SHARE FOR SUBSOIL BROADCAST SOWING OF FARM CROP SEEDS Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: share has cultivator hoe, tine, seed guide and seed distributor located under hoe. Seed distributor is made in the form of wings with symmetrically bent lines. Wings are spread apart in opposite directions, and their surfaces are bent in parabolic lines. Wings are formed as parallelograms and curved in transverse-horizontal plane. Seed guide is manufactured from caprone and is equipped with self-adjusting ring equipped with baffle. Seed distributor base is arranged in vertical plane, symmetrically and perpendicular to axis of direction of share advancement. Lower and upper surfaces of seed distributor are extending in horizontal plane. Lower part of seed distributor is tapered symmetrically to bending line at an angle α =75-80 deg with respect to lower base of seed distributor. Wing spreading angle in upper part of seed distributor is equal to wing spreading angle in lower part of seed distributor. Seed distributor wing surfaces are inclined forward in direction of advancement of share. Self- adjusting ring with baffle is mounted on seed guide through ball bearing. Baffle working surface is extending in horizontal plane, below horizontal diameter of self-adjusting ring opening. EFFECT: increased uniformity of seed distribution in the process of advancement of share traverse to slopes during occurrence of transverse vibrations and on horizontal surfaces. 5 cl, 4 dwg
