Cotton harvesters for one-time cotton-picking

Abstract

The paper provides the study and substantiation of the parameters of semi-hitched spindle cotton harvesters during one-time cotton-picking. A calculation scheme for the spindle interaction with an open cotton boll in the "cylinder-deformable ball"form was proposed. A mathematical model to change the distance between oppositely located spindle drums in the working chamber and a method to calculate the indentation of the boll contact on the spindle of a vertical-spindle picking apparatus were obtained. The model made it possible to calculate the rational technological parameters of the device and machine. Kinematic functioning parameters of vertical-and horizontal-spindle picking devices were specified, taking into account their installation on a semi-hitched cotton harvester. The obtained data were used to create machines for a one-time cotton-picking.
