Description
Technical field
The invention belongs to the device field of laying covering.
Background technology
At present, covering with ground sheeting is one of wide variety of key technology of China's cultivation field, it pass through addedly accumulated temperature, change
The morning that the effects such as kind soil moisture content change reach crop growth period sends out the effect of precocity, volume increase and quality improving, but mulch film covers
Cover and also create serious " white pollution " while producing " White Revolution ".Due to polyethylene（PE) plastic sheeting belongs to high
, it is extremely difficult to degraded, its degradation cycle was up to 200 300 years for molecular compound.Accumulated year by year using broken residual film year after year and plough in soil
Layer, contaminated soil environment, lead to farmland quality to decline, affect crop yield and quality, ultimately result in can not holding of agricultural production
Continuous.
Therefore, in order to continue to ensure soil temperature raising produced by plastic foil covering, soil moisture conservation effect, Biodegradable mulch substitutes
Existing common PE film has become the development trend in future.At present, Biodegradable mulch is all to be laid by film-laying machine, film-laying machine
Correlation grind and make internal disorder or usurp quite ripe, but the structure of membrane device is roughly the same, is all setting membrane roller in front of lay-on roll, passes through
Mulch film is pulled down from lay-on roll by membrane roller.However, from the point of view of Biodegradable mulch test situation, existing film-laying machine is used for spreading
If Biodegradable films affect greatly so that Biodegradable films tear too early on the degradation speed of Biodegradable films, thus can not reach
To expected coverage effect.Film strips are left behind from film roll mainly by pulling force and are laid on field by existing film-laying machine, and mould volume is in cutting
When, making mould roll up both sides mulch film and between layers bonding occurs, so pulling down mulch film from mould volume, running into the bonding on mulch film
During point, mulch film will be subject to larger pulling force, makes to produce tension inside mulch film.
Inside the film that existing film-laying machine spreads out, tension essentially consists in the reason larger：1. mulch film is constantly in stretching shape
State, stress cannot eliminate；2. again because the distance between membrane roller and lay-on roll farther out, and have a lot of bondings on film roll
Point, same section of mulch film can repeat under tension.Lead to mulch film inner membrance pulling force excessive, the mulch film completed also just remains one in field
Fixed tension, makes mulch film be constantly in tension state, thus, along with Plastic-film disintegration, mulch film intensity decreases are rapid, mulch film pole
Easily tear, also demonstrate this viewpoint from degradation film cracking mode.Especially for the Radix Bupleuri this cycle needing overlay film
Very short plant, needs biomembrane degradation speed very fast, and the thickness of Biodegradable films therefore used is less than 0.005mm.Therefore, grind
Send the little equipment of the pulling force that Biodegradable mulch is subject in plastic film mulch and become current Radix Bupleuri and plant mulch film and lay the urgent of operation
Demand.

Mulch film rides in membrane roller, allows and there is one section of reserved mulch film between lay-on roll and membrane roller.Now, such as directly initiate membrane
Roller, reserved mulch film can be consumed by membrane roller, and on lay-on roll, mulch film only could after reserved mulch film is depleted
It is pulled down into.And mulch film can be opened while lay-on roll rotates from lay-on roll by the setting of film stripping machine structure, so that sending
It is always maintained at reserved mulch film between deflector roll and membrane roller, and then eliminate the pulling force to mulch film for the membrane roller, drawing suffered by mulch film
Power only has film stripping machine structure to apply.When eccentric in film stripping machine structure up moves, friction member is contacted with mulch film, and with mulch film
Move upwards, make mulch film depart from film roll.Hereafter eccentric moves down, and friction member moves down because of deadweight, and separates with mulch film, completes one
The individual cycle take off film action.Now there is gap between mulch film and film roll, with the rotation of lay-on roll, mulch film without
Draw, also can depart from from film roll, and then keep there is reserved mulch film section always between lay-on roll and membrane roller.
The having the beneficial effects that of this base case：Limiting plate limits the scope of the motion of connecting rod, and spacing hole allows even
Extension bar slides wherein, and limits the movement locus of connecting rod.When eccentric completes to take off film action, on the one hand by eccentric
Overcome the power of each adhesive spots, make the pulling force that the mulch film section between lay-on roll and membrane roller is not repeated, every section of mulch film is solely subjected to
Pulling force.On the other hand, while eccentric overcomes bonding force, mulch film is opened from film roll, turning with lay-on roll
Dynamic, the mulch film being lifted can naturally drop, and is that reserved mulch film section creates condition between lay-on roll and membrane roller.Formed pre-
After staying mulch film section, membrane roller only need to overcome the gravity of reserved mulch film section just mulch film can be pulled to next station, and mulch film itself
Frivolous, that is, need the pulling force that reserved mulch film is applied negligible.Furthermore the intermittence effect to mulch film for the friction member, gives
The time of stress relieving in mulch film.The present invention reduces the tension within mulch film in terms of three above.
Further, described connecting rod is provided with two friction members, and the distance between two friction members are equal with the width of mulch film.
Because mainly in mulch film both sides, friction member directly acts on the place close to adhesive spots to the adhesive spots between ground film layer, makes ground
The area reduction of film under tension.In addition do not cover in crop surface more than mulch film both sides, but in crop both sides, even if so depositing
Only has minor impact in the tension also growth to crop.
Further, also include fraction wheel drive device, described friction member is friction pulley, friction pulley and fraction wheel drive device
Connect.Because when speed being moved on friction member less than lay-on roll rotation linear velocity, during lay-on roll moves on friction member
Rotating, when friction member is in extreme higher position, between friction member and lay-on roll, there is mulch film packing phenomenon, affect film stripping machine structure
The action in next cycle.When friction pulley is contacted with mulch film, mulch film can be driven to membrane roller side shifting, friction member can be made and send
