Method for testing of teat cup liner for milking unit

FIELD: agriculture, in particular, milk unit testing processes.

SUBSTANCE: method involves stretching teat cup liner in conjunction with milk pipe for testing teat cup liner; applying working force to milk pipe site where it is connected to teat cup of milking unit. The given force provides for normal tension of teat cut liner in teat cup.

EFFECT: increased precision of tests.

 

The invention relates to agriculture, in particular, to milking machines.

Closest to the claimed technical essence is a way of testing sokovich tubes made separately from milk, including the measurement of length tube liners from the end surface of the suction Cup to its edges, trimming liners tube if necessary to the desired length, the definition of its elongation under the action of the cargo to be secured to the tube and providing its normal tension in the teat Cup (Apion, Iselius, IAASB and other maintenance of livestock farms and complexes. - M.: Kolos, 1973, s-162).

The disadvantage of this method is a significant difference in the tension of liners tube tested according to the method, and its actual tension in the teat Cup, which is the acquisition of milking machines tested tubes does not provide the necessary accuracy of the tension in the set of one of the milking apparatus and reduces the efficiency of machine milking of cows. Tension liners tube depends on its extension. However, depending on the distance from the end of tube liners installed mounting ring will be different elongation, and hence the tension in her teat Cup.

Moreover, when the test load is fixed nasekomoe tube and the elongation exactly liners tube.

In fact when installing liners tubing Assembly with milk in the teat Cup is extended not only the nipple, but milk tube, and that when tested by a known method is ignored and the installation kit in the teat Cup makes a significant difference in elongation, and hence the tension tube liners in the teat Cup.

All this leads to a significant difference in tension sokovich tubes in the teat cups when they are picking and reduces the efficiency of machine milking of cows.

The invention solves the problem of increasing the accuracy of the test, the efficiency of machine milking, improve the quality and reliability of the test method sokovich tubes, as well as ease of maintenance.

This is achieved by the known method of test liners tube, milking equipment, including its extension with a work force, to ensure the normal tension in the teat Cup and the definition of elongation, with the nipple stretch tube Assembly with milk tube, the tensile stress is applied to the milk pipe in connection with its teat Cup device.

According to the present method, during the test, the conditions of distribution of loads is identical performance in the milking process. It provides quality testing due to the fact the particular installation tension tube liners in the teat Cup, and as a result, the efficiency of the milking.

Fixation of the cargo at the milk pipe in the place of its connection with the sleeve of glass improves the efficiency of milking by determining the actual tension, ease of maintenance and reliability tests.

The method is as follows. Nipple and milk tubes are washed in detergent-dezinfitsiruyuschim solution and rinse with clean water.

After drying, measure the length of each tube liners and, if necessary, cut the tube to length 155 mm, then the outer part of the tube liners install the mounting ring at a distance of 5 mm from its end and assemble the kit (liner tube milk tube and mounting ring). Then nipple tube complete with breast tube set pricescom on the mandrel of the device and the load, weight 6 kg, is fixed on the milk pipe in the place of its connection with the sleeve of glass. Then pull the liner tube, the said cargo and set extension. Obtained for each set value are recorded in the log book at the same time, test liners tube is not more than 5 C.

After the test nipple tube in accordance with the rules of the milking machine are completed in groups of rigidity.

Method of test liners tube milking devices is a, including its extension with a work force, to ensure the normal tension in the teat Cup and the definition of elongation, wherein the liner tube stretch Assembly with the breast, while the operating force applied to the milk pipe in the place of its connection with the teat Cup device.

FIELD: research of muscular activity, in particular, equipment for registering of muscular tissue resiliency.

SUBSTANCE: apparatus has casing positioned onto surface to be measured, vacuum pipeline, measurement sensors located within casing, and registering unit. Casing is formed as bowl-shaped housing connected through collector to vacuum pipeline. Two working tools are arranged in diametrically opposite relation within housing and connected through distributor and collector to vacuum pipeline. Distributor is made single-chambered and is equipped with atmospheric air admission apertures, which are closed by spring-loaded valve. Collector is made in the form of two paired vacuum regulators, each being formed as needle-type valve mounted in casing for regulating spring compression or extension by means of screw pair for restricting access of vacuum gage pressure or atmospheric pressure. Working tools are formed as bellows with base and cover, to which vacuum funnel is attached by means of equal resistance beam with tensometers. Bellows and vacuum funnel cavities are communicating with one another through elastic branch pipe. Each of working tools is furnished with tensometers for measuring displacement of cover with vacuum funnel relative to base. Signals generated by sensors are delivered through tensoamplifier to automatic recorder.
