A mock-up sample of the dispenser of the seeding device of the selection seeder as part of the laboratory stand was developed. The MG995 servo drive is used as a drive for the seeding machine dispenser. The experimental stand includes a conveyor belt that simulates the process of moving a planter. The drive of the conveyor belt is a stepper motor SY42STH38-1684A.
The numerical modeling factors are the diameter of the seed Dμ (0.001–0.003 m), the angle of rotation of the flap α (0.3489–0.8028 rad), the time interval when the flap is open or closed Δt (0.2–0.4 s), the speed movement of the conveyor belt (planter) V (1–4 m/s). Quantitative evaluation criterion is seed sowing rate N. Qualitative evaluation criterion is sowing accuracy δ.
As a result of experimental studies of the dosing device of the selection planter of small-seeded crops, the dependences of the seed sowing rate N and sowing accuracy δN on the average effective seed diameter Dμ, the flap rotation angle α, the time interval when the flap is open or closed Δt and the movement speed of the planter V for three options were established the shape of the holes.
A visual and statistical comparison of theoretical and experimental dependences testifies to the adequacy of the obtained theoretical models and the reliability of the obtained experimental regularities.
It was established that the accuracy of seeding δN for the 1st version of the hole (triangle) of the metering unit of the sowing device is in the range of 78.0–99.9%, for the 2nd version (semicircle) the range is 71.1–98.3%, for the 3rd version (rectangle) range 67.3–97.4%. Therefore, taking into account the theoretical conclusion and the obtained experimental data, in further studies we accept the 1st version of the holes (triangular).
