Kravchenko V. The Intensification of the Berry Bushes Recycling Process on a Plantation

The thesis is devoted to the intensification of the berry bushes recycling process on the plantation. The recycling process which combines grinding branches and roots of bushes simultaneously putting them into the soil has been theoretically grounded by the technological scheme and unit’s parameters. A consistent rational degree of grinding process which consists of hammer separation branches with the partial chopping them into small pieces with these hammers, then dividing branches and roots with the crushable knives into pieces according to the agrotechnical requirements and putting them finally into the soil have been proposed in the research. Being based on the theory of probability, the relationship between the grinding degree of branches and mill cutter’s parameters has been defined. The rational grinding degree of branches by hammer drums and the mill cutter’s knives ensuring minimal power consumption has been also reflected. The influence of basic kinematic and geometrical parameters of hammer drum operation on the crushed branches pieces length has been revealed. The hammer’s weight and geometrical sizes in the process of grinding branches, balancing it on the hit and balancing the hammer drum’s system have been determined in the investigation. On the basis of theoretical and experimental studies, the investigated unit’s prototype has been done. Using the created unit for the intensification of the berry bush recycling process on the plantation will provide cost savings in compare with using the mill cutter SHMC 1,5 (Swamp Hinged Mill Cutter) – for 205 hryvnias per hector.
