Description
Technical field
The present invention relates to a kind of Room duplicate rows pneumatic seeder, it is the device for agricultural machinery precision drilling, belongs to
Agricultural machinery technological field.
Background technology
In recent years, China's close attention agricultural development, wherein precision drilling are one of current agricultural equipment research important
Content.
At present, the feed mechanism for seed that the seeder of China is used is mainly external recessing, traditional outer groove wheel seeding
Easily hinder kind during device seeding, and the amount of broadcasting is big, pulsation phenomenon is serious, although some existing scholars propose helicla flute feed mechanism for seed, but still
Not the problem of not solving wound kind fundamentally and pulse.
Pneumatic type sowing be at present both at home and abroad research seed placing device when frequently with scheme.Pneumatic type sowing mainly has
Aspirated-air type and air-sweeping type seeding, because air-suction seeding unit has more preferable precise sowing performance, pneumatic seeder is extensive
Be applied to current precision drilling.The domestic air-suction seeding unit used is generally table roller feed mechanism for seed, this kind of feed mechanism for seed at present
Feed mechanism for seed relative to machinery effectively solves the problem of seeding is pulsed, and seeding precision and quantity have also obtained effective control
System.It is high to the requirement on machining accuracy of single unit system but this table roller feed mechanism for seed needs higher air-tightness, and this kind of seeding
The each seeding apparatus monomer of device can only broadcast a line seed, and causing seeder entirety, in the ranks seeding apparatus amount of monomer is more, especially
It is not suitable for the wide-and narrow-row seeding method of current some crops such as corn, wheat, easily causes the agricultural machinery in no-tillage seeding yet
The blocking of tool.In recent years, also someone devises a kind of gas that two table roller air-suction seeding units are combined into a feed mechanism for seed
Draught type seed sowing device, but the combination part air-tightness of this combined seed-sowing mechanism is poor, and also device breadth is larger, and complete machine is heavy,
Versatility is not strong, easily causes the blocking in the ranks of seeder.
At present, during planting with sowing machine, seed is directly fallen into out again via seed spout from a high position after feed mechanism for seed discharge mostly
In the kind ditch that ditch device is outputed, because seed is fallen from above, with higher speed so as to cause seed when seed falls into soil
Bounced in kind of ditch, the uniformity for causing seed to be distributed in kind of ditch is poor.Trench digging effect has been only served traditional plough more,
Also there are some ploughs that there is bottom of trench shaping function at present, trench digging creates smooth kind bed simultaneously, but still fails to solve seed
The problem of spring fallen from a high position and skewness.
Accordingly, it would be desirable to design a kind of simple and compact for structure, air-tightness is good, and the function with precision drilling makes seed in kind
The seeder being evenly distributed in ditch is to meet the agriculture requirement of current precision drilling.

Fall into afterwards in the kind ditch that plough is outputed, the drag chain for being articulated in planter rear portion is carrying out earthing, last town to seed
Pinch roller realizes that being covered in the uniform of soil on seed effectively suppresses under advance effect.
The present invention realizes and two row seeds is discharged in a sealed gas chamber, one is broadcast using the principle of aspirated-air type seeding
Plant monomer and broadcast two row seeds, complete the workload of two planters of traditional seeder, the width for the crops that are particularly suitable for use in
Narrow-row drilling.Air-suction seeding unit improves the uniformity of seed, and the structure of a Room duplicate rows efficiently utilizes air pressure, closed knot
Structure is good；One Room duplicate rows is simple in construction, reduces the width of seeding apparatus, effectively increases operating efficiency and the field of seeding apparatus
By property.Seed falls into kind of a ditch with kind groove in plough, reduces the height of seed planting, reduces when seed lands in field
Bounce, add the uniformity that seed is distributed in field.The Room duplicate rows pneumatic seeder of the present invention, which is efficiently solved, to be broadcast
Kind of machine realizes seed in field in the congestion problems of field work, and spring problem of seed when falling into kind of ditch by feed mechanism for seed
Between equally distributed function.
Finally it should be noted that above example is only unrestricted to illustrate technical solution of the present invention, although ginseng
The present invention is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to the present invention
Technical scheme modify or equivalent substitute, without departing from the spirit and scope of technical solution of the present invention, it all should cover
In invention right.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
