摘要:
A teatcup liner comprises an upper mouthpiece, an intermediate barrel and a lower connecting tube. The upper mouthpiece further comprises a mouthpiece transition, a mouthpiece lip, and a groove formed in an outer surface of the upper mouthpiece. The intermediate barrel extends along an axial direction for receiving a teat inserted axially thereinto through said mouthpiece. An inner dimension of the upper mouthpiece defines a cavity bore and the groove is located substantially in line with the largest diameter of the cavity bore.

A teatcup liner for a teatcup has a longitudinal shape extending along a longitudinal axis (x). The teatcup liner includes a barrel (2) having a length (L) and defining an inner space (21) for receiving the teat. The barrel has a polygonal cross-sectional shape transversely to the longitudinal axis along the barrel. The polygonal cross-sectional shape defines a plurality of corner portions and a plurality of side portions, each connecting two of the corner portions. Each corner portion includes an inner surface facing the inner space and having an inner radius extending from the inner space to the inner surface. The inner radius is equal for each corner portion. Furthermore, the inner radius of each of the corner portions is at least 4 mm at a centre part of the corner portion.

A vent plug for a milking liner has a shielded inlet that reduces the likelihood that it will become clogged with debris from the floor of the milking parlor. In one embodiment, the vent plug has a plurality of redundant inlets that allow the vent plug to function if one of the inlets becomes clogged. In another embodiment, the inner flange of the body of the vent plug is at least twice the thickness of the body tube to help secure the vent plug in the milking liner.

A device for milking a dairy animal, comprising a teat cup with a teat liner and a disinfection device for disinfecting at any rate at least a part of the teat liner by means of a disinfecting fluid. The disinfection device comprises a heating device for heating the disinfecting fluid, and the disinfection device is suitable for bringing the disinfecting fluid into contact with at any rate at least a part of the teat liner. A control unit is suitable for controlling the disinfection device. The heating device is suitable for heating the disinfecting fluid to such a temperature that the disinfecting fluid has a temperature of at least approximately 95° C. when it is in contact with the teat liner. The control unit is suitable for registering values of at least one control parameter of the disinfection device.
摘要:
A device (1), for example a teat liner, for reception of a teat comprising an element (2), which presents a thin, flexible wall surrounding a channel for reception for said teat, wherein said wall in a direction towards the channel has an inner side and in direction from the channel an outer side. The outer side of the wall is provided with a large number of surface enlargements (3), which have such a form, size and distribution that they form obstructions to propagation of cracks on the outer side of the wall. The invention also relates to a method for the manufacture of the device.
摘要:
A method for milking animals, such as cows, wherein the cows enter a milking compartment where teat cups of a milking apparatus are automatically attached to their teats. In the milk conduit system leading from the teat cups, sensors are placed to measure a variety of parameters and provide data to a computer for processing and presenting the data which the computer receives from the sensors. This data includes information from a flow sensitive sensor, a temperature sensitive sensor, and a sensor sensitive to electric conductivity of the milk. Information is also provided from the milking compartment to the computer on how much food is consumed by each animal, and how many times each animal enters the milking compartment. The computer compares the data received from the various sensors with similar data from immediately preceding selected periods of time, whereby a progressive average of the relevant data is available and compared for each animal. The data received for ill or animals in estrus differ from those of healthy and non-estrus animals, whereby the sensors are detecting and the computer is processing and determining from the data provided from the sensors on a continuing basis which animals are and are not healthy or in estrus.

A milking plant for cows is provided with a milking machine comprising teat cups, which are connected separately to the teats of an animal. The milk obtained from each udder quarter is conveyed through a separate line to a milk measuring device. The milk measuring device includes four milk meters, one for each teat cup, having separate discharge lines coupled to common discharge lines which connect with a circulation line or loop that includes a bulk milk cooling tank, a two-speed or variable speed pump, and a plurality of heat exchangers for precooling the milk received from the common discharge lines before it is received in the bulk milk cooling tank and to recirculate and cool the milk received in the bulk milk cooling tank. After the milk has been discharged from the bulk milk cooling tank and the system is to be disinfected, washed and rinsed, the heat exchangers being used in a heat pump arrangement, can heat the fluid therein as selected and desired for sanitizing the system.
摘要:
A milking system combines the use of a thin-walled non-distensible floppy liner (82) with the application of positive pressure during the off portion of the milking cycle, and overcomes prior problems of congestion, oedema, hyperkeratosis, and slow milking. In a further aspect, the thin-walled floppy liner is operated as a pressure switch limiting the amount of negative pressure applied to the lower tip of the teat (16). In a further aspect, cross-contamination from another teat through the milking claw (36) is reduced by minimizing volume change within the liner (82) below the teat (16) during milking.

A teat cup for hydraulic milking apparatus comprises a shell and a liner. The liner has a body part within the shell, a mouthpiece at one end of the body part which mouthpiece defines an opening for receiving a teat during milking, a short milk tube at the other end of the body part, for connection to a clawpiece, and an air passage extending through the body part from the inside to the outside thereof. The shell has a first inlet to which a vacuum pulse tube can be connected and in use pressurize the space between the shell and the liner body part, a second inlet to which an air admission tube can be connected and a passageway defined within the shell itself or within a part rigid therewith and communicating the second inlet to the air passage in the liner body part, whereby air may be admitted to the interior of the liner body part at will.
摘要:
A milking system for dairy animals comprising individual teat cups attachable to the respective teats of the animal's udder, a measuring device to determine the volume of milk discharged from individual teats, a central vacuum system to aid the discharge of the milk from the teats as well as to propel both the milk and the cleaning fluid through the system's fluid lines, a cooling tank, and an array of sensors to determine various parameters of the milk and milking system, including temperature sensors, milk conductivity sensors, air-to-milk ratio sensors, pressure sensors and fluid level sensors. The sensors are arranged at various points in the milking system, including in the individual teat cups, the milk measuring device and the discharge lines, and are optionally coupled to a central computer which controls both the individual components of the milking system and working parameters of the system as a whole, including an automatic cleaning system for cleaning the teat cups, fluid lines and cooling tank. The system diverts milk from the milk otherwise collected that has too high of a temperature or more than a predetermined conductivity indicating it may not have been produced in a healthy teat or udder.
