Abstract

The pre-sowing treatment of seeds in a magnetic field makes it possible to increase the yield of crops, reduce their incidence and improve the quality of agricultural products.

Pre-sowing treatment of seeds should be carried out in a periodic magnetic field with a magnetic induction in the center of the air gap of 0.065 T with a fourfold re-magnetization, pole division of 0.23 m and a seed velocity of 0.4 m/s.

The conveyor drive must ensure the optimum value of the conveyor belt speed as it affects the time of the seed treatment in the magnetic field.

Voltage deviations along with the loading of the conveyor affect the change in the angular velocity of the conveyor motor.

The purpose of the study was to determine the effect of voltage deviation on the change in speed of conveyor belt.

When the voltage is deviated, the torque of the asynchronous motor changes in proportion to the square of the voltage.

The moment of static resistance of the conveyor does not depend on the angular speed, but is directly proportional to the density of the material being transported.

Based on theoretical studies, we have obtained an analytical expression that relates the speed of the conveyor belt to the deviation of the voltage at the motor stator and the density of the transported material.

It is established that the conveyor of the electrotechnological complex for pre-sowing seed treatment in a magnetic field changes the speed of movement of the conveyor belt inversely proportional to the square of the voltage deviation and directly proportional to the density of the transported material.

By reducing the voltage by 5% and rated engine load, the angular motor speed decreases by 1.8%, the minimum load - 2.8%, the maximum load - 1%.

Key words: magnetic treatment, seeds, conveyor, electric drive, voltage deviation, conveyor belt speed
