Design and experiment of silage baling and wrapping machine with electric driving

Aiming at the problems of silage baling and film wrapping link separation，large supporting power，an silage baling and wrapping film machine with electric drive was designed. By analyzing the working principle of the machine and the operation process of the core components，the main parameters such as the power of feeding and baling device，the linear speed of conveyor belt，the opening angle of the baling chamber，and the time required for 2~3 layers of film wrapping were determined，the reliability simulation of the frame at full load and the performance test of the whole machine were carried out. The results show that the frame maximum stress was 116.4 MPa and the maximum deformation was 0.71 mm under full load condition，which meet the mechanical properties of the material. The bundling rate was 97.8%，the regular bundling rate was up to 100%，the bale density was 148.2~162.5 kg/m3，and the straw bale resistance rate was 84.0%. The whole machine runs smoothly and reliably with small vibration，the low straw bale resistance rate may be caused by the straw being too uniform and short，and the twine was not complete，which can be optimized in the later crushing treatment and twine mechanism. © 2024 Editorial Board of Jilin University.
