Abstract

This invention relates to agriculture. The aim of the invention is to increase the efficiency of monitoring the size of the closure of nipple resilience and its tightness. The device comprises a connecting pipe 1 connected to a vacuum source and a vacuum gauge 2 mounted on the vacuum wire 3, which communicates with the suction cup 4 of the teat cup. An artificial teat is inserted into the barrel. At this time, the membrane 10 bends and, according to the indicator 11, the amount of rubber closing is evaluated.

Description

The invention relates to the rural: | state, in particular to devices for diagnosing nipple rubber.

The aim of the invention is to increase the effectiveness of controlling the size of the nipple gum closure and its tightness.

The drawing shows a general diagram of the Device.

The device contains a nozzle 1 connected to a vacuum source, a vacuum meter 2 located on a vacuum wire 3 connected to a teat chamber 4 milking cup, an artificial teat 5 with a longitudinal through channel 6 and inserting inside a teat rubber 7, chamber 8 an elastic non-retractable material filled with liquid, a perforated tube 9 attached to the lower part of the channel 6 and immersed in the liquid in the chamber 8, the membrane 10 with an indicator 11 located in the upper expansion cavity of the channel 6, scale 12, fixed nnuyu artificial nipple. The inlet pipe 1 is equipped with a two-stage valve 13 for disconnecting the vacuum source from the source. Valve stem 14 has a membrane 15 that separates the vacuum system of the device from the atmosphere of the upper cavity of the valve. In addition, the valve is equipped with a spring 16 with an emphasis 17 and a saddle 18, located on the branch pipe 1.

The device works in the same way.

When connecting the nozzle 1 to the vacuum source, air is sucked out of the sub-junction chamber 4, the nipple of the rubber 7 is closed due to the pressure difference on the walls and compresses the chamber 8,

displaces the fluid from it through the tube 9 into the expansion cavity of the longitudinal channel 6 The fluid in the cavity bends the membrane 10 and moves the pointer 11 up along the scale 12.

When the nominal vacuum in the underflow chamber 4 is reached, the membrane 15, due to the pressure difference, overcomes the resistance of the spring 16, bends downwards and lowers the valve 13 into the saddle 18, disconnecting the device from the vacuum source. one

Based on the indications of the indicator 11, the value of the closing of the nipple rubber is estimated, and based on the indications of the vacuum gauge and time, the fall time of the vacuum is determined by which the tightness of the nipple rubber is estimated.
