As a result, have the good disposal ability of the raising that can realize threshing performance and threshing efficiency, and also fine aspect the maintainability of the disposal ability that is used for guaranteeing that for a long time this is good.

As Fig. 3, Fig. 4 and shown in Figure 8, notch board 17, the a plurality of taeniaes 66 that constitute by banded steel plate are equipped with on pedestal 65, upwards to separate in the week at threshing tube 16 before and after the state of certain intervals to arrange towards ground, with the direction of principal axis at threshing tube 16 is to separate on the fore-and-aft direction about the state of certain intervals to arrange towards ground to be equipped with a plurality of the 1st horizontal stripes 67 that constitute for circular-arc banded steel plate by being bent to form, between the 1st adjacent horizontal stripe 67, so that arrangement is equipped with a plurality of the 2nd horizontal stripes 68 that constitute for circular-arc piano wire rod by being bent to form towards ground about the state that separates certain intervals on the fore-and-aft direction, its mesh forms the rectangle of growing crosswise, and the length on the circumferential direction of threshing tube 16 is longer than the length on the direction of fore-and-aft direction.

Promptly; by notch board 17 is constituted; its mesh is the rectangle of growing crosswise long on the direction of rotation of threshing tube 16; by handling the simple grain grain that obtains etc. and leak down from notch board 17 easily to extracting threshing that straw carries out; thus, can avoid leaking down to be suppressed the decortication grain that produces from notch board 17 because of simple grain grain.

As shown in Figures 3 and 4, in this sheller unit, pass to the fulcrum 20A of windmill 20 via the 1st transmission mechanism 69 of band driven type from the power of the outer gearbox of figure, pass to the fulcrum 15 of threshing tube 16 from the power of this fulcrum 20A via the 3rd transmission mechanism 71 of the 2nd transmission mechanism 70 of band driven type and through-drive formula, and be delivered to feeder 13 via the transmission clutch 72 of the 2nd transmission mechanism 70 and band tension type.

In addition, Fig. 3 and Reference numeral 24 shown in Figure 4 are the top boards that can be equipped in the top of sheller unit with opening and closing, on the surface, have along with the spinning movement of threshing tube 16 straw is handled a plurality of dirt valves 49 that send from the guiding of direction downstream to threshing that extract in the threshing chamber 14 within it on fore-and-aft direction, to separate the state fixed equipment of arranging on certain intervals ground.And, also this can be sent dirt valve 49 to be set as and regulate the movable of aperture according to the threshing handled thing amount in the threshing chamber 14, further realize the raising of threshing performance and threshing efficiency.

As Fig. 4～Fig. 7, shown in Figure 9, the outside about threshing tube 16, separate on the position of predetermined distance at rotational trajectory K from threshing tooth 48, be equipped with the front and back of accepting net 17 and top board 24 towards bearing support 50,51, the direction of rotation downstream that is provided in threshing tube 16 in these bearing supports 50,51 is on the bearing support (example of fixed part) 51 on threshing tube 16 right sides, is equipped with a plurality of stalk cuttves 52 of cutting.

Respectively cut stalk cutter 52, threshing on bearing support 51 is handled the direction downstream and is sentenced threshing tooth 48 positions with respect to correspondence and be offset 1/4 spacing (=1/4P) state, enter into the mode between the rotational trajectory K of corresponding threshing tooth 48 with the outside, be provided to than row's stalk mouth 18 and handle on the position of direction upstream side by threshing from threshing tooth 48.

According to this structure, the straw that extracts that supplies in the threshing chamber 14 from supply port 25 is transferred while being subjected to the threshing processing under the effect of the spinning movement of threshing tube 16, when being transported to threshing processing direction downstream by this conveying, handle by threshing after this, be transported to the upper side of threshing chamber 14 at every turn, all be pushed to be against and cut on the stalk cutter 52 and be cut off, carry towards row's stalk mouth 18 simultaneously, along with the row's of arrival stalk mouth 18, state with chopping flows down to outlet 23 from row's stalk mouth 18, is discharged into outside the car from outlet 23.

Promptly, handle the direction downstream in threshing, to extract straw with cutting 52 choppings of stalk cutter while implementing the threshing processing, so can prevent because of handling extracting the coiling of straw on threshing tube 16, reaching long stalk winding each other etc. of producing implementing threshing under the state of long stalk, can avoid the increase of the conveying load that causes because of this coiling or winding, and no longer need be discharged into the state of long stalk car when outer the required post-job row's stalk of harvesting handle.

And, handle the direction upstream side in the threshing that threshing straw not is more, do not cut 52 pairs of cut-outs that extract straw of stalk cutter, so can avoid because of being subjected to cutting the possibility that the cutting action of stalk cutter 52 damages with extracting straw attached to the grain of not taking off that extracts the cutting action that is subjected to cutting stalk cutter 52 on the straw easily, in addition, even handling direction upstream side grain in threshing enters into because of long stalk winding each other etc. and becomes between the straw of bulk, also can handle the cutting action of cutting stalk cutter 52 in direction downstream and the grain that will enter between the block straw takes out, can avoid being discharged into the generation that outer the 3rd class that causes of car is lost with the straw of bulk because of the grain that enters between the block straw by threshing.

And then, handle the direction upstream side by the threshing that will cut stalk cutter 52 row's of being provided in stalk mouths 18, the grain that takes out from the straw of bulk under the cutting action of cutting stalk cutter 52 leaks down towards swing sorting mechanism 19 from accepting net 17, so can avoid flowing down from row's stalk mouth 18 because of the grain that takes out from the straw of bulk the generation of the 3rd class loss that causes.

And then, because the discharge straw that does not need to equip after the threshing processing is shredded the shredding mechanism of the special use of processing, correspondingly, the simplification that can implementation structure and the reduction of cost, and the alleviating of lightweight load that bring, combine integral body that can realize car body.

As Fig. 4～Fig. 7, shown in Figure 9, respectively cut stalk cutter 52 and be by the two side 53A that is bent to form to the steel sheet component 53 of コ word shape a pair of integrally formed over the ground, the midfeather 53B of steel sheet component 53 forms the linking part that links with bearing support 51 bolts, thus, with independent form respectively cut stalk cutter 52, bolt is attached on the bearing support 51 and situation about constituting is compared respectively, can realize assembling the raising of the operation when cutting stalk cutter 52.

Each sidewall 53A of steel sheet component 53 forms, and observes to be isosceles triangle on the fore-and-aft direction under the assembled state, and its equilateral part up and down becomes the blade part 52a that cuts stalk cutter 52.

Promptly, respectively cutting stalk cutter 52 constitutes, has blade part 52a in the two edge portions down thereon, and by changing towards changing employed blade part 52a with spinning upside down, thus, under the situation that sharpness because of wearing and tearing or the blade part 52a in causing using such as damaged has reduced, even do not cut the grinding or the replacing of stalk cutter 52, also can by change cut stalk cutter 52 towards replacing employed blade part 52a, come simply and at low cost the reply.

As shown in figure 10, the scalping 31 of roughly selecting usefulness is made of the sorting plate 54 of steel plate system, described sorting plate 54, by going out a plurality of minutes chip select 54A, make it be the squamous up of leaning on the mode of top to tilt more by its sorting direction downstream with more, and arrange branch chip select 54A staggered between the branch chip select 54A in prostatitis form rank rear, and forming a plurality of mouthful 54B of leaking down with staggered arrangement on the direction all around, this sorting plate 54 is to lean on the inclination attitude bolt of the hind wing of top to be attached in the screen box 29 more by its sorting direction downstream more.

Promptly, constitute the scalping 31 of roughly selecting usefulness with sorting plate 54, compare the simplification that can implementation structure and the reduction of cost so constitute the situation etc. of scalping 31 with arrange a plurality of gillis (チ ヤ Off リ Star プ) that outfit for example is made of banded steel plate in the mode that on fore-and-aft direction, separates certain intervals.

And; by being gone up all around with staggered arrangement, a plurality of minutes chip select 54A form; in Screening Treatment; sorting process thing in the scalping 31 is not to lean on partially on one side on the left and right directions but distribution equably; so can promote grain leaking down from mouthful 54B that respectively leaks down; in addition; because scalping 31 hind wings tilt; so compare with the situation of equipping scalping 31 with flat-hand position; in Screening Treatment; scalping 31 is released power from the sorting process thing to the top of sorting process direction upstream side becomes big; thus; can suppress of the conveying of sorting process thing to sorting direction downstream; and moving up and down of sorting process thing becomes violent, can more effectively carry out the difference in specific gravity sorting of sorting process thing, is discharged into the generation that the 3rd class outside the car is lost so can reduce grain from outlet 23; and can promote the bigger grain of proportion from the leaking down of mouthful 54B that respectively leaks down, the result has realized the raising of grain organic efficiency.

Each minute chip select 54Aa of the left and right sides center side that is positioned at sorting plate 54 among each minute chip select 54A forms and overlooks the general triangular shape, other each minute chip select 54Ab that are positioned at both ends, the left and right sides form shortlyer than the branch chip select 54Aa of left and right sides center side, and mouthful 54B that respectively leaks down forms identical rectangle.

Promptly; mouthful 54B that respectively leaks down is formed than to overlook the branch chip select 54Aa that general triangular shape etc. is gone out; the rectangle that 54Ab is big; thus; can promote leaking down from mouthful 54B that respectively leaks down of sorting plate 54 such as grain; in addition; form shortlyer by branch chip select 54Ab than the branch chip select 54Aa of left and right sides center side with the both ends, the left and right sides of sorting plate 54; can promote mouthful 54B that leaks down at the both ends, the left and right sides of the easy accumulation sorting process thing from the sorting plate 54 such as grain to leak down; the result; can reduce grain does not leak down and is discharged into the 3rd class loss outside the car from outlet 23 from mouthful 54B that respectively leaks down of sorting plate 54; and can avoid piling up the reduction of the efficiency of separation that causes, so can realize the raising of the efficiency of separation and grain organic efficiency because of the sorting process thing that the both ends, the left and right sides of sorting plate 54 are located.

In addition, in this combine, owing to be dextrorotation when setting the direction of rotation of threshing tube 16 for top view as described above, the trend that the quantitative change of leaking down in the right side that has the sorting process thing promptly to accept net 17 from the direction of rotation downstream of threshing tube 16 is many.

Therefore, directly run down under the situation on the swing sorting mechanism 19 constituting to make from accepting sorting process thing that net 17 leaks down, the sorting process thing that supplies to the position, right side of swing sorting mechanism 19 becomes many, the distribution of the sorting process thing on the left and right directions of swing sorting mechanism 19 becomes inhomogeneous, causes the reduction of the efficiency of separation and the increase of the 3rd class loss easily.
