Sarana V. Substantiation of basic parameters of grinding down for branches of high density fruit orchard

The object - process of branches shallow got after crown cutting of high density fruit orchard, machine for branches shallow and its working organs. The purpose -increasing of efficiency of branches utilization of fruit-trees in high density fruit orchard by the improvement of mechanization facilities for their shallow. The methods - Аnalytical and experimental methods of technical researches with the use of basic positions of agricultural mechanics, theoretical mechanics, resistance of materials, mathematical planning of multifactor experiments and mathematical statistics. The results of researches were processed on computer by means application programs STAT (SAC "IMESG" UAAC) and STATISTICA-6.The novelty - 1. Substantiated and developed mathematical model of co-operation process of hammer with a branch at a central and uncentral transversal feat, the analysis of which enables to define the size of hammer destructive speed. 2. In constituents of balance power are theory ically defined and experimentally specified and influencing on them basic parameters of process of shallow for mobile grinding down branches. 3. Rational structural parameters and kinematics modes of grinding down operations with the purpose of providing of minimum specific energycapasity and high-quality indexes, that answer agrotechnic are experimentally specified. Outcomes of the research. Technological chart is developed and structural parameters and rational modes of operations of mobile single-stage grinding down branches are scientifically substantiated. Results of scientific researches have been given to Institute Gardening of UAAC and they will be used for planning of new and perfection of existent machines and their working organs for branches shallow in the gardens of intensive type with high density fruit orchard of landing. The area - machines and tools of mechanization of farming industry.
