Description

The invention relates to agriculture, in particular to milking cows on livestock farms and complexes.

Known control devices for milking cows, comprising a sensor nacha- ⁵ la and closure milking disposed in the milk hose of the milking machine, an electronic unit mounted on the individual milking machine and associated start and end sensor SP milking and [2].

The disadvantages of the known devices are the low accuracy of control of the beginning and end of milking and the relatively high negative effect of the milking machine on the nipples of the udder of cows.

The purpose of the invention increase accuracy _m Nosta control the start and end of milking and mitigate the negative impacts of the milking machine to the teats of the udder of cows.

The goal is achieved by the fact that the electronic unit is equipped with a time relay, a pulse generator, an intermediate relay, with a coil and normally open contacts, a power supply, counters for the number of milked cows, the number of milked cows with increased milking time, the total time of overexposure of the milking cups and indicators of start and milking end, and the coil of the intermediate relay is connected to the milking start and end sensor and the power supply, and its normally open contacts to the milking start indicator, the relay output to Yemeni and the counter number of cows milked, milking closure indicator coupled to the output time switch, and counts quantity of milked cows with increased total milking time and overexposure teat cups are connected with the output timer, the pulse generator and power supply.

location is shown

On figs on an individual milking machine; in FIG. 2 diagram of the device.

The device contains a sensor 1 for the beginning and end of milking, located in the milk hose 2 of the milking machine 3, a feeder 4 mounted on an individual milking machine 5, with input 6 and output 7 doors, a feed meter 8 and handles 9 of the input and 10 and output doors, electronic block 11, which has indicators 12 of the beginning and 13th end of milking, counters 14 of the number of milked cows, 15 of the number of milked cows with increased milking time, 16 of the total overexposure of milking cups 17 ”time relay 18, made on transistors 19 and 20, gene pulse generator 21, an intermediate relay 22 with a coil 23 and normally open contacts 24, a 25 ”power supply unit with a transformer 26, a rectifier bridge 27 and a switch · 28, in which the coil 23 of the intermediate relay 22 is connected to the milking start and end sensor 1 and the unit power 25, and its normally open contacts - with the indicator 12 of the start of milking, the output of the time relay 18, as well as the counter 14 of the number of milked cows. The indicator 13 of the end of milking is associated with the output of the time relay 18, and the counters 15 of the number of milked cows with increased milking time and 16 total time overexposure of the milking cups 17 are connected with the output of the time relay, the pulse generator 21 and the power supply 25.

The device operates as follows.

The milking master, using the handle 9, opens the front door 6 and lets in the first cow, after which it feeds the feeder 4 with the help of the dispenser 8 and switches on the electronic unit 11 with the switch 28, which remains on until the end of the milking of the whole herd and puts on the milking cups 17 · Upon receipt milk into the milk hose 2 and the milking start and end sensor 1, the latter generates a signal that, via normally open contacts 24, turns on • the milking start indicator 12, a time relay 18 configured for a five-minute shutter speed, and a count of 14 ARISING milked cows.

"About ts

After stopping the flow of milk, the milking start indicator 12 turns off and the milking end indicator 13 turns on, the unit is fixed with a counter 14 of the number of milking cows, in the case of a milking cup overexposure 17, the first overexposure is recorded with a 15 milking cows counter 15, and a total counter of 16 milking cups with a counter 16 overexposure time.

For operation of the counter 16 of the total time overexposure of the milking cups 17 use second pulses generated by the pulse generator 21.

After milking is completed, the master removes the teat cups of the handle 10, opens 7 and releases the cow, closing the exit door of the individual machine cow.

The operation of the device during milking subsequent cows is similar to the work described above.

Thus, the device provides increased accuracy of control of the beginning and end of milking and reduces the negative impact of the milking machine on the nipples of the udder of cows.

and with the help of the exit door after which, 7, lets in milking the following-
