  The air split 66 has an angular range in which a horizontal rotation shaft 66x (see FIG. 9) orthogonal to the blowing direction is a rotation center, and the upper surface 69 and the lower surfaces 71 and 72 are obliquely upward toward the downstream side in the blowing direction. Further, the rotation shaft 66x of the air split 66 is positioned in the middle of the air blowing direction, and rotates so that the upstream side and the downstream side of the rotary shaft 66x move up and down. It is like that. Both ends of the rotation shaft 66x of the air split 66 are pivotally supported on both side walls 18S of the sorting chamber 18. Further, when the inclination angle of the airflow 66 with respect to the horizontal plane (hereinafter also simply referred to as the inclination angle) is increased to the maximum by the rotation of the airflow 66, the end of the airflow 66 on the tang 16 side is the bottom surface portion of the air outlet 65. It is comprised so that 68 may be adjoined or contacted (refer FIG.5 and FIG.6).

  Further, the top surface portion 67 is also in the same direction as the airflow 66 within an angular range in which the horizontal rotation shaft 67x orthogonal to the air blowing direction is the rotation center and the lower surface is obliquely upward toward the air blowing direction downstream side. It is configured to rotate. Although the rotation shaft 67x of the top surface portion 67 is located at the end of the top surface portion 67 on the side of the Karatsu 16 in the illustrated example, it can be located at the middle of the blowing direction or at the downstream side of the blowing direction, either way. What is necessary is just to rotate so that the downstream side of the top | upper surface part 67 may go up and down. Both ends of the rotation shaft 67x of the top surface portion 67 are also pivotally supported on both side walls 18S of the sorting chamber 18.

  In such a structure, the distribution ratio of a certain amount of wind supplied from the tang 16 to the upper air passage 74 and the lower air passage 75 is determined by the ratio of the opening degrees of the upper air passage 74 and the lower air passage 75. . Therefore, when the top surface portion 67 and the wind split 66 rotate in the same direction in the direction in which the opening degree of the lower air passage 75 decreases, the air volume of the lower air passage 75 decreases, and conversely the upper air passage. As the airflow of the airflow 74 increases, the airflow direction of the lower air passage 75 changes according to the angle change of the lower surface of the airflow 66, and the airflow direction of the upper airway 74 changes the angle of the top surface portion 67 and the lower surface of the airflow 66. It changes according to the angle change. On the other hand, if the top surface portion 67 and the wind split 66 are rotated in the same direction in the direction in which the opening degree of the lower air passage 75 increases, the air volume of the lower air passage 75 increases, and conversely the upper air passage. The airflow at 74 decreases. The wind direction of the lower air passage 75 changes in accordance with the change in angle of the lower surface of the wind divider 66, and the wind direction of the upper air passage 74 changes in accordance with the change in angle of the top surface portion 67 and the lower surface of the wind divider 66. That is, the wind direction and the air volume of the upper air passage 74 and the lower air passage 75 can be adjusted simultaneously.

(Processing amount detection sensor)
Although the inclination angle of the air split 66 and the top surface portion 67 may be fixed regardless of the amount of processed material, a processing amount detection sensor 95 for detecting the amount of processed material on the swing sorting shelf 20 is provided, and this processing amount detection sensor On the basis of the detection result of 95, when the amount of the processed material on the shelf increases, the inclination angle of the air split 66 and the top surface portion 67 with respect to the horizontal plane is decreased, and when the amount of the processed material on the shelf decreases, It is also preferable to provide a control device (not shown) that increases the inclination angle of the surface portion 67 with respect to the horizontal plane. As a result, even if there is an increase or decrease in the amount of processed material, the inclination angle of the wind rate 66 and the top surface portion 67 is automatically adjusted appropriately according to the detected result of the processed material amount on the swing sorting shelf 20, and the optimum grain loss and A sorting state can be obtained.

  The processing amount detection sensor 95 can be configured by using a known contact or non-contact sensor. In the illustrated example, the terminal side (second treatment product reducing port side or front end side) portion of the receiving plate 42 of the second processing chamber 40 and the lower end portion of the intermediate partition wall 11K of the sting particle recovery chamber 11E are connected by a sensor stay 95S. A rotation amount detection device 96 such as a potentiometer is attached to the sensor stay 95S, and a float 97 is attached to the detection shaft 96x of the rotation amount detection sensor 96 in a suspended state. A layer of the object to be processed that moves on the transfer shelf 22 in contact with the object to be processed that moves on the transfer shelf 22 of the swing sorting shelf 20 and that rotates while rotating in the moving direction of the object to be processed. The thickness is detected by the rotation amount detection device 96.

  In the case of the type in which the float 97 rotates as in the illustrated example, the rotation center of the float 97 (that is, the detection shaft 96x in the illustrated example) is relative to the flow of the second reduced product or the entire processed product on the shelf. It is preferable that the configuration is substantially right-angled and inclined with respect to the swinging direction of the swing sorting shelf 20 in a plan view. As a result, the flow direction of the processed product on the shelf and the rotation direction of the float 97 contacting the same coincide with each other or close to each other, so that the float 97 operates smoothly and is accurate and sensitive to changes in the amount of processed product. To respond to.

  In this case, in order to make the operation of the float 97 smoother, with respect to the rotation center of the float 97, one side in the rotation center direction in the float 97, particularly on the downstream side in the transfer direction of the transfer shelf 22 as in the illustrated example. It is also a preferable form that a close-up plate 98 extending in a direction substantially orthogonal (substantially parallel to the rotation direction of the sensor float 97) is erected. As a result, even if the moving direction of the processed product on the shelf shifts due to the swinging action by the transfer shelf 22, the moving direction is regulated by the approach plate 98 in the vicinity of the float 97. The rotation direction of the float 97 in contact therewith substantially coincides with the float 97, so that the float 97 operates more smoothly.

  In addition, the shape of the float 97 is at least a portion in contact with the processed product on the shelf as in the illustrated example (in the illustrated example, the surface on the upstream side in the movement direction of the processed product in the non-contact state where there is no processed product on the shelf) However, it is preferable that it is an arcuate curved surface that protrudes toward the middle part in the sliding direction of the processed material on the shelf.

  On the other hand, the amount of processed material is generally unevenly distributed on the transfer shelf 22, and the amount of processed material in the vicinity of the lower portion of the second processed material reducing port 43 is particularly large. Therefore, it is desirable that the processing amount detection sensor 95 is configured to detect the amount of the processed product on the shelf of the swing sorting shelf 20 in the vicinity of the second processed product reducing port 43. For this reason, in the illustrated example, the float 97 is disposed in the vicinity of the second processed material reducing port 43.

(Sheave cleaning device)
As shown in FIGS. 5 to 7 and 10, in the present embodiment, the first cleaning body 100 and the second cleaning body 200 that perform cleaning by reciprocating in the left-right direction on the first sheave 23 are relative to each other. Thus, the first sheave 100 is positioned so that the first cleaning body 100 is positioned on the side of the handle 10 that is in contact with the grain pod (feed chain 13B side) and the second cleaning body 200 is positioned on the side of the handle 10 that is in contact with the culm. 23 are juxtaposed in the left-right direction.

  If the 1st cleaning body 100 and the 2nd cleaning body 200 move on the sheave 23 and exhibit the cleaning effect, the shape and structure will not be specifically limited, but the 1st cleaning body 100 and the 2nd of the example of illustration are shown. The cleaning body 200 includes a plurality of cleaning tools 80, 80, 80... Arranged at predetermined intervals in the left-right direction, and each cleaning tool 80 is shown in detail in FIGS. A diffusion plate portion 81 is provided along the front-rear direction, and a scraper portion 82 is in contact with the upper surface of each sheave member 23b of the first sheave 23 to remove deposits.

  The cleaning tools 80, 80, 80... Of the first cleaning body 100 and the second cleaning body 200 are integrally connected and held by the front and rear connecting members 83, 83 as shown in FIG. Are supported so as to be reciprocally movable in the lateral direction (the longitudinal direction of the sheave member 23b). Further, as shown in FIG. 22, the diffusion plate portion 81 is erected in a vertical posture along the vertical direction, and each plate 81 is provided with a guide hole 81h that matches the cross-sectional shape of the sheave member 23b. Each sheave member 23 is inserted into each guide hole 81h and is slidably guided.

  The scraper portion 82 contacts the inclined upper surface of the sheave member 23b that is inclined in the vertical direction, and removes adhering substances by sliding movement. The scraper portion 82 of the present embodiment has an inclined blade edge 82a that is inclined at a predetermined angle with respect to the moving direction, symmetrically across the diffusion plate portion 81, and is substantially U-shaped inclined blade edge 82a in plan view. , 82a. With such a shape, it is possible to remove the deposits to the left and right reciprocating movements without difficulty. Further, the scraper portion 82 is provided with ascending inclined surfaces 82s and 82s (see FIGS. 19 to 21) so as to maintain a mountain-shaped inclination angle when viewed from the front, and the ascending inclined surface 82s as it moves in the lateral direction. , 82s allows the deposits on the surface of each sheave member 23b to be scooped upward. The most projecting end portion 82e of the scraper portion 82 is configured to coincide with the bent ridge line of the sheave member 23b, so that the dust and dust accumulated in the bent portion of the sheave member 23b can be easily removed.

  Although the diffuser plate portion 81 and the scraper portion 82 can be separated from each other, if they are integrated as in the present embodiment, and particularly formed integrally with a synthetic resin material, they are easy to manufacture, cost, and maintainability. It is preferable because it is excellent. As shown in FIG. 16, at least one of the first cleaning body 100 and the second cleaning body 200 can be configured with only the diffusion plate portion 81 by omitting the scraper portion.

  Although the cleaning body drive device for driving the first cleaning body 100 and the second cleaning body 200 can be designed as appropriate, in this embodiment, as shown in FIGS. Accordingly, the first operation arm 86b, 86b that is alternately pulled, the first balance arm 187 that reciprocates, the first balance arm shaft 189, the first swing arm 188 that reciprocally rotates, and the like are connected to each other. The cleaning body 100 is configured to reciprocate in the lateral direction, and is linked to the second balance arm 287, the second balance arm shaft 289, and the first swing arm 188 that are connected to the first balance arm 187 by a link. The second cleaning body 200 is configured to reciprocate in the left and right lateral directions via an interlocking mechanism such as a second swing arm 288 connected by 300 and 300.

  That is, when the drive motor 85 is driven, the pair of operation cables 86b and 86b connected to the crank pin 86p are alternately pulled by the rotation of the crank arm 86, and the first balance arm 187 is reciprocally rotated. A first swing arm 188 reciprocally swings left and right with the one balance arm shaft 187 as a rotation center, and has a downward projecting portion 89 movably inserted into a long hole 181 of the first swing arm 188. The first cleaning body 100 is forcibly reciprocated in the horizontal direction. Since the crank pin 86p and the operation cable 86b are connected and held via the spring 86s and the plate 86t, an excessive load is not applied to the operation cable 86b. The drive motor 85 is preferably configured to automatically start driving in conjunction with a threshing operation, for example, a threshing clutch engagement operation. However, the drive motor 85 may be configured to start driving by an arbitrary switch without being interlocked.

  Further, the first balance arm 187 has a first connecting portion 185 projecting on the opposite side of the first swing arm 188 across the first balance arm shaft 189, and the second balance arm 287 also has the second balance arm shaft 289. A second connecting portion 285 protrudes on the opposite side of the second swing arm 288 across the first swing arm 288, the first swing arm 288, the second swing arm 288, and the first connecting portion 185 and the second connecting portion 285. Are connected by links 300 and 300, respectively. Among these cleaning body driving devices, some of them (in the illustrated example, the tip of the operation cable 86b, the first and second balance arms 187 and 287, the first and second balance arm shafts 189 and 289, and the first If the bases of the first and second swing arms 188 and 288 and the link 300) are provided in the space portion below the transfer shelf 22 and above the Kara wind tunnel 17, the dead space of the swing sorting shelf 20 parts is effective. And can be arranged and configured in a compact manner.

  Further, the distance from the first balance arm shaft 189 to the connection position of the link 300 of the first swing arm 188 is equal to the distance from the second balance arm shaft 289 to the connection position of the link 300 of the first connection portion 185. The distance to the connection position of the link 300 in the two swing arms 288 and the distance to the connection position of the link 300 in the second connection portion 285 are equal, and the latter w2 is longer than the former w1. As a result, the reciprocal swing of the first balance arm 187 and the first swing arm 188 is transmitted to the second balance arm 287 and the second swing arm 288 via the links 300 and 300, respectively. A second cleaning body 200 having a downward projecting portion 89 movably inserted into the long hole 281 of 288 is forcibly reciprocated in the left and right lateral directions. At this time, the first cleaning body 100 and the second cleaning body The reciprocating rocking speed of the second cleaning body 200 becomes faster than the reciprocating rocking speed of the first cleaning body 100.

  Therefore, a relatively small amount of threshing processed material on the first sheave 23 (that is, a cleaning action is relatively small) is relatively reciprocally oscillated at the portion of the handling cylinder 10 on the side where the cereal contact starts. Cleaning and diffusion are performed by the first cleaning body 100 having a low speed, and a relatively large amount of threshing processed material is generated on the first sheave 23 due to the rotation direction of the barrel 10 and the effect of the second reduction mechanism (that is, relatively In the part of the handling cylinder 10 on the side where the culm contact ends, which requires a strong cleaning action, cleaning and diffusion are performed by the second cleaning body 200 having a relatively fast reciprocating rocking speed. In addition, the cleaning efficiency can be improved, the threshing product on the first sheave 23 is diffused and leveled more widely, the clogging of the first sheave 23 is reduced, and the sieve selection efficiency of the first sheave 23 Improvement, and It is possible to improve the sorting performance of the whole by these. Furthermore, in the case of this embodiment, the 2nd cleaning from which the stroke of the 1st cleaning body 100 from which the threshing processed material to be cleaned becomes a relatively small amount is relatively short, and the threshing processed material to be cleaned becomes a relatively large amount. Since the stroke of the body 200 becomes relatively long, the cleaning efficiency and the diffusion efficiency of the threshing product on the first sheave 23 are further improved.

  Further, in the present embodiment, the adhering material on the surface of the sheave 23 is projected to the side diffusion plate portion 81s on the opposite side to the second cleaning body 200 side in the first cleaning body 100 so as to protrude on the opposite side to the second cleaning body 200 side. A scraper portion 82 to be removed is provided, and the second cleaning body 200 protrudes on the side diffusion plate portion 81 s on the opposite side to the first cleaning body 100 side, on the opposite side to the first cleaning body 100 side, and deposits on the surface of the sheave 23. Since the scraper portion 82 is provided to remove the threshing material, a wider range of the threshing product on the first sheave 23 can be diffused by the side diffusion plate portion 81s. The scrap remaining on the first sheave 23 can be scraped out by the scraper portion 82. Therefore, it becomes difficult to deposit and solidify the left side of the side diffusion plate portion 81s in the left and right direction, and the reciprocating oscillation of the cleaning bodies 100 and 200 is hindered by the accumulated solid material of the left side, or the sieve sorting ability is reduced. It becomes possible to prevent such a situation. From this point of view, as shown in FIG. 15, the scraper portion 82 is provided only on the outer side in the left-right direction of the side diffusion plate portion 81 s, and the scraper is provided on the inner side in the left-right direction of the side diffusion plate portion 81 s and the other diffusion plate portions 81. It is also preferable that the portion 82 is not provided. In this case, a large filtration area can be ensured without losing the cleaning effect and the diffusion effect excessively, and the loss can be reduced.

  The strokes of the reciprocating swing of the first cleaning body 100 and the second cleaning body 200 can be determined as appropriate. However, as shown in FIG. If it is configured to be smaller than the movement strokes s1, s2 (d1 <s1, d2 <s2), the reciprocating swing range of the adjacent diffusion plate portions 81 is adjacent or partly overlapped. This is preferable because the threshing product is less likely to stay between the reciprocating rocking ranges, and the cleaning efficiency and the diffusion efficiency of the threshing product on the first sheave 23 are further improved.

  The arrangement interval of the diffusing plate portion 81 is the same between the first cleaning body 100 and the second cleaning body 200, and can also be made different as shown in FIG. When the arrangement interval d2 of the diffusion plate portion 81 in the second cleaning body 200 in which the amount of threshing target to be cleaned is relatively larger than the arrangement interval d1 of the diffusion plate portion 81 of the first cleaning body 100 becomes a configuration. This is preferable because the cleaning efficiency and the diffusion efficiency of the threshing product on the first sheave 23 are further improved.

  In addition, the cycle of the reciprocating swing of the first cleaning body 100 and the second cleaning body 200 may be independent without synchronizing with other mechanisms, but can be synchronized. When the movement of the two cleaning bodies 200 toward the first cleaning body 100 is synchronized, the second cleaning body 200 adjusts when the threshing processed material on the sheave 23 is moved backward by the first sheave 23 swinging back and forth. Since the processed threshing product on the first sheave 23 can be transferred from the larger side to the smaller side, the processed product on the first sheave 23 can be more efficiently diffused.

  On the other hand, in this embodiment, also in the 2nd sheave 24, the 1st cleaning body 100 and the 2nd cleaning body 200 similar to the 1st sheave 23 are provided, and the 1st cleaning body 100 in the 2nd sheave 24 is The first balance arm 487 is reciprocated in the left-right direction by the reciprocating swing of the first swing arm 488 by the reciprocating rotation of the first balance arm 487, and the second cleaning body 200 in the second sheave 24 is the second balance. The second swing arm 588 is swung back and forth in the left-right direction by the reciprocating swing of the arm 587. The first balance arm 487 for driving the first cleaning body 100 of the second sheave 24 and the second balance arm 187 for driving the first cleaning body 100 of the first sheave 23 are the first parallel links. And a second balance arm 587 for driving the second cleaning body 200 of the second sheave 24, and a second balance arm 287 for driving the second cleaning body 200 of the first sheave 23. Are connected by second parallel links 602 and 602. As a result, the first cleaning body 100 and the second cleaning body 200 of the second sheave 24 are reciprocally swung in the same direction in conjunction with the first cleaning body 100 and the second cleaning body 200 of the first sheave 23 ( They can also be connected by a cross link, in which case the front and rear cleaning bodies linked are reciprocally swung in the opposite direction). Therefore, the same effects as the first sheave 23 are exhibited in the second sheave 24.

(Other)
(A) Although the said example has provided the 1st cleaning body 100 and the 2nd cleaning body 200 in both the 1st sheave 23 and the 2nd sheave 24, either, like the example shown in FIG.15 and FIG.16, Only the first sheave 23 may be provided with the first cleaning body 100 and the second cleaning body 200, and the other sheave 24 may be provided with no cleaning tool, or may be provided with a single cleaning tool.

  (B) The drive device of the 1st cleaning body 100 and the 2nd cleaning body 200 can also be comprised independently. Moreover, the drive device of the cleaning bodies 100 and 200 of the first sheave 23 and the drive device of the cleaning bodies 100 and 200 of the second sheave 24 can be configured individually and independently. Furthermore, in the drive device of the above example, the first and second cleaning bodies 100 and 200 are continuously swung, but may be configured to be intermittent.

  (C) In the above example, the first cleaning body 100 and the second cleaning body 200 are reciprocally swung in the same direction, but as shown in FIG. 24, the first cleaning body 100 and the second cleaning body The first cleaning body 100 and the second cleaning body 200 can be configured to reciprocate in the left and right directions by connecting the body 200 with the cross links 310 and 310, for example. In this case, there is an advantage that the generated vibrations can be canceled each other, noise and vibration can be reduced, and scooping can be favorably performed with good balance.

  (D) The threshing apparatus 3 of the above example is an example in which the second processing chamber 40 is provided, but a form that does not have a second reduction mechanism such as the second processing chamber 40 can also be adopted.

  (E) As shown in FIGS. 25 to 29, at least the handling chamber 11 in the threshing device 3 is divided into two in the vertical direction, and the upper portion 11 </ b> T of the device upper portion 11 </ b> B is pivoted on the side of the handling chamber 11. The apparatus upper portion 11T is pivotally supported by the apparatus upper portion 11T, and an intermediate partition wall 11K that divides the apparatus upper portion 11T in the front and rear directions is provided in the apparatus upper portion 11T. It is also possible to adopt a configuration in which the handling chamber 11 is configured at the front side portion, and the stab particle collection chamber 11E is provided between the intermediate partition wall 11K and the rear partition wall 11L. Thereby, when the apparatus upper part 11T is rotated upward, the handling cylinder 10 and the intermediate partition wall 11K are also rotated upward and the inside is opened, so that the maintenance performance is excellent.

  In this embodiment, as shown in the illustrated example, the stabbed grain recovery chamber 11E in the lower part 11B of the apparatus is provided with a culm support 11M having a shape along the outer periphery of the inclined tooth-handling 10c, and below the stabbed grain recovery chamber 11E. A configuration in which the cereal is supported toward the barrel 10 is preferable because the action of knocking off the stabbed grains by the inclined teeth 10c of the stabbed grain collection chamber 11E is promoted. Further, as shown in the example, when the through hole 15H is provided at the terminal end of the handling net 15 at the lower front portion of the intermediate partition wall 11K and the above-mentioned cereal support 11M is provided at the rear, the grains generated in the handling chamber 11, All or most of the waste is discharged from the through-hole 15H onto the swing sorting shelf 20, making it difficult for the waste to be fed into the stab particle collection chamber 11E, and improving the stab particle knockout efficiency in the stab particle recovery chamber 11E. Therefore, it is preferable.

  The present invention can be applied to a threshing apparatus such as a combine.
