Summary of the invention
The utility model proposes a kind of disk air-sucking type dispenser that is applicable to sow the drilling crops such as wheat.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of disk air-sucking type dispenser, mainly by hollow shaft, screw, left disk, right disk, stationary hub, sprocket wheel, bearing, bolt, sealing ring, trapezoidal planting sheet, flange, projection forms, 12 groups of disks equidistantly are contained on hollow shaft feeling at ease, every group of disk is comprised of left disk and the right disk that two external diameters equate, two relative side Excircle machinings of disk have chamfering and flange, flange forms the vacuum die cavity relatively, have uniform circular hole along circumference on the position of installation disk on hollow shaft, outside suction fan is passed through hollow shaft, the hollow shaft circular hole, disk vacuum die cavity, the suction kind groove part that relative disk forms, realized the absorption to drilling crop seeds such as wheats, the dispenser below is provided with trapezoidal planting sheet, the absorption affinity that makes seed break away from dispenser falls into the inoculation box, the right disk of every group of disk is equipped with stationary hub by screw, utilize stay bolt that stationary hub is fixed on hollow shaft, left disk and right disk are fitted together by three set screws, and every group of disk rotates with the rotation of hollow shaft.
The beneficial effects of the utility model are: the first, and utilize negative pressure of vacuum to inhale kind of a principle, injuring-free seed.The second, seed is inhaled kind of a groove part along the disk cylindrical and is vertically distributed, and Seeding Uniformity is good, and stability is high.The 3rd, simple in structure, convenient processing and manufacture is conducive to reduce costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure chart of disk in the utility model.
In figure, hollow shaft 1, screw 2, left disk 3, right disk 4, stationary hub 5, sprocket wheel 6, bearing 7, bolt 8, sealing ring 9, trapezoidal planting sheet 10 is inhaled kind of a groove part 11, flange 12, projection 13, cutting 14.
Embodiment
A kind of disk air-sucking type dispenser structure that is used for the drilling crop sowings such as wheat forms with reference to accompanying drawing 1.Each sowing row has one group of disk, and each is organized disk and is comprised of left disk 3 and the right disk 4 that external diameter equates, and equidistantly is contained on hollow shaft 1 feeling at ease.each disk inboard is processed with three with the projection 13 of screw, left disk 3 and right disk 4 fit together by three screws 2, the height of projection 13 is controlled the width of inhaling kind of groove part 11 between two disks, the central shaft hole of each disk has groove along circumference, inlay rubber seal 9 in groove, the right disk 4 of every group of disk is equipped with stationary hub 5 by screw, utilize stay bolt 8 that stationary hub 5 is fixed on hollow shaft 1, 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 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 the vacuum die cavity relatively, have uniform circular hole along circumference on the position of installation disk on hollow shaft 1, outside suction fan vertically is adsorbed on seeds such as wheats the suction kind groove part 11 that the left and right disk forms by hollow shaft, hollow shaft circular hole, disk vacuum die cavity equably.Left disk 3 and right disk 4 form suction kind groove part 11 belows are provided with trapezoidal planting sheet 10, and the absorption affinity that makes seed break away from dispenser falls into the inoculation box, realizes stable, evenly seeding, and trapezoidal planting sheet 10 is fixed on kind of case.
