ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to teat cleaning devices of the type according to the preamble of claim
1
for cleaning and pre-milking the teats of animals. The present invention also relates to a method according to the preamble of claim
6
for cleaning and pre-milking the teats of animals.
DESCRIPTION OF RELATED ART
When dairy animals are to be milked it is necessary to first clean the teats of the animal to avoid dirt present on the teats contaminating the collected milk. It is also desirable (and even a legal requirement in some countries) to pre-milk the teats. By pre-milking is meant the first phases of milking in which:
the teat is stimulated in order to stimulate the milk ejection reflex and induce milk letdown; and,
the milking is started and the first drops of milk are collected separately for inspection and/or discarded in order to prevent contaminants, on or inside the teat from being transported into the rest of the milking machinery. During pre-milking it is desirable that the whole of the milk contained in the teat is extracted. This milk can then be inspected for signs of disease or contamination.
It is known from EP-A-0 527 509 to use a teat-cup containing water to clean the teat and then to use the same teat cup for milking. This requires extremely thorough, time-consuming cleaning of the teatcup between the cleaning phase and the milking phase.
Another device shown in DE 127 384 permits cleaning of the teats by vertical rotating brushes but this device is unable to premilk the teats.
SUMMARY
An object of the present invention is to provide a device and a method for cleaning and pre-milking which overcomes the problems associated with previous devices for cleaning and pre-milking.
The objects art achieved according to the present invention by means of a device and a method having the features mentioned in the characterising parts of the independent claims. Further developments and improvements of the present invention are mentioned in the dependent claims.
