STAND FOR IMITATION OF THE WORK AND TESTS OF THE AIR FLOW RELEASE SWITCH IN THE MILKING MACHINE Russian patent published in 2018 - IPC A01J7/00 G01M3/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to milking equipment for dairy farming. Stand includes a frame (1) with a stand (2), on which a geared motor (3) is mounted. Drive shaft (4) of the geared motor contains a crank (5) with the connecting rod (7) attached to it by means of a hinge (6). Connecting rod is connected via a hinge (8) to the link (9) mounted on the shaft (10). To the opposite end of the shaft is attached a telescopic lever (11) with an insert (12) movable relative to the housing (13) with a screw (14) and fixing in a new position with a nut (15). Insert is provided with a hinge (16) by means of which a variable length pull rod (17) with a lock (18) is attached to it. At a time, second end of the rod is attached to the rod (20) mounted in the guide (21) by means of a hinge (19). Rod is attached to the frame (23) with a screw (24) by means of a strain gauge force sensor (22) to fix the test slider (25) of the airflow switch (26). Switch also includes a base (27) with grooves (28–30) and a base (31) with a spigot (32), connected to a source of vacuum pressure and nozzles (33, 34) for tapping the switched air flow, combined with the slots of the base.

EFFECT: improves the simulation of the operation and the test of the pulsator air flow switch of the teat cups.
