摘　　要：鉴于当前棉秆分散、收储季节性强的特点,现有小型棉秆收集设备已满足不了棉秆工业化利用的要求,因而研究开发了适应我国棉秆收集现状的棉秆联合收获机。其中,切碎装置为整机的关键部件。对棉秆联合收获机切碎装置的类型和结构进行研究,设计了适合棉秆切碎的平板滚筒式切碎器,并对切碎装置进行了动力学分析,确定其理论切碎长度为27mm,切碎滚筒直径为600mm,滚筒长度为720mm,转速为1 165r/min。试验结果表明:该切碎装置具有切碎性能好、切碎质量高以及工作可靠等优点。Due to dispersion of cotton-stalk,togather with harversting and storaging seasons limited,the small cotton-stalk harvesting equipments on the market can't meet the need of industrial extensive use.of cotton-stalk.A new type cotton-stalk combine harvester was studied,and cutting device was the key components.Cutter mechanism was kinetic analyzed,it was determined that the cutting length was 27mm in theory,the diameter of the cutting rotor was 600mm,the length of the cutter was 720mm and the speed of rotation was 1165r/min.The test shows that the cutting device performance with cutted,cutted high quality,reliable work etc.
