Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to teat cup inflation.

A common problem with milking equipment is that one or more parts of the cluster are not milked satisfactorily. The reason for this is usually thought to be that one or both ends of the inflation are twisted in cross-section relative to the other end, and the inflation is subjected to an undesirable force from the pedestal, making it difficult to milk the milk. The expansion and contraction of nipple cup inflation, which is a desirable condition for efficient performance, is no longer performed.

This type of problem is difficult to recognize, especially if the operator does not have a good understanding of the mechanics of the milking machine, and therefore may overlook twisting in each teat cup assembly. There is.

It is an object of the invention to provide a new and improved teat cup inflation which, when placed in combination with a teat cup shell, does not experience any twisting of the inflation relative to the teat cup shell. , or almost none.

In many conventional milking machines, teat cup shells (usually made of stainless steel) are used to enclose the individual inflations. In most milking facilities, each cluster is equipped with a vacuum source. Therefore, it is desirable to prevent the introduction of air into the vacuum system when inserting or removing the teat cups, and for this purpose the milk lines leading to the teat cups that are not in use must be separated from each other. It is desirable that the milk-receiving nibble of the cluster claw to which the milk line is connected is slanted outwards and upwards to completely separate the teat cups that are not in use. Sometimes they fall downward so that the line leading to the milk receiving nibble is sealed against the end of the nibble. However, the milk line is not very flexible and the conventional teat cup assembly A complete seal is not always obtained because the distance between the point where the milk line engages the cluster claw nibble and the center of their collection is often too close.

SUMMARY OF THE INVENTION Accordingly, another object of the present invention is to provide a teat cup shell with a weight that can solve the above-mentioned problems when combined with the above-mentioned inflation.

Other purposes of the non-invention and effects achieved by the non-invention will become clear from the following description based on examples.

According to a first essential aspect of the invention, the teat cup inflation has a generally cylindrical elongated indentation whose upper part forms a teat chamber and whose lower part forms a milk chamber;
The upper portion of the body is provided with seven downwardly depending langes so as to form an upper engagement portion with the teat cup shell between the upper portion of the inflation and the flange.

In this case, at least the above-mentioned upper retaining portion with the teat cup shell is provided with positioning means, which engages with the positioning means on the upper part of the teat cup shell.
plimentary engagement), so that when the teat cup shell is combined with the inflation, no or very slight twisting in the cross section of the inflation relative to the teat cup shell occurs.

According to a second aspect of the invention, in the assembly of the teat cup inflation and the teat cup shell as described above, the main body of the teat cup shell has an open end at its upper part, and the teat cup of the teat cup inflation and the teat cup shell have an open end. The lower part thereof has an opening through which the lower part of the main body of the nipple cup inflation passes.

Hereinafter, each essential aspect of the invention will be explained based on the accompanying drawings showing embodiments.

In FIGS. 1 to 7 showing the first embodiment of the present invention, the main body of the teat cup inflation, generally indicated by the arrow l, has an elongated, generally cylindrical shape, and the upper part of the teat cup inflation body has a teat chamber 2, a The lower part is the milk chamber 3. Main body 1
The upper part 1a of the inflation is provided with a downwardly depending flange 4, and between the upper part 1a of the inflation and the flange 4 there is formed an upwardly engaging portion with the teat cup shell generally indicated by an arrow 5. . In this case, positioning means as indicated generally by arrow 6 are provided at least in the upper engagement with the teat cup shell mentioned above and arrow 8
When the teat cup shell 8 and the inflation 1 are assembled, the teat cup shell 8 In contrast, the inflation 1 is not likely to be twisted in its cross section, or is very slight.

In the embodiments shown in Figures 1 to 4 of the accompanying drawings,
The inflation 1 is provided with positioning means 6 at which the inflation 1 engages the upper part 8a of the teat cup shell, and positioning means 6 are provided at which the inflation 1 engages the upper part 8b of the teat cup shell. engaged.

In the embodiment shown in FIGS. 5 to 7, the inflation is provided with positioning means only at its upper part, and in that part the inflation 1 engages with the upper part 8a of the main nipple stub 8. .

In the positioning means 6 for the upper portion of the nipple cup inflation, three notches 9 may be provided at equal intervals on the circumference within the groove 10 inside the upper engaging portion 5 for engaging the nipple cup. That is, the notches 9 are provided at intervals of 120°.

The groove 10 is arranged to receive the flange 11 of the nipple cup shell 8, and has a fitting cutout 12 therein.
is provided. When the inflation 1 and the nipple cup shell 8 are assembled as shown, the inflation 175 cannot be twisted in its cross section relative to the nipple cup shell 8.

As mentioned above with respect to the embodiments illustrated in figures 1 to 4 of the accompanying drawings, the inflation 1 is also provided with positioning means 6 in the lower part 8b of the teat cup shell [in such a position that the inflation engages]. This positioning means 5 consists of three bulges 13 provided on the permanent outer surface of the inflation, and is arranged to engage with the positioning means 7 of the nipple cup shell 8.

The bulges 3 are equally spaced at 1200 mm intervals and have flanges 16 extending inwardly against the opening 17 of the teat cup shell 8 associated with the inflation.
It is adapted to just engage a notch provided in the inner surface 15 of.

In this way, in the assembly of the teat cup shell 8 and the inflation 1, the inflation 1 is twisted within the cross section relative to the teat cup shell 8 even in the portion where the lower part of the inflation passes through the teat cup shell. Nothing can happen.

In order to facilitate the assembly of the inflation 1 and the teat cup shell 8 together, the inflation and the teat cup shell may be provided with indexing means (an example of which is shown in Fig. 5).
6 and 6.

The heading means indicated generally by arrow 18 may be located at the top and bottom of the assembly. Heading means 18 at the top of the assembly are inflation 1
and a protrusion 19 on each outer surface of the teat cup shell 8, which serves as a mark to ensure that the inflation 1 is correctly attached to the teat cup shell 8. At the bottom of the assembly is the flange 1 of the nipple cup shell.
Notches 10 are provided at intervals on the lower outer surface 21 of 1.
The outer surface of the inflation 1 is also provided with a notch 22 which also provides a mark for correct attachment of the inflation 1 to the teat cup shell 8.

Figures 8-13 of the accompanying drawings illustrate the nipple force tubes combined with inflation in accordance with the present invention. Inflation l and nipple cup shell 80
The assembly may be connected to a cluster claw (not shown) with a nibble (in which the lower end of the inflation 1 is engaged so that the interior of the cluster claw communicates with the milk chamber 3 of the inflation 1). Can be done.

Before and after removing the teat cup assembly after milking the cow, they are allowed to hang vertically from the cluster claw. In such a state, the inside of the inflation or at least its lower part will be sealed due to the sloped tip of the nibble of the cluster claw. In order to obtain a proper seal, in this condition the teat cup assembly must be such that the beveled end of the milk nibble of the milking claw is blocked by the inflation.

The teat cup shells illustrated in Figures 8-13 have weights embedded therein to bias the mass of the assembly toward the free end of the assembly.

The nipple cup shell 8 is made of a moldable material such as plastic, and has a weight made of a heterogeneous material, generally indicated by the Q1 arrow 23, integrally molded and embedded within its wall. The illustrated nipple cup shell has an open end 2
4 and a lower end 25 with an opening 27 through which the J1 vibration line nibble 26 is attached and the lower part of the nipple cup inflation can pass through.

Preferably, the bore 28 of the teat cup shell 8 has a width substantially greater in one plane than in another plane orthogonal thereto. In the illustrated example, such preferred conditions are met by having the bore oval in cross-section and tapering from top to bottom; however, the bore of the teat cup shell may have other shapes. Of course. In the illustrated example, the outer surface 29 of the teat cup is of circular cross section 9 and has seven lunges 11 to facilitate engagement with the teat cup inflation.
is provided.

As mentioned above, the upper part of the nipple cup has a weight embedded therein, indicated generally by arrow 23. The embedded weight 23 may be a lead weight, but its shape is in the form of a continuous ring, and in the illustrated embodiment it is completely embedded in the moldable material. It is curved and has a cross-sectional shape that corresponds to the cross-section of the upper part of the nipple cup.

If the bore of the nipple cup shell has an egg-shaped cross-section, the outer circumference of the lower end of the nipple 25 may also be egg-shaped (see Figure 11), just below the weighted end of the nipple 8. A connecting portion 30 is provided between the circular outer periphery and the egg-shaped outer periphery. It is most convenient for the outer shape of the teat cup to be in the shape shown in the diagram, but it depends on the shape of the part where the oval-shaped lower end of the nipple cup is surrounded by the thumb and other fingers when grasped by the operator. This is because it is compatible.

The size of the weight 23 may be set to a size that is suitable for each milking facility and sufficiently achieves the purpose, but it may be made of pellets made of a suitable metal such as steel with a high specific gravity (not shown), for example. The weight may be shaped like a large number of vertically arranged lines. It is also possible to use liquid as the weight. For maximum effectiveness, the length of the weight 923 should span the entire length of the upper portion 29a of the nipple cup shell.

Referring to FIGS. 12 and 13 of the accompanying drawings, they illustrate an embedded weight 23 whose cross-section is similar to that of the intangible upper portion 29a of the nipple cup shell 8.
The upper surface 2.3b has several shallow holes 23a.

A die (not shown) is used to mold the nipple cup, and at that time, a finger-like holder (not shown) connected to the die is engaged with the embedded weight in the hole 23a. Weight #) By supporting it concentrically within the entire die, weight i is held in the correct position until the molding material is injected into the die and envelops weight i. Thereafter, the finger-shaped holder is removed from the hole 23a and the remaining space is filled with an appropriate material to complete the manufacturing process.

Alternatively, a plastic cradle (not shown) may be provided to support the weight 23 within the die during molding.
Thereby, the weight may be positioned away from the stone mold of the teat cup shell forming die. The cradle may be made of a material that is compatible with the cradle, but for example, a pair of ring-shaped members may be separated using a support and the weight may fit onto the cradle during the molding process. It may be possible to do so.

In the above explanation, nipple cup inflation 1
is combined with the teat cup shell shown in FIGS. 8 to 13, but the uninvented inflation can also be used with other teat cup shells such as conventional metal shells as long as they are modified appropriately. Needless to say, they can be combined.

The embodiments of the present invention described above are merely illustrative, and it is natural that they may be modified or other features may be added without departing from the gist of the invention as set forth in the claims. .
