Population height limiting plate regulation bolt 8 is fixed." 7 type " that the rectangle part of population height limiting plate 4 is stuck in seed inlet 306 both sides is protruding interior.
By changing the relative position adjustments population height of the circular hole on population height limiting plate 4 and the straight trough mouth 301 on housing 3.
Grid window 10 is stuck on housing 3 by " 7 type " projection of fan-shaped gas inlet mouth 308 both sides.
Chong Zhong district adjustable plate 5 is fixed on the inside of housing, fills the size in kind of region for regulation.As it is shown in figure 9, this fills kind
District's adjustable plate 5 is made up of two orthogonal plane regulating faces 501 and gear kind face 502.Plane regulating face 501 is parallel to housing
Blind end arrange, an end face in gear kind of face 502 contacts with the inner circumferential side of housing 3.Plane regulating face 501 has one bent
Wire casing 503, is fixed on Chong Zhong district adjustable plate 5 on housing 3 by the first boss 309 of curved groove 503 with circular hole.By changing
Curved groove 503 realizes the regulation in Chong Zhong district with the relative position of the boss I309 of circular hole.During regulation, meet gear kind all the time
One end face in face 502 overlaps with dividing plate 305, another end face in gear kind face 502 and side superimposed in housing 3 excircle.
As shown in Figure 10, kind of the plate 6 that unloads planted for unloading remaining group by arc section 601 and installs circular hole 602 two parts
Constitute.Installing circular hole 602 hinged with mounting ear 304, the inner side of arc section 601 embeds unloads kind of mouth 302, outside the parcel housing 3 of outside
Side circumference.One end of the remotely mounted circular hole of arc section 601 602 is fixed by leaf spring 7, and leaf spring 7 is for being fixed on outside housing 3 bottom surface
Side.
From above description, Seed-cleaning tool 2 can be by Seed-cleaning tool installation portion 202 long installing hole regulation Seed-cleaning tool distance row
Plant the distance of dish, the initial and final position in clear kind region can be regulated by strip hole 307.Chong Zhong district adjustable plate 5 is by changing
Curved groove 503 realizes the change in Chong Zhong district with the relative position of the boss I309 of circular hole.By changing the circle on population height limiting plate 4
The relative position adjustments population height of hole and the straight trough mouth 301 on housing 3.
Below according to Figure 11 to Figure 13, test of the present utility model is described former with the work of adjustable air-suction seeding unit
Reason.
Discharge plate 11 is arranged on the open end of housing 3 and can rotate, for entrained seed is discharged housing 3.
And air chamber and seed chamber are separated by discharge plate 11, and in air chamber, produce negative pressure.Discharge plate 11 regulates from Chong Zhong district
Start at plate 5 to contact with seed, and by type hole, the seed of seed chamber is adsorbed onto on the type hole of discharge plate 11.Seed is with seeding
Dish 11 turns to the position of Seed-cleaning tool 2.Unnecessary seed is wiped off by Seed-cleaning tool 2, only stays a seed to continue to revolve with discharge plate 11
Go to sowing port 303 and complete seeding.
By the position of regulation Chong Zhong district adjustable plate 5, change the first contact position of discharge plate 11 and seed, thus change
Fill the size of kind of region.By regulating the height of population height limiting plate 4, change the size of seed inlet 306, thus change population and exist
Height in seed chamber.
After the feed mechanism for seed end of job, unspent seed is by pulling leaf spring 7, and release unloads kind of plate 6, by seed from feed mechanism for seed
Lay down below procapsid, empty seed chamber, treat lower subjob.
The foregoing is only the specific embodiment of utility model, be not intended to this utility model is imposed any restrictions, every
According to this utility model it carried out etc. by change and modify, all within the category of the art of this patent protection scheme.
