          摘要:

          為克服現有山地果園軌道運輸機無法搬移、戶外施工難度大、批量生產困難和設備利用率低等問題,設計了一種山地果園拆裝單向牽引式雙軌運輸機,分析該機的總體結構及繩徑選擇、軌道最小傾角、軌道最長長度、軌道最小轉彎半徑和斷繩制動裝置的工作原理,并進行樣機運載試驗。計算與分析結果顯示: 運輸機鋼絲繩直徑為7.7 mm, 軌道最小傾角為5.7°, 軌道最長長度為170 m, 軌道最小水平轉彎半徑為7 m, 最小垂直轉彎半徑為2 m。運載試驗結果顯示:運輸機上行平均速度為0.51 m/s,下行平均速度為0.54 m/s,平均能耗為1.235 kW·h,使用有效度為100%。這表明該運輸機可適用于山地果園運送肥料和果品等,亦可搭載噴霧機或果枝修剪機械等進行作業。

          Abstract:

          In order to overcome the transition,field operation, and standardized batch production difficulties of the existing track cargo vehicle in mountainous orchard, as well as to raise the utilization rate, the mountain orchard detachable unidirectional traction double track cargo vehicle was developed. This paper introduced the whole machine structure, the wire rope diameter selection,the minimum track inclination,the maximum track distance,the minimum track turning radius and the working principle of the rope brake device. Load experiments were carried out to test the cargo′s synthetic track function. It is indicated by calculation that the wire rope diameter should be 7.7 mm,the minimum track inclination was 5.7°, the maximum track distance was 170 m, the minimum track horizontal turning radius was 7 m, and the minimum track vertical turning radius was 2 m. Load experiment results indicated that the cargo vehicle′s uplink average speed was 0.51 m/s, the downlink average speed was 0.54 m/s, the average energy consumption was 1.235 kW·h and the effective use degree was 100%. This cargo vehicle was suitable for fruit, pesticide, chemical fertilizer and other cargo transportation in the mountain orchard. Meanwhile, it can be applied to carry the spraying machine, the shave machine and other agricultural machines.
