地膜具有增温、保墒、除草、防虫等作用,因此得到了广泛推广应用并且极大地促进了我国农业经济的发展。可是,地膜大批残留在泥土中很难降解,给农业生产和生态环境形成很大破坏。针对残膜回收难这一实际问题,通过对现有残膜回收机的收膜部件和自动卸膜装置的对比分析,提出实现自动卸膜的方法并设计出旋转弹齿式残膜回收机自动卸膜装置。 Film has a warming, moisture, weeding, pest control and other effects, it has been widely promoted and greatly promoted the development of China’s agricultural economy. However, a large number of residual plastic film in the soil is difficult to degrade, to agricultural production and the formation of a great ecological damage. In view of the practical problem that the residual film recovery is difficult, a method to realize the automatic film unloading is proposed by comparing the film collecting components of the existing residual film recovery machine and the automatic film unloading device, and a rotary elastic tooth film remover is designed to automatically Unloading device.
