Theoretical substantiation of the form of working separator bodies at pre-sowing stone soil treatments

Abstract

The article discusses a method for planting seeds in stony soil and a device for its implementation. It has been established that the quality of seed placement in the soil significantly depends on the quality of formation of the earthy soil layer at a depth of seed placement. A method is proposed for planting seeds in stony soil, which includes cutting off the upper layer of stony soil with its simultaneous separation, formation of stony and fine-grained layers from it and laying them alternately on top of each other, forming grooves, laying seeds on its bottom and falling asleep seeds with soil. In contrast, the depth of cut of the upper layer of stony soil is taken equal to the sum of the depth of seeding and the maximum size of stones. To implement the method, a proposed device includes a frame, a ploughshare mounted on it, and a separating grid made of several parallel wire elements, sowing machines, disc coulters, and fenders. The economic efficiency of the proposed technical solution is associated with maintaining the period of the emergence of seedlings and, accordingly, increasing the yield of crops, as well as increasing the productivity of sowing machines.
