Abstract

This invention relates to agriculture. The purpose of the invention is to simplify operation and reduce the ingress of microflora into milk. The device for sampling the first portions of milk contains an inlet section 3 with inlet 4 and outlet 5 nozzles and an overflow section 6 with a float valve 9. The nozzles 4 and 5 are coaxially positioned at the level of the aperture 10, communicating the overflow 6 and the receiving 3 section. The receiving section 3 is equipped with a rotary valve 12. One part of the latter is made more desirable than another part located on the side of the inlet 4. The bypass section 6 communicates with the milk collecting section 1 through a non-return valve 15. In the receiving section 3 there is a means of opening the float valve 9 in the form of levers. 1 h. the item of f-ly, 4 ill.

The invention relates to agriculture, in particular to a device for selecting the first portions of milk.

The purpose of the invention is to simplify operation and reduce the ingress of microflora into milk.

FIG. 1 schematically shows a device, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 — node I in FIG. 3

The device for sampling the first portions of milk contains a milk collection section 1 with a lid 2 on which the receiving section 3 is located with the inlet 4 and the outlet 5 nozzles arranged coaxially, the bypass section b formed by the lid 2 and the cylinder 7 mounted on the annular ledge 8 of the milk collection section 1 In the overflow section 6 a float valve 9 is placed. The receiving section 3 communicates with the overflow section 6 by an opening 10, in the center of which on the axis 11 there is a rotary shutter 12, one part of which is made larger than the other part of the valve. On the side of the inlet nozzle 4. The overflow section 6 is connected with the atmosphere by a calibrated orifice 13, made in the lid 2, and with the milk collection section 1, with an orifice 14, above which the check valve 15 is installed. The milk orifice 16 is connected with the atmosphere by the orifice 16. In the bypass section 6 has a means of opening the float valve 9, made in the form of levers 17 rigidly connected to the axles 18 pivotally mounted on the cover 2, and the handle 19 rigidly attached to the ends of the axes 18 located above the cover 2. For sealing the rotary valve 12 in the selection of the first portions of milk in the receiving section 3 is made the ledge 20.

The device for sampling the first portions of milk works as follows.

By connecting the device to the milk line (not shown) in the receiving section 3 and in the bypass section 6, a vacuum is created, and the flow area of the receiving section 3 is blocked by the rotary valve 12, and the hole 14, which communicates the bypass section b with the milk collecting section 1, is blocked valve 15.

The first portions of milk enter the receiving section 3, fall on the butterfly valve 12 and merge into the overflow section 6. With the filling of the overflow section 6

with milk, the float valve 9 rises and closes the opening 10, which communicates the receiving section 3 with the bypass section b, while the rotary valve 12 rotates, takes a horizontal position and does not prevent the transport of milk to the milk conduit (not shown). After the opening 10 of the float valve 9 is closed, the suction of air entering through the calibrated opening 13 into the overflow section b is stopped and the latter is set to atmospheric pressure. With the establishment of atmospheric pressure in the bypass section b, the check valve 15 under the action of the weight of the milk opens and the milk is drained into the milk collection section 1, and the float valve 9 is sucked to the hole 10 and held on to it until the end of the animal's milking.

After the animal is milked, the operator of the machine milking machine by turning the handle 19, rigidly connected with the levers 17, opens the float valve 9, pushing it away from the hole 10, as a result of which a vacuum spreads to the overflow section and the device is ready for further work.

Claims (2)

1. A device for sampling the first portions - milk, containing a receiving section with inlet and outlet nozzles, a bypass section with a float valve, communicated with a receiving section by an orifice located above the float valve and a milk collecting section, through a check valve, characterized in that simplify operation and reduce microflora in milk, inlet and outlet nozzles are located coaxially and are set at the level of the hole that informs the bypass and receiving sections, the last of which is equipped with hydrochloric valve having an axis extending through its middle and arranged in the center of said openings, wherein one part of the rotary valve is made heavier than the other part, situated on the part of the inlet pipe. 2. A device according to claim 1, characterized in that in the bypass section there is a means for opening the float valve, made in the form of a two-armed lever with a handle. t3 76 7 18 fig.Z Fmg.2 ux w Surgus
