Description

The invention relates to agriculture, in particular to dairy farming.

A device for massage of the udder of cattle, including a massage bell with a shell, equipment for attaching, a source of variable pressure [1].

The disadvantages of the device are the inability to regulate the efforts of the variable pressure during massage of the udder and the lack of a safety valve and a filter that protects the air pipes from contamination.

A device is known that includes a massage bell in the form of a corrugated bell, in the lower part of which there are protruding massagers in the form of elastic rods [2] (prototype).

The disadvantages of this device is that the removable nozzle is made in the form of a single bell, this makes it difficult to compress the nozzle in the process of pulsation of vacuum pressure.

Common disadvantages of the above devices are their limited functionality, namely, that the installed removable nozzles for the main massage have an insufficient effect on the udder.

The objective of the invention is to increase the effectiveness of massage effects on the udder during mechanical massage.

The technical result of the invention is that in the inventive device, the removable nozzle is made in the form of a corrugated bell, in the lower part of which there are protruding massagers from elastic rods in the form of fungi, which are equipped with movable disks.

Common signs of the claimed device with the known [1,2], is the presence of a massage bell, shells and handles, filter, valve and a source of variable vacuum.

Distinctive features from the known devices [1,2] are that in the proposed device for improving the process of mechanical massage, in the lower part of the corrugated bell there are protruding massagers from elastic rods in the form of fungi, which are equipped with movable disks.

The invention is illustrated in the drawings.

In FIG. 2 - the main massager, a longitudinal section;

In FIG. 3 - main massager, fragment;

In FIG. 4 - main massager, cross section;

In FIG. 6 - removable nozzles, top view.

The device for massage of the udder of cattle consists of a main massager 1, a removable nozzle 2 in the form of a corrugated bell, a safety valve 3 and a variable vacuum source.

The main massager consists of a massage bell 4, a hollow handle 5, an elastic shell 6. In the wall of the massage bell 4 there is an opening 7 communicating with the cavity of the handle 5. In the cavity of the handle 5 there is a working valve 8, consisting of a socket 9, a pointed rod 10 and a spring 11. The rod 10 has a longitudinal channel 12, one end not reaching the base of the tip, and the other end communicating with the atmosphere. The position of the rod 10 is fixed by a stopper 13 with a return spring 14-

The removable nozzle 2 in the form of a corrugated bell in the lower part has a cross-shaped platform 15 with protruding massagers 16 of elastic rods made in the form of fungi, which are equipped with movable disks 23.

The variable vacuum source includes a pipe 18, dispensing valves 19, a pulsator 20, a filter 21 and a hose 22.

The device operates as follows. e

The pump creates a constant vacuum in the pipe 18, which, through the dispensing valve 19 (when it is open), enters the pulsator 20, where it is converted into an alternating one, with a pulsation frequency of 0.8-1.5 Hz. The pulses of an alternating vacuum through a hose 22 enter the internal cavity of the main massager 1 through the cavity of the handle 5, the operating valve 8, hole 7 and cause the udder to deform.

With local mechanical massage, the main massager 1 by the handle 5, with the valve 8 closed, is brought to the udder of the animal. After that, open the valve 8 and the main massager 1 is attached to the massaged part of the udder. The magnitude of the force of exposure to an alternating vacuum is changed by adjusting the vacuum flow rate with a valve 8, the position of which is fixed by the stopper 13. During massage, the main massager 1 is moved to the udder sections. To do this, close valve 8, channel 12 on the rod 10 of valve 8 connect the hole 7 to the atmosphere, after which the cavity of the main massager 1 is evacuated and the device is easily removed.

With general mechanical massage of the udder, a removable nozzle 2 is installed on the main massager 1, in the form of a corrugated bell, and for the handle 5 it is led to the udder. Opening the valve 8, set the magnitude of the efforts of the alternating vacuum on the udder of the animal. In the process of pulsation of the vacuum pressure set by the pulsator, the corrugated bell is compressed and expanded. In this case, the corrugated bell is compressed and the udder sections are partially deformed inside the bell, while massagers 16 made of elastic rods in the form of fungi that are installed on the cross-shaped platform 15 touch the udder, and the disks 23, moving by inertia along the rods, act on the udder, thereby providing additional massage. The magnitude of the impact of elastic rods and discs increases due to the inertia of the massager during compression of the corrugated bell. Upon receipt of atmospheric pressure air, the corrugated bell is unclenched due to the massager's gravity.

When compressing and stretching the corrugated bell, an additional massage of the entire udder takes place, due to the damping of the inertia forces of the moving masses. Thus, in the proposed device, the massage effect is formed due to the complex effect of inertial motion forces by the massagers and the action of flexible elements in the form of fungi with discs. All this together forms the technical novelty of the proposed device.

The removal of the device is carried out with the valve 8 closed. The shell 6 and the gasket 17 ensure the tightness of the connection.

Valve 3 blocks the flow of atmospheric pressure into the pipe 18, with a sharp increase in air flow occurring during an emergency fall of the massage bell from the udder. The filter 21 prevents clogging of the channels of the pulsator 20 and the pipe 18 and the hose 22 with foreign objects (animal hair, feed particles, etc.).
