PLANT FOR AUTOMATIC WATERING OF PLANTS Russian patent published in 2020 - IPC A01G27/00 

FIELD: plant growing.

SUBSTANCE: invention relates to plant growing and can be used for drip irrigation of greenhouses and gardens. Proposed plant comprises metering tank with outlet branch pipe to drain water into water distribution system, automatic float valve with air outlet/inlet branch pipe and pipeline with shutoff valve for water supply. Air outlet/inlet branch pipe is located in the center of the gate surface with water discharge/inlet branch pipes symmetrically placed in its cavity. Float gate is installed with possibility of movement along height on hollow guide posts connected by one end to bottom of chamber, and by another – to chamber cover. Air outlet/inlet pipe is connected to bellows, which upper end is connected to lower part of branch pipe, fixed in cover, with connection to it of small impeller for supply of air under pressure to gate. Dosing tank is equipped with a vertical wall, a discharge siphon and an air tube for air discharge from the chamber. Siphon is installed in the upper part of the wall separating the metering tank into two chamber sections, one of which is sealed with a siphon and a branch pipe for draining water into the water distribution system. Operation of closed chamber is controlled by means of control unit with electronic-switched circuit and connected to it electromagnetic sensors of water level monitoring in chamber. Source of compressed air in form of impeller is connected to control unit, slide mechanism is installed with possibility to communicate cavity of chamber with atmosphere and is connected by control input through electromagnet with program unit, which inputs are connected to level sensor, and output with small impeller. Unit is equipped with setter of periodical periodicity of spool opening and closing.

EFFECT: higher reliability of the plant due to control of water level in the chamber.
