Problems solved by technology
[0004] The main reasons for the large internal tensile stress of the film laid out by the existing film laying machine are: ①The film is always in a stretched state, and the stress cannot be eliminated; ②Because the distance between the film pulling roller and the film feeding roller is relatively long, And there are many bonding points on the mulch roll, and the same piece of mulch will be repeatedly pulled

Embodiment
[0019] Embodiment: the biodegradable film automatic film laying machine film discharge device in this scheme, such as figure 1 , comprising a film feeding roller 2, a film pulling roller 4, a film peeling mechanism 3 and an air extraction device, and the film feeding roller 2 is equal in diameter to the pulling grinding roller 4. The film mechanism 3 is located above the film feeding roller 2 . like figure 2 , The film-removing structure includes a limiting plate 8, a suction rod 5 and an eccentric wheel 10, and the limiting plate 8 is processed with a through hole for clearance fit with the suction rod 5. like image 3 , the top of the suction rod 5 is integrally formed with an arc section corresponding to the large-diameter arc section of the eccentric wheel 10, and seals such as O-rings and sealing rings are installed between the suction rod 5 and the mulch. An airway 6 is integrally formed in the limiting plate 8, and the airway 6 leads to a through hole, and the air e...

The invention belongs to the field of a device for laying covering, specifically discloses a film discharging device of an automatic bio-degradable film laying machine. The film discharging device comprises a film feeding roller and a film drawing roller, and further comprises a film uncovering mechanism located above the film feeding roller; the film uncovering mechanism comprises a limiting plate, an absorbing rod and an eccentric wheel, a through hole matched with the absorbing rod is formed in the limiting plate, an air way communicated with the through hole is formed in the limiting plate; the absorbing rod is disposed in the through hole, a suction cavity is arranged in the absorbing rod, an air hole corresponding to the through hole is formed in the wall of the suction cavity; the eccentric wheel is arranged above the absorbing rod and can touch the absorbing rod, a flange is arranged on the absorbing rod, a spring is fixed on one end of the flange, the other end of the spring is fixed on the limiting plate. The tensile stress in a mulching film during a film discharging process is reduced by the intermittent function of the absorbing rod to the mulching film.
Description
technical field [0001] The invention belongs to the field of devices for laying coverings. Background technique [0002] At present, plastic film mulching is one of the key technologies widely used in the field of cultivation in my country. It achieves the effects of early maturity, increased yield and quality improvement of crops during the growth period by supplementing the accumulated ground temperature and improving soil moisture changes. The "white revolution" also produced serious "white pollution". Because polyethylene (PE) plastic film belongs to polymer compound, it is extremely difficult to degrade, and its degradation cycle reaches 200~300 years. Year after year, the use of broken and residual film accumulates in the soil layer year by year, polluting the soil environment, resulting in a decline in the quality of cultivated land, affecting crop yield and quality, and ultimately leading to unsustainable agricultural production. [0003] Therefore, in order to cont...
