Description

FIELD OF THE INVENTION The invention relates to agriculture, in particular to regulating the vacuum in the pipelines of the milking machine.

The purpose of the invention is to reduce energy consumption while maintaining optimum dilution during milking,

FIG. 1 shows schematically an apparatus for stabilizing a vacuum in an air-fiber of a milking machine when milking into a bucket; Fig 2 is the same when milking in the milk line.

The device contains a two-speed electric motor 1, a button actuator 2, a control panel 3, an electrical wiring 4, an air pump 5, an additional air receiver 6, an air regulator 7, a vacuum indicator 8, a central air duct 9, a combined reactive damper 10 frequency oscillations, the final air ducts 11, regulators 12 sparse limiters, milk lines 13, air separator 14, milk counter 15, milk faucet 16. The limit controller contains a housing, a membrane 17 with a rod and a contact plate 18, an upper pair of contacts 19, a lower pair of contacts 20 of the lower level limit, and a spring 21 with a tension regulator 22. The device implements a method for stabilizing the vacuum in the air-fiber lines of the milking machine as follows.

When milking into buckets (Fig. 1) during the start of the milking installation, operate using the button of the manual actuator 2, console 3 controls, due to the absence of a vacuum in the air ducts, the lower pair of contacts 20 is closed and the pump 5 driven by the electric motor 1 at an increased rotation frequency, works with increased performance. The air pump 5 sucks air from the central duct 9 through the combined reactive dampers 10 oscillations from the final ducts 11. When the working magnitude of the dilution is reached, the diaphragm 17 rises under the influence of the vacuum and the contact plate 18 switches the upper pair of contacts 19. The control panel converts the electric motor and pump operating mode with the necessary capacity of the vacuum, the surplus of which is compensated by the air regulator 7 schestvl a vacuum indicator 8.

Include milking machines. During the operation of milking machines inside the line due to the air leaks, especially

during synchronous operation of the pulsators, air suction when putting on teat cups, etc., not only vacuum fluctuations are observed in the system - the system enters

resonance.

In order to reduce the effect of resonant oscillations on the mutual operation of the milking machines, combined reactive dampers of 10 oscillations are included, which

0 remove the effects of frequency oscillations of the final air ducts 11 on the central 9, and of the central one - on the final 11.

The central air duct 9 not only transmits, but also takes part in extinguishing

5 oscillations - stabilization of the vacuum, and during periods of intensive vacuum creation a large diameter air duct is not a throttle, which contributes to an increase in the productivity of the entire system.

0In the case of synchronous operation of the pulsators of milking machines, putting on milking cups, dropping of milking machines, the vacuum value falls below the permissible by zootechnical norms,

The 5 limit regulator 12 switches the pump 5 through the lower pair of contacts 20 to improved performance, whereby the working upper limit of the vacuum is restored before the vacuum in the central 9 and final 11 air ducts is reduced — the entire system.

When milking into the milk line (Fig. 2) due to the fact that the milk line is completed with an air duct system and an air fiber system, everything described for the case of milking into a bucket also occurs during milking into the milk line.

In the system of milk lines 13 in the period

At the start of the installation, the vacuum level rises to the required limits.

When connecting milking machines to the air duct 13 due to improperly putting on the teat cups,

5 air slopes in the suction part of the teat cup, the suction of air through the manifold, necessary for transporting milk to the milk line, are observed vacuum fluctuations, which

0 in the proposed installation are eliminated by the action of the combined reactive absorbers 10 oscillations installed in front of the air separator 14.

In the case of milking machines entering

5 frequency resonance, their drops include the lower pairs of contacts of the regulators 12 limits, the air pump is switched to increased performance and vacuum through the wide central air duct 9 through valve 23

connecting the milk line quickly recovers to the worker. When the upper operating limit is reached, the upper pair of contacts of the regulator 12 limits converts the electric drive and, accordingly, the pump to a lower design capacity.
