Technical Field

[0001] The utility model relates to the technical field of automatic milking devices, in particular to an automatic milking device for cows. Background Art

[0002] Milking is an important task in farms of dairy goats, cows and other dairy livestock. With the continuous advancement of scientific and technological modernization and industrial modernization, people's living standards have been greatly improved, and the use of dairy products is also increasing. Dairy products are rich in various trace elements, which are beneficial to people's physical and mental health. For a long time, milking has been mainly done manually, which is not only time-consuming and labor-intensive, but also requires a high level of technical proficiency of milking workers, and sanitary conditions are difficult to guarantee. In order to solve the problems of time-consuming and labor-intensive manual milking and high technical requirements, some breeding companies have also developed some simple auxiliary milking tools, but the milking efficiency and effect are not satisfactory, resulting in still having to rely heavily on manual milking.

[0003] At present, publication number CN112154920A discloses a movable automatic milking machine, which realizes electric control of milking through the setting of an electric breast pump; realizes automatic control to stop milking through the setting of a weight sensor to avoid waste of fresh milk; through the setting of a refrigerator and an ice water tank, the squeezed fresh milk is cooled and refrigerated in time, thereby maximally maintaining the nutritional components of the fresh milk and improving the quality of the fresh milk; milking with the milking machine saves time and effort and greatly reduces labor costs.

[0004] In order to solve the problem of automatic milking of cows in the above technical solution, the existing technology adopts the setting of a refrigerator and an ice water tank to cool and refrigerate the squeezed fresh milk in time. However, after milking, it is still necessary to manually remove the cup, which leads to the problem of low milking efficiency. Utility Model Content
