SOWING DEVICE FOR DOTTED-CLUSTER SOWING OF SWOLLEN AND HATCHED CUCURBITS CROPS SEEDS Russian patent published in 2016 - IPC A01C7/16 

FIELD: agriculture.

SUBSTANCE: sowing device comprises encased stirrer vertical sowing disk, in which there are through cells for seeds and ejector in zone of discharge window. Bottom of seed box is inclined to sowing disk at angle of 50…60° to vertical plane. Lower part of bottom is conjugated with vertical sowing disk, installed on drive shaft. Latter rests on sliding bearings arranged on side walls of seed box. Sowing disk is fixed on drive shaft by square. On external periphery of sowing disk cells are made, arranged in groups, with number of cells in group, equal to number of seeds, sown into seat. Cell parameters correspond to dimensions and shape of sown crop seeds. Outer part of cell at side of seed box is open for retraction of seeds. Value of outer open part of cell is 0.5 l_max, where l_max is maximum length of sown crop seed. Inner part of cell is rounded by radius, corresponding to radius of curvature of sown crop seed section length - width. Besides, sowing disk is arranged relative to vertical wall of seed box with possibility of rotation, cells are arranged on disk periphery at angle of 25…30° relative to radius of rotation. Lower inner part of cell has rounding along radius of seed circle in section length-thickness. In upper part of seed box in vertical wall discharge opening is made, located above level of seeds in seed box. Opposite to unloading window on axis elastic seed pusher is made. Discharge opening is braced by seed tube with seeder ploughshare.

EFFECT: invention provides production of seats with mutual seeds removal from each other at distance of 3…5 mm to prevent their damage by pests, which improves field germination and yield of sown crops.
