Description
Technical field
The invention belongs to agricultural mechanical fields, are related to a kind of modern agriculture incomplete film-recovering machine, especially one kind is suitable for low
Gear tooth-type incomplete film-recovering machine on stubble crop plot.
Background technology
Mulching planting technique is the important component of modern agricultural production, has saving water, resisting drought, Meteorological effect, prevents
Cut weeds, cost-saving synergistic many advantages, such as.But China due to largely use relatively thin mulch, cause a large amount of residual films cannot and
Shi Huishou, the residual film left in the soil increase year by year, cause serious pollution to agricultural production and ecological environment, influence to make
Object development growth.In order to solve residual film leftover problem in soil, pollution is reduced, people invent and apply a variety of residual films in recent years
Recycling machinery.
After published crop harvesting used plastic collection machinery, winder step is all that 1, film side is loosened the soil, 2, loosening shovel will
Earth's surface residual film boosts, 3, film stir-up tooth provoke residual film, 4, the residual film provoked is unloaded by demoulding mechanism and is sent into collection membrane element.It is complete
At above-mentioned steps choose film, demoulding sum aggregate membrane element be influence winder effect core institution.It is existing to choose film, demoulding component
Structure type have the tooth-like collecting reel of telescopic rod, elastic claw type pick up membrane element, shovel rise stubble winder component, gear tooth-type winder component,
Toothed-chain type winder component.
The existing tooth-like pickup machine cylinder of telescopic rod is complicated, and cost is higher, and mechanism is complicated and performance is unreliable, simultaneously because machine
Structure decentraction, the presence of frictional force between expansion teeth and roller, more or less presence is certain between roller and Eccentric cylinder
Torsion；Elastic claw type, which picks up, needs the curvilinear path slideway of a control winder elastic claw operating position to be convenient in the demoulding component of membrane element
Demoulding, thus certain difficulty is brought to manufacture, meanwhile, this kind of winder component also cannot achieve the separation of residual film and weeds, machine
Structure is complicated and performance is unreliable；Shovel collecting machine has the performance of soil certain requirement, and the root for the residual film and crop packed up
Stubble mixes, and residual film contains miscellaneous height, can bring difficulty to the regeneration of residual film；Gear tooth-type collecting machine residual film and film lifting wheel shape
At winding, residual film is not easy to remove from film lifting wheel, time-consuming；Toothed-chain type collecting machine elastic claw demoulding is undesirable, residual film case
Residual film belongs to empty loose accumulation form, cannot efficiently use the volume space of collecting box.
Invention content
The purpose of the present invention is to provide a kind of power by tractor input, simple in structure and reliable operation, antiwind, de-

The top of structure；The Tiao Mo mechanisms are fixedly mounted on the film lifting wheel group on film lifting wheel axis by a film lifting wheel axis and multiple intervals
At having film stir-up tooth on film lifting wheel, the output shaft of film lifting wheel axis and gearbox passes through chain drive；The demoulding mechanism includes multiple
Identical demoulding unit, each demoulding unit are taken off by a cylindrical drum and one using the cylindrical drum outer circle as the involute of basic circle
Diaphragm plate forms, and the width of demoulding plate is equal with the height of cylindrical drum, and cylindrical drum is sleeved on film lifting wheel axis and is located at by axle sleeve
Between two adjacent film lifting wheels, one end of demoulding plate is welded on the surface of Correspondent cy linder cylinder, and the other end is fixed on film-collecting box bottom
On plate, gap between two neighboring demoulding plate formed film stir-up tooth by tooth socket；The film stir-up tooth is relative to involute
The front of the normal line direction tooth of demoulding plate, film stir-up tooth is vertical with the section of any contact point on demoulding plate involute curved surface.
Further, there are multiple axial keyways for installing film lifting wheel on the film lifting wheel axis.
Further, the film lifting wheel is Integral plate type structure, and uniform intervals are equipped with 2-6 film stir-up tooth thereon, film lifting wheel
Root radius is equal with the exradius of cylindrical drum.
Further, the front of the film stir-up tooth is tangent with root circle, and the back side of film stir-up tooth is arbitrary cambered surface.
Further, the height of the cylindrical drum is 8-20cm.
The invention has the characteristics that：
（1）The direction of rotation of film lifting wheel is consistent with the expansion direction of demoulding plate.In rotation process, film stir-up tooth will be native for Tiao Mo mechanisms
Residual film in earth is provoked, then is scraped by the demoulding plate of tooth socket both sides, and is pushed through in film-collecting box by film stir-up tooth.（2）Cylindrical drum is not
It is dynamic with film lifting wheel shaft rotation, winding of the residual film to film lifting wheel axis can be effectively prevent.（3）Film lifting wheel has residual film in rotation process
Into film-collecting box, push and squeezing action, film-collecting box can accommodate more residual film.（4）Interval between film lifting wheel can make soil
Block, plant undesirable root are smoothly being fallen by the stage of provoking, and will not bring film-collecting box by film stir-up tooth, you can realize residual film and soil block, plant
The separation of object undesirable root.
