Abstract

SUMMARY OF THE INVENTION: a device for controlling a milking process comprises a head guiding with a rod 4, a channel 2 and a groove 3 on its surface, a valve 13 installed in the intermediate milk chamber 9 of the housing 5, connected to the rod 14 and a float 15 having a needle. In the lower part of the glass 17, a sleeve 18 is pressed in with a calibrated hole into which the needle enters. During intensive milking, the float floats and lifts the valve 13, the shaft 4 and the head, the bracket 6 is released, and control of the milking mode begins. The bulk of the milk flows out through the lid fitting, and the needle of the float 15 maximally opens the calibrated hole of the sleeve 18 and the vertical oscillations of the needle during milking, cleans it. At the end of the milk transfer intensity, the milk is only discharged through the calibrated hole of the sleeve 18, the float 15, the valve 13 and the rod are lowered down. A thickened part of the needle enters the calibrated hole of the sleeve 18, which ensures the inhibited lowering of the float. 1 wp 1 ill.

Description

The invention relates to milking machines.

The purpose of the invention is to improve the milking process by allowing air to flow into the suction cups of the teat cups at the end of the milking.

The drawing shows a General view of the pneumatic sensor, section.

The device for controlling the milking process comprises a head with a fitting connected to a cylindrical guide 1 having an internal channel 2 connected to the head fitting and a groove 3 on the surface of the rod 4. The housing 5 has two nozzles - a milk one and a constant vacuum, and the sleeve 6 is pressed into the housing 5. having on the inner surface an annular chamber of constant vacuum 7 located in the upper part and an annular chamber 8 of atmospheric pressure located in the lower part, connected to the groove 4 of the guide 2, connecting the annular chamber 8 of the sleeve 6 by the intermediate milk chamber 9 of the housing 5 for supplying air to the suction cups of the teat cups at the end of milking. The bracket 10 is pivotally mounted on the housing 5 and serves to set the guide 2 to the upper position at the beginning of milking, the gasket 11 seals the housing 5 with the cover 12. The valve 13 is connected to the lower end of the shaft 14 by a float 15 with a needle. The gasket 16 seals the cover 12 with a glass 17, in the lower part of which a sleeve 18 is pressed in with a calibrated hole into which the needle of the float 15 enters.

The device operates as follows.

Before milking, the head, stem 4, valve 13 and float 15 were installed00

are mounted on the bracket 6 to the upper position. In this position, the piston is in the lower position, the cable from the piston to the DA-50 milking machine sags freely. The valve 15 opens and the vacuum is transferred through the milk hose to the milking machine. The DA-50 milking machine is placed under the cow’s mouth, the valve of the milk chamber is opened and the teat cups are put on the teats in turn. Milk begins to flow into the glass 17, and part of it is poured through the calibrated hole of the sleeve 18. The intensity of milk transfer has not yet begun.

In case of intensive milk delivery, the float 15 floats and lifts above the valve 13, the shaft 4 and the head, the bracket b is released under the action of its own weight, and control over the milking mode begins. The bulk of the milk flows through the nipple of the lid 12 into the milk line. The needle of the float 15 maximally opens the calibrated hole of the sleeve 18, and the vertical oscillations of the needle. pinch him.

At the end of the intensive milk transfer, the milk is discharged only through the calibrated hole of the sleeve 18 and the float 15, valve 13, rod 4 and head 1 are lowered down. A thickened part of the needle of the float 15 enters the calibrated hole of the sleeve 18, which is necessary to inhibit the lowering of the float 15.

If milk flow does not resume, the float 15, valve 13, rod 14 with channel 2 are lowered even lower, and rod 4 with channel 3 is immersed even deeper into the constant vacuum chamber 7 in the sleeve 6. The vacuum propagates into the cavity of the vacuum milking cylinder apparatus. As a result of the aforementioned movement, the valve 13 is closed, the transfer of vacuum to the milk chamber is stopped. And the air from the air chamber 8 of the sleeve 6 through the groove 3 of the shaft 14 is transferred to the chamber 9 of the housing 5, from which through the milk hose to the milk chamber and suction cups of the teat cups.

The cable is tensioned and the teat cups are easily removed, and the milking machine is pulled up.

During washing, the teat cups are attached to the washing heads of the washing system. The valve of the milk chamber of the milking machine is fixed open. The emphasis rises to failure and rotates around its own axis by 90 °, is fixed

in elevated position. This is necessary to ensure that valve 13 is opened for the entire period of circulation flushing. SUMMARY OF THE INVENTION 1. A device for controlling a milking process, comprising a milk receiving chamber with a lid, in which a central hole is made, a float placed in the chamber, and a needle with a needle a thickness varying in a longitudinal section installed in a cylindrical guide with the possibility of vertical movement of the rod with a channel in its upper part connected to the fitting m of the head, located between the rod and the guide in the upper part of the constant vacuum chamber with a fitting and in the lower an atmospheric pressure chamber with a fitting, milk and outlet pipes, a rod retainer, characterized in that, in order to improve the milking process by ensuring that air is sucked into the suction cups of the milking cups at the end of milking, it is provided located between the milk reception chamber and the guide intermediate milk chamber, the upper part of which is connected to the lower end of the rod and the lower one is installed in the central hole of the lid and connected to the float, grooves are made in the rod at the location of the constant vacuum and atmospheric pressure chambers, and the milk pipe is connected to the intermediate chamber. 2. The device according to claim 1, characterized in that the milk receiving chamber is provided with a sleeve with a calibrated hole, the diameter of which is larger than the thickened part of the needle.
