Description

增程器、混合动力插秧机和混合动力插秧机的工作方法Working method of range extender, hybrid rice transplanter and hybrid rice transplanter 技术领域Technical field
本发明涉及到农业机械领域，尤其涉及到增程器、混合动力插秧机和混合动力插秧机的工作方法。The invention relates to the field of agricultural machinery, in particular to the working method of a range extender, a hybrid rice transplanter and a hybrid rice transplanter.
背景技术Background technique
插秧机是一种常见的农业机械，在其辅助下可以快速地完成对于农田的插秧作业。Rice transplanter is a common agricultural machine, which can quickly complete rice transplanting operations on farmland with its assistance.
目前的插秧机使用的动力源为内燃机，内燃机式的插秧机存在着较多的问题，一方面是内燃机式插秧机利用燃油工作，由于对于燃油的利用率有限导致排出的气体中存在着较多的污染物质，另一方面是内燃机式插秧机本身在工作时多处于低效能区域，整体的工作效率较低。Current rice transplanters use internal combustion engines as the power source. Internal combustion rice transplanters have many problems. On the one hand, internal combustion rice transplanters use fuel oil. Due to the limited utilization of fuel, there are more exhaust gases. On the other hand, the internal combustion engine-type rice transplanter itself is mostly in the low-efficiency area when working, and the overall work efficiency is low.
清洁能源和绿色农业是当前农业的一大发展趋势。进一步地，当所述插秧机的动力源是内燃机时，大多采用HST(整体式液压传动装置Hydrostatic Transmission)变速机构，HST变速机构低速扭矩小。当所述插秧机的本身的重量较大或者是载重量较大时，所述插秧机容易陷入到农田中。Clean energy and green agriculture are a major development trend of current agriculture. Further, when the power source of the rice transplanter is an internal combustion engine, the HST (Hydrostatic Transmission) transmission mechanism is mostly adopted, and the low-speed torque of the HST transmission mechanism is small. When the weight of the rice transplanter is large or the load capacity is large, the rice transplanter is easy to sink into the farmland.
HST采用液压传动时，传动效率较低，并且使用一段时间后，磨损损耗较大，造成整个所述插秧机的后期维护成本较高。When the HST adopts hydraulic transmission, the transmission efficiency is low, and after a period of use, the wear loss is relatively large, resulting in higher maintenance costs for the entire rice transplanter.
