| Abstract: | In order to ensure the balling rate of the 4 MKJ-plastic film recovery combined operation machine,solve the problem that the film stacking come loose easily,and increase the degree of automation,a 4 MKJ-plastic film recovery combined-operation machine open-type hydraulic system was designed.Considering the work requirements and field conditions,this paper made the oil cylinder action plan,designed and drew the open type hydraulic system schematic diagram.The actuator includes four groups of symmetric installed in the machine on both sides of the cylinder,by tying device to adjust oil cylinder telescopic flexible compensation coreless membrane bundle of expansion in quantity.The hydraulic pump and cylinder were calculated and selected.The working pressure of the hydraulic pump is 13.5 MPa and the flow rate is 7.2 L/min.Modeling and simulation analysis of the open hydraulic system was carried out by AMESim software,and the piston displacement curve of the cylinder and the input signal curve of the reversing valve of the open hydraulic system was obtained.Finally,the bundling test was carried out in the field,and the bundling situation of the 4 MKJ combined machine for plastic film recovery with an open hydraulic system was statistically analyzed,and the bundling rate was selected as the evaluation index.The field bundling test shows that the bundling rate can reach 95.7%,which meets the application requirements.The open hydraulic system of the 4 MKJ plastic film recovery joint operation machine can run stably and ensure the baling rate without core film. |
