According to the structure of this first technical scheme, for example as shown in figure 18, there is following technical characterictic:
1. when rotating vane 240 is during towards discharge opening 2241, make helical axis 239a around the axis of rotation a of helical axis 239a along by described opening 251 sides and from the downstream of screening portion 226 towards the direction rotation of upstream side, so that after-treatment thing is discharged to the upstream side of screening portion 26; And
2. by surrounding in the communication means 252 of discharge opening 241 to the outside communication means 252a of the upstream side of screening portion 226, be configured in straight line L upper, discharge opening 241 is formed on than the position of the more close screening of straight line L portion 226 sides.This straight line L is the edge of opening 251a and the position that is more positioned at screening portion 226 sides than the outer end of the housing parts 248 of covering rotating vane 240 of the screening portion that is positioned at 226 upstream sides of connection opening 251 in vertical view;
Therefore, after-treatment thing, under the effect of centrifugal force, is discharged to front near the opening 251 with the state of peripheral part that is gathered in housing parts 248 by separating with outside communication means 252a and be communicated with screening portion 226.
The after-treatment thing of discharging from discharge opening thus, can be almost not discharge with the state of outside communication means sliding-contact.In addition, because the spigot surface of outside communication means and the outer end position of discharge opening are also positioned at the position with the more close screening of straight line portion's side (inner side) of the outer end of outlet housing than the front edge of connection opening, therefore, after-treatment thing can be not to be bordering on the angle at right angle and the spigot surface of outside communication means collides yet.Therefore, the situation of the grain husking of after-treatment thing reduces.
According to this first technical scheme, because after-treatment thing can be not agglomerating and with the communication means sliding-contact of described outside or head-on confrontation and fragmentation causes quality to decline, thereby can carry out well threshing.
The second technical scheme of second aspect present invention is to be configured on the basis of the structure of the first technical scheme,
The outer openings edge of described discharge opening is set at than the position of the more close screening of described straight line portion side, and is arranged in than vertical view and connects the edge of opening of described screening portion upstream side of described opening and the position of the straight line more lateral in described helical axis axle center.
According to this second technical scheme, if discharge opening is narrow, not only the discharge of grain becomes difficulty, and the situation that after-treatment thing is sustained damage because of sliding-contact resistance is more, but, can be too narrowless according to the second invention discharge opening, thus after-treatment thing can be discharged to well to the upstream side of screening portion.
The 3rd technical scheme of second aspect present invention is to be configured on the basis of the structure of the first or second technical scheme,
The inner side edge of opening of described discharge opening is set in than the position of the sidewall more lateral of described threshing portion.
According to the 3rd technical scheme, if cover rotating vane and there is the housing parts of discharge opening with state configuration inside and outside the sidewall across threshing portion, opening processing, the loopback of after-treatment thing of side plate of threshing portion being carried out raised and sent the installation exercise process of device to become complicated, but, make and become easy according to the 3rd technical scheme.

As shown in Figure 4, the supply port 30 of threshing portion 22 is formed as between the antetheca 66 of lower tank 20 and the antetheca 36 of upper tank 21, with roughly along the roughly circular arc of accepting net 29 from these antethecas 66, the left part 66A of the end of conduct clamping conveying mechanism side in 36,36A, recessed to the right side wall 67 of lower tank 20 of opposition side that is positioned at clamping conveying mechanism 26.In addition, by the shape of supply port 30 being set as to be positioned at the right one end side portion 30a reduction of leaving clamping conveying mechanism 26 1 sides in edge 30A thereon, make its lower limb 30B can not be positioned at the position more on the lower than the surperficial 29A that accepts net 29, and, can not be positioned at than accepting net 29 more by body right side away from right-hand member edge 30C farthest of clamping conveying mechanism 26, so that the fringe tip side of harvesting straw is from supply port 30 successfully at thrashing cylinder 28 with accept between net 29 and move.
In addition, as previously mentioned, if harvesting delivery section 3 is configured to two frame four lines harvesting modes, in the time of harvesting three row or four lines crops, acting on the holding up in standing grain framework 17 of two row crops, the grain lifter 13 of holding up standing grain framework 17 by being arranged on this, is positioned at the distolateral crops straw in body left and right than the crops straw that is positioned at body left and right center side, is taken off significantly the left and right center side to body.Therefore, it is higher than the crops straw of left and right center side that the distolateral crops straw in left and right is sheared the position that device 14 shears, thereby harvested length shortens.Its result, gathered in straw generally for what carried to sheller unit 4 by harvesting delivery section 3, the length of fringe tip side as band grain portion is elongated, therefore, be necessary that the length that threshing processing is set as to the fringe tip side that makes the harvesting straw that is supplied to threshing portion 22 inside is longer than the dark threshing processing of normal length.
Like this, as mentioned above, the threshing degree of depth in the time that threshing is processed is set in corresponding to processing than common threshing the dark threshing processing of two darker frame four lines harvesting modes, if the outlet of threshing portion 22 31 is formed as, for example make the height and position of right one end side portion in its top edge, position in the body left and right directions at its right-hand member edge is identical with supply port 30 or roughly the same, in the case of mobile thrashing cylinder 28 and accept between net 29 by the fringe tip side (the fringe tip side of stalk) of harvesting straw with the circular-arc attitude along accepting net 29 from thrashing cylinder 28 with accepting and passing through between net 29, its fringe tip side end easily hangs over the top edge of outlet 31, in addition, in the case of from thrashing cylinder 28 and accept between net 29 by because deadweight is from the circular-arc pose recovery along accepting net 29 to laterally toppling over attitude, its fringe tip side end easily hangs on the right-hand member edge of outlet 31.
So, as shown in Figure 5, in this sheller unit 4, the right one end side portion 31a that leaves clamping conveying mechanism 26 1 sides in the top edge 31A of the outlet of threshing portion 22 31 is set as being made up of the right part 37a of the lower limb 68A of top rear wall 68 of lower tank 20 and the lower limb 37A of the rear wall 37 of upper tank, and this lower tank 20 is formed the top of the right one end side portion 30a of the top edge 30A that is positioned at supply port 30.In addition, using perpendicular attitude, the right side wall of the lower tank of the right side wall as threshing portion 22 20 67 is uprightly arranged on than accepting net 29 more by the right lateral position of body, is formed the right-hand member edge 31B of outlet 31 by the inner surface 67A of this right side wall 67.
By top edge 31A and the right-hand member edge 31B of such formation outlet 31, in the top edge 31A of outlet 31 height and position of the height and position of right one end side portion 31a right one end side portion 30a in the top edge 30A of supply port 30 above, and the right-hand member edge 31B of outlet 31 is positioned at than accepting the position of net 29 further from clamping conveying mechanism 26 on body left and right directions.
, because being positioned at by the opening shape of the right part of the fringe tip front of harvesting straw of outlet 31 becomes to the state of upside and right side expansion, therefore, even at thrashing cylinder 28 and accept between net 29, move and come by the fringe tip side (the fringe tip side of stalk) of harvesting straw, with the circular-arc attitude along accepting net 29 from thrashing cylinder 28 with accept between net 29 and pass through, its fringe tip side end is also difficult to hang on the top edge 31A of outlet 31, in addition, even from thrashing cylinder 28 with accept when passing through between net 29 because deadweight is from the circular-arc pose recovery along accepting net 29 to laterally toppling over attitude, its fringe tip side end also can not hang on the right-hand member edge 31B of outlet 31.
Its result, effectively suppress due to the fringe tip side end of stalk hang over the top edge 31A of outlet 31 or right-hand member edge 31B upper and in the phenomenon of the periphery generation straw blockage of outlet 31.
As shown in Fig. 5, Fig. 6 and Fig. 8～Figure 11, to guide from thrashing cylinder 28 and accept the guide plate 69 of the stalk fringe tip side end passing through between net 29, with more offside in the attitude tilting towards right back (backward expansion) of body rear side, be arranged on the right side wall 67 of lower tank 20 across the right one end side portion 39a of rearward end 39A of supporting frame 39 and the right-hand member edge 31B of outlet 31.
That is, when by thrashing cylinder 28 and the fringe tip side of accepting the stalk between net 29 because of deadweight from the circular-arc pose recovery along accepting net 29 when laterally toppling over attitude, guide plate 69 stops this fringe tip side end and guides to lower right side gradually.
Thus, can effectively suppress because the fringe tip side of stalk returns to suddenly and laterally topples over attitude and fracture at this fringe tip side generation stalk from circular-arc attitude, and thus in the phenomenon of outlet 31 periphery generation straw blockages.
As shown in Fig. 5, Fig. 6 and Fig. 8～Figure 12, three limit rods 70 are separated to predetermined distance and are equipped on rearward end 39A at left and right directions towards the attitude of body right lateral side with the rearward end 39A from supporting frame 39, the situation that the handled thing that these three limit rods 70 flow down towards swinging sieving machine structure 40 the rearward end 39A from supporting frame 39 is offset to the right side of the swinging sieving machine structure 40 as its direction of rotation downstream due to the rotation of thrashing cylinder 28 limits.
; by the effect of each limit rod 70; can make the handled thing of the rearward end 39A (accepting the rear end of net 29) from supporting frame 39 flow down equably along left and right directions towards swinging sieving machine structure 40; thus; can carry out wind screening, sieve screening for the handled thing flowing down from the rearward end 39A of supporting frame 39 well, can seek to improve screening efficiency and screening precision.
As shown in Figure 6 and Figure 7, stalk clamping conveying mechanism 51 is configured to, and the driving delivery section 71 with ring-type swivel-chain 54 grades with projection can be the displacement that swings up and down of the guide post 53 of fulcrum with respect to the driving shaft 72 taking its rear portion.In addition, across drive delivery section 71 front and back pars intermedia and be positioned at threshing portion 22 upper rear end fixed frame 73 and set up extension spring 74, this extension spring 74 to drive delivery section 71 apply along ascent direction swing power.Uprightly be provided with bracket 75 and attaching parts 76 at the leading section that drives delivery section 71.On bracket 75, be formed with slotted hole 75A, limit with steady pin 77 butts that are arranged on fixed frame 73 scope that swings up and down that drives delivery section 71 by this slotted hole 75A.Along with the swinging operation of upper tank 21 from open position to closed position, attaching parts 76 are pressed downwards with upper frame 78 butts of upper tank 21.Press by this, drive delivery section 71 to overcome the effect of extension spring 74, drop to from the maintenance position swing of leaving guide post 53 the clamping transfer position that approaches guide post 53.
; under the open state of the thrashing cylinder that upper tank 21 is swung to open position from closed position; owing to also can making to drive delivery section 71 to be in the open state that is positioned at maintenance position in stalk clamping conveying mechanism 51; therefore, can together carry out the maintenance of stalk clamping conveying mechanism 51 with thrashing cylinder 28, the maintenance of accepting net 29 etc.
As shown in Fig. 7 and Figure 13, in guide post 53, the position in front of fixed guide 58 rearward end, support 58A forms opening 58B down, and the leaf spring 79 that snaps in co-end 79A is installed in this opening 58B.On the other hand, the rearward end 59A of movable guider 59 is bent downwardly.In addition, along the direction vertical with the glide direction of movable guider 59, on the lower limb of the rear end side of movable guider 59, form a slot part 59B, or form along fore-and-aft direction three slot part 59C separated by a distance on the lower limb of its leading section.
Thus, make movable guider 59 carry out slide by controlling the rearward end 59A of movable guider 59, if any slot part 59B of movable guider 59,59C is relative with the opening 58B of fixed guide 58, under the effect of leaf spring 79, can make movable guider 59 be fixed on this any slot part 59B, the opening 58B of 59C and fixed guide 58 relative to operating position.In addition, make the slot part 59B of movable guider 59 postmedian sides relative with the opening 58B of fixed guide 58 to state as the supply condition of guide post, make any slot part 59C of movable guider 59 middle front part sides relative with the opening 58B of fixed guide 58 to state as the non-supply condition of guide post 53.,, under the non-supply condition of guide post 53, can make the extending length of movable guider 59 change with three phases.
In addition, because movable guider 59 is at its each slot part 59B, the section shape of the formation position of 59C is D shape roughly, therefore, snap onto this any slot part 59B at the co-end of leaf spring 79 79A, under the stationary state in 59C, the rearward end 59A that controls movable guider 59 makes movable guider 59 carry out rotating operation around its axis, can easily make the co-end 79A of leaf spring 79 from this any slot part 59B, 59C departs from, and can carry out the slide of movable guider 59.
, can easily by the operation of movable guider 59, guide post 53 be switched between supply condition and non-supply condition.
