PLOW FOR CULTIVATED ARABLE LAYER CREATION Russian patent published in 2019 - IPC A01B17/00 A01B13/14 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building. Plow to create cultivated arable layer comprises dump shells fixed on frame with dump holes made on dumps, fertilizer compartments with fertilizer lines, high-pressure fan with air pipeline, which is tightly connected to fertilizer lines fixed on rear side of dumps, vertical disk blades installed by means of replaceable brackets. Beyond the disc knife there is a top strap for feeding the upper soil layer with seeds of weeds at the bottom of the furrow. Dump plow body is equipped with device for application of mineral fertilizers into arable horizon and creation of fertile soil layer. Device includes a pressure chamber of a fertilizer tube fixed to the back wall of the dump, which has in the arable horizon location zone the tuyere openings made in the dug at angle of 60…75° to vertical plane. Pressure cavity is tightly connected to fertilizer apparatus, which is an impeller installed on sliding bearings. Axis of impeller is located in zone of pressure pipeline of high-pressure fan, and blades of impeller are located in fertilizer hopper with possibility of gripping fertilizer from bottom of fertilizer bunker, which is inclined to impeller. Behind the dump body on frame with the help of clamp there is a post of soil cultivator-soil-cultivating device, on rear part of which there is material pipeline for supply of amphibians for undercarriage with guides of ameliorant. Material pipeline is tightly connected to the sowing window of the amphibious bunker, which is an ejector of the high-pressure fan. Hopper bottom of the ameliorants has an inclination to the sowing window of the ejector. Pressure pipelines of high-pressure ventilators have adjusting gate valves for regulation of application rate of fertilizers and ameliorants. Drive of high-pressure fans is made from hydraulic motors.

EFFECT: formation of a strong cultivated layer, increased depth of arable horizon and increased crop capacity.
