Description
Technical field
The invention belongs to agricultural machinery technological field, and in particular to a kind of seeder, more particularly to a kind of to be applied to wheat
The miniature seeding machine of cell scientific research and experiment.
Background technology
Wheat is one of generalized grain crop of China two, and long-term cultivated area is more than 2,000 ten thousand hectares.Country pays much attention to small
The scientific research and experiment of wheat, all put into substantial amounts of research funding every year, set up large quantities of scientific research projects.The sowing of wheat cell
It is the important step of wheat scientific research and experiment.The research of China's plant planter relatively lags behind, since early seventies successively
Introduce cone grid tray type and pneumatic type seeder, although seeding accuracy and efficiency are higher, but be not suitable for China's national situation and breeding
Method.The technical staff of China also successively have developed many types, certain not enough because existing, it is impossible to which fully meeting experiment sowing will
Ask, using less；The plant planter used at present is higher due to height of charging seed, and although feed mechanism for seed starts to unload kind, and seed needs
Seed furrow can be just fallen into after certain time, whereabouts certain altitude, now seeder has advanced a segment distance, starts to broadcast every time
There is one section of broadcast leakage phenomenon in the row capital planted.It is also the major reason for causing the first broadcast leakage of row that seeder, which starts to sow running clearance,.Throw
Plant height and also create seeder after end of line pause, the seed in seeding pipe stroke can fall at one, cause end of line seed
Replay packing phenomenon.The current first broadcast leakage length of plant planter row is more than 30 centimetres.Row head broadcast leakage length and height of charging seed, are opened
The sowing running clearance size that begins and speed of drilling are relevant.Feed mechanism for seed setting height(from bottom) is higher, start sowing running clearance it is bigger, broadcast
Plant the first broadcast leakage distance of the faster row of speed longer；Feed mechanism for seed setting height(from bottom) is lower, start sowing running clearance it is smaller, speed of drilling is got over
The first broadcast leakage distance of small row is shorter.End of line replay degree is relevant with feed mechanism for seed setting height(from bottom), and feed mechanism for seed setting height(from bottom) is higher, end of line weight
Broadcast grain number more；Feed mechanism for seed setting height(from bottom) is lower, and it is fewer that end of line replays grain number.The wheat plant planter end of line weight used at present
Grain number is broadcast more than 5, row head broadcast leakages and end of line replay are the major reasons for causing test error.Cell is sowed, and material is more,

Holding time proportion can be bigger.The current seeder method of planting clearly has following 4 kinds：Centrum grid tray type seeder from heat-clearing method, pass through
Gearratio is adjusted, the quantitative seed being dispersed in lattice disk is just finished in regulation row length；The strength of pneumatic type seeder plants clearly method；
The taking out of some centrifugal disc type hole formula seeders unloads seed-box and plants method clearly；Wheeled and outer groove wheel seeder the external force of type hole is rotated
Method is planted clearly in the seeding of land wheel.Although cone grid tray type seeder has from cleaning function, covering regulation row length, just lattice disk rotates one
Circle finishes all seeds, but is due to that site preparation quality is uneven, and land wheel skidding coefficient is inconsistent, often occurs to empty now
As the machine can not realize simple grain program request, be only used for cell sowing, and cannot be used for the sowing of plant head progeny row.Pneumatic type is broadcast
The machine of kind is larger because of impedimenta, and radius of turn is big, it is impossible to be used in plant head progeny row is sowed.Take out unload seed-box plant clearly method than external force rotate land wheel
Kind method is planted facilitates many clearly clearly, and speed is planted clearly, if but for the sowing of plant head progeny row, clearly, two rows one are clear, clearly for a line one
Time shared by kind is more, and sowing efficiency is low.
