Design and Experiment of Spade Tooth Film Lifting Device for Residual Film Recycling Machine
摘要
Abstract
Aiming at the problems of low life span of the pick-up device of the residual film recycling machine and film leakage in the process of operation,a spade tooth film lifting device was designed to improve the residual film recovery rate and operational efficiency.The structure and arrangement of the teeth were designed,and the mechanical analysis and calculation of the teeth were carried out to determine the factors affecting the film pick-up device.Using EDEM software to carry out discrete element simulation on the edge film teeth,the operating model of edge film teeth-soil was established,the angle of the edge film teeth into the soil was selected,the shape of the edge film teeth shovel blade was taken as the test factors,and the combined force on the edge film teeth and the amount of abrasion were taken as the evaluation indexes,and two-factor and three-level simulation test was adopted.The test results showed that when the angle of the edge film teeth into the soil was 35 °,the shape of the edge film teeth shovel blade was SP2,the operational performance was better,the combined force was 228.83 N,the wear amount was 2.81 mm,the better combination of the analysis of the soil deflection situation,that the soil surface was hump-shaped can effectively lift the soil,through the ANSYS structural static module coupled with the EDEM to get the maximum stress of the edge film teeth.The maximum stress was 48.513 MPa and the maximum deformation was 0.416 mm,simulation results showed that the structural design and operation of the tines met the design requirements.The field test results showed that the average film lifting rate of the shovel tooth film lifting device was 94.2％,and the results can provide a reference for the design of film lifting device of the residual film recycling machine.关键词
