Design and Experiment of Longitudinal Automatic Seedling Feeding Device for Vegetable Transplanting Machine
摘要
Abstract
Aiming at the problem that the longitudinal plug tray feeding device of vegetable transplanter had low adaptability to different plug tray sizes and the flexible plug tray was easy to bulge during the plug tray feeding process,which led to inaccurate plug tray feeding,a longitudinal automatic seedling feeding device for vegetable transplanters was designed,comprising a longitudinal automatic pushing mechanism and a pressing mechanism.Firstly,the shape and size of the plug tray were analyzed,and an ideal D-shaped longitudinal pusher trajectory was proposed to adapt to the shape and size of most plug trays.Based on the transmission principles and working methods of a single-planetary gear train and a pantograph,a longitudinal automatic pushing mechanism capable of proportionally scaling trajectories was designed.Secondly,utilizing kinematic models of four-bar mechanism and genetic optimization algorithms,a reciprocating pressing mechanism complementing the pushing mechanism was optimized.Finally,longitudinal automatic feeding tests were conducted using two plug tray specifications.For Type I(32 mm feed distance),operational accuracy exceeded 93.43%with a maximum deviation of 2.1 mm.For Type II(36.5 mm feed distance),accuracy surpassed 93.15%with a maximum deviation of 2.5 mm.The tests confirmed the feasibility of achieving stable longitudinal feeding for multi-specification plug trays and effectively resolve plug tray convexity issues,demonstrating good versatility and applicability,thus providing a new solution for longitudinal seedling feeding across multiple plug tray specifications.关键词
