环形土槽微耕机试验平台设计

Design of Micro-cultivator Testing Platform with Annular Soil Bin

针对传统的微耕机田间试验受多种因素影响,而室内直线土槽无法进行可靠性试验,设计了可连续作业的环形土槽微耕机试验平台。采用闭合式环形土槽及轨道,实现试验平台长时间循环作业。各功能台车分开布置,台车上、下部的六轮行走机构及可转动的侧轮支轴,实现了台车在轨道上平稳运行及顺畅转弯。微耕机试验平台融合了上、下位机的自动控制技术、多传感器技术、无线通讯技术、园林灌溉技术等,实现了田间工况的重复模拟,既可进行性能试验又可进行可靠性试验,并能够对土壤坚实度、土壤含水率、微耕机扶手振动及受力等10余项数据进行实时采集和处理。

Traditional micro-cultivator field tests were restricted by many factors,and reliable tests in liner soil bins indoors could not be conducted;however,a new type of micro-cultivator testing platform was developed which could be performed continuously.The lengthy cyclic operations of the test platform were realized by adopting annular soil bins and closed-ended tracks.Functional trolleys were arranged individually so that they could walk steadily and swivel on six-wheeled walking mechanisms in the upper and lower trolleys,as well as the rotatable side wheel shaft.The platform merged upper and lower computer automatic controls,multi-sensors technology,wireless communication,gardens irrigation technology etc.Field conditions were simulated repeatedly.Performance and reliability experiments could both be carried out.More than ten parameters such as soil firmness,soil moisture,oscillation and forces of micro-cultivator handling etc.were collected,displayed and analyzed conveniently by the micro-cultivator testing platform.
