Description

FIELD OF THE INVENTION The invention relates to agriculture, in particular to pulsol collectors.

The purpose of the invention is to increase the efficiency of milking and reduce the incidence of cows.

FIG. 1 shows a diagram of a pulsol collector; in fig. 2 - vacuum supply switch.

Above the milk receiving chamber 1 of the pulse collector, the cover of the milk collection chamber 2 is installed on the threads. The cover 4 of the vacuum distributor 5 is mounted on the lid 2 of the milk collection chamber 1. The tightness of the cavities of chambers 1 and 3 is provided by annular gaskets. In the side of the lid 2 milk collection chambers are installed fittings 5

for milk tubes for teat cups (not shown). The fittings 6 for variable vacuum tubes to the teat cups are installed on the conical sidewall of the vacuum distributor case. When placed obliquely, their axes are parallel to the axles of the unions 5. The lower part of the distributor housing 4 forms the upper half of the chamber of a constant vacuum 3 of the vacuum supply switch. Through the side of the distributor housing 4, the channel h saddle of the constant-vacuum fitting 7 is made. At the upper end of the rod 12 of the switch there is a protrusion-latch 13, tightly fitting in the valve seat i1, having on the sleeve 14

a spring slot, a cylindrical vertical seat with a place for fixing — a latch rod 12. At the bottom 15 of the pulsator 8 there is a central oval hole 16 for sliding the corresponding part of the rod 12.

In the upper part of the housing 4 along the central vertical axis there is a four-stage cylindrical opening. An elastic sealing gasket is installed in the upper stage between the pulsator 8 and the distributor housing 4. In the second stage there is a thrust washer 17. In the third stage there is a plunger 18. In the fourth stage, a seat 19 for the rod 12, The horizontal ends of the plunger 18 are supported on bearings 19. On the outer surface of the plunger 18 there are three annular grooves: the top 20 constant atmospheric pressure is associated with a constant atmospheric pressure chamber of the pulsator 8 through the gap of the opening 16 and the angular opening 21 in the plunger 18; the middle annular groove 22 is made in the form of two different-sized parts: less — atmospheric pressure, greater — vacuum; the lower - annular groove 23 of a constant vacuum is connected by a hole with a chamber 3 of a constant vacuum. Last communicated with constant vacuum nipple 7.

The segments of the middle annular groove 22 are communicated; one with the upper groove 20 and the other with the lower groove 23. With the middle groove 22, 4 variable pressure fittings 6 for teat cups communicate in the distributor case,

The plunger 18 has a hole with a special thread along the vertical central axis. It placed a threaded rotor 24, interacting with the rod 12. The threaded rotor 24 is assembled on the rod (shaft) 12 (Fig. 2). From below it is supported by a sleeve 25 fixed by a retainer. On bearings 5, couplings are mounted: a right-hand 26 and a left-hand 27 rotation, in which there are recesses for bearings.

Pulse collector works as follows. The pulsator 8 informs the rod 12 reciprocating motion. Here, the part of the rod 2 passing through the opening 16 is fixed by an oval engagement from rotation about a vertical axis. When the plunger 18 rotates, its middle groove 23 with two parts passes alternately in the zone of each of the unions 6. Thanks to this, in each of the four milking

the glasses of the apparatus occur alternately in the tact of sucking, and then in compression. The milking of each part of the udder of the cow is carried out alternately.

During the reciprocating movement of the rod 12, the vertical axis is displaced by the vertical stroke of the diaphragm with the pulsator valve, and the overrunning clutches 26

right and 27 left rotation. When moving the rotor with the rod downward stop clutch 26, the plunger 18 rotates in the right direction. At the same time, the clutch 27 on the bearings rotates. During the course

the rod 12 with the rotor upwards locks the clutch 27 of the left stroke and rotates the plunger 12 in the same right side. In doing so, clutch 26 is idling. Thus, when the rod 12 moves downwards and when it moves upwards

the plunger 18 rotates to the right. The middle groove 22 alternately extends at each of the holes in the distributor housing to the variable pressure fittings 6,
