Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and particularly relates to a residual film raking device. Background Art

[0002] After harvesting crops, residual plastic films remain in the fields and need to be collected and processed to prevent the residual films from mixing into the crops during the next harvest. For example, when harvesting corn stalks or alfalfa, the mixture of residual films may cause livestock to accidentally ingest them, which has an adverse impact on the health of livestock.

[0003] Currently, existing plastic film raking machines are usually used to clean the residual films in the fields. During the operation of the plastic film raking machine, the bottom of the rake teeth needs to extend into the ground. The rake teeth of the plastic film raking machine will be deformed due to long-term stress, and the gap between adjacent rake teeth will change, resulting in incomplete raking of the films. A large amount of plastic films will remain in the fields and need to be inspected manually, which has a high labor intensity. Content of the Utility Model
