Abstract

This invention relates to agriculture. The purpose of the invention is to improve the accuracy of milk accounting by eliminating water hammer in the system. The device has a housing 1 with a receiving 2 and measuring 3 cameras, as well as a drainage chamber 7. The measuring chamber 3 is provided with interconnected by means of a connecting skirt 8 spheres 9 and 10. The upper sphere 9 is fixed on the nozzle 11. The axis of the connecting skirt 8 is offset relative to the bottom axis spheres 10. A vertical tube 12 is installed in the receiving chamber 2. Milk enters the receiving chamber 2 and under the action of gravity forces is discharged into the measuring chamber 3 through spheres 9 and 10.

Description

The invention relates to agriculture, in particular, to devices for measuring milk production.

The purpose of the invention is to improve the accuracy of milk accounting by eliminating water hammer in the system.

The drawing schematically shows the proposed device, a General view. The milk counting device comprises a housing 1 with a receiving 2 and three measuring chambers separated by a partition 4. The receiving chamber 2 has an inlet 5, and a measuring 3 output nozzle 6 is connected to the discharge chamber 7. Measuring chamber 3 is connected with each other by means of a connecting skirt 8 spheres 9 and 10. The upper sphere 10 is fixed on the nozzle 11. The axis of the connecting skirt 8 is displaced relative to the axis of the lower sphere 10. Vertical tube 12 is installed in the receiving chamber 2.

The device works as follows.

Under the action of vacuum, milk from a milking machine (not shown) through the inlet 5 enters the receiving chamber 2 and under the action of gravity forces merges into the measuring chamber 3 through spheres 9 and 10 and further along the outlet 6 enters under the action of vacuum into the counting device ( not shown) calm and uniform stream. Such a laminar flow of milk from the receiving chamber 2 into the measuring chamber is facilitated by the tube 12, which is located in the receiving kayer 2, which maintains an equal vacuum in the chambers, and the flow is equalized by means of a water hammer in the nozzle 11, skirt 8, upper 9 and lower 10 asymmetric spheres in co

Due to the change and random rotation of the streams, energy is expended on the internal molecular structure. The speed of movement of the fluid flowing out of the discharge pipe under the action of gravitational forces is calculated by the formula

V, uV2gH where p, is the flow coefficient depending on

viscosity (0.61 .. 0.24); g — acceleration of the force of gravity, m / s2; N- height from the drain pipe to

liquid level, m

This formula is applicable when the value of H is constant. At the same time, the speed of milk under the action of vacuum exceeds the speed of milk flowing from the drain pipe under the action of gravity, which is compensated by the living section of pipe 11, skirt 8 and the total volume of asymmetric spheres 9 and 10, corresponding to at least half the volume of the measuring chamber 3.
