Design and Experiment of Transport and Conveying Parts of the Pot Plate Seedling Classifier
摘要
Abstract
In the operation of pot plate classifier,the use of external gripper to pick up pot plate seedlings could effective-ly avoid the crushing of the matrix block,but the existing pot plate seedling transfer and transport parts were not suitable for the external gripper,which was easy to cause the matrix block of the seedling carrier to roll over and damage the seed-ling body,resulting in the failure of transport and of normal classification.Therefore,a bidirectional transport component of the transfer cup was proposed based on the pot plate classifier,so as to satisfy the external gripper to smoothly put and remove the carrier matrix block.The transfer cup was the core of the bidirectional transfer component.In order to ensure the fit with the external gripper,the stress analysis of the seedling carrier matrix block during the transfer process was car-ried out.Taking the relative gap between the inner diameter of the transfer cup and the outer diameter of the matrix block,the minimum height of the transfer cup wall and the pushing speed of the cylinder as the influencing factors,and the trans-fer success rate as the objective function,the transfer operation test of the bidirectional transfer parts of the transfer cup was carried out.The test results showed that when the relative gap between the inner diameter of the transfer cup and the outer diameter of the matrix block was 1.5 mm,the minimum height of the transfer cup wall was 30 mm,and the pushing speed of the cylinder was 0.3 m/s,the operation efficiency of the bidirectional transfer parts of the transfer cup could reach 3,600 rods/h,and the transfer success rate could reach 90%,which could meet the requirements of the classifier transfer operation.The research results could provide a technical reference for the research and development of the cavity disc seedling classifier.关键词
