The conditions of effective utilization of flax harvesting combine units

Abstract

The paper presents the tsiklogramma of employing flax harvesting combine units. It also investigates the distribution of the unit shift duration, its idle time and the coefficients of the shift worktime utilization. The statistical dependence of the productivity on its effective employment and the dependence of the coefficient of the shift worktime employment on the shift duration have been estimated. The paper analyzes the length of run and the duration of dinner break of crews of flax harvesting units. It also evaluates the effects of the above factors on the productivity of combine units. The correlation of the unlit productivity depending on the length of runs and the duration of dinner breaks was 0,397 and 0,418 respectively. The graphical dependence of the unit productivity alteration on the factors under study is suggested. The paper investigates the working day duration for flax harvesting unit teams and their productivity under the actual conditions of machine use. It studies the statistical distribution of the investigated signs. The correlation between the unit productivity and the duration of the operator working day has been determined. The quantitative dependance of the unit productivity change on the working day duration has been revealed. The working hours and dinner time duration are considered as the organizational and technological factors which determine the efficiency of using flax combine harvesters. The author covers such indices of the efficiency of using harvesters the coefficient of using time before their chanqe, the hour productivity and the percentage of fulfilling the rate of output. Under the changes of the working hours within the studied limits the given coefficient and the rate of output also change along the domeshaped curve. The harvester rate of output increases according to the logistic dependence along with the increase in the dinner time duration.
