Abstract

A harvesting efficiency is further increased by eliminating grain loss found in sorting performed by a process where objects that are treated by a treating barrel placed at the rear of a grain threshing apparatus, and objects that are treated by a handling barrel are sorted by an oscillating sorter. Below the treating barrel provided at a rear side portion of the grain threshing apparatus is placed a transporting body for receiving objects treated by the treating barrel and transporting the objects forward. The treated objects are loaded once again on to the oscillating sorter for re-sorting, and second objects are transported to the front end of the oscillating sorter by a second returning conveyor. A branch-treating device is provided on the front end of the second returning conveyor. The treating barrel and the transporting body are made easily detachable to facilitate maintenance. Objects falling from the transporting body front portion are detected by a sensor, which prevents clogging.

Technical field

The present invention relates to a technology for reducing a grain loss after threshing by providing a processing drum at the rear of a threshing device in a combine, and in particular, relates to a swing sorting device for processing a processed product processed by the processing drum. The present invention relates to a technology of a transporting body that transports to a front side.

Background art

[0002] Conventionally, in order to improve threshing performance and sorting performance, a dust outlet processing cylinder (processing cylinder) is disposed in parallel at the rear side of the handling cylinder to remove branch attached particles and the like that could not be processed by the handling cylinder. Of the grains that are sent to the processing cylinder and processed in the threshing section, usually 10-15% of the grains are reduced to single grains and discharged through a processing net onto the oscillating sorting device in the lower sorting section. Was.

Furthermore, the second product after the grains are sorted by the sorting device from the grains and straw debris flowing down from the threshing unit is transferred again to the sorting start section of the rocking sorting device via the second conveyor and the second reduction conveyor. It was going to be returned. (For example, see Patent Document 1.)

In addition, as the harvesting speed has been increased, the sorting section has been required to have higher processing capacity (sorting capacity), and measures have been taken to prevent clogging and the like in the sorting section. For example, it is also known to detect the flow rate of straw in the straw chain and adjust the opening of the diaphragm of the sorting unit, and to increase the opening of the diaphragm when there are many objects to be processed. Has become. (See, for example, Patent Document 2.)

[0003] However, when the threshing amount increases due to the increase in speed and efficiency of the combine machine, the processed material of the dust outlet processing drum becomes rough, and the filtration of the processing drum network becomes poor, and the outside of the machine becomes poor. Even if the amount of discharge increases or is filtered on an oscillating sorter, the third-port force is discharged outside the machine without being filtered by a chaff sieve or the like, making it difficult to achieve the normal single-grain rate. Was. In particular, a large number of grains are concentrated in a one-sided position directly below the dust outlet treatment cylinder, which may lead to poor rocking sorting.

[0004] Further, in a conventional combine, there is a technology for adjusting the opening degree of a fuzzy filter by providing a sensor for detecting an amount of an object to be processed deposited on an upper portion of a sorting unit. The sensor is located just behind the dust exhaust roller of the bear (the part where the unprocessed material is re-entered into the sorting unit) (that is, closer to the dust outlet processing cylinder than the left and right center of the sorting unit). The amount of material that has been re-introduced into the upper part of the sorting unit from the dust outlet, contacts the sensor before being evenly leveled by rocking on the sorting unit, and is actually deposited on the upper part of the sorting unit. However, the sensor detected the object to be processed though the amount was not so large, and the opening of the diaphragm sometimes became excessively large. This may increase the burden of wind sorting and reduce the accuracy of sorting rice and straw waste.

In particular, in recent years, the traveling speed at the time of combine harvesting has been increasing in order to increase the efficiency of the harvesting work by the combine, and the amount of unprocessed material processed by the dust outlet processing cylinder tends to increase. is there. As a result, there is a large amount of material to be re-introduced from the dust transport conveyor to the sorting section.Therefore, it is important from the viewpoint of improving the sorting capacity to arrange sensors at appropriate positions on the sorting section. is there.

The invention's effect

[0010] With the above configuration, the unprocessed material that could not be processed by the handling cylinder is sent to the dust outlet processing cylinder for processing, and the processed material that has been processed by the dust outlet processing cylinder and dropped from the processing drum network is It is sent forward by the carrier and re-sorted by rocking sorting installation, and wind sorting is also performed again by Karatomi, so that processing efficiency can be improved and grain loss can be reduced. The sorting width of the sorting device can also be used effectively. Since the branch stalk processing device is located in front of it, the processed material processed by the branch stalk processing device and the processed material processed by the dust outlet processing cylinder overlap on the swing sorting device. Be treated separately and cause clogging Sorting can be performed efficiently without any trouble.

Since the end of the transporting body in the feed direction is located on the sorting section and forward of the end of the handling cylinder in the body traveling direction, the leakage of the processed material that falls from the receiving net due to the shedding action of the handling cylinder. The processed material is put under the part where the lower part is reduced, the leaked material is not biased, and the width of the sorting part in the front-rear direction can be effectively used to improve the processing efficiency. You. In addition, since the rotating direction of the transfer body is such that the processed material is discharged upward from below to the sorting unit, the transferred processed material is discharged to the swing sorting device while being beaten by the swing sorting device. It is possible to increase the sorting efficiency by preventing the grains that cannot be broken and being thrown upward without being hurt and dispersed and falling as rocks on rocking sorting.

The processed material processed by the dust port processing drum is transported forward by the transport body, and the processed material discharged from the front of the transport body hits the diffusion plate, is diffused and falls on the swing sorting device, It is possible to improve the sorting efficiency that does not cause solidification.

In addition, a branch processing device provided at the front end of the second reduction conveyor is arranged in front of the conveyor, and the processed material is dropped on the front of the rocking sorting device. The reprocessed second product can be processed by the spike processing device before re-entering the rocking sorting device, and the yield of the grain without the repetition of the grain with the spike can be reduced. And the sorting efficiency can be improved.

The power is transmitted to the carrier by the sprocket and the chain after gear shifting, and the power can be transmitted by a simple configuration. The position can be adjusted by the transmitting portion, and the error can be absorbed.

Since the carrier is configured to be detachable toward the rear of the machine, during maintenance such as replacement of the carrier and cleaning, the bearing frame is separated from the edge of the gutter and the spline fitting part on the drive shaft side is Separating from the fitting hole on the second sprocket side, the entire carrier can be pulled out from the upper part of the gutter. Further, since the mounting and dismounting are performed together with the bearing frame of the carrier, disassembly of components for fixing the bearing and the bearing is not required, and the mounting and dismounting can be easily performed, and the order of assembly and the direction of assembly are not confused.

[0011] Further, since the sensor for detecting the amount of the object to be processed deposited on the upper part of the sorting unit is disposed behind the exhaust port of the dust transport conveyor, the sensor for the object to be deposited on the sorting unit is disposed. The actual detected deposition force does not become much different due to the processed material immediately after dropping from the dust transport conveyor, and the processed material re-entered into the sorting unit by the dust transport conveyor. The amount of the object to be processed is accurately detected because the amount of the object to be processed is detected at a position where the object and the object that have fallen after passing through the receiving net of the cylinder are shaken and evenly mixed. It is possible to detect the amount of sedimentation.

[0012] Since the sensor for detecting the amount of the object deposited on the upper part of the sorting unit is located below the rear part of the handling cylinder and closer to the handling cylinder than the left and right center of the sorting part, the sensor is deposited on the sorting part. The detected value of the amount of the processed object does not become much different from the actual accumulation amount due to the processed object immediately after falling from the dust transport conveyor, and it is re-input to the sorting unit by the dust transport conveyor. The object to be processed and the object to be dropped that passed through the receiving net of the handling cylinder are mixed by oscillation and the amount of the object to be processed is detected at a position that is evenly distributed. It is possible to detect the accumulation amount of the object.

In other words, the vortex promotes the flow of the second object to the second conveyor.

Next, the branch stalk processing apparatus 10 will be described with reference to FIGS. 8 to 11.

The branch stalk processing unit 10 has the branch stalk processing cylinder 11 arranged below the front end of the second reduction conveyor 40, and the branch stalk processing unit 10 is located on the back side of the drain tank 13, that is, on the right side of the Glen tank 13 when viewed from the front. It is located on the left side of the rocking sorter 27. Therefore, by opening the drain tank 13, it is possible to perform maintenance on the branch stalk processing apparatus 10.

On the outer peripheral surface of the branch stalk processing cylinder 11, treated teeth 11 & 11 are arranged at appropriate intervals. The branch stalk processing cylinder 11 is housed in a cylinder 45, and a supply port 41 is provided at the upper right rear portion (in the direction of travel) of the cylinder 45 to communicate with a second reduction conveyor 40. A tooth bar (fixed-side processing blade) 77 protrudes from the inner surface of the cylindrical body 45.

Further, a discharge port 42 is provided on the lower left side of the cylindrical body 45, and is disposed so as to face the start portion of the swing sorting device 27. At the front or side of the discharge port 42, a paddy guide plate 43 is arranged vertically to guide the falling paddy so that it does not scatter.

[0029] In the above configuration, the flow of the second product from the second reduction conveyor 40 will be described. After the second product is introduced into the branch processing apparatus 10 from the supply port 41, the branch processing cylinder 11 , The processing teeth 1 la * 1 la * provided on the outer periphery of the branch stalk processing cylinder 11 and the tooth bar 77 projecting from the inner surface of the cylindrical body 45 forming the outer frame of the branch stalk processing apparatus 10. As a result, the branch stalks are removed and conveyed to the outlet 42 and discharged downward from the outlet 42, and then hit the paddy guide plate 43 arranged in the vicinity of the outlet 42. It is guided so as to fall on the sorting start portion of the swinging sorting device 27, that is, on the front surface of the upstream grain plate 30.

In the present embodiment, the arrangement of the paddy guide plate 43 is in front of the discharge port 42, and the opening force of the discharge port 42 is configured to be wider toward the center side when viewed from the front of the machine body.

An angle formed between B and a vector A (arrow A) in the front-rear direction) is provided in the upper half of the inner wall of the processing chamber 29 with Θ (that is, in a substantially spiral shape).

As described above, by providing the reed valve 65 having a lead angle Θ on the inner wall surface of the processing chamber 29, the rear of the processing chamber 29 (the discharge direction) The transfer of the unprocessed material to the processing room 29 is promoted, and the unprocessed material transferred from the handling room 28 to the processing room 29 through the dust outlet 23 moves quickly in the processing room 29. Therefore, the unprocessed material stays in the rear part of the processing chamber 28 and the front part of the processing chamber 29 (that is, in the vicinity of the dust outlet 23), and the backflow of the unprocessed material from the processing chamber 29 to the processing chamber 28 is prevented. The sorting ability is improved.

In the present embodiment, the reed valve 65 (the reed valve 63 on the handling cylinder case and the reed valve 64 on the processing cylinder case) is disposed in front of the processing chamber 29 in which the dust outlet 23 is provided. However, the present invention is not limited to this, and it may be provided in the middle or the rear of the processing chamber 29 according to the amount of unprocessed material generated.

[0035] Further, the reed valve 65 is composed of two members, a handle case side reed valve 63 and a treatment month side reed valve 64, which are attached to the handle case 61 and the treatment month case 62, respectively. By providing a reed valve 65 over the upper half of the processing chamber 29, the working area of the reed valve 65 can be increased, and the ability to transport unprocessed materials is improved. Also, cleaning and disassembly at the time of cleaning and maintenance in the processing chamber 29 are easy and excellent in maintainability.

Further, as shown in FIG. 6, the front end 63a of the handle case side reed valve 63 constituting the reed valve 65 and the rear end 64b of the processing cylinder case side reed valve 64 are front and rear in a side view. The unprocessed material that has overlapped (overlapped) in the direction, that is, the transport direction of the unprocessed material, and that has moved along the working surface of the processing cylinder case-side read valve 64, is surely Delivered to the working surface of valve 63. Therefore, even though the reed valve 65 is divided into two members, it is possible to maintain a high ability to transport the unprocessed material.

In this embodiment, the handle case side reed valve 63 is located at the upper end of the dust outlet 23 in side view. Forces Four are provided parallel to the upper position of the processing chamber 29 from the front end of the dust outlet 23 to the substantially rear end of the handling chamber 28. In addition, the processing cylinder case side reed valve 64 is parallel to the upper part of the processing chamber 29 from the middle part of the dust outlet 2 in the vertical direction, from the front end of the dust outlet 23 to the substantially rear end of the dust outlet 23. It is provided so that it can be reliably transported from the dust outlet 23 into the processing chamber 29.

[0037] Further, the size of the lead angle Θ is from the rear end 63b of the handling cylinder case-side reed valve 63 in the transport direction of the unprocessed material to the front end 64a of the processing cylinder case-side reed valve 64. It is preferable that the length L1 is configured to be equal to or more than half of the opening width L2 of the dust outlet 23 in the transport direction of the unprocessed material (Ll≥ (l / 2) X L2).

With this configuration, the unprocessed material transferred from the dust outlet 23 into the processing chamber 29 can be quickly moved in the discharge direction (rearward), and the rear of the handling chamber 28 and the front of the processing chamber 29 ( That is, stagnation of unprocessed material in the vicinity of the dust outlet 23) and backflow of the unprocessed material from the processing chamber 29 to the handling room 28 are prevented, and the threshing / sorting ability is improved.

If the reed angle Θ is too large, the friction between the working surface of the reed valve 65 and the unprocessed material becomes excessive, so that the load related to the rotational drive of the processing cylinder 22 increases, and the paddy comes off or crushes. May cause. Therefore, it is necessary to appropriately select the lead angle により according to the use conditions of the combine.

Further, as shown in FIG. 6, from the center of the processing chamber 29 away from the dust outlet 23 to the rear, the partition plate 66 (66) having no lead angle Θ (Θ 0) is It is provided on the inner wall of case 62. In this way, from the central part to the rear part of the processing chamber 29, rather than preventing the unprocessed material from being immediately conveyed backward, rubbing and performing sufficient separation 'selection', the separation 'selection (filtration) ) To reduce losses.

In addition, the processing drum net 24 shown in FIG. 5 is made of a press net provided with a large number of punched holes in the plate material, so that the flowability of the processed material (below the processed material) is lower than that of a crimped net / corn cape. Ease of dropping). In addition, manufacturing costs can be reduced.

Further, as shown in FIG. 6, the rotating processing teeth 22 b ′ 22 b ′ ″ of the dust outlet processing cylinder 22 pass between the resistance plates 67 provided on the inner wall of the processing cylinder case 62. With this configuration, even when the amount of unprocessed material transported into the processing chamber 29 is large (for example, during harvesting work at high speed), the paddy stays on the processing drum 24 and the paddy Efficient long straw that inhibits filtration Can be shredded, promotes separation / sorting (filtration) and can reduce loss

. Further, at this time, by cutting the tip of the treated tooth 22b ′ 22b into a blade shape, it is possible to easily cut the long straw.

The portion is disposed on the front side in the fuselage advancing direction from the end end side plate 59 of the handling cylinder 21, and partially overlapped with the rear portion of the handling cylinder 21 in the front-rear direction. Further, the branch stalk processing apparatus 10 is provided in front of the carrier 50 and the dust port processing cylinder 22, and is arranged so as to overlap the handling cylinder 21 in a side view.

Further, in a portion where the transfer body 50 and the handling cylinder 21 do not overlap in a side view, a side wall 54 is fixedly provided on the handling cylinder 21 side of the receiving tub 52 so as to prevent the processed object from falling. On the other hand, at the portion where the transport body 50 and the handling cylinder 21 overlap, that is, at the transport end, the handling cylinder 21 side of the receiving tub 52 is opened to form a discharge portion 52a. A plate-like blade 56 is fixed to a drive shaft 55 of a screw 53 located at the discharge portion 52a, and the processed material is discharged to the left and right center sides of the swinging sorting device 27 by the rotation of the blade 56. I have to.

A pulley 48a is fixed to the other end of the input shaft 58, and the pulley 48a and a pulley 48b fixed to the drive shaft 34 of the dust outlet processing cylinder 22 are wound around a belt 57. In this way, the driving shaft 34 of the dust port processing cylinder 22 is interlocked and connected to the driving shaft 34 of the dust port processing cylinder 22 via the pulleys 48a'48b, the belt 57, and the gears 47a'47b. Carrier 5 from 34 The power is transmitted to the 0 drive shaft 55 so that the carrier 50 can be rotationally driven in accordance with the rotation of the dust port processing cylinder 22.

Another embodiment of another drive structure will be described with reference to FIGS. A cylindrical processing boss 100 is connected to the front end of the drive shaft 34 of the dust outlet processing cylinder 22, and a processing cylinder drive shaft 101 is connected to the processing cylinder boss 100. In other words, the processing cylinder drive shaft 101 and the drive shaft 34 are connected so as to rotate integrally with each other via the same processing boss 100. The processing drum boss 100 is rotatably supported by a gear box 102 supported by the body frame 2.

As shown in FIG. 16, an intermediate shaft 103 is rotatably supported in the gear box 102 in parallel with the processing drum boss 100, and is provided on the processing drum boss 100 in the gear box 102. The first gear 104 and the second gear 105 provided on the intermediate shaft 103 mesh with each other and are arranged in a transmission state. One end (rear end) of the intermediate shaft 103 protrudes outside the gear box 102, and the first sprocket 106 is fitted and fixed to the protruding portion.

On the other hand, as shown in FIG. 16, a spline fitting portion 55a having a rectangular cross section is formed at a front end of the drive shaft 55 of the screw 53 over a predetermined length in front of the carrier 50. A second sprocket 107 having a fitting hole 107a in which the spline fitting portion 55a can be fitted and separated is provided rotatably with respect to the machine base 2, and the second sprocket 107 and the first sprocket described above are supported. 106 is configured to be linked by a chain 108. Therefore, if the spline fitting portion 55a on the drive shaft 55 side is fitted in the fitting hole 107a on the second sprocket 107 side, the carrier 50 rotates in conjunction with the rotation of the dust port processing cylinder 22. become.

However, the drive configuration of the transport body 50 is not limited, and may be a chain type or the like. In addition, a configuration may be adopted in which power is transmitted from a lower sorting device or the like that is not provided only from the dust outlet processing cylinder 22. Monkey

On the other hand, as shown in FIGS. 17 and 18, the rear end of the drive shaft 55 of the transport body 50 is supported by a bearing frame 110, as shown in FIGS. Supported. As shown in FIG. 18, the bearing frame 110 is formed in a substantially pentagonal shape when viewed from the front, and a drive shaft 55 and a screw 53 are rotatably mounted at the center thereof (bearing portion 110a). And the bearing frame 110 Bolt holes are formed in the bent portions 111 and 112 on the lower side of the container, and the entire carrier 50 is detachably formed at the edge of the funnel-shaped receiving gutter 52 by the bolt 113.

With this configuration, as shown in FIG. 12, FIG. 13, and FIG. 14, when the processed material leaks down from the dust port processing cylinder 22 through the processing cylinder network 24 and falls onto the transporting body 50, The processed material is conveyed to the discharge end 52a, which is the end of conveyance of the conveyance body 50, by the rotation of the screw 53, and is discharged from the discharge part 52a to the left and right center sides of the swing sorting device 27 by the rotation of the blade 56. Because Therefore, the dust is not dropped directly from the dust outlet processing cylinder 22 to the second conveyor 37, and the second material is dispersed and returned to the swing sorting device 27, and the sorting width of the swing sorting device 27 is reduced. This effectively re-sorts the transported material to reduce grain loss and increase grain processing.

[0050] Further, according to the above-described configuration, in maintenance such as replacement and cleaning of the carrier 50, the bonolet 113 is removed, the bearing frame 110 is separated from the edges 52b and 52c of the acceptance 52, and the horse driving shaft The spline fitting portion 55a on the 55 side is separated from the fitting hole 107a on the second sprocket 106 side, so that the entire carrier 50 can be pulled out from the upper part of the receiving gutter 52.

However, the drive configuration of the transport body 50 may be a pulley type or the like that is not limited to the above-described embodiment, and may be configured to transmit power from a sorting device or the like below the dust outlet processing cylinder 22. You can do it.

Here, the drive shaft 55 of the transport body 50 is configured to rotate counterclockwise when the transport body 50 is installed on the left side of the handling cylinder 21 in a front view as shown in FIG. It is configured. By setting the rotation direction of the screw 53 and the blade 56 in the counterclockwise direction in this way, the processed material conveyed by the screw 53 is discharged by the blade 56 onto the oscillating sorter 27 by underslow. Thus, the processed material can be discharged from the discharge portion 52a of the receiving tub 52 without hitting the chaff sheave 33 of the swinging sorter 27 or the like. In this embodiment, the processed material is discharged from the discharge section 52a onto the swinging and sorting device 27 with an ordinal opening, but the screw 53 and the blade 56 are rotated clockwise to discharge the processed material. It can also be configured to discharge by bar throw.

With this configuration, when the processed material drops from the dust outlet processing drum 22 through the processing drum network 24 and falls into the carrier 50, the processed material is transported by the rotation of the screw 53. It is conveyed to the discharge section 52a, which is the conveying terminal end of the sending body 50, and is discharged from the discharge section 52a to the left and right center sides of the swing sorting device 27 by the rotation of the blades 56. Therefore, the dust is not dropped directly from the dust outlet processing cylinder 22 to the second conveyor 37, and the second material is dispersed and returned to the swing sorting device 27. The processed material conveyed using the width can be re-sorted to reduce the grain loss and increase the grain processing.

In the discharge section 52a, as shown in FIGS. 12 and 27, a guide plate 115 and a diffusion plate 116 are provided on the side of the carrier 50. That is, in the central part of the fuselage where the front part of the carrier 50 and the rear part of the handling cylinder 21 overlap in side view, the receiving net 20 is not provided, and this part substantially overlaps with the receiving net 20 in front view. As described above, the guide plate 115 is provided, and the diffusion plate 116 is provided below the guide plate 115.

It extends obliquely downward toward the tangential direction of the receiving net 20 below. Further, a diffusion plate 116 extends from substantially below the left and right centers of the guide plate 115 to the lower side of the oblique body at the center. That is, on the front discharge side of the transport body 50 where the dust outlet 23 and the blades 56 of the transport body 50 are located, the guide plate 115 is disposed above the left and right central sides of the body of the transport body 50 in rear view. The upper end of the guide plate 115 is fixed to the center side of the machine body of the processing drum net 24, and is disposed obliquely downward toward the left and right center sides of the machine body.The lower end is fixed to the rear part of the receiving net 20. A diffuser plate 116 is arranged to be inclined downward to the center of the fuselage and directed downward from the left and right halfway. With such a configuration, the spike sticking particles and the like, for which the terminating force of the receiving net 20 was not able to be threshed, are guided by the guide plate 115 and thrown from the dust outlet 23 into the dust outlet processing cylinder 22. Then, the processed material after being processed by the dust outlet processing cylinder 22 is conveyed forward by the conveyance body 50 therebelow, and is scooped up by the blades 56 at the front, and is discharged obliquely upward to the left and right center sides of the machine body with an underslow. Is done. At this time, the processed material hitting the guide plate 115 is guided so as to bounce downward on the center side of the machine body. Further, the thrown-out processed material hits the diffusion plate 116 arranged on the back side of the guide plate 115 to be diffused and released onto the swing sorting device 27, and the processed material is dispersed without being hardened and is swing-sorted to be sorted. Improve efficiency.

Next, a second embodiment of the carrier will be described. In the processing chamber 29 as shown in FIGS. 19 and 20, a transport body 60 is provided horizontally below the dust outlet processing cylinder 22 in the front-rear direction so as to overlap the dust outlet processing cylinder 22 in plan view.

Here, as described above, in the case where the second reduction conveyor 80 is connected to the transport start end of the transport body 60, the second reduction conveyor 80 is inclined rearward and is located at the transport start end of the transport body 60. As a result, the overall length of the second reduction conveyor 80 can be shortened compared with the conventional case where the second reduction conveyor is inclined forward and connected to the branch stalk processing device, reducing the weight and cost. Reduction can be achieved. In addition, since the second reduction conveyor 80 does not wrap with the lifting conveyor 38, the width of the threshing section 12 can be reduced, the capacity of the drain tank 13 can be increased, and the threshing section 12 side of the drain tank 13 can be increased. Side plate can be simplified.

In the present embodiment, the transport body 60 is arranged coaxially with the branch incision processing cylinder 11 in the branch incision processing apparatus 10, but as shown in FIG. The stalk processing device 10 is disposed below the transfer end of the transfer body 60 so as to be inclined. It is also possible to adopt a configuration in which the sprue processing cylinder 11 is loaded from above.

[0058] In such a configuration, the second product having many branch spikes and the processed material of the dust outlet processing cylinder 22 are fed to the branch process apparatus 10 through one path including the second reduction conveyor 80 and the transport body 60. As a result, the branch vein can be removed and the branch vein processing can be performed efficiently, and the number of parts can be reduced as compared with the first embodiment. Further, although there are many culm cuts in the processed material by the dust outlet processing cylinder 22, the culm can be crushed by the branch stalk processing apparatus 10, so that the sorting ability can be improved.

Next, a third embodiment of the carrier will be described.

In the processing chamber 29 as shown in FIGS. 22 and 23, a transport body 85 is provided horizontally below the dust outlet processing cylinder 22 in the front-rear direction so as to overlap with the dust outlet processing cylinder 22 in a plan view.

The transporting body 60 has a transporting end (the front side in the machine body traveling direction) extending to the rear end of the handling drum 21 and is connected to the branch branch processing apparatus 68.

[0060] The carrier 85 receives the processed material falling from the dust port processing drum 22 through the processing drum network 24, and reverses the processed material in the direction opposite to the direction in which the dust-removed material is fed by the dust port processing drum 22. It is conveyed by rotation of the screw 87 to the conveying end portion in the direction, and is fed into the branch stalk processing device 68. In the branch stalk processing device 68, the branch stalk is removed by the branch stalk processing cylinder 69 in the same manner as described above, and then the stalk is fed to the swing sorting device 27.

Next, a fourth embodiment of the carrier will be described.

As shown in FIG. 24, in the present embodiment, the two-stage processing month of the dust outlet processing cylinder 24 and the second processing month 78 disposed below the same.

The dust processing port processing cylinder 37 and the second processing cylinder 78, both of which are configured in a screw type, have different rotation speeds. Below the dust processing port processing cylinder 24, a sun-type coarse processing cylinder network is provided. 24 is stretched, and below the second processing month 78, a second processing net 79 is stretched below the mesh.

The dust outlet processing cylinder 24 is re-processed while the receiving port communicates with the dust outlet 23 of the handling cylinder 21 and sends the debris of the handling cylinder 21 to the rear of the machine, and passes through the processing drum network 24. The filtered material is passed through the second processing cylinder 78. Discharge up. The second processing cylinder 78 reprocesses the filtrate from the dust outlet processing cylinder 22 while sending it to the front of the fuselage, and oscillates the processed material through the second processing net 79 with the rocking sorting device 27. Return to the swing body 49. In the two-stage treatment of the dust outlet treatment cylinder 22 and the second treatment cylinder 78, the number of attached grains of the branch streak is reduced, and the reprocessing distance of the deagglomerated material of the handling cylinder is secured, so that the sizing can be increased. It becomes possible.

Further, in this embodiment, the gear externally fitted to the front end of the rotary shaft of the dust transport conveyor 50 and the gear externally fitted to the front end of the rotary shaft of the dust port processing cylinder 22 are combined with each other. The ratio of the number of rotations of the dust transport conveyor 50 to the number of rotations of the dust port processing cylinder 22 is substantially constant. Therefore, a predetermined ratio is set between the amount of the workpiece to be separated and captured by the dust transport conveyor 50 and the amount of the workpiece transported forward by the dust transport conveyor 50. Can be maintained. At the rear end of the rotating shaft of the dust transfer conveyor 50 and the dust port processing cylinder 22, the rotation of the dust transfer conveyor 50 and the dust port processing cylinder 22 such as gears, belts and pulleys, or chains and sprockets, etc. It is also possible to configure to distribute the driving force while maintaining the number ratio almost constant.

The object to be processed, which has fallen downward through the holes (mesh) provided in the processing drum network 24, is forwarded by the dust transport conveyor 50 (that is, in the direction opposite to the transport direction of the dust outlet processing drum 22). Direction). Then, the object to be processed is re-introduced into the sorting section 17 from a dust discharging roller 50a provided at the front end of the dust transport conveyor 50. More specifically, the material to be processed falls on the chaff sheave 33 at a position above the floe plate 39 (that is, above the first conveyor 36).

In this embodiment, the dust transport conveyor 50 is a screw-type conveyor. The present invention is not limited to this, and a belt-type conveyor may be used. Further, the position where the object to be treated is re-introduced by the dust transport conveyor 50 may be on the upstream grain plate 30.

Hereinafter, the sensor 51 will be described with reference to FIGS. 5, 25, and 26.

The sensor 51 detects the amount of straw accumulated on the upstream grain plate 30 and the chaff sheave 33 provided at the upper front of the sorting unit 17 and adjusts the opening degree of the chaff sheave 33. 51a and a sensor section 51b.

The contact body 51a is an elongated plate-like member, and one end of the contact body 51a is attached to the rotation shaft of the sensor section 51b. It is attached. The sensor unit 51b is a rotation angle sensor such as a resorno, a rotary potentiometer, a rotary encoder, etc., and can detect the attitude of the contact body 51a with respect to the aircraft in the form of an angle.

[0069] As shown in Fig. 26, the vertical thickness T [mm] of the object to be treated (mixture of paddy and chopped straw waste) deposited on the chaff sheave 33 is measured from the upper surface of the chaff sheave 33 to the sensor section 51b. The height H [mm], the length R [mm] of the contact body 51a, and the rotation angle φ [rad] of the contact body 51a detected by the sensor unit 51b. When <H_R, φ> 0, T = H_R X cos Θ. The rotation angle φ of the contact body 51a is set to zero when the contact body 51a is facing directly downward (when the contact body 51a is in contact with the workpiece or not), and the contact body 51a is conveyed rearward. It is defined to take a positive value when it comes into contact with the object and turns backward.

On the other hand, as far as the sorting unit 17 can separate the straw waste and the rice with high accuracy, the amount of dropping from the sheave sieve 33 to the grain sieve 32 is increased as much as possible, and the opening degree of the chaff sheave 33, which maximizes the sorting processing capacity, is improved. The relationship with the thickness T [mm] of the material to be treated (mixture of paddy and chopped straw waste) is determined in advance by experiments and the like.

Then, the opening degree of the chaff sheave 33 is adjusted based on the information about the rotation angle φ from the sensor 51 (that is, the information about the amount of the material to be processed deposited on the chaff sheave 33 and the upstream grain plate 30).

[0070] For example, when the object to be processed is piled up just under the sensor 51 and not piled up in the chaff sheave 33 and other places on the upstream grain plate 30, the sensor 51 The thickness T [mm] at which the rotational angle φ force is also detected cannot be said to accurately reflect the actual amount of the material deposited on the chaff sheave 33 and the upstream grain plate 30 ( In this case, the deposition amount is estimated to be larger than the actual deposition amount.) Therefore, the fact that the material to be treated is evenly distributed on the chaff sheave 33 and the upstream grain plate 30 is not only from the viewpoint of accurately obtaining the thickness T [mm], but also from the viewpoint of performing the sorting efficiently. It is very important.

In practice, the swinging of the sorting unit 17 causes the processed material to be evenly distributed on the chaff sheave 33 and the upstream grain plate 30. In particular, when the traveling speed during harvesting is high (the amount of harvested material is input into the threshing unit 12 and the sorting unit 17 per unit time is large), the objects to be treated that have fallen from the In some cases.

Therefore, the mounting position of the sensor 51 is a position slightly away from a local “mountain” generated by the workpiece to be re-entered into the sorting unit 17 by the dust transport conveyor 50, and is set by the dust transport conveyor 50. It is preferable that the object to be re-introduced into the sorting unit 17 and the object to be processed that have dropped through the receiving net 20 are mixed and arranged at a uniform position by rocking. .

In the present embodiment, as shown in FIGS. 5 and 25, the rotation axis of the handling drum 21 is closer to the left side than the left and right center of the sorting unit 17 (left and right center line C-C shown in FIG. 25). The rotation axis of the mouth processing cylinder 22 is shifted to the right. Accordingly, the dust transport conveyor 50 for transporting the workpiece generated in the dust outlet processing cylinder 22 also has its rotation axis shifted to the right side from the left and right center of the sorting unit 17, and the dust discharging roller 50 a is separated from the sorting unit. The object to be processed falling on 17 forms a mountain 70 at a position closer to the right than the left and right center of the sorting unit 17.

Further, the sensor 51 is disposed behind the dust-discharge roller 50a of the dust-feeding and conveyer 50 (that is, on the downstream side in the conveying direction of the object to be processed in the sorting unit 17) and at a position longer than the left and right centers of the sorting unit 17. It is located closer to 21. Therefore, the detected value of the amount of the object deposited on the sorting unit 17 is not affected by the peak 70, and the actual accumulated amount force does not greatly deviate. The amount of the object to be processed is detected at a position where the object to be re-charged and the object that has dropped through the receiving net 20 are mixed and evenly leveled by rocking. Accordingly, it is possible to accurately detect the deposition amount of the object to be processed.

Note that the position of the sensor 51 is: (1) the body of the dust-feeding conveyor 50, which is behind the dust-discharge roller 50a (that is, downstream of the sorting unit 17 in the transport direction of the workpiece), or (2) the handling cylinder The same effect can be obtained by arranging so as to satisfy either one of the lower part of the rear part and the handling cylinder 21 from the left and right center of the sorting part 17.

In the present embodiment, the sensor 51b of the sensor 51 is a force formed by a rotation angle sensor such as a resolver, a rotary potentiometer, and a rotary encoder. The portion 51b may be a contact-type switch, and the switch may be turned on and off when the contact body 51a rotates by a predetermined angle or more. Further, a capacitance sensor or the like may be used.

[0073] A guide plate 81 is provided behind the carrier 50. The guide plate 81 is disposed below the processing cylinder 22 and above the swing sorting device 27, as shown in FIGS. The front end position of the guide plate 81 is located forward of the rear end of the processing drum 24, and the rear end position of the guide plate 81 is located behind the rear end of the swinging sorting device 27. Is formed. The guide plate 81 is disposed between the suction fan 25 and the processing cylinder cover 76 with substantially the same width as the horizontal direction of the processing month 22, and is fixed by fixing means such as bolts.

The guide plate 81 is for guiding the straw and the like inside the dust sending port processing cylinder 22 to the outside of the machine body, and flips the straw and the like inside the processing cylinder 22 by the rotation of the wings 91. It is discharged below the processing drum 22 and guided to the outside of the machine by the guide plate 81. In this way, by providing the guide plate 81, the straw waste can be discharged to the outside of the machine without being mixed into the carrier 50 and the swing sorting device 27. The installation of the guide plate 81 is optional and may function as a combine without the installation.
