FIELD: agriculture.SUBSTANCE: milking machine comprises teat cups (1), collector (2), pulsator (3), milk-vacuum hoses, attachment (4). The teat cups have under-teat (5) and intermural (6) chambers. The pulsator housing is axially aligned with the attachment housing and is mounted above it to form the transverse partition (7) common with the attachment. The pulsator is provided with chambers of constant vacuum (8), alternating vacuum (9), constant atmospheric pressure (10) and the control chamber (11). The chamber of alternating vacuum is connected by the channel (12) with the control chamber. The chambers of constant and alternating vacuum are divided by the valve (13). In the housing of control chamber (14) a valve is mounted with axial holes (15), which end surface due to the spring (16) rests on the collar (17). The control chamber of the pulsator is provided with an additional housing (18) forming the working chamber (19) under it. The transverse partition is provided with a central hole (20) with a rod (21) located in it. The rod with its lower end is secured to the thermostatic bellows (22) of the milk chamber (23) of the attachment. In the rod the transverse (28) and longitudinal (29) holes are formed linked to each other. The actuating mechanism in the form of a sucker (30) is located above the additional housing. The thermostatic bellows is mounted on the base (32) movable in an axial direction by means of threaded connection. The housing of the attachment has pipes for feeding (33) the milk in the milk chamber and outlet (34) into the milk-receiver (35).EFFECT: reduction of the cost of manual labour.2 dwg |
