摘　　要：为将山地果园和其他园林场所修剪废弃的直径小于30mm的树枝,粉碎成长度小于30mm、粒径小于5mm的木屑,设计了一种厚锤片单通道喂料辊喂料非重复式粉碎的可移动小型树枝粉碎机。根据锤片式粉碎原理,设计时改进喂料装置、转子总成和锤片的尺寸结构与工作方式。检测试验结果表明：改进设计的粉碎机最佳主轴转速范围为2 050~2 200r/min,在2 100r/min主轴转速时生产率可达0.851m3/h,单位能耗低至3.162kW·h/m3;机器参数水平理想,粉碎效果良好。In order to crush waste branches with the diameter not exceeding 30 mm trimmed from mountain orchards and other garden places,into sawdust with a length not exceeding 30 mm and particle size not exceeding 5mm,a small moveable thick hammer branch grinder was designed and improved,where branches may be fed by the feeding roll through a single-channel,and crushed in a non-repetitive way.On the basis of hammer crushing principle,the size,structure and working methods of the feeding devices,the rotor assembly and hammer were redesigned and improved,which achieved the design goal of the grinder.The crushing experiments to determine the spindle speed showed that the optimum spindle speed range for the grinder is 2 050-2 200r/min,and the crush confirmatory experiments showed that when the spindle speed is 2 100r/min,the productivity can reach 0.851m3/h,and the unit energy consumption will be as low as 3.162kW·h/m3.The parameters are ideal,and the crushing effect is good.
