A Leakage Self-checking Control System for Milking Cups

Abstract

The invention discloses a leakage self-detection control system for a milking cup, belonging to the field of automatic milking equipment of milk yielding animals. The leakage self-detection control system comprises a milking cup, a first pressure sensor, a second pressure sensor, a three-way valve and a controller, wherein the first pressure sensor is used for detecting the pressure in a milk liner cavity, the second pressure sensor is used for detecting the pressure in a pulsation cavity, the three-way valve and the controller are arranged in a main milk pipeline, and the first pressure sensor, the second pressure sensor and the three-way valve are respectively electrically connected with the controller; and the first pressure sensor and the second pressure sensor are used for feeding detected pressure signals back to the controller, and the controller controls the three-way valve to execute corresponding on-off actions. According to the leakage self-detection control system, a series of problems that the milking efficiency is decreased, the milking cup is difficult to clean, and the like when the milking cup is broken to leak air and milk can be effectively solved; furthermore, the problem that the milking cup and milk are polluted after pollutants are sucked into a milk pipe by vacuum negative pressure which is not timely turned off when the milking cup is damaged can be effectively solved; and furthermore, the automatic control of the milking process is realized.

Description

technical field [0001] The invention relates to a milking cup control system used for milking dairy animals in automatic milking equipment in animal husbandry, more specifically, to a teat cup leakage self-checking control system. Background technique [0002] Milking cups are used in automatic milking equipment for milking dairy animals. During the entire milking process, the teats of dairy animals are inserted into the milking cups. The milking cup is usually composed of a rubber teat cup liner (milk liner) and a jacket. As we all know, the teat cup liner is a vulnerable part in the entire milking cup. The milk liner manufacturer recommends that it be replaced every 1,000 cows. At present, foreign countries Most of the methods adopted by the pastures are to use a fixed number of times. This has indeed avoided the milk liner from leaking to a certain extent and improved the milking efficiency. However, some milk liners have not yet reached the end of their life. , which br...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a self-checking control system for milking cup leakage. By adopting the technical solution of the present invention, it is possible to timely detect and solve the problem of air leakage and milk leakage caused by the breakage of the milking cup. , and lead to a series of problems such as reduced milking efficiency and difficulty in cleaning the milking cup; and it can effectively solve the problem of milking due to the vacuum negative pressure in the milk liner not being closed in time when the milking cup is damaged. Contamination of cups and milk; Realize automatic control of the milking process
