In above-described embodiment, according to said structure, whole seeding unit can be divided into successively to I ,Qing Zhong district, Chong Zhong district II ,Dao Zhong district III ,Tui Zhong district's IV and 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, in gas distributing chamber enters circular chamber 29, makes it be full of the malleation air-flow, seed plate 3 combination-type hole 32 places and grain conductor 44 import departments all produce pressure.
2) by the seed inlet 11 of offering on seeding upper shell 1, seed is dropped in Chong Zhong district I from seed inlet 11, under the perturbation action of malleation air-flow and seed plate 3 seed guiding grooves 31, seed is in Chong Zhong district I 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 combination-type hole 32, with seed plate 3, rotates.
3) seed rotates into Qing Zhong district II with seed plate 3, under the effect of gravity, in seed plate 3 seed guiding grooves 31, does not press the seed be attached on combination-type hole 32 can fall back to Chong Zhong district I; Pressure is attached on combination-type hole 32 and can't relies on from flumping the unnecessary seed that recharges kind of district's I and continues to rotate with seed plate 3, when seed passes through seed scraping device 7, under the interruption impact effect that unnecessary seed increases gradually at its moving tooth 72, fall to recharging kind of district's I, thereby guaranteed the simple grain of seeding unit.
4) pressure is attached to single seed on seed plate 3 and enters Dao Zhong district III with the seed plate rotation, under the guiding of ejector blade curved section, leaves the proximal part of seed guiding groove 31.After entering Tui Zhong district IV, seed is under the promotion of ejector blade 6 strip plates 63, along the direction disengaging seed plate 3 of seed guiding groove 31.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, through grain conductor 44, enters grain tube 47, and then is discharged by grain tube 47, completes 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 caused.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 completing 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 are only for illustrating 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; improvement and the equivalents of connection and the structure of indivedual parts being carried out according to the principle of the invention, all should not get rid of in protection scope of the present invention
