Description

Technical Field

[0001] The utility model relates to the technical field of double film laying machines, in particular to a stretchable and adjustable double film laying machine. Background Art

[0002] The use of the double-film laying machine enables the upper narrow film to seal the seed holes in the lower layer, thereby increasing temperature and retaining moisture. In this way, the cotton seedlings sown on the film can emerge naturally, while fully utilizing the advantages of natural resources such as light and heat under the film. Especially in early-sown cotton fields, when the natural temperature and soil moisture are at the critical period for cotton emergence, the cotton sown by the double-film laying machine emerges early and evenly, injecting new vitality into the high-quality and high-yield of cotton.

[0003] At present, the film laying structure of most double film laying machines generally lacks the telescopic adjustment function, which results in that during the film laying operation, the positions of the two films often remain relatively fixed and cannot be flexibly adjusted. This design brings many inconveniences to the film laying work and reduces work efficiency.

[0004] Therefore, in view of the fact that the film laying structure of the above-mentioned double film laying machine lacks the telescopic adjustment function, resulting in reduced work efficiency, a stretchable and adjustable double film laying machine can be designed. Through the telescopic adjustment and the threaded transmission structure, the film laying structure of the double film laying machine can be conveniently adjusted to meet different film laying needs.
