Mulch film spreading and seeding machine
Technical field
The utility model relates to the sower in a kind of film crop plantation, particularly the mulch film spreading and seeding machine in a kind of film crop plantation.
Background technology
The application of film crop plantation is at present very extensive, and particularly arid area, inland has become a kind of indispensable implantation methods.
Current film crop cropping pattern is generally divided into two kinds: the one, and before film, sowing, is first sown into seed in soil, and then covers upper mulch film, also cries under film and sows; Another kind is to sow after film, first mulch film is layed in to ground, and then adopts the mode of program request that seed is sown in soil through mulch film, also referred to as program request on film.
Before film, the maximum shortcoming of sowing is must put seedling operation after crop emerges, output a hole in the position of emerging of mulch film, crop seedling is freed from mulch film, this operation must be timely and also main dependence manually carry out, labour intensity is very large, as puts seedling and be easy to not in time cause temperature in the shed too high and seedling is scalded dead.
After film, sowing says theoretically and need not put seedling operation, but in practice, after plastic film mulch, seeding operation, film is not completely fixed, and need to carry out earthing operation, in the time of earthing operation, in a lot of situations, the kind hole on film and the kind cave on ground misplace, and earthing operation itself is also easy to cause kind of an appearance for hole inconsistent phenomenon, and then cause seedling not normally to be unearthed, or unearthed seedling is not in the kind hole site of film and tegmentum is pressed under film.
CN102027868A discloses a kind of covering unit of drill, after sowing plastic film mulch, on film, joint-cutting or punching earthing in institute's joint-cutting gap is exactly carried out in sowing position, to guarantee to allow the seedling can natural membrane, improves the quality of emerging.But in actual motion, to sowing position carry out joint-cutting or punching will be very earthing accurately and simultaneously, there is not dislocation in the Yu Zhong cave, kind hole that guarantee is got, operation easier is very large.
Therefore, a kind of film crop implantation methods and special sower of the method that can ensure that the Yu Zhong cave contraposition of mulch film kind hole accurately can't misplace just arises at the historic moment.
Summary of the invention
The purpose of this utility model is to provide a kind of mulch film spreading and seeding machine that can ensure that the Yu Zhong cave contraposition of mulch film kind hole accurately can't misplace.
The utility model comprises frame (2) and comprises mulch film the mulch film spreading equipment structure that rolls frame (5), Film opening roll (7), pressing wheel (8), its improvements are: after described mulch film spreading equipment structure, be provided with successively from front to back plastic film banking machine structure and film upper seeding wheel mechanism, described plastic film banking machine structure at least comprises soil-uncovering device (9) and conveying mechanism, and described film upper seeding wheel mechanism is the one in program request or drilling mechanism.
Described soil-uncovering device (9) is preferably cuts native disk, also can ploughshare or rotary cultivator attachment.
Described conveying mechanism is preferably flower basket type soil-covered drum (10), also can be rotary-type conveying mechanism, comprise the wheel body that is provided with spoke (14) and wheel rim (17), wheel body roller circle (17) inner side within one week, be provided with a page plate (15), this page of plate (15) and wheel rim (17) form to the inside the box-like or dustpan shape body of opening, simultaneously, wheel body inner side the box-like or dustpan shape body below of opening be to the inside provided with and connect soil bucket (16), this connects going to the bottom to mulch film lopsidedness and forming more than one soil outlet of soil bucket.
Certainly, conveying mechanism described in the utility model also can be conveyer belt type conveying mechanism or scraper conveyor structure.
Compared with prior art, the utility model can ensure that the Yu Zhong cave contraposition of mulch film kind hole accurately can't misplace at seeding time, and then ensures to allow the seedling can natural membrane, greatly improves the quality of emerging, and can need not put seedling completely simultaneously.

Embodiment
embodiment 1:with reference to Fig. 1, Fig. 2, it is the main structural representation of looking of the utility model embodiment 1, it is dibble seeder on film 4 row films, comprise hitch frame 1, frame 2 and comprise mulch film and roll frame 5, Film opening roll 7, the mulch film spreading equipment structure of pressing wheel 8, after described mulch film spreading equipment structure, be provided with successively from front to back plastic film banking machine structure and film upper seeding wheel mechanism, described plastic film banking machine structure comprises soil-uncovering device 9 and conveying mechanism, soil-uncovering device 9 is for cutting native disk, conveying mechanism is flower basket type soil-covered drum 10, described film upper seeding wheel mechanism comprises seed-box 12 and dibbler 11, dibbler 11 is Duckbilled dibbler 11, after dibbler 11, be provided with kind of a Kong Ping and comfort mechanism 13, the dibbling hole staying to smooth dibbler, the present embodiment kind Kong Ping comforts mechanism 13 for packer.
The utility model course of work is as follows: first carry out whole ground, then carry out laying plastic with sower of the present utility model and at film limit earthing, the mulch film top of putting at kind of acupuncture point is carried out earthing and is formed earthing band on film simultaneously, on film, program request sowing on film is carried out in earthing band position afterwards, then flat kind of the hole of comforting.
embodiment 2:with reference to Fig. 3, be the structural representation of the utility model embodiment 2, compared with embodiment 1, the difference of the present embodiment is: described mulch film spreading and seeding machine is dibble seeder on two film 8 row films.
embodiment 3:with reference to Fig. 4, Fig. 5, for the structural representation of the utility model embodiment 3, compared with embodiment before, the difference of the present embodiment is: the described conveying mechanism of described mulch film spreading and seeding machine is rotary-type conveying mechanism, comprise the wheel body that is provided with spoke 14 and wheel rim 17, wheel body roller circle 17 inner sides within one week, be provided with page plate 15, this page of plate 15 and wheel rim 17 form to the inside the box-like or dustpan shape body of opening, simultaneously, wheel body inner side the box-like or dustpan shape body below of opening be to the inside provided with and connect soil bucket 16, this connects going to the bottom to mulch film lopsidedness and forming two soil outlets of soil bucket, can on mulch film, form two earthing bands.After dibbler, the kind Kong Ping after dibbler 11 comforts mechanism 13 for hairbrush.
The mulch film spreading and seeding machine course of work is as follows: laying plastic at film limit earthing on the soil after smooth, soil is dug to send wheel rim 17 and drop on by page plate 15 and wheel rim 17 form to the inside in the box-like or dustpan shape body of opening by cutting native disk, when dustpan shape body turns to top with wheel body, soil is poured into and connect in soil bucket 16 and fall within mulch film and form earthing band from connecing the soil outlet of soil bucket, carry out program request on film by dibbler earthing band position on film afterwards and sow, then brush flat with hairbrush.
