Berezovyy M. The substantiation of technological and design parameters of the machine executive devices for harvesting haulm of sugar beets

Object - executive devices of haulm gathering machine for cutting, transporting and loading of haulm and process of their interaction with haulm. Purpose - increasing of harvesting efficiency of haulm from heads of root crops of sugar beets on the basis of a choice of rational constructive and kinematic parameters of executive devices for haulm cutting, transporting and loading. Methods - theoretical investigations are made with applying of methods of postulates of higher mathematics, theory of mechanisms and machines. In their fundamentals methods of compiling of the differential equations of movement are supposed. The worked out equations are solved by numerical methods by means of the computer. Experimental researches are done by conventional and private techniques, with use of mathematical method of scheduling of experiment, with use of means tensometric. Data processing of experimental researches was carried out with statistical methods by means of software packages of the data analysis. Novelty -1) analytical dependence of average force of rotary haulm cutting apparatus from mechanical-technological parameters (diameter of bundle, mass of bundle, elastic resistance to inflexion, critical velocity without support blade cutting of freely standing bundles of haulm) has been received. The power necessary for cutting of haulm mass has been defined; 2) productivity of rotary haulm cutting apparatus on the basis of analytical expression for definition of square of haulm cut in a vertical plane has been defined; 3) rational kinematic and design data of a loading device on the basis of a solution on computer systems of the differential equations received by working out of mathematical model of movement process of haulm particle on its executive devices have been defined; 4) technique of experimental definition of damages of sugar beets haulm has been developed by transporting and loading executive devices; 5) new associations of damages of haulm on kinematic conditions and design data of executive devices ofhaulm gathering machine have been established; 6) power parameters of transporting and loading of executive devices and as a whole three-row haulm gathering machine which executes technological process of continuous without support blade cutting of sugar beets have been validated. Results of investigation. On the basis of results of researches the constructions of haulm gathering machine and their executive devices which are protected by 4th patents have been offered. Results of researches and received recommendations can be used at projection, working out and modernising of new constructions of haulm gathering machine. Branch - Machines and means of agricultural production mechanization.
