This invention relates to agriculture. The purpose of the invention is to improve the measurement accuracy. The milk meter contains a receiving 1 and measuring 2 chambers, communicated by an opening 3. An additional measuring chamber 11 communicates with the main measuring chamber 2 and communicates with the beaker 8 by a valve 12. The rods 15, 17 are fixed at the ends of the beam 16, the center of which is fixed on the membrane 19 of the mode switch work. The exuded milk enters the measuring chamber 2 and the additional chamber 11. When the pulsator 23 is switched, the spring 22 raises the diaphragm 19, the yoke 16, the rods 15.17 of the valves 12,13,14 and the chamber 11 communicates with the beaker 8. 1 Il.

Description

This invention relates to agriculture, in particular to milk meters.

The purpose of the invention is to improve the measurement accuracy.

The drawing shows a diagram of the milk meter.

The milk meter contains a receiving 1 and main measuring 2 chambers interconnected by an inlet 3, a receiving chamber 1 by an air nozzle 4 communicating with a milk nozzle a bis collector of a milking machine (not shown) the receiving nozzle b, the main measuring chamber communicating with atmospheric air by air jet 7, the counter is equipped with a beaker 8. An additional measuring chamber 11 is connected to the main measuring chamber 2 by an air 9 and milk 10 holes, which is disconnected from the 8 k beaker Apane 12, the main measuring chamber 2 is separated from the milk nozzle 5 by the bottom flap 13 and from the receiving chamber

1 - the upper valve 14, both of these valves are mounted on a single rod 15 attached to the shoulder of the rocker arm 16, a hollow rod 17 is attached to its second shoulder, on which the valve 12 is mounted. In the upper part of the hollow rod, a window 18 is made, the rocker 16 in the middle part attached to the membrane 19, separating the air 20 and working 21 (variable vacuum) switch mode of operation. A spring 22 is located in the working chamber 21, and a pulsator 23 connected by a channel 24 (variable vacuum) with a mode switch and a channel 25 (constant vacuum) with a receiving chamber 1 is mounted in the upper part of the counter, the working 26 and the controller 27 of the pulsator chamber are connected by a throttle channel 28, the cross section of which is adjusted by the screw 29.

The milk meter works as follows.

The milk meter is attached to the milk-COCOOPER (on the basis of HP ppk no1 shtppt |

The air that is put on the nozzle 5, the air is pumped out through the nozzle 4 from the receiving chamber 1 and through the nozzle 6 from the collector and the milking apparatus, through the inlet 3 the air is pumped out of the main measuring chamber 2, then through the channel 9 from the chamber 11 and through the window 18 in the rod 17 from the beaker 8. Air is pumped out through the channel 25 from the pulsator 23, its valve is set to the suction stroke position, i.e. air is pumped out from the chamber 26, the vacuum is distributed through the channel 24 to the operating mode switch 21, the pressure switch meters of air from the chamber 20 to the membrane 19, it goes down, squeezes the spring 22, through the rocker 16 force is transmitted to the rods 15 and 17, the valve 12 separates the chamber 11 and the beaker 8, the valve 13 separates the main measuring chamber 2 and the nozzle 5. The eaten milk enters the receiving chamber 1, through the window 3 - into the measuring chamber 2, through the channel 10 - into the additional chamber 11. The level of milk in chambers 2 and 11 is set equal, as in communicating vessels, and accumulates in them due to the fact that valves 12 and 13 are closed.

When the pulsator 23 switches to the massage stroke position, the air is pumped out from the control chamber 27 through the channel 28, the valve drops down and air enters the chamber 26, it also penetrates into the chamber 21 and the pressure there is equal to the pressure in the chamber 20. The spring 22 raises diaphragm, rocker, valve stem 12, 13, 14 in the upper position. The valve 14 closes the opening 3, the valve 13 connects the nozzle 5 to the main measuring chamber 2, the valve 12 connects the chamber 11 to the beaker 8 and closes the opening 10, separating the lower part of the chamber 2 and 11. By stopping the air from the chambers 2 and 11 through the opening 3 and the fact that the opening of the nozzle 5 is in the milk, the air entering through the nozzle 7 creates a slight pressure in the chambers 2 and 11, which helps squeeze the milk out of them. The operation of the milking machine

continues without change, the milk enters the receiving chamber 1.

After switching the valve of the pulsator 23, the milk begins to flow again into

measuring chambers 11 and 2. The frequency of operation of the pulsator and valve switching mechanism is regulated by a screw 29. With a volume of the main measuring chamber equal to 1 dm3 (0.001 m3), the frequency of operation of the pulsator 23 should be 3-4 times per minute. Moreover, the measurement accuracy does not depend on the ripple frequency. The measurement accuracy does not depend on the amount of the last portion of milk.

The counter can be executed both individual and group. The operation mode switch can be made in the form of an electromagnet controlled by a time relay.
