FIELD: mechanical engineering, cleaning machine of different kinds, in particular, snow removers and continuous - action combines, mainly with mechanical transmission. SUBSTANCE: the method consists in measurement of the machine operating parameters, comparison of them with the interval preset values and variation of the machine travelling speed in compliance with the results of comparison; the values of speed of the machine tool and the value of pull resistance to motion are measured as the working parameter for each machine speed. Interval values of pull resistances to motion are preset for each machine speed. The interval of pull resistances is selected, including the current value of pull resistance, and the coincidence of the current number of speed with the number corresponding to the selected interval is found. Rotational speed of the tool is controlled in case the pull resistance belongs to the preset interval, and correspondence of the current value of pull resistance to the interval of pull values is determined. Possibility of operation of the cleaning machine in optimum conditions, depending on the value of pull resistance to motion, makes it possible to enhance the machine efficiency and optimize the engine load, enhance the service life of the tool and machine proper. EFFECT: optimized cleaning process due to automatic variation of machine full and automatic variation of rotational speed of the tool, depending on the pull resistance to machine motion. 1 dwg |
