SOWING MACHINE FOR SOWING GERMINATED SEEDS OF VEGETABLE AND GOURD CROPS Russian patent published in 2022 - IPC A01C7/16 

FIELD: agriculture.

SUBSTANCE: seeding machine for sowing germinated seeds of vegetable and melon crops contains a housing, a drive shaft with an asterisk and bearings, a seed box in the form of a sealed semicircular chute tapering towards the bottom, in which a vertical disk is placed on the drive shaft. The vertical disk has cells in the form of seeds of the sown crop in the form of spoons with holes located on the holders. A catcher with a seeding window is installed on the body. Inside the catcher in the middle part there is an additional shaft on plain bearings, having a driven chain drive sprocket connected to the drive sprocket located in the middle part of the drive shaft. The number of teeth on the driven sprocket is less than on the leading one. On the outer surface of the additional shaft installed inside the catcher, there is a cylindrical brush, the diameter of which corresponds to the length of the catcher, and the length corresponds to the width of the catcher. The cylindrical brush is made of flexible bristles, the material of which has low hardness, and the diameter is no more than 0.3 mm. Each holder with spoons is rigidly fixed to the vertical disk by means of a bolted connection in such a way that the holders are inclined relative to the radius of the vertical disk at an angle α, in the direction opposite to its rotation. The length of the holder is such that the gap δ between the spoons and the bottom of the seed box is 4-5 mm greater than the value of the two sizes of the largest sown seeds.

EFFECT: use of the invention makes it possible to improve the quality of sowing germinated seeds and obtain friendly shoots by reducing damage to seed sprouts.
