摘要：

为提高甘蓝收获效率，研制适合我国甘蓝种植模式的收获机械，以测定的“秋甜”甘蓝品种的基础物理特性参数为基础，设计一种可实现甘蓝拔取输送的单行悬挂式收获装置。应用SolidWorks软件对装置三维建模并导入Adams软件进行动力学仿真，得到收获过程甘蓝与螺旋凸棱的接触力和甘蓝摆动垂直度的仿真结果，进行正交组合分析表明：装置的最佳工作参数为机具前进速度0.4m/s、螺旋杆转速300r/min、螺旋凸棱外径70mm、限位间距166mm时，收获甘蓝的垂直度最高，通过田间试验表明该装置收获过程甘蓝的采净率和破损率分别为97.6%、8.24%，收获性能符合预期设计，为研究收获装置样机提供理论基础。

Abstract:

In order to improve the harvesting efficiency of cabbage, a harvesting machine suitable for China's cabbage planting mode was developed. Based on the measured basic physical parameters of the “Autumn Sweet” cabbage variety, a single-row hanging harvesting device that could realize cabbage picking and conveying was designed. SolidWorks software was used to build the three-dimensional model of the device and Adams software was imported for dynamic simulation. The simulation results of the contact force between cabbage and screw convex ridge and the verticality of cabbage swing during harvesting were obtained. The orthogonal combination analysis showed that the best working parameters of the device were as follows: the forward speed of the machine was 0.4 m/s, the screw speed was 300 r/min, the outer diameter of screw convex ridge was 70 mm, and the spacing for limiting displacement was 166 mm, the verticality of harvesting cabbage was the highest, the field test results showed that the harvesting rate and damage rate of cabbage in the harvesting process of this device were 97.6% and 8.24% respectively, and the harvesting performance meets the expected design, which provides a theoretical basis for the study of the prototype of the harvesting device.
