Embodiment
Describe embodiment of the present utility model in detail below in conjunction with drawings and Examples.
Structure of the present utility model as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, comprise housing 1, block species cover 2, hold-down nut 3, nest eye wheel shaft 4, ejector blade axle 5, torsion spring ejector blade 6, nest eye wheels 7, wing nut 9, end cap 10, plant seeds protecting plate 11, locating shim 17, voussoir 20 etc. clearly.Nest eye wheels 7 are installed in the housing of described seeding unit, by 3 different single hole rollers of nest eye volume size, formed, 3 single hole rollers are in tandem on nest eye wheel shaft 4 by the order of medium size nest eye 12, small size nest eye 13, large size nest eye 14 from left to right, and be supported on housing 1 by this nest eye wheel shaft 4, adopt 2 hold-down nuts, 3 restriction nest eye wheels 7 to move axially, nest eye wheel shaft 4 adopts six square shafts, with 7 moulding of nest eye wheels, is connected, and during work, is with the wheels 7 of starting moving to rotate together.
Exempt to change the further improvement of Type Seed Metering Device as a kind of many types of hole of the utility model, 3 block species covers 2 are arranged respectively at described 3 nest eyes wheel top, unclamp wing nut 9 and can make cambered way 8 slippages of block species cover 2 along housing 1 front portion, thereby make block species cover 2 stretch out or regain, easily realize the seeding of a certain specific nest eye wheel.It is consistent with nest eye wheels 7 direction of rotation that direction is stretched out in the slippage of block species cover 2, makes block species cover 2 maintain the trend of stretching out, and guarantees block species cover 2 gear kind of stability.
Exempt to change the further improvement of Type Seed Metering Device as a kind of many types of hole of the utility model, described clear kind of seeds protecting plate 11 is configured in the sidepiece of nest eye wheel, in housing 1 bottom, by bolt 15, be connected, its top dogleg section completes plants clearly function, and middle arc lower partly realizes protecting kind of a function.Described voussoir 20 is tangent with the clear seeds protecting plate 11 of planting, alignment pin 18 is arranged at top, guide finger 16 is arranged at bottom, can slide up and down along the slideway 22 at housing 1 rear portion, slideway 22 outsides have three detents 21, and slide up and down voussoir 20 locating shim 17 is coordinated from 3 different detents 21 on slideway 22, and with wing nut 19 locking positioning pads 17, can realize planting clearly three grades of adjustment of seeds protecting plate 11 and the spacing of nest eye wheel, to adapt to clear kind of different size seed, protect kind of needs.Described nest eye wheels 7 belows have 3 torsion spring ejector blades 6 to be arranged on housing 1 by 5 supportings of ejector blade axle, and torsion spring ejector blade 6 one ends stretch into the nest eye and take turns in the annular groove in single type hole, and the other end is supported on housing 1.
Exempt to change the described housing 1 of Type Seed Metering Device and all cylinder iron casting machineds again of end cap 10 as a kind of many types of hole of the utility model, the top and the bottom of housing 1 all are cast with rectangular through-hole, and housing 1 top is bolted kind of a case.
Operation principle
Operation principle of the present utility model is, nest eye wheel shaft obtains power by land wheel, be with a wheels of starting moving to rotate, corn seed rolls in the nest eye by deadweight, after clear kind plate scrapes off unnecessary seed, the seed of nest intraocular forwards below with the nest eye to along seeds protecting plate and goes out kind of a mouth, leans on gravity fall or is charged seed by force by ejector blade.
Adjustment process
Take turns current seeding nest eye while being not suitable with when the seed of required sowing and nest eye, just need be adjusted.During adjustment, unclamp wing nut, the block species cover that makes current seeding nest eye wheel top is along the slippage that makes progress of the cambered way on housing, and block species cover stretches out and covers this nest eye wheel, makes seed can't enter the nest eye, the locking wing nut.Select the nest eye wheel suitable with required sowing seed, same operation is regained block species cover, makes it in filling kind of a state, completes once and adjusts.
When the spacing of clear kind of seeds protecting plate and nest eye wheel is improper, unclamp wing nut, make locating shim break away from detent, sliding up and down voussoir coordinates the different detent of locating shim, and with wing nut locking positioning pad, can realize planting clearly the once adjustment of the spacing of seeds protecting plate and nest eye wheel.
