(oscillatory sorting device)
Oscillatory sorting device 80 has the screen box 90 of rectangular frame-shaped when overlooking, this screen box 90 is by being configured in crank-type wobble drive portion 89 action of lower rear side and swing, have in this screen box 90: the oscillating plate 91 that the handled thing that the handled thing transfer direction upstream side from threshing chamber 29 leaks down rearward is transferred, the handled thing transferred by this oscillating plate 91 and the handled thing that leaks down from the handled thing transfer direction downstream of threshing chamber 29 are carried out to the top sieve 92 of ragging, refining-sorting is carried out to the handled thing leaked down from top sieve 92 and makes grain (single treatment thing) drain to the lower sieve 93 of the single treatment thing recoverer 82 of below, and the multiple single-wide shakers 94 etc. while the stalk supplied from threshing chamber 29 and top sieve 92 bits are swung transfer towards rear, grain being fallen.
The wobble drive portion 89 oscillatory sorting device 80 being carried out to wobble drive is described.
Wobble drive portion 89 has: the rotating shaft 95 rotated around lateral shaft core P2; There is lateral shaft core relative to rotating shaft 95 core shift and the core shift swinging axle 96 rotated around the axle core of rotating shaft 95; And one end and oscillatory sorting device 80 link and the other end and core shift swinging axle 96 linking part 97 that relatively rotates pivot Zhi Lianjie freely and oscillatory sorting device 80 and core shift swinging axle 96 are linked.
That is, as shown in figure 15, to insert the state of the sidewall 8A of the left and right sides of sheller unit 8 respectively, pair of right and left rotating shaft 95 is rotatably supported with around the same axle core P2 of transverse direction.In addition, the state of the rotating shaft 95 and link that are set up in the left and right sides is integratedly provided with core shift swinging axle 96, and this core shift swinging axle 96 has the lateral shaft core relative to rotating shaft 95 core shift and the axle core around rotating shaft 95 rotates.
And, by the linking part 97 that oscillatory sorting device 80 and core shift swinging axle 96 link, there is the first connecting member 98 being linked to oscillatory sorting device 80 integratedly and the second connecting member 99 being detachably linked to the first connecting member 98 with the state sandwiching core shift swinging axle 96 at the position relative to core shift swinging axle 96 pivot Zhi Lianjie across the state that core shift swinging axle 96 is separated in both sides.
Illustrate if add, then the left and right sides portion of the screen box 90 in self-swinging sorting unit 80 is securing elongated integratedly towards the back lower place is provided with frame support bracket 100.And, the linking part 97 of the left and right sides linked with a pair frame support bracket 100 has the first connecting member 98 and the second connecting member 99 respectively.
First connecting member 98 is formed through in toe lateral and carries out bolted on connection at three positions and be fixedly linked on the tabular linking part 98a of frame support bracket 100, is formed: the recess 98b entered for the bearing 101 being loaded on core shift swinging axle 96 outward in rear portion side; And be positioned at the both sides, front and back of this recess 98b and the flange linking part 98c for linking across core shift swinging axle 96 and the second connecting member 99 via bearing 101.
Second connecting member 99 is formed: the recess 99a entered for bearing 101 and the both sides, front and back that are positioned at this recess 99a flange linking part 99b for linking across core shift swinging axle 96 and the first connecting member 98 via bearing 101.
First connecting member 98 and respective flange linking part 98c, the 99b of the second connecting member 99 are fixed by bolted on connection across core shift swinging axle 96 each other, thus oscillatory sorting device 80 and core shift swinging axle 96 interlock are linked.To discuss below about drive structure, as shown in figure 15, the outward side position of the sidewall 8A of the rotating shaft 95 in the left side in the rotating shaft 95 of the left and right sides has input belt wheel 102, and the power from engine 10 is passed to this input belt wheel 102 and drives rotating shaft 95.If rotating shaft 95 rotates, then core shift swinging axle 96 rotates around the axle core P2 of rotating shaft 95, and the first connecting member 98 and the second connecting member 99 move back and forth up and down integratedly, thus wobble drive oscillatory sorting device 80.In addition, the outward side position of the left and right sidewall 8A on the rotating shaft 95 of the left and right sides, has the counterweight BW for suppressing the body vibration produced along with the driving of oscillatory sorting device 80 respectively.
Then, the supporting construction of the toe lateral of oscillatory sorting device 80 is described.
As shown in Figure 13 and Figure 14, at the position, the left and right sides of the toe lateral of screen box 90, rotatably be there is rolling roller 103 by the state supported around transverse axis core, the sidewall 8A of the left and right sides of sheller unit 8 has pair of right and left and moves guide portion 104, this pair of right and left moves guide portion 104 and is preventing floating and allowing movable while dislocation in the lateral direction of rolling roller 103.
As shown in Figure 14 (a) (d), mobile guide portion 104 has the bottom of blocking rolling roller 103 and the downside guide surface 104a guided and the upside guide surface 104b preventing rolling roller 103 from floating upward that carries out while bearing load rolling, to allow rolling roller 103 to move forward and backward along low early and high after skewed path of navigation.
Oscillatory sorting device 80 is by the movable guiding of the oscillating motion undertaken by wobble drive portion 89 and the rolling roller 103 undertaken by mobile guide portion 104, swing at fore-and-aft direction and above-below direction, thus screen while threshing handled thing is rearward swung transfer.That is, grain drains to below, and dust in small, broken bits, stalk bits etc. are rearward discharged through the dust-exhausting port 105 as the opening being formed in body rear side by sorting wind action.The stalk bits etc. be discharged through dust-exhausting port 105 are fed into straw treating device 12, and then are discharged to outside machine by after cataclasm process finely.
For straw treating device 12, although do not describe in detail its supporting construction, but this straw treating device 12 is rearward rotatably supported around the upper lower shaft core of body transverse width direction end side, by making this straw treating device 12 swing, the rear side of dust-exhausting port 105 can be made to open.
Oscillatory sorting device 80, under the state of link relieving the first connecting member 98 and the second connecting member 99, can plug through the dust-exhausting port 105 of the opening as After-Body side of sheller unit 8.
That is, as shown in Figure 13 and Figure 14, oscillatory sorting device 80 is plugged to the pair of right and left guide rail 106 carrying out sliding guidance freely, the inner face of the sidewall 8A in the left and right sides of sheller unit 8 configures with the state extended along body fore-and-aft direction.As shown in Figure 14 (c), this guide rail 106 has: the vertical facial 106a being fixedly welded on the sidewall 8A of the sheller unit 8 and level face 106b extended inside body transverse width direction from the lower end of this vertical facial 106a, from body fore-and-aft direction, this guide rail 106 is formed as roughly L-shaped.Oscillatory sorting device 80 moves freely directed with the state of the level face being placed in guide rail 106 and supports.
As shown in Figure 13 and Figure 14 (a), the state that the mobile guide portion 104 of the left and right sides is connected with the front end of the guide rail 106 with the left and right sides is located, and the rolling roller 103 supported by mobile guide portion 104 can be made directly to move along guide rail 106.
In each of linking part 97 in the left and right sides, under the state of link relieving the first connecting member 98 and the second connecting member 99, operator props up rear portion side with hand, move at body front and back upward sliding while rolling roller 103 being rolled under the state making the rolling roller 103 of the left and right sides be positioned in the level face 106b of guide rail 106, thus oscillatory sorting device 80 can be plugged from dust-exhausting port 105.
As shown in Figure 14 (c), the left and right outer end position interval L1 each other of pair of right and left guide rail 106, the left and right outer end position interval L2 each other comparing the rolling roller 103 of the left and right sides is formed more largo.In addition, the level face 106b of the guide rail 106 of left and right, the transverse width comparing rolling roller 103 is formed more largo.
Therefore, oscillatory sorting device 80 by be placed in guide rail 106 level face 106b state under make it slide mobile time, there is surplus in the lateral direction, even if oscillatory sorting device 80 becomes the posture tilted a little in the lateral direction sometimes, the worry that rolling roller 103 comes off from guide rail 106 and derails is also few, is easy to carry out slip well mobile.
When oscillatory sorting device 80 moves on guide rail 106, there is surplus in the lateral direction relative to guide rail 106 in oscillatory sorting device 80.By contrast, mobile guide portion 104 is preventing floating and allowing movable parts while dislocation in the lateral direction of rolling roller 103, therefore, following state is become: there is not surplus in the lateral direction and the interval of left and right directions between rolling roller 103 and mobile guide portion 104 is little.
That is, the left and right outer end position interval each other of the rolling roller 103 of the pair of right and left left and right outer end position interval each other of moving guide portion 104 and the left and right sides is roughly the same, becomes the state narrower than the left and right outer end position interval each other of pair of right and left guide rail.
So, as shown in Figure 14 (b), at the connecting portion of guide rail 106 with mobile guide portion 104, be formed with the inclined lead part 107 guided towards mobile guide portion 104 and towards sheller unit 8 inward side by rolling roller 103.By forming inclined lead part 107 like this, when moving to mobile guide portion 104 from guide rail 106, rolling roller 103 is directed towards sheller unit 8 inward side by inclined lead part 107, thus, can move swimmingly under the state can not blocking extension or blocking etc.
As shown in Figure 13 and Figure 15, first connecting member 98 is extended with inclination attitude towards side, the back lower place from the bond sites linked with oscillatory sorting device 80, the divisional plane of the first connecting member 98 and the second connecting member 99 is formed as the toe lateral when body from the side and is positioned at downside and rear portion side is positioned at the low early and high after heeling condition of upside, and the bolt their linked from below side is installed.Therefore, the bond sites of the first connecting member 98 and the second connecting member 99 is to be formed towards the state at body rear.
On the first connecting member 98 linked with screen box 90, the recess 98b of the arc-shaped entered for bearing 101 is formed between the flange linking part 98c of both sides, front and back, under the state not being linked with the second connecting member 99, can be blocked by core shift swinging axle 96 under the state making bearing 101 enter this recess 98b and be supported.That is, the first connecting member 98 is configured to be locked to core shift swinging axle 96 under the state not being linked with the second connecting member 99 and is blocked and is supported.
In the link relieved between oscillatory sorting device 80 and core shift swinging axle 96 or when again making them link, to load from oblique upper relative to bearing 101 by making the recess 98b of the first connecting member 98 and be supported on bearing 101, can by the load of side, core shift swinging axle 96 supporting oscillation sorting unit portion after 80s.That is, with carry out linking compared with the such situation of operation while the load of side, operator's direct supporting oscillation sorting unit portion after 80s, can homework burden be alleviated.
The sheller unit 8 of this combine is in the position higher apart from ground, and oscillatory sorting device 80 is also in the position higher apart from ground in the mounted state.Consequently, when oscillatory sorting device 80 is dismantled foreign side, in intact position, be probably difficult to carry out operation.
So, as shown in figure 13, the toe lateral part 106F that the wobble drive portion 89 that compares of guide rail 106 is positioned at front part of a body side is formed as approximate horizontal posture, low shape after the front height below the rear portion side part 106R that the wobble drive portion 89 that compares of guide rail 106 is positioned at After-Body side is formed as more being located to After-Body side.That is, the rearward end of guide rail 106 is set at the position lower than leading section, by making the rear portion of guide rail 106 be in lower position, thus can carry out taking-up operation like a cork.
As shown in Figure 3, at the upper side position of the top sieve 92 of oscillatory sorting device 80, to be supported on the state of supporting frame 62 accepting net, there is thickness sensor S1 to the top the potentiometer type detected by the thickness of the threshing handled thing transferred being placed in top sieve 92.If the thickness detected by this thickness sensor S1 becomes more than setting value, then lamp is informed in not shown the informing utilizing Drive Section to have.
(lower sieve)
Lower sieve 93 is described.
As shown in figure 16, lower sieve 93 has: be formed much for the rectangle of the sieve aperture of the grain that leaks down crimp wire netting 108, keep the maintenance framework 109 of the surrounding of this crimp wire netting 108 and for keep the left end of framework 109 to link integratedly and the installing plate 110 linked with screen box 90.Installing plate 110 by carrying out bolted on connection at three positions, thus is detachably linked to the side surface part 90a on the left of screen box 90.
As shown in figure 16, the position corresponding with lower sieve 93 of the sidewall 8A on the left of sheller unit 8, is formed with the operation opening 112 covered by opening and closing lid 111 freely.In addition, the position corresponding with lower sieve 93 of the side surface part 90a on the left of screen box 90, is formed with the discrepancy opening 113 can come in and gone out for lower sieve 93, and when installing time sieve 93, this discrepancy opening 113 is mounted plate 110 and blocks.
