FIELD: agriculture. ^ SUBSTANCE: disc ploughshare comprises a pole with a seed channel which is rotatably mounted on a carriage by a bearing. The pole is equipped by a cutting disc with a central hole matched with the pole channel. A conical seed scatterer is fitted on the lower disc surface. The scaterer and the channel form an annular gap for the seeds to pass between the scaterer conical surface and the pole end face surface. The disc ploughshare is additionally equipped by distributing elements. The distributing elements are fitted on the lower disc surface around the seed scaterer. The distributing elements are set in at least two rows spaced from each other and from the scaterer and with gaps between the elements in each row. The gaps between the elements in the inner row are overlapped by the elements of the outer row. The distributing elements can be made as plates or pins of cylindrical, rectangular, oval form which are set uniformly in chequerwise order. ^ EFFECT: such design provides for even introduction of fertilisers or fertilisers and seeds on the whole width of the field treated. ^ 18 cl, 6 dwg |
