Description

A multifunctional milking cup

technical field

The utility model relates to a milking cup used for milking dairy animals, more specifically, relates to a multifunctional milking cup, which can be widely used in milking equipment of rotary table type, pipeline type and mobile cart type.

Background technique

Milking cups are used in automatic milking equipment for milking cows. During the entire milking process, the teats of cows are inserted into the milking cups. Before milking, the vacuum pump evacuates the milk bucket or the main milk line, and the milk liner is connected to the main milk line through the short milk tube. There is a pipe joint connected to a pulsator on the pulsation chamber between the milk cup shell and the milk liner. The pulsator makes the pulsation chamber alternately switch between vacuum pressure and atmospheric pressure periodically. When there is atmospheric pressure in the pulsation chamber, the pressure is greater than that of milk. The vacuum pressure in the liner will cause the breast liner to shrink and compress the nipple; when there is a vacuum pressure in the pulsating cavity, the pressure difference between the pressure and the vacuum pressure in the breast liner will decrease, so that the contracted milk liner will open. The negative pressure in the main milk pipe will cause the cow to be milked.

Most of the current milking cups are composed of a rubber teat cup liner (milk liner) and a stainless steel jacket, and the milk liner is a consumable that is often worn out, so it needs to be replaced frequently; and the replacement of the milk liner is a time-consuming and difficult task , it is required to disassemble the inner liner of the milk cup from the shell and install a new milk liner in the shell.

Faced with this situation, the standardized milking process includes cleaning, disinfection, pre-excitation, inspection of three milks, milking, medication The milkers on the ranch clean the cow’s teats separately before milking. In addition to teat cleaning, the disinfection and air drying of the cow’s teats, and the medicated bath after milking are also done manually by the milkers, which is time-consuming. Laborious, low work efficiency, especially for some small and medium-sized pastures, the management is not standardized. In order to save time and effort during the milking process, the milking workers will always intentionally omit a few of the milking processes mentioned above. As a result, neither the quality of the dairy product nor the health of the udder of the cow can be guaranteed.
