Description

one

The invention relates to agriculture, households, in particular to milk meters.

A known milk counter, including vacuumized receiving and measuring chambers, is connected by an overflow tube, which is blocked by a float LlJ.

The known milk meter does not provide the necessary accuracy for measuring the amount of milk during milking.

. A milk counter is also known, which contains an evacuated receiving chamber and an overflow opening connected to it, which is covered by a bell-shaped float, a measuring chamber having a drain channel and an air channel 1.2 J. communicated with the atmosphere.

This milk meter also does not provide the necessary accuracy in measuring the amount of milk produced.

The purpose of the invention is to improve the measurement accuracy and operational reliability of the milk counter.

The goal is achieved by the fact that the Keuviepa gauge is equipped with a vertical rod in which the said air channel is located, and the float is equipped with a valve for closing the air channel made in the tube telescopically connected to the float, and in the float there is an opening , by means of which the cavity of the float communicates with the part of the measuring chamber located around the bypass hole.

The lower end of the tube is located above the lower end of the float.

ten

The drain channel is equipped with a valve.

FIG. 1 shows a schematic counter of a milk; FIG. 2 shows section A-A in FIG. one.

The milk meter contains a reception

15 chamber 1 and an overflow opening 2 connected to it, which is blocked by a bell-shaped float 3, a measuring chamber 4 having a drain channel 5

20 and communicated with the atmosphere by the air channel 6 located in the vertical rod 7. The float 3 is equipped with a valve, made in the form of a tube 8, which is telescopically connected

25 with the float 3, and interacts with the rod 7. The additional channel 9 is made in the rod 7, and the holes 10 are made in the float, through which its cavity communicates with the part of the metering chamber located.

around the bypass hole 2. The lower end of the tube 8 is located above the lower end of the float 3. The drain channel 5 has a valve 11, the measuring chamber 4 is connected to a sensing element 12 connected to a recording device 13. The power supply of the sensing element 12 is carried out either from a vacuum line 14 , or from the dairy line 15. Receiver KciMepa 1 is equipped with a pipe 16, and the meter drain chamber 17 has a pipe 18 connected to the dairy highway 15.

The milk meter works as follows.

When vacuum is applied, vacuum is created in chambers 1.4 and 17. Milk from a milking machine (not shown) enters through pipe 16 into chamber 1 from which through hole 2 flows into measuring chamber 4. In the process of filling measuring chamber 4, the level of milk reaches the bottom the end of the float 3 and then fills its cavity, while the air from the float is displaced by the channel 9 and through the holes 10 into the upper part of the metering chamber 4, from which it is forced into the receiving chamber 1. With further filling of the metering chamber 4, the float 3 moves upwards and valve performed In the form of a tube 8, opens the channel 6. At the same time, the pressure rises in the cavity of the float 3, which at the same time closes the bypass hole 2. The pressure in the measuring chamber increases, the valve 11 opens and the milk is displaced through channel 5. The change in pressure in the measuring chamber 4 perceived by the sensing element 12, issuing a signal to the recording device 13. From the discharge chamber 17, the milk through the fitting 18 is sucked into the milk line 15. After discharge of the portion of milk from the drain chamber 17 into the milk line, the vacuum level in the measuring chamber re 4 is restored, float 3

is lowered, opening the access of milk from the receiving chamber 1 to the measuring chamber 4. Then the cycle repeats. The milk meter is reliable in operation and provides the necessary accuracy in measuring the amount of milk produced.
