Usually, the planting seedlings for terrain reforestation require a lot of manual labour and high number of workers, in order to minimize these requirements it is necessary to use a mechanical system serviced by minimum two qualified workers to carry out the planting holes. In this way the soil drilling equipment can be used in horizontal ground and also on slope terrains (max. 15º). This mechanism had been designed with an innovative drilling orientation system, which has the possibility to execute vertical planting holes. The kinematic analysis of the soil drilling mechanism was made using dedicated numerical modelling methods and simulation using MATLAB software applied on a specific R-RRR mechanisms that can be used to accurately reproduce the functioning of the experimental model developed by INMA Bucharest. Keywords: kinematic analysis, soil drilling mechanism, innovative afforestation technology, degraded land, sloping terrain. Introduction In the paper the kinematic analysis of the soil drilling equipment used for slope terrain afforestation is presented. This is a novelty element in the frame of the innovative afforestation slope terrain technology developed by INMA, see Fig. 1, which can realize vertical planting holes even on inclined degraded lands and in this way the seedling development period is decreased, it increases their grip and ensures high development uniformity of the planting material [1]. Fig. 1. Afforestation innovative technology An advantage of this equipment is that it can be used in aggregates with high power motocultivators (19 HP) and low power tractors [2], power sources adequate in hard working conditions, (as degraded lands: water and wind eroded land, land displacement phenomena, land with excess water, salty land, degraded land and anthropogenic landfills, land stripped and artificial embankments) in order to conduct technological works safely and with stability.
