Abstract

This invention relates to agriculture. The purpose of the invention is to simplify the design and ensure the simultaneous termination of milk removal from both parts of the udder. A pneumatic pulse generator consists of a main and an additional pulsator acting on the front and rear parts of the udder. The pulsator contains constant vacuum chambers 1 and 2, membranes 3 and 4, valves 5 and 6, control chambers 7 and 8, alternating vacuum chambers 9 and 10, channel 11 for supplying atmospheric pressure. Control chambers 7 and 8 are interconnected by connecting tube 16, and variable vacuum chamber 9 is connected to tube 16, in which throttles 14 and 15 are installed. When valve 6 closes channel 11 in chamber 10, a vacuum occurs and a sucking stroke occurs that acts on the rear share udder. When the valve 5 overlaps the channel 11 in the chamber 9, a vacuum is created and a sucking stroke occurs, affecting the front parts of the udder. Pneumatic generator works in pairwise milking. 1 il.

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

The purpose of the invention is to simplify the construction and to ensure the simultaneous termination of milk removal and both parts of the udder.

The drawing shows a pneumatic generator, a general view.

The pneumatic pulse generator of the milking machine consists of main and additional pulsators, having constant vacuum chambers 1 and 2 and diaphragm 3 and 4, valves 5 and 6, control chambers 7 and 8, variable vacuum working chambers 9 and -10, channel 11 for atmospheric or overpressure supplies, nozzles 12 m 13, droshbel 14 and 15 and connecting tube 16,

A constant vacuum chamber 1 is separated from the control chamber 7 by a membrane 3 connected to a valve 5 located in the variable vacuum working chamber 9 having a branch pipe 12. The branch pipe 12 communicates with the control chamber 7 via throttles 14 and with the control chamber 8 through the tube 16 and the throttles 15. A constant vacuum chamber 2 is separated from the control chamber 8 by a membrane 4 connected to a valve 6 located in the variable vacuum working chamber 10 having a nozzle 13 and a channel 11 for supplying atmospheric or excessive pressure.

Pneumatic generator operates as follows.

When vacuum is created in constant vacuum chambers 1 and 2, the valves block channel 11 for supplying atmospheric or overpressure due to atmospheric pressure of control chambers 7 and 8, moving diaphragms 3 and 4, connected to valves 5 and 6. In working chambers 9 and 10, a variable vacuum is created, a vacuum is created, and a suction stroke occurs. A vacuum is created in the tube 16 of the port 12. Since the choke 15 has less resistance, the necessary vacuum is created in the control chamber 8 earlier than in the control chamber 7, since the choke 14 has a greater resistance. Therefore, the movement of the valve 6 through the membrane 4 occurs faster than the movement of the valve 5 through the membrane 3. When the valve 6 closes the channel 11 for supplying atmospheric or excessive pressure in the working chamber 10 of an alternating vacuum, a vacuum occurs and the suction stroke affects the rear udder sections. Then, by overlapping the valve 5 of the channel 111 in the working chamber 9 of an alternating vacuum, a vacuum is created and a sucking stroke occurs, affecting the front parts of the udder. Air is sucked from the tube 16 and the cycle repeats. The choke 14 set the desired frequency of pulsation. The choke 15 sets the required ratio of cycles occurring in the working chamber 10 of variable vacuum.

The pneumatic pulse generator of the milking machine operates in a pairwise mode.
