基于可变参数化设计的精量化播种机结构研究
Structure of Precision Seeder Based on Variable Parameterization Design
摘要
Abstract
With the continuous expansion of agricultural production scale,precision sowing has been rapidly applied in agricultural production due to its advantages such as high sowing accuracy and fast speed.However,due to the impact of the working environment such as farmland hardness and terrain,precision seeders are prone to getting stuck or blocked by foreign objects during operation.At the same time,the seeder cannot automatically adjust the sowing depth based on the depth of the farmland,which affects the sowing quality.This paper deeply analyzed the functional requirement of the pre-cision seeder,introduced the variable parametric design concept,and completed the 3D modeling of the precision seeder by analyzing the working principle and control parameters of the key componentd of the precision seeder.At the same time,it optimized the parametric design process,and completed the 3D model design of different parameters according to the parametric operation process.Finally,through field seeding operations,the results showed that the precision seeder based on variable parameterization had a reasonable structural design,stable operation,and the sowing depth met the re-quirements,achieving the expected design goals.关键词
