A dust removal treatment chamber 4 is provided in which a dust removal treatment cylinder 35 having a dust removal treatment net 34 to be processed is mounted on a dust removal treatment cylinder shaft 36. A swing sorting shelf 2 is provided below the handling chamber 1 and the dust disposal chamber 4.

  Further, a second processing chamber 41 including a second processing drum 39 and a second processing drum receiving rod 40 (which may be a net or a lattice) is configured in front of the dust removal processing drum 35. In this embodiment, the second processing cylinder 39 is on one side of the grain tank 16 on the handling cylinder 31 and is integrally formed with the dust processing cylinder 35 in front of the dust processing cylinder 35. The second processing cylinder 39 basically processes a second product. Since the second processing cylinder 39 is supported by the second processing cylinder shaft 42, the dust processing cylinder 35 and the second processing cylinder 39 are integrated with the dust processing cylinder shaft 36 and the second processing cylinder 39. The structure is supported by the processing cylinder shaft 42.

  Further, FIG. 5 is a cross-sectional view taken along the line AA shown in FIG. 4. Since the workpiece leaked from the handling net 30 is taken into the second processing chamber 41, the second processing cylinder 39 is In addition to the second item, the object to be processed that has entered from the handling chamber 1 is also processed together. The handling net 30, the second treatment cylinder receiving rod 40 (which may be a net or a lattice), and the dust treatment net 34 are provided below the treatment cylinder 31, the second treatment cylinder 39, and the dust treatment cylinder 35, respectively. Yes.

  The dust removal processing teeth 35a of the dust removal processing cylinder 35 need to be fixed in such a direction as to send the cereal from the rear part of the handling chamber 1 in the lower direction of the sorting wind feed direction. In the present embodiment, the dust removal treatment teeth 35 a have a spiral shape that is wound around the outer peripheral surface of the dust removal treatment cylinder 35.

  A dust feed lead plate 70 is provided in the first half of the dust removal treatment cylinder 35 to quickly feed the workpiece to the rear, and a cutting blade 71 is attached to the middle portion to cut the workpiece to be cut short. Yes. Reference numeral 54 denotes a discharge port of the dust removal processing cylinder 35.

  Below the handling chamber 1, the second processing chamber 41, and the dust processing chamber 4, a swing sorting shelf 2 that receives and sorts the falling objects to be sorted is installed. Is provided with a tang 43 on the start side of the sorting air feed direction, and an air passage 44 and an air passage 45 are provided on the lower side of the sorting air sent from the tang 43 in the feeding direction. The first spiral 46 is provided on the lower side of 44 and the air passage 45, and the second spiral 47 is provided on the lower side of the first spiral 46 in the sorting wind feed direction. A second lifting cylinder 48 is provided for lifting the second thing collected in the second helix 47 to the second processing chamber 41.

  The configuration of the swing sorting shelf 2 will be described. The swing sorting shelf 2 includes a transfer shelf 49 for transferring the fallen cereals backward, a grain sheave 38a for sorting the cereals, a chaff sheave 38b for sorting the second thing, and a sorting wind. The fixed chuck 38c for guiding, and the Strollac 3 for loosening the dust-treated product and collecting the scorpion particles and transferring the dust-treated product to the outside and releasing it. Below the Strollac 3 is constituted by a second shelf tip 47a for guiding the second item into the second spiral 47, and the dust removal processing cylinder 35 extends to the vicinity of the terminal end of the second shelf tip 47a. It is the composition which has taken out. The suction fan 6 is for discharging light dust in the sorting chamber 50 to the outside of the machine, and is provided at a position facing the dust removal processing cylinder 35 with respect to the handling cylinder 31. Reference numeral 52 denotes a crankshaft that drives the swing sorting shelf 2 to swing.

  The culm that has been conveyed from the reaping device 83 is taken over by the start end of the feed chain 15 of the threshing device 89, and the cereal that has been taken over by the feed chain 15 is conveyed rearward while It is threshed by the handling net 30. A portion of the threshed threshing falls on the swing sorting shelf 2 and is sorted by the swinging action of the swing sorting shelf 2 and the wind sorting action from the Kara 43 and taken into the first spiral 46. Accordingly, the grain taken into the first spiral 46 is configured to be temporarily stored in the glen tank 16. After the threshing, the waste is handed over from the terminal end of the feed chain 15 to the start end of the waste chain 18 and then sent to the cutter 19 where it is cut and released onto the lower field. It has become.

  The remaining threshing in the handling chamber 31 is transferred to the dust removal processing chamber 4, and part of the threshing is taken into the second processing chamber 41 along the way. The threshing taken into the second processing chamber 41 is threshed by the interaction between the second processing cylinder 39 and the second processing cylinder receiver 40 while being transported to the upper side in the sorting wind feed direction (particularly branch infarction grains). Is dropped on the swing sorting shelf 2 below. The handling cylinder 31, the second processing cylinder 39, and the dust removal processing cylinder 35 are configured to rotate clockwise in a front view of the threshing device 89 that looks from the upper side to the lower side in the sorting wind feed direction. Therefore, it is necessary to fix the direction of the processing teeth 39a of the second processing cylinder 39 in such a direction as to send the cereals in the upper direction of the sorting wind feed direction.

  That is, the processing teeth 39a have an action of conveying the workpiece to the upper side in the sorting air feed direction, and further have an action of processing the workpiece. That is, the processing tooth 39a is a part of a spiral, and is configured to process the object to be processed by the interaction between the circumferential tip portion thereof and the second processing cylinder receiving rod 40. The blades 39b provided at the conveying terminal end of the second processing cylinder 39 forcibly send the workpiece to the swing sorting shelf 2.

  In the dust disposal chamber 4, since the mesh of the dust disposal network 34 is rough, some short sawdust falls on the swing sorting shelf 2, and long sawdust that has not fallen falls into the dust disposal chamber. 4 is conveyed to the end portion of the dust discharge cylinder 35 and is forcibly discharged onto the Strolac 3 from the discharge port 54 by the blade 35b at the end portion of the dust removal processing cylinder 35. While the workpiece is thus transported in the dust treatment chamber 4, the dust treatment cylinder 35, the dust treatment teeth 35a provided with the dust treatment cylinder 35, and the dust treatment network. Through the interaction with No. 34, the threshing is further thawed, the threshing is broken and the grains so-called scorpion grains mixed in are taken out and fall onto the lower swing sorting shelf 2, and It is configured to be collected into the spiral 47.

  As described above, the remaining threshing that has not fallen on the swing sorting shelf 2 due to cerealing in the handling chamber 1 and has not been taken into the second processing chamber 41 is transported to the end of the handling chamber 1. It will be done. The threshing that has been transported to the terminal end of the handling chamber 1 is taken into the dust removal processing chamber 4 and the taken threshing is transported to the lower side in the sorting wind feed direction. Further, of the cereals that have been transported to the end of the handling chamber 1, the cereals that have not been taken into the dust disposal chamber 4 fall on the swinging sorting shelf 2 below.

  In order to prevent clogging of the cereal when the cereal is sent from the terminal end in the handling chamber 1 to the dust disposal chamber 4, the dust disposal cylinder is also provided at the takeover portion from the handling chamber 1 to the dust disposal chamber 4. Spiral-shaped dust removal processing teeth 35a are provided on the outer periphery of 35, and the take-off portion is prevented from being clogged by the feeding action of the dust removal processing teeth 35a.

  In spite of the swinging action of the swinging sorting shelf 2 and the action of the sorting wind from the red pepper 43, the remaining grains that are not taken into the spiral 46 together with other dust are further removed. It is sent to the rear and taken into the second spiral 47. The second product taken into the second spiral 47 is reduced to the lower side in the sorting air feed direction of the second processing chamber 41 by the second lifting cylinder 48 and merged with the cereal from the handling chamber 1. Then, while being transported to the upper side of the sorting wind feed direction, it is transported while being threshed by the interaction with the second processing cylinder receiving rod 40, and is placed on the lower swing sorting shelf 2 by the blade 39b at the end portion. It is the composition that falls forcibly.

  Reference numeral 5 shown in FIG. 3, FIG. 6, FIG. The dust removal rack 5 has a plate-like body 5a arranged horizontally and fixed at a constant pitch P1 above the Strollack 3 and on the lower surface side of the mounting plate 7 which is horizontally mounted on the frame of the swing sorting shelf 2. Yes. About the shape of the attachment plate 7 to which the plate-like body 5a of the dust removal rack 5 is attached, the front side 59a is bent forward and downward, and the rear side 59b is bent upward and backward. As a result, the sorting wind G has a flow as indicated by an arrow, so that the sorting wind can be prevented from going directly toward the discharge port 57, and single grains can be prevented from being discharged directly outside the apparatus. become.

  Further, as shown in FIG. 7, the horizontal arrangement interval P1 of the plate-like bodies 5a of the dust removal rack 5 is wider than the horizontal arrangement interval P2 of the plate-like bodies 3a of the lower Strollac 3, and the suction fan 6 is used. On the side, the weight is reduced by using the omitted interval P3 in which the dust removal racks 5 are omitted by a few pitches.

  Then, the processing object discharged from the discharge port 54 at the terminal end of the dust removal processing chamber 4 is received by the dust removal rack 5 and is rocked and unwound so that the scorpion grains can be dropped and collected. The installation position of the mounting plate 7 is substantially the same as the installation end position of the dust feed lead plate 70 in the dust disposal chamber 4 so that the processing object falling from the second half of the dust disposal chamber 4 is received by the dust rack 5. In this way, it will be solved by receiving finer cut pieces and processed objects that have remained long.

  Further, the object to be processed discharged from the discharge port 54 at the end of the dust removal processing chamber 4 is received by the dust removal rack 5 and is not directly placed on the strola rack 3. Do not merge with the workpiece to be sent. Therefore, the processing capacity of the swing sorting shelf 2 does not decrease. In addition, a large and light object to be processed discharged from the discharge port 54 at the end of the dust disposal chamber 4 is sucked into the suction fan 6 while rolling on the dust rack 5, so that Ejection to the outside of the machine will be performed quickly and efficiently. In particular, since the plate-like body 5 a of the dust removal rack 5 is fixed to the lower surface side of the mounting plate 7, the dust collected on the mounting plate 7 is sucked out by the suction fan 6 without being caught.

  Reference numeral 55 denotes an axial center of the suction fan 6, and B denotes the rotation direction of the suction fan 6. And since the dust removal rack 5 is located behind the axial center 55 of the suction fan 6, the dust on the dust removal rack 5 rolls upward from the relationship with the rotation direction of the suction fan 6. However, it is sucked into the suction fan 6. As a result, the scorpion grains fall and collect in the middle of the upward winding, so that the loss is reduced. Further, since the dust removal rack 5 is located in the vicinity of the lower end portion of the suction port 56 of the suction fan 6, it can be prevented from becoming a discharge resistance.

  A plate-like body 3a constituting the Strollac 3 is mounted at a predetermined pitch P2 on the lower surface of a Strollac connecting plate 73 that is horizontally mounted on the rear side of a fixed chaff sheave 38c, which will be described later. The lower surface of the mounting plate 7 of the dust removal rack 5 is narrowed toward the rear upper side, so that the suction air from the suction fan 6 and the sorting air from the tang 43 are accelerated on the dust removing rack 5 side, and the suction sorting effect. Is increasing.

Although 57 is a discharge port of the terminal part of a threshing device, since it has the discharge port 57 to the outside of the machine in addition to the suction fan 6, highly efficient work is possible.
The length D of the dust removal rack 5 is longer than the length C of the Strollack 3 and extends below the dust removal treatment cylinder 35 so that the processed material with less grains falling from the dust removal treatment cylinder 35 is directly placed on the chaff sheave 38b. It is configured not to fall. And the position of the front-end | tip part of the dust removal rack 5 is set behind the front-end | tip part of the stroll rack 3. FIG. As a result, it is possible to prevent the flow of the sorting air that passes through the top of the shelf 58 and blows up the chaff sheave 38b and the fixed chaff sheave 38c from being obstructed.

Moreover, since the position of the terminal part of the dust removal rack 5 is set behind the swing sorting shelf 2, the dust discharged from the dust treatment chamber 4 can be efficiently guided outside the apparatus. .
The vertical length E of the plate-like body 5 a constituting the dust removal rack 5 is configured to be shorter than the vertical length F of the plate-like body 3 a constituting the Strollac 3. As a result, the space between the dust removal rack 5 and the stroller rack 3 is widened, so that it is possible to prevent troubles in feeding a coarse long wall or the like.

  As described above, the swing sorting shelf 2 is configured with a plurality of grain sheaves 38a, and the start end of the grain sheave 38a is configured to be positioned in front of the conventional one. Specifically, it is configured to be positioned in front of the dropping port 60 at the terminal end of the handling chamber 1 and forward by the length of the width of the dropping port 60. As a result, since the object to be processed falling from the handling chamber 1 can be sorted in advance, the sorting performance is improved.

  Each of the grain sheaves 38a is connected by a connecting plate 61, and a tension spring 62 is provided between the connecting plate 61 and the swing sorting shelf 2 main body. Therefore, the grain sieve 38a is always in the opening direction. In addition, a plurality of chaff sheaves 38b are formed behind the Glen sheave 38a, and the plurality of chaff sheaves 38b are also connected by a connecting plate 63. A stopper plate 64 is attached to the front portion of the connecting plate 63. The stopper plate 64 is in contact with the connecting plate 61 of the grain sieve 38a. Therefore, the opening degree of the grain sheave 38a is regulated by the opening degree of the chaff sheave 38b. That is, when the chaff sheave 38b opens and closes, the grain sheave 38a also opens and closes. This eliminates the need for a complicated link mechanism or the like for opening and closing the grain sieve 38a, and reduces the weight. Further, by providing the stopper plate 64, the swing sorting shelf 2 is reinforced.

Since the tension spring 62 is positioned in front of the plurality of chaff sheaves 38b and above the cable 67, interference between the members can be prevented.
Further, in such a configuration, the rotation angle of the grain sheave 38a and the opening angle of the chaff sheave 38b are substantially the same. And even if the opening angle of the grain sheave 38a is fully open, the chaff sheave 38b is configured to rotate in the opening direction. As a result, the object to be processed that could not be sorted by the grain sieve 38a can be sorted by the chaff sheave 38b, so that the loss is reduced.

  Further, since the state where the opening angle of the grain sieve 38a is fully opened is set to be the standard position of rice, it is possible to promote filtration in front of the swing sorting shelf 2. And since the to-be-processed object guide | induced to the chaff sheave 38b from the terminal end of the handling chamber 1 is restrict | limited, it will become possible to prevent mixing of a green leaf and a hull.

  Further, in the state where the Glen sheave 38a and the chaff sheave 38b are fully closed, they are configured to be fully closed at substantially the same angle. Thereby, contamination can be effectively mixed.

  As shown in FIG. 11, since the stopper plate 64 is configured to be easily removed when the hair pin 65 is removed, inspection and maintenance can be easily performed. Further, when the stopper plate 64 is removed, the grain sheave 38a is fully opened regardless of the movement of the chaff sheave 38b. For example, even if the cultivar has little generation of wheat and straw scraps, the amount of filtration in the front grain sieve 38a is reduced. The rear chaff sheave 38b can prevent contamination from entering.

  Further, since the stopper plate 64 is attached to the side surface of the swing sorting shelf 2, the stopper plate 64 can be removed and attached by providing a detachable window not shown on the side wall of the threshing device corresponding to this portion. It becomes easy. That is, since the swing sorting shelf 2 itself does not have to be removed from the threshing device, inspection and maintenance are facilitated.

  Reference numeral 66 denotes a tension spring that pulls each chaff sheave 38b in the opening direction. Therefore, the opening angle can be stabilized regardless of the weight of the workpiece. Also, even if the cable 67 is cut, the direction is always open, so that the third loss can be prevented from increasing.

  The upper surface line I of the chaff sheave 38b is configured to rise rearward with respect to the upper surface line H of the grain sheave 38a. Thereby, the flow on the grain sieve 38a is improved. In addition, since the passage time is longer on the chaff sheave 38b, the sorting is improved.

  Further, the length 68 between the Glen sheaves 38a is configured to be shorter than the length 69 between the chaff sheaves 38b. As a result, it becomes difficult for the flaws to fall off from each of the grain sieves 38a, so that the first sorting performance can be prevented from being lowered.

Furthermore, since the length between the grain sieves 38a is short, the object to be processed on the grain sieves 38a is smoothly fed.
A fixed chaff sheave 38c having a fixed opening is provided at the rear of the chaff sheave 38b so that the sorting air from the tang 43 is sent to the dust rack 5 with a predetermined strength. The fixed chaff sheave 38c is located directly below the mounting plate 7 of the dust removal rack 5, and prevents the object to be processed from falling directly, thereby preventing clogging.

  The embodiment shown in FIG. 12 has a configuration in which a rear chaff sheave 38d is provided in place of the Strollac 3, and the rear chaff sheave 38d has the same configuration as the front chaff sheave 38b and is provided with a connecting plate 63 that bypasses the fixed chaff sheave 38c. The opening can be changed at the same time. By providing the rear chaff sheave 38d in place of the Strollac 3a, it is possible to reduce the dust mixed into the second spiral 47.

  The length L2 of the fixed chaff sheave 38c is longer than the length L1 of the front chaff sheave 38b and the length L2 of the rear chaff sheave 38c to guide the flow of the sorting wind. The length L1 of the front chaff sheave 38b and the length L2 of the rear chaff sheave 38d are the same, and selection of the scorpion grains is performed.

  The intervals between the sheaves from the pre-sheave 38a to the rear chiff sheave 38d are such that the pre-sheave 38a <the front chiff sheave 38b <the fixed chaff sheave 38c, and the opening of the rear chiff sheave 38d is the same as the opening of the front chiff sheave 38b. Corresponding to the size of the falling sawdust, the sorting wind from the Karatsu 43 acts strongly, so that the sawdust and the shredder falling on the second spiral 47 are reduced.

  Note that the total length from the pre-sheave 38a to the rear chaff sheave 38d is substantially the same as the length of the dust-removing treatment cylinder 35 located at the upper part, so that the dust falling from the dust-removal treatment cylinder 35 is treated.
