Corn double-ridge mulch sowing combine
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of corn double-ridge mulch sowing combine that adopts plastic membrane.
Background technology
In recent years, a kind of employing is lay mulch film on surface, platform soil, ridge first, then combine dazzling on the mulch film of lay and that complete seeding operation is widely applied in corn seeding agricultural operation, owing to having completed continuously laying plastic and dazzling seeding operation in one-stop operation, because its operation continuity is good, operating efficiency is compared with high, be subject to user and welcome.But, on such integration of operation facility, for meet and complete dazzling on mulch film after seeding operation requirement again, generally adopt and be equipped with duck-beak type sowing rotary drum as its operation part, during its operation, closure state is dazzling, sowing while penetrating interior rear unlatching of kind of bed soil, and from rising in kind of bed soil, withdraw under duckbilled opening, then only rely on seed Soil Surrounding natural back flow to complete the covering to seed.In production practices, rely on seed Soil Surrounding gravity flow covering quality and effect poor, sometimes do not reach mulching soil thickness and tightness agriculture requirement, soil moisture is large, consistency of soil large, in the soil of poor fluidity, even there is the exposed phenomenon of seed, significantly reduced seeding operation quality.
Summary of the invention
The object of the invention is exactly the problem existing for above-mentioned prior art, design provides a kind of corn double-ridge mulch sowing operation combination machine of new construction, by adopting machinery to banket above seed in kind of bed, the mode of kind of subcovering is completed to the operation of seed earthing, the object of corn seeding operation quality after reaching assurance and improving overlay film.
The object of the invention is achieved in that corn double-ridge mulch sowing combine comprises frame and is fitted in the ridge body reshaper in frame, film limit plough, ground film roller frame, covering device between the two ridges of mulch film, film limit pressing wheel, film limit covering device, duck-beak type sowing rotary drum, land wheel and fertile case, fertilizer delivering pipe is communicated with fertile case with ridge body reshaper, in frame, be equipped with respectively soil-collecting device, the defeated native assembly of chain-and-harrow type, groove type earthing roller and power transmission box, described soil-collecting device is positioned at body reshaper the place ahead, ridge, the soil inlet port of the defeated native assembly front end of chain-and-harrow type is positioned at soil-collecting device rear side, power transmission box is connected with the defeated native assembly power transmission of chain-and-harrow type, described groove type earthing roller configuration is at the rear of duck-beak type sowing rotary drum, driving chain is connected duck-beak type sowing rotary drum with groove type earthing roller transmission of power, the soil outlet of the defeated native assembly of described chain-and-harrow type rear end is positioned at groove type earthing roller top.
The invention structural design is new reasonable, and seeding operation quality is good, and operating efficiency is high, uses reliably, and fault is few.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.A kind of corn double-ridge mulch sowing combine comprises frame 4 and is fitted in the ridge body reshaper 2 in frame 4, film limit plough 3, ground film roller frame 5, covering device 6 between the two ridges of mulch film, film limit pressing wheel 7, film limit covering device 8, duck-beak type sowing rotary drum 9, land wheel 10 and fertile case 13, fertilizer delivering pipe 14 is communicated with fertile case 13 with ridge body reshaper 2, in frame 4, be equipped with respectively soil-collecting device 1, the defeated native assembly 12 of chain-and-harrow type, groove type earthing roller 11 and power transmission box 15, described soil-collecting device 1 is positioned at body reshaper 2 the place aheads, ridge, the soil inlet port of defeated native assembly 12 front ends of chain-and-harrow type is positioned at soil-collecting device 1 rear side, power transmission box 15 is connected with defeated native assembly 12 power transmissions of chain-and-harrow type, described groove type earthing roller 11 is configured in the rear of duck-beak type sowing rotary drum 9, driving chain 16 is connected duck-beak type sowing rotary drum 9 with groove type earthing roller 11 transmission of power, the soil outlet of the defeated native assembly of described chain-and-harrow type 12 rear ends is positioned at groove type earthing roller 11 tops.
During operation, ground film roller is fitted on ground film roller frame 5 rotationally, dynamic power machine traction the machine moves ahead, ridge body reshaper 2, film limit plough 3, ground film roller frame 5, covering device 6 between the two ridges of mulch film, film limit pressing wheel 7, film limit covering device 8 and duck-beak type sowing rotary drum 9 successively complete ridge body shaping successively, film limit trench digging, mulch film lay, mulch film earthing between two ridges, film limit press mold, film limit earthing and mulch film are pricked seeding operation in the kind bed soil of hole, synchronous therewith, the defeated native assembly 12 of power transmission box 15 drive chain rake is delivered to outlet end by the concentrated part soil of soil-collecting device 1 from its feeding mouth end and is discharged, the duck-beak type sowing rotary drum 9 of rotation drives groove type earthing roller 11 to rotate by driving chain 16, the soil that the defeated native assembly 12 of chain-and-harrow type is discharged is filled with in the groove on groove type earthing roller 11 surfaces successively, soil in rotation process further groove falls into and covers the top that is sown into seed in kind of bed, fulfil assignment.
