Tooth-type recovery device for potato residue film

The invention belongs to the field of agricultural machinery, and particularly relates to a tooth-type recovery device for potato residue film. The device comprises a trolley box (9), wheels (10), a break shovel (19), a film picking device, a residue film delivering device and a film collecting box (15). The device is characterized in that a tooth-type structure is firstly used and is combined with a potato harvester, the structure is high in practicability, simple and convenient to manufacture and install, better operability is achieved during the actual production, and the operation is convenient. A special film removing device is not needed, the film collecting box with larger capacity is arranged, after a field experiment, film picking and film removing are good, and the damage to potatoes is low. 本发明属于农业机械领域，特别涉及种带齿式马铃薯残膜回收装置。该装置包括车箱(9)、车轮(10)、松土铲(19)、拾膜装置、残膜输送装置和集膜箱(15)。本发明的最大创新点在于首次使用带齿结构与马铃薯收获机相结合，此结构适用性强、结构简单、便于制作和安装，在实际生产中具有良好的可操作性，操作方便。而且不需使用专门的脱膜机构，并有较大容量的集膜箱。经实地实验，拾膜、脱膜理想，伤薯率较低。
