Description

  The present invention relates to a threshing processing apparatus mounted on a combine or the like.

Conventionally, in a threshing processing apparatus in which a processing chamber and a processing chamber are arranged side by side, a part of the processed material is sent into the processing chamber from the starting end side of the processing chamber and processed while being fed backward by the processing cylinder in the processing chamber, A part of the treated product is again reduced to the treatment chamber end side (see, for example, Patent Document 1), or the treatment chamber start end side and the treatment chamber start end side are communicated to each other. There is a configuration (for example, refer to Patent Document 2) in which the side and the middle part of the processing chamber communicate with each other and the processed material in the processing chamber is sent into the processing chamber from both the front and rear sides.
JP 2005-295846 A Japanese Patent Laid-Open No. 10-174514

  In all of these conventional examples, in order to reduce the threshing load in the handling chamber, a part of the processed material generated at the starting end side of the handling chamber is sent into the processing chamber for processing. Since it is processed while being sent backward, the processed material that leaks from the receiving network falls in a large amount from the middle part to the end side of the swing sorting shelf, placing a burden on sorting and exerting a sufficient sorting effect However, there was a problem that the grain was discharged out of the machine, resulting in a loss of harvest.

  The present invention is to solve such a problem, and while reducing the threshing load in the processing chamber, in the processing chamber, the processed product from the start end side of the processing chamber and the second reduction processed product from the processing chamber. In addition, the leaked processed product falls as far as possible to the start end of the swing sorting shelf by processing while processing the product toward the rear and the No. 2 reduction processed product while moving forward. To improve the sorting effect.

  The present invention has taken the following technical means in order to solve the above-described problems. That is, the present invention described in claim 1 includes a handling chamber (2) that pivots a handling cylinder (1) and a processing chamber (11) that pivots a processing cylinder (10). In the case where the axial direction of the processing cylinder (10) is parallel to each other, the processing cylinder (10) receives a part of the processed material from the start end side of the processing chamber (2) and sends it backward. A first processing unit (10A) that performs processing, and a second processing unit (10B) that receives and processes the second reduced processed product after sorting, and forwards the first processing unit (10A) and the first processing unit (10A). 2 The processing object processed by the processing part (10B) is configured to drop downward from an intermediate position of the processing chamber (11) or a position closer to the starting end side.

  A part of the processed material such as a piece of cut generated on the start end side of the processing chamber 2 is sent to the front side in the processing chamber 11 and is subjected to a grain removal process while being sent rearward by the first processing unit 10A of the processing cylinder 10. The In addition, the second reduced product after sorting is reduced to the rear side in the processing chamber 11 via the second reduction device 36 and is subjected to a degranulation process while being sent forward by the second processing unit 10B of the processing cylinder 10. . Then, the processed material such as sawdust processed by the first and second processing units is dropped from the intermediate position of the processing chamber or the position near the starting end side to the starting end side of the swing sorting shelf 30 below through the discharge port 13. The

  Accordingly, the processed material dropped from the receiving net 12 and the discharge port 13 of the processing chamber 11 is received as much as possible at the starting end side of the swing sorting shelf 30 and is subjected to sorting processing through a long sorting process to improve sorting performance. .

  According to a second aspect of the present invention, in the first aspect of the present invention, the introduction hole (4) for guiding a part of the processing object into the processing chamber (11) is provided on the side surface on the start end side in the handling chamber (2). And the mesh of the introduction hole (4) is set to be larger than the mesh of the threshing receiving net (3) that is stretched below the handling cylinder (1).

  Unlike the one having a large opening, the introduction hole portion 4 is of a size larger than the mesh size of the handling chamber receiving network 3, so that the processing object can be concentrated and sent into the processing chamber at a stretch. Since it is sent while being processed by the threshing resistance between the threshing receiving net 3 and the tooth handling, the load in the processing chamber 11 can be reduced and the processing can be performed effectively.

  According to the first aspect of the present invention, the threshing load in the processing chamber 2 is received in the processing chamber 11 in order to receive and process the processed product from the starting end side of the processing chamber 2 and the second reduced processed product after sorting. However, the first and second processing parts 10A and 10B of the processing cylinder 10 have the processing object from the start end side of the processing chamber 2 directed rearward, and the second reduction processing object from the processing chamber 2 has moved forward. The processing object such as sawdust falls from the intermediate position of the processing chamber 11 or the position closer to the start end to the lower swing sorting shelf so that it is received at the start end of the swing sorting shelf. Thus, the sorting process is performed through a long sorting process, and the harvest loss in which the grains are discharged out of the machine can be reduced to improve the efficiency of the threshing treatment work.

  Further, according to the present invention of claim 2, the effect of the invention according to claim 1 is achieved, but the degree of the introduction hole portion 4 from the handling chamber 2 to the processing chamber 11 is set to the degree of the threshing receiving net 3. Since it is larger than the mesh size, the processed material is less likely to be concentrated and sent into the processing chamber 11 and is sent while being processed by the degranulation resistance between the threshing receiving net 3 and the tooth-handling. Can be reduced, and the efficiency of the threshing treatment work can be improved.

Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the configuration of the threshing apparatus shown in FIGS. 1 and 2 will be described.
A receiving net 3 is stretched along a lower half periphery of a handling chamber 2 in which the handling cylinder 1 is pivoted. Reference numeral 7 denotes a handling cylinder cover that covers the upper part of the handling chamber 2, and is configured to be able to swing open and close around an axis Q parallel to the handling cylinder axis direction.

  A feed chain 8 that sandwiches and conveys the cereal grains and a sandwiching rail 8a that is provided on the upper side of the handling chamber 2 are disposed on the mouth side. The sandwiching rail 8a is mounted on the barrel cover 7 side and swings and opens together with the cover. A dust exhaust port 9 is provided on the terminal side of the handling chamber 2 to drop a dust treated product including a large amount of sawdust and untreated material downward.

On one side of the handling chamber 2 opposite to the feed chain 8 side, a processing chamber 11 in which a processing cylinder 10 is pivoted is arranged in parallel so that the front and rear handling cylinders 1 and 10 are parallel to each other.
The processing cylinder 10 is reduced from the first processing unit 10 </ b> A that receives a part of the unprocessed material from the starting end side of the processing chamber 2 and processes the processing cylinder 10 while feeding it backward, and from the processing chamber 2 through the second reduction device 36. The second processing unit 10B that receives the second reduction processing product and processes it forward is processed, and the processing product processed by the first and second processing units 10A and 10B is close to the start end side of the processing chamber 11. In order to drop downward, that is, to discharge from a discharge port 13 provided by opening the lower wall on the front side from the middle portion of the receiving net 12. A jumping plate 14 is provided between the spike-cutting tooth group 10a of the first processing unit 10A and the second processing tooth group 10b of the second processing unit 10B. The processed product is discharged from the discharge port 13 to the start end side of the swing sorting shelf by the jump plate 14.

  In addition, the second processing tooth group 10a of the second processing unit 10B is provided with a dust feeding lead angle θ, and the ear cutting processing tooth group 10a of the first processing unit 10A is not provided with a dust feeding lead angle. By providing the dust feed lead angle, the second processing unit that processes the second product containing a large amount of straw dust and grains can eliminate the stagnation and clogging of the processed material, and can efficiently perform the degranulation processing action. On the other hand, if the first processing part with a short front-rear length is provided with a dust feed lead angle, the dust will be sent without sufficient treatment, so there is no dust feed angle and while sufficiently loosening the ears. It can be processed. In addition, the spike-cut tooth group is provided with a higher pitch between the tooth teeth than the second tooth group, thereby further enhancing the processing function.

  A dust feeding guide plate 15 is provided on the inner wall of the processing chamber 11 corresponding to the first processing section 10A, and is configured so that the dust can be smoothly fed backward. Further, the dust feed angle of the dust feed guide plate 15 is smaller than that of the dust feed guide plate 26 on the dust removal treatment cylinder side because the treatment process on the first processing unit 10A side is shorter than the dust removal treatment cylinder 21 side. Thus, processing is performed while slowly feeding.

  The receiving network 12a on the first processing unit 10A side in the receiving network 12 is configured with a perforated network body, and the receiving network 12b on the second processing unit 10B side is configured with a non-porous plate. As shown in FIG. 11, if the partition resistance plate 16 that wraps with the cut end processing teeth 10 a is provided on the receiving net 12 a on the first processing unit 10 </ b> A side, transfer resistance is given to a coarse processed product. A further separation action is promoted, and the degranulation process can be performed with good reliability. In addition, if the mesh size of the receiving holes of the receiving net 12a is made larger than the mesh size of the receiving net 3 of the handling room, the filtration efficiency of the grains that are made into single grains in the first processing unit is increased, and the processing burden is reduced. Can be reduced.

The ejecting plate 14 is installed closer to the front side of the width of the discharge port 13, and the second processing unit 10 </ b> B side with a large amount of processed material is configured to be long in the front-rear direction.
Further, the first processing unit 10A and the second processing unit 10B of the processing cylinder 10 have the same diameter on the same axis and have a smaller diameter than the dust processing cylinder 21 described later.

  The receiving network 3 of the handling chamber 2 is composed of an upper receiving network 3U and a lower receiving network 3D, and the upper receiving network 3U can be inserted and fixed to the lower receiving network 3D with pins 3p. In the upper part of the start end side of the handling chamber 2, an introduction hole portion 4 that guides a part of untreated material such as a piece of spike into the processing chamber 11 on the upper receiving net 3 </ b> U side is provided. It is set as the structure of the scale H3 made larger than (H1 <H3). Further, the mesh of the receiving network is larger than the normal mesh H1 of the lower receiving network 3D, and the mesh H2 of the upper receiving network 3U is made larger. Is larger than H2 (H1 <H2 <H3). Even if the upper receiving net has a larger filtering hole size than the lower receiving net, the filtering efficiency is lower than that of the lower receiving net. Therefore, the filtering efficiency can be increased by increasing the size.

  In addition, in the structure of the said introduction hole part 4, as shown in FIG. 12, it is set as the structure which consists of the some partition plate 4a of the vertical direction (cylinder rotation direction), and the steel wire 4b of a horizontal direction (cylinder cylinder direction). Moreover, unlike the crimp net configuration, the partition plate 4a protrudes higher toward the handling cylinder side than the wire 4b, so that it is difficult to catch the spikes and the like, and can be introduced into the processing chamber side easily and smoothly. .

  Of the dividers 5a, 5b, 5c provided on the inner wall surface of the receiving net 3 along the barrel rotation direction, the foremost part of the divider 5a is immediately after the introduction hole 4 of the upper receiving net 3U and the processing. By making the end portion of the first processing unit 10 </ b> A of the trunk 10 substantially the same as the front and rear positions, it is possible to reliably lead the ear breakage that occurs on the start end side of the handling chamber to the first processing unit in the processing chamber. In addition, the partition plate 4a of the introduction hole portion 4 has a protrusion margin lower than that of the first partition metal 5a so as to prevent an extreme load in the handling chamber from being applied.

  In addition, a dust removal treatment cylinder chamber 22 having a dust removal treatment cylinder 21 provided with treatment teeth 20 on the outer periphery on the same axis as the inner shaft is configured and provided behind the treatment cylinder 10. Spiral-shaped intake vanes 23 fixed to the start end of the dust treatment cylinder 21 intervene in the dust feed path from the portion corresponding to the dust discharge port 9 at the end of the handling chamber to the start end of the dust treatment chamber 22. Thus, it is possible to easily take in the dust in the dust processing chamber 22. A discharge blade 24 is provided at the end of the dust removal treatment cylinder 21, and the dust discharged to the end of the dust removal treatment chamber 22 is transferred from the waste discharge port 25 at the end of the dust treatment chamber by the discharge blade 24 to be described later. The swing sorting device 30 is configured to discharge to the end of the sorting shelf and out of the machine.

In the dust removal treatment chamber 22, several dust feed guide plates 26, 26,... Are provided to be inclined at predetermined intervals so as to feed and guide the processed material toward the rear in the axial direction.
Dust processing material taken into the dust processing chamber 22 from the end of the processing chamber is processed by the processing teeth 20 on the outer periphery of the processing cylinder while being transported backward by the dust feeding guide plate 26, and leaks from the filtration hole of the processing receiving net. It is returned to the swing sorting shelf.

  A swing sorting device (swing sorting shelf) 30 is installed below the handling chamber 2 so as to be swingable, and further below that, in order from the upper side of the sorting direction, the red pepper 31 and the first transfer spiral. 32, the second transfer spiral 33, and a suction dust exhaust fan 34 of a one-side suction system are provided above it to constitute a sorting chamber. The first cerealing device 35 lifts the grains collected by the first transfer spiral 32 and stores them in the Glen tank G. The second reduction device 36 is configured to return the second item collected by the second transfer spiral 33 to the second processing unit 10 </ b> B in the processing chamber 11.

  The swing sorting device (swing sorting shelf) 30 is configured to receive the processed product after the threshing process from the handling room and screen the screen while swinging and transferring it. 38 and Strollac 39 in this order, and a grain sheave 40 is provided below the chaff sheave 38, and the handling chamber 2 and It is configured to receive a processed material leaked from the processing chamber 11 and perform a sieve sorting process while swinging and transferring the processed material. A dust collecting plate 41 is provided on the transfer shelf 37 to bring the processed material to the center side.

  The discharge port 13 of the processing chamber 11 is on the transfer shelf 37 on the start end side of the swing sorting shelf, and is provided in front of the dust collecting plate 41 so that the processed material discharged from the discharge port can be discharged. It is possible to spread over the entire width of the swing shelf and enhance the sorting effect.

  When the culm harvested by the reaping part is supplied to the threshing device, first, the culm is held in the feed chain 8 while being fed by the stock chain, and the tip portion is supplied into the handling chamber 2. Threshing action is received by the rotating barrel 1. The threshing processed material processed in this way is carried around by the rotating handling cylinder 1 and further subjected to a threshing treatment action, leaks from the receiving net 3 and reaches the swing sorting device 30 in the sorting chamber. Subject to rocking selection.

  In this case, the processed product that has been threshed on the start end side of the handling chamber falls on the transfer shelf 37 and is oscillated rearward to reach the chaff sheave 38. In addition, the dust disposal product that has reached the end of the handling chamber falls on the chaff sheave 38 below from the dust outlet 9, and is sent into the dust disposal chamber 22 through the dust feeding path and is disposed in the dust disposal cylinder 21. It is divided into what is processed by. The dust-removed product on the chaff sheave 38 is subjected to a wind selection action while leaking a sorting interval between the plurality of sheave plates constituting the chaff sheave 38. What leaks from the chaff sheave 38 falls on the grain sieve 40 and is subjected to a wind selection action while being screened. At this time, the Kara 31 is sorted by blowing the raised sorting wind into the sorting chamber, and is sorted by the suction action by the suction dust exhaust fan 34.

  In this way, the processed material is sorted while receiving the cooperative action of the oscillating sorting action and the wind sorting action by the sorting wind, and sorted into the first (fine grain), the second, and the dust. Then, after the first product is screened and sorted by the grain 40, it is dropped and collected in the receptacle of the first transfer spiral 32, taken out of the machine, and stored in the Glen tank G. The second product is cerealed from the second transfer spiral 33 by the second reduction device 36, returned to the second processing unit 10B of the processing cylinder 10 in the processing chamber 11, and processed while being sent forward. The dust is sucked by the suction dust fan 34 and discharged to the outside of the machine, and the sawdust that has reached the straw rack 39 is discharged from the shelf end to the outside of the machine.

  On the other hand, a part of unprocessed material such as a piece of spike that occurs on the start end side of the treatment chamber is introduced from the introduction hole 4 to the first treatment unit 10A of the treatment cylinder 10 in the treatment chamber 11, and the piece of spike treatment teeth 10a. And the receiving net 12a are crushed while being sent backward. The single grain processed here is filtered from the receiving net 12a, and the processed material such as sawdust is combined with the second processed material from the second processing unit 10B together with the swing sorting shelf below the discharge port 13. It is dropped onto the starting end side of 30, that is, onto the transfer shelf 37. On the other hand, the dust-removed material taken into the dust-removing treatment chamber 22 from the end of the handling chamber is processed by the processing teeth 20 on the outer periphery of the dust-removing treatment barrel 21 while being transferred backward by the dust-feeding guide plate 26. It leaks through the filter hole of the receiving net and is reduced onto the chaff sheave 38. When reaching the end of the dust removal chamber 22, the dust is discharged onto the Strolack 39 and out of the machine by the discharge blade 24 at the end of the dust removal cylinder 21.

  In addition, the waste after threshing is carried out rearward by the waste transporting device 43 and cut into a predetermined length under the action of the waste cutter 44.
