SU1246940A1 - Collector for milking apparatus - Google Patents

Description

This invention relates to agriculture, in particular to milking apparatus collectors.

The purpose of the invention is to simplify the design of the milking unit collector.

FIG. 1 shows schematically the collector of the milking machine during the sucking stroke; in fig. 2 - the same with the compression stroke.

The milking machine collector has a housing in which milk collection chamber 2 with a vacuum pipe 3 and four milk pipes 4, an alternating vacuum chamber 5 with four air pipes 6, a control chamber 7 with a branch pipe 8 are located below each other. The control chamber 7 is separated from the camera variable vacuum membrane 9 and the plate 10, and the rod 1 passes through the hole in the membrane 9, which is larger than the diameter of the rod, but less than the diameter of the plate. The rod 11 is inserted into the guide 12 located in the partition 13 between the milk collection chamber 2 and the variable vacuum chamber. The rod 11 has a stop 14, limiting its movement upwards. In addition, a valve 15 is located on the rod 11, limiting the nepeMenj, eHne of the rod 11 downwards and closing the opening between the milk-collecting chamber 2 and the alternating vacuum chamber 5. In the rod there is a calibrated channel 16 through which the variable vacuum chamber 5 communicates with the milk-collecting chamber 2. In the chamber 2 there is a non-return valve 17 overlapping the nozzle 3.

Collector milking apparatus works as follows.

The nozzle 3 collector is connected to a constant vacuum source, for example, to a milk line or a milking bucket of a milking machine (not shown), and nozzle 8 to a variable vacuum source, for example, a pulsator (not shown), which operates at a given pulsation frequency. Through a patch of 5 cuts 3, a milk collecting chamber 2 and nozzles 4, a constant vacuum is transferred to the suction chambers of the teat cups (not shown). If to the control chamber 7 through the pipe 8 is transmitted from the pulsator

10 pressure, then the membrane 9 presses against the plate 10 and rises up with it until the shaft 11 by the stop 14 contacts the wall of the chamber 7. Moving the rod 11 with the valve 15 upwards opens the opening in the wall 15 and thus the joint a milk-collecting chamber 2 with an alternating pressure (vacuum) chamber 5. As a result, in the chamber 5 and in the interwall chambers of the teat cups a vacuum is equivalent to chamber 2, which corresponds to the sucking tact.

When supplied to the control chamber 7 from the atmospheric pressure pulsator, the membrane 9 with the plate 10 and the stem 11 moves downward until the valve 15

25 does not block the opening in the partition 13. At the same time, due to the pressure difference in the chambers 7 and 5, the membrane 9 bends downwards and provides air from the control chamber 7 to the chamber 5 and the inter wall chambers of the teat cups, which corresponds to

30 tact of compression.

The udder milk transported from the teats is transported during the suction and compression cycles due to the pressure difference created by sucking air into the milk collection chamber 2 from chamber 5 through the calibrated channel 16.
