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

As in the threshing apparatus described in Patent Document 1, in a threshing apparatus provided with a processing chamber, in order to put an object to be processed from the handling cylinder into the processing chamber, the processing chamber and the handling cylinder should be opened. There must be. 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 may jump out to the handling cylinder side without being processed. For this reason, there existed a problem that the efficiency of the whole threshing apparatus will fall.

In this regard, 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 a partition plate is provided as in Patent Document 2, the space between the handling cylinder and the processing chamber is partially blocked, so that the object to be processed can be smoothly fed from the handling cylinder into the processing chamber. There is a problem that it will not be done. As described above, even if the partition plate is provided to prevent the processing object from jumping out of the processing chamber, the processing efficiency is lowered due to another reason that the processing material is not smoothly put into the processing chamber.

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 an aspect of the present invention, a threshing apparatus having the following configuration is provided. That is, the threshing apparatus includes a handling cylinder, a processing cylinder, a first guide unit, and a partition plate. The said handling cylinder rotates in the upper handle type centering on the axis set substantially horizontal, and has a plurality of teeth on the outer periphery. The processing cylinder rotates about an axis set at a position substantially parallel to the axis of the handling cylinder and lower than the axis of the handling cylinder, and has a plurality of processing teeth on the outer periphery. The first guide unit guides an object to be processed generated in the handling cylinder toward the processing cylinder by a lower surface. The partition plate is disposed between the handling cylinder and the processing cylinder. 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 first guide portion is disposed such that the lower surface 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 workpiece to be processed from the handling cylinder to the processing cylinder is narrowed, but the workpiece is guided by the first guide as described above. Since it is set as the structure which carries out, it can throw in the said to-be-processed object smoothly to a process 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.

In the above threshing apparatus, it is preferable that at least a part of the surface of the partition plate facing the processing cylinder side is directed obliquely downward.

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

In the above-mentioned threshing apparatus, it is preferable to provide an incisor that passes between the processing teeth of the processing cylinder in the vicinity of the lower end of the partition plate.

By providing the cutting teeth in this way, it is possible to cut the object to be processed 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.

In the above processing apparatus, it is preferable that the processing apparatus includes a spiral guide member that is disposed so as to face the peripheral surface of the processing cylinder and that is disposed so as to substantially follow a spiral centering on an axis of the processing cylinder.

By providing the spiral guide member in this way, the object to be processed in the processing apparatus can be conveyed along the axial direction of the processing cylinder. Thereby, large dust can be prevented from staying in the processing apparatus, and the processing efficiency of the processing apparatus can be improved.

Said threshing apparatus WHEREIN: The said helical guide member is arrange | positioned so that the said to-be-processed object in the said processing apparatus may be conveyed toward the conveyance direction downstream of the said corn flour by rotation of the said processing drum. Is preferred.

On the downstream side of the cereal conveyance direction, the processing capacity of the processing apparatus has a margin because the amount of the workpiece to be processed from the handling cylinder to the processing apparatus is small. Then, by conveying the to-be-processed object in a processing apparatus toward a downstream, the full length of a processing apparatus can be used effectively and the processing efficiency of the said processing apparatus can be improved.

The threshing device is preferably configured as follows. That is, a sorting device is arranged below the processing device. A throwing blade that rotates together with the processing drum is provided at an end of the processing drum, and a lower portion of the throwing blade is opened.

Thus, by opening the lower part at the end of the processing cylinder, dust or the like conveyed by the spiral guide member can be dropped from the processing apparatus to the sorting apparatus. Thereby, it can prevent that a big dust etc. stay in a processing apparatus forever. Moreover, since the throwing blade is provided, the dust falling from the processing device to the sorting device can be dispersed by the rotational force of the throwing blade. Thereby, since it can suppress that dust etc. harden | solidify and fall to a sorting device, it can suppress that a big catamari falls to a sorting device and reduces the efficiency of the said sorting device.

The threshing device is preferably configured as follows. That is, the sorting apparatus has a separator below the throwing blade that receives the workpiece and allows the grains contained in the workpiece to pass through. And this threshing apparatus is equipped with the discharge apparatus which discharges | emits the said to-be-processed object received with the said separator outside the apparatus.

Thus, the object to be processed dropped by the throwing blades is received by the separator to separate the grain, and swarf other than the grain can be discharged out of the machine.

The threshing device is preferably configured as follows. That is, the ceiling surface of the casing of the handling chamber has a separation portion that is separated from the rotation locus of the tip of the tooth handling as it proceeds downstream in the rotation direction of the handling drum. The first guide portion is disposed downstream of the starting position of the separation portion in the rotation direction of the handling cylinder. The processing cylinder is disposed downstream of the first guide portion in the rotation direction of the handling cylinder.

In this way, by forming the separation portion on the ceiling of the casing, a space is formed between the ceiling and the handling cylinder, so that the cereal can be separated from the outer periphery of the handling cylinder. Thereby, since the winding of the cereals with respect to a handling cylinder can be prevented, the rotational load of a handling cylinder can be reduced. The object to be processed generated in the handling cylinder is released into the space. However, if the object to be processed flies in a free path in the space, the object to be processed smoothly flows into the processing cylinder. There is a possibility not to enter. Therefore, by providing the first guide portion as described above, the object to be processed discharged into the space can be guided to the processing cylinder.

The threshing device is preferably configured as follows. That is, the first guide part is arranged at a position higher than the processing cylinder. And between the upper end of the said 1st guide part and the said ceiling surface is closed.

By arranging the first guide portion in this manner, the object to be processed discharged from the handling cylinder can be appropriately guided to the processing cylinder. In addition, since the space between the upper end of the first guide portion and the ceiling surface is closed, the object to be processed does not pass above the first guide portion. Therefore, it is possible to guide the object to be processed by the first guide unit without any exception.

The threshing device is preferably configured as follows. That is, on the lower surface of the first guide portion, a plurality of plate-like adjustment plates that are substantially orthogonal to the lower surface are arranged side by side in a direction substantially parallel to the axis of the processing cylinder. At least one of the adjustment plates is disposed obliquely with respect to a direction parallel to the axis of the processing cylinder.

By guiding the object to be processed by the adjusting plate arranged obliquely, the object to be processed can be dispersed in the axial direction of the processing cylinder. Thereby, it can prevent that a to-be-processed object gathers in one place, and is supplied to a processing cylinder, and can use a processing cylinder efficiently in an axial direction.

The above-mentioned threshing device preferably includes a second guide portion between the handling cylinder and the processing cylinder, which receives a workpiece generated on the handling cylinder on the upper surface and guides the processed object toward the processing cylinder.

By providing the second guide portion in this way, it is possible to prevent an unprocessed workpiece from falling through between the handling cylinder and the processing cylinder, and to receive and guide the workpiece to the processing cylinder. .

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

Thus, by disposing the second guide portion obliquely toward the processing cylinder, the object to be processed received on the upper surface of the second guide portion can be naturally guided toward the processing cylinder.

In the above-described threshing apparatus, it is preferable that the upper surface of the second guide portion is disposed so that an end portion on the processing cylinder side is connected to an upper end portion of the partition plate.

Thus, by providing the guide portion so as to be connected to the partition plate, it becomes difficult for the workpiece to jump out from the processing cylinder toward the handling cylinder, so that the processing efficiency of the processing cylinder can be improved.

The threshing device is preferably configured as follows. That is, this threshing device includes a sorting device, a second reduction mechanism, and a second guide passage. The sorting device sorts the workpieces processed by the processing device into at least a first item that does not require reprocessing and a second item that requires reprocessing. The second reduction mechanism conveys the second product sorted by the sorting device to above the processing device. The second guide passage introduces the second product discharged from the discharge port of the second reduction mechanism into the processing apparatus while guiding the second product in a direction along the axis of the processing cylinder.

By providing the second guide passage in this way, the second product discharged from the second product reduction mechanism can be dispersed in the direction parallel to the axis of the processing cylinder and introduced into the processing apparatus. Thereby, since the processing apparatus can be used uniformly in the axial direction, the processing efficiency of the processing apparatus can be improved.

In the above threshing apparatus, when viewed in the axial direction of the processing cylinder, the discharge port of the second reduction mechanism is disposed on the opposite side of the handling cylinder across the first guide portion. preferable.

By arranging the first guide part between the discharge port of the second reduction mechanism and the handling cylinder, the second guide discharged from the discharge port by the first guide part is scattered to the treatment cylinder side. Can be prevented.

The threshing device is preferably configured as follows. That is, on the surface of the first guide portion facing the discharge port side, a plurality of second adjustment plates that are substantially orthogonal to the first guide portion are arranged in a direction substantially parallel to the axis of the processing cylinder. ing. At least one of the second object adjusting plates is disposed obliquely with respect to a direction parallel to the axis of the processing cylinder.

In this way, by guiding the second object by the second object adjusting plate arranged obliquely with respect to the axis of the processing cylinder, the second object can be dispersed in the axial direction of the processing cylinder. Thereby, the processing cylinder can be efficiently used in the axial direction.

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the threshing apparatus 1 according to the present embodiment includes a main body 10 and a culm transport mechanism 11 provided on a side portion of the main body 10.

As shown in FIG. 3, the corn straw transport mechanism 11 includes a corn straw transport chain 12 and a pressing member 13. 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.

The root of the grain basket 14 is held between the upper surface of the grain transport chain 12 and the pressing member 13 (see FIG. 3). By circulatingly driving the culm transport chain 12 in this state, the culm transport mechanism 11 transports the culm 14 from the front side of the apparatus toward the rear of the apparatus. In the following description, the direction in which the culm 14 is transported by the culm transporting mechanism 11 is simply referred to as the corn straw transporting direction.

Inside the main body 10, a handling chamber 15, a sorting device 36, and a waste disposal unit 21 are mainly arranged.

The handling room 15 is a space for threshing the cereal basket 14. As shown in FIGS. 1 and 2, on the front side of the main body 10 (on the left side in FIGS. 1 and 2), there is a cereal throwing-in portion 25 for introducing the tip 14 a of the stalk 14 into the inside of the handling chamber 15. Is formed. The tip 14 a of the corn straw 14 transported by the corn straw transporting mechanism 11 is introduced into the inside of the handling chamber 15 through the grain candy input section 25. In the handling chamber 15, a handling cylinder 16 and a spear cutting device 29 are arranged.

The handling cylinder 16 has a cylindrical configuration in which its axis 17 is arranged in parallel with the front-rear direction (left-right direction in FIG. 2) of the threshing device 1, and a tooth handling 22 described later is provided around the circumference. ing. The handling cylinder 16 is driven to rotate about the axis 17. As shown in FIG. 4, the cereal conveyance chain 12 is disposed substantially parallel to the axis 17 of the handling cylinder 16 in a plan view. As a result, the culm transport mechanism 11 transports the culm 14 along the axis 17 of the handling cylinder 16. At this time, the portion of the tip 14a is removed from the grain pod 14 to be conveyed by the teeth 22 of the rotating handling cylinder 16. The portion of the tip 14a removed at this time is referred to as “ear piece”.

The remaining part of the grain pod 14 from which the part of the tip 14a has been removed by the rotation of the handling cylinder 16 is referred to as “exclusion”. The waste is delivered to the waste transport mechanism 18 (FIGS. 1 and 4) at the downstream end of the grain transport mechanism 11 in the transport direction.

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 basket 14 will be described in detail.

The handling cylinder 16 is formed of a metal plate as a hollow cylinder having a substantially octagonal columnar shape, and its axis 17 is arranged substantially horizontally along the apparatus front-rear direction (left-right direction in FIG. 2). 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 axis 17 of the barrel 16. As shown in FIG. 5, each tooth handling 22 is formed in a flat (plate-like) shape so as to constitute 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. Further, in the back of the V-shaped groove 23, a round (or polygonal) punch hole 24 is formed continuously to the V-shaped groove 23.

The main body 10 also has a ceiling plate 27 that constitutes the ceiling of the handling room 15. The lower surface of the ceiling plate 27 faces the outer peripheral surface of the handling cylinder 16. As shown in FIG. 3, when viewed in the direction of the axis 17 of the handling cylinder 16, the ceiling plate 27 is formed in an arc shape along the rotational locus of the tip of the tooth handling 22. Further, the ceiling plate 27 is disposed so as to be close to the rotation locus of the tip of the tooth handling 22.

The handling cylinder 16 of the present embodiment is configured to rotate in a top handling manner. 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. Thereby, the tip of the grain basket 14 passes between the tooth handling 22 and the lower surface of the ceiling plate 27.

With the above configuration, the tip 14a of the culm 14 transported by the culm transporting mechanism 11 passes through a narrow gap between the ceiling plate 27 and the tooth handling 22. At this time, the tip 14 a is fitted into the portion between the tooth handling teeth 22 (the V-shaped groove 23 and the punched hole 24) so as to be pressed against the lower surface of the ceiling plate 27. By rotating the handling cylinder 16 in this state, the grain pod 14 is handled toward the tip 14a, and the portion of the tip 14a is taken from the grain cocoon 14 to be cut off.

Further, the ceiling plate 27 is connected to the second ceiling plate 52 at an end portion 27a on the downstream side in the rotation direction of the handling cylinder 16. The second ceiling plate 52 constitutes the ceiling of the handling room 15. Further, the second ceiling plate 52 is spaced away from the rotation locus of the tooth handle 22 as it proceeds to the downstream side in the rotation direction of the handle cylinder 16 when viewed in a cross section orthogonal to the direction of the axis 17 of the handle cylinder 16. Has a part. Thereby, a space 53 is formed between the second ceiling plate 52 and the rotation trajectory of the tip of the tooth handling 22. In other words, with the end portion 27a of the ceiling plate 27 as a starting point, a space 53 is formed above the handling cylinder 16 on the downstream side in the rotation direction of the handling cylinder 16 with respect to the end portion 27a.

Thus, since the space 53 is formed above the handling cylinder 16 on the downstream side of the end portion 27 a of the ceiling plate 27, the cereal basket 14 extends from the outer periphery of the handling cylinder 16 on the downstream side of the end portion 27 a. You can leave. Thereby, as a result that the grain ridge 14 becomes difficult to wind around the handling cylinder 16, the load for rotationally driving the handling cylinder 16 can be reduced.

Next, a detailed description will be given of the processing of the tip (cut of head) removed from the cereal basket 14 by the rotation of the handling cylinder 16. In addition, in the handling chamber 15, due to the rotation of the handling cylinder 16, dust such as sawdust, grains, and the like are generated in addition to cutting of the ears. 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. As described above, in this embodiment, the space 53 is formed above the handling cylinder 16. Therefore, the object to be processed discharged from the handling cylinder 16 jumps out toward the space 53 and falls in the space 53 while drawing a predetermined locus. As shown in FIG. 3, a spike processing device 29 is disposed at the dropping position of the workpiece. As shown in FIG. 3 and FIG. 4, the ear piece processing device 29 includes a processing cylinder 30 and a receiving net 31.

The treatment cylinder 30 is formed in a substantially rectangular tube shape and is configured to be rotationally driven around its axis 32. The axis 32 of the processing cylinder 30 is disposed so as to be substantially parallel to the axis 17 of the handling cylinder 16. In the present embodiment, as shown by arrows 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 a direction parallel to the axis 32 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 distal end of the rotating processing tooth 33 when viewed in the direction of the axis 32 of the processing cylinder 30.

With this configuration, the object to be processed generated in the handling cylinder 16 is introduced into the spike processing device 29. This object to be processed is subjected to a demulsifying action between the rotating processing teeth 33 and the receiving net 31, and single grain formation (removal of grains) is promoted. The shed grain passes through the receiving net 31 and falls downward. Further, an incision 49 is formed at the end of the receiving net 31. 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. 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.

Note that a suction fan (discharge device) 51 (FIG. 6) for sucking fine dust generated in the earbrush processing device 29 or the like and discharging it to the outside of the machine is downstream of the earbrowth processing device 29 in the grain haul conveyance direction. Adjacent to the side.

Next, the sorting device 36 will be described with reference to FIG.

The sorting device 36 is disposed below the handling cylinder 16 and the ear piece processing device 29. As shown in FIG. 6, the sorting device 36 includes a swing sorting unit 37 and a wind sorting unit 38.

The swing sorting unit 37 is disposed immediately below the ear piece processing device 29 (and the handling cylinder 16). The swing sorting unit 37 includes a feed pan 57, a chaff sheave 39, and a separator 73. In addition, the swing sorting unit 37 includes a swing drive mechanism (not shown) that swings the feed pan 57, the chaff sheave 39, and the separator 73 in the front-rear direction of the apparatus (left-right direction in FIG. 6).

The feed pan 57 is disposed on the upstream side of the chaff sheave 39 in the grain conveying direction, and is disposed at a position slightly higher than the chaff sheave 39. The feed pan 57 is a plate-like member, and is arranged slightly inclined with respect to the horizontal plane so that the downstream side in the grain conveying direction (the right side in FIG. 6, the rear of the apparatus) is lowered.

The object to be sorted from the spike cutting device 29 falls on the feed pan 57 or the chaff sheave 39. The object to be sorted that has fallen on the feed pan 57 is conveyed toward the downstream side (rear side of the apparatus) in the cereal conveying direction by the tilt of the feed pan 57 when the feed pan 57 is driven to swing, It falls onto the chaff sheave 39 from the downstream end of the feed pan 57.

The chaff sheave 39 is configured by arranging a plurality of chaff fins 40 horizontally arranged in the left-right direction of the apparatus side by side in the front-rear direction of the apparatus. The plurality of chaff fins 40 are arranged at an appropriate interval from each other.

By swinging the chaff sheave 39 back and forth, among the objects to be selected on the chaff sheave 39, heavy and small objects such as grains fall down between the chaff fins 40. On the other hand, light and large objects to be sorted such as sawdust remain on the chaff fin 40. In this way, it is possible to roughly sort the objects to be sorted by the chaff sheave. Each chaff fin 40 is disposed such that the upper surface thereof faces obliquely forward. Thereby, the sawdust etc. caught by the chaff fin 40 are conveyed toward the apparatus rear (right side of FIG. 6) by swinging the chaff sheave 39 in the apparatus front-rear direction.

The separator 73 will be described later.

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 wind sorting unit 38 is disposed below the swing sorting unit 37.

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 Kara fan 41 is configured to generate a downstream sorting wind in the grain conveying direction, and to apply the sorting wind to the Glen sheave 42 from below.

With the above-described configuration, the sorting wind generated by the Kara fan 41 is applied to the sorting object that has fallen on the Glen 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 item is introduced into the first conveyor 43, and the other ones with a light specific gravity are blown away toward the downstream side in the grain conveying direction.

The first thing (grain) introduced into the first conveyor 43 is transported 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.

The cuttings, swarf, etc. remaining on the chaff sheave 39 are transported toward the downstream side in the grain transporting 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 dropped on the second conveyor 44, the cuts of grains with grains are relatively heavy, so that 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 grains are blown away by the wind of the blower fan 45 and discharged out of the apparatus by the suction fan 51.

«Slices of grain with grain etc. 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 section 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 (second reduction mechanism) 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 port 47 of the second reduction conveyor 46 and is put into the ear cutting processing device 29. 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, there is a case where the object to be processed in the spear cutting apparatus jumps out to the handling cylinder side due to the rotational force of the processing cylinder. In particular, the threshing apparatus 1 of the present embodiment has a configuration in which the processing cylinder rotates in the same direction as the upper handling type handling cylinder 16, so that the object to be processed pops out from the end of the receiving net 31 toward the handling cylinder 16. There are circumstances that make it easy.

Therefore, the threshing apparatus 1 according to this embodiment is provided with a partition plate 34 between the handling cylinder 16 and the processing cylinder 30.

The partition plate 34 is made of a non-porous metal plate so that an object to be processed cannot pass through the partition plate. As shown in FIG. 3, when viewed from a direction orthogonal to the axis 32 of the processing cylinder 30, the partition plate 34 is disposed so as to block a straight line connecting the axis 17 of the handling cylinder 16 and the axis 32 of the processing cylinder 30. ing. As shown in FIG. 4, the partition plate 34 is provided at least over the entire length of the handling cylinder 16 in the direction of the axis 17. Further, as shown in FIG. 3, the lower end portion of the partition plate 34 is disposed close to the terminal 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, since the partition plate 34 is disposed so as to partially close the space between the handling cylinder 16 and the processing cylinder 30, the object to be processed in the earbrush processing apparatus 29 is subject to the rotational momentum of the processing cylinder 30. Can be prevented from jumping out toward the handling cylinder 16 side. 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 at 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, at least a part of the surface of the partition plate 34 facing the processing cylinder 30 is directed obliquely downward. As described above, the fact that at least a part of the partition plate 34 is arranged obliquely with respect to the vertical line causes the object to be processed in the cutting end processing device 29 to jump out to the barrel 16 side. The effect can prevent it well.

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 object to be processed is cut by the cutting teeth 49, 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. In the threshing apparatus 1 according to the present embodiment, since the partition plate 34 is arranged on the downstream side in the rotation direction of the processing drum 30 as viewed from the incisors 49, even if fine shavings are generated and scattered in the incisors 49 Can be prevented from being scattered on the side of the barrel 16.

Then, the 1st to-be-processed material guide plate (1st guide part) 35 with which the threshing apparatus of this embodiment is provided is demonstrated.

As described above, the object to be processed generated in the handling cylinder 16 is discharged toward the space 53 formed above the handling cylinder 16 by the rotational force of the handling cylinder 16. At this time, it suffices that all the objects to be processed generated in the handling cylinder 16 are put into the spike processing device 29, but if the objects to be processed discharged into the space 53 fly off an unexpected trajectory. In some cases, the object to be processed is not put into the ear-cut processing device 29, and the efficiency of the entire threshing device 1 is reduced.

In particular, in the threshing apparatus 1 of this embodiment, since the partition plate 34 is provided between the handling cylinder 16 and the processing cylinder 30, a part of the space between the handling cylinder 16 and the processing cylinder 30 is blocked. . As a result, the entrance to the ear-break processing device 29 is narrowed, and it is difficult for the workpiece to enter the ear-break processing device 29.

Therefore, the threshing apparatus 1 according to the present embodiment is provided with a first object guide plate 35 for guiding the object to be processed generated in the handling cylinder 16 to the process cylinder 30 of the earbrow processing apparatus 29.

The details will be described below. In the following description, “upstream side” and “downstream side” simply refer to the upstream side and the downstream side in the rotation direction of the handling cylinder 16.

The first workpiece guide plate 35 is a metal plate-like member, and is formed in a substantially rectangular shape as shown in FIG. As shown in FIG. 4, the first workpiece guide plate 35 is disposed such that its longitudinal direction is along the direction of the axis 17 of the handling cylinder 16 and faces the entire length of the handling cylinder 16 in the direction of the axis 17. It is configured to be able to.

As shown in FIG. 3, the first workpiece guide plate 35 is disposed further downstream than the downstream end 27 a of the ceiling plate 27. Therefore, it can be said that the first workpiece guide plate 35 is disposed on the downstream side of the starting point (the upstream end of the second ceiling plate 52) of the separation portion formed above the handling cylinder 16. be able to. Further, the first object guide plate 35 is disposed at a position where the object to be processed discharged from the handling cylinder 16 into the space 53 collides. Therefore, the object to be processed generated in the handling cylinder 16 is once discharged into the space 53 due to the rotational force of the handling cylinder 16 and then collides with the first object guide plate 35.

The first workpiece guide plate 35 is disposed on the upstream side of the processing cylinder 30 and above the processing cylinder 30. Further, the first workpiece guide plate 35 is disposed with the surface on the side of the handling cylinder 16 facing obliquely downward. Therefore, the object to be processed discharged from the handling cylinder 16 collides with the lower surface (surface facing obliquely downward) of the first object guide plate 35, and the lower end portion of the first object guide plate 35 is It is guided toward the direction (diagonally downward).

The first workpiece guide plate 35 is arranged such that the surface (lower surface) facing the handling cylinder 16 side passes above the upper end of the partition plate 34. Since the first workpiece guide plate 35 is arranged in this way, the workpiece guided by the lower surface of the first workpiece guide plate 35 can surely pass above the partition plate 34. As a result, the object to be processed discharged from the handling cylinder 16 into the space 53 can be guided into the spike processing apparatus 29 by the first object guide plate 35.

Further, the upper end of the first workpiece guide plate 35 and the ceiling surface of the handling chamber 15 are closed so that there is no gap. More specifically, a gap between the upper end of the first workpiece guide plate 35 and the ceiling surface of the handling chamber 15 is closed by a closing plate 55. As a result, the object to be processed does not slip over the first object guide plate 35, so that the object to be processed can be reliably guided by the first object guide plate 35.

Note that the upper end of the first workpiece guide plate 35 is fixed to the lower end of the closing plate 55 by screws (not shown). Thus, the 1st to-be-processed material guide plate 35 of this embodiment is comprised as a different body from the casing of the handling chamber 15, and is being fixed by the screwing. Therefore, the first workpiece guide plate 35 can be attached and detached by releasing the fastening of the screw. That is, the first workpiece guide plate 35 is a member that easily wears because workpieces such as grains frequently collide. Therefore, by making it detachable as described above, the worn first workpiece guide plate 35 can be replaced. In the present embodiment, the lower end of the first workpiece guide plate 35 is not particularly fixed and is free.

Further, a plurality of adjustment plates 56 are attached to the lower surface (the surface facing the handling cylinder 16 side) of the first workpiece guide plate 35. As shown in FIG. 7, the adjustment plate 56 is made of a metal plate member bent at a substantially right angle, and is substantially orthogonal from the surface of the first object guide plate 35 facing the treatment cylinder 16 side. It is provided so as to protrude in the direction.

The plurality of adjusting plates 56 are arranged side by side in a direction (left-right direction in FIG. 4) parallel to the axis 32 of the processing cylinder 30 as shown in the cross-sectional plan view of FIG. Further, each adjustment plate 56 is disposed so as to be inclined with respect to a direction parallel to the axis 32 of the processing cylinder 30.

With the above configuration, the workpiece that has jumped out of the handling cylinder 16 is guided by the adjustment plate 56 in an oblique direction with respect to the axial direction of the processing cylinder 30 when it collides with the first workpiece guide plate 35. Introduced into the spike breaker 29. In this way, by guiding the object to be processed by the adjusting plate 56 disposed obliquely, the object to be processed can be dispersed 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.

As described above, the threshing apparatus 1 of the present embodiment includes the handling cylinder 16, the processing cylinder 30, the first workpiece guide plate 35, and the partition plate 34. The handling cylinder 16 rotates upwardly about an axis 17 set substantially horizontally, and has a plurality of teeth 22 on the outer periphery. The processing cylinder 30 rotates about an axis 32 set substantially parallel to the axis 17 of the handling cylinder 16 and at a position lower than the axis 17, and has a plurality of processing teeth 33 on the outer periphery. The first workpiece guide plate 35 guides the workpiece generated in the handling cylinder 16 toward the processing cylinder 30 by the lower surface. The partition plate 34 is disposed between the handling cylinder 16 and the processing cylinder 30. 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 first workpiece guide plate 35 is disposed such that the lower surface 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 towards In addition, since the workpiece is guided by the first workpiece guide plate 35, the workpiece can be smoothly fed into the processing cylinder 30. With the above configuration, the object to be processed generated in the handling cylinder 16 can be reliably processed by the processing cylinder 30, so that the efficiency of the entire threshing apparatus can be improved.

Then, the 2nd to-be-processed material guide plate (2nd guide part) 63 with which the threshing apparatus 1 of this embodiment is provided is demonstrated.

As already described, the threshing apparatus 1 according to the present embodiment guides the processing object discharged from the handling cylinder 16 by the lower surface of the first processing object guide plate 35, and thereby guides it to the spike processing apparatus 29. It is the structure to do. However, in reality, not all of the objects to be processed generated in the handling cylinder 16 fly along an ideal trajectory that is guided by the first object guide plate 35 and enters the spike processing device 29. For example, as shown by reference numeral 61 in FIG. 3, when the object to be processed collides with a member other than the first object guide plate 35, the object to be processed rebounds in an unexpected direction. If the object to be processed does not fly along an ideal trajectory, the object to be processed cannot enter the spike processing device 29 and falls between the processing cylinder 30 and the handling cylinder 16. there is a possibility.

Therefore, the threshing apparatus 1 of the present embodiment is provided with a second object guide plate 63 that receives the object to be processed generated in the handling cylinder 16 on the upper surface and guides the object to the spike processing apparatus 29.

The second workpiece guide plate 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 axis 32 of the processing cylinder 30, it passes through the vertical line passing through the center of the axis 17 of the handling cylinder 16 and the center of the axis 32 of the processing cylinder 30. A second workpiece guide plate 63 is disposed between the vertical line and the vertical line. The second workpiece guide plate 63 is disposed upstream of the processing cylinder 30 in the rotation direction of the handling cylinder 16. Further, the second object guide plate 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 second workpiece guide plate 63 is disposed between the handling cylinder 16 and the processing cylinder 30, the object to be processed passing between the handling cylinder 16 and the processing cylinder 30 is dropped. An object can be received by the upper surface of the second workpiece guide plate 63.

In the present embodiment, the second workpiece guide plate 63 is a single metal plate, and the upper surface thereof is formed to be substantially smooth to form a guide surface 63a. As shown in FIG. 3, when viewed in the direction of the axis 32 of the processing cylinder 30, the guide surface 63 a of the second workpiece guide plate 63 is disposed obliquely with respect to the horizontal plane. More specifically, the end of the guide surface 63a on the processing cylinder 30 side is arranged to be 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.

Further, as shown in FIG. 3, the end of the guide surface 63 a on the processing cylinder 30 side is disposed 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 processing device 29.

As described above, the threshing apparatus 1 of the present embodiment handles the second workpiece guide plate 63 that receives the workpiece generated in the handling cylinder 16 on the upper surface and guides the workpiece to the processing cylinder 30. It is provided between the cylinder 16 and the processing cylinder 30.

By providing the second workpiece guide plate 63 in this way, an untreated workpiece is prevented from falling between the handling cylinder 16 and the processing cylinder 30, and the processing cylinder is received by receiving the workpiece. You can guide up to 30.

Subsequently, the spiral guide member 65 provided in the spike breakage processing device 29 of the present embodiment will be described. The spiral guide member 65 is for transporting the object to be processed in the cutting edge processing device 29 along the direction of the axis 32 of the processing cylinder 30.

As shown in FIG. 3, the spiral guide member 65 is disposed between the processing cylinder 30 and the partition plate 34. As shown in FIG. 8, the spiral guide member 65 is a flat plate-like member. Further, the cut end treatment device 29 of this embodiment includes a plurality of the spiral guide members 65. The plurality of spiral guide members 65 are arranged in parallel to each other, and are arranged side by side at an appropriate interval in a direction parallel to the axis 32 of the processing cylinder 30.

As shown in FIG. 3, when viewed in the direction of the axis 32 of the processing cylinder 30, the spiral guide member 65 has an annular shape on the end surface on the processing cylinder 30 side along the rotation locus of the tip of the processing tooth 33. It is formed in an arc shape. The spiral guide member 65 is disposed outside the rotation locus of the distal end of the processing tooth 33. As a result, the spiral guide member 65 does not interfere with the rotating processing teeth 33.

4 and FIG. 9, the plate-like spiral guide member 65 is disposed so as to be inclined with respect to a direction parallel to the axis 32 of the processing cylinder 30 (the apparatus longitudinal direction).

Since the spiral guide member 65 is disposed as described above, the end surface of each spiral guide member 65 facing the processing cylinder 30 is disposed so as to substantially follow the spiral centering on the axis 32 of the processing cylinder 30. I can say that. In the present embodiment, the spiral guide member 65 is disposed along a spiral in the left-handed screw direction around the axis 32 of the processing cylinder 30.

The operation of the spiral guide member 65 arranged as described above will be described.

The object to be processed in the earbrush processing device 29 is rotated around the axis 32 in the earbrowth processing device 29 by the rotating processing cylinder 30 and the processing teeth 33. Thus, the workpiece to be rotated around the axis 32 is guided by the spiral guide member 65 and moves along the spiral guide member 65 when passing between the processing cylinder 30 and the partition plate 34. Since the spiral guide member 65 is disposed along a spiral centering on the axis 32 of the processing cylinder 30, the object to be processed guided by the spiral guide member 65 moves along the spiral.

As described above, the spiral guide member 65 is arranged along the spiral of the left screw. Further, in the ear burn processing device 29 of the present embodiment, as shown in FIG. 3, the processing cylinder 30 is configured to rotate counterclockwise (counterclockwise) when viewed from the front side (front side) of the device. . Accordingly, the object to be processed guided by the spiral guide member 65 is conveyed toward the rear of the apparatus (on the downstream side in the grain conveying direction) in the spike processing apparatus 29.

In this manner, the object to be processed in the earbrush processing apparatus 29 can be conveyed along the axis 32 of the processing cylinder 30, so that the object to be processed in the ear cutting apparatus 29 is transferred to the axis 32 of the processing cylinder 30. Can be dispersed in the direction. For example, the amount of workpieces to be fed from the handling cylinder 16 into the earbrush processing device 29 is larger on the front side of the device (upstream side in the grain transporting direction) and on the rear side (downstream image in the grain transporting direction) The amount of processed material is small. Therefore, as described above, the object to be processed in the spike breakage processing apparatus 29 is conveyed toward the rear of the apparatus by the spiral guide member 65, whereby the object to be processed is dispersed in the axial direction of the processing cylinder 30. it can. As a result, the end-of-ear processing apparatus 29 can be effectively used uniformly over the entire length of the processing cylinder 30, so that the processing efficiency of the end-of-ear processing apparatus 29 can be improved.

Since the object to be processed in the spike processing device 29 is subjected to the action of the rotating processing teeth 33 many times while being conveyed toward the rear of the device, the grains contained in the object to be processed are made into single grains. At the same time, sawdust is shredded. Grains and fine sawdust fall through the receiving net 31 to the sorting device 36. On the other hand, the large dust that has not been shredded finally reaches the rear end portion (the end portion on the downstream side in the grain transporting direction) of the ear-break processing device 29.

As shown in FIGS. 4, 8, and 9, a throwing blade 68 that rotates integrally with the processing cylinder 30 is provided at the rear end of the processing cylinder 30. The throwing blades 68 are plate-like members arranged in parallel with the axis 32 of the processing cylinder 30, and a plurality of the throwing blades 68 are provided so as to protrude from the periphery of the processing cylinder 30. Further, the receiving net 31 is not provided in the throwing blade 68 portion. That is, the lower side of the throwing blade 68 is open.

As shown in FIG. 6, a separator 73 of the swing sorting portion 37 is provided below the throwing blade 68. As shown in FIG. 4, the separator 73 has a configuration in which a large number of linear members (wires) 69 are arranged in parallel at appropriate intervals in the left-right direction of the apparatus. As shown in FIG. 6, the separator 73 is disposed above the chaff sheave 39.

With the above-described configuration, the object to be processed (large dust or the like) conveyed to the rear end portion in the spike breaker 29 is thrown downward by the rotation of the throwing blade 68 and falls onto the separator 73. At this time, large dust or the like is caught on the linear member 69 and remains on the separator 73. When the grain is mixed in the processing object that has fallen on the separator 73, the grain passes between the linear members 69 and falls onto the chaff sheave 39. The object to be processed (large dust or the like) finally remaining on the separator 73 is sucked by the suction fan 51 and discharged outside the apparatus.

It should be noted that the object to be processed falling from the rear end portion of the spike breakage processing device 29 is spread in the left-right direction of the device due to the rotational momentum of the throwing blades 68. Therefore, a large catalyzed workpiece does not fall on the separator 73. Thereby, the loss which cannot be isolate | separated with the grain mixed in the catamaric dust and is discharged outside the machine can be prevented.

As explained above, in the threshing apparatus 1 of the present embodiment, the ear-breaking processing device 29 is disposed so as to face the peripheral surface of the processing cylinder 30 and is substantially spirally centered on the axis of the processing cylinder 30. A spiral guide member 65 arranged along the line is provided.

By providing the spiral guide member 65 in this way, the object to be processed in the spike processing device 29 can be conveyed along the axial direction of the processing cylinder 30. Thereby, it is possible to prevent large dust from staying in the ear break processing device 29 and to improve the processing efficiency of the ear cut processing device 29.

Next, in the threshing apparatus of the present embodiment, a configuration in which the second thing is processed by the spike cutting apparatus 29 will be described. The threshing apparatus 1 according to the present embodiment inputs the second thing discharged from the discharge port 47 of the second reduction conveyor 46 into the spike processing apparatus 29 while guiding it in a direction parallel to the axis 32 of the processing cylinder 30. A number guide passage 48 is provided.

The details will be described below. As shown in FIGS. 3, 4, and 10, the second guide passage 48 is configured as a space surrounded by a bottom surface 70, a side wall 71, and a ceiling 72 (in FIG. 4, The ceiling 72 is omitted to show the inside of the second guide passage 48). As shown in FIGS. 4 and 10, the discharge port 47 of the second reduction conveyor 46 is connected to one end of the second guide passage 48 in the longitudinal direction. With this configuration, the second item conveyed by the second reduction conveyor 46 is discharged into the second guide passage 48.

As shown in FIG. 10, the longitudinal direction of the second guide passage 48 is disposed so as to be oblique to the horizontal plane. The discharge port 47 is connected to the higher end portion of the second guide passage 48 disposed obliquely. Accordingly, the second object discharged from the discharge port 47 is naturally guided to the lower side along the longitudinal direction of the second guide passage 48 by the action of gravity. As shown in FIG. 4, the longitudinal direction of the second guide passage 48 is arranged so as to substantially follow the axis 32 of the processing cylinder 30 in plan view. Accordingly, the second object discharged from the discharge port 47 is guided along the axis 32 of the processing cylinder 30 by the second guide passage 48.

As shown in FIG. 3, in the cross section orthogonal to the axis 32 of the processing cylinder 30, the bottom surface 70 of the second guide passage 48 is closed at one end by a side wall 71 and the other end is open. Has been. In the following description, the end on the open side of the bottom surface 70 is called an open end, and the end on the side closed by the side wall 71 is called a closed end. As shown in FIG. 3, in the cross section orthogonal to the axis 32 of the processing cylinder 30, the bottom surface 70 is disposed obliquely with respect to the horizontal plane so that the open end is lower than the closed end. With the above configuration, the second object guided in the second guide passage 48 can fall downward from the open end of the bottom surface 70.

As shown in FIG. 3, the second guide passage 48 is disposed at a position higher than the spike breakage treatment device 29. In the cross section perpendicular to the axis 32 of the processing cylinder 30 (FIG. 3), the open end of the bottom surface 70 of the second guide passage 48 is the starting end of the receiving net 31 of the ear-cut processing device 29 (in the rotational direction of the processing cylinder 30). It is located above the upstream end). The bottom surface 70 is arranged so that the open end faces the processing cylinder 30. With the above configuration, the second item falling from the open end of the bottom surface 70 is thrown into the spike breaker 29.

As shown in FIG. 4, in the plan view, the second guide passage 48 is configured such that the width of the bottom surface 70 becomes narrower as the distance from the discharge port 47 increases. As described above, the bottom surface 70 is disposed obliquely so that the open end is lower than the closed end. Therefore, the second object guided in the second guide passage 48 will soon fall from the open end of the bottom surface 70 sooner or later. With the above configuration, the second object discharged from the discharge port 47 falls from the open end of the bottom surface 70 while being guided in the second guide passage 48 in the direction along the axis 32 of the processing cylinder 30. It is put into the spike breaker 29.

Since the second thing discharged from the discharge port 47 has various speeds and directions, a certain second object falls at a position close to the discharge opening 47, and a certain second thing falls at a position far from the discharge opening 47. Will do. Accordingly, the positions at which the second item is thrown into the spike processing device 29 are appropriately dispersed in the direction of the axis 32 of the processing cylinder 30.

In this way, the second guide passage 48 is provided so as to be substantially along the axis 32 of the processing cylinder 30, so that the second product discharged from the discharge port 47 of the second reduction conveyor 46 is transferred to the axis 32 of the processing cylinder 30. After being dispersed in the direction, it can be supplied to the spike breaker 29. Thereby, it can prevent that the second thing collects and is supplied to the specific position of the ear | edge piece processing apparatus 29, and can use the said ear piece processing apparatus 29 effectively over the full length.

In the present embodiment, as shown in FIG. 4, the discharge port 47 of the second reduction conveyor 46 is configured to discharge the second product from the downstream side toward the upstream side in the conveying direction of the cereal basket 14. ing. Further, the bottom surface 70 of the second guide passage 48 becomes narrower as it goes from the downstream side to the upstream side in the conveying direction of the grain pod 14. And this bottom face 70 is not formed to the upstream edge part of the processing cylinder 30 in the conveyance direction of the grain basket 14 (namely, the bottom face 70 is interrupted on the way). With the above-described configuration, the second guide passage 48 does not supply much second product to the upstream side of the cut end treatment device 29.

Moreover, in the threshing apparatus 1 of this embodiment, as shown in FIG. 3, when viewed from the direction of the axis 32 of the processing cylinder 30, the discharge port 47 of the second reduction conveyor 46 is connected to the first workpiece guide plate 35. Is located on the opposite side of the handling cylinder 16. That is, the first workpiece guide plate 35 is disposed between the discharge port 47 and the handling cylinder 16. For this reason, even if the second object discharged from the discharge port 47 scatters toward the handling cylinder 16, the second object collides with the first object guide plate 35, so that the second object is handled. It is possible to prevent jumping out toward the barrel 16 side.

In the present embodiment, a plurality of second object adjusting plates 74 are attached to the upper surface of the first object guide plate 35 (the surface facing the discharge port 47). The second object adjusting plate 74 is provided so as to protrude from the upper surface of the first object guide plate 35 in a substantially orthogonal direction. The plurality of second article adjusting plates 74 are arranged side by side in a direction parallel to the axis 32 of the processing cylinder 30. Further, each second object adjusting plate 74 is disposed so as to be inclined with respect to a direction parallel to the axis 32 of the processing cylinder 30.

The second thing adjusting plate 74 can be aimed at the same effect as the adjusting plate 56 described above. That is, the second object that has collided with the first object guide plate 35 is introduced into the spike processing device 29 while being guided by the second object adjusting plate 74 in an oblique direction with respect to the axial direction of the processing cylinder 30. Is done. In this way, by guiding the second object with the second object adjusting plate 74, the position where the second object is thrown into the panicle processing device 29 is dispersed in a direction parallel to the axis 32 of the processing cylinder 30. be able to. As a result, it is possible to more effectively use the ear-break processing device 29 in the direction of the axis 32 of the processing cylinder 30.

As described above, the threshing apparatus 1 of the present embodiment includes the sorting device 36, the second reduction conveyor 46, and the second guide passage 48. The sorting device 36 sorts the objects to be processed, which have been processed by the cutting edge processing device 29, into at least a first item that does not require reprocessing and a second item that requires reprocessing. The second reduction conveyor 46 conveys the second item sorted by the sorting device 36 to the upper part of the ear cutting processing device 29.
