Description

Technical Field

[0001] The utility model relates to a sampler for milking, in particular to a clamp for the milk sampler. Background Art

[0002] Cows like to lie on the ground to ruminate and rest. The udders of cows that touch the ground (especially when the ground is dirty) are easily contaminated with a large number of bacteria. There is a milk duct from the nipple to the inside of the udder. Bacteria can easily enter the milk duct and grow and multiply there. Therefore, the first three handfuls of milk (i.e. three handfuls of milk) have a high bacterial content. If they are not discarded, the number of bacteria in the milk will be high, affecting the quality of the raw milk. Therefore, the three handfuls of milk should be discarded. When milking, you cannot squeeze the three handfuls of milk on the ground at will, but use a special container to collect it. First, avoid waste milk from polluting the ground environment and causing pathogenic microorganisms to spread infection. Second, squeeze it in a special container to facilitate observation of whether there are clots, flocs or watery milk in the milk, so as to detect clinical mastitis in time, provide timely treatment and prevent mastitis milk from mixing into normal milk.

[0003] At present, there are two main methods of milking: manual milking and using a breast pump. For manual milking, before milking, prepare a hot towel and warm water, apply the hot towel to the breasts to help the breasts to be unobstructed and prepare for milking, then wash your hands, sit or stand comfortably, place the container close to the cow's udder, put the thumb above the nipple, the index finger below the nipple, and the other fingers to hold the udder, and use the thumb and index finger to gently squeeze toward the chest wall, while keeping the fingers fixed, repeat this action until the milk flows out. This method of milking is not only time-consuming and laborious, but also very likely to contaminate the milk inside the milk pipe. When using a breast pump to milk, first wash your hands and the cow's udder, use warm water to soften and massage the cow's udder, then place the funnel of the breast pump on the base of the milk pool, keep it in a good closed state, and press the breast pump to suck out the milk. This milking method is easy to hurt the cow's nipple and make the cow feel pain. Summary of the invention

After milking, the cow's teat leaves between the silicone plate 3 and the corresponding impeller 2, the second spring 11.2 is reset, and the silicone plate 3 moves toward the impeller shaft 4. When the second stopper 13.2 contacts the second partition plate 10.2, the silicone plate 3 stops moving and reaches a fully reset state.

[0032] During milking, since the nipples of different cows are of different sizes, in order to dynamically change the distance between the silica gel plate 3 and the impeller 2 during milking, it is convenient to milk without causing pain to the cows. Fig.10 The utility model changes the spacing between the silica gel plate 3 and the corresponding impeller 2 by fine-tuning the position of the impeller 2. Specifically, a skeleton is provided on the frame 1, and the impeller shaft 4 passes through the skeleton. Adjustment holes 15 are provided on the skeleton corresponding to the two impellers 2, and the third spring support 12.3 passes through the adjustment hole 15.

The other end of the third spring support 12.3 is provided with a third stopper 13.3, and the third stopper 13.3 is located in the adjustment hole 15. One end of the third spring 11.3 is connected to the impeller 2, and the other end of the third spring 11.3 is connected to the skeleton. When the cow's nipple is large, the corresponding impeller 2 is squeezed to move the impeller 2 toward the impeller shaft 4, and the third spring 11.3 is compressed at this time. After milking, the cow's teat leaves between the silicone plate 3 and the corresponding impeller 2, the third spring 11.3 is reset, and the impeller 2 moves toward the silicone plate 3. When the third stopper 13.3 contacts the frame, the impeller 2 stops moving and reaches a fully reset state.

[0033] When the utility model adjusts the distance between the silica gel plate 3 and the impeller 2, any one of the three schemes of fine-tuning the position of the impeller shaft 4, fine-tuning the position of the silica gel plate 3, or fine-tuning the position of the impeller 2 can be adopted. A combination of any two of the three schemes can also be adopted. A combination of the three schemes can also be adopted, thereby realizing a variety of methods for changing the distance between the silica gel plate 3 and the impeller 2, ensuring that the nipples of cows of different sizes can be adapted during milking, the nipples of cows are not injured, the cows do not feel pain, and milking can be done quickly.
