摘要：
FIELD: agriculture.SUBSTANCE: invention relates to the agricultural machinery industry, in particular to drills for ridge drilling of tilled crops. The ridge drill comprises ridge formers 4 fixed to the frame 1, sowing units 2, packing wheels 3. The ridge formers 4 contain a rack 5, an A-hoe blade, a moldboard and a bracket. The bracket is mounted on the rack 5. On the bracket an adjusting disc with an axis is rigidly fixed. Under the adjusting disc an additional disc is mounted with the ability of rotation about its axis. The adjustment and the additional discs have holes located on the periphery at the same distance from their center. Under the additional disc a guide bracket is rigidly attached, having a semi-axis and a moldboard 15. The moldboard 15 is made flat and is mounted on the semi-axis with the ability to change its position on height along the rack with respect to the cutting edges of the A-hoe blade and the impinging angle in the horizontal plane, as well as fixing in the desired position. The moldboards 15 of each pair of the ridge formers 4 are mounted symmetrically with respect to the line of the seeds sown at an angle which aperture is directed towards the ridge drill movement. The packing wheels 3 comprise a frame, spherical discs 25, packing rings 29, an axis 28, a bar 30 with a spring 31, and located behind the ridge formers 4.EFFECT: invention enables to improve the quality of planting tilled crops and the formation of soil ridges over the seeds sown.5 dwgИзобретение относится к сельскохозяйственному машиностроению, в частности к сеялкам для гребневого посева пропашных культур.
