Description

one

The invention relates to agriculture, namely to the process equipment used in the milking of animals, and can be used in milking machines. five

A milking machine is known, including teat cups, pulsator collectors and a piping system for connecting a vacuum and discharging milk i.

However, when using such 10 milking machines, milking is carried out by constant vacuum, which leads to animal disease with mastitis.

The closest in its TexjiH4ej; -i5 essence and the result achieved is a milking machine, including cups connected to a pulsator collector, the control chamber of which is communicated with the atmosphere through 20 droplets, covered by a membrane separating the atmospheric pressure chamber from the dairy chamber, the tube of which is connected to the milk flow sensor, which interacts with the air flow regulator, communicated with the milk chamber and the source of overpressure 2.

The operation of the said milking machine can also lead to

left cows due to the inertia of the pneumomechanical system as a whole.

The purpose of the invention is to increase the safety of milking by reducing the inertia of the air flow controller.

The goal is achieved by the fact that the milk flow sensor is made in the form of a throttle diaphragm installed in the milk branch pipe.

The drawing shows the proposed milking machine, a general view.

The proposed milking machine contains a cup 1, the interwall chamber of which is in communication with the variable vacuum chamber 2 of the pulsator collector 3, and the underflow chamber with the milk chamber 4 separated from the atmospheric pressure chamber 5 by a membrane 6 covering the nozzle 7 connecting the atmospheric pressure chamber 5 and the control chamber B, connected to the variable vacuum chamber 2 by means of a pipeline with an adjustable choke 9.} Samera 2 variable vacuum through a membrane-valve mechanism 10 communicated with a constant vacuum chamber 11 fed from line-vacuum. Milk chamber 4 of the pulsator collector 3 has nozzles 12 for discharge of milk

air inlet pipes, a throttle diaphragm 14 is installed in the nozzle 12 for the removal of young, and an adjustable choke 15 is installed in the nozzle 13 for the air inlet; 14,

The apparatus works as follows: “About the T1 unit's connection; to the vacuum and air lines of the barn, a vacuum is formed in the collecting container and through the throttle diaphragm 14 and the suction port 12 in the mist-15 chamber 4 of the pulsol collector 3 and then in the spout of the teat cup 1. At the same time, a vacuum is formed in the chamber 11 of a constant vacuum and switches the diaphragm-20 valve mechanism 10 to the upper position, through the chamber 2 - the vacuum penetrates into the interwall space of the DOILER cup 1 and one, then into the control chamber 8

it to a certain level, in which the PIOM membrane-valve mechanism 10 goes to the lower position, and the air is removed through the variable vacuum chamber 2 into the interstitial space of the teat cups 1 and 30 through the throttle 9 - into the control, chamber 8. . , .

The speed of filling and emptying the control chamber depends on the resistance of throttles of the nozzle-gate type 35, i.e. from the deflection of the membrane 6, which separates the milk chamber 4 from the chamber 5. With a larger deflection of the membrane, the filling rate increases and the emptying rate decreases, i.e. The AQ clock step increases, and the compression stroke decreases. The deflection of the membrane 6 depends on the consumption of milk. So at the initial moment when the breastfeeding has not yet arrived, resistance to the throttle diaphragm 14 will be minimal, 45 therefore there will be almost no vacuum, and therefore air tube 16 will be maximized, so the flow regulator will open air-50 of the Spirit, and the air through the nozzle 13 pOtupytv milk chamber 4, extinguish the vacuum in it to a minimum. At the same time, the deflection of the membrane 6 will be minimal, meaning that the milking machine will work 55 on a short stroke of sucking and a long .Tact of compression, i.e. mode stimulation, with a small vacuum under the nipple.

With the onset and increase in the flow rate, the resistance to the throttle diaphragm 14 increases, hence the vacuum behind the diaphragm 1 decreases, and in the pneumatic chamber 17 deflection, the Wings 16 decrease, causing the adjustable throttle 15 to close. chamber 4 is set to a maximum vacuum, membrane 6 bends as much as possible, and the device switches to the mode of long suction stroke and short compression stroke.

Depending on the characteristics of the air flow regulator, the dummy unit can operate in a stable mode. If the characteristic is linear, it stabilizes the mode of operation; if the characteristic is not linear, it performs regulation depending on the milk plant. ..,, .

The use of milking machines with automatic control of the preedi process will reduce the incidence of mastitis in cows and increase milk production in the range of 10-12%. Working with these devices does not require strict control, as the overexposure of the devices on the udder is safe, therefore, up to p can milk animals with a large number of devices.
