Five-rod type planting mechanism applicable to electric drive transplanter in dry land

Abstract

The invention aims at the multi-objective parameter optimization problem of coordinated optimization of controlled characteristic parameters and agronomic requirement parameters of a double-crank five-connecting rod type planting mechanism of an electric drive transplanter in dry land, a closed vector equation is used to describe the motion characteristics of the mechanism, actual agronomic parameter requirements and other requirements during operation of a transplanter are transformed into constraint conditions, after weight distribution is performed through a matrix method, the controlled characteristic is obtained through combination and is used as an objective function, a genetic algorithm is used to optimize and determine the structural parameters of the mechanism, so that the controlled double-crank five-connecting rod planting mechanism is designed.

Description

technical field [0001] The planting mechanism manufactured according to the mechanism design parameters optimized by the optimization method of the present invention is under the premise of fulfilling the agronomic requirements, the output torque of the drive motor and the speed performance of the planting mechanism during work meet the working requirements and are always maintained in a relatively stable state. And realize the minimization of energy consumption and the maximization of working efficiency. It provides a reference for the mechanism design of the controlled double-crank five-link planting mechanism in the hybrid motor-driven transplanting machine in the future. Background technique [0002] Most of the currently used transplanting machines use internal combustion engines as direct or indirect power. Since the operation process consumes a lot of fuel resources and causes a certain degree of pollution to the environment, it has been gradually replaced by electric...
