The article discusses the concept of a unified approach to the development of pneumomechanical massage devices and milking machines. The practical implementation of this approach is considered. An improved pneumomechanical massage device is proposed. The main function is assigned to reduced pressure (vacuum) when performing technological operations of udder massage. The mechanical component of the device fulfils auxiliary function. The presence of an independent element in the suggested structural scheme of the device for the combined massage of heifers’ udders is substantiated. The change of pressure is fulfilled by a principle of counter-phase in a massage bell. This technical solution allows to increase efficiency of unloading cycle and to provide full restoration of blood circulation in the udder of an animal. The analysis of working process of the massage devices is carried out. An analysis of pressure changes in massage devices was made, a diagram of pressure changes in a massage bell and in a massage element of the device is drawn. The proposed design will eliminate the disadvantages of the device for pneumatic massage of the udder of heifers. The device allows regulation of pneumatic massage parameters for massage bell and massage element in limits of 20-25 and 40-48 kPa respectively.
