Description
Technical field
The present invention relates to the technical field of agricultural machinery implanted device.
Background technology
Air-suction seed metering device includes negative pressure chamber, seed chamber and the big critical piece of sucker three, sucker isolation negative pressure chamber and seed chamber.
Negative pressure chamber generates air negative pressure in the presence of blower fan during work, produces the suction hole on sucker and flows to negative pressure from seed chamber
The air-flow of room, air-flow drives the seed in seed chamber to be close to the suction hole of sucker.With the rotation of sucker, being attached to suction hole
Seed takes feed mechanism for seed out of, and negative pressure is eliminated after going to negative pressure chamber border, and seed is discharged under gravity, realizes the purpose of sowing.
Current air-suction seed metering device abroad with China northeast, the Northwest's extensive use, be mainly used in seeding corn,
Soybean, cotton, sunflower etc., but it is not suitable for China's Huang, Huaihe River, Haiti area seeding corn.Practised mainly due to this area's corn seeding
After being used to summer getting wheat, directly sowed in field from which wheat has been reaped.The air negative pressure that air-suction seed metering device is produced easily sucks wheat straw or wheat
The debris such as chaff, cause feed mechanism for seed to block, and influence normal operation.
In order to solve the problems, such as that the debris such as wheat straw or wheat bran block air-suction seed metering device, somebody attempts raising feed mechanism for seed
Highly, but after feed mechanism for seed is increased, height of charging seed also is increased, and the problem that spacing in the rows is inaccurate is brought again.
The content of the invention
The subject matter that the present invention is solved is to provide a kind of air-suction seed metering device, solves the blocking of the debris such as wheat straw and wheat bran
Problem, will not suck the debris such as wheat straw or wheat bran, it is ensured that normal seeding operation.It is particularly well-suited to China's Huang, Huaihe River, the sowing of Haiti area
Corn.
Main technical schemes of the invention are：A kind of air-suction seed metering device, mainly including being evenly equipped with negative pressure chamber, side surface circumference
The rotation suction cup of suction hole, seed chamber, rotation suction cup segmentation negative pressure chamber and seed chamber are sliding between negative pressure chamber and rotation suction cup
It is dynamic to coordinate, it is characterized in that：Inlet plenum is provided with, seed chamber adds kind of a mouth to be provided with closing cap, and inlet plenum is located at seed chamber side, seed chamber
UNICOM mouthful is provided between inlet plenum, inlet plenum is in communication with the outside by filter；The bottom of negative pressure chamber is provided with pressure release seeding chamber, extremely
A seed for suction hole can be drained less.
Improved structure is to be provided with to deposit to plant below described pressure release seeding chamber to lead kind of wheel and its a shell, leads kind of wheel in shell
Interior rotation, the bottom of the shell is provided with mouth of charging seed；Deposit and kind lead kind between wheel and rotation suction cup by synchronization mechanism driver
Structure is connected.
Preferably, described synchronization mechanism transmission mechanism is gear pair.
Preferably, it is described to deposit that kind to lead kind of a structure for wheel be to deposit kind to lead kind of a peripheral distribution for wheel and have to fill kind of a ditch, fill kind of ditch
Position is corresponding when rotating with the position of the suction hole of sucker.
It is described to deposit in kind of the quantity for filling kind of ditch and rotation suction cup led on kind of wheel when preferably, using monoseeding
The quantity of suction hole is identical；Or, when being sowed using many, the quantity and suction hole quantity ratio for filling kind of ditch are 1:N, is more than 1
Natural number.
Described depositing kind is led kind of a structure for wheel and is, described to deposit the suction kind filled on circle where kind of ditch and sucker kind led on kind of wheel
The common factor of circle where hole, is located at corresponding kind of a wheel of leading in occuring simultaneously and fills in kind of ditch at the pressure release outflow of the seed in seed suction hole
The heart.
The positive effect of the present invention is：Compared with the prior art, the blockage problem of the debris such as wheat straw and wheat bran is solved, no
The debris such as wheat straw or wheat bran can be sucked, it is ensured that normal seeding operation, and ensure that spacing in the rows is accurate.It is particularly well-suited to China's Huang, Huaihe River, sea
Regional seeding corn.
Seed chamber is isolated from the outside during work, and air-flow can only be supplied from newly-increased inlet plenum, because inlet plenum increased
Filter, it is ensured that the debris such as wheat straw or wheat bran do not enter feed mechanism for seed.
The terrain clearance of feed mechanism for seed is increased, is increased to deposit to plant in the space that feed mechanism for seed and ground are increased and is led kind of a wheel.After increasing
Air-suction seed metering device away from the wheat straw and wheat bran on ground, further avoid the debris such as wheat straw or wheat bran from entering feed mechanism for seed.Seed is
It is last kind to lead kind of a wheel discharge by depositing, deposit and kind lead kind of wheel from the ground apart from close, so height of being charged seed after feed mechanism for seed is increased can not increase
Plus, therefore ensure that spacing in the rows is accurate.
It is described further below in conjunction with accompanying drawing and preferred embodiment, but not as limiting the scope of the present invention.
