Abstract
The study carried out on the qualitative indicators of work for planting seedlings requires knowledge of the cyclogram of the operation of the cup of the planting device.This involves knowing and correctly setting the operational phases of the bucket at a full rotation of the distributor disc.The realization of the cyclogram takes into account the kinematic elements of the transmission that determine the peripheral speed of rotation of the cup and influence the time of placing the seedling in the cup by the user.Consisting of several sectors, namely the sector of placing the seedling in the cup, moving the seedling cup until it opens and leaving the seedling in the ground, moving the open cup without seedling, closing the cup for feeding the seedling by the user, mainly influences the distance between the plates at a time.At the same time, the peripheral speed of rotation and the times for completing the operational phases of the cup have an influence on the state of fatigue of the user, in the conditions where an experienced user can place 60-70 seedlings/minute.Following the conducted research, conclusions were drawn on the operation of the planter with different number of cups at different work speeds on the achievement of the respective work quality indices: the distance between plants in a row, the position of the plant in the soil. The obtained results led to observations for the optimization of the cyclogram.
