And, when the spinning movement of thrashing cylinder 16, the most multiple threshing tooths 48, even the threshing processing component that the six roots of sensation thrashing cylinder framework 47 forming the threshing process portion 42 of thrashing cylinder 16 also serves as acting on processed material works, thus, it is possible to realize the raising of threshing performance and threshing efficiency.

And, owing to a large amount of grain are leaked down from undertaking net 17 after simple grain by the threshing process of thrashing cylinder 16 toe lateral, the processed material amount of pars intermedia before and after thrashing cylinder 16 is reduced, pars intermedia before and after this, the second plate 45 separated before and after the internal space S of thrashing cylinder 16 stop the processed material in the internal space S of thrashing cylinder 16 process the flowing of downstream, direction towards threshing, rotating by processed material guide threshing cylinder 16 around in company with thrashing cylinder 16, thus promote by threshing tooth 48 grade to the strike of processed material or comb into etc. and the threshing that carries out, and simple grain grain is from accepting leaking down of net 17.Thus; the generation lost can be stoped three times, these three times losses result from simple grain grain contained in processed material or non-threshing straw etc. do not stop by the internal space S of thrashing cylinder 16, together do not discharged from the row's stalk mouth 18 being formed at threshing and processing direction end of downstream side in company with threshing straw.

And then, when the spinning movement of thrashing cylinder 16, attract, from supply mouth 25, the extraneous gas of coming with rotating of helical blade 43 together with the harvesting straw being grilled into conveying under the effect being grilled into portion 41, flow swimmingly around thrashing cylinder 16 or in the internal space S in threshing process portion 42.Flow out to feeder 13 from supply mouth 25 thereby, it is possible to prevent being processed the stalk bits etc. produced by threshing, and can more be quickly carried out the processed material conveying towards threshing process downstream, direction.

In addition, inside from the extraneous gas of the supply mouth 25 attraction feeder 13 by being connected with supply mouth 25, and, this feeder 13 will be formed in being equipped with shut-off mechanism 11 and connects with supply mouth 25 with the delivery outlet (not shown) reclaiming straw output on the harvesting recoverer of the harvesting conveyer device 4 of auger conveyor 12 grade, thus, when thrashing cylinder 16 spinning movement, under helical blade 43 rotates the sucking action produced, the dust such as the stalk bits being processed by harvesting in harvesting recoverer or recycling and produce are also in company with extraneous gas together, it is flowed into surrounding or the internal space S in threshing process portion 42 of thrashing cylinder 16 via inner space and the supply mouth 25 of feeder 13 from the delivery outlet of harvesting recoverer.Itself as a result, it is possible in suppression harvesting recoverer the attachment of stalk bits etc. pile up or fly upward, it is possible to suppress because of this attachment that to pile up the conveying of the harvesting straw caused bad and because this flies upward the reduction etc. of working environment and the visibility caused.

Each plate 44 ~ 46 is in the circle centered by fulcrum 15, and the bolt on the equidistant position of fulcrum 15 at its outer circumferential side connects thrashing cylinder framework 47.It is to say, at the outer circumferential side of each plate 44 ~ 46, be equipped with six roots of sensation thrashing cylinder framework 47 according to the state separating certain intervals arrangement in its circumferential direction, the cylinder diameter of thrashing cylinder 16 increases.Thereby, it is possible to prevent the winding gathering in straw relative to thrashing cylinder 16.

Each thrashing cylinder framework 47 is bolted on each plate 44 ~ 46, can change towards and upset posture in opposite direction before and after becoming its fore-and-aft direction usual posture consistent with direction before and after thrashing cylinder 16 and its fore-and-aft direction and thrashing cylinder 16, and adjacent thrashing cylinder 47 each other before and after towards on the contrary.

On each thrashing cylinder framework 47, it is equipped with multiple installing hole 47A, the 47B that can install threshing tooth 48, they on its fore-and-aft direction with the state of a determining deviation P arrangement, and distance L2 at the center of distance L1 at the center in the installing hole 47A from the front end of thrashing cylinder framework 47 to forefront and the installing hole 47A from the rear end of thrashing cylinder framework 47 to rearmost has the state of difference of half pitch (=1/2P).

Further, each thrashing cylinder framework 47 with adjacent framework each other before and after connect towards contrary state and to be bearing on each plate 44 ~ 46.Thus, while use the framework of identical composition as six thrashing cylinder frameworks 47, it is possible to position, in the state of fore-and-aft direction dislocation half pitch, the threshing tooth 48 equipped on these thrashing cylinder frameworks 47 with the threshing tooth 48 of adjacent thrashing cylinder framework 47.Its result, need not reduce the interval of adjacent threshing tooth 48, just can reduce threshing tooth 48 and be spaced the strike of processed material.

That is, cost cutting is achieved by each thrashing cylinder framework 47 is set to identical composition, and, the least straw the most incidental, that result from processed material in interval that effectively prevent adjacent threshing tooth 48 blocks relative to the processed material of the winding of threshing tooth 48, meanwhile, it is capable to the cycle of processed material is improved threshing performance by increasing threshing tooth 48.

And, by each thrashing cylinder framework 47 is equipped to can by towards be changed as usual posture and upset posture, during life-time service, significant occasion is more become in the abrasion being positioned at the threshing tooth 48 processing direction upstream side because of the threshing many and more easy to wear of processed material amount, by change each thrashing cylinder framework 47 become threshing more easy to wear to process the threshing tooth 48 of direction upstream side towards, it is possible to the position change of the multiple threshing tooths 48 possessed by each thrashing cylinder framework 47 at one stroke and nonabradable threshing processes the state that the threshing tooth 48 in downstream, direction exchanges.Thereby, it is possible to the threshing tooth 48 that the threshing tooth 48 that threshing few for abrasion processes downstream, direction processes direction upstream side as the threshing that processed material amount is many is effectively utilized.

Four (the most each two) the installing hole 47A at both ends before and after each thrashing cylinder framework 47 that are positioned in multiple installing hole 47A, 47B are formed as than little for the installing hole 47B diameter being positioned at pars intermedia.

It addition, between the end and the lower edge respectively sending dirt valve 49 of each threshing tooth 48, be set with little gap to make to send dirt valve 49 processed material to be guided good.And, between the end and the inner surface accepting net 17 of each threshing tooth 48, in order to promote that simple grain grain leaks down from accepting net 17, it is set with than be set in the gap that the gap between end and the lower edge respectively sending dirt valve 49 of each threshing tooth 48 is big.

Such as Fig. 3, Fig. 4, Fig. 6 ~ 8 and as shown in Figure 10, in thrashing cylinder 16, on the outer peripheral face that it is grilled into portion 41, spirally welding has two support plate 41A.Further, on the back side of these support plates 41A, bolt connects the helical blade 43 having correspondence dismantledly, and presenting their the outer edge side outer rim than corresponding support plate 41A also will side is prominent outward state.

That is, in this thrashing cylinder 16, the harvesting straw being delivered to supply mouth 25 by feeder 13 supply is grilled into conveying along with the rotation of thrashing cylinder towards rear, thus two helical blades 43 contact with harvesting straw fierceness and are susceptible to result from the abrasion of this contact, these two helical blades 43 are equipped in the portion that is grilled into 41 of thrashing cylinder 16 dismantledly, thus, the occasion of each helical blade 43 noticeable wear is being made by long-term use, it is possible to the most only helical blade 43 is replaced.Its result, be not result in such as by this helical blade 43 welding the most dismantledly the occasion being grilled in portion 41 like that will together with the helical blade 43 of abrasion replace the portion of being grilled into 41 trouble or economic aspect unfavorable, it is possible to suitably carry out the disposal of abrasion for helical blade 43.

Strengthened with multiple ribs 41B of the outer peripheral face ground welding being grilled into portion 41 it addition, each support plate 41A utilizes across their front surface.

Such as Fig. 3, Fig. 4, Fig. 6, Figure 13 and as shown in Figure 14, in sheller unit 5, equipped with conveying assisted guides 51 between its antetheca 26 and undertaking net 17, this conveying assisted guides 51 accepts the harvesting straw being delivered to supply mouth 25 by feeder 13 supply, and assist the harvesting straw carried out by two helical blades 43 is grilled into conveying.Conveying assisted guides 51 is constituted by covering pair of right and left guide member 51A, 51B that be grilled into the lower side in portion 41, that bolt connects into when facing viewing in substantially U-shaped from below.Guide member 51A, 51B of left and right are consisted of following manner, i.e., before and after being bolted to dismantledly on the first plate 51a of the stainless steel on the pair of right and left supporting frame 52 on the top of the antetheca 26 and sheller unit 5 that are provided to sheller unit 5, welding forms the second plate 51b from the antetheca 26 of sheller unit 5 to the stainless steel of the guide surface accepting net 17.

That is, in this sheller unit 5, owing to the conveying that is grilled into of the harvesting straw carried out by two helical blades 43 is assisted, conveying assisted guides 51 contacts with harvesting straw fierceness, and then it is susceptible to the abrasion produced because of this contact, being equipped to by conveying assisted guides 51 can the form of mounting or dismounting, and, by consist of can left and right segmentation left and right two segmenting structure, i.e., the guide member 51B on the right side in the guide member 51A being positioned at the left side of the direction of rotation upstream side of thrashing cylinder 16 and the direction of rotation downstream being positioned at thrashing cylinder 16, thus, making to carry the occasion of the overall noticeable wear of assisted guides 51 because of life-time service, can the most only change conveying assisted guides 53.It addition, making to carry the occasion of left and right any one guide member 51A, 51B noticeable wear in assisted guides 51 because of life-time service, it is possible to only significant for abrasion guide member 51A, 51B are replaced.Its result, even if being not result in such as trouble or economic aspect unfavorable as conveying assisted guides 51 welding the most dismantledly occasion on the supporting frame 52 etc. accepting net 17 and left and right being replaced together with conveying assisted guides 51 like that and accepting net 17 or left and right supporting frame 52 or also to change whole conveying assisted guides 51 during as any side, left and right noticeable wear of the inseparable occasion conveying assisted guides 51 like that ceding territory to constitute conveying assisted guides 51, it is possible to suitably carry out the disposal of abrasion for conveying assisted guides 51.

Being additionally, since conveying assisted guides 51 is the high-strength stainless steel parts that corrosion resistance is strong, it is possible to reduce the replacing frequency caused because of abrasion.

Such as Fig. 3, Fig. 5, Fig. 6 and as shown in Figure 15, accepting net 17 and be made up of four the undertaking net means 53 being formed as same shape, bolt is connected to the supporting frame 52 of left and right dismantledly.In each undertaking net means 53, equipped with the base frame 53A that skeleton construction is rectangular.In the frame of base frame 53A, according to the state of the circumferentially spaced certain intervals at thrashing cylinder 16, front and back to ground, arrangement is equipped with the multiple taeniae 53B being made up of banding steel plate.And, according to the state of the spaced up certain intervals in side before and after as 16 direction of principal axis of thrashing cylinder, to ground, arrangement is equipped with the multiple first horizontal stripe 53C being made up of the banding steel plate being bent to arc-shaped in left and right.And then, between the first adjacent horizontal stripe 53C, according to separating the state of certain intervals in the longitudinal direction, to ground, arrangement is equipped with the multiple second horizontal stripe 53D being made up of the piano wire rod being bent to arc-shaped in left and right.Further, the configuration space of each bar 53B ~ 53D is set so that the mesh being formed in the frame of base frame 53A presents the rectangle grown crosswise that the length along the direction of thrashing cylinder 16 circumference is longer than the length on direction along the longitudinal direction.

That is; in view of be driven at thrashing cylinder 16 and time the threshing that rotates processes, processed by the threshing for harvesting straw the simple grain grain etc. of gained with the rotation of thrashing cylinder 16 this situation that flows in its direction of rotation, be configured to its mesh in the rectangle grown crosswise longer in the direction of rotation of thrashing cylinder 16 by accepting net 17.Thus, compared with the occasion that undertaking net 17 is configured to the rectangle that its mesh is presented on lengthwise longer in threshing process direction (fore-and-aft direction) of thrashing cylinder 16, simple grain grain etc. is easier to the toe lateral from accepting net 17 and leaks down.It is as a result, it is possible to effectively suppress owing to simple grain grain is from the generation of the decortication grain being suppressed and cause that leaks down of the toe lateral accepting net 17.And, by each undertaking net means 53 being formed as identical shape, it is possible to make the productivity of undertaking net 17 or assembleability improve.

Such as Fig. 3 and as shown in Figure 16, the primary dcreening operation 31 of ragging is made up of single sorting plate 54, and this sorting plate 54 is bolted on screen box 29 with the inclination attitude risen backward being more located top by its sorting downstream, direction.

In the toe lateral (region of about the 1/3 of for the most whole sorting plate 54, front side) of sorting plate 54, overlook viewing rectangular multiple leak down hole 54A arrangement be formed as rank rear leak down hole 54A prostatitis leak down between the 54A of hole staggered.In the rear portion side (region of about the 2/3 of from the point of view of the most whole sorting plate 54, rear side) of sorting plate 54, have sorting sheet 54a, 54b overlook viewing rectangular multiple leak down hole 54B, 54C arrangement be formed as rank rear leak down hole 54B, 54C prostatitis leak down between hole 54B, 54C staggered.

The sorting sheet 54a of the left and right center side being positioned at sorting plate 54 in each sorting sheet 54a, 54b, is stamped and is formed as squamous more the narrowest by its sorting downstream, direction width and the most by the top.And it is positioned at the sorting sheet 54b at the two ends, left and right of sorting plate 54, being stamped is formed as the rectangle that size is shorter than the sorting sheet 54a of left and right center side, more by its sorting downstream, direction the most by the top.

That is, owing to being constituted the primary dcreening operation 31 of ragging with single sorting plate 54, with such as constitute the occasion of primary dcreening operation 31 etc. by being equipped to separate the form of certain intervals in the longitudinal direction by the arrangement of multiple sieve lips (チ ャ Off シ プ) that banding steel plate is constituted compared with, it is possible to realize simplification and the reduction of cost constituted.

Further, by forming the hole 54A that leaks down not possessing sorting sheet 54a, 54b in the toe lateral of the primary dcreening operation 31 of the supply high sorting process thing of simple grain grain containing ratio, the simple grain grain leaked down from the toe lateral of primary dcreening operation 31 grain pan 33 downwards or grain sieve 34 becomes many.It is as a result, it is possible to improve the response rate of the simple grain grain being positioned at a recoverer 21 below grain pan 33 or grain sieve 34.

And, leak down hole 54B, 54C of sorting sheet 54a, 54b is possessed by the most all around arranging formation in the rear portion side of primary dcreening operation 31, in sieving sorting process, the sorting process thing on primary dcreening operation 31 will not bias in the lateral direction but be distributed uniformly.Thereby, it is possible to promote simple grain grain leaking down from respectively leak down hole 54B, 54C.

And then, equip primary dcreening operation 31 by the inclination attitude to raise backward, compared with the occasion with flat-hand position equipment primary dcreening operation 31, in sieving sorting process, the power that the top that sorting process thing is surveyed by primary dcreening operation 31 towards upstream, sorting process direction is released becomes big.Thus; when sieving sorting process, sorting process thing is inhibited, simultaneously towards the conveying in sorting downstream, direction; the up and down motion of sorting process thing becomes fierce; the difference in specific gravity sorting of sorting process thing can be more effectively carried out, thus, promote heavy grain leaking down from respectively leak down hole 54B, 54C; and; can effectively suppress the generation lost for three times that simple grain grain is discharged to machine from outlet 23, it is as a result, it is possible to realize the raising of grain organic efficiency.

Additionally, shorter than the sorting sheet 54a of left and right center side by the sorting sheet 54b at the two ends, left and right of primary dcreening operation 31 is formed as size, it is possible to the hole 54C that leaks down at the both ends, left and right that sorting process thing easily piled up from primary dcreening operation 31 by promotion grain etc. leaks down.It is as a result, it is possible to avoid resulting from accumulation, the efficiency of separation reduction at primary dcreening operation about 31 both ends of the sorting process thing.

It addition, be formed at the hole 54A and possess the ratio of leak down hole 54B, 54C of sorting sheet 54a, 54b of leaking down not possessing sorting sheet 54a, 54b of primary dcreening operation 31, various change can be carried out according to the kind etc. of the grain sorted.

It addition, also can the toe lateral of sorting plate 54 with rank rear leak down hole 54C prostatitis leak down between the 54C of hole staggered arrangement formed multiple leak down hole 54C, this hole 54C that leaks down be formed as overlook viewing time rectangular, there is the rectangular sort sheet 54b of short size.

It is set to that the sorting wind by epimere wind path R1 in the sorting wind of windmill 20 flows towards the second plate 45 of thrashing cylinder 16 through the wind path R4 that is formed in screen box 29 as shown in Figure 3.Thereby, it is possible to prevented the processed material of the flowing processing downstream, direction to threshing by the second plate 45 towards the conveying of thrashing cylinder 16 ambient wind.It is as a result, it is possible to avoid processed material to pile up at the nearby position of the second plate 45 and process to threshing and bring obstacle.

Such as Fig. 3 and as shown in Figure 6, thrashing cylinder 16 is positioned at the threshing tooth 48A of its rear end be positioned at accept the rear of net 17 rear end and in the face of row's stalk mouth 18.It is to say, in the rear end of thrashing cylinder 16, owing to there is not undertaking net 17, so becoming in the state defining larger space about.Thus, even if threshing straw is wrapped on the threshing tooth 48A of thrashing cylinder rear end, this threshing straw also can be rotating under the centrifugal action produced from the end abjection of this threshing tooth 48A with thrashing cylinder 16.It is as a result, it is possible to effectively suppress the delay of the threshing straw caused relative to threshing tooth 48A hook due to threshing straw in thrashing cylinder 16 rear end, it is possible to promote that threshing straw is from the discharge of row's stalk mouth 18.
