Description

The invention relates to agriculture, in particular to teat cups.

The purpose of the invention is to improve the milking process by reducing the return flow of milk.

The drawing shows a teat cup, a general view.

The teat Cup includes a housing 1, an elastic spiral tube 2, the lower end of which is fixed in the opening 3 of the housing 1 by a clip 4 with an internal opening 5 and communicated by a nozzle 6, in the inlet of which a check valve 7 is installed with a pulsator variable vacuum chamber 8. tube 9, rifle coaxially with housing 1 inside spiral tube 2, the lower part of the additional elastic tube 9 is connected to the hammer 10. The upper end of the spiral tube is equipped with an additional nipple 1, Otori communicates with the camera alternating vacuum pulsator. In the inlet pipe 11 is installed check valve 12.

The teat cup works as follows.

A positive pressure is supplied to the spiral tube 2 through the pipe 11. The expanded, elastic tube 2 compresses the nipple, with compression going from top to bottom, i.e. in the direction of the nipple sphincter. A pressure equal to the pressure in the milk outlet 10 is supplied to the spiral tube 2 through the pipe 6.

The tube 2 occupies its original position, and this process goes from the bottom up. Thus, under transient conditions in a teat cup, the pressure gradient is always directed towards the nipple sphincter. This makes it possible to reduce unwanted return currents of milk, leading to animal disease with mastitis. Check valves 7 and 12 are required to supply a certain pressure to the lower and upper ends of the elastic tube. The elasticity of the spiral tube 2 is greater than the elasticity of the additional tube 9.

Claims (2)

1. The drinking cup, the supporting body and the elastic tube spirally arranged in it, the lower end of which is fixed in the wall of the body and communicated through the nipple with the variable vacuum chamber, the suction cups and the .1 diversion chamber, characterized in that reducing the reverse currents of milk; the upper end of the elastic tube is provided with an additional pipe which communicates with the pulsator's alternating vacuum chamber, while the inlet ports of the pipes are equipped with check valves. 2. A glass bottle according to claim 1, characterized in that it is provided with an additional elastic tube which is installed coaxially with the body inside the spiral tube.
