Embodiment
As shown in Figure 1,1 is grain cover, and its central lumen is a seed chamber, and 2 are slotted disk radially, and 3 is the spiral slotted disk, and 4 is drive chuck, and 5 is sprocket wheel, and 6 is bearing, and 7 is air chamber, and 8 is seeder unit shell.Wherein, seeder unit shell 8 can be by being bolted on the sowing frame, and seeder unit shell 8 and air chamber 7 are fixed together by screw, and the locating slot of spiral slotted disk 3 blocks the pin on the air chamber 7 and maintains static.Sprocket wheel 5 welds together with drive chuck 4, support by the bearing 6 that is fixed on air chamber 7 housings, driving drive chuck 4 by sprocket wheel 5 transmissions rotates, three driving claws match with corresponding grooves on the radially slotted disk 2 of being close to spiral slotted disk 3 fronts on the drive chuck 4, thereby realize drive chuck 4 and being connected of slotted disk 2 radially, when drive chuck 4 rotates, radially also revolution synchronously thereupon of slotted disk 2.Grain cover 1 passes through bolt together with seeder unit shell 8, and radially the gap between slotted disk 2 and the grain cover 1 is 0-0.5mm, after assembling is finished, must not have stuck between each parts or the collision phenomenon generation.
Be close to the vertical seeding disk that overlaps for two, i.e. spiral slotted disk 3 and radially slotted disk 2 separate seed chamber on the grain cover 1 and air chamber 7.The back side of spiral slotted disk 3 is air chambers 7, and the inlet scoop on the seeder unit shell 8 is connected with blower fan, makes and produces negative pressure in the air chamber 7.Radially slotted disk 2 is close to spiral slotted disk 3 fronts, forms at the overlapping of radially slotted eye and spiral slotted eye and inhales the hole, and inhaling the place, hole has negative pressure, inhales the hole with the radially rotation of slotted disk 2, and it is outwards mobile press hand of helix by the center of dish.Grain cover 1 top has seed inlet, and from then on seed enters seed chamber.
As shown in Figure 2, the spiral slotted eye of spiral slotted disk 3 is from the curved circle that extends upward in disk center below, forms to inhale kind of a district, clearly plant the district and take kind of a district, with some slotted eyes stack formation combined suckers by near the outward radial radiation center of dish above the slotted disk 2 radially.Inhaling kind of a district, the rate of change of spiral slotted eye separation disc centre distance is little, and then the combined sucker area does not have significant change, is shaped as rectangle, helps inhaling the hole and is filling kind of district's absorbed seed; Plant the district clear, because spiral slotted eye helix rises, the rate of change of spiral slotted eye separation disc centre distance has experienced and has changed from small to big, and process from large to small makes the combined sucker area change from small to big, more from large to small again.In this change procedure, the shape of inhaling the hole also becomes parallelogram by inhaling kind of the rectangle in district, becomes rectangle by parallelogram again, the unnecessary seed that is adsorbed with removing; Take kind of a district, because the distance at spiral slotted eye separation disc center does not change, the combined sucker area is constant, and the suction hole shape is a rectangle, and the single seed that is left after helping planting clearly is in stable state and is carried into sowing port.
Operation principle is omnidistance combined sucker air-sucking type (see figure 3), during sower work, blower fan forms vacuum in air-suction chamber 7, combined sucker both sides in spiral slotted disk 3 and radially slotted disk 2 formation produce pressure differential, seed in the seed chamber 9 is adsorbed on the hole, and radially slotted disk 2 is driven by sprocket wheel 5 and does at the uniform velocity revolution simultaneously, radially in slotted disk 2 rotation processes, combined sucker moves along helicla flute, and the seed 9 that is adsorbed on the combined sucker is also outwards moved by the center along helicla flute with inhaling the hole.In moving process, because of inhaling hole shape with the radially constantly variation of rotation of slotted disk 2, earlier become parallelogram by approximate rectangle, after become approximate rectangle again, therefore, be adsorbed on the also and then rotation of seed 9 on the hole, cause seed 9 rotations location, at this moment the unnecessary seed 9 that suction the is not enough seed chamber that falls back, surplus at last seed 9 is adsorbed on the combined sucker, and at spiral groove end, combined sucker disappears, negative pressure also just disappears, and the seed that carries this moment so far directly falls in the kind ditch that plough leaves by gravity.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
