<i>Key technologies on crop dividers of sugarcane harvester: a review</i>

HighlightsThis article focuses on crop dividers of sugarcane harvesters.Four crop dividers were briefly reviewed.The research status of crop dividers was introduced.The potential new technologies and development directions of spiral crop dividers were presented.Abstract. The crop divider is an important mechanism of a sugarcane harvester, which affects the efficiency and quality of sugarcane mechanical harvesting. This article mainly summarized the key technologies of crop dividers. Firstly, four crop dividers (spiral crop divider, finger-chain crop divider, combined crop divider, and lever crop divider) were briefly reviewed. The advantages and disadvantages of different crop dividers were then summarized. The research status of crop dividers was introduced with theoretical analysis, simulation studies, and field experiments. Finally, the scientific researches and commercial machines were compared for a comprehensive review. Additionally, the potential new technologies and development directions of spiral crop dividers were presented to improve the performance and adaptability of sugarcane harvesters. This article is expected to provide a reference for the design of crop dividers. Keywords: Crop divider, Mechanical harvesting, Sugarcane, Sugarcane harvester.

With the increasing trend of mechanized harvesting of green sugarcane the trash residue needs to be used. Leaving large amounts of trash remaining on the field can sometimes lead to problems such as delay of sprouting of tillers, increased levels of leafhopper infestation and difficulty of tillage operation. Windrowing of trash after harvesting can minimize these problems. To eliminate the operation of trash windrowing and to facilitate the trash decomposition, the Sugarcane Technology Center, CTC (Centro de Tecnologia Canavieira), Brazil developed a trash shredder system for a primary extractor of John Deere chopper sugarcane harvester. Using rotating knives all vegetable material passing through the primary extractor is chopped, thereby reducing the particle size. After some adjustments, preliminary tests were carried out to prove the efficiency of chopping and sugarcane cleaning. The machine produces a much smaller trash particle size than conventional harvesters. The system shows promise in shredding trash either for use at the mill or for dispersion on the field.
