AUTOMATIC DEVICE FOR APPLICATION OF LIQUID FERTILISER TO IRRIGATION WATER Russian patent published in 2013 - IPC A01C23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for application of fertilisers and chemicals with irrigation water. The device comprises a container, the working cavities of the metering pump coupled by the piston and connected to hydraulic motor. The device is provided with a spring synchro-pusher, which consists of two blocks of spring pusher and a slide - water distributor. The synchro-pusher is provided with a fixed carcass-frame. The carcass-frame is mounted on the opposite side of the hydraulic motor power piston and is connected with moveable axis of the guides. The housing is made as a fixed carcass with support axes. The support axes are interconnected by spring-loaded stop block of the movable axis of the carcass-frame. The movable axis of the carcass-frame is connected by the rod with the possibility of deviation of the rods from the neutral unstable equilibrium in the range of 3 to 7 degrees. The moveable axis is mounted with a movable eye with the adjusting screw. The movable eye is connected to the axis of the slide - water distributor.

EFFECT: use of the present invention enables to improve operational reliability and to increase the efficiency of the hydraulic motor in operation of the hydrodynamical connection of a moving stream with movable elements of the metering pump.
