摘　　要：为实现开沟施肥覆土一体化联合作业,在微型手扶开沟机基础上,设计了排肥装置和覆土装置,主要有排肥装置的肥料箱、重心配置、覆土板和仿形装置结构设计。实现了动力从行走轮传到排肥器、肥料箱重心稳定、排肥量可调、覆土板能在上下高度差约80 cm实现仿形功能。田间试验结果表明,设计配有排肥和覆土装置的开沟机工作时施肥量达到50 kg/h,覆土率达78.3%,覆土均匀度较好。The article is based on micro handed ditcher and it designs fertilization devices and covering soil devices which mainly include the transmitting designment of distributing device,central assignment,covington soil and simulation forms in order to achieve the cooperation of ditching,fertilization and covering soil.It implements the power from the wheel to rows fertilizer,the stability of the centeral point of fertilizer box,the adjustment of fertilizer consumption,covering plate achieving simulation function under this condition which its altitude is around 80 cm.The experimental conclusion in field shows that the speed of fertilization is 50 kg/h,the rate of covering soil is by 78.3% and its degree of uniformity is good.
