Abstract

This invention relates to agriculture. The purpose of the invention is to simplify the design and increase the reliability of the pulsator. The pulsator consists of a housing 1, a spring 2, an adjusting screw 3, membranes 5 and 6. The valve 7 is fixed on the stem, which is connected to the membranes 5 and 6. With an increase in milk flow, the pressure in chamber 14 delays the switching of valve 7 to the upper position, which increases duration of tact suck. With a decrease in milk flow, the vacuum in the chambers 14 and 9 of the pulsator levels out, the duration of the sucking stroke decreases. By precompression of the spring 2, the required initial ratio of the milking cycles is established. 1 hp ff, 1 ill.

The invention relates to agriculture, in particular, to pulsators and dowsing machines.

The purpose of the invention is to simplify the design and increase the reliability of the pulsator. .

The drawing shows a diagram of the pulsor of the milking machine.

The pulsator consists of body 1, two guns 2, adjusting screw 3, pore washer 4, membranes 5 and 6, claan 7, channel 8. In case 1, there are: constant vacuum chamber 9, main vacuum chamber 10 –15, additional variable vacuum chamber 11, constant atmospheric pressure chamber. 12, main control chamber. 13, additional control camera 14, 20

Pulsator milking apparatus operates as follows.

The pulsator is connected to a vacuum line (not shown), air is evacuated from chambers 9-11 - this corresponds to the suction stroke. After installing the teat cups (not shown), the teats of the pulsator chamber 14 communicated with the collector (not shown) will have the same vacuum as the JQ chamber 9. During this period, valve 7 is subject to spring preload pressure 2 and air pressure from the chamber 13 to the annular part of the membrane 5 in the direction of the chamber 11.

With the beginning of the stroke, the air from chamber 13 through channel 8 is pumped out to chamber 11, in which there is discharge during this period. The pressure from the side of the chamber 13 decreases, from the side of the chamber 12 to the side of the chamber 13 increases. At the moment when the pressure from the chamber 12 to the side of the chamber 13 exceeds the compressive force of the spring 2, and the reduced pressure from the chamber 13, the valve 7 rises. Camera 9 is uncoupled

chambers 10 and 11, and the latter communicate with chamber 12. During this period, atmospheric pressure flows into the inter-wall chambers of the teat cups, which corresponds to the compression stroke.

When air enters the chamber 13, the pressure in it decreases until the pressure of the spring 2 and the valve 7 is lowered and the suction stroke begins to repeat.

 As milk flow increases, the pressure in the reservoir increases, and the pressure in the chamber increases.

14 pulsator. This pressure depends on the amount of milk given during the milking cycle. As the pressure in chamber 14 increases, an additional force arises from the side of chamber 14 towards chamber 9 on membrane 6, which delays the switching of valve 7 to the upper position and thereby increases the suction stroke.

With a decrease in the intensity of the milk flow, the vacuum in the chambers 14 and 9 of the pulsator levels out and the duration of the sucking stroke decreases. To take into account the individual characteristics of the animal, the preliminary initial compression of the spring is established by preliminary compression of the spring 2.
