Description

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

The purpose of the invention is to increase the efficiency of milking by changing the ratio of sucking and compression strokes, depending on milk yield.

The drawing schematically shows the pulse collector of the milking machine, General view.

The pulse collector contains a milk chamber 1 with nozzles 2 for connecting to the suction cups, separated by a conical partition 3 with a valve 4 from the variable vacuum chamber 5 with nozzles 6 for connecting to the interwall chambers of the milking cups, a control chamber 7, separated from the variable chamber 5 by an elastic membrane 8 interacting with the rod 9. The control chamber 7 is connected to the internal cavities of the milk chamber 1 and the chamber 5 of the variable vacuum channel 10 with the adjusting screw 11. An additional pipe 12 is connected the inner cavity of the chamber 1 through the membrane 13. The channel 10 crosscuts with an adjusting screw 11 in communication with the vacuum chamber 5 and variable additional nozzle 12, is placed an additional control chamber 14 with the membrane 15.

The pulse collector of the milking machine operates as follows.

At the beginning of milking, the vacuum from the milk line (not shown) is distributed into the milk chamber 1, and then through the nozzles 2 under the nipples of the cow's udder. The data center is opened by a vacuum in the milk chamber 1 and the vacuum enters the chamber 5 of an alternating vacuum, nozzles 6 and. in inter-chamber chambers of milking cups. There is a sucking beat. At the same time, atmospheric pressure is sucked out from the additional control chamber 14 along the channel 10 as well as from the control chamber 7, the membrane 8 is balanced by vacuum, bending upward, closes the valve 4. The variable vacuum chamber 5 is connected to the atmosphere, air through the nozzles 6 enters the interwall milking space glasses. There is a compression beat.

Atmospheric pressure enters the control chamber 7, and the process is repeated.

Prior to the occurrence of the stock of milk of the cow in the milk chamber 1, the vacuum and the membrane 13 are concave inside the milk chamber 1 as much as the membrane 15 of the additional control chamber 14 is concave down. Therefore, when switching from a suction stroke to a compression stroke, and vice versa, the cross section of the input part of the channel 10 of the additional control chamber 14 changes and affects the state of the sucking and compression strokes.

During intensive milk flow, when the suction stroke is preceded by a compression stroke, atmospheric pressure is sucked out from the control chamber 7 and the additional control chamber 14. With intensive milk transfer and a vacuum drop in the milk chamber 1, the membrane 13 bends along the vertical axial line of the pulse collector, and the membrane 15 bends up to the input part of the channel 10. The cross section of the input part of the channel 10 decreases the more the vacuum increases in the control chamber 7 and the additional control chamber 14. As a result of pressure differentiation c. In chambers 1.7 and 14, the cross section between the membrane 15 and the inlet of the channel 10 is reduced, thereby prolonging the suction stroke.

The compression stroke is preceded by the suction stroke, atmospheric pressure of the control chamber 7 and the additional control chamber 14 is filled from vacuum to a positive pressure equal to the pressure of the environment (atmospheric). Therefore, with a constant vacuum in the milk chamber 1, the cross section between the membrane 15 and the inlet of the channel 10 changes from the maximum at the beginning of the process to the minimum at the end of the process, contributing to the acceleration of the transition from compression to suction.

Thus, during milking, the ratio between sucking and squeezing strokes changes, consistent with milk yield.
