That is, the spiral that each threshing tooth 48 is offset while half of position, half of spacing of spacing is equipped on whole thrashing cylinder 16 Shape, thus, in the spinning movement of thrashing cylinder 16, not only to extract straw implement threshing processing, also play will extract straw to Threshing processing direction downstream is the conveying function that rear is sent out.

In addition, by the way that each threshing tub 47 is equipped to change towards and as usual posture and upset posture, because Threshing processing object amount is more and the abrasion of threshing tooth 48 easy to wear, that direction upstream side is handled positioned at threshing it is significant in the case of, , can be quickly by the position for the multiple threshing tooths 48 being had in each threshing tub 47 by changing the direction of each threshing tub 47 Put and change into, the threshing tooth 48 of threshing processing direction upstream side and the threshing of difficult abrasion easy to wear handles the de- of direction downstream The state that grain tooth 48 has been exchanged, thereby, it is possible to which the threshing tooth 48 in less processing direction downstream of wearing and tearing is handled as threshing The more threshing of object amount handles the threshing tooth 48 of direction upstream side and effectively utilized.

Each threshing tooth 48 is constituted by inserting the pole steel in the mounting hole 47A of threshing tub 47, these threshing tooths 48 In the toe lateral for being provided in thrashing cylinder 16, i.e. the threshing tooth 48A of the leading section of threshing processing unit 42, for insert in correspondence Mounting hole 47A in minor diameter part and limit the band stepped-style of large-diameter portion 48b to mounting hole 47A insert, in minor diameter part On be formed with outer screw section 48a for being fixed relative to threshing tub 47, be removably mounted at nut 64 corresponding de- On the assigned position of grain tub 47.

It is provided in the pars intermedia of thrashing cylinder 16, i.e. the threshing tooth 48B of the pars intermedia of threshing processing unit 42 and is formed as a straight line Shape, also, with the state on the center for linking fulcrum 15 and the line at the center of threshing tub 47, be welded and fixed on corresponding On the assigned position of threshing tub 47.

Rearward end, i.e. the threshing tooth 48C of the rearward end of threshing processing unit 42 of thrashing cylinder 16 are provided in, to exist with insert Minor diameter part and the band stepped-style for limiting the large-diameter portion 48b to mounting hole 47A insert in corresponding mounting hole 47A, small The outer screw section 48a for being fixed relative to threshing tub 47 is formed with the portion of footpath, and large-diameter portion 48b is bent to " く " Shape, also, there is the inclined angle of sweep θ b in direction of rotation upstream side towards thrashing cylinder 5 in its protuberance（Reference picture 7）'s Under state, on the assigned position that corresponding threshing tub 47 is removably mounted at nut 64.

That is, each threshing tooth 48A and each threshing tooth 48C positioned at the rear and front end portion of threshing processing unit 42 be it is removable, So being used as the threshing tooth 48 that direction upstream side is handled positioned at threshing（Positioned at multiple threshing tooths of the pars intermedia of threshing processing unit 42 The threshing tooth that direction upstream side is handled by threshing in 48B）Countermeasure during noticeable wear in long-term use, thus it is possible to vary each Multiple positions of threshing tooth 48 are being changed to the threshing tooth that threshing easy to wear handles direction upstream side by the direction of threshing tub 47 In the case of the state that 48 threshing tooths 48 for handling direction downstream with the difficult threshing worn and torn have been exchanged, as long as will be due to each threshing The direction of tub 47 changes and changes on the position opposite with the origin-location for thrashing cylinder 16, rear and front end portion Each threshing tooth 48A and each threshing tooth 48C change, it becomes possible to these threshing tooths 48A, 48C is returned to original position.

In addition, the threshing more than threshing straw quantitative change handles direction downstream, positioned at the threshing tooth of the rearward end of thrashing cylinder 5 48C inhibits the hook of threshing straw due to its angle of sweep θ b presence, so can suppress the threshing due to the hook The delay of straw, can promote the threshing straw（Discharge straw）From the discharge of outlet 23.

As a result, the excellent disposal ability of the raising with achievable threshing performance and threshing efficiency, and for growing Phase ensures that the maintainability aspect of the excellent disposal ability is also fine.

As shown in Fig. 3, Fig. 4 and Fig. 8, notch board 17, with the circumferentially spaced certain intervals of thrashing cylinder 16 on pedestal 65 State before and after towards ground arrangement equipped with the multiple taeniaes 66 being made up of banding steel plate, be with the branch direction of principal axis in thrashing cylinder 16 The state left-right of the spaced up certain intervals in front and back is towards ground arrangement equipped with the banding steel plate by being bent to arc-shaped Multiple 1st horizontal stripes 67 constituted, it is left with the state for separating certain intervals in the longitudinal direction between the 1st adjacent horizontal stripe 67 Right multiple 2nd horizontal stripes 68 constituted towards ground arrangement equipped with the piano wire rod by being bent to arc-shaped, its mesh is formed It is longer than the length on the direction along fore-and-aft direction along the length on the circumferential direction of thrashing cylinder 16 for the rectangle grown crosswise.

That is, by the way that notch board 17 is configured to, its mesh is the rectangle grown crosswise longer on the direction of rotation of thrashing cylinder 16, Easily leaked down by obtained single grain of threshing processing to extracting straw progress etc. from notch board 17, thereby, it is possible to avoid because Single grain from notch board 17 leak down be suppressed and produce decortication grain.

As shown in Figures 3 and 4, in the sheller unit, the power of the gearbox outside figure is via the 1st of V belt translation formula Transmission mechanism 69 passes to the fulcrum 20A of windmill 20, the power from fulcrum 20A via V belt translation formula the 2nd transmission mechanism 70 and the 3rd transmission mechanism 71 of axle driven type pass to the fulcrum 15 of thrashing cylinder 16, and via the 2nd transmission mechanism 70 and with The transmission clutch 72 of compact form is delivered to feeder 13.

In addition, the reference 24 shown in Fig. 3 and Fig. 4 is the top plate that can be opened and closed to be equipped in the top of sheller unit, On its inner surface, have with the state fixed equipment arranged with separating certain intervals in the longitudinal direction with the rotation of thrashing cylinder 16 Act and send dirt valve 49 to the multiple of threshing processing direction downstream guiding by the straw that extracts in threshing chamber 14.Also, also may be used To send dirt valve 49 to be set as adjusting the movable of aperture according to the threshing processing object amount in threshing chamber 14 this, further to realize The raising of threshing performance and threshing efficiency.

As shown in Fig. 4~Fig. 7, Fig. 9, on the outside of the left and right of thrashing cylinder 16, rule are being separated from the rotational trajectory K of threshing tooth 48 Surely on the position being spaced, the bearing support 50,51 of the front and rear direction of net 17 and top plate 24 is accepted equipped with supporting, in these bearing supports 50th, the direction of rotation downstream for being provided in thrashing cylinder 16 in the 51 i.e. bearing support on the right side of thrashing cylinder 16（One of fixed component） On 51, it is equipped with and multiple cuts stalk knife 52.

Stalk knife 52 is respectively cut, with relative to corresponding threshing tooth 48 at the threshing processing direction downstream on bearing support 51 Put 1/4 spacing of skew（=1/4 P）State, the rotational trajectory of corresponding threshing tooth 48 is entered with the outside from threshing tooth 48 Mode between K, is provided on the position for handling direction upstream side by threshing than stalk outlet 18.

According to the structure, it is supplied to from supply mouth 25 in threshing chamber 14 and extracts spinning movement of the straw in thrashing cylinder 16 Effect is lower to be handled by threshing while conveyed on one side, when threshing is transported to by the conveying handling direction downstream, is passed through Hereafter threshing processing, is transported to the upper side of threshing chamber 14, is all pushed against and be cut off cutting on stalk knife 52, while court every time Convey, with stalk outlet 18 is reached, flowed down with the state of chopping from stalk outlet 18 to outlet 23, from outlet to stalk outlet 18 23 are discharged into outside car.

That is, direction downstream is handled in threshing, implements threshing processing and shredded while straw will be extracted with stalk knife 52 is cut, So can prevent from producing because implementing threshing processing in the state of long stalk extract straw to the winding on thrashing cylinder 16 and Mutual winding of long stalk etc., can avoid because this be wound or wrapped around caused by convey the increase of load, and no longer need with The state of long stalk is discharged into the processing of row's stalk after harvesting required when outside car.

Also, direction upstream side is handled in the more threshing of non-threshing straw, straw is extracted without cutting 52 pairs of stalk knife Cut-out, thus can avoid because be attached to extract on straw and easily by the cutting action for cutting stalk knife 52 do not take off grain with The possibility that straw is damaged by the cutting action for cutting stalk knife 52 together is extracted, in addition, handling direction upstream even in threshing Side grain is entered between the straw for turning into block because of mutual winding of long stalk etc., also can handle direction downstream by threshing The cutting action for cutting stalk knife 52 of side and will go into bulk straw between grain take out, can avoid because entering bulk Straw between grain the generation of the 3rd class loss caused outside car is discharged into together with block straw.

And then, by by cut stalk knife 52 be provided in stalk outlet 18 threshing handle direction upstream side, cutting cutting for stalk knife 52 The grain taken out under disconnected effect from block straw leaks down towards sorting mechanism 19 is swung from accepting net 17, thus can avoid because The generation for the 3rd class loss that the grain taken out from block straw is flowed down and caused from stalk outlet 18.

And then, the special chopping dress of chopping processing is carried out due to the discharge straw after handling threshing need not be equipped Put, correspondingly, the simplification of structure and the reduction of cost can be realized, and the lightweight of car body is brought, joint can be realized The mitigation of the overall load of harvester.

As shown in Fig. 4~Fig. 7, Fig. 9, it is the two side by being bent to the steel sheet component 53 of U-shaped respectively to cut stalk knife 52 A pair of 53A is integrally formed over the ground, and the midfeather 53B of steel sheet component 53 is formed as the linking part with the bolt link of bearing support 51, Thus, be individually formed respectively cut stalk knife 52, respectively bolt link on bearing support 51 and constitute situation compared with, can realize Assemble the raising of workability when cutting stalk knife 52.

Each side wall 53A of steel sheet component 53 is formed as, and front and back in the assembled state are looked up in isosceles triangle, Rim portion is waited to turn into the blade part 52a for cutting stalk knife 52 above and below it.

That is, respectively cut stalk knife 52 to be configured to, there is blade part 52a above and below it on two edges, and by spinning upside down ground Change direction to change used blade part 52a, thus, the blade part 52a in use is caused because of abrasion or defect etc. Sharpness reduce in the case of, even if grinding or replacing without cutting stalk knife 52, also can by change cut stalk knife 52 Direction and blade part 52a used in replacing, to tackle simply and at low cost.

As shown in Figure 10, the scalping 31 of roughing is made up of the sorting plate 54 of steel plate, the sorting plate 54, by going out Multiple sorting piece 54A, it is in the inclined squamous upward in the way of more leaning on it to sort direction downstream more by the top to make it, and Arrangement form be located at for the sorting piece 54A of rank rear it is staggered between the sorting piece 54A in prostatitis, and on direction all around with Staggered arrangement form it is multiple leak down mouthful 54B, the sorting plate 54 is more to lean on it to sort direction downstream hind wing more by the top Inclination attitude bolt link is in screen box 29.

That is, the scalping 31 of roughing is constituted with sorting plate 54, thus with to separate the side of certain intervals in the longitudinal direction Formula arrangement is equipped with the multiple gillis being for example made up of banding steel plate（チャフリップ）And constitute situation of scalping 31 etc. and compare, The simplification of structure and the reduction of cost can be realized.

Also, by by multiple sorting piece 54A all around on be arranged in a staggered and to be formed, in Screening Treatment, slightly Sorting process thing on sieve 31 is not to be biased against on one side but be uniformly distributed on left and right directions, so can promote grain from each leakage Lower mouth 54B's leaks down, further, since the hind wing of scalping 31 is tilted, so compared with the situation of scalping 31 is equipped with flat-hand position, In Screening Treatment, the power that sorting process thing is released to the top of sorting process direction upstream side is become big by scalping 31, thereby, it is possible to Suppress sorting process thing to the conveying in sorting direction downstream, and the up and down motion of sorting process thing becomes violent, Neng Gougeng The difference in specific gravity sorting of sorting process thing is effectively carried out, so the 3rd class that grain is discharged into from outlet 23 outside car can be reduced The generation of loss, and the larger grain of proportion leaking down from mouthful 54B that respectively leaks down can be promoted, as a result realize grain and reclaim effect The raising of rate.

Each sorting piece 54Aa of the left and right center side positioned at sorting plate 54 in each sorting piece 54A is formed as overlooking substantially three Angular shape, other each sorting piece 54Ab for being located at left and right ends portion are formed must be shorter than the sorting piece 54Aa of left and right center side, each leakage Lower mouth 54B is formed as identical rectangle.

That is, mouthful 54B that respectively leaks down is formed as bigger than to overlook sorting piece 54Aa, 54Ab that roughly triangular shape etc. goes out Rectangle, thereby, it is possible to promote the leaking down from mouthful 54B that respectively leaks down of sorting plate 54 such as grain, in addition, by by a left side for sorting plate 54 The sorting piece 54Ab at right both ends is formed must be shorter than the sorting piece 54Aa of left and right center side, can promote grain etc. from sorting plate 54 On mouthful 54B that leaks down in left and right ends portion of easy accumulation sorting process thing leak down, as a result, grain can be reduced not from sorting plate The 54 mouthful 54B that respectively leaks down leaks down and the 3rd class loss outside car is discharged into from outlet 23, and can avoid because of sorting plate 54 The reduction of the efficiency of separation caused by sorting process thing accumulation at the portion of left and right ends, so the efficiency of separation and grain can be realized The raising of organic efficiency.

In addition, in the united reaper, due to the direction of rotation of thrashing cylinder 16 is set into positive sight as described above It is dextrorotation when examining, the quantitative change for having sorting process thing to leak down from the right side that net 17 is accepted in the direction of rotation downstream of thrashing cylinder 16 is more Trend.

Therefore, it is being configured to make directly to run down on swing sorting mechanism 19 from the sorting process thing that undertaking net 17 leaks down In the case of, the sorting process thing for being supplied to the right side position for swinging sorting mechanism 19 becomes many, swings the right and left of sorting mechanism 19 The distribution of upward sorting process thing becomes uneven, is easily caused the increase of reduction and the loss of the 3rd class of the efficiency of separation.

So, in the united reaper, as shown in figure 4, the threshing in the direction of rotation downstream positioned at thrashing cylinder 16 On the right side wall 55 of device 5, it is equipped with and the right side of the undertaking net 17 from the direction of rotation downstream positioned at thrashing cylinder 16 is leaked down Sorting process thing guided and make it to the guide plate 56 that flows down of left and right center side for swinging sorting mechanism 19, thus, greatly The sorting process thing that part is leaked down from undertaking net 17 is fed into the left and right center side for swinging sorting mechanism 19, is sorted with swinging The swing of mechanism 19 and evenly distribute in the lateral direction, so can make sorting process thing be not swing sorting mechanism 19 It is biased against on one side but is uniformly distributed on left and right directions, as a result, can avoids because sorting process thing is swinging a left side for sorting mechanism 19 The increase of reduction and the loss of the 3rd class of the efficiency of separation caused on one side is biased against in right direction.

As shown in Figure 1, Figure 2 and shown in Figure 11, in the right-hand end of vehicle body frame 1, it is equipped with and is loaded in car body frame in utilization The assistance platform 57 that the sack-filling device 6 of the right side of frame 1 and carrying out is used during pack operation, it is with the fulcrum 58 of front and rear direction Fulcrum, may be switched to the work posture and the right-hand end along vehicle body frame 1 lodged in the way of being stretched out towards the right outside of car body The storage posture that portion is erected, and work posture is kept by the abutting with vehicle body frame 1, by figure outside setting tool protect Hold to store posture.

In addition, be equipped with sunshade 63 on sack-filling device 6, the sunshade 63 can be to be provided in the upper of the grain box 40 The fulcrum 60 of the front and rear direction of end switches to for fulcrum and covers the operator stepped on to the enterprising luggage bag operation of assistance platform 57 Top effect posture and the storage posture positioned at the top of sheller unit 5, also, by with being provided in grain box 40 1st retainer 61 of the front and rear direction on the right side of upper end abuts to keep work posture, by with being provided in the upper of grain box 40 2nd retainer 62 of the front and rear direction on the left of end abuts to keep storing posture.
