ANALYSIS OF THE MASSAGE DEVICE OPERATION ON THE BASIS OF CYCLOGRAMS OF PRESSURE CHANGES IN ITS STRUCTURAL ELEMENTS

Abstract

The article discusses the design and technological scheme of the device for combined massage of the udder of heifers, which allows you to adjust the intensity of the pneumatic and mechanical components of the massage effect on the breast tissue. Based on the obtained cyclogram of pressure changes in the casing and suction cup of the massage device, the advantages and disadvantages of such devices operating in a two-chamber scheme, including a massage casing and an active working body with a power pneumatic chamber, are analyzed. The disadvantage of the massage device under study is the lack of a full restoration of blood circulation in the part of the udder of the animal with which the sucker interacts. The advantages of the considered design and technological scheme of the massage device include the possibility of regulating the intensity of the pneumatic and mechanical components of the massage in a wide range and allowing you to get two technological modes of operation of the device for preparing heifers for lactation.
