A dust exhaust treatment device 30 is provided on the rear side (terminal side) of the handling cylinder 11. The dust treatment device 30 is configured by mounting a dust removal treatment cylinder 31 substantially parallel to the axis of the handling cylinder 11 and communicating with the threshing chamber 12 through a dust removal communication port 33 provided at a rear portion of the threshing chamber 12. The start end portion of the dust removal processing cylinder 31 is mounted on the intermediate plate 34, and a dust discharge communication port 33 is formed between the intermediate plate 34 and the threshing chamber rear plate 17.
Denoted at 35 is a threshing outlet for discharging cereals (objects to be processed) that do not fall from the handle 18 provided below the rear part of the threshing chamber 12. And a plurality of discharge holes 37 are formed, and the rear portion of the cereal discharge port 35 is formed as an open drop port 38. Reference numeral 39 denotes a guide body.
The vertical beam 36 and the discharge hole 37 are respectively provided at positions aligned with the dust discharge communication port 33 in the front-rear direction, and the vertical beam 36 removes cereals that do not fall from the handling net 18 reaching the cereal discharge port 35 as they are. Assists the threshing that does not fall from the handling net 18 to move from the dust discharge communication port 33 to the dust treatment device 30 without falling down and discharging, and loads the threshing chamber 12. To reduce threshing efficiency.

That is, when the cereal discharge port 35 is simply opened, the cereal that does not fall from the handling net 18 reaching the cereal discharge port 35 falls down as it is, and the transfer efficiency to the dust treatment device 30 is reduced. In addition, although the load on the swing sorting device 23 increases, since the vertical rail 36 is provided, only a relatively small object to be processed out of the cereal that does not fall from the handling net 18 falls from the discharge hole 37 to the swing sorting device 23. Thus, the load of the swing sorting device 23 is reduced, and among the cereals that do not fall from the handling net 18, a relatively large object to be treated that does not fall from the discharge hole 37 is a dust discharge communication port of the dust removal treatment device 30. The efficiency of shifting to 33 is improved, and the sorting accuracy and sorting efficiency are improved as a whole.
A second processing device 42 for processing the second item collected by the second conveyor 28 is provided on the front side of the dust removal processing device 30.

The second processing cylinder 44 of the second processing device 42 is configured so as to convey the object to be processed toward the upper end side of the swing sorting shelf 22 in the opposite direction to the conveying direction of the grain supply / conveying device 13. Located on the side of the net 18.

The tip of the second reduction device 45 is opened above the start end of the second processing cylinder 44 of the second processing device 42, and the base of the second reduction device 45 is connected to the end of the second conveyor 28.
46 is a suction dust exhaust fan, 47 is a casing of the suction dust exhaust fan 46, and 48 is a cutter device on the rear side of the threshing device 3.
Thus, on the terminal side of the threshing chamber 12, a rotating body 50 that suppresses the object to be processed from rotating together with the handling cylinder 11 in the threshing chamber 12 is provided.
The rotating body 50 suppresses the co-rotation of the object to be processed on the terminal side of the threshing chamber 12, suppresses the grain from sticking into the threshed cereals conveyed by the cereal supply and transport device 13, and the fourth loss Reduce.
Further, by suppressing the co-rotation of the object to be processed by the rotating body 50, it is possible to improve the uptake to the dust disposal apparatus 30, reduce the load on the threshing chamber 12, and improve the threshing process and the recovery efficiency as a whole.
The rotating body 50 is provided so that the axial center direction thereof is parallel to the axial center direction of the handling cylinder 11.
Therefore, the rotating body 50 can be provided in a compact manner.

The rotating body 50 is provided at least above the handling cylinder shaft 51 of the handling cylinder 11.
The threshing by the handling cylinder 11 is a so-called “under treatment” performed by moving the cereals on the lower surface side of the handling cylinder 11, and the presence of the rotating body 50 does not affect the transportation of the cereals. Since the rotating body 50 is provided at least above the handling cylinder shaft 51 of the handling cylinder 11, the co-rotation suppressing effect of the workpiece is improved.
Thus, the rotating body 50 faces above the dust exhaust communication port 33, the upper part of the dust processing cylinder 31 of the dust processing apparatus 30 near the dust exhaust communication port 33 is opened, and the processed material from the rotary body 50 is opened. Is guided to the dust disposal apparatus 30.
For this reason, it is preferable that the processed material whose rotation with the handling cylinder 11 is prevented by the rotating body 50 is taken into the dust disposal apparatus 30.
That is, a dust exhaust communication port 33 is formed on the side of the dust exhaust processing cylinder 31 inside the side plate 52 of the threshing device 3, and the upper side of the dust exhaust communication port 33 is opened.

Therefore, the rotary body 50 is positioned in the middle of the left and right sides of the handling cylinder 11 and the dust removal processing cylinder 31 in the front view, and the rotation shaft 54 of the rotary cylinder 53 of the rotary body 50 is set to the intermediate plate 34 and the threshing chamber rear plate 17. A plate-like body 55 is provided on the outer periphery of the rotary drum 53 so as to project radially. The tangential direction of the plate-like body 55 is disposed above the dust removal drum 31 of the dust removal treatment device 30. Forms an opening 56.
Therefore, the processed product carried around the outer periphery of the handling cylinder 11 is blown by the rotating body 50 toward the opening 56 of the dust removal treatment apparatus 30 in the tangential direction of the plate-like body 55, and the dust removal treatment apparatus 30. The efficiency of taking over is improved.
That is, the rotating body 50 is configured to rotate in the same direction as the handling cylinder 11, and in the portion where the plate-like body 55 of the rotating body 50 and the tooth handling 11 of the handling cylinder 11 overlap with each other, the rotating object 50 is rotated in the opposite direction. It is made to scatter toward the part 56.
In this case, the rotating body 50 is arranged so that the tip rotation locus of the plate-like body 55 overlaps the tip rotation locus of the tooth handling 11 of the treatment barrel 11 when viewed in the axial direction.
Therefore, the co-rotation suppressing effect of the workpiece of the rotating body 50 is improved.

Thus, the shape of the plate-like body 55 of the rotating body 50 is arbitrary, but in the embodiment of FIG. 10, it is formed in a plate shape having a plurality of projections 57 projecting in the radial direction like a so-called star wheel.
Therefore, while reducing the number of parts, the plurality of protrusions 57 are formed by a single plate member, thereby improving the corotation suppressing effect and reducing the cost.
The protrusions 57 of the rotating body 50 are configured with a receding angle as they reach the tip with respect to the rotation direction (FIG. 10).
Therefore, the entanglement of sawdust on the rotating body 50 is suppressed, and the corotation suppressing effect is improved.
Accordingly, a plurality of plate-like bodies 55 of the rotating body 50 are provided at predetermined intervals in the axial center direction of the rotating drum 53, and each plate-like body 55 is provided with its projection 57 with its phase changed (FIG. 10).
Specifically, the phase is changed so that the front ends of the projections 57 do not overlap each other when viewed from the front (FIG. 10).

Since the phase of the projection 57 of each plate-like body 55 is changed back and forth, the processed material that is prevented from being carried around with the handling cylinder 11 can be dropped downward while being fed forward or backward, improving the joint rotation suppressing effect. Let
In other words, the rotating body 50 not only drops the processed material downward by changing the phase of the projection 57 of the plate-like body 55 before and after the rotation direction, but also provides a feeding action to either the front or the back. Improve the suppression effect.
In addition, due to the feeding action by changing the phase of the protrusions 57 of the plate-like body 55, the fluctuation of the rotational load of the rotating body 50 can be made small and constant.
Further, the tip of the plate-like body 55 of the rotating body 50 is provided as close as possible to the outer periphery of the handling cylinder 11 as long as it does not come into contact.
For this reason, the plate-like body 55 of the rotating body 50 is also removed from the object to be processed which is caught by the base of the tooth handling 11 and is present in the vicinity of the outer peripheral surface of the handling cylinder 11. Improve the effect.

A plurality of plate-like bodies 55 provided in the axial direction of the rotary drum 53 are arranged so that each is positioned between the front and rear teeth 11 on the front and rear of the barrel 11.
Therefore, the object to be processed positioned between the tooth handling teeth 11 is surely guided downward, and the effect of suppressing the rotation of the object to be processed of the rotating body 50 is improved.
Thus, the front portion of the end side portion of the threshing chamber 12 where the handling net 18 does not exist is formed in the dust exhaust communication portion H, and the dust exhaust communication port 33 is formed in the dust exhaust communication portion H.
Further, the rear part of the terminal side part of the threshing chamber 12 where the handling net 18 does not exist is formed in the stabbed grain collecting part S, and the handling cylinder 11 is provided in the dust discharge communicating part H and the stabbed grain collecting part S. Extend the back of the front.
And the said rotary body 50 is provided ranging over both the said dust exhausting communication part H and the stabbed grain collection | recovery part S. As shown in FIG.
Therefore, the rotating body 50 suppresses the co-rotation of the object to be processed in the dust discharge communication portion H and promotes the transition to the dust discharge processing device 30, and the stabbed grain recovery unit S causes the grains to be removed from the threshing cereal. Suppressing the occurrence of stabbed grains and improving the recovery efficiency of stabbed grains.

A guide plate 60 is provided above the dust removal processing cylinder 31 of the dust removal processing device 30 of the stabbed grain collection unit S.
The upper portion of the dust removal processing cylinder 31 of the stabbed grain collecting unit S is surrounded by a casing 61 so that the processed product of the dust removal processing device 30 is prevented from being stuck in the transporting culm on the threshing chamber 12 side. A guide plate 60 is provided above 61 to prevent the processed material from accumulating on the casing 61.
Therefore, an intermediate output pulley 62 is provided at the rear end of the handling shaft 51 of the handling cylinder 11, and an intermediate output pulley 63 is provided on the side of the intermediate transmission pulley 62. The intermediate output pulley 63 is fixed to the intermediate output shaft 64, and the rotary shaft 66 of the rotating body 50 is detachably connected to one end of the intermediate output shaft 64 via a coupling 65.
The other end of the intermediate output shaft 64 is mounted on the rejection input gear case 67. The waste input gear case 67 is mounted with the other end of a waste input shaft 69 that transmits rotation to the waste transport device 68.

Therefore, the rotation transmission path of the rotator 50 is a rotation transmission path from the rear part of the handling cylinder shaft 51 of the handling cylinder 11 to the waste conveying apparatus 68 that conveys the threshed cereal after the cereal supply and conveyance apparatus 13. Is configured to be branched forward and transmitted.
Further, the branch between the rotating body 50 and the waste transporting device 68 is configured to branch and transmit the respective rotations from the front and rear end sides of the intermediate output shaft 64.
For this reason, the rotation transmission path of the rotator 50 uses the rotation transmission path to the waste transporting device 68 and can be configured simply.
That is, since the rotation is input to the rotating body 50 and the waste transporting device 68 from the rear end side of the handling cylinder shaft 51 of the handling cylinder 11, the rotating body 50 is disposed on the rear side of the handling cylinder 11. It becomes easy to install and layout becomes easy.
Further, since the rotating shaft 66 of the rotating body 50 is detachably connected to the intermediate output shaft 64 via the coupling 65, the intermediate transmission pulley 62 of the barrel shaft 51 can be removed at the coupling 65 portion. Thus, the belt 71 can be easily exchanged between the intermediate transmission pulley 62 and the intermediate output pulley 63.

Further, since the transmission between the rotating shaft 66 of the rotating body 50 and the intermediate output shaft 64 is performed by the belt 71, when the mechanism is locked at the time of clogging or the like, the belt 71 can be slid to release the load as a safety device. it can.
Thus, the intermediate portion of the waste input shaft 69 penetrates the tip side waste transport device 68A, and the other end of the waste input shaft 69 has the waste stock source transport chain 70 of the stock source side waste transport device 68B. A waste transport chain drive gear is provided to drive the waste transport chain and transmit the rotation of the waste transport chain to the tip side waste transport device 68A.
Therefore, since the rotary body 50 transmits the rotation from the rotation transmission path of the waste transporting device 68, the rotation transmission mechanism can be configured simply.

(Operation of Example)
The cereals that have traveled by the traveling device 2 and that have been harvested by the reaping unit 4 are transported by the supply transport chain 14 of the cereal supply and transport device 13, supplied to the threshing chamber 12, and threshed by the handling cylinder 11 of the threshing chamber 12. .
The threshed threshing falls from the handling net 18 to the swing sorting shelf 22 and is sorted by swinging the swing sorting shelf 22 and air blown from the tang 19, and the grains are separated from the sorting screen of the swing sorting shelf 22. The grains recovered by the first conveyor 28 and stored by the first conveyor 28 are stored in the Glen tank 5.
In addition, the second item collected on the second conveyor 28 is returned to the second processing unit 42 by the second reduction unit 45, reprocessed by the second processing cylinder 44 of the second processing unit 42, and the swing sorting shelf 22. It is diffused and discharged at the start end.
Further, of the threshing that has been threshed in the threshing chamber 12, a part of the threshing that does not fall from the handling net 18 enters the dust removal processing device 30 through the dust removal communication port 33 at the end of the threshing chamber 12 and is processed.

In addition, the processing object that has fallen on the swing sorting shelf 22 is wind-selected in the wind sorting chamber 21, and among the processed products that do not fall from the swing sorting shelf 22, dust and dust are sucked out by the suction dust exhaust fan 42. Discharged.
Therefore, since the rotating body 50 is provided on the terminal side of the threshing chamber 12 so as to prevent the workpiece from rotating together with the processing cylinder 11, the rotating cylinder 50 causes the processing cylinder 11 on the terminal side of the threshing chamber 12. Is suppressed, the grain is prevented from being pierced into the threshed cereals conveyed by the cereal supply and transfer device 13, and the fourth loss is reduced.
Moreover, since it suppresses that a to-be-processed object co-rotates with the handling cylinder 11 by the rotary body 50, the taking-in to the dust removal processing apparatus 30 is made favorable, the load of the threshing chamber 12 is reduced, and threshing processing and collection | recovery are carried out as a whole. Increase efficiency.

Since the rotating body 50 is provided at least above the handling shaft 51 of the handling cylinder 11, the presence of the rotating body 50 itself has an influence on the conveyance of the transporting cereal that moves on the lower surface side of the handling cylinder 11. In addition, since the rotating body 50 is provided at least above the handling cylinder shaft 51 of the handling cylinder 11, the effect of suppressing the joint rotation of the object to be processed is improved.
In addition, since the rotating body 50 faces the dust exhaust communication port 33 of the dust exhaust processing device 30, it is possible to suppress the rotation of the object to be processed above the dust exhaust communication port 33, and the dust exhaust processing device 30. Improve the incorporation into
Thus, since the rotating body 50 is positioned in the middle of the left and right of the handling cylinder 11 and the dust removal processing cylinder 31 in a front view, the rotating body 50 is provided in the threshing chamber 12 in a compact manner. It is made to act satisfactorily on both of the dust removal processing apparatuses 30, and becomes a rational structure.

The rotating body 50 has the rotating shaft 54 of the rotating drum 53 mounted on the intermediate plate 34 and the rear plate 17 of the threshing chamber, and the rotating body 50 is provided behind the intermediate plate 34. It does not affect the threshing and handling action in the middle part, and can suppress the co-rotation of the object to be processed at the end of the threshing chamber 12 behind the intermediate plate 34, and the stab of the grain to the object to be processed and the conveying cereal It is possible to effectively reduce the fourth loss.
Since the rotating body 50 is arranged so that the tip rotation locus of the plate-like body 55 overlaps with the tip rotation locus of the tooth handling 11 of the handle cylinder 11, the object to be processed that rotates around the tooth handling 11 is rotated. The plate-like body 55 of the body 50 can be removed, and the co-rotation suppression effect of the workpiece of the rotating body 50 is improved.
Further, since the tip of the rotating shaft 54 of the rotating body 50 is provided as close as possible to the outer periphery of the handling cylinder 11 in a range where it does not come into contact, it is caught by the base portion of the handling tooth 11 and near the outer peripheral surface of the handling cylinder 11. The plate-like body 55 of the rotating body 50 can be removed even for the existing object to be processed, and the effect of suppressing the co-rotation of the object to be processed of the rotating body 50 is improved.

A plurality of plate-like bodies 55 are provided at predetermined intervals in the axial center direction of the rotating drum 53 of the rotating body 50 and arranged so that the plate-like members 55 are positioned between the front and rear teeth 11 of the handling drum 11. Therefore, the object caught by the front and rear teeth 11 is removed by the plate-like body 55 of the rotating body 50 and is surely guided downward, and the joint rotation suppressing effect of the object to be processed of the rotating body 50 is reduced. To improve.
Since the rotating body 50 is driven and rotated opposite to each other in the overlapping portion of the plate-like body 55 of the rotating body 50 and the tooth handling 11 of the handling cylinder 11, the rotation of the object to be processed with the handling cylinder 11 is suppressed, The object to be processed is scattered toward the dust removal treatment cylinder 31 by the rotation shaft 54 of the rotating body 50, and the transition to the dust removal treatment apparatus 30 can be promoted.

Thus, the rotating body 50 faces the dust exhaust communication port 33 and the upper part of the dust processing cylinder 31 of the dust processing apparatus 30 in the vicinity of the dust exhaust communication port 33 is open. The treated object that has been prevented from being carried around with the handling cylinder 11 falls down toward the upper part of the dust treatment cylinder 31 near the dust communication port 33 and is taken into the dust treatment apparatus 30 to be succeeded. Increase efficiency.
Thus, the rotating body 50 is configured by providing a plate-like body 55 projecting radially on the outer periphery of the rotating drum 53, and the dust-discharging treatment drum 31 of the dust-discharging treatment device 30 in the tangential direction of the plate-like body 55. Since the opening portion 56 is formed in the upper portion, the processed object that is carried around the outer periphery of the handling cylinder 11 is opened by the rotating body 50 in the tangential direction of the plate-like body 55 of the dust removal processing device 30. The efficiency of takeover is improved.

That is, since the rotating body 50 rotates in the opposite direction in the portion where the plate-like body 55 of the rotating body 50 and the tooth handling 11 of the handling cylinder 11 overlap, the object to be processed is scattered toward the opening 56.
The plate-like body 55 of the rotating body 50 is formed in a plate shape having a plurality of protrusions 57 protruding in the radial direction like a so-called star wheel, so that a single plate is obtained while reducing the number of parts. A plurality of protrusions 57 are formed by the member to improve the corotation suppressing effect and reduce the cost.
Since the protrusion 57 of the rotating body 50 is configured to have a receding angle as it reaches the tip with respect to the rotation direction, the rotator 50 is prevented from being entangled with soot and the co-rotation suppressing effect is improved.
Therefore, a plurality of plate-like bodies 55 of the rotary body 50 are provided at predetermined intervals in the axial direction of the rotary drum 53, and each plate-like body 55 is provided with its projections 57 with different phases. The processed object that has been prevented from being carried around by 11 is dropped downward while being sent to either the front or the back, and is dropped while receiving the feeding action, thereby improving the joint rotation suppressing effect.

Therefore, the front side portion of the terminal side of the threshing chamber 12 where the handling net 18 does not exist is formed in the dust exhaust communication portion H, the dust exhaust communication port 33 is formed in the dust exhaust communication portion H, and the handling is performed. The rear portion of the end side portion of the threshing chamber 12 where the net 18 does not exist is formed in the stabbed grain collection unit S, and the rear part of the handling cylinder 11 is placed in the dust discharge communicating unit H and the stabbed grain collection unit S. Since the rotating body 50 is provided to extend over both the dust discharge communicating portion H and the stabbed grain collecting portion S, the dust discharging communicating portion H allows the rotating body 50 to rotate the workpiece together. It suppresses and accelerate | stimulates the transfer to the dust removal processing apparatus 30, and in the stab grain collection | recovery part S, generation | occurrence | production of the stab grain which a grain enters into the threshed cereal straw is suppressed, and the recovery efficiency of a stab grain is improved.
And since the guide plate 60 is provided above the dust removal processing cylinder 31 of the dust removal processing apparatus 30 of the said stabbed grain collection | recovery part S, the upper part of the dust collection process cylinder 31 of the said stabbed grain collection | recovery part S is a casing. It surrounds by 61 and the processed material of the dust disposal apparatus 30 is prevented from being stuck in the conveying cereal of the threshing chamber 12 side.

Since the guide plate 60 is provided above the casing 61, the guide plate 60 prevents the processed material from accumulating on the casing 61.
Thus, the rotation transmission path of the rotating body 50 is configured by branching the rotation transmission path to the waste transporting device 68 forward, so that the rotation transmission path of the rotating body 50 can be simply configured.
Specifically, the rotation of the handling shaft 51 of the handling cylinder 11 is transmitted to the intermediate output shaft 64 by the intermediate transmission pulley 62, the intermediate output pulley 63, and the belt 71, and the respective rotations before and after the intermediate output shaft 64 are rotated. Since the rotation is transmitted to the body 50 and the waste transporting device 68, the rotation of the rear end side of the handling shaft 51 of the handling drum 11 is branched and transmitted to the rotating body 50 and the waste transporting device 68. It becomes easy to install the rotating body 50 on the rear side of the rear side, and layout becomes easy.
Further, since the rotating shaft 66 of the rotating body 50 is detachably connected to the intermediate output shaft 64 via the coupling 65, the intermediate transmission pulley 62 of the barrel shaft 51 can be removed at the coupling 65 portion. Thus, the belt 71 can be easily exchanged between the intermediate transmission pulley 62 and the intermediate output pulley 63.
Further, since the transmission between the rotary shaft 66 of the rotary body 50 and the intermediate output shaft 64 is performed by the belt 71, the belt 71 can be moved even if a high load is applied to the rotary body 50 due to a mechanical lock or the like at the time of clogging. As a safety device, the load can be released.
