ROWLESS COLTER FOR SUBSURFACE BROADCASTING Russian patent published in 2019 - IPC A01C7/20 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machinery, in particular, to colters for subsurface spreading of seeds and fertilizers. Rowless colter for subsurface spreading includes a tubular hollow stand-drill tube, a tip in the form of a thinning blade with a support sole and distributor of sown material installed in the colter at a small height. At the same time, cutting disks fixed at an angle of crumbling to the bottom of the furrow and placed in series with the overlapping of the front subsequent disks are fixed on the leading edge of the tip with rolling bearings on the shafts. Tubular hollow stand-drill tube, located behind the support sole, made in the form of a chisel working body. Distributor is made in the form of a flow divider of bulk materials of pneumatic seed drills, in which the working surface of its dividing head has a generating line, which is a part of the logarithmic curve, smoothly connecting the central inlet channel with outlet nozzles directed along the movement of the colter to the cutting disks. Distributor is located under the outlet of the tubular hollow stand-drill tube, and its central supply channel is located inside it.

EFFECT: invention will improve the uniformity of the seeding material embedment in depth and its distribution through the outlet nozzles without damage and sticking it on the working surface of the dividing head.
