Abstract

This invention relates to agriculture. The purpose of the invention is to reduce labor costs. The device for automatically turning off the teat cups contains a receiving chamber 2 connected by an inlet 5 with a teat cup, and an exit 7 with a vacuum source. The valve 13 for closing the outlet pipe is fixed on one of the arms of the two shoulders lever 12, and the other arm is provided with a receiving plate 11 located under the calibrated orifice 10 of the additional receiving chamber, made in the form of a funnel. The funnel is installed under the body inlet. The double-arm lever interacts with the pusher 16 of the lever device 19. The double-arm lever 12 has its movement limiter 15. Prior to milking, the lever device is turned, and the valve 13 is retracted from the outlet nozzle 7, connecting the collector vacuum to the podsoskoy chamber of the teat cup. Milk through the calibrated orifice 10 enters the receiving plate 11. When the milking is completed, the valve returns to its original position, blocking the flow of vacuum into the podososkovy chamber. 2 hp f-ly, 7 ill.

Description

The invention relates to agriculture, in particular to devices for automatically turning off teat cups.

The purpose of the invention is to reduce labor costs by reducing the time for turning the teat cups on and off.

FIG. 1 shows a device for automatically turning off the teat cups connected to the teat cups and the collector, side view; on league. 2 shows section A-A in FIG. one; in fig. 3, top view; in fig. 4 - receiving chamber with

side-open flap; in fig. 5 is a section BB in FIG. ; in fig. 6 - receiving chamber with a valve open through a jet of milk; in FIG. 7 receiving chamber with closed valve.

The device for automatic shutdown of the teat cups consists of four receiving chambers 2 installed on a common plate 1, each of which contains a housing 3 connected by rubber tubes 1 by an inlet 5 in the upper part with a milk nozzle of milking stacL

6, and the outlet nozzle 7 in the lower part with one of the four milk pipes of the collector 8. Under the inlet nozzle 5 with its overlap an additional receiving chamber is installed, made in the form of a funnel 9 with a calibrated orifice 10, which is located above the receiving plate 11 attached to the shoulder of the double-shouldered lever 12, the second shoulder of which has a valve 13 at the end. The double-shouldered lever 12 is fixed on the axis, its arms interact with the stop 15 and the pusher 16 of the rotary axis 17 fixed in the housing 3 by means of bearings 18 С n On the outer side of the housing 3, the axes 17 of each receiving chamber 2 are fixedly fixed to the lever device 19. The opposite ends of the rotary axes 17 are connected in pairs by means of levers 20 and axes 21, on which are mounted the ha 22, which connects both pairs of rotary axes 17 to each other . On the common plate 1 there is an abutment 2J, which interacts with a pull 22. The funnel 9 has a bevel of the upper edge directed in the opposite direction from the valve 13.

The device works as follows.

Before commencing milking, the valve 13 blocks the outlet nozzle 7. By turning the lever device 19 and the rotary axis 17 of the actuator into operation, the pusher 16 acts on the double-arm lever 12, sets the receiving plate 11 under the calibrated orifice 10 of the funnel 9, and the valve 13 retracts from the outlet nozzle 7 connecting the vacuum collector 8 to the podoskovoy chamber of the teat cup 6.

The milking process begins. Milk through the calibrated orifice 10 begins to enter the receiving plate 11, as a result of which the double-arm lever 12 moves to the extreme open position of the valve 13 to the limiter 15. By turning the lever 19 by 180 °, the pusher 16 moves away from the double-arm lever 12 and under the action of a continuous stream of milk the valve 13 held in the open position. The excess milk, which did not have time to pass through the calibrated hole 10 during the sucking stroke, is poured through the bevel of the upper edge of the funnel 8 onto the receiving plate 11.

At the end of the milking and the cessation of the impact of the milk jet on the receiving plate 11, the valve 13, overcoming the adhesion of the two shoulders lever 12 to the stopper 15 and the friction of the axis 1 about the body 3 lowers and closes the outlet nozzle 7, stopping

c vacuum action on the teat chamber of the teat cup 6.
