Determining the angle of inclination of the cutting strip of the feeder of a rotary snow blower

Abstract

The article contains the results of theoretical studies of one of the parameters of the geometric image of the feeder cutter of a rotary snow blower — the angle of inclination of the cutting strip of the vertical feeder, relative to the radius of the vertical cutter. The work contains not only recommendations on rational values of the angle of inclination of the feeder cutting strip, but also presents some specific values of the width of the feeder cutting strip, at which the working process of a rotary snow blower can be considered most effective. A calculation scheme for determining the angle of inclination of a vertical cutter has been compiled. The article presents the types of interaction of a vertical cutting strip with a snow massif. Key types of interaction are presented schematically. The dependences of the angle of inclination of the tangent to the cutting path as a function of the angle of rotation relative to the radius of the cutter were obtained. Conclusions are drawn about the dependence of the angle of inclination of the cutting strip on the angle of rotation of the cutter. Several periodically repeating sections during the operation of a rotary snow blower have been identified and presented, which indicates the presence of patterns in this process. The functional dependences of the geometric dimensions of the cutting strip of a rotary snow blower on the angle of inclination of the vertical cutting strip and the angle of rotation of the vertical cutter are determined.
