SYSTEM OF LIQUID FERTILISERS DISTRIBUTION OF COMBINED AGGREGATE FOR SOIL PROCESSING AND LIQUID FERTILISERS APPLICATION Russian patent published in 2009 - IPC A01B49/06 A01C23/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine-building, in particular to technical means for intra-soil and superficial root and non-root additional fertilisation of plants with liquid fertilisers, plant spraying, processing with pesticides with simultaneous soil tillage, mechanical destroying of weeds, earthing up plants. System contains reservoirs for liquid fertilisers installed on support sites, containing primary screen filters with hydraulic mixers and respiratory labyrinth valve, located in filling neck of the reservoirs, funnel-suppressor, installed in reservoir bottom and jet mixer located in lower zone of reservoirs, and connected with replaceable sprayers, located on non-working back surface of chisel-shaped colters by means of pipelines and check valve through successively located low-pressure filter, membrane pump and regulator-distributor. System has pipelines of reverse solution supply and additional branch of pipelines with three-way tap, connected with input end with membrane pump, connected with the first output end through T-joint with hydraulic mixer of primary screen filter and jet mixer, and with the second end connected with pipeline of reverse solution supply. Hydraulic mixer is located in upper zone of primary screen filter and includes input branch pipe, connected with three-way tap and connected in T-like way to located in primary screen filter distribution pipe with installed on its free ends at acute angle to it supplying nozzles. Regulator-distributor includes reducing pressure valve connected through high-pressure filter with output branch pipes of distributing valve for supply of solution to sprayers of chisel-shaped colters, and manometre. Regulator-distributor is connected through input branch pipe with membrane pump, through output overflow branch pipe with pipelines of reverse supply of part of solution into reservoirs for liquid fertilisers and is equipped with handle for turning on regulator-distributor and handle of pressure regulating. High-pressure filter is equipped with outlet branch pipe for removal of filtered fraction.

EFFECT: invention solves the problem of reduction of material consumption by the system, extension of functional abilities of aggregate, increase of its productivity and versatility, increase of aggregate performance efficiency with simultaneous soil processing, destroying weeds and additional fertilising of cultivated crops.
