RU2181241C2 - Teat cup - Google Patents

Abstract

FIELD: agriculture. SUBSTANCE: teat cup has casing, teat liner composed of inner and outer pipes united at their upper ends by means of seal and pivotal petal of deforming member, which are located in space between teat liner pipes. This space is communicated with teat cup cavity positioned under teat. Teat compression restrictors are positioned between pivotally attached petals. Vacuum is permanently maintained in teat cup cavity under teat. When vacuum is created in space between walls, teat liner is relieved and teat reservoir is filled with milk. When atmospheric air or excessive pressure is supplied to mentioned space, teat liner is compressed. Pressure is transferred through petals of deforming member to teat and the latter is gradually compressed from its lower part to upper part to force out milk from teat. EFFECT: simplified construction, increased efficiency and enhanced reliability in operation. 2 cl, 3 dwg

Description

 The invention relates to the mechanization of agriculture, in particular to milking machines.

 Known milking cup containing the housing, the nipple rubber and installed between them the nipple deformer in the form of petals in contact with the nipple rubber, and the mechanism for driving the petals [1].

 However, the known milking cup does not provide effective compression of the nipple in the process of squeezing milk from it.

 The objective of the invention is to increase the efficiency of squeezing milk from the nipple during compression of the nipple rubber.

 This object is achieved in that the milking cup contains a housing, teat rubber, a teat deformer in the form of petals in contact with the rubber. Nipple rubber is made in the form of two tubes located one in another and united in the upper part by a sealant. The deformer petals are pivotally mounted in the space between them and secured, and this space communicates with the suction cup of the glass. Between the petals of the deformer are installed compression limiters of the nipple, for example, in the form of rigidly mounted vertical plates.

 In an embodiment, between the petals there are compression limiters of the nipple by them.

 In FIG. 1 shows a teatcup, a general sectional view of a stroke of sucking milk into a nipple tank; in FIG. 2 - the same with the cycle of squeezing milk from the tank of the nipple; in FIG. 3 is a section AA of FIG. 2.

 The milking cup contains a housing 1, nipple rubber with inner 2 and outer 3 tubes united in the upper part by a seal 4, and a nipple deformer installed between these tubes in the form of petals 5 pivotally mounted in the lower part, for example, in a clip 6. Petals are made in the form flat springs with gradually increasing upward stiffness. The inner tube 2 of the nipple rubber in the lower part has openings 7 for connecting the space between the tubes of the nipple rubber with the suction cup 8, a milking cup communicating via a nozzle 9 through a collector of the milking machine (not shown) with a constant vacuum source. The space between the housing 1 and the outer tube 3 of the nipple rubber represents the inter-wall chamber 10 of the teat cup, which is connected by means of the pipe 11 to a variable vacuum source - a pulsator (not shown in the drawing).

 Between the tubes 2 and 3 of the nipple rubber on the holder 6 are rigidly installed limiters 12 compression of the nipple.

 A milking cup works as follows.

 When a milking cup is put on the nipple in the suction cup 8, and therefore in the space between the tubes 2 and 3, vacuum is constantly acting. When applying to the interstitial chamber 10 through the nozzle 11 from the pulsator of the milking machine, the outer tube 3 straightens, the petals 5 relax the nipple of the udder and its tank is filled with milk. There is a stroke of suction of milk (figure 1).

 Then, through the pipe 11 from the pulsator, atmospheric or overpressure air is supplied to the interstitial chamber 10. Due to the pressure difference in the chamber 10 and in the space between the tubes 2 and 3 of the nipple rubber, the walls of the outer tube 3 are compressed. Their pressure is transmitted by the petals 5, which deform compress through the walls of the inner tube 2 of the nipple, pinching it first at the base, and then gradually to its top. This provides a gradual extrusion of milk from the tank of the nipple, there is a cycle of extrusion of milk (figure 2).

 Next, vacuum is again applied to the inter-wall chamber 10, the nipple rubber (both its tubes) straightens, releasing the nipple, and it is again filled with milk.

 Next, the processes are repeated at a frequency specified by the pulsator of the milking machine.

 In the embodiment of the teatcup (Fig. 3), the stops 12 prevent excessive compression of the nipple and provide directional compression of the walls of the tube 3 of the nipple rubber in those places where the petals 5 are installed.
