Abstract

This invention relates to agriculture. The purpose of the invention is to improve performance. The device comprises a transparent case, a receiving chamber 1 with nozzles, communicated with an overflow chamber 6 connected by a calibrated channel 7 to the atmosphere. In the chamber 6 is a screen made in the form of a sleeve. The sleeve is turned upside down and has a vertical guide 13 with a through hole 14 communicated with the channel 7. The channel has a seat blocked by the bottom of the sleeve. The sleeve consists of two coaxially arranged cylinders, the inner one of which is perforated in its lower part.

Description

The invention relates to agriculture, in particular to devices for the automatic selection of the first portions of milk.

The purpose of the invention is to improve the performance of the device for the automatic selection of the first portions of milk.

The drawing shows a device for automatically selecting the first portions of milk.

The device contains a receiving chamber 1 with an inlet 2 and an outlet 3 with nozzles connected to the screen 4 and the float 5 bypass chamber 6 connected by a calibrated channel 7 to the atmosphere, and the drain channel 8 and the check valve 9 to the milk collection section 10, with - m screen 4 is made in the form of a sleeve 11, forming with a locking element 12 installed at its end a float 5 movably mounted on a guide 13 installed in a transparent case, having a through axial bore 14, the entrance of which is connected to a calibrated channel 7, and out A saddle 15 is installed, having the possibility of contacting with the locking element 12. Moreover, the sleeve 11 is removed from two coaxially arranged cylinders, the inner 16 is perforated with radial holes 17, and the outer 18 is mounted movably with the possibility of blocking the openings 17 in series.

The level of milk in the bypass chamber 1 is controlled by changing the outer cylinder 18 relative to the holes 17 on the inner cylinder 16. The working volume of the float 5 and, consequently, the level of milk at which the pop pops 1 starts to float.

The device works as follows.

The nozzles 2 and 3 are inserted into the break of the milk hose. When the milking machine is connected to the source of vacuum and the udder of the animal in the receiving chamber 1, a vacuum is created, and milk flows through the inlet pipe 2 into the overflow chamber 6.

As it is filled and milk reaches a level at which pop pops up

5, the latter overlaps with a locking element 12 an empowered chamber 1. Milk follows an inlet nozzle 2, a receiving chamber 1, an outlet nozzle 3 and further into the milk conduit, a bypass chamber 6. Thus, the first portion of milk of a predetermined volume. ma is cut off from the stream. After the float 5 emerges, the bypass chamber 6 is izobiruyus from a vacuum source, and through the calibrated channel 7 through the axial through hole 14, made in the guide 13, whose entrance is already open, air enters, and the pressure gradually rises to atmospheric, the check valve 9 under the weight the milk is opened and the milk flows from the overflow chamber 6 through the drain channel 8 to the milk collection section 10.

The transparent body of the bypass chamber 6 allows for visual control of the first portion of milk against the background of the screen 4.

Claims (2)

1. A device for automatic selection of the first portions of milk, containing a transparent body, a receiving chamber with inlet and outlet pipes, communicating with a screen for visual control of milk and a float bypass chamber connected with a calibrated channel to the atmosphere, and a drain channel with the milk section, characterized in that, in order to keep its performance characteristics, the screen is made in the form of an upwardly facing sleeve, inside which there is a vertical guide fixed to the housing; with a through axial hole, which is communicated with the channel and has a valve seat arranged to cooperate with the bottom of the liner. 2. The device according to claim 1, characterized in that the sleeve is made in the form of two axially arranged coaxial cylinders which are installed with the possibility of displacement relative to each other, and the lower part of the side wall of the inner cylinder is perforated.
