In above-described embodiment, whole seeding unit can be divided into successively according to said structure and fill kind district's I, clearly plant district's II, lead kind of district's III, push away kind of district's IV and an area in preparation V.
Workflow of the present invention is as follows:
1) when work, blower fan by flexible pipe be connected air inlet 11 and be connected, air-flow makes it be full of the malleation air-flow in gas distributing chamber enters circular chamber 29, seed plate 3 combination-type holes, 32 places and grain conductor 44 import departments all produce pressure.
2) seed inlet 11 by offering on the seeding upper shell 1, seed is filled in kind of district's I from seed inlet 11 inputs, under the perturbation action of malleation air-flow and seed plate 3 seed guiding grooves 31, seed is in to fill in kind of district's I and is in floating state, under the pressure-acting of the push effect that is subject to subsequent seed and combination- type hole 32,1～2 seed can be pressed to be attached on the combination-type hole 32, rotates with seed plate 3.
3) seed rotates into seed plate 3 and plants clearly district's II, under action of gravitation, does not press the seed that is attached on the combination-type hole 32 to fall back in seed plate 3 seed guiding grooves 31 and fills kind of district's I; Pressure is attached on the combination-type hole 32 and can't relies on from flumping the unnecessary seed continuation that recharges kind of district's I and rotates with seed plate 3, when seed passes through seed scraping device 7, unnecessary seed is under the interruption impact effect that its moving tooth 72 increases gradually, fall to recharging kind of district's I, thereby guaranteed the simple grain of seeding unit.
4) press and to be attached on the seed plate 3 single seed and to rotate to enter with seed plate and lead kind of district's III, under the guiding of ejector blade curved section, leave the proximal part of seed guiding groove 31.Enter push away kind district's IV after, seed breaks away from seed plate 3 along the direction of seed guiding groove 31 under the promotion of ejector blade 6 strip plates 63.When near grain conductor 44 mouth of pipe, seed breaks away from seed plate 3 just fully, and under the effect of high velocity air, enters grain tube 47 through grain conductor 44, and then is discharged by grain tube 47, finishes the process of charging seed.
5) when seed plate 3 turns to the area in preparation V, the double wedge 84 of seed clearing wheel 8 snaps in the combination-type hole 32 of seed plate 3 and is meshed with seed plate 3, rotate with seed plate 3, can eject the seed of the fragmentation that is stuck in combination-type hole interior 32, avoid because combination-type hole 32 stops up the broadcast leakage that causes.After this, seed plate 3 is rotated further, and carries out next seeding process.
6) rotate the joint 45 of defeated kind of device 4, can realize in actual job, can finishing fast grain tube 47 install and adjusts to being connected and separating of grain conductor 44 and grain tube 47, avoided causing because of this change of grain conductor 44 positions the decline of planting quality.
In above-described embodiment, sealing ring 34 can adopt the anti-attrition self-lubricating materials such as nylon to make.
In above-described embodiment, seed plate 3 can adopt stainless steel material to make.
The various embodiments described above only are used for explanation the present invention; wherein the structure of each parts and connected mode all can change to some extent; all on the basis of technical solution of the present invention; according to improvement and the equivalents that the principle of the invention is carried out connection and the structure of individual component, all should not get rid of in protection scope of the present invention.
