Abstract
Nowadays, the available haulm removing machines and mechanisms do not fully meet the agronomic requirements for the process of harvesting roots. In this paper, the need to design new haulm removers and improve the available ones is substantiated. The results of experimental and theoretical studies require a more detailed description and analysis on the basis of the obtained data during field tests of an advanced haulm removing machine. The technological process of the module operation for harvesting the tops of root crops is primarily regulated; it depends to a large extent on the technological feeding of the plant components cut off with knives of rotary haulm removers. Therefore, the results of experimental studies of the auger conveyor performance are given in this paper. Based on the obtained results, the efficiency of the developed analytical and applied model of the feed process of cut vegetable components to the auger conveyor of the haulm removing module is proved. The discrepancy in the experimental values of the auger conveyor performance (obtained in accordance with the regression equation) and the theoretical values of its performance (obtained at the analytical level according to the mathematical model) ranges from 5 to 10%. The rational parameters of the auger conveyor of the haulm removing module are defined: auger diameter – 0,35 m; auger rotational frequency – 350 rpm.
