Abstract

Aiming at the problem that there are few studies on the turnover device in the current peanut laying operation equipment and lack of simulation parameters, this study measured the characteristic parameters of upright peanut plants and tested the feasibility of conveying the turnover device to flip the vine. By studying the mechanical properties of peanut plants, the suitable clamping height range of plants was determined. By studying the size, mass parameters and distribution of peanut plants, the possibility of plant flipping and falling was analyzed, and the main structure and working principle of the conveying flipping device were determined.Based on the RECURDYN-EDEM coupling, the joint simulation of the conveying and overturning device was carried out to complete the dynamic analysis of the plant conveying and overturning process, and the simulation parameters were further optimized. The test results show that the device can achieve 95.1 % plant turnover completion and improve the quality of field drying, which can meet the requirements of peanut laying and harvesting operation. It can provide a theoretical basis for the design of two-stage peanut harvesting device in the future.

针对目前花生铺放作业机具中翻转装置相关研究较少且缺乏仿真参数的问题，本研究对直立型花生植株特性参数进行测定，试验输送翻转装置翻转秧蔓的可行性。通过研究花生植株力学特性，确定植株适宜夹持高度范围；通过研究花生植株的尺寸、质量参数及其分布规律，分析植株翻转掉落的可能性，确定输送翻转装置的主要结构与工作原理。基于RECURDYN-EDEM耦合开展输送翻转装置联合仿真，完成植株输送以及翻转过程的动态分析，进一步优化了模拟参数。试验结果表明，该装置可实现植株翻转完成度95.1%，田间晾晒质量提高，能够满足花生铺放收获作业要求，可为今后两段式花生收获作业装置的设计提供理论依据。
