中文摘要 | 本研究發展之夾持脫聯系統採用皮帶夾持式,其脫莢齒為橡膠材質,應用於本省鮮株脫莢之收穫時,其收穫性能比一般投入式脫莢法為優。根據脫莢筒速度與脫莢性能之關係試驗結果,脫莢筒轉速於450rpm至500rpm之脫莢效果最佳。由脫莢夾持位置與脫莢性能之關係試驗結果分析,脫莢夾持位置在17cm脫莢效果最佳。夾送速度與脫莢性能之關係試驗結果顯示,夾送帶速度在90rpm至110rpm時,其脫莢效果較適合。研製完成之夾持式落花聯合收穫機主要機構包括疏株、鬆土裝置、拔株夾送裝置、夾持脫莢裝置、選別與輸出裝袋裝置,履帶行走裝置及動力系統等。本機使用25馬力柴油引擎,每次採收一畦兩行,拔株、夾送、脫莢、選別、裝袋等作業一次完成。根據田間收穫試驗結果,平均拽株率99.2%,地下殘留率1.8%,地飛損失率2.0%,未脫莢率2.5%,帶子房柄率9.9%,破裂莢率3.2%,夾雜物率6.2%,理論作業能率每公頃8-10小時。 |
英文摘要 | Due to the high cost in harvesting of peanut by hand labors, this study was attempted to develop a feasible harvester for peanut farmers. Based on the plant type and the physical characteristics of the Plants, a clamping-type of peanut combine was developed at Tainan DAIS in 1988. The machine is equipped with a 25-HP of diesel engine, and a working system for pulling-up, lifting, threshing, clearing and packing. Results of the testings indicated that the appropriate position of clamping is set up at 17 cm from the clamping belt to the threshing cylinder center, the best speed of the threshing cylinder is maintained at 45-500 rpm and the clamping belt at 90-110rpm. The combine harvester can be used in the cultivation of peanut on beds. The appropriate width of the bed is one-meter with two rows of peanut. The results also indicated that 99.2% of the plants were removed, 1.8% of the pods were lost in the ground and 2% were dropped on the ground, 2.5% of the pods were unthreshed, 9.9% of the harvested pods were with peg, 3.2% of the pods were damaged by the machine. There were 6.2% of plant debris and/or soil were found in the harvested material. The harvesting efficiency of the machine is 8-10 hrs/ha. The design and technology has been transferred to a private agricultural machine factory for commercial production. |
