Description
Technical field
The invention belongs to lay the device field of covering.
Background technology
At present, covering with ground sheeting is one of wide variety of key technology of China's cultivation field, it by addedly accumulated temperature, change
The effects such as kind soil moisture content change reach the effect for the morning of crop growth period sending out precocious, volume increase and quality improving, but mulch film covers
Cover and also generate serious " white pollution " while " White Revolution " is produced.Due to polyethylene（PE) plastic sheeting belongs to high
Molecular compound, it is extremely difficult to degrade, its degradation cycle is up to 200 300 years.Accumulated year by year using broken residual film year after year and ploughed in soil
Layer, contaminated soil environment causes farmland quality to decline, and affects crop yield and quality, ultimately results in can not holding for agricultural production
It is continuous.
Therefore, in order to continue to ensure that plastic foil covers produced soil temperature raising, soil moisture conservation effect, Biodegradable mulch is substituted
Existing common PE film has become the development trend in future.At present, Biodegradable mulch is laid by film-laying machine, film-laying machine
Correlation grind and made internal disorder or usurp quite ripe, but general configuration is similar, is all for the same of plastic film mulch by assembled from different farm machineries
When complete other operation process.However, from the point of view of Biodegradable mulch test situation, existing plastic film mulch is deposited with following shortcoming.①
Because mulch film is constantly in extended state, stress cannot be eliminated so that the mulch film completed remains certain drawing in field should
Power, makes mulch film be constantly in tension state, thus, along with Plastic-film disintegration, mulch film intensity decreases are rapid, and mulch film easily tears,
This viewpoint is also demonstrated from degradation film cracking mode.2. because the distance between membrane roller and lay-on roll farther out, and ground
There are many adhesive spots in film roll, same section of mulch film can multiple under tension, cause mulch film to be easily torn.
The content of the invention
It is an object of the invention to provide a kind of Biodegradable films automatic film paving machine membrane device is solving during plastic film mulch, it is raw
The problem of Biodegradable films low intensity after the easy damaged and plastic film mulch of thing degradative membrane.
In order to achieve the above object, this programme provides a kind of Biodegradable films automatic film paving machine membrane device, including film feeding
Roller and membrane roller, also including rotary column, aspiration box, jet box, the first commutation cylinder, the second commutation cylinder, air pump and driving means, drive
Device is connected with rotary column, and the input of air pump is connected with aspiration box, and the outfan of air pump is connected with jet box；Jet box is provided with
Through hole, the side wall of jet box is provided with fumarole, and fumarole is provided with air jet pipe, and air jet pipe extends to lay-on roll by drawing grinding roller side；
Aspiration box is provided with through hole, and the side wall of aspiration box is provided with suction hole, and suction hole is provided with suction nozzle, and suction nozzle extends to lay-on roll
Top；Gear is provided with the top of the top of the first commutation cylinder and the second commutation cylinder, the first commutation cylinder is arranged on jet box, second
Commutation cylinder is arranged in aspiration box, and the outer wall of the first commutation cylinder is provided with the first opening corresponding with fumarole, the second commutation cylinder
Outer wall is provided with the second opening corresponding with suction hole, and rotary column is axially spaced to be provided with two sector gears corresponding with gear.
The principle of this base case is：Before startup, first manually mulch film is slowly opened, of short duration startup lay-on roll, then will
Mulch film is ridden in membrane roller, is allowed between lay-on roll and membrane roller and be there is one section of reserved mulch film.Now, membrane is such as directly initiated
Roller, reserved mulch film can be consumed by membrane roller, and mulch film only could after reserved mulch film is depleted on lay-on roll
It is pulled down into coming.And the setting of suction nozzle and air jet pipe can be opened mulch film from lay-on roll while lay-on roll is rotated, from
And make to be always maintained at reserved mulch film between lay-on roll and membrane roller, and then pulling force of the membrane roller to mulch film is eliminated, mulch film institute
The pulling force received only has what air jet pipe and suction nozzle applied.
During original state, first is open and fumarole position consistency, and the second opening is consistent with the lead to the hole site in aspiration box,
Booster air pump and driving means, the air with pressure is sprayed by the outlet side of air jet pipe.The gas of ejection is on lay-on roll
Mulch film section imposes power upwards, and mulch film is separated from lay-on roll.Due to there are adhesive spots between mulch film, may be in the work of jet
Adhesive spots can not be completely disengaged from lower mulch film, now, driving means rotate with rotary column, and sector gear is also rotated with, and band
Moving gear rotate, and then first commutation cylinder and second commutation cylinder also begin to rotation, first commutation cylinder rotate when, therewith first opening
Slowly stagger with fumarole, air jet pipe stops jet.When second commutation cylinder rotates, second it is open and the through hole in aspiration box therewith
Stagger, complete pre- to take off film action.With the rotation of rotary column, two sector gears distinguish the cylinder that commutates with the first commutation cylinder and second again
On Gear Contact, and drive it to rotate.With the rotation of gear, the first commutation cylinder and the second commutation cylinder also begin to rotation, the
One opening slowly overlaps with lead to the hole site, second be open slowly overlaps with the position of suction hole, air by suction nozzle suction end
It is inhaled into, the suction end for causing suction nozzle has negative pressure, therefore mulch film can be held by the suction end of suction nozzle, with lay-on roll
Rotation, suction end can overcome the active force of adhesive spots to mulch film suction, mulch film is taken off completely.Thus, completing a cycle
Film action is taken off, now there is gap between mulch film and film roll, with the rotation of lay-on roll, mulch film can be from without drawing, also
Depart from film roll, and then keep there is reserved mulch film section always between lay-on roll and membrane roller.
The beneficial effect of this base case is：On the one hand by air jet pipe mulch film is carried out it is pre- take off film action, prevent directly
Mulch film is held using suction nozzle, when by the rotation of lay-on roll is taken off mulch film, due to the bonding force between mulch film it is excessive, will
Mulch film tears.Pre- due to air jet pipe takes off film action, and suction nozzle easily from lay-on roll can take mulch film off, will not be over the ground
Film causes larger pulling force, and it makes the mulch film section between lay-on roll and membrane roller only be subject to pulling force twice.On the other hand, we
While case overcomes bonding force, mulch film is opened from film roll, with the rotation of lay-on roll, the mulch film being lifted can be natural
Drop, be to reserve mulch film section between lay-on roll and membrane roller to create condition.After forming reserved mulch film section, membrane roller is only needed gram
Mulch film can just be pulled to next station by the gravity of the reserved mulch film section of clothes, and mulch film itself is frivolous, that is, need to apply reserved mulch film
Plus pulling force it is negligible.Furthermore the intermittence effect of air jet pipe and suction nozzle to mulch film, gives stress relieving in mulch film
Time.Biodegradable films are strong after the easy damaged and plastic film mulch of this programme Biodegradable films when plastic film mulch is solved in terms of three above
The low problem of degree.
Further, the sector is half knuckle-tooth, and two halves knuckle-tooth is projected as a full circle along rotary column axial direction.Two and half
Knuckle-tooth makes commutation cylinder continuously rotate, and the conversion interval time between jet and air-breathing reduces.
Further, the first opening and the second opening are in that the first Opening length is changed for first along the circumferentially disposed strip of outer wall
To the half of cylinder circumference girth, the second Opening length is the half of the second commutation cylinder circumference girth, and rotary column is located at jet box and inhales
Between gas box.After the turning over of half knuckle-tooth, the first opening also just staggers with corresponding fumarole or position overlaps, the second opening
Just overlap or stagger with the position of suction hole, make the conversion gapless between jet and air-breathing, mulch film is by the gas in air jet pipe
Body is blown afloat after coming, and suction nozzle forms at once negative pressure, and mulch film is adsorbed.The suction end and mulch film of suction nozzle are prevented apart from mistake
Far, it is impossible to which mulch film absorption is got up.
Further, the direction to lay-on roll film feeding is met in the outlet side of the air jet pipe.Because adhesive spots are located between mulch film
Gap, the outlet side of air jet pipe is met the direction to lay-on roll film feeding, i.e., against the position of adhesive spots, enables the gas of ejection
Mulch film is preferably acted on, mulch film separation from film roll is made.
Further, the lay-on roll and the equal diameters for drawing grinding roller.Make film feeding equal with the speed of membrane, will not be because sending mill
Speed difference between roller and drawing grinding roller, consumes reserved mulch film section.
