Description

The utility model relates to agricultural machinery, in particular to disk coulters for sowing crops.

Openers are the second main working body of grain seeders. They serve to create grooves in the soil and to lay seeds and fertilizers on its bottom. The appearance of uniform friendly seedlings and the development of plants largely depend on the quality of the coulters. The coulters must create the same furrows of a given depth, do not take out the lower soil layers on the field surface so that there is no loss of moisture, compact the bottom of the furrow to renew capillaries in the soil, ensure even distribution of seeds in the furrow, and sprinkle them with a moist soil layer. The most common type of openers is a double-disc single row (regular) opener.

The coulters are a molded case with two flat pointed discs. They converge at the front of the coulter, forming a wedge in plan with an angle of approximately 10 °. The discs are bolted to the chassis. Rubber seals are installed between the case and the discs. A leash and a bell are attached to the front of the housing ridge, and a scraper and a seed guide are located between the disks at the back.

When moving the coulter, the discs roll, cut and wedge the soil to the side, forming a groove. Seeds from the vas deferens through the socket fall onto the guide and slide to the bottom of the groove. Disks before laying seeds hold the groove walls from shedding.

All double disc coulters are equipped with an additional roller for setting the depth, which also performs the function of seeding the grain. The standard equipment sometimes includes tines.
