MECHANICAL PNEUMATIC PULSATOR WITH SPEED ADJUSTABLE MESSAGE

Technical Field

The present invention relates to a pulsator, which is the basic element of milking machines used for milking sheep and cattle. The present invention particularly relates to a mechanical and pneumatic pulsator to perform milking when desired, and to massage by creating a bypass channel.

Prior Art

Today, in milking machines in the livestock sector, pulsators allows for milking of sheep and cattle. The milking process is carried out by applying vacuum to the udder of the animal to which the pulsators are attached, at certain periods.

In the state of the art, electronic pulsators are widely used in milking machines. Electronic pulsators work in connection with the central electronic control unit. These pulsators, which work with the control unit, cut off the impulse of the pulsator in cases such as a power cut or short circuit of the control unit. This is the most common problem that hinders the milking process. In addition, electronic pulsators are complex structures with a large number of components. This causes fatigue of the components, thereby shortening the life of the pulsator and increasing the cost.

In the milking process of sheep and cattle, the massage process is as important as the milking process. Massage process is performed before and after the milking process. The massage process performed before the milking process is performed in order to obtain more milk during milking. The massage process after the milking process is performed such that the udder can be relax for the next milking process easily. Massage before milking is necessary for the blood in the udder to circulate comfortably. Regular massage before and after milking increases the yield and quality of the milk that is obtained. In this context, the massage applied to the udder is a very important both for the udder health of the animal and for the yield and quality of the milk obtained. Some of the pulsators in the state of the art do not have a massage property. In such a case, the owner of the animal should massage by hand during milking. This is a situation that hinders the process since it requires extra manpower.

In the state of the art, a mechanical pulsator is mentioned in the patent application numbered TR.2020/01327. The relevant document is a study conducted to eliminate the periodic deviation between the pulse rates of the two arms attached to the nipple, in other words, to reduce the limping value. However, it does not give any information about the massage property in mechanical pulsators.

Consequently, existence of the inefficacy and disadvantages of the above- mentioned pulsators and the inadequacy of the existing solutions necessitated making an improvement in the related technical field.

Objects of the Invention

The mechanical pneumatic pulsator of the present invention has been developed to eliminate the disadvantages of the art. The main object of the present invention is to obtain a pulsator that works without the need for electricity, that has both milking and massage properties, and that has a long service life.

The pneumatic pulsator of the present invention can switch to massage while milking or to milking while massaging with a single spindle movement by means of the mechanical structure thereof. Providing the switching between milking and massage with a single spindle movement extends the service life of the pulsator.

Since the pneumatic pulsator is not driven by the electrical control unit, it is not affected by any problems in the electrical circuits. In this way, even if there is an electrical problem, there is no disruption in the milking process.

It is ensured that all of the milk is obtained from the udder by means of the massage property, which is one of the main purposes of the pneumatic pulsator of the present invention. Thus, both the animal health is protected, and the quality of milk is increased, and thus, the milk yield is increased. Detailed Description of the Invention

The mechanical pneumatic pulsator realized to achieve the object of the present invention was illustrated in the attached figures.

Figure - 1 is the general view of the mechanical pneumatic pulsator.

The pulsator (A) shown in Figure - 1 is not connected to any electrical control unit and has a mechanical property. Since the pulsator (A) also has a pneumatic property, a vacuum pump is connected to said pulsator (A) and the milking process is performed. As in the state of the art, the pulsator (A) of the present invention also has an air passageway (2) through which vacuum air is passed through the body (1). The milking speed of the pulsator (A) is adjusted with the adjustment screw passed through the adjustment hole (3) on the air passageway (2), as in the state of the art. Milking process is carried out by giving a certain period to the vacuum air applied with the adjustment screw (3) passed through the adjustment hole (3) formed on the air flow path (2) located in the body (1) of the pulsator (A). The frequency of the vacuum air passing through the body (1) must increase in order for the pulsator (A) of the present invention to switch to the massage process while milking. Two channels (2) were formed in the air passageway (2) in order to increase the frequency of vacuum air. The channels (4) are formed as one on each side of the adjustment hole (3) and perpendicular to the air passageway (2). Channels(4) have equivalent length values. A shaft (6) is placed at the end of the channels (4) to form a right angle with said channels (4). At one end of the shaft (6), there is a switch (8), which is positioned outside the body (1). A channel (7) is formed on the shaft (6) through which the vacuum air can pass. The length of the channel (7) formed on the shaft (6) has the same length as the distance between the two channels (4). Thus, when the channels (4,7) are combined, an "U" form is formed.

When the switch (8) is in the closed position, the flat surface of the shaft (6) closes the two channels (4). In other words, when the key(8) is in the closed position, the channels (4) are blinded by the help of the shaft (6). Thus, vacuum air does not pass through the channels (4), and vacuum air passes only through the air passageway (2). The pulsator (A) performs the milking process by passing the vacuum air only through the air passageway (2). (Figure - 2)

When the switch (8) is turned on, the shaft (6) performs a rotational movement and the channel (7) on said shaft (6) and the two channels (4) are combined. By combining the channels (4,7), a bypass channel is formed inside the body (1). When the switch (8) is in the open position, vacuum air passes through both the channels (4,7) and the air passageway (2). The frequency of the vacuum air increases with the bypass channel formed on the air passageway (2) by means of combining the channels (4,7) and the pulsator (A) starts the massage process. (Figure - 3)

The channels (4), the shaft (6), the channel (7) on the shaft (6) and the switch (8) can be inside the body (1) as well as in an adapter (9) having the same positions. When the adapter (9) is connected to the body (1), some of the channels (4) formed on both sides of the adjustment hole (3) are formed inside the body (1) and the other part is formed in the adapter (9). Sealing element (5) is used at the junction points of the channels (4) in the body (1) and the adapter (9). The sealing element (5) ensures that the vacuum air in the channel (4) does not leak air while passing from the body (1) to the adapter (9). A gasket and/or o-ring are used as sealing element.
