Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of accessory type agricultural film removing harrow, belong to agricultural implement technical field. BACKGROUND

[0002] When cultivating crops such as hot pepper in artificial greenhouse, it is necessary to remove the agricultural film at the place where the crops will be planted before planting. The agricultural film is a very thin plastic film, which is easy to be torn. When laying, it is laid in a whole piece (strip). When removing, it is necessary to ensure that there is no residue in the soil. If small teeth are used to remove, it will cause serious entanglement (because it is a whole piece). Conversely, if large teeth are used to remove, it will cause serious fragmentation (because it is easy to be torn). Therefore, in current practice, it is often necessary to use large teeth to clean first, then use smaller harrow to clean again, and finally use small teeth to clean again. The labor cost is very high, and the operation efficiency is too low.

[0003] There are mechanical devices in the prior art to solve the above problems, but such mechanical devices are often large in size and extremely high in cost. For small-scale farmers or planting experimenters, it is more economical to hire more helpers than to use such mechanical devices. Therefore, such mechanical devices cannot be applied to small-scale planting in practice. SUMMARY

[0004] To solve the above technical problems, the utility model provides an accessory type agricultural film removing harrow. Based on the setting of multiple types of teeth and the detachable structure of accessories, different types of teeth can be replaced according to different needs, the advantages of large teeth and small teeth can be effectively integrated, the labor cost can be greatly reduced, and the operation efficiency of removing agricultural film in small-scale planting can be greatly improved.
