Simulation Analysis of the Sugarcane Leaves Cutting Process of the Electric Returning Machine

Abstract

In order to improve the sugarcane leaves cutting effect of electric sugarcane leaves returning machine, the sugarcane cutting process is modelled and simulated by ANSYS/LSDYNA software. It shown that in the double-support cutting mode, the cutter roller ensures the multi-layer sugarcane leaves were cut at the rotate speed of 800 rpm. During the cutting process of sugarcane leaves, the stress is mainly concentrated at the incision, and the sugarcane leaves on the side of the blade are subjected to greater stress. The smaller the distance between the rotary blade and the fixed blade of the same combination, the easier the sugarcane leaves are cut off. In the cutting test of sugarcane leaves, the cutting rate was 91.47%, which echoed the simulation results, indicating that modelling and simulation have reference value.

Sugarcane leaf return and mixing significantly reduce slope runoff and soil loss

“…Thus, we designed four slopes (5°, 10°, 15° and 20°) in this study. Moreover, sugarcane leaves and stalks were produced at a ratio of 1:5 (Lin et al, 2020). Field investigations have shown that the sugarcane yield ranges from 1 to 7 t/ha, which suggests that the sugarcane leaf yield ranges from 2.5–17.5 t/ha.…”

“…Several studies have indicated that years of soil and water conservation measures in lateritic red soil areas have achieved far fewer benefits than losses caused by soil erosion (Liu & Han, 2021). Drawing on the experience in other regions, returning sugarcane leaves to the field may be the best approach to improve the soil quality in lateritic red soil areas and address the existing atmospheric pollution caused by large‐scale incineration (Lin et al, 2020). The effect of returning sugarcane leaves to the field on the soil quality, disease incidence, pests and weeds in agriculture, sugarcane output and greenhouse gas emissions in soil has been extensively studied by many scholars (Hilton et al, 2017; Li et al, 2019; Lin et al, 2020).…”

These studies have provided extensive scientific guidance and a theoretical basis for research on the effect of sugarcane leaf return on soil erosion and have promoted related research worldwide.…”
