摘要
为改善因喂苗机构与栽植器时空位置匹配不佳造成的栽植效率低下的问题,在2ZB-2型移栽机的基础上研制了带有链排式喂苗机构的试验台,分析喂苗机构与栽植器时空匹配关系,确定影响投苗率的因素,并使用ADAMS软件进行单因素仿真试验得出各因素的水平范围,通过高速摄影进行验证。使用Box-Benhnken中心组合试验方法设计三因素三水平正交试验,进行响应曲面分析,以投苗率作为响应值得出:在理想条件下,秧苗水平线速度为0.202m/s(移栽机前进速度2.2km/h)、喂苗机构垂直高度120mm、水平距离10mm时,实现了喂苗机构与栽植器的最优时空匹配关系,人工劳动强度适宜,喂苗机构的投苗率达到100%,且基质损坏率较低。
In order to improve the low planting efficiency caused by the poor matching of the seedling mechanism and the planter space-time position,the test bench with the chain-row feeding mechanism was designed and manufactured on the basis of the 2ZB-2 transplanter,and the seedling was analyzed.The time-space matching relationship between the mechanism and the planter was used to determine the factors affecting the seedling rate.The ADAMS software was used to perform the single-factor simulation test to obtain the horizontal range of each factor,which was verified by high-speed photography.Using the Box-Benhnken center combination test method to design a three-factor three-level orthogonal test,the response surface analysis was carried out,and the seedling rate was used as the response.Under the ideal conditions,the horizontal speed of the seedlings was 0.202 m/s(the transplanter forward speed was 2.2.Km/h),the vertical height of the feeding mechanism is 120mm,and the horizontal distance is 10mm.The optimal space-time matching relationship between the feeding mechanism and the planter is realized.The artificial labor intensity is suitable,and the seedling rate of the feeding mechanism reaches 100%and the matrix damage rate Lower.
