Type Analysis of a Multiloop Coulisse Mechanism of a Cotton Harvester

Abstract

Vertical spindle cotton harvester. Planetary gear. Cotton harvester apparatus. The paper is devoted to the type analysis of the multiloop coulisse mechanism of the spindle drum of a cotton harvester. Provide a description of the design of the multiloop coulisse mechanism of the cotton harvester; identify the cause of breakdowns of individual parts of the specified mechanism; carry out the type analysis of the structure of the studied mechanism; present the optimal type of the studied mechanism. Research methods are based on the type analysis of the kinematic chain of the multiloop coulisse mechanism by increasing the freedom of kinematic pairs. A complete description is made and an analysis of the multiloop coulisse mechanism is performed. The main causes of breakdowns of individual parts of the new design of the spindle drum are clarified. The results of studies on the elimination of redundant constraints in the kinematic chain of the mechanism are presented. The kinematic chain is reduced from a statically indefinable system to a statically definable one. The optimal type of the kinematic chain of the multiloop coulisse mechanism has been developed. Research results will be useful for the wide practical application of spindle drums with multiloop coulisse mechanisms in the construction of vertical spindle cotton harvesters.
