Abstract

FIELD: mechanization of dairy cattle production.

SUBSTANCE: proposed milk counter has cylindrical housing, separating reservoir and movable measuring chamber which is connected with resistance strain gauge converter by means of rod running through bellows seal. Separating reservoir is cone-shaped in form and its branch pipe is located tangentially. Separating reservoir is provided with hydraulic seal in its lower part which is fitted with movable partition. Movable measuring chamber is parabolic in shape and is provided with escape slit in form of rectangle in its end face. In the course of milking, milk is tangentially fed to separating reservoir through inlet branch pipe; mixture of milk and air is set in motion over wall of separating reservoir. Trajectory of motion has form of spiral. Under action of centrifugal force milk and air are separated and are discharged from reservoir through discharge tube. For complete separation of air, use is made of hydraulic seal having movable partition. After separation of air, milk is fed to movable parabolic measuring chamber. Mass of chamber is recorded by means of rod with the aid of resistance strain gauge converter connected with counting unit.

EFFECT: enhanced accuracy of counting milk due to use of unit separating gas from liquid.

Description

The invention relates to the mechanization of animal husbandry.

A known liquid counter comprising a tray of two measuring chambers having a common wall, and a counting device that takes into account the number of rollovers of the tray, thereby measuring the amount of incoming liquid (SU 1335210 A1 07.09.87, BI No. 33).

A known device for recording the intensity of milk transfer, including a measuring capacitance, a valve and permanent magnets with a solenoid (SU 1646525 A1 07.05.91, BI No. 17).

Closest to the invention is a slit flow meter with a movable measuring chamber, including a segmented separating tank, a movable measuring chamber and a strain gauge transducer (Kremlevsky P.P. Flow meters and quantity counters. L .: Mashinostroenie, 1989, p. 226-229).

This device is designed to measure the flow of gas-liquid mixtures. However, it does not provide a sufficiently good separation of gas from a liquid, which reduces the accuracy of accounting for liquid flow.

The objective of the invention is to increase the accuracy of milk accounting. This is achieved by using a more advanced device for separating gas from liquid.

The invention will be clear from the following description and the attached drawings.

Figure 1 shows the design of the milk meter, General view; figure 2 is a cross section of a milk meter; figure 3 - the device of the movable partition with a control handle.

The milk counter (figure 1) consists of a cylindrical body 1, the input part in the form of a separating tank 2 conical shape and a movable measuring chamber 3 of a parabolic shape. The latter by means of a rod 4 passing through a bellows seal 5 is connected to a strain gauge transducer 6.

The separating tank 2 is cone-shaped and in the lower part is equipped with a hydraulic shutter with a movable partition 7. A movable measuring chamber 3 is parabolic in shape, in the end part of which there is an expiration slot 8 in the form of a rectangle (figure 2). The shape of the chamber and the slit provides a linear relationship between the mass flow rate and the mass of milk in the chamber. The inlet pipe 9 is located tangentially to the wall of the separating tank 2 conical shape. In the upper part of the separating tank 2, a gas outlet tube 10 is installed. A handle 11 is provided for controlling the partition 7 (Fig. 3). The measuring chamber 3 of a parabolic shape is mounted on a suspension support 12 (figure 2). An outlet pipe 13 is installed in the lower part of the separating vessel 2 of the conical shape. To minimize the measurement error associated with the action of the jet on the movable chamber, the outlet pipe 13 of the separating vessel 2 of the conical shape is installed above the hanging support 12. The outlet pipe 14 is installed in the lower part of the housing 1. The counting device 15 is equipped with a sensor in the form of a strain gauge Converter 6.

The milk meter (see figure 1) works as follows.

During milking, milk through the inlet pipe 9 is tangentially fed into the separating tank 2 in a conical shape, as a result of which the mixture of milk and air is moved along the wall of the separating tank 2. The trajectory has a spiral shape. The action of centrifugal force separates milk and air, which through the outlet tube 10 is removed from the tank. For a more complete separation of the air, a hydraulic shutter with a movable partition 7 is used, which is turned with the handle 11 around the axis when flushing the device.

After air separation, milk is fed into a movable measuring chamber 3 of a parabolic shape located on the suspension support 12 through the outlet pipe 13 located above the suspension support 12, thereby minimizing the measurement error. Milk is sent to a rectangular slot 8 through a measuring chamber 3 of parabolic shape and after mixing with air coming from the tube 10, then to the outlet pipe 14. The mass of the chamber 3 of parabolic shape using a rod 4 passing through a bellows seal 5, is recorded by a strain gauge transducer 6, associated with the counting device 15.
