OPENING PLOW SECTION OF SOWING MACHINE Russian patent published in 2014 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, in particular to sowing machines for cultivated, vegetable and cucurbits crops. The section comprises a drill tube, a disc knife, a furrow-forming device and a press-wheel coverer. The disc knife is made in the form of a flat ring with bearing ribs in the form of hollow cylinders. The disc knife with the bearing ribs, serving as a gauge wheel, is mounted on a leash adjustable in height, which axis is placed on the bracket of the parallelogram linkage of the section. Behind the disc knife in the lower rear quarter the moldboards are mounted on a height-adjustable rack to remove dry layer of soil. In the cross-section of the moldboards on the height-adjustable rack the furrow-forming device is mounted in the form of truncated cones oppositely mounted with the large bases with an angle of inclination of the generant to the base of 25-30°. Behind the furrow-forming device a drill tube is mounted. On the adjustable leash a press-wheel-fixing coverer is mounted. The coverer is made in the form of the truncated cones oppositely mounted with the small bases with an angle of inclination of the generant to the base of 25-30°. Behind the coverer the coulter-harrow is provided.

EFFECT: constructive implementation enables to improve seed germination and productivity due to providing a predetermined depth of seeding-down and covering them with soil moist layer, and reduce costs for handling of plants.
