摘　　要：为提高残膜回收机工作效率、减少卸膜次数、保证机具作业行程,部分机具配备了较大的集膜箱与残膜压实装置;但膜箱较大,存在卸膜困难费时和卸膜不彻底的情况,且残膜在经过压实之后容易卡住,更不易卸出,严重影响残膜回收机的作业效率。为此,针对当前带有较大集膜箱的残膜回收机卸膜繁琐且不彻底的问题,设计了一种剪叉式的卸膜装置。同时,介绍了总体结构以及工作原理,采用虚位移原理得出了油缸最大推力的计算公式;对外侧剪叉臂进行受力分析,推导出剪叉臂铰接处的最大铰点力;进行加工试制,并进行实地试验。通过对集膜箱内不同质量的残膜进行卸膜,验证该装置卸膜彻底,基本无残留,可满足工作要求。In order to improve the working efficiency of the plastic film recycling machine,reduce the number of film unloading,and ensure the working stroke of the machine,some machines and tools are equipped with large film collecting box and plastic film compaction device.However,due to the large membrane box,it will be difficult to unload the film and waste time.Moreover,the plastic film is easy to be stuck after compaction,and it is not easy to unload,which seriously affects the operation efficiency of the plastic film film recycling machine.For this reason,in order to solve the problem of tedious and incomplete film unloading in the plastic film recovery machine with large film collecting box,a shearing fork type film unloading device is designed.The overall structure and working principle are introduced.The calculation formula of the maximum thrust of the oil cylinder is obtained by using the virtual displacement principle.The force analysis of the outer shear fork arm is carried out,and the maximum hinge point force at the hinge point of the shear fork arm is deduced.Finally,the device was processed and trial produced,and field test was carried out.Through the film unloading of different quality plastic film in the film collecting box,it was verified that the device was completely unloaded,basically no residue,and met the working requirements.
