Description
Technical field
The present invention relates to agricultural machinery technological field, specially a kind of wheat head progeny row for crop field experiment is sowed
Machine.
Background technique
Head progeny row breeding experiment is that cereal, beans new varieties enter the important link before area's examination and kind detection, seeding quality
Directly affect the accuracy of crop head progeny row comparative test.It is relatively flourishing since the research of China's breeding mechanical equipment is started late
For country, the breeding Mechanization Level in China still more falls behind, and 80% or more breeding production equipment needs external introduce.State
Outer field stock breeding machinery is expensive, and adequate and systematic service is relatively deficient in the specialized maintenance improvement personnel of China's field machinery,
The machinery of purchase can not be merged organically during actual job with local work pattern.Therefore, a kind of suitable China is researched and developed
Cropping pattern and agriculture requirement head progeny row seeder, for develop high yield, stable yields, good wheat breeding, improve wheat
Yield, the international competitiveness for promoting the grains germplasm such as China's wheat have great significance.
The requirement of head progeny row seeder is: to prevent variet complexity, need to uniformly finish in defined cell length a certain amount of
Seed, interval walking a distance after sow next cell again, the gap length between cell and cell must control standard
Really.Domestic traditional head progeny row seeder does not have automatic seed-feeding device and in the ranks synchronizes automatic control seed-dropping equipment, due to planning cell
Gap length is shorter, it is therefore desirable to and it shuts down before each cell is sowed and is manually charged seed, cause minizone operation discontinuous,
Again by the every row planting of manual control, the more difficult synchronization of planting in the ranks leads to long irregular, the cell gap length of cell sowing row
Control is not accurate, influences breeding precision.External more advanced head progeny row seeder has been provided with automatic seed-feeding device and synchronous control in the ranks
Seed-dropping equipment, but automatic seed-feeding device needs artificial triggering with the action signal of synchronous automatic control seed-dropping equipment in the ranks, that is, works
Before need in each cell setting flag, when reaching each cell sowing label, by manually pressing control button, for kind of device with
In the ranks synchronous control seed-dropping equipment can auto-action.Due to the generally existing error of manual control, lead to cell gap length control
System is not accurate, influences to test precision.
The automatic seed-feeding device of seeder in the prior art is generally adopted by electric putter, electric putter cannot be real
Now accurately for kind, while side being placed on before automatic seed-feeding device, center of gravity is biased to machine side, and it is unstable, while pushing block is
Iron pushing block, position is higher, is easy to overthrow in kind of a box, and secondly planting with sowing machine is more single, can not achieve the progress of multiple kinds
Sowing, the efficiency of work is lower, therefore needs to research and develop a kind of wheat head progeny row seeder for crop field experiment.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of wheat head progeny row seeder for crop field experiment
The wheat head progeny row seeder for crop field experiment proposed in background technique can not achieve accurately for kind, while automatically
For being placed on side before kind of device, center of gravity is biased to machine side, unstable, while pushing block is iron pushing block, and position is higher, is easy
Kind of a box is overthrown, secondly planting with sowing machine is more single, can not achieve multiple kinds and sow, the efficiency of work is lower
