Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to teat cups.

Known teat Cup, comprising a housing and an elastic ring installed in the upper part of the housing 13.

However, during the sucking stroke, the teat cup crawls onto the nipple during the milking process.

A milking cup is also known, including a liner, a nipple rubber, an interstitial chamber and a lactating stimulator, made in the form of a spring-loaded valve with a housing, the cavity of which is in communication with the interstitial chamber and the atmosphere 2.

However, the known glass does not sufficiently stimulate the milk flow and does not eliminate the crawling of the teat cup on the nipple.

The purpose of the invention is to improve the styling of the milk flow and reduce the creeping of the teat cup onto the teat.

The goal is achieved by the fact that the valve of the stimulator is located inside the body, which is rigidly fixed on the side of the sleeve of the glass and equipped with a shock-absorbing sealing washers.

In the second embodiment of the teat cup, the goal is achieved by the fact that the stimulator valve is complete in the form of a ring and installed inside the body, which is equipped with shock-absorbing washers and rigidly fixed on the sleeve of the glass, with the body with the said washers and valve located on the sleeve coaxially her.

FIG. 1 schematically shows a teat cup, tact suck; in fig. 2 shows a second embodiment of the teat cup, the compression stroke.

Milking cup includes (Fig. 1)

20 liner 1, nipple rubber 2, interstitial 3 and underflow 4 chambers. On ; the side of the sleeve is rigidly fixed to the stimulator of the milk flow, fulfilled in

view of housing 5 with valve 6 spring loaded 7. In case 5, damping-sealing nuts 8 are installed. In the upper part, cavity 9 of housing 5 is in communication with the interwall wall 3 of the cup through channel 10, and in the lower channel 11 with atmosphere.

In the second embodiment of the teat cup (Fig. 2), the body 5 of the stimulator together with the valve 6 and the damping-sealing washers 8 is located on the sleeve 1 coaxial to it, the valve 6 being designed as a ring.

When operating during the suction stroke, a vacuum is created in the pre-drip 4 and inter-wall 3 chambers, which through the channel 10 penetrates the cavity 9 of the housing 5 of the stimulator. Under the action of atmospheric pressure acting through channel 11 on valve 6, the latter will take an extreme position and block channel 10, thus reducing air flow. The spring 7 of this is compressed, thereby reducing the successful loads of the valve 6 on the sleeve 1I. During the compression stroke in the pre-sweep chambers 4 there is a negative pressure, and the mesential chamber 3 has an atmospheric pressure, while under the action of its own weight and elasticity of the spring 7, the valve 6 falls hitting the damping-sealing washer 8, pushes the teat cup down, lowers it ie on the nipple. The valve pushes .6 down, reducing the teat cup's creep on the nipple, at the same time pulling the teat off the udder, and the milk flow and the massage effect of the teat cup.

Similarly, the operation of the teat cup in the second. option.

The use of the invention will reduce the weight of the suspension.

milking machine, improve the stimulating effect and reduce the crawling of the teat cup on the teat of the udder.

Claims (2)

1. A teat cup, including a liner, a nipple rubber, an interstitial chamber and a lactation stimulator, made in the form of a spring-loaded valve with a housing whose cavity communicates with the interstitial chamber and atmosphere, characterized in that, in order to improve the stimulation of the milk flow and reduce the crawling of the milking cups on the nipple, the valve of the stimulator is located inside the body, which is rigidly fixed on the side of the sleeve of the glass and is equipped with shock-sealing washers. 2, The teat cup, including the liner, the nipple rubber, the interstitial chamber and the lactation stimulator, is made in the form of a cushioned valve with a housing, the cavity of which is connected to the interstitial chamber and the atmosphere, in order to improve the stimulation of the lactation and reduce the crawl. , teat cup on the nipple, the valve of the stimulator torus is complete in the form of a ring and is installed inside the housing, which is provided with damping-sealing washers and is rigidly fixed on the sleeve of the glass, the housing with said washers and valve being located on the sleeve coaxially to it.
