Description

The invention relates to devices for metering milk in milking plants and can be used when accounting for milk on livestock farms.

Known devices for metering milk, including a metering rotor installed in the housing, a receiving chamber, a float, a drive motor, a counting mechanism (see, for example, AS USSR No. 351507. Group milk meter. Maryakhin F.G., Radko V. A., Dymshits I.A.).

The disadvantage of this device is its complexity, the need to connect to the mains, high capital and operating costs.

Closest to this invention in technical essence is the "Group accounting system of milk for milking installations." See, for example, RF Patent No. 2208311. Maryakhin F.G., Uchevatkin A.I., Korshunov B.P., Orlov A.A. This device consists of a housing, inlet and outlet pipes, a dividing cone, a measuring cup, a measuring scale, a chamber, a branch pipe, a tube with a vertical slot. The disadvantage of this device is the high capital and operating costs, the complexity of flushing, low accuracy.

The task of the invention is to reduce capital and operating costs for group accounting of milk, simplify washing, increase accuracy.

The above technical result is achieved by the fact that the dividing cone is located upward on the bottom of the housing, and a chamber with an opening in the bottom is installed coaxially with it in the housing with the formation of an annular gap, so that it forms a calibrated annular hole with the surface of the dividing cone, and to the bottom a measuring cup with a measuring scale applied on it is attached to the bottom, and the lower part of the measuring cup and the central part of the body are connected by a branch pipe fixed to the bottom of the case, and in the dividing cone, in its extreme part, a pipe is vertically placed with a calibrated vertical slot located in its wall facing the top of the cone, connecting the space above and below the dividing cone, and the lower edge of the slot made in the upper part of the pipe coincides with the conical surface of the dividing cone, and in the lower part of the pipe an air valve is installed, and on the lower part of the cylindrical wall of the housing the outlet pipe is strengthened, and on the upper part of the side wall of the measuring station an air valve is strengthened, and on the side walls in the upper cylindrical part of the chamber under the inlet pipe there is a container with an axial hole in the bottom, above which on the axes there is a rotary tray having two symmetrical compartments separated by a wall, each compartment being under the inlet pipe in extreme positions limited by stops.

The invention is illustrated by the figure, which shows a General view of the device for group accounting of flows of milk and other agricultural products in vacuum pipelines.

A device for group accounting of the flows of milk and other agricultural products in vacuum pipelines contains an inlet 1 and an outlet 2 nozzles, a dividing cone 3, a measuring cup 4, a measuring scale 5, a chamber 6, a housing 7, an outlet tube 8, a tube with a vertical slot 9, and the dividing cone 3 is located on the bottom of the housing 7 with its top upward, and a chamber 6 is installed coaxially with it in the housing 7 to form an annular gap, with an opening in the bottom so that it forms a gauge with the surface of the dividing cone 3 an annular hole, and a measuring cup 4 is attached to the bottom of the housing 7 with a measuring scale 5 applied thereon, the lower part of the measuring cup 4 and the central part of the housing 7 being connected by a branch pipe 8 fixed to the bottom of the housing 7, and in the dividing cone 3, in its extreme part, a pipe is vertically placed with a vertical slot 9 located in its wall facing the apex of the cone, connecting the space above and below the dividing cone 3, the lower edge of the slot made in the upper part of the pipe 9 in its the lower part will coincide with the conical surface of the dividing cone 3, and an air valve 10 is installed in the lower part of the pipe 9, and on the lower part of the cylindrical wall of the housing 7 the outlet pipe 2 is fixed, and on the upper part of the side wall of the measuring cup 4 the air valve 11 is fixed, and on side walls in the upper cylindrical part of the chamber 6 under the inlet 1 are reinforced with a container 12 with an axial hole 13 in the bottom, above which on the axes there is a rotary tray 14 having two symmetric compartments separated by a wall, m each compartment is located under the inlet pipe 1 in extreme positions, limited by stops.

A device for group accounting of milk flows at milking installations in vacuum pipelines works as follows. The milk-air mixture from the vacuum milk line enters the housing 7 and then into the chamber 6. The milk component of the milk-air mixture, passing through a calibrated annular hole between the lower opening of the chamber 6 and the conical surface of the dividing cone 3, spreads over its surface in the form of a film under the influence of surface tension. The estimated part of the milk, separated by a tube with a vertical slot 9, through an open air valve 10 enters the measuring cup 4 and accumulates at its bottom. The rest of the milk, flowing down the conical surface of the dividing cone 3, accumulates at the bottom of the housing 7 and then through the outlet pipe 2 follows the milk line of the milking unit.

The air component of the milk-air mixture follows through the annular gap between the cylindrical walls of the housing 7 and chamber 6 and then, along with the milk, flows into the milk pipe of the milking unit through the outlet pipe 2. The readings are taken according to the milk level in the measuring cup 4 on the scale 5. When the milk level rises, the air leaves the measuring cup 4 through the valve 10 and the pipe with a vertical slot 9.

After taking the measurements manually, valve 11 opens, while atmospheric air enters the evacuated measuring cup 4 and closes the valve 10. The pressure in the cup 4 rises, and milk is “squeezed” through the outlet pipe 8 into the housing 7 and then removed from the device through the outlet pipe 2 together with the air of the milk-air mixture.

To increase the accuracy of the device at low values of milk flows, when the milk “film” becomes unstable and the division ratio of the milk film begins to be violated, a container 12 with an axial hole 13 in the bottom is mounted in the chamber 6, over which an axial tray 14 is mounted on the axes, in the compartments of which milk is pre-accumulated and then alternately enters the chamber 6 "pulses" through the axial hole 13.

The proposed device for group accounting of milk flows at milking installations in vacuum pipelines is more accurate and structurally simpler than the prototype and has a lower cost. Maintenance costs are also lower due to easier disassembly and better flushing.
