Insufficient study of the characteristics of the material of harvested feed from herbs complicates the transition to more rational methods of work and restrains the creation of fundamentally new machines and technologies, which allows for reasonable to design equipment, choose the most effective ways of influence of working bodies on the material and ensure high quality of operations. The study of the physical and mechanical properties of agricultural materials is a prerequisite for the proper organization of the process and the design of machines.
Technological operations performed by feeding machines are aimed at changing the structure of these materials. In the process of processing, the hay is brought to a state that corresponds to agro -demands.
The type of working body and its parameters are determined by many factors: the necessary productivity, physical condition and nature of the material, quality and accuracy of processing, the efficiency of the machine and the level of its energy consumption.
The modern harvesting of legumes is aimed at improving the productivity of machines for their production, improving quality and feed value, introducing new methods of influence of working bodies on the material of the workpiece. Thus, the mathematical modeling of the work of the working bodies of feed harvesting machines should be based on the study of the physical and mechanical and technological characteristics of harvested feed mass with minimal nutrient loss and vitamins. Theoretical analysis of the processes of harvesting from herbs confirms the possibility of establishing estimated dependencies between productivity, energy costs and structural parameters of the working bodies of the machines, if the properties of the material are known.
Further development of prospective technologies and technical means in the field of feed harvesting requires a generalization of available theoretical and calculated research. This creates the basis for the emergence of new mechanization tools that can provide high productivity at minimal cost of material and energy resources per unit of quality feed.
The work analyzes the theoretical and calculated data of the functioning of the working bodies of machines in the process of influence on plant material during the harvesting of herbs. The calculations of parameters are related to the physical and mechanical properties of raw materials and agrotechnical requirements for the performance of operations.
