Description

 The invention relates to devices for metering milk in a stream during milking in a milk pipe.

 Known devices for metering milk (ed. St. USSR N 454877, class A 01 J 7/00; US patent N 3831011, class 255-151), the disadvantages of which are the insufficient accuracy of the metering of milk and the need to connect devices to the mains.

 Closest to the technical nature of the present invention is a milk meter (ed. St. USSR N 231964, class A 01 J 7/00, 1967), comprising a housing, a milk flow divider, a receiving chamber with inlet and outlet pipes, measuring gauge and calibrated hole.

 The disadvantage of the milk meter is that in the presence of a number of receiving holes it is difficult to evenly divide the flows at low flow rates, which leads to errors in the readings of the device.

 The objective of the invention is to improve the accuracy and improve the washability of the device.

 As a result of the use of the invention, the accuracy and washability of the device is improved by improving the streamlining of its internal surfaces with milk and washing liquid, eliminating stagnant zones, and also increasing the stability of the division of the milk flow at any current flow values.

 The above technical results are achieved by the fact that a tube with a calibrated hole is added to the known device, connecting the upper part of the measuring scale with the upper part of the receiving chamber, the calibrated hole being located in the upper part of the tube on a cylindrical surface, the sides of the hole are limited by planes passing through the outer and the inner cylindrical surfaces of the tube, the lower edge of the hole is above the bottom of the receiving chamber, and the upper edge is open The hole is located below or coincides with the upper end of the tube. The inlet pipe in the upper part is made in the form of a centering pipe, and the milk flow divider is made in the form of a dividing cone and, screwed on its top, a screw-type screw-type device that closes the milk flow. The screw-shaped device is located coaxially in the centering pipe and is in contact with its inner cylindrical surface, and the upper part of the centering pipe expands, forming a concentric cavity with the surface of the cone.

 The essence of the device for individual accounting of milk is illustrated in the drawing.

 The device comprises a housing 1; a milk flow divider, including a dividing cone 2, with a screw-type screw device 3 fixed on its top; a receiving chamber 4 with inlet 5 and outlet 6 nozzles; measuring scale 7; a tube 8 with a calibrated hole 9, connecting the upper part of the measuring scale 7 with the upper part of the receiving chamber 4; the supply pipe 5 in the upper part is made in the form of a centering pipe 10, the upper part of which expands, forming a concentric cavity with the surface of the cone.

 The device operates as follows.

 The milk flow from the milking machine through the inlet pipe 5, placed on the housing 1, enters the centering pipe 10 and to the screw-shaped device 3, which "twists" the stream, evenly distributing it on the surface of the dividing cone 2. The surface tension turns the milk layer into a kind of elastic film , which is fed to the expanding part of the dividing cone 2, and part of the milk, proportional to the angle of coverage, is fed into the receiving hole 9 and flows through the tube 8 into the measuring scale 7, and the air from the scale 7 gives into the housing 1 and from there through the outlet pipe 6 enters the milk line and to the vacuum pump. The location of the hole 9 on the tube 8, made, for example, of metal, allows to reduce the maximum diameter of the dividing cone 2 and makes the design more technological. The device for individual milk accounting can be hung by a bracket.
