摘　　要：针对目前温室内以内燃机为动力的微耕机在作业时普遍存在的污染严重、人跟机走、操作不便、作业成本高等问题,研制了一种微型遥控电动拖拉机,并进行了整机性能试验。试验结果表明,该机转向机动性能良好,最小转向半径为418mm,可用于温室相对狭窄的作业环境;行驶直线性较好,偏驶率为0.86%,采用了与单铧翻转犁配合使用的平行四边形机构和深松铲,有效地解决了偏牵引问题;作业效率为720m2/h,连续作业时间可达2.5h;作业能耗成本约为14.4元/hm2,分别比蓝天1DN-4微耕机、合盛1Z-105微耕机降低89.2%、79.3%～88.7%,具有较显著的经济效益,表明该机适用于温室和大棚特殊环境的作业要求。To solve the problems of serious pollutions, going along with the machine, inconvenient operations and high operating costs etc, a tiny remotely controlled electric tractor was designed. Its overall performances were tested in plowing condition for greenhouse. The results showed that the tractor exhibited good turning maneuver performance with the minimum turning radius of 418 mm, which can be used in greenhouses under the relatively narrow operating environment. Traveling rectilinear was preferable with the yawing rate of 0.86%. Parallelogram mechanism and shovel in conjunction with single ploughshare turnover plow effectively solved the problem of partial traction. The operating efficiency was 720 m 2 /h, continuous operation time was 2.5 h. The operating energy costs were approximately 14.4 yuan/hm 2 , which were 89.2% and 79.3% to 88.7% lower than those of Lantian 1DN-4 micro-farming machine and Hesheng 1Z-105 micro-cultivator, respectively. The results suggested that this machine had more significant economic benefits and was suitable for the operational requirements of the special environment of greenhouses and sheds.
