[0002] In the peanut planting process, mulching film covering technology is widely used, which can effectively maintain soil moisture, improve soil temperature and inhibit weed growth, thus creating a good environment for peanut growth. However, after mulching film covering, how to accurately and efficiently open holes in the film for peanut seeding becomes a key link.

Some simple mechanical hole opening devices, although they improve efficiency to some extent, often have unreasonable structure design problems. For example, common punching devices cannot flexibly adapt to the diverse row spacing required by different peanut varieties, and in the hole opening process, the mulching film is easily damaged due to the large impact force on the mulching film, affecting the heat preservation, water retention and other effects of the mulching film, and increasing the planting cost.
