CO The invention relates to agriculture, in particular to devices for recording the amount of milk in the milking process. Devices are known for measuring the amount of milk during the milking process, using the principle of batch-counting the flow of a product by volume, where portions of milk are taken into measuring tank 1. A disadvantage of the known device is the low accuracy of calculating the total weight of the milk produced, since its density in various animals varies widely. The closest to the present invention is a milk counter containing a receiving chamber that communicates in the upper part of the nozzle with the milk line and the milking machine, and in the lower part, the nozzle with the metering chamber connected with the openings with the atmosphere and the drain chamber passing into the milk line and counting sensor h. However, this device does not provide a high accuracy of accounting for individual doses and the residual amount of milk. The aim of the invention is to increase the accuracy of milk accounting. This goal is achieved by the fact that the measuring chamber in the middle part has a funnel-shaped thickening in which the outlet opening of the nozzle connecting the receiving and measuring chambers is located, the latter being provided with a conical valve with a skivom holes connected from above to the "1 element" passing through an opening that communicates the measuring chamber with the atmosphere with a dynamometer, and from the bottom — rigidly connected to a receptacle for receiving portions of milk, made cup-shaped, equipped with a drain pipe in the form of a siphon and located above the the hole informs a measuring chamber with a drain, and the diameter of this hole is smaller than the diameter of the bowl-shaped container. Figure 1 shows a milk meter with a raised valve, longitudinal cut; figure 2 - the same, with the valve lowered. The milk meter contains the receiving chamber 1, which is connected in the upper part by the nozzle 2 with the milk actuator 3, and the nozzle 4 - by the milking machine (not indicated), the measuring chamber 5, which is connected with the lower part of the receiving chamber 1 by the nozzle 6, and also with the atmosphere by the opening 7 and with a drain chamber 8, passing through a hole 9 in the milk line 3 and with a hole 12 with the sensor 10 of the counting mechanism 11. The measuring chamber 5 has a capacity of 13 cup-shaped forms for receiving portions of milk coming from chamber 1 through the nozzle 6, the outlet of which is located in the funnel-shaped ut 14 of the measuring chamber 5. A conical valve 15 with through holes 16 is placed above the funnel-shaped thickening 14, connected to the top by a traction element 17 passing through the opening 7 with a dynamometer 18 having a scale of 19 batches of milk, and from the bottom by means of a rigid link 20 connected with a capacity of 13, which has a drain pipe 21 in the form of a siphon. The device works as follows. Under the action of vacuum, the milk enters from the milking machine through pipe 4 into the receiving chamber 1 and through pipe 6 into the container 13. Under the force of the gravity of the milk powder the container 13 is lowered and closed with its entire outer cup-shaped surface opening 9 and valve 15 the outlet of pipe 6 located in the funnel-shaped thickening 14 of the measuring chamber 5. Since the measuring chamber 5 communicates with the atmosphere of the openings 7 and 16, the air pressure in it increases, under the action of which the valve 15 and the container 13 are kept pressed until the poured portion of milk through the siphon pipe 21 is poured into the drain chamber. After the tank 13 is emptied, the air from the measuring chamber 5 is sucked through the same pipe 21. After the air pressure in the 5 gauge and the drain 8 chambers is leveled, the dynamometer 18 raise the container 13 and the valve 15 connected by a rigid connection 20 by means of the traction element 17 upwards and milk will again flow into the container 13 through the pipe 6. The pressure change in the measuring chamber 5 is transmitted through the opening 12 to the diaphragm of the sensor 10 of the counting mechanism 11. finished In the milking, the remaining part of the milk in the tank 13 is not sufficient by weight to cover the opening 13 with a capacity of 13, indicated by a dynamometer 18 on the scale 19. To drain a given volume of milk into my pipe 3, manually stretch the spring of the dynamometer 18 and block the outlet 15 of the outlet 6 with valve 15, and with a capacity of 13 - a hole 9. A container 13 with a valve 15 can be suspended not only from the dynamometer but also from the hinged arm of the lever, the free arm of which is balanced by the corresponding weight. The proposed milk counter provides the necessary accuracy in determining the amount of milk produced.
