项目摘要

For the development of the mechanization system in sugar cane cultivation which is one of the main crop in Nansei-shotou islands, Kagoshima prefecture and Okinawa prefecture, automatic planter of sugar cane seedling with two germs was developed and researched and the following results were obtained.1.Development and performance of cutting device for sugar cane seedling with two germs : To obtain seedling in 20cm length from detrashing plant, a stopper was attached to high speed cutter. For the plant of bending ratio under 3, two to three detrashing plant could be cut continuously. The cut seedlings were 20cm<plus-minus>2cm and 1500 pieces per hour (2.2h/10a) were cut vertically in section and almost all seeding were in good condition without fine spl2.Development and performance of draw out device for sugar cane seedling : Two parallel polyurethane rollers with 30cm in length and 20cm in diameter were used for draw out device. At the rolling speed of 10.5 to 11.5cm/s on outer surface, roller clearance of 16mm and the vibration ratio of 6c/s, the draw out device showed best performance for the planting velocity of 0.4 to 0.6 m/s. Any damage was seen and the direction of the seedlings were good.3.Development and performance of planting device : Under the draw out device, planting device was developed which transport each seedling with channel attached conveyer and seedlings were dropped on the seeding bed. This device showed a good leveling performance at vibrating rate of 6 to 15 c/s and vibrating amplitude of 12mm and the draw out ratio of 104 to 106% seemed to be best at any operating velocity.4.Planting accuracy and capacity : The final planting ratio was 98% with planting depth 18.0cm, planting pitch 3.0cm and calculated field capacity 22.5a/h and seedling were ina good posture. With these results, the developed sugar cane planter seemed to have enough capability in actual usage on the field. Further resaech about the durability of the draw out roll is expected.
为了发展南西诸岛、鹿儿岛县和冲绳县主要农作物之一的甘蔗种植机械化系统,开发和研究了甘蔗二芽苗自动播种机,并取得了以下成果。 1.甘蔗二芽苗切割装置的开发和性能:为了从除杂植物中获得长度为20cm的幼苗,使用塞子 连接到高速切割机。对于弯曲比小于3的植物,可连续切割2~3株除草植物。切苗直径为20cm±2cm,每小时垂直切苗1500粒(2.2h/10a),几乎所有的秧苗状态良好,没有细粒。 甘蔗秧苗抽苗装置的研制和性能:抽苗装置采用两个平行的长30cm、直径20cm的聚氨酯滚轮。在外表面滚动速度为10.5~11.5cm/s、辊间隙为16mm、振动比为6c/s时,拔出装置在播种速度为0.4~0.6m/s时表现出最佳性能。没有任何损坏,苗的方向良好。3.播种装置的开发和性能:在抽出装置下开发了播种装置,用通道附有的输送机输送每棵秧苗,并将秧苗落在苗床上。该装置在振动速率6~15c/s、振动幅度12mm下表现出良好的整平性能,在任何运行速度下,拔出比为104~106%,似乎都是最好的。 4、播种精度和容量:最终播种率为98%,播种深度18.0cm,播种间距3.0cm,计算田间容量22.5a/h,出苗状况良好。姿势。从这些结果来看,所开发的甘蔗播种机在田间的实际使用中似乎具有足够的能力。期望对抽出辊的耐用性进行进一步研究。
