2 be the center of circle, on the reference circle of diameter 165mm, and three adsorption holes 212 of every group of Kong Qun are distributed on the reference circle of diameter 10mm,
A diameter of 1mm of adsorption hole 212, it is each to organize 40 degree of hole group interval, adsorb in practice bore dia can according to seed decision size,
8-24 groups may be selected according to agriculture requirement in Kong Qunke.
Every group of hole group corresponds to one respectively and scoops kind of spoon 22, and it is in arc-shaped to scoop kind of spoon 22, and scoops the concave surface of kind of spoon 22 towards hole
Group, each scooping the setting of kind of spoon 22, there are two the gear kind protrusion 23 being set up in parallel, axial cloth of the gear kind protrusion 23 along adsorption hole 212
It sets, i.e. gear kind protrusion 23 is parallel with the axial direction of adsorption hole 212.It is steel alloy material to scoop kind of spoon 22 and disk ontology 21, scoops kind
Spoon 22 is welded in disk ontology 21 by way of fillet welding.Gear kind protrusion 23 is welded in by way of fillet welding scoops kind of spoon 22, scoops kind
It requires welding uniformly between spoon 22 and gear kind protrusion 23 and seals, seeds-blocking phenomenon cannot occur.It actually keeps off kind of protrusion 23 and scoops
Kind spoon 22 can be integrally formed structure.The specification of gear kind protrusion 23 is long 4mm, high 0.4mm, wide 0.3mm.Scoop kind of spoon 22
Specification is width 4mm, diameter 15mm, 90 degree of angle, and 2-6mm, angle can be set as according to seed physical characteristic by scooping 22 width of kind of spoon
Degree can keep off kind of the length of protrusion 23 and change with the width for scooping kind of spoon 22 depending on the position of the Kong Qun of discharge plate 2.In fact,

Seed exceeds the seed retaining plate 124 of air-suction chamber 111, and seed retaining plate 124 is fixedly connected with shell 1, effectively prevent the seed of seed chamber 121
Directly drawn by adsorption hole 212.
Five regions can be functionally divided by the feed mechanism for seed of the present embodiment known to above-mentioned introduction：As shown in fig. 7, point
The areas Bie Weiyaozhong I, the areas Xi Zhong II, the areas Qing Zhong III, the areas Xie Zhong IV, area V of charging seed are divided according to 360 degree：The areas Yao Zhong I be 173 °~
289 ° of region；The region that the areas Xi Zhong II are 110 °~173 °；The region that the areas Qing Zhong III are 59 °~110 °；The areas Xie Zhong IV are
327 °~59 ° of region area V of charging seed is 289 °~327 ° of region.The areas Yao Zhong I are staggered air-suction chamber 111, areas Xi Zhong II, clear kind
Area III and the areas Xie Zhong IV correspond to air-suction chamber 111, i.e., 111 working range of air-suction chamber includes the areas Xi Zhong II, the areas Qing Zhong III and takes kind
Area IV, area V of charging seed are located at except shell 1.
In use, driving discharge plate 2 rotates, scoops kind of spoon 22 and pass through the areas Yao Zhong I successively, the areas Xi Zhong II, the areas Qing Zhong III, take kind
Area IV and area V of charging seed scoop kind of spoon 22 and start to work from the areas Yao Zhong I, and when scooping kind of spoon 22 by the areas I Yao Zhong, Some seeds can quilt
Gear kind protrusion 23 is blocked to dip seed, stirs kind of an effect with certain while scooping kind, scoops pair of discharge plate 2 during planting
Place is answered to be located in atmospheric pressure；When scooping kind of spoon 22 by the areas II Xi Zhong, the corresponding place of discharge plate 2 is negative into air-suction chamber 111
Pressure area, the negative pressure in air-suction chamber 111 make adsorption hole 212 draw the seed scooped on kind of spoon 22, and ensure that each suction hole is inhaled
The seed of attached essence amount；And scoop the seed that is not adsorbed by adsorption hole 212 on kind of spoon 22 when by the areas III Qing Zhong due to gravity
It is no longer held and is detached from and scoops kind of spoon 22 and fall go back to the lower section of seed chamber 121；When by the areas IV Xie Zhong, the seed meeting in adsorption hole 212
It is lived by negative-pressure adsorption always, the seed of carrying will not be fallen because of the strenuous vibration of feed mechanism for seed；When being adsorbed on adsorption hole 212
Seed through charging seed area V when because corresponding absorption vacancy is except shell 1, the seed in adsorption hole 212 loses negative pressure not
It is adsorbed again, due to falling into V domain of area of charging seed under the double action of centrifugal force and gravity, so far completion scoops-clear kind-of kind-suction kind and takes
It plant-charges seed link.
In the present embodiment, as shown in figure 5, the boundary place for scooping kind of spoon 22 into the areas Yao Zhong I that is located at of shell 1 is provided with confession
Scoop kind of spoon 22 by the first access 122 and alternate path 123, the first access 122 and alternate path 123 be to open up groove type
At entering Yao Zhong areas I from area V of charging seed due to scooping kind of spoon 22, be from the extraneous process entered in shell 1, according to scooping kind of spoon 22
Movement locus passes through to scooping kind of spoon 22 so shell 1 is necessarily required to open up access, ensures that second housing 12 is not interfered and scoops kind of spoon 22
Movement, but open up access occur as soon as leakage kind the phenomenon that.The present embodiment by the way that the first access 122 and alternate path 123 is arranged,
And the size of this two accesses is corresponding with kind of spoon 22 is scooped, that is, scoop gap of kind of the spoon 22 between shell 1 be it is very small, such as
The seed of fruit seed chamber 121 will be revealed, it is necessary to pass through the first access 122 and the second channel twice outpost of the tax office, to effectively prevent
A leakage kind phenomenon.
Road as from the foregoing, the present embodiment have the following advantages：1, kind of the spoon 22 that scoops of the utility model setting has worry in advance
Kind of function is scooped out in seed heap and seed is adsorbed on discharge plate 2 using aspiration principle after appropriate seed, reaches essence amount absorption kind
Son stablizes the purpose of sowing.2, it scoops and is provided with gear kind protrusion 23 on kind of spoon 22, the arranged direction and adsorption hole of gear kind protrusion 23
212 axial direction is parallel, is adsorbed onto on adsorption hole 212 by being refined behind the areas seed arrival Xi Zhong II of 23 blocking of gear kind protrusion, together
When scoop kind of spoon 22 and gear kind of device all has the function of stirring kind, so there is no need to install to stir kind of a device.3, the utility model air-suction chamber 111
Air flue it is shorter, can effectively reduce the loss of suction, therefore the seed adsorbed in the areas Xi Zhong II is stablized, will not be because of dispenser
Strenuous vibration and cause seed the areas Xie Zhong IV slide.4, it in the areas Qing Zhong III, stays in the extra seed scooped on kind of spoon 22 and relies on
Gravity falls on seed chamber 121.5, in the areas Yao Zhong I, although because scoop kind of spoon 22 there are due to lead to second housing 12 not and be it is completely close
Envelope, but can solve after the first access 122 and alternate path 123 are set because second housing 12 non-tight due to showing for leaking kind
As.6, after by finding that increase scoops kind of spoon 22 to the skimulated motion in area V of charging seed, V domain relative narrowness of area of effectively charging seed, together
When V domain of area of charging seed will necessarily be occupied due to the increase in the areas Yao Zhong I, and the various pieces reasonable design of the present embodiment, without mutually dry
Disturb phenomenon.In short, the utility model scoop kind, inhale kind, clear kind, take kind, several links of charging seed are obtained for and are effectively ensured and real
Existing essence amount seeding.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
