Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cylindrical teat wiping device for wiping a teat of a dairy cow before milking with a teat cup, and discharging cleaning sewage from a cleaning case by a negative pressure air flow.
[0002]
[Prior art]
For hygienic production of milk and control of mastitis in dairy cows, a method of sterilizing a nipple by wiping with a disinfecting cloth before milking or dipping in a chemical solution such as an iodine agent is generally performed. However, since work preparations and procedures are troublesome, many dairy farms do not perform sufficient work and do not have a sufficient disinfection effect.
[0003]
In order to cope with these problems, a brush and a cleaning case that are rotated by an electric motor or a pneumatic drive in a cleaning case provided with a teat insertion opening as described in Japanese Utility Model Laid-Open No. 6-86451 and Japanese Patent No. 2707216. There has been proposed an apparatus for mechanically cleaning a teat with a cleaning liquid supplied therein. And these apparatuses are supposed to dry a teat by the airflow accompanying suction.
[0004]
In addition, the nipple wiping device incorporated in the milking robot includes washing using roll brushes that rotate inward with two parallel axes installed horizontally, and in the milking teat cup and nipple wiping. It is known that there is a system in which washing water is supplied into a dedicated teat cup and washed by a mixed flow of air and washing water for pulsation and suction. However, according to the latest report of a milking robot researcher, there is no current teat wiping device that can sufficiently remove dirt up to the tip of the teat, and the milking robot that will be developed in the future has sufficient performance There is a need for equipment. A type that can sterilize the tip of the teat is not a type that supplies cleaning water into the teat cup, but is disclosed in Japanese Patent Application Laid-Open No. 11-313566. It is not intended for use in milking sites.
In addition, cleaning and teat disinfection by soft spraying should not be effective unless the teat has relatively little dirt.
[0005]
In addition, a method for removing dirt and disinfecting by immersing a nipple in the nipple washing cup and immersing the nipple in it to apply ultrasonic waves is disclosed in Japanese Patent Application Laid-Open No. 2000-116261. The nipple disinfection dipping cup is always tilted, and it seems difficult to work without spilling the cleaning solution with this method. When working with cowling milked by cows, work on the cow bed is not allowed, and it is prohibited to pour the cleaning solution onto the cow bed.
[0006]
The brush described in the above-mentioned Japanese Patent No. 2707216 is premised on the action on the nipple tip. However, since the action depth is constant, it is expected that the brush will not reach the tip for a short nipple and is long. It is expected that the base of the nipple cannot be cleaned. In addition, since the system is driven using the air flow by suction, the apparatus diameter becomes large, and it seems that there will be a problem in work for cows with a narrow nipple interval.
[0007]
An apparatus similar to that described in Japanese Utility Model Laid-Open No. 6-86451 is known, but the grip that the operator holds is either a fixed type or a movable type, and the grip protrudes from the cleaning case. If the nipple insertion port is separated from the gripping position, it is difficult to insert the nipple when the nipple is difficult to see or the nipple spacing is narrow, and the gripping position should be as close as possible to the nipple insertion port that can be handled with the same feeling as the teat cup. .
[0008]
[Problems to be solved by the invention]
In the present invention, it is intended that anyone can easily and surely obtain a sterilization effect of the nipple by the mechanical wiping action of the cleaning liquid and the rotating brush. The purpose is to disinfect the area where the teat liner is in contact with the teat liner from the base of the nipple to the tip of the dairy cow. (1) It must be compatible with the nipple thickness (φ15-40) and length (40-70 mm). (2) When the nipple interval is narrow, the nipple after wiping should be reduced in size so as not to be contaminated by the outside of the apparatus. (3) It is necessary to drain water from the surface of the nipple so that water does not drip after completion of washing of each nipple so that bacterial infection does not occur from the mouth of the nipple.
The present invention is intended to realize a teat wiping device that satisfies these requirements.
[0009]
