摘要

摘要: 为解决现阶段食用菌生产基地人工翻堆方式存在作业环境差、劳动强度大、工作效率低以及物料混合不均等问题，提出一种双辊式翻堆装置的翻堆机。该翻堆装置利用双螺旋方式对抛刀进行分布设计，根据分层切削原理，利用小半径抛刀作业来实现较大翻堆深度；通过构建双辊翻堆的离散元仿真模型，利用EDEM软件对翻堆装置的工程进程和不同工况下颗粒流动、碰撞和抛撒情况进行分析，通过仿真分析和Central Composite Design试验分析确定双辊轴间距525.17 mm,轴线夹角35.25°的最优组合。最后进行实地试验验证离散元模拟翻堆机翻堆作业的可行性并对翻堆机作业性能进行测试，试验结果表明：作业后料堆混合系数为0.714,作业功耗为1.828 kW,表明该翻堆机具有良好的破碎与混合效果。

Abstract: In order to solve the problems of poor working environment, high labor intensity, low work efficiency and uneven mixing of materials in the manual turning method of edible fungi production base at the present stage, a kind of turning machine with double-roller turning device was proposed. The turning device used a double-helix method to design the distribution of the throwing knives according to the principle of layered cutting, the small-radius throwing knives was used to achieve a large turning depth. By building a discrete element simulation model for double-roller turning piles, the EDEM software was used. The engineering process of the turning device and the particle flow, collision and scattering of particles under different working conditions were analyzed. Through simulation analysis and Central Composite Design test analysis, the optimal combination determined that the double-roller axis spacing was 525.17 mm and the axis angle was 35.25°. Finally, the field test was carried out to verify the feasibility of the discrete element simulation of the turning operation of the turning machine and the test results showed that the mixing coefficient of the pile after operation was 0.714, and the operating power consumption was 1.828 kW, which shows that the compost turner has good crushing and mixing effects.
