Description

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

The purpose of the invention is to increase the effectiveness of udder massage and improve hygiene and sanitary conditions.

; FIG. 1 depicts a milking manipulator; in fig. 2 - teat cup and massage unit, side view; in fig. 3 is the same, top view.

The milking manipulator consists of a carrier part comprising a trolley 1 with rollers 2, driven by a pneumatic cylinder 3 and lever C. On the trolley 1, a pneumatic cylinder 5 with a piston 6 and a stem / pneumatic cylinder 5 is vertically mounted inside a glass H which also includes an e-disk guide 10. The disk 10 is articulated with the rod 7. Between the pneumatic cylinder 5 and the cup 8 there is a spring 11 that holds the guide 9 together with the peep 10 in the upper position. Ring 12 and limiter 13 prevent the free exit of guide 9 from glass 8.

On one side of the disk 10 is attached a device for preparing the udder for milking 1C, a pulsator 15, a control valve 16 with an air hose 17. A hose 18 is supplied to the washing liquid device. On the opposite side from the device for preparing the udder, there is a milking machine that includes cups 19, milk 20 and air 21 tubes, a distributor 22 attached to the disk 10 and connected with a hose 23 to a pulsator 2k, which, in turn, is connected to the vacuum line 25. The suction pans of the milking cups 19 are connected in pairs (for Front quarters and rear quarters udder) using tees 26.

The control unit includes sensors 27, which are connected to the milking cups 19 by the hoses 28 and 29, and to the milk line 31 by hoses 20. Each of the sensors 27 is provided with a clip 32, which serves to bring it to the starting position.

The massage unit consists of an i-s pneumatic cylinder 33, four levers 3 and four thermoplates 35. Pneumatic

Lindra 33 is connected to pulsator 37 by hose 36. Thermoplates 35 are connected to water heater 0 by hoses 38 and 39 and water comes from water line 1. Crane 2 is installed on hose 38. For manual control of pneumatic cylinders 3 and 5, there are valves CZ and CZ. In the pneumatic cylinder 33, a piston 5 is installed with a rod 6 and a spring 47. The upper end of the rod 6 is connected to a crosspiece 8, to which the arms 3 are pivotally connected to the fork-shaped ends, each of which is equipped with a milking cup 19. The rod 6 of the pneumatic cylinder 33 has a restrictive nut 49 A thermoplate 35 is attached to the teat cup 19 by means of a clip 50. The clips 50 have square pins 51 in cross section 5

зы 52 levers Thermoplates 35 are connected in series by hoses 53.

The manipulator works as follows.

The operator opens the valve kk and the vacuum from the vacuum tube 25 enters the pneumatic cylinder 5, its piston 6 is retracted, compressing the spring 11 and pulling the rod 7 along with the disk 10. Then the operator moves the cart 1 mounted on the floor of the teat Cup on rollers 2, so so that the 1C device is under the udder of the animal, and the teat cups 19 are on the side of it. When closing the valve kb, the spring 11 pushes the cup 9 together with the disk 10 up, and the device 1J covers the outflow of the animal. Sanitary treatment of the udder (undermining, massage and handing over the first milk streams) is carried out by the 1C device to prepare the udder for milking.

After preparing the udder for milking, the operator opens the valve kk and the disk 10 is lowered. Then, turning the disk 10 to 180, the operator brings the milking cups 19 under the elbow cups and closes the A4 valve. The disk 10 is raised and the operator connects the teat cups 19 to the teats of the udder of the animal. The presence of the longitudinal grooves 52 on the levers 3 allows the relative position of the teat cups 19 to vary depending on the morphological features of the udder.

The operator then turns on the milking machine, setting the floats of the sensors 27 to the starting position

using staples 32, and opens the tap k2. In the podskoskovye chambers, the teat cups 19 provide a reduced vacuum, which corresponds to the physiological conditions, since the intensity of the milk yield at the beginning of milking is insignificant. At the same time, the massaging unit begins to work, since the vacuum from the control unit is supplied to the pulsator 37, and from it a variable vacuum is applied to the pneumatic cylinder 33 (the vacuum periodically changing by atmospheric pressure). When a vacuum enters the pneumatic cylinder 33, its piston 5 is retracted, compressing the spring 7 stem 6 t no down the cross 8. 8. The cross 8 carries behind the ends of the levers 3, which ensures that the teat cups 19 and the thermoplate 35 are installed at an angle to the inside of the udder. At this point, there is an intense and deep massage not only of the nipples and bottom of the udder, but also of its sides. When atmospheric air enters the pneumatic cylinder 33, the spring h 7 returns the entire system to its original position. The pulsator 37 is tuned to a frequency of about 15-20 pulses per minute. The tilting angle of the teat cups 19 depends on the magnitude of the stroke of the rod 6, which can be adjusted with the adjusting nut 9. The passage of warm water through the thermoplates 35 has a significant beneficial effect on the animal's mouth, enhances milk flow and more complete production of cows.

As the intensity of the milk flow increases, the floats of the sensors 27 rise to the highest position, and the brackets 32 overturn and the handler starts to control the milking process in automatic mode.

At the end of the milking, the intensity of the milk flow begins to decrease and the control system translates in pairs
