摘　　要：针对大坡度山地果园运输难、耗能高的问题,设计1种依靠货物自身重力运输的山地果园无动力运输机。运输机主要由自适应阻尼装置、遥控急刹装置、遥控控制系统、增速装置、冷却风扇、运输车等组成,能实现一端运输车在货物重力作用下沿20°~50°坡地或直线水泥槽内安全匀速下行,另一端带着空运输车上行。该运输机仅需1个12V电瓶提供遥控制动时所需动力,通过遥控器遥控急刹装置,能实现运输机在任意点的启停。试验表明,在长时间运行时,维持制动毂温度小于50℃状态下,运输机能稳定以最大速度0.7 m/s匀速运行,最大载荷为1t。该运输机工作可靠、运行平稳、操作简单、无需运输动力,适合偏远大坡度山地果物的运输,节能环保。An unpowered orchard transporter relied on its own gravity was developed to solve the difficulties of fruits transportation in large slope mountain. The design was mainly composed of adaptive gravity damping device, fast braking apparatus, remote-control system, gearbox, cooling fun, carriages, etc. The system can achieve one side of the carriages with fruits driving down in the cement trough or slope at the degrees of 20 to 50 relying on the gravity of fruits in a moderate speed and the other side of the empty carriages driving up the hill. The transporter only requires a storage battery（12 V） to provide the power when the control system makes the fast brake apparatus to work. The transporter can realize reliable barking at any point along the cement trough. Results showed that the transporter kept the temperature of the bark drum between 20 ℃ and 50 ℃ when the carriages was driving at the speed of 0.7 m/s with the maximum load of 1 000 kg. The transporter operated simply, worked reliably and run smoothly with no extra power, which is suitable for the remote large slope mountainous area with energy conservation and environment protection.
