Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a straw cutting device for a mulch film collecting machine. BACKGROUND

[0002] Agricultural mulch film has excellent heat and moisture retention, and in the process of agricultural production, a large amount of mulch film is used to improve crop yield. In order to ensure the sealing performance, the two sides of the mulch film need to be buried in the soil. After the crops are mature, the mulch film needs to be removed for secondary use of the land. When the mulch film is removed, the part buried in the soil needs to be dug up to avoid the residual mulch film remaining in the soil. Only in this way can the mulch film be completely exposed to the surface to avoid tearing the mulch film during collection. However, after the crops are harvested, the stems (such as corn stalks, peppers, eggplants, etc.) remain in the soil, and the straw needs to be cut before the mulch film can be collected. At present, most of the cutting is done manually, which is very inefficient. The existing technology also has a method of cutting the straw by machine and then collecting the mulch film by the mulch film collecting machine. However, this method requires different personnel to operate, which is extremely wasteful of labor costs.
