MACHINE WITH ACTIVE BED FORMERS FOR POTATO PLANTING FOR SEEDS Russian patent published in 2020 - IPC A01C9/04 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building and can be used for formation of loosened soil with simultaneous planting of sprouted and non-sprouted calibrated potatoes with preset pitch and depth of potato tubers. Machine for potato seed planting with active bed formers comprises a bin with an inclined bottom, in which adjustable flaps are located, which control the gap to the feeding ladle. Vibratory plates and agitators are installed in the ladle, as well as spoon-disk planting device with spoons, to which fingers of clamps are spring-loaded with fixation in lower part of spoon-and-disk upsetting apparatus and loosening when approaching the tuber pipe. Latter is connected with a ploughshare, to which a fertilizer tube is also fixed. Working elements of the seeding apparatus are driven by the PTO of the tractor by means of a small reduction gear and a chain gear. Rotary cutter with blades and a housing is installed ahead of the ploughshare in the direction of movement, which is fed from the tractor power take-off shaft through the main reduction gear and rotates in the opposite direction to the machine movement. At that, the upsetting apparatuses have a range of adjustment for the width of the row spacing of 50–75 cm. Immediately behind the rotary cutter there is a grid equidistantly installed, consisting of horizontal rods with diameter of 13 mm at distance of 50 mm from each other. Behind the protective casing a shield is installed, which is made in the form of the required profile of the ridge, behind which the packing roller is installed, to the frame there fixed are support wheels and registration wheels, closing discs, as well as an automatic coupling system.

EFFECT: invention will make it possible to combine operations of loosening of soil, formation of ridges and planting potatoes on seeds in a row with planting apparatus with adjustment of distance between them in range of 50–75 cm.
