Promptly; Because 44 groups in two groups of shelling teeth that close on close on; The shelling handled thing is among 44 groups in two groups of shelling teeth that close on, though the shelling tooth 44 in 44 groups in the shelling tooth of probably leaned forward (conveyance direction upstream side) impacts (catching a packet), the shelling handled thing is among 44 groups in two groups of shelling teeth that close on
(1) impacted by 44 groups in any shelling tooth in front and back.
(2) impacted continuously by 44 groups in the shelling tooth of the shelling tooth 44 of 44 groups in front side shelling tooth and 44 groups in rear side shelling tooth.
(3) knocked simultaneously by former and later two shelling teeth 44 of 44 groups in each shelling tooth of front and back and impact.
Situation in (1), owing to reduced (reducing by half) through the shelling handled thing during the shelling tube total length by the number of times that shelling tooth 44 impacts, the strike that receives also alleviates.
Situation in (2); Because the shelling tooth 44 by front and back impacts continuously; Because the speed of shelling handled thing reduces less when being impacted by the shelling tooth 44 of back; The speed difference of the rotary speed of the rotary speed of shelling tooth 44 and shelling handled thing is less, so the impact when the shelling handled thing is impacted by the shelling tooth 44 at rear obtains relaxing.
Situation in (3) because a shelling handled thing is knocked simultaneously by former and later two shelling teeth 44 and impacts, obtains relaxing so impact.
Therefore, any situation no matter all obtains relaxing as the impact of whole shelling handled thing.That is, even 44 groups in two groups of shelling teeth that front and back are closed on, 44 groups in these paired shelling teeth play a role with the mode that the impact as whole shelling handled thing is relaxed and carry out shelling and handle.
That is, through 44 groups in short two groups of shelling teeth in front and back of spacing, shelling handled thing; Generally speaking; Shelling tooth 44 by the transfer direction upstream side impacts, but when the phenomenon of above-mentioned (1) took place, the shelling handled thing was through the shelling tooth 44 in two groups of paired downstreams; In 44 groups in two groups of shelling teeth that close on next, carry out shelling and handle, receive the number of times that shelling tooth 44 impacts hit and tail off.
The shelling handled thing is among 44 groups in two groups of paired shelling teeth that close on; After being impacted by the shelling tooth 44 of front side (transfer direction upstream side); When and then being impacted (situations of above-mentioned (2)) by the shelling tooth 44 of 44 groups in paired rear shelling tooth; After the strike that receives front side shelling tooth 44, and then catch a packet once more.At this moment, owing to the distance (spacing) of 44 groups in paired two groups of shelling teeth in front and back is approaching than lacking both, the strike of shelling tooth 44 before and after the shelling handled thing receives at short notice continuously.Receive the shelling handled thing after shelling tooth 44 hits, moment, ground was with the speed rotation roughly the same with the rotary speed of shelling tooth.If the shelling handled thing leaves and will generation speed descend from the shelling tooth; If but in the front and back shelling tooth 44 that closes on, catch a packet continuously; Speed during owing in paired back shelling tooth 44, catch a packet reduces less; Impulsive force when in the shelling tooth 44 of back, catching a packet once more is also less, the situation that this impulsive force shortens in the spacing that makes two groups of shelling teeth 44 as a whole, and the summation of two group the impulsive force bigger than spacing is little.
When the shelling handled thing roughly knocks the front and back shelling tooth 44 of 44 groups in two groups of short shelling teeth of paired spacing simultaneously (situations of above-mentioned (3)); Because it is the same to knock with speed with the rotary speed of the rotary speed of any side's shelling tooth 44 in these front and back and shelling handled thing; Promptly can regard a side as and be zero mode and knock, so the impulsive force when roughly side by side being impacted by a pair of shelling tooth 44 probably reduces by half with the speed difference.In addition, when fully side by side being impacted by the shelling tooth of two groups of paired front and back, impulsive force also reduces by half.
As stated,, can suppress the generation of the stem juice of shelling handled thing, generally speaking also alleviate the shelling load because obtain relaxing by the impulsive force of 44 pairs of shelling handled things of shelling tooth.
Large quantity of moisture is contained in the stem of rape seed, if exceedingly impacted time and again consumingly with high speed by the shelling tooth, can get a large amount of stem juice.If the shelling tube is made slimy by stem juice, not only can increase shelling load, and sorting handles and can not carry out well, quality can take place to be reduced.Yet, in this embodiment, through 44 groups in the short two groups of shelling teeth of spacing; The shelling handled thing can receive the shelling effect reliably, simultaneously by as a whole shelling tooth 44 the shelling number of processes is tailed off, or since hitting power as a whole relaxed the generation that makes stem juice and become difficult; And, through with each shelling tooth 44 of 44 groups in the shelling tooth of contiguous set mutually in the configuration of circumferencial direction staggered positions zigzag, reliably the shelling handled thing is handled with any shelling tooth of the different paired front and back shelling tooth crowd of rotatable phase; Meanwhile; When relaxing impulsive force, in front and back shelling tooth crowd's shelling tooth, also carry out the shelling effect easily continuously, when alleviating the shelling load; Can carry out good shelling handles; Meanwhile, can carry out sorting well and handle, reclaim the good grain of quality.
As shown in Figure 3; Send shellings such as bigger stem that dirt mouth 25 discharges and paddy skin to handle to consider to be worth doing from 21 rear ends, shelling chamber; With the shelling bits class of discharging, shred processing by the cutter mill 47 that is configured in dust-exhausting port 32 rear portions as shredding mechanism with rotating blade 45 and fixed blade 46 from the rear end of sorting portion 26.
