摘要: 为发挥洞庭湖区自然资源优势，带动沅江经济、生态发展，填补目前国内外芦苇笋采收机研究空白，设计了一款集中掰断式芦苇笋采收机。通过实地调研收集采摘芦苇笋数据，基于柔性双同步带夹持掰断芦苇笋原理，设计了9组同步带机构和2组回转式刀具切尾装置，并根据芦苇笋不同立地角度将其等效简化为悬臂梁力学模型，运用牛顿运动定律和刚体转动定律，列出切尾装置理论功率、掰断和夹持输送芦苇笋理论功率参数表达式。试验结果表明：机具消耗功率约为理论功率的97.9%,液压马达型号GM5-6功率匹配合理；芦苇笋采摘率和损伤率与采摘执行机构同步轮转速和机构倾角相关，当同步轮转速为3000r/min、机构倾角为12°时，采摘率为94.6%,损伤率为6.9%,采收效果最好。Abstract: In order to play the natural resources advantage of Dongting Lake District, promote the economic and ecological development of the ruanjiang, and fill the current domestic and foreign reed shooting machine research on the collection. This article designs a concentrated anti-broken reed shooting machine. Through the ground research, the use of reed shoots, based on the flexible dual synchronous belt clamping the principle of reeds, 9 groups of synchronous belt mechanisms and 2 sets of reincarnated tool cutting devices, and according to the different angles of reed shoots, etc. Simplified simplification of the cantilever beam mechanical model, using Newton’s law and rigid rotation law, list the theoretical power of the tail tailing device, the disconnection and clamping delivery of the theoretical power parameters expressions. The test results show that the power consumption is approximately 97.9%, and the hydraulic motor model GM5-6 power matching is reason. Reed shoot rate and damage ratio are associated with picking executive synchronous wheel speed and institutional inclination, and finally, this harvesting machine is obtained in: The synchronous wheel speed is 3000 R/min, and the maneuveral inclination is 12 °, the picking rate is 94.6%, the damage ratio is 6.9%, the harvesting effect is best.
