Optimized upper disk plow design for efficient cotton field cultivation

Mass application of serial two-tier plows fails to meet agricultural technology requirements for processing cotton fields. This study aims to develop plows for effective cotton field plowing with stalks present. A plow with main bodies and upper disk working bodies featuring a blade-type device is proposed. Experiments using a laboratory and field installation determined the completeness of cotton stem sealing, depth of stem embedding, and traction resistance. Theoretical studies suggest a 45 cm coverage width for main bodies and a 23.3 cm longitudinal distance between main and upper discoidal working organs. Experimental results indicate that a spherical disk with capsize as the upper working body ensures optimal burial of cotton stalks. At speeds of 6-9 km/h, the burial rate exceeds 95%, with a depth greater than 15 cm.
