Description
Technical field
It is relevant with seeding machinery the present invention relates to agricultural mechanical field.
Background technology
Corn directional planting was started from before halfth century, and oneself is acknowledged as improving a new technology of corn per unit area yield, equal
Under the conditions of, can improve planting density 10%-15%, increase production 5%-10%, in recent years it has been reported that, increased production with the method highest
Amplitude has more than 40%.Due to corn directional planting technical sophistication, difficulty is too big, so far practical application area very little, and
All still manually put and transplant to realize after kind or artificial breeding.In addition input labour is excessive, and comparative effectiveness is not high, therefore pushes away
It is wide difficult.Change this situation, it is necessary to have suitable special-purpose machinery.But, in existing seeding machinary, there is not yet
Corn orients the figure of seeder, has also had not seen relevant report.
Current National is being carried out adjusting and reducing maize sown area on a large scale, and corn unit plane can be increased substantially by promoting this
The advanced technology of product yield, is particularly badly in need of.
The content of the invention
The maximum difficult point of corn directional planting is to orient the direction and location into after kind and seeding.Corn of the present invention orients disk nursery
The purpose of seeder, is to provide for a kind of novel corn that can orient the energy direction and location into after kind and seeding and orients seeder,
While realizing disk nursery orientation sowing, live and corn the mechanization directional transplant of orientation of corn is realized, to adapt to big rule
The need for mould corn directional planting.
Corn of the present invention orients disk seedling-culturing sowing machine, and it includes:
1) there is profiling hole on discharging tube, stopper and the main shaft at discharging tube two ends coordinate;
2) having in the middle part of main shaft in row's blind hole, blind hole has spring and ball;
3) limit kind plate and limit kind bar coordinate with discharging tube, component species room;
4) there are seed adjustment bar and seed adjustment piece on driving lever;
5) plant in case and clear kind cylinder is set, clear cylinder axle two ends of planting are with planting tank wall cooperation.
Discharging tube is arranged in some all rows by center line of perimeter line, and row arranges several profiling holes weekly, and profiling hole is ellipse
Manhole, the wall thickness of discharging tube and the consistency of thickness of seed flat horizontal surface, the two ends of discharging tube have stopper to coordinate with main shaft, seeding
Protrusive board is fixed in fixed chain wheels A and gear C in the stopper of pipe one end, the stopper of the discharging tube other end.
There are several blind round hole to be arranged in a row along axis in the middle part of main shaft, the profiling hole with discharging tube is corresponding, in blind hole
Spring and ball are placed, main shaft two ends are fixed on support two ends.
Limited kind of bar on limit kind plate, limit kind bar is by the number of packets in profiling hole on discharging tube, and every group has several oblique rows
The limit kind bar of row, every two limit kind bars coordinate the spacing on the inside of component species room, limit kind plate between discharging tube to be more than with discharging tube
The thickness of seed flat horizontal surface, less than the width of seed flat horizontal surface, the spacing between limit kind bar and limit kind bar is flat slightly larger than seed
The width in face, enables seed to enter profiling hole with tabular morphology, limit kind plate slightly arc is fixed on support.
Kind of case by kind of tank wall and plant bottom combinatorial surface into, plant set in case it is clear plant cylinder, it is clear plant cylinder axle two ends and stretch out plant a tank wall
Outside, the clear one end fixed gear D for planting cylinder axle outside kind of tank wall is engaged with the gear B being fixed on kind of tank wall, plants bottom with dialling
Bar coordinates, and plants case and rides over discharging tube and be fixed on support on limit kind plate.
Driving lever two ends are stretched out outside kind of tank wall, and one end coordinates with protrusive board, and the other end coordinates with spring base and spring, in spring
Under effect, the vibration produced by driving lever hits protrusive board makes seed fall into diagonally disposed kind room in an orderly manner by the gravity of itself
In, there are seed adjustment bar and seed adjustment piece on driving lever, seed adjustment bar is longitudinally inserted between limit kind plate and discharging tube, seed adjustment piece is on limit kind plate
Edge is placed on kind of bottom and discharging tube.
The bearing block of gear A is fixed on frame, gear A and the gear B being fixed on kind of tank wall and is fixed on discharging tube
Gear C coordinate, gear B and be fixed on the clear gear D planted on cylinder and coordinate, chain with the sprocket wheel A and roller A on discharging tube
Sprocket wheel B coordinates, and roller A and roller B coordinate with conveyer belt, the connected crank handle of afterbody of gear A axle, and shield kind is fixed in support side
Watt, the fixed scraping bar in lower section in the middle part of support, foot stool is fixed on frame.
