Abstract :収穫期が労働のピークとなるため,南西諸島地域のサトウキピ農業は,機械収穫体系の導入が進められ,農地の集積や農作業の受委託による効率的で安定した生産法人等による機械化経営を目指している.効率的な機械作業を進めるためには,農作業計画の最適化を行う必要があるしかし作業計画は圃場毎の作業履歴を記録し,データを分析しながら効率的に考えられるべきである.本研究では,運送業界で広く活用されている車載情報システムを小型サトウキピ収穫機に搭載し農作業記録装置として利用し収穫機の作業実態を詳細に調査した.その結果,エンジン回転数を用いることで,収穫機の作業内容を正確に分析できた. GPSの走行軌跡より収穫機の刈り取り面積を8%以下の誤差で計測することが可能でトあった.映像記録型ドライブレコーダーを用いることで刈り取り量の推計が可能となった.今回のサトウキピ収穫機の一日の実作業率は0.4程度で一般的な農作業機械の値とされる0.6~ 0.85と比較すると小さく,また圃場での有効作業効率は35%程度と低いこれは刈り取りが後退法で行われているためと考えられる.
Because demand for labor is at its peak during the sugarcane harvesting season, mechanical harvesting is beneficial on the small islands of far southwestern Japan. The efficiency and stability of farm management there can be improved by grouping small, scattered farms and the use of mechanical harvesting contractors. For efficient machinery operation, it is necessary to optimize the work plan. Agricultural work can be planned by recording machinery operations in the fields and analyzing the data. To do this, we mounted a digital tachograph system, as widely used in the transportation industry, on a small sugar cane harvester to record the work of the harvester. Using engine revolution data, it was possible to record the working conditions of the harvester precisely. Using GPS data, it was possible to measure the area harvested with an error of :S8%. The harvest volume was estimated from images obtained with a digital camera. The working efficiency of this harvester over the course of a day proved to be low, at approximately 0.4, compared with typical values of 0.6-0.85 for common agricultural machinery; the field working efficiency was as low as 0.35. The likely explanation for the low efficiency is the use of a one-way harvest in back and forth motions.
