Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an automatic mulching machine for transplanting tobacco seedlings in hilly areas. Background Technology

[0002] In the tobacco planting industry, although integrated transplanting and mulching machines have achieved the transplanting and mulching of tobacco seedlings, the low survival rate of seedlings remains a prominent issue in mountainous and hilly terrain. Taking Chinese invention patent CN111972097B as an example, this patent discloses a mulching and transplanting machine with multiple functions including mulching, automatic seedling separation, and transplanting, achieving automatic trenching, mulching, and planting, aiming to improve transplanting efficiency and reduce labor intensity. However, in practical applications, due to the uneven thickness of soft soil in mountainous and hilly terrain, when the "fixed transplanting cylinder" is inserted into the ground, if it encounters shallow soft soil, it cannot plant the seedlings to the predetermined depth, thus affecting the survival rate of the seedlings.

[0003] Meanwhile, the technique of transplanting flue-cured tobacco seedlings under plastic film has been rapidly adopted in tobacco-growing areas due to its advantages in increasing soil temperature, drought resistance and moisture retention, improving soil physical and chemical properties, shortening seedling recovery time, cultivating a well-developed root system, and resisting diseases and pests. This technique particularly emphasizes covering the seedlings under the film to promote better growth and reduce pests. However, traditional film-covering machines are inconvenient when changing the film, reducing film-covering efficiency. Therefore, there is an urgent need for an automatic film-covering machine for transplanting flue-cured tobacco seedlings under plastic film that can quickly change large rolls of film.

[0004] In conclusion, given the low survival rate of tobacco seedlings in mountainous and hilly terrain, and the inconvenience of changing film in traditional mulching machines, it is crucial to develop an automatic mulching machine for tobacco seedling transplanting that is suitable for mountainous and hilly terrain, can improve seedling survival rates, and facilitates quick replacement of large rolls of film. This will be key to promoting advancements in tobacco cultivation technology and increasing the economic benefits of tobacco production. Utility Model Content
