JP 2002-112618 A

  In the threshing apparatus configured as in Patent Document 1, it is ideal that the entire amount of the processing object generated in the handling cylinder is processed in the processing chamber. However, it is difficult to put the entire amount of the processing object discharged from the handling cylinder into the processing chamber. In reality, a part of the processing object generated in the processing chamber is not put into the processing chamber. It falls between the handling cylinder and the processing cylinder. Since the object to be processed that has not been put into the processing chamber falls unprocessed, the processing efficiency of the entire apparatus is reduced.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a threshing apparatus with improved processing efficiency by reliably guiding an object to be processed generated in a handling cylinder to the processing cylinder. There is.

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, this threshing apparatus includes a handling cylinder, a processing cylinder, and a guide unit. 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 guide portion receives the workpiece generated on the handling cylinder on the upper surface thereof and guides the workpiece toward the processing cylinder.

  By providing the guide portion in this manner, the object to be processed generated in the handling cylinder can be received before being dropped untreated and guided to the processing cylinder. Thereby, since it can prevent that a to-be-processed object falls without being processed with a processing cylinder, the processing efficiency of a threshing apparatus can be improved.

  The threshing device is preferably configured as follows. That is, the guide part is arranged at a position higher than the outer periphery of the processing cylinder. Further, the upper surface of the guide portion is disposed obliquely so that the end on the processing cylinder side is positioned lower than the end on the handling cylinder side.

  In this way, by arranging the guide portion obliquely toward the processing cylinder, the object to be processed received on the upper surface of the guide section can be naturally guided toward the processing cylinder.

  The threshing device is preferably configured as follows. That is, this threshing device includes a partition plate disposed between the handling cylinder and the processing cylinder. The upper surface of the guide portion is arranged so that the end portion on the processing cylinder side is connected to the upper end portion of the partition plate.

  By providing the partition plate in this manner, the object to be processed is less likely to jump out from the processing cylinder toward the handling cylinder, so that the processing efficiency of the processing cylinder can be improved. In addition, when the partition plate is provided in this way, the passage of the workpiece to be processed from the handling cylinder to the processing cylinder becomes narrow. However, since the upper surface of the guide surface is arranged as described above, the guide is guided by the upper surface. The object to be processed can pass above the partition plate. Accordingly, the object to be processed can be reliably supplied to the processing cylinder.

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 is 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 manner, as shown by reference numeral 60 in FIG. 3, the workpiece discharged from the handling cylinder 16 is processed by the spike guide device 35 by the workpiece guide plate 35. 29 processing cylinders 30 can be guided.

  A partition plate 34 is disposed between the handling cylinder 16 and the processing cylinder 30. The partition plate 34 is formed by bending a non-porous metal plate. The lower end portion of the partition plate 34 is disposed close to the end of the receiving net 31. By providing the partition plate 34 in this way, it is possible to prevent an object to be processed in the spike cutting device 29 from jumping out toward the handling cylinder 16 due to the rotational force of the processing cylinder 30. Thereby, the processing efficiency of the cutting-out processing apparatus 29 can be improved.

  Note that the above-described workpiece guide plate 35 is disposed directly 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, as shown by reference numeral 60 in FIG. 3, the workpiece discharged from the handling cylinder 16 is guided by the workpiece guide plate 35 so as to pass above the partition plate 34, and is sent to the spike processing device 29. And introduced.

  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 by 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, the threshing apparatus 10 according to the present embodiment has a configuration in which an object to be processed discharged from the handling cylinder 16 is input to the cut-out processing apparatus 29 and processed.

  Here, if the object to be processed generated in the handling cylinder 16 appropriately collides with the object guide plate 35, the object to be processed is appropriately picked up as indicated by reference numeral 60 in FIG. The cut processing device 29 can be loaded.

  However, in reality, not all the objects to be processed generated in the handling cylinder 16 fly in such an ideal locus. For example, when an object to be processed generated in the handling cylinder 16 collides with a part other than the object guide plate 35, the object bouncs back in an unexpected direction as indicated by reference numeral 61 in FIG. Further, for example, when the moment of the workpiece generated in the handling cylinder 16 is insufficient, the workpiece may fall without colliding with the workpiece guide plate 35 as indicated by reference numeral 62 in FIG. When the workpieces do not fly along an ideal trajectory (for example, when the workpieces fly along a trajectory as indicated by reference numerals 61 and 62 in FIG. 3), a part of the workpieces enters the spike processing device 29. And cannot pass through between the treatment cylinder 30 and the treatment cylinder 16. Since the processing object that has fallen without being put into the spike breaker 29 is thrown into the sorting device 36 without being processed, it causes a reduction in the efficiency of the sorting device 36, and consequently the efficiency of the entire threshing device 10. Leading to a decline.

  In particular, in the threshing apparatus 10 of this embodiment, since the partition plate 34 is disposed between the processing cylinder 30 and the handling cylinder 16, the passage from the handling cylinder 16 to the processing cylinder 30 is narrow, It is difficult for the processed material to enter the spike cutting device 29. In other words, the object to be processed generated in the handling cylinder 16 must pass above the partition plate 34 in order to enter the cutting edge processing device 29. Therefore, when the workpiece generated in the handling cylinder 16 flies, for example, in a trajectory as indicated by reference numerals 61 and 62 in FIG. And cannot pass through between the treatment cylinder 30 and the treatment cylinder 16.

  Therefore, the threshing apparatus 10 according to the present embodiment is provided with a guide unit 63 that receives an object to be processed generated on the handling cylinder 16 on the upper surface and guides the processed object to the earbrow processing apparatus 29.

  The guide portion 63 is disposed between the handling cylinder 16 and the processing cylinder 30. More precisely, as shown in FIG. 3, when viewed in the direction of the rotation axis 32 of the processing cylinder 30, the vertical line passing through the center of the rotation axis 17 of the handling cylinder 16 and the rotation axis 32 of the processing cylinder 30. A guide part 63 is arranged between the vertical line passing through the center. The guide portion 63 is disposed upstream of the processing cylinder 30 in the rotation direction of the handling cylinder 16. Further, the guide portion 63 is disposed at a position lower than the upper end of the outer periphery of the handling cylinder 16 and higher than the upper end of the outer periphery of the processing cylinder 30. As described above, since the guide part 63 is disposed between the handling cylinder 16 and the processing cylinder 30, an object to be processed that falls between the handling cylinder 16 and the processing cylinder 30 can be guided to the guiding part. 63 can be received by the upper surface.

  In the present embodiment, the guide portion 63 is a single metal plate, and the upper surface thereof is formed to be substantially smooth to constitute the guide surface 63a. As shown in FIG. 3, when viewed in the direction of the rotation axis 32 of the processing cylinder 30, the guide surface 63 a of the guide portion 63 is disposed obliquely. More specifically, the guide surface 63a is inclined with respect to the horizontal plane so that the end of the guide surface 63a on the processing cylinder 30 side is lower than the end of the handling cylinder 16 side. Thus, since the guide surface 63a is disposed so as to be lowered on the processing cylinder 30 side, the object to be processed received by the guide surface 63a is naturally guided toward the processing cylinder 30.

  In addition, the guide portion 63 is disposed outside the rotation locus 64 at the tip of the tooth handling 22 so as not to interfere with the tooth handling 22. However, as shown in FIG. 3, the guide portion 63 is arranged such that the end portion of the guide surface 63 a on the side of the handle cylinder 16 is as close as possible to the rotation locus 64 of the handle 22. On the other hand, as shown in FIG. 3, the end of the guide surface 63 a on the processing cylinder 30 side is arranged so as to be connected to the upper end of the partition plate 34. Since the guide surface 63a is arranged in this way, the object to be processed guided by the guide surface 63a can pass above the partition plate 34. As a result, the object to be processed received by the guide surface 63a can be introduced into the spike breaker 29.

  As explained above, the threshing apparatus 10 of this embodiment includes the handling cylinder 16, the processing cylinder 30, and the guide unit 63. 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 guide unit 63 receives the object to be processed generated in the handling cylinder 16 on its upper surface (guide surface 63a) and guides it toward the processing cylinder 30.

  By providing the guide part 63 in this manner, the object to be processed generated in the handling cylinder 16 can be received before being dropped untreated and guided to the processing cylinder 30. Thereby, since it can prevent that a to-be-processed object falls without being processed with the processing cylinder 30, the processing efficiency of the threshing apparatus 10 can be improved.

  Moreover, the threshing apparatus 10 of this embodiment is comprised as follows. That is, the guide part 63 is disposed at a position higher than the outer periphery of the processing cylinder 30. Further, the upper surface (guide surface 63a) of the guide portion 63 is disposed obliquely so that the end portion on the processing cylinder 30 side is positioned lower than the end portion on the handling cylinder 16 side.

  In this way, by arranging the guide part 63 obliquely toward the processing cylinder 30, the workpiece received on the upper surface (guide surface 63 a) of the guide part 63 is naturally guided toward the processing cylinder 30. can do.

  Moreover, the threshing apparatus 10 of this embodiment is comprised as follows. That is, the threshing apparatus 10 includes a partition plate 34 disposed between the handling cylinder 16 and the processing cylinder 30. The end of the upper surface (guide surface 63 a) of the guide portion 63 on the processing cylinder 30 side is disposed so as to be connected to the upper end portion of the partition plate 34.

  By providing the partition plate 34 in this manner, it becomes difficult for the object to be processed to jump out from the processing cylinder 30 toward the handling cylinder 16, so that the processing efficiency of the processing cylinder 30 can be improved. In addition, when the partition plate 34 is provided in this way, the path of the workpiece to be processed from the handling cylinder 16 to the processing cylinder 30 becomes narrow. However, the guide surface 63a is arranged as described above, so that the guidance is performed. The workpiece guided by the surface 63a can pass above the partition plate 34. Accordingly, the object to be processed can be reliably supplied to the processing cylinder.

  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.

  The partition plate 34, the workpiece guide plate 35, and the like can be omitted.

  Although the guide part 63 was demonstrated as a metal plate, if the structure which can receive a to-be-processed object on the upper surface, the raw material and shape will not be specifically limited.

  Moreover, it is good also as a structure by which the guide part 63 and the partition plate 34 which are shown in FIG. 3 were integrally formed. Specifically, the guide part 63 can be formed by bending the upper end of the partition plate 34 toward the handling cylinder 16 side. According to this, the guide part 63 can be formed easily, and can be formed in a state where the guide part 63 is connected to the upper end part of the partition plate 34.

  Although the guide part 63 was demonstrated as arrange | positioning so that it might connect to the upper end of the partition plate 34, it is not restricted to this, The guide part 63 and the partition plate 34 may be spaced apart. That is, it is only necessary that the workpiece guided by the guide surface 63a can pass above the partition plate 34, so that the guide surface 63a only needs to be arranged so as to pass above the partition plate 34. However, they are not necessarily arranged so that both are connected.
