Abstract

This invention relates to agriculture. The purpose of the invention is to simplify the design of the device. The milk sampling device contains a measuring chamber 1 with a valve 2 and a dosing chamber 4 with a float 3. In the side wall of the measuring chamber 1 there is a branch pipe 7, on which an elastic branch pipe 8 is installed. The thin wall of the elastic branch pipe 8 is made in the form of a membrane. The sampled sample accumulates in the menuzer 9. By displacing the elastic pipe 8, a gap is established between the membrane and the end of the pipe 7, thereby determining the volume of the sample being collected. The device is disconnected from the dispenser by moving the elastic nozzle 8 until the diaphragm channel 7 closes completely with the membrane. When vacuum is applied to the measuring chamber 1, the diaphragm 8 bends and closes the nozzle channel 7. When the milk is drained from chamber 1, atmospheric pressure flows into it, the membrane of the nozzle 8 takes its original position and the sample is taken. 1 il.

Description

BCUOT the gap between the membrane and the end of the nozzle 7, thereby determining the volume of the sample collected. The device is disconnected from the dispenser by moving the elastic nozzle 8 until the diaphragm channel 7 closes completely with the membrane. When vacuum is applied to the measuring chamber 1, the diaphragm 8 bends and closes the nozzle channel 7. When the milk is drained from chamber 1, atmospheric pressure flows into it, the membrane of the nozzle 8 takes its original position and the sample is taken. 1 il.

The invention relates to agriculture, in particular, to devices for sampling milk when milking cows with milk-conducting installations, for example ADM-8.

The purpose of the invention is to simplify the design.

The drawing shows a device for sampling milk.

The device contains a measuring chamber 1, a valve 2, a float 3 placed in the dosing chamber 4. The valve 2 is fixed on the tube 5 with a calibrated orifice 6. In the side wall of the metering chamber 1 there is a branch pipe 7, on which an elastic branch 8 is fixed in the hole a removable measuring scale 9 is installed. The thin wall of the elastic nozzle 8 is made in the form of a membrane.

The milk sampling device operates as follows.

On the pipe 7, the offset of the pipe 8 establishes a fixed gap between its side wall and the end of the pipe 7, corresponding to the required size of the milk sample. Under the elastic pipe 8, a scale 9 is placed. With the vacuum applied to the dosing chamber 4, the membrane of the elastic pipe 8 is sucked to the end of the pipe 7 and blocks its outlet opening.

During milking, the milk flows from the milk line to the dosing chamber 1 and accumulates in the dosing chamber 4. The float 3 pops up the tube 5 and the valve 2 moves upwards. When the measuring chamber I is completely filled through the calibrated orifice (± and tube 5, the atmosphere enters it and milk is pumped through the milk line. At the same time, under the action of atmospheric pressure, the membrane of the flexible nozzle 8 is straightened and into the gap formed, the milk flows into the borehole 9 at the free flow rate the time of decline of the level of milk in the measuring chamber 1 below the channel of the nozzle 7.

With the emptying of the measuring chamber 1 in

a vacuum is applied thereto and the membrane of the flexible nozzle 8 again disconnects the channel of the nozzle 7 from the atmosphere. Float 3 is lowered and the process of taking the next milk sample is

from the dispenser chamber is repeated.

The device is disconnected from the dispenser by moving the elastic nozzle 8 until the diaphragm channel 7 closes the diaphragm completely. The volume of sampling is controlled by the size of the membrane gap of the elastic nozzle 8 to the nozzle 7 end.
