Description

Technical Field

[0001] This utility model relates to the field of livestock breeding technology, and in particular to a milking cup structure and milking system for dairy cows. Background Technology

[0002] With increasing public concern for food safety, the quality and safety of dairy products have become increasingly important. As the very beginning of the dairy industry chain, raw milk's quality and safety directly impact the entire chain and are a prerequisite for product quality and safety. Major risk factors affecting the quality and safety of raw milk include veterinary drug residues, disinfectant residues, and microbial contamination. In the raw milk production process, milking equipment is the core equipment ensuring milk production efficiency and quality. The milking cup, as a key component that comes into direct contact with the cow's teats, directly affects milking efficiency, teat health, and raw milk quality. Currently, most mainstream milking cups consist of a cup body, rubber liner, and connecting tubing. They connect to a vacuum pump to create negative pressure, simulating the natural sucking action of a calf to complete the milking process. These cups are widely used in large-scale dairy farms in tubular milking machines, rotary milking machines, and other similar equipment.

[0003] Traditional milking cups typically have outer shells made of ordinary rubber, lacking antibacterial design. Since the outer shell is in direct contact with the cow's teats for extended periods, ordinary rubber cannot inhibit bacterial growth, allowing inflammatory bacteria such as Staphylococcus aureus and Streptococcus to adhere to the surface and multiply rapidly. Furthermore, the design of the traditional milking cup outer shell (the rubber part in contact with the teat) is inconvenient to disassemble and replace, lacking easy replacement features. Disassembly and assembly require tools and are cumbersome and time-consuming. Especially in large-scale farms, where a large number of milking cup outer shells need to be replaced and cleaned daily, this difficult-to-replace design not only consumes significant manpower and time but also risks damage to the outer shell or cup body due to improper tool handling, increasing equipment maintenance and replacement costs and failing to meet the demands of efficient milking operations in large-scale farming scenarios.

[0004] Currently, no effective solutions have been proposed for the problems of traditional milking cup outer shells lacking antibacterial properties and being difficult to disassemble and reassemble in related technologies. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a milking cup structure and milking system for dairy cows, thereby solving the problems of traditional milking cup outer shells lacking antibacterial properties and being difficult to disassemble and assemble.

During the process, the first antibacterial outer layer 141 in contact with the nipple continuously releases silver ions through the nano-silver coating to destroy the microbial cell structure, which can continuously inhibit the growth of bacteria on the nipple surface (such as Staphylococcus aureus, Streptococcus and other common inflammatory bacteria) during milking, and prevent bacteria from entering the milk tank with the milk and contaminating the raw milk.

The removed sleeve element 121 and antibacterial outer jacket unit 140 are placed in the designated cleaning area for cleaning.

[0104] The advantages of this invention are that the main body unit 110 and the sleeve unit 120 are detachably connected and installed, ensuring that the negative pressure environment does not leak and that milk is transported smoothly, while also allowing for separate cleaning, reducing the risk of bacterial growth due to milk residue in the channel; the sleeve unit 120, the first connecting unit 130, the antibacterial outer sleeve unit 140, and the second connecting unit 150 can be used to assemble, disassemble, and position the antibacterial outer sleeve unit 140, which can be fitted onto or removed from the sleeve unit 120 without the need for tools, simplifying the replacement and cleaning process. At the same time, the sleeve unit 120 restricts the displacement of the antibacterial outer sleeve unit 140, ensuring a tight fit during milking; and the antibacterial outer sleeve unit 140 has antibacterial function, inhibiting the attachment and reproduction of inflammatory bacteria such as Staphylococcus aureus and Streptococcus, preventing bacteria from contaminating the raw milk and reducing the risk of teatitis in dairy cows.

[0105] Example 2 This embodiment relates to the milking system of this utility model.

[0106] like Figure 9 As shown, a milking system includes a milking cup structure 100 as described in Embodiment 1 and a vacuum device 200. The vacuum device 200 is connected to the main body unit 110 of the milking cup structure 100 and is used to generate a vacuum.

[0107] Specifically, the vacuum device 200 is connected to the main component 111.

[0108] In some of these embodiments, the vacuum device 200 is a vacuum pump.

[0109] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
