Description

TECHNICAL FIELD The present invention relates to an improvement of a milk claw for collecting milk expressed from a teat cup unit in a vacuum type milking apparatus.

Generally, the liner nipple of the milk claw needs to be firmly connected to the teat cup liner of the teat cup unit.

2. Description of the Related Art For this reason, as shown in FIG. 5, the upper lid 1 is perforated in the milk claw main body A which is composed of a hemispherical upper lid 1 and a lower portion 2 having a milk discharge port, which are detachably coupled by screwing or the like. It is known that the liner nipple 3 is joined to the milk inlet by means such as welding and the valve 5 for opening and closing the milk outlet 4 of the lower portion 2 is attached to the liner nipple and the milk claw body. Has been.

Then, the teat cup liner 6 of the teat cup unit B is inserted into the liner nipple of the milk claw, and the teat cup unit B is attached to the udder of the cow for milking.

Incidentally, 7 is a teat cup shell, and 8 is a pulsating tube.

Problems to be Solved by the Invention In such a conventional milk claw, since the teat cup liner is made of rubber, it needs to be replaced every predetermined period.

However, when the liner nipple was inserted into the teat cup liner for a long time, the two were in a state of being firmly joined to each other, so that it took a long time to remove them and required a considerable force. In addition, there were things that did not reach the hands of children, old people, women, etc.

Further, when welding the liner nipple, it was necessary to remove burrs and oxides on the welded surface, which required a long time for assembly. Furthermore, when the milk claw is integrated, stainless steel is used from the viewpoint of strength and the like, but it has the drawback of being too costly.

In view of the drawbacks of the prior art, it is an object of the present invention to provide a tea cup liner that is easy to replace and a milk claw that is easy to assemble.

Means for Solving the Problems That is, the present invention comprises a plurality of liner nipples in the upper part and a milk outlet in the lower part, and a claw body having a milk storage chamber inside, and the plurality of liner nipples are detachable. In the case of being tightly joined to the milk claw body, the liner nipple and the milk claw body are joined by screwing a nip threaded on the outer periphery of the nipple fixing part of the female screw threaded on the milk claw body through a sealing material. The object is achieved by a milk claw in which a liner nipple is sandwiched by screwing together a fixing nut which is fitted or is externally threaded through a sealing material. It should be noted that the connection surface of the liner nipple with the liner may be roughened.

Action In the milk claw according to the present invention, the liner nipple is attached to the milk claw body, and the teat cup liner of the teat cup unit is attached to the liner nipple to perform milking. When the teat cup liner is replaced after milking several times, the liner nipple is removed from the milk main body, and a new liner nipple is screwed onto the milk claw main body to attach it.

Embodiment Hereinafter, the present invention will be described in detail according to an embodiment shown in the drawings.

In FIG. 1, 10 is the upper lid of the milk claw body A,
A nipple fixing portion 12 whose inside is threaded with a female screw is joined to the outside of the milk inlet 11 of the upper lid 10. A liner nipple 13 made of plastic or the like and having one end on the outer periphery screwed into a male screw is screwed through a seal ring (O ring) 14 to the threaded nipple fixing portion 12. The tip of the liner nipple 13 is bent inward. The liner nipple 13 and the teat cup liner 15 are connected by inserting the teat cup liner 15 into the liner nipple 13 as shown in FIG.

FIG. 4 shows another embodiment of the liner nipple 13 that is screwed into the nipple fixing portion 12 of the upper lid 10 which is threaded with a female screw, and a fixing nut 17 is connected to the joint portion of the liner nipple 13. The clamp nut 17 has a large diameter so that it can be easily removed and attached. Further, FIG. 3 shows a teat cup liner in which the liner nipple 13 is joined to the teat cup liner 15 in advance so as to be difficult to remove. In the case of the liner nipple 13, the teat cup liner 15 is attached and removed together with the teat cup liner. Liner nipple
As shown in FIG. 2, the rough surface 16 of the joint 13 with the teat cup liner 15 increases friction and makes it difficult for the teat cup liner 15 to come off.

In the case of the embodiment according to the present invention, it is preferable that the outer diameter of the liner nipple is smaller than the inner diameter of the liner mounting opening of the teat cup shell in consideration of removing the teat cup liner from the teat cup shell.

Effect As described above, the milk claw according to the present invention can be manufactured separately because the milk claw body and the liner nipple can be detached, and the manufacturing cost is low and the assembling work is easy. .

Further, the teat cup liner can be exchanged for each liner nipple, and the teat cup liner can be simply removed from the milk claw body without pulling the teat cup liner out of the liner nipple, which simplifies the removal work.
