DEVICE FOR INTRASOIL DIFFERENTIATED APPLICATION OF LIQUID MINERAL FERTILIZERS AND PESTICIDES Russian patent published in 2022 - IPC A01C23/02 A01C23/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The device for intrasoil differentiated application of liquid mineral fertilizers and pesticides contains a control unit, a unit for placing and supplying working fluids, a unit for regulating the supply of working fluid, a unit for dosing and distributing the working fluid, and a unit of working bodies. The dispenser-distributor of the dosing and distribution unit of the working fluid is equipped with a receiving chamber (48), dosing chambers (49) and distribution of the working fluid (50), made coaxially with the vertical axis of symmetry (a-a) of the dispenser-distributor. The receiving chamber (48) is connected on one side by a hydraulic line to the working fluid supply control unit, on the other side - to the dosing chamber (49) by inlet dosing holes (51), each of which has an effective flow area, starting from the smallest, twice as large as the previous one. The outlet of the dosing chamber (49) is connected by a conoidal channel (53) to the working fluid distribution chamber (50). The chambers for dosing (49) and distribution of the working fluid (50) are made in the form of spheroids of rotation oblate along the vertical axes, coaxial with the vertical axis of symmetry (a-a) of the dispenser-distributor. The receiving chamber (48) is made in the form of an internal cavity formed by the upper (61) and equidistant lower (62) surfaces, flattened along the vertical axis of the spheroids of revolution, truncated along the horizontal axis (b-b). The device for cleaning the outlet pipe of the working body is made in the form of a spiral-screw axisless elastic screw, attached at one end to a freely rotating sleeve mounted on an axis fixed at the end of the outlet pipe, and with a free second end emerging from the cavity of the pipe at a distance from the end of the pipe, along at least not less than the length of the pipe.

EFFECT: improved efficiency and quality of device operation.
