Abstract

This invention relates to agriculture. The purpose of the invention is to simplify the design of the device and increase the effectiveness of the massage. The device for pneumo-mechanical massage contains a bell 1, made of elastic material, at the junction of wall 2 and bottom 3, there is a stiffening ring 4 and an orifice 6, the ratio of which to the area of the bottom of the massage bell 1 is 1: (12000-12500). A vacuum is applied through the orifice 6, the bell 1 is pressed against the udder. The vacuum pulls down the outflow, performs a pneumomechanical effect on all parts of the udder at the same time, the side walls 2 and the bottom 3 of the bell squeeze out the outflow, performed a mechanical action. When the vacuum supply is stopped, the withdrawal returns to its original position, the walls and bottom occupy the initial position. 3 il.

The invention relates to devices for massage of the udder of farm animals and can be used in breeding yards of dairy complexes.

The aim of the invention is to simplify the design of the device, and increase the effectiveness of the massage of the udder of animals due to a uniform massage of all parts of the udder.

Fig. 1 shows a diagram of a device for the pneumomechanical massage of an udder of farm animals; 2 shows a general scheme of the impact of the bell on the pump during a massage, the work cycle; on fig.Z - the same tact rest.

The device for pneumatic mechanical massage of the udder is a cup-shaped bell 1, having walls 2 and bottom 3, which are made of elastic material (for example rubber 8-12 mm thick), at the junction of the wall and the bottom of the massage bell there is a ring of rigidity 4 for better skin contact animal, and at the ends of the bell wall there is a sealing element 5, at the junction of the bottom into the wall (on the ring of rigidity) there is an orifice 6, which is connected to a variable vacuum source 7.

The device works as follows.

ABOUT

u o o o u ate

The operator conducts sanitization of the animal's udder, a vacuum is introduced into the interior of the massage bell through a choke hole B, a bowl-shaped bell is brought under the pin and pressed to it. The bell is held on the udder due to negative pressure and the presence of a seal.

During the working stroke (Fig. 2), a combined effect is carried out on the vym: the vacuum retracts down to the bottom, performs a pneumomechanical effect on all parts of the udder, while the side walls 2 and the bottom 3 of the bell are crimping the pin, performed the mechanical action.

When the vacuum supply is stopped during the operation of the pulsator, the withdrawal returns to its original position, the walls and the bottom of the massager occupy the initial position (Fig. 3).

The enhancement of the mechanical effect in the proposed massage device occurs due to fluctuations in the level of vacuum within certain limits, which provides .1

size of the throttle hole, the ratio of the cross section of which to the area of the bottom of the massage bell is in the range 1: (12000-12500).
