Abstract

The invention relates to agriculture, to pulsator collectors of milking machines. The purpose of the invention is to reduce the maintenance costs of milking machines. The pulsator collector contains the chambers of constant 1 and 2 and variable vacuum 3, 4, 5, the control chamber 7 and the chamber 6 of constant atmospheric pressure. The control chamber 7 is made in the form of a movable in a vertical plane and placed inside the chamber 6 of the atmospheric pressure of the housing, one of the walls of which is made in the form of an elastic membrane 17, and a rod with valves 18 and 19 is mounted in the opposite wall. An additional chamber 5 of variable vacuum is located between chambers 6 and 2. During the stroke, the valve 8 is open, the valve 12 is closed, the vacuum is distributed into the inter-wall chambers of the teat cups. Under the action of a differential pressure force, the valve 18 is closed, and 19 is opened, the vacuum is distributed into the milking space of the teat cups. The housing 16 occupies the upper position. The vacuum inside chamber 7 is amplified, valve 12 opens, and valve 8 closes. The membrane 17 bends inside the housing 16. Atmospheric air flows into the inter-wall chambers, and a compression stroke occurs. With the rest tact, the intake of atmospheric air into the grinding chambers of the teat cups takes place. The housing 16 occupies the lower position. 3 il.

The invention relates to agriculture, in particular to the pulsator collectors of milking machines.

The purpose of the invention is to reduce the maintenance costs of the milking machine.

FIG. 1 shows a schematic representation of the proposed milking unit pulsator during a sucking stroke; in fig. 2 - the same, with the compression stroke; in fig. 3 - the same, with the tact of rest.

The pulsator collector of the milking machine contains chambers 1 and 2 of constant vacuum, alternating chamber 3-5 of vacuum, chamber b

Each of these valves and the cross section of the passage slit of the throttles 10 find the ratio between the cycles of the puly collector operating cycle. At steady state during the stroke, the valve 8 is open, the valve 12 is closed, from chamber 1 the vacuum spreads into chambers 3 and 4 and the interstitial spaces of the teat cups. At the same time, through channel 13, air is constantly sucked out of the control unit 7 of the chamber 7. Under the action of the pressure difference force in chambers 6 and 7, the housing 16 is in the upper position, the valve 18 is closed, and the valve 19 is opened. From chamber 2, the vacuum propagates into chamber 5 and the simple-empty atmospheric pressure and control chamber 7. An additional chamber 5–15 of teat cups, an alternating vacuum occurs between K2 - sucking the milk out of the udder nipples.

From chamber 6 into chamber 4 and through the slotted choke 10 into chamber 3 and the interstitial spaces of the teat cups, atmospheric air flows in under vacuum

The valve 11 is formed inside the rod. 11 The channel 13 connects chambers 3 and 7. The cross section of the channel 13 is regulated by a screw 14.

Control chamber 7 is located in the cavity of chamber 6 of constant atmospheric pressure and is made as a separate case 16, movable in the vertical section of the housing, closed from above by an elastic membrane 17 connected to the housing 16 by means of a collar. In the central hole of the membrane 17, a rod 11 is fixed with valves 8 and 12. Valves 18 and 19 are mounted on a rod 20 mounted in the bottom wall of the housing 16 and placed in an additional chamber 5 of variable vacuum. The latter, in connection with the aid of the nozzles 21, communicates with the teatplaces of the teat cups (not shown) and, with the help of openings closed by valves 18 and 19, has the ability to communicate with the constant atmospheric pressure chamber 6 or with the constant vacuum chamber 2 22 connecting it to the milk hose going to the milking bucket (not shown). Chamber 2 is continuously communicated with the help chamber of the manifold 22.

Pulse collector works as follows.

In order for the pulsator collector mechanism to work properly, the following condition must be observed: the working area of the membrane 17 must have the largest value, then the values of the areas corresponding to valves 12-19, 18-8 are decreasing. Depending on the size of the workers

life tact suck.

Further, atmospheric air is gradually supplied to the cavity of the control chamber 7 through channel 13, and the action of vacuum, which keeps valves 8 and 18 closed, decreases due to the fact that the working surface of valve 8 is smaller than the working surface of valve 18, under By the action of vacuum in the chamber 5, the valve 18 opens while simultaneously closing the valve 19. The housing 17 of the control chamber 7 is in the lower position. When this occurs, the intake of atmospheric air from the chamber 6 into the chamber 5 of an alternating vacuum and further into the podoskovye chambers of milking cups. There is a tact of rest. Then the valve 8 opens again and the valve 12 closes, the suction stroke begins, and the three-stroke cycle is repeated. If necessary, the frequency of the pulsations regulate the screw 14.

The invention makes it possible to ensure, more at 50, reliable and durable operation of the pulsator collector mechanism, to reduce the costs of production, operation and maintenance of the devices.
