HighlightsThis article focuses on the sugarcane top chopper.The influence of three factors on the experimental indexes was studied.The optimal parameters combination of working performance was obtained.Abstract. In the process of sugarcane harvesting, sugarcane tops are cut off by the chopper and directly thrown into the field. A small percentage of sugarcane tops are picked and collected to feed livestock. Therefore, it is meaningful to develop an effective sugarcane top chopper which is used to harvest sugarcane tops before harvesting sugarcane stalk harvesting. In this study, a sugarcane top chopping platform was fabricated to investigate critical parameters such as chopping speed (CS), top feeding speed (FS), and cutting drum gap (DG) on the machine performance. In evaluating the sugarcane top chopper, three single factor experiment and one orthogonal experiment were carried out. The single factor test was used to examine the effect of CS, FS and DG on the chopping performance of the machine. According to orthogonal test, the comprehensive influence order was determined: cutting drum gap > chopping speed > top feeding speed. The optimal parameters combination for good working performance of the machine was obtained: chopping speed was 750 rpm, top feeding speed was 1.2 m·s-1, and cutting drum gap was 20 mm. The relationships between the chopping performance and the three critical factors were examined and analyzed to provide theoretical basis for the development of a sugarcane top chopper.

Abstract: In order to analyze the relation between surface roughness of Pyinkado plates and sanding parameters, an orthogonal experiment and a single factor experiment were performed. The results show that the mesh of the sandpaper has remarkable influence on surface roughness of Pyinkado plates, but the feeding speed and sanding thickness don’t; when the mesh of the sandpaper is 150, the feeding speed is 6 m/min and sanding thickness is 0..4 mm during the first sanding and the mesh of the sandpaper is 240, the feeding speed is 9m/min and sanding thickness is 0.15mm during the second sanding, the smallest roughness (Ra) was obtained as 2.81μm. Considering production efficiency, changing feeding speed into 9 m/min in the theory optimization scheme, engineering optimization scheme was obtained, and the wood surface roughness (Ra) is 2.91μm.

HighlightsThis study focused on the base cutting energy consumption for sugarcane stools instead of single stalks, thus being more consistent with actual field harvesting.The energy consumption increased with increasing rotational speed (RS) and stool diameter (SD), while it decreased with increasing tilt angle (TA) and feed rate (FR).Each pair of levels of each factor was compared using Duncan’s multiple range test. Three factors (RS, SD, and FR) had significant effects on energy consumption at 95% confidence level, while one factor (TA) had no significant effect.The order of influence and the optimal combination of the four factors to minimize the energy consumed during base cutting were determined.Abstract. Previous studies on contra-rotating basecutter designs based on supported cutting have mainly focused on the base cutting energy consumption for single sugarcane stalks instead of sugarcane stools. However, in the actual base cutting process, a basecutter typically cuts multiple sugarcane stalks (in one sugarcane stool) simultaneously. Therefore, this study investigated how the rotational speed (RS) and tilt angle (TA) of the cutting discs, the sugarcane stool diameter (SD), and the feed rate (FR) affected the energy consumed when cutting cane stools using a contra-rotating cutting platform. Four single-factor experiments and an orthogonal experiment were performed using a Taguchi orthogonal experimental design, and each group was replicated five times. The results of the single-factor experiments showed that the energy consumption was proportional to RS and SD, while it was negatively correlated with TA and FR. The significance of the difference between each pair of levels of each factor was investigated using Duncan’s multiple range test. According to the results of the orthogonal experiment, RS, SD, and FR had significant influences on the base cutting energy consumption at the 95% confidence level; however, TA had no significant influence. The order of influence of the four factors was SD > FR > RS > TA (18.45 > 18.39 > 12.91 > 9.06), and the optimal factor-level combination for minimizing the cutting energy was RS2, TA4, SD1, and FR3 (200 rpm disc RS, 20° disc TA, 60 mm SD, and 1.0 m s-1 FR). An understanding of the relationships between energy consumption and its influencing factors can serve as a valuable reference for researchers seeking to optimize the design of contra-rotating basecutters, which could lead to increased energy efficiency and a reduction in energy consumption during sugarcane harvesting.
