Description
Art
The present invention relates to the dispenser of sower in a kind of agricultural machinery, particularly a kind of disk air-sucking type dispenser.
Background technology
Seeding unit is one of critical component affecting planting with sowing machine precision and seeding quality.Seeding unit conventional is at present divided into mechanical type and pneumatic type two kinds, and negative pressure aspiration is a kind of form conventional in Pneumatic seeding apparatus.Air-suction seeding unit conventional in production is mainly used in the bunch planting such as seeding corn, soybean or program request crop, the seeding unit of drilling crop (such as wheat) mostly is fluted-roller feed mechanism, it exists, and seeding pulsating nature is large, the not high defect of lack of homogeneity, stability, is difficult to the agriculture requirement reaching sowing seeds technology.National inventing patent " circular tube clearance type air-suction seed-sowing device " (patent No.: ZL200810212285.X) proposes a kind of circular tube air-suction formula dispenser, find in production and application, this apparatus structure is complicated, manufacturing cost is high, sowing stability and uniformity are better than mechanical seed sowing device, but still do not reach the agriculture requirement of precision drilling.Therefore, develop a kind of cost is low, structure is simple, seeding uniformity is good drilling crop seeding unit especially wheat seeding unit there is very important realistic meaning.
Summary of the invention
The present invention proposes a kind of disk air-sucking type dispenser being applicable to sow the drilling crops such as wheat.
The technical solution adopted for the present invention to solve the technical problems is: 12 groups of disks are equidistantly contained in hollow shaft to feeling at ease, often organize disk to be made up of the disk that left and right two external diameters are equal, the side Excircle machining that two disks are relative has chamfering and flange, flange forms disk vacuum die cavity relatively, and the position of hollow shaft being installed disk circumferentially has uniform circular hole.The suction kind groove part that external air suction blower fan is formed by hollow shaft, the circular hole of hollow shaft, disk vacuum die cavity, opposed discs, achieves the absorption to drilling crop seeds such as wheats.Be provided with trapezoidal seed-dropping equipment below dispenser, the absorption affinity making seed depart from dispenser falls into inoculation box, realizes stablizing, evenly sowing.
The invention has the beneficial effects as follows: the first, utilize negative pressure of vacuum to inhale kind of a principle, injuring-free seed.The second, seed inhales kind of a groove part genesis analysis along disk cylindrical, and Seeding Uniformity is good, and stability is high.3rd, structure is simple, and convenient processing and manufacture, is conducive to reducing costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structure chart of disk in the present invention.
In figure, hollow shaft 1, screw 2, left disk 3, right disk 4, stationary hub 5, sprocket wheel 6, bearing 7, stay bolt 8, sealing ring 9, trapezoidal planting sheet 10, inhales kind of a groove part 11, flange 12, and protruding 13, cutting 14.
Embodiment
For a kind of disk air-sucking type dispenser structure composition reference accompanying drawing 1 of the drilling crop sowings such as wheat.Each sowing row has one group of disk, and each group disk is made up of the equal left disk 3 of external diameter and right disk 4, and is equidistantly contained in hollow shaft 1 feeling at ease.The projection 13 of three band screws is processed with inside each disk, left disk 3 and right disk 4 are fitted together by three screws 2, the width of kind of groove part 11 is inhaled between Altitude control two disk of protruding 13, the central shaft hole of each disk circumferentially has groove, rubber seal 9 is inlayed in groove, the right disk 4 often organizing disk is provided with stationary hub 5 by screw, stay bolt 8 is utilized to be fixed in hollow shaft 1 by stationary hub 5, disk rotates with the rotation of hollow shaft 1, and then realize seeding, the two ends of hollow shaft 1 are fixed with sprocket wheel 6 by stay bolt 8, hollow shaft 1 is by sprocket wheel 6 driven rotary.The side Excircle machining that left disk 3 is relative with right disk 4 has chamfering and flange 12, flange 12 forms disk vacuum die cavity relatively, the position of hollow shaft 1 being installed disk circumferentially has uniform circular hole, and the seeds such as wheat to be longitudinally adsorbed on by the circular hole of hollow shaft, hollow shaft, disk vacuum die cavity the suction kind groove part 11 that left and right disk formed by external air suction blower fan equably.Be provided with trapezoidal planting sheet 10 below the suction kind groove part 11 that left disk 3 and right disk 4 are formed, the absorption affinity making seed depart from dispenser falls into inoculation box, and realize stable, evenly seeding, trapezoidal planting sheet 10 is fixed on kind of case.
The direction of rotation of disk is represented for arrow in the structure reference accompanying drawing 2, figure of left disk 3 in a kind of disk air-sucking type dispenser of the drilling crop sowings such as wheat.Left disk 3 is all processed with 45 ° of chamferings with the outer inner round side of right disk 4, fillet surface is processed cutting 14, the direction of rotation of cutting 14 from inside to outside along disk on fillet surface tilts 15 °, it is 75 ° with the angle of external arc tangential direction, cutting 14 drives Seed Layer, is convenient to more evenly, reliably fill kind.Left disk 3 circumferentially has groove with the central shaft hole of right disk 4, inlays rubber seal 9 in groove, ensures the sealing of vacuum suction cavity.
