| 摘 要： | 排种器作为播种机关键部件,其工作性能与可靠性直接影响播种机整体作业质量。机械式排种器具有结构简单、价格低廉、维修方便等优点,勺轮式排种器作为机械式排种器的一种,在硬度较大、较规则种子播种作业中得到广泛应用。为此,应用Solid Works软件设计了一种勺轮式排种器,应用离散元软件对排种器排种大豆种子进行了计算机数值模拟,得到了排种器工作性能较好的工作参数。由离散元软件计算机数值模拟结果得到:勺轮组合转速为10~13 r/min,排种器种子室内种子数量在1 800~2 100粒时,排种器整体工作性能较好;且适当的振动可提高本设计的排种器的工作性能。该研究为勺轮式排种器的设计与优化提供了一种方法。

| Abstract: | Seed metering device as a key component of the seeding machine, its working performance and reliability directly affect the overall quality of the seeding machine.Mechanical sowing machine has the advantages of simple structure, low cost, convenient maintenance.The wheel metering device as a mechanical metering device of a widely used seeding with regular shape and hardness seeds.In this paper,the Solidworks software is used to design a spoon wheel type seed metering device, and the discrete element method is used to simulate the seed sowing seeds of the seed metering device, and the working conditions of the seed metering device are obtained.Simulation results are obtained by the discrete element software: the whole working performance of the seed metering device was better when the wheel rotation speed was 10~13 r/min;the number of seeds in the seed room was 1800~2100.And appropriate vibration can improve the performance of the designed device.This paper provides a method for the design and optimization of the spoon wheel type seed metering device. |
