Technical Field

[0001] The invention relates to the technical field of flue-cured tobacco cultivation, in particular to a film-laying device for a flue-cured tobacco cultivation ridge and a use method thereof. Background Art

[0002] Flue-cured tobacco, also known as fire-tube tobacco, originated in Virginia, USA. It has special morphological characteristics, so it is also called Virginia type. Flue-cured tobacco is the type of tobacco with the largest cultivated area in my country and the world. It is the main raw material of the cigarette industry. When raising seedlings of flue-cured tobacco, it is necessary to cover the ridge with a film, and a paving device will be used. Its main function is to keep warm and moisturize, inhibit weed growth, reduce water evaporation and promote the early growth of tobacco seedlings.

[0003] Traditional mulch film laying relies primarily on manual labor, which is not only labor-intensive and inefficient, but also prone to problems such as uneven film laying and loose soil covering, which affect the mulch film's coverage. Furthermore, flue-cured tobacco cultivation requires drilling holes in the film for seedling cultivation. Manual drilling is not only time-consuming and labor-intensive, but also difficult to maintain consistent hole spacing and depth, hindering the standardized cultivation of tobacco seedlings. Currently, there are some mulch film laying devices on the market, but most have simple structures and single functions, making it difficult to simultaneously meet the multiple operational requirements of film laying, pressing, covering, and drilling. Although some mechanized mulch film laying equipment has improved efficiency, it suffers from poor adaptability, complex operation, and high cost.

One end of the slide bar 27 is located outside the mounting box 21 and is fixed to the knife cylinder 26. The outside of the slide bar 27 is located between the lifting plate 24 and the bottom of the inner wall of the mounting box 21 and is sleeved with a second spring 28.

[0041] It should be noted that when the present invention is used, the film on the film laying roller 4 is unfolded, and the cooperation of the driving motor 14 and the reducer 15 can drive the moving wheel 16 forward, so that the device moves smoothly. As the device moves, the film automatically unfolds and covers the surface of the ridge body. The roller 9 at the front end of the device initially presses down the two ends of the film to position it so that the film fits the ridge body and avoids the film from deflecting.
