Embodiment Construction

[0025] For ease of further explanation, the direction and orientation of the liner herein refers to the position of the liner when it has been pushed onto the teat. The parts shown at the top in the figures are the parts facing the bottom of the udder, therefore, the parts of the milking device that lead the milk to the collection container are connected to the parts shown at the bottom.

[0026]First refer to figure 1 , which describes a first preferred embodiment of the invention. In the example described, the bushing 10 comprises a barrel portion 14, a retaining edge 20 for pushing onto the housing 40, connecting the shaft or the upper edge 24 of the barrel portion 14 near the upper edge 42 of the housing 40 to the The transition portion 22 of the retaining edge 20 is connected to said transition portion 22 and the head portion 12 of the retaining edge 20 also near the upper edge 42 of the housing 40 . These elements are parts inside the teatcup, which are closely interco...

Abstract

The invention relates to a teat rubber for a substantially undeformable milking cup sleeve (40) for forming a two-chambered milking cup, by means of which milk is extracted from a teat in a suction milking process through a milking vacuum during a suctioning stroke and the teat is massaged during a relief stroke, wherein the teat rubber comprises a head part (12) that is substantially rotationally symmetrical relative to its longitudinal axis and a shaft part (14) that is connected to the head part (12) by means of a transitional part (22), wherein the shaft part (14) is flexible, it surrounds the teat and reacts to the alternating changes in pressure during the suctioning and relief strokes by changing its form. The head part (12) is embodied as an annular tube (16), which forms an insertion hole (18) for the teat (Z), and which ensures sealing relative to the milking vacuum and the best possible grip of the teat rubber to the teat without excessively contracting the teat both during the suctioning and the relief strokes. The annular tube (16) is configured in such a way that an annular hollow space (3) is defined by the teat, the transitional part (22) and the annular tube (16) once the teat in introduced into the shaft part (14). The diameter inside the annular tube (16) is smaller during the suctioning stroke than the diameter inside the area of the shaft part (14) provided for the teat. The annular tube (16) is so flexible that its inner diameter can be enlarged radially outward during introduction of the teat and its axial length can be changed.

Description

technical field [0001] The invention relates to a liner for forming a substantially non-deformable teatcup shell of a two-chamber teatcup, by means of which liner is sucked during the milking phase by the milking vacuum provided. Pump milk from the nipple during breastfeeding and massage the nipple during the resting phase. Background technique [0002] In a milking machine, the bushing (or teatcup bushing or teat rubber) forms the contact area between the milking machine and the animal being milked and thus forms part of the milking machine which is necessary, but not easy to design. It is especially difficult to design the head part of a bushing (nipple bushing) with a head opening, which has to fulfill several functions: said head opening or, in other words, the insertion opening for the nipple has to make itself Adapts well to different teat shapes and sizes, as well as teat positions and conditions, in order to seal the milking vacuum under the teat from ambient press...
