为克服现有山地果园轨道运输机无法搬移、户外施工难度大、批量生产困难和设备利用率低等问题，设计了一种山地果园拆装单向牵引式双轨运输机，分析该机的总体结构及绳径选择、轨道最小倾角、轨道最长长度、轨道最小转弯半径和断绳制动装置的工作原理，并进行样机运载试验。计算与分析结果显示: 运输机钢丝绳直径为7.7 mm， 轨道最小倾角为5.7°， 轨道最长长度为170 m， 轨道最小水平转弯半径为7 m， 最小垂直转弯半径为2 m。运载试验结果显示：运输机上行平均速度为0.51 m/s，下行平均速度为0.54 m/s，平均能耗为1.235 kW·h，使用有效度为100%。这表明该运输机可适用于山地果园运送肥料和果品等，亦可搭载喷雾机或果枝修剪机械等进行作业。
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.
