And by connecting the inlet I to the connection port T provided in the predetermined location of the vacuum line V, a vacuum pressure is supplied to the inside of the bucket body B and each teat cup t, and milking is started. The operator confirms the end of lactation while observing the amount of milk in the bucket body B, removes the inlet I from the connection port T, shuts off the vacuum, removes the teat cup t from the teat, and finishes the milking operation. Then, necessary post-processing is performed with respect to the raw milk accommodated in the bucket for milking.

  Equipment that comes in direct contact with milk in a milking machine must always be kept clean and prevent the propagation of germs. Therefore, usually, before and after the milking operation, the remaining milk is automatically removed by flowing cleaning water such as water and acidic / alkaline cleaning liquid through the milking line in a predetermined order. In a normal washing procedure, milk components are first washed away by first rinsing with room temperature water or lukewarm water. Next, the dirt that is difficult to dissolve is removed by sequentially performing decomposition cleaning of fat by circulation cleaning with an alkaline cleaning liquid and removal of inorganic substances by acid. Finally, rinse with water or lukewarm water to wash away the cleaning solution. The vacuum piping type milking machine is provided with a function of automatically performing these washing steps using a milking pipe and a vacuum source.

For example, in the automatic cleaning of a vacuum piping type milking machine described in Japanese Patent Application Laid-Open No. 9-56288, a predetermined amount of cleaning liquid is stored in a cleaning tank in advance, and a discharge-side piping of a feeding pump is connected to the cleaning tank and cleaning is performed.

  Milking buckets need to be kept clean like other milking equipment, but because they are used independently of vacuum piped milking machines and are large in volume, they have been mainly washed manually so far. It was. In this case, since the milking bucket generally has a shape in which the mouth portion is relatively narrow and widens toward the back, there has been a problem that it is easy to leave a washing residue on the inside and complete washing is difficult. As an automated mode, there is known a configuration in which the bucket lid is removed and turned upside down, and the cleaning liquid is sprayed into the interior from the lower side for cleaning. However, this cleaning method requires time and effort to lift and attach the bucket upside down, and lift and remove it again after cleaning.

  Therefore, the first object of the present invention is to provide a bucket cleaning device capable of automatically cleaning the inside of a bucket by connecting a milking bucket to a vacuum piping type milking machine having an automatic cleaning function.
