Description
Technical field
An a kind of Room duplicate rows pneumatic seeder is the utility model is related to, is the device for agricultural machinery precision drilling,
Belong to agricultural machinery technological field.
Background technology
In recent years, China pays close attention to agricultural development, and wherein precision drilling is one of current agricultural equipment research important
Content.
At present, the feed mechanism for seed that the seeder in China uses 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
Do not solve the problems, such as wound kind and pulsation fundamentally.
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 a more preferable precise sowing performance, pneumatic seeder is extensive
Be applied to current precision drilling.The air-suction seeding unit that uses domestic at present is mostly table roller feed mechanism for seed, this kind of feed mechanism for seed
Effectively solves the problems, such as seeding pulsation relative to the feed mechanism for seed of machinery, 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 causing 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.Traditional plough has only served trench digging effect 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 solve seed
