended in the dairy product by itself without anyone grabbing it, thereby avoiding the need to grab the sampling tube all the time during the sampling process, which effectively facilitates use.

[0021] A pull ring 25 is fixedly installed on the upper end of the sampling rod 24, and a sliding sleeve 5 is fixedly installed on the upper edge of the rear end of the sampling tube 6. The pull ring 25 facilitates the pulling of the sampling rod 24. The sliding sleeve 5 is slidably installed on the outer surface of the pushing frame 4.

[0024] The locking member includes a rod seat 16 installed on the side of the groove guide seat 11, and two pull rods 15 are slidably installed on the side of the rod seat 16. One end of the two pull rods 15 is fixedly installed with a top seat 12. The rod seat 16 plays a role in bearing the pull rods 15. A linear array on one side of the top seat 12 extends a plurality of latch teeth 32. The pull rod 15 plays a role in guiding and pulling the top seat 12. The upper and lower ends of the latch teeth 32 are both inclined. The linear array on the side of the positioning frame 3 is provided with a plurality of slots 1 9, the latching teeth 32 are fitted into the inside of the slot 19.

The end of the connecting seat 14 is penetrated and inlaid with a No. 2 connecting shaft 34. The pushing frame 13 The end portion is rotatably mounted on the outer surface of the No. 2 connecting shaft 34. The No. 1 connecting shaft 33 and the No. 2 connecting shaft 34 both serve to facilitate the connection of the pushing frame 13. When pushing the sampling tube 6, the sampling tube 6 can be pushed directly, or the pressing seat 10 can be pressed first to drive the pushing frame 13 to move, so as to push the connecting seat 14, and then push the top seat 12 to separate the latch tooth 32 and the latch groove 19, so that the sampling tube 6 will not be subject to the resistance of the latch tooth 32 when being pushed, so that the sampling tube 6 can be pushed more labor-saving.

[0027] When in use, the carrier 1 is placed on the storage barrel 35. At this time, the limiting ear 2 is engaged with the barrel edge of the storage barrel 35 for limiting, so that the positioning head 7 can be close to the surface of the storage barrel 35. Then, the second pull ring 31 is pulled to drive the fixing rod 28 pushed by the fixing spring 29 to disengage from the adjustment hole 26, so that the adjustment sleeve 21 can slide on the carrier 1 without the restriction of the fixing rod 28, thereby driving the sampling tube 6 to move, so as to adjust the position of the sampling tube 6 to adapt to the sampling of dairy products at the center or edge of the storage barrel 35. Then, the sampling tube 6 is pushed to move downward. At this time, the positioning head 7 on the positioning frame 3 is on the surface of the storage barrel 35. The positioning head 7 moves synchronously, so as to accurately understand the position of the sampling tube 6 in the dairy product by observing the position of the positioning head 7 in the storage barrel 35. During the downward movement of the positioning frame 3, the latching tooth 32 will be pushed by the positioning frame 3 by its own inclined surface and disengage from the slot 19. At the same time, the tightening spring 17 contracts and deforms. When the sampling tube 6 moves down to the specified sampling depth, the tightening spring 17 will restore its deformation to push the top seat 12 so that the latching tooth 32 is re-engaged in the slot 19 on the positioning frame 3 to restrict the sampling tube 6. Then, the sampling rod 24 can be pulled to make the piston 23 slide in the sampling tube 6 to suck the dairy product at the depth into the sampling tube 6 to complete the sampling.
