MECHANISM FOR ATTACHMENT OF ROLLING WHEEL TO SOWING MACHINE Russian patent published in 2024 - IPC A01C7/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention is intended to ensure packing of sown rows and can be used on sowing machines of any design. Rolling wheel to sowing machine attachment mechanism comprises: rolling wheel 2 stilt 1, arranged on horizontal axis 3 in hub fixed on gusset plate, rolling wheel 2, spring 9 of adjustable stiffness, bracket 7. Gusset plate is attached to bracket 7 by means of vertical hinge 6, and stilt 1 of rolling wheel 2 protrudes beyond its attachment to horizontal axis 3 and has flat horizontal foot 8 at the end of projection. Pressing spring 9 is arranged in cantilever on tightening pin 15. At that, between horizontal foot 8 and pressing spring 9 there is clamping tab 10 with slots fixing its location, overlapping by its plane the flat horizontal foot 8 of stilt 1 of rolling wheel 2, as well as the end part of the gusset plate, and entering the gusset plate with slots. On flat horizontal foot 8 of stilt 1 of rolling wheel 2 with an offset to one of its sides there is a hole for attachment of tightening pin 15 of pressing spring 9. On clamping tab 10 there is a hole for tightening pin 15 of pressing spring 9. Above the hole for pin 15 of pressing spring 9 there is a branch pipe.

EFFECT: use of the invention will make it possible to increase the quality of soil compaction and accuracy of the wheel guiding along the sowing line.
