JP 2002-112618 A Japanese Patent Laid-Open No. 11-75504

  By the way, the threshing apparatus described in Patent Document 1 has a configuration in which the handling chamber communicates with the processing chamber as shown in FIG. Thus, in the threshing apparatus provided with the processing chamber, in order to put the workpiece into the processing chamber, the space between the processing chamber and the handling chamber must be opened. However, in the configuration of Patent Document 1, due to the rotational force of the processing cylinder, an object to be processed in the processing chamber sometimes jumps out to the handling chamber side without being processed. The object to be processed that has jumped out of the processing chamber falls untreated. For this reason, there existed a problem that the efficiency of the whole threshing apparatus will fall.

  In this respect, Patent Document 2 discloses a configuration in which a partition plate is provided upward from the left end portion of the crimp net and the lower left side of the processing cylinder is covered by the partition plate. Since this partition plate is disposed between the handling cylinder and the processing cylinder, it is considered that there is an effect of preventing the workpiece from jumping out from the processing cylinder to the handling cylinder.

  However, when the partition plate is provided as in Patent Document 2, the space between the handling chamber and the processing chamber is narrowed, and as a result, there is a problem that the object to be processed is not smoothly put into the processing chamber from the handling chamber. As a result, there is a case where the object to be processed generated in the handling cylinder falls without being put into the processing chamber, resulting in a decrease in processing efficiency.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a threshing apparatus that prevents the workpiece from jumping out of the processing chamber and improves the processing efficiency.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the viewpoint of this invention, the threshing apparatus of the following structures is provided. That is, the threshing apparatus includes a handling cylinder, a processing cylinder, a workpiece guide plate, and a partition plate. The said handling cylinder rotates in the upper handle type centering | focusing on the rotating shaft set substantially horizontal, and has a some teeth on the outer periphery. The processing cylinder rotates about a rotation axis set substantially parallel to the rotation axis of the handling cylinder and lower than the rotation axis of the handling cylinder, and has a plurality of processing teeth on the outer periphery. The processing object guide plate guides the processing object generated in the handling cylinder toward the processing cylinder. The partition plate is disposed between the handling cylinder and the processing cylinder. Further, the upper end of the partition plate is set at a position higher than the upper end of the rotation locus of the tip of the processing tooth. The workpiece guide plate is disposed such that a surface on the side for guiding the workpiece or an extended surface thereof passes above the upper end of the partition plate.

  In this way, since the partition plate is provided between the handling cylinder and the processing cylinder and the upper end of the partition plate is positioned higher than the processing teeth, the object to be processed jumps from the processing cylinder toward the processing cylinder. Can be prevented. In addition, when the upper end of the partition plate is provided at a high position in this way, the path of the object to be processed from the handling cylinder to the process cylinder becomes narrow, but the object to be processed is processed by the object guide plate as described above. Since it is configured to guide, the object to be processed can be smoothly put into the handling cylinder. With the above configuration, an object to be processed generated in the handling cylinder can be reliably processed in the processing cylinder, so that the efficiency of the entire threshing apparatus can be improved.

  Said threshing apparatus WHEREIN: It is preferable that the said partition plate has faced diagonally downward at least one part of the surface which faces the said process cylinder side.

  By tilting the partition plate in this manner, it is possible to more effectively prevent the workpiece from jumping out of the processing cylinder due to the “turning back” effect.

In the threshing apparatus, near the lower end of the partition plate, the provided cutting teeth to finely cut the object to be processed, said cutting teeth, and a benzalkonium be passed between the processing teeth of the processing cylinder preferable.

  By providing the cutting teeth in this way, it is possible to cut the workpiece finely and improve the processing efficiency. In addition, since the incisors are arranged at the lower end of the partition plate, even if the object to be processed, which has been cut by the incisors and becomes finer, scatters, the object to be processed will scatter to the handling cylinder side. Can be prevented by the partition plate.

Side surface sectional drawing which shows the inside of a threshing apparatus. Front sectional drawing of a threshing apparatus. Plan sectional drawing of a threshing apparatus. FIG.

  Next, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 to FIG. 4, a culm transport mechanism 11 is disposed on the side surface of the threshing device 10. The corn straw transport mechanism 11 mainly includes a corn straw transport chain 12 and a pressing member 13 (FIG. 3).

  As shown in FIG. 1, the cereal haul transport chain 12 is configured in an endless annular shape and is configured to be circulated and driven by the rotation of the sprocket. As shown in FIG. 3, the pressing member 13 is configured to be pressed against the upper surface of the cereal conveyance chain 12. Thereby, as shown in FIG. 3, the root portion of the culm 14 can be sandwiched and held between the upper surface of the culm transport chain 12 and the pressing member 13. And it is the structure which conveys the said culm 14 in a predetermined direction by circulatingly driving the culm conveyance chain 12 in this state. In the following description, the direction in which the culm is transported by the culm transport mechanism 11 is simply referred to as the transport direction.

  In the threshing apparatus 10, a handling room 15 is formed which is a space for threshing the cereal. A handling cylinder 16 that threshs by rotating is disposed in the handling chamber 15. As the cereal basket 14 is transported by the cereal basket transport mechanism 11, the tip 14 a of the cereal basket 14 passes through the inside of the handling chamber 15. At this time, the threshing of the cereal basket 14 is performed by the rotating handling cylinder 16. As shown in FIG. 4, the cereal carrying chain 12 is disposed substantially parallel to the rotating shaft 17 of the handling cylinder 16 in a plan view. Therefore, the cereal basket 14 is conveyed along the rotating shaft 17 of the handling cylinder 16.

  After the threshing by the handling cylinder 16 has been completed, the cereal meal (removal) is delivered to the retreat transportation mechanism 18 (FIGS. 1 and 4) at the downstream end of the cereal transportation mechanism 11. As shown in FIG. 4, the waste transport mechanism 18 has a structure in which a waste transport chain 19 and a locking transport belt 20 are provided in parallel. The waste transport chain 19 is configured as an endless annular chain, and is configured to transport the root portion of the waste with its lower surface by being driven to circulate. The latching and conveying belt 20 is an endless annular belt in which tines (not shown) are arranged at regular intervals, and by circulating and driving the latching and conveying belt 20, the tip portion of the cereal is locked by the tine. It is the structure to convey.

  As shown in FIG. 1, a waste disposal unit 21 is disposed below the waste transport mechanism 18. The waste disposal unit 21 includes a waste cutter for finely cutting the waste, a diffusion device for discharging the cut waste to the outside of the machine, and the like. The waste transported by the waste transport mechanism 18 is sequentially put into the waste processing unit 21, cut into pieces, and then uniformly discharged to the field.

  Next, the configuration for threshing the cereal meal will be described in detail.

  The handling cylinder 16 is configured by a metal plate as a hollow cylinder having a substantially octagonal columnar shape, and a rotation shaft 17 thereof is disposed substantially horizontally along the apparatus front-rear direction. A plurality of teeth 22 are provided on the outer periphery of the barrel 16 so as to protrude outward.

  As shown in FIG. 2 and the like, a plurality of teeth 22 are provided side by side in a direction parallel to the rotation shaft 17 of the barrel 16. As shown in FIG. 5, the teeth 22 are formed in a flat shape so as to form a plane parallel to the direction in which the teeth 22 are arranged. Moreover, as shown in FIG. 5, the front-end | tip part of the tooth-handling 22 is comprised by the substantially V shape where a width | variety narrows toward a front-end | tip. Therefore, a V-shaped groove 23 whose width increases toward the tip is formed between adjacent teeth 22. In addition, a round (or polygonal) punch hole 24 is formed in the back of the V-shaped groove 23 so as to communicate with the V-shaped groove 23.

  The pestle 14 conveyed through the handling chamber 15 by the cereal conveying mechanism 11 is fitted into a portion between the tooth handling 22 and the tooth handling 22 (V-shaped groove 23 and punched hole 24). By rotating the handling cylinder 16 in this state, the cereal basket 14 is handled toward the tip 14a. Thereby, only the portion of the ear is taken from the cereal basket 14. In addition, the part of the ear taken from the cereal cocoon 14 in this way is referred to as an ear piece.

  In addition, the handling cylinder 16 of this embodiment is comprised so that it may rotate to a top handle type. That is, as shown in FIG. 3, the culm 14 is handled upward, and the tip 14 a of the culm 14 is configured to pass above the handling cylinder 16.

  As shown in FIG. 2, a supply port 25 is formed at the upstream end of the handling chamber 15 in the transport direction. The tip 14 a of the corn straw 14 conveyed by the corn straw conveying mechanism 11 is introduced into the handling chamber 15 through the supply port 25. As shown in FIG. 2, a tip guide plate 26 connected to the lower edge portion of the supply port 25 is disposed upstream of the supply port 25 in the transport direction. The portion of the tip 14 a of the grain pod 14 is guided to the supply port 25 by the upper surface of the tip guide plate 26. With this configuration, the tip 14 a of the grain pod 14 can be appropriately supplied to the handling chamber 15.

  Moreover, the threshing apparatus 10 of this embodiment is provided with a backflow prevention member 50 that closes the supply port 25 from the inside of the handling chamber 15. Thus, by closing the supply port 25 with the backflow prevention member 50, it is possible to prevent the cutting of spikes from jumping out of the handling chamber 15 through the supply port 25, and to improve the efficiency of the threshing device 10. In addition, since this backflow prevention member 50 is comprised from the rubber plate, the tip 14a of the grain pod 14 can advance so that the backflow prevention member 50 may be pushed away.

  Moreover, in this embodiment, as shown in FIG. 3 etc., the culm pressing member 28 is arrange | positioned between the culm conveyance mechanism 11 and the handling cylinder 16. FIG. The corn straw holding member 28 is a round pipe disposed substantially along the conveying direction of the corn straw 14. As shown in FIG. 3, the culm pressing member 28 is disposed so as to come into contact with the culm 14 between the culm conveying mechanism 11 and the handling cylinder 16 from above. Thereby, since the grain basket 14 can be pressed down with respect to the handling cylinder 16, it can prevent the said grain basket 14 from floating from the handling cylinder 16, and can perform threshing reliably.

  Next, the processing of the tip (cutting of ears) removed from the grain basket 14 by the rotation of the handling cylinder 16 will be described in detail. In the handling chamber 15, grains and sawdust are generated in addition to the cutting of the ears due to the rotation of the handling cylinder 16. These mixtures are hereinafter referred to as workpieces.

  The object to be processed generated by the rotation of the handling cylinder 16 is discharged toward the downstream side in the rotation direction of the handling cylinder 16 by the rotation of the handling cylinder 16. In the handling chamber 15, at the position where the object to be processed is dropped, a spike processing device 29 is arranged. The object to be processed discharged from the handling cylinder 16 is put into the ear piece processing device 29 and processed by the ear piece processing device 29 to be singulated (the grain is removed from the branch raft).

  As shown in FIGS. 3 and 4, the ear piece processing device 29 includes a processing cylinder 30 and a receiving net 31.

  The processing cylinder 30 is formed in a substantially rectangular tube shape, and is configured to be rotationally driven with the axis thereof as a rotation shaft 32. The rotating shaft 32 of the processing cylinder 30 is disposed so as to be substantially parallel to the rotating shaft 17 of the handling cylinder 16. In this embodiment, as shown by an arrow in FIG. 3, the handling cylinder 16 and the processing cylinder 30 are rotationally driven in the same direction. The processing cylinder 30 has a plurality of processing teeth 33 protruding outward. As shown in FIG. 4, the plurality of processing teeth 33 are arranged side by side along the axial direction of the processing cylinder 30.

  The receiving net 31 is provided so as to cover the lower half of the processing cylinder 30. As shown in FIG. 3, the receiving net 31 is formed along the locus of the tip of the rotating processing tooth 33 when viewed in the axial direction of the processing cylinder 30.

  With this configuration, the workpiece introduced from the handling cylinder 16 into the earbrush processing device 29 is subjected to a crushing action between the rotating processing teeth 33 and the receiving net 31, and single grain formation is promoted. The The shed grain passes through the receiving net 31 and falls downward. In addition, cutting teeth 49 are formed at the downstream end of the receiving net 31 in the rotation direction of the processing cylinder 30. A plurality of the cutting teeth 49 are formed side by side in the axial direction of the processing cylinder 30. And it is comprised so that the process tooth | gear 33 may pass between the incisors 49 by the process drum 30 rotating. Thereby, the sawdust etc. which were thrown into the ear piece processing apparatus 29 are cut | judged finely. Finely cut sawdust passes through the receiving net 31 and falls downward.

  The rotating shaft 32 of the processing cylinder 30 is disposed at a position lower than the rotating shaft 17 of the handling cylinder 16. As a result, the object to be processed falling from the handling cylinder 16 can be received by the cutting edge processing device 29.

  However, if the workpieces are simply released from the handling cylinder 16, some of the workpieces may fly along an unexpected trajectory and may not be received by the cutting edge processing device 29. For example, a case where the object to be processed discharged from the handling cylinder 16 collides with the wall surface 54 (FIG. 3) constituting the side surface of the casing of the handling chamber 15 and bounces back and returns to the handling cylinder 16 side can be considered. In this way, when the object to be processed returns to the handling cylinder 16 side, the object to be processed is not introduced into the earbrush processing apparatus 29, but between the ear cutting processing apparatus 29 and the handling cylinder 16. Fall through. Thus, when the ratio of the to-be-processed object which falls without being thrown into the spike cutting apparatus 29 increases, the efficiency of the whole threshing apparatus 10 will fall.

  Therefore, the workpiece guide plate 35 is disposed on the upstream side of the processing cylinder 16 in the rotational direction of the processing cylinder 30 and above the processing cylinder 30. The workpiece guide plate 35 is disposed at a position where the workpiece discharged from the handling cylinder 16 collides. Therefore, the object to be processed generated in the handling cylinder 16 is discharged to the downstream side in the rotation direction of the handling cylinder 16 by the momentum of the handling cylinder 16, and then collides with the object guide plate 35.

  The workpiece guide plate 35 is disposed so that the surface facing the treatment cylinder 16 faces obliquely downward. Accordingly, the object to be processed discharged from the handling cylinder 16 collides with the surface of the object guide plate 35 facing diagonally downward, and the lower end part of the object guide plate 35 faces (diagonally downward). Guided towards. Since the workpiece guide plate 35 is arranged in this way, the workpiece to be processed discharged from the handling cylinder 16 can be guided to the processing drum 30 of the spike processing device 29 by the workpiece guide plate 35. it can.

  In addition, a plurality of adjusting plates 56 are attached to the workpiece guide plate 35 on the surface facing the handling cylinder 16 (the surface on the side for guiding the workpiece). The adjustment plate 56 is provided so as to protrude in a direction substantially orthogonal to the surface of the workpiece guide plate 35 facing the handle 16 side. The plurality of adjustment plates 56 are arranged side by side in a direction parallel to the rotation shaft 32 of the processing cylinder 30 (the left-right direction in FIG. 4). Further, each adjustment plate 56 is disposed so as to be inclined with respect to a direction parallel to the rotation shaft 32 of the processing cylinder 30.

  With the above configuration, the workpiece that has jumped out of the handling cylinder 16 is guided in an oblique direction with respect to the axial direction of the processing cylinder 30 by the adjustment plate 56 when colliding with the processing object guide plate 35, and It is introduced into the cut processing device 29. In this way, by guiding the object to be processed by the adjusting plate 56, the position where the object to be processed is inserted into the ear-break processing device 29 can be adjusted to some extent in the axial direction of the processing cylinder 30. Thereby, it can prevent that a to-be-processed object collects and is supplied to the specific location of the processing cylinder 30, and can adjust so that the distribution of the axial direction of the to-be-processed object supplied to the processing cylinder 30 may be made uniform. . Therefore, it is possible to effectively use the cutting end processing device 29 in the axial direction of the processing cylinder 30.

  Next, the sorting device 36 will be described.

  The sorting device 36 is disposed below the handling cylinder 16 and the ear piece processing device 29. As described above, the object to be processed generated in the handling cylinder 16 is processed by the cutting edge processing device 29 and falls through the receiving net 31. A fallen object (a mixture of grains, swarf, ears, etc.) falling from the receiving net 31 is referred to as an object to be selected in the following description. The object to be sorted that has fallen from the receiving net 31 is input to the sorting device 36.

  As shown in FIG. 2, the sorting device 36 includes a swing sorting unit 37 and a wind sorting unit 38.

  The swing sorting unit 37 includes a chaff sheave 39. The object to be sorted that has fallen from the receiving net 31 of the ear piece processing device 29 is first received by the chaff sheave 39. The chaff sheave 39 is configured by arranging a plurality of chaff fins 40 horizontally arranged in the left-right direction of the apparatus in the conveying direction of the cereal basket 14. The swing sorting unit 37 is configured to be able to reciprocally swing the chaff sheave 39 in the transport direction. That is, by reciprocatingly swinging the chaff sheave 39, heavy and small items to be sorted such as grains fall down between the chaff fins 40, and light and large items to be sorted such as sawdust are caught on the chaff fins 40. Remain.

  Each chaff fin 40 is arranged so that the upper surface thereof faces obliquely upstream in the transport direction. As a result, by reciprocatingly swinging the entire chaff sheave 39, the object to be sorted is transported toward the downstream side in the transport direction while being swing-sorted. Most of the grains fall until reaching the rear end of the chaff sheave 39, and only a piece of spikes and shavings remain on the chaff sheave 39.

  Next, the wind sorting unit 38 will be described. The wind sorting unit 38 includes a tang fan 41 and a grain sieve 42.

  The grain sheave 42 is configured as a mesh press or a crimp net, and is disposed below the chaff sheave 39. A first conveyor 43 configured as a screw conveyor is disposed below the grain sheave 42. Due to the rough selection of the chaff sheave 39, the heavy and small objects to be sorted (grains, etc.) that have fallen from the chaff sheave 39 fall on the grain sheave 42.

  The red fan 41 is configured to generate a sorting air that is directed downstream in the conveying direction and to apply the sorting air to the glensy sheave 42 from below.

  With the above configuration, the sorting wind generated by the red pepper fan 41 is applied to the sorting object that has fallen on the grain sieve 42. A heavy specific gravity that falls almost vertically regardless of the sorting wind, that is, a grain, is called the first thing. The first thing is introduced into the first conveyor 43, and the other lighter specific gravity is blown off toward the downstream side in the transport direction.

  The first thing (grain) introduced into the first conveyor 43 is conveyed by the first conveyor 43 and stored, for example, in a Glen tank (not shown). As described above, the grain can be selected and extracted from the selection object.

  A second conveyor 44 configured as a screw conveyor is disposed below the downstream side end portions of the chaff sheave 39 and the Glen sheave 42.

  Spikes, scraps and the like remaining on the chaff sheave 39 are transported toward the downstream side in the transport direction by the reciprocating swing of the chaff sheave 39 and fall onto the second conveyor 44. In addition, among the objects to be processed that have fallen on the grain sieve 42, cuts of ears, scraps, etc. blown off by the sorting wind of the Kara fan 41 also fall on the second conveyor 44. The wind sorting unit 38 has a blower fan 45 that applies an upward wind toward the downstream side in the transport direction with respect to the sorting object falling on the second conveyor 44.

  Of the items to be sorted that fall on the second conveyor 44, the ears with grains and the like are relatively heavy, so they fall and are introduced into the second conveyor 44 regardless of the wind of the blower fan 45. On the other hand, swarf and the like without grain are blown off by the wind of the blower fan 45 and discharged out of the apparatus from a not-shown culm outlet.

  Ears with grain are worth collecting because there is room for reprocessing and taking out the grain. Such an object to be reprocessed is referred to as a second object. The second product sorted by the wind sorting unit 38 and introduced into the second conveyor 44 is conveyed by the second conveyor 44 and supplied to the end of the second reduction conveyor 46.

  The second reduction conveyor 46 is a screw conveyor disposed substantially in the vertical direction, and is configured to convey the second item to a position higher than the ear-break processing device 29. The second product conveyed by the second reduction conveyor 46 is discharged from the discharge side end 47 of the second reduction conveyor 46. As shown in FIG. 4, a second guide passage 48 is connected to the discharge side end portion 47. The second guide passage 48 communicates with the spike breakage treatment device 29. Therefore, the second product discharged from the second reduction conveyor 46 is fed into the spike breaker 29 via the second guide passage 48. With the above configuration, the second item sorted by the sorting device 36 can be reprocessed by the ear-break processing device 29.

  Next, a characteristic configuration of the present embodiment will be described.

  As described above, in the conventional threshing apparatus, an object to be processed in the ear cutting processing apparatus sometimes jumps out to the handling cylinder side due to the rotational force of the processing cylinder. In particular, the threshing apparatus 10 of the present embodiment has a configuration in which the processing cylinder 30 rotates in the same direction as the handling cylinder 16, so that the downstream end of the receiving net 31 in the rotation direction of the processing cylinder 30 corresponds to the handling cylinder 16. Facing the side. For this reason, there exists a situation that a to-be-processed object jumps out toward the handling cylinder 16 from the terminal end of the receiving net 31.

  Therefore, the threshing apparatus 10 of this embodiment is provided with a partition plate 34 between the handling cylinder 16 and the processing cylinder 30.

  This partition plate 34 is comprised from the non-porous metal plate, and a to-be-processed object cannot pass this partition plate. As shown in FIG. 3, when viewed from a direction orthogonal to the rotation axis 32 of the processing cylinder 30, the partition plate 34 blocks a straight line connecting the rotation axis 17 of the handling cylinder 16 and the rotation axis 32 of the processing cylinder 30. Is arranged. As shown in FIG. 4, the partition plate 34 is provided so as to face the entire length of the processing cylinder 30 in the direction of the rotation axis 32.

  Further, the partition plate 34 is formed by bending a metal plate, and is disposed substantially along the rotation locus of the tip of the processing tooth 33 when viewed in the direction of the rotation shaft 32 of the processing cylinder 30 as shown in FIG. It is configured to be. Thereby, the partition plate 34 covers a part of the outer periphery of the processing cylinder 30. Further, the lower end portion of the partition plate 34 is disposed close to the end of the receiving net 31 (the end portion on the downstream side in the rotation direction of the processing cylinder 30).

  As described above, by arranging the partition plate 34 between the handling cylinder 16 and the processing cylinder 30 so as to cover a part of the outer periphery of the processing cylinder 30, the object to be processed in the cutting edge processing device 29 is It is possible to prevent the processing cylinder 30 from jumping out toward the handling cylinder 16 due to the rotational momentum. Thereby, the processing efficiency of the cutting-out processing apparatus 29 can be improved.

  In the present embodiment, as shown in FIG. 3, the upper end of the partition plate 34 is set to a position higher than the upper end of the rotation locus of the tip of the processing tooth 33. As described above, since the upper end of the partition plate 34 is provided at a position higher than the processing teeth 33, the object to be processed in the earbrush processing device 29 jumps over the partition plate 34 and jumps to the handling cylinder 16 side. It has become difficult.

  Further, as described above, the partition plate 34 is bent along the rotation locus of the tip of the processing tooth 33, and the upper end of the partition plate 34 is set at a position higher than the rotation locus. Is configured to cover the processing cylinder 30 obliquely from above. Accordingly, at least a part of the surface of the partition plate 34 facing the processing cylinder 30 is directed obliquely downward. Thus, by arranging the partition plate 34 at an angle, it is possible to satisfactorily prevent the object to be processed in the earbrush processing device 29 from jumping out toward the barrel 16 due to the effect of “returning”. .

  Further, as described above, the lower end of the partition plate 34 is disposed close to the end of the receiving net 31. Further, as described above, the incisor 49 is formed at the end of the receiving net 31 (therefore, it can be said that the incisor 49 is disposed in the vicinity of the lower end portion of the partition plate 34). Since the workpiece is cut by the cutting teeth 49 and the rotating processing teeth 33, fine shavings are generated at the cutting teeth 49. The shavings generated in this way are likely to scatter due to the rotational momentum of the processing teeth 33. If the swarf scattered in this way is scattered to the barrel 16 side, the swarf adheres to the tip 14a of the cereal basket 14 and invites a decrease in threshing efficiency. In this regard, the threshing apparatus 10 according to the present embodiment has a configuration in which the partition plate 34 is disposed on the downstream side in the rotation direction of the processing cylinder 30 when viewed from the incisors 49. Therefore, even if fine swarf is generated and scattered by the incisor 49, it can be prevented that these are scattered to the handling cylinder 16 side.

  Moreover, in the threshing apparatus 10 of this embodiment, the above-mentioned workpiece guide plate 35 is disposed immediately above the partition plate 34. In other words, the workpiece guide plate 35 is disposed such that the surface facing the handling cylinder 16 (the surface on the side for guiding the workpiece) passes above the upper end of the partition plate 34. Therefore, the object to be processed discharged from the barrel 16 is guided by the object guide plate 35 so as to pass above the partition plate 34 and is introduced into the spike processing device 29.

  That is, the threshing apparatus 10 of this embodiment closes the space between the handling cylinder 16 and the processing cylinder 30 with the partition plate 34 and sets the upper end of the partition plate 34 at a high position. The passage toward is narrow. Therefore, if the workpiece guide plate 35 is not present, there may be a problem that the workpiece generated in the handling cylinder 16 does not enter the spike processing device 29 smoothly. In this respect, the threshing apparatus 10 according to the present embodiment is configured to guide the object to be processed by the object guide plate 35 as described above. You can be surely guided to.

  As described above, the threshing apparatus 10 of the present embodiment includes the handling cylinder 16, the processing cylinder 30, the workpiece guide plate 35, and the partition plate 34. The handling cylinder 16 rotates upwardly about a rotating shaft 17 set substantially horizontally, and has a plurality of teeth 22 on the outer periphery. The processing cylinder 30 rotates about a rotating shaft 32 set substantially parallel to the rotating shaft 17 of the handling cylinder 16 and at a position lower than the rotating shaft 17, and has a plurality of processing teeth 33 on the outer periphery. The workpiece guide plate 35 guides the workpiece generated in the handling cylinder 16 toward the processing cylinder 30. The partition plate 34 is disposed between the handling cylinder 16 and the processing cylinder 30. Further, the upper end of the partition plate 34 is set at a position higher than the upper end of the rotation locus of the tip of the processing tooth 33. The workpiece guide plate 35 is arranged so that the surface on the side for guiding the workpiece passes above the upper end of the partition plate 34.

  As described above, the partition plate 34 is provided between the handling cylinder 16 and the processing cylinder 30, and the upper end of the partition plate 34 is positioned higher than the processing teeth 33. Can be prevented from flying toward In addition, when the upper end of the partition plate 34 is provided at a high position in this way, the path of the workpiece to be processed from the handling cylinder 16 to the processing cylinder 30 becomes narrow. Since the configuration is such that the workpiece is guided, the workpiece can be smoothly put into the processing cylinder 30. With the above configuration, the object to be processed generated in the handling cylinder 16 can be reliably processed in the processing cylinder 30, so that the efficiency of the entire threshing apparatus 10 can be improved.

  Moreover, in the threshing apparatus 10 of this embodiment, the partition plate 34 is arrange | positioned so that the surface which faces the process cylinder 30 side may face diagonally downward.

  By making the partition plate 34 slant in this way, it is possible to more effectively prevent the object to be processed from jumping out of the processing cylinder 30 due to the “returning” effect.

  Further, in the threshing apparatus 10 of the present embodiment, an incisor 49 that passes between the processing teeth 33 of the processing cylinder 30 is provided in the vicinity of the lower end portion of the partition plate 34.

  By providing the cutting teeth 49 in this way, it is possible to cut the object to be processed finely and improve the processing efficiency. Further, since the cutting teeth 49 are arranged at the lower end portion of the partition plate 34, even if the object to be processed which is cut by the cutting teeth 49 and splattered scatters, the object to be processed scatters toward the handling cylinder 16 side. This can be prevented by the partition plate 34.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  The threshing apparatus of the present invention can be applied to various threshing apparatuses such as a stationary threshing apparatus, a threshing apparatus with a built-in harvester, and a threshing apparatus with a built-in combine.

  In the above embodiment, the partition plate 34 is bent. However, the partition plate 34 does not necessarily have to be bent. Further, FIG. 3 shows a partition plate 34 that is bent linearly in a cross section perpendicular to the rotating shaft 17 of the handling cylinder 16. However, the present invention is not limited to this. For example, the partition plate 34 may be curved in a curved line along the rotation locus of the processing teeth 33.

  Although the workpiece guide plate 35 has been described on the assumption that the surface on the side for guiding the workpiece passes above the upper end of the partition plate 34, the workpiece guide plate 35 is not necessarily disposed immediately above the partition plate 34. You don't have to. That is, even if the workpiece guide plate 35 is disposed at a position off the top of the partition plate 34, the extended surface of the surface that guides the workpiece is located above the upper end of the partition plate 34. What is necessary is just to arrange | position so that it may pass. By arranging the workpiece guide plate 35 in this way, the workpiece generated in the handling cylinder 16 can be guided so as to pass above the partition plate 34.
