Description

Technical Field

[0001] The utility model relates to the technical field of residual film removing machines, in particular to a machine for removing residual film from farmland soil. Background Art

[0002] When the land is covered with film for planting, a certain amount of film will still remain inside the land after the crops are harvested. The film wraps the soil and is not easy to decompose, which affects the next planting. Before planting, the film inside the land can be burned by a remover, which can effectively improve the quality of removing the film. However, most of the removers in the existing technology are traction-type, and the movement of the frame needs to be supported by support wheels. When the land environment is relatively humid, it is easy for a large amount of soil to stick to the outside of the support wheel, and the speed of the support wheel is low, causing the soil to be thrown away by centrifugal force. It is easy for the soil to support the frame, making it impossible for the rotary roller and other structures to contact the ground, resulting in the remover being unable to effectively remove the film. Therefore, there is a need to improve the existing technology. Utility Model Content
