  4 is a partially cutaway side cross-sectional view of the combine threshing device 15, FIG. 5 is a plan cross-sectional view of the threshing device 15 as viewed from the line BB in FIG. 4, and FIG. It is elevation surface sectional drawing of the threshing apparatus 15 of C line arrow.

  The grain husks harvested by the reaping device 6 are adjusted in the handling depth by the cereal conveyance and adjusting device attached to the reaping device 6 and inserted into the handling chamber 66 which is the main threshing portion of the threshing device 15. A handling drum 69 pivoted in the handling chamber 66 has a large number of teeth 69a on its surface, and is rotated in the direction of arrow B in FIGS. To do. Grains with grains inserted in the handling chamber 66 are transferred in the direction of arrow A in FIG. 5 by the moving feed chain 14, while the teeth 69 a and the handling net 74 of the handling drum 69 rotate in the direction of arrow B. Is threshed by the interaction. The object to be processed (grains and sawdust) separated from the cereals passes through the handling net 74 in the direction of arrow C1 (FIG. 6) and is received by the swing shelf 51.

  The swing shelf 51 is composed of a transfer shelf arranged below the handling net 74 of the handling chamber 66, an upper sheave 53 arranged behind it, a sorting net 63 below it, and a Strollac 62 arranged at the rearmost end. However, a feature of this embodiment is that the transfer shelves 55 and 56 each having a plurality of triangular sorting plates 55a and 56a are configured in two upper and lower stages. The upper transfer shelf 55 is disposed in front of the sheave 53, and the lower transfer shelf 56 is disposed in front of the sorting net 63. In addition, the lower transfer shelf 56 is located closer to the front side of the threshing device 15 than the upper transfer shelf 55 so that a recovery port for recovering the workpiece leaking from the handling chamber 66 is opened above the upper transfer shelf 55. Arrange it to be long. Then, the width of the recovery port for recovering the workpiece that leaks through the handling net 74 of the handling chamber 66 in the lower transfer shelf 56 is set to a width that is approximately 1/3 of the entire length of the handling net 74.

  In this way, the lower transfer shelf 56 is arranged to be longer in the forward direction than the upper transfer shelf 55, so that the leakage from the handling net 74 is about 1/3 of the entire length of the handling net 74. It is based on what was found from the experimental data shown in FIG. Further, the upper transfer shelf 55 is arranged below a second processing chamber 67 which will be described later, and can receive the second processed material.

  The grain that has been threshed in the early stage of threshing that leaks in about 1/3 of the area in front of the handling net 74 is a single grain and does not contain impurities, so there is no need to coarsely sort on the sieve 53, and the direct sorting net 63 The wind can be selected by blowing air from the tang 79, which will be described later. In addition, 50% of the leakages are collected on the lower transfer shelf 56 and the upper transfer shelf 55, respectively, and the grains are leveled on the transfer shelves 55 and 56 to improve the sorting performance.

  Further, since the swing shelf 51 swings in the up / down / front / rear direction by the operation of the swing shelf drive mechanism (not shown), the object to be processed leaks onto the lower transfer shelf 56 while moving in the arrow D direction (FIG. 4). The grain having a high specific gravity passes through the sorting net 63 in the direction of arrow E, is accumulated on the first shelf 64, and is conveyed from the first spiral 65 to the grain tank 30 via the first groin cylinder 16. The grains stored in the Glen tank 30 are conveyed to the outside of the combine 1 via the augers 18 and 19.

  Among the objects to be processed on the swing shelf 51, the lighter ones are blown off by the swing action of the swing shelf 51 and the air blown by the fan 79 a of the Karatsu 79 and are directed in the direction of arrow D from the upper transfer shelf 55 toward the sheave 53. The second small grain on the Strollac 62 leaks in the direction of arrow G and is collected on the second shelf 85, and is conveyed to the second lifting cylinder 87 by the second spiral 86. (FIG. 4).

  The second kernel (sometimes called the second product) is a mixture of normal kernels, branch boughs, sawdust and scorpion grains with normal kernels in the waste. The inside of the whipping cylinder 87 is lifted in the direction of arrow H (see FIG. 4) by a second whipping cylinder spiral (not shown), and discharged from the second processing chamber inlet to above the second processing chamber 67. . The second processing cylinder 70 pivoted on the lower portion of the second processing chamber 67 is rotated in the direction of arrow J by a driving device (not shown). The second kernel is separated from the second kernel and branch branch while traveling in the direction of arrow I (FIGS. 4 and 5) while colliding with a number of processing teeth 70a planted in the second processing cylinder 70. The part of the object to be processed passes through the receiving net 75 provided below the second processing cylinder 70 and leaks to the sorting chamber 50, and most of the object to be processed is the upper transfer shelf. 55 is sent in the direction of the sheave 53, and the grain passes through the sheave 53 and the sorting net 63 and is first collected in the spiral 65.

  Thus, by recovering the second item on the upper transfer shelf 55 and reprocessing with the sheave 53, the separation between the grain and the sawdust becomes good.

  At this time, as shown in the perspective view of the main part of the threshing device 15 in FIG. 8, the lower side of the outlet of the second processing cylinder 70 of the upper transfer shelf 55 is made to protrude forward compared to the other parts. good. This is because, when the second processing cylinder 70 is extended to the front of the handling chamber 66 and the processing configuration is lengthened to improve the capacity, the upper transfer shelf 55 below the upper transfer shelf 55 projects forward from the other parts. When the start end receiving portion 55 c and the bent piece 55 d formed by bending the left end portion of the receiving portion 55 c upward are formed, the second processed material processed by the second processing cylinder 70 leaks to the lower transfer shelf 56. Therefore, the material is collected on the upper transfer shelf 55 and roughly sorted by the sheave 53, so that the sorting property of the object to be processed is improved.

  Further, the upper transfer shelf 55 is rotatable in the direction of the arrow Y in FIG. 4 with the end portion on the sheave 53 side as a rotation fulcrum, and the upper transfer shelf is brought into contact with the lower transfer shelf 56 by contacting the front end portion of the upper transfer shelf 55. Both the state where the leakage from the handling net 74 is collected only at 55 and the upper transfer shelf 55 are controlled to rotate in the direction to open the grain collection port of the lower transfer shelf 56, so that both the upper and lower transfer shelves 55, 56 It is switched to the state to be recovered.

  As a result, when the grain flow rate is small, the entire amount is collected on the upper transfer shelf 55, passed through the sheave 53, and sorted by the sheave 53, so that the number of sorting increases by one sheave sorting, and the sorting can be improved. On the other hand, when the grain flow rate is large, it is possible to improve the capacity by selecting both the upper and lower transfer shelves 55 and 56.

  In addition, the rotation of the front end of the upper transfer shelf 55 is related to the combine vehicle speed, and as the vehicle speed increases, the grain recovery amount in the lower transfer shelf 56 is increased, and the increase in the throughput of the sheave 53 is also suppressed. it can.

  As the vehicle speed increases, the amount of grain that leaks onto the upper and lower transfer shelves 55 and 56 increases, and the generation of swarf also increases. At this time, the mixing amount of grains and sawdust in the workpiece transferred from the upper transfer shelf 55 to the sheave 53 increases, and the sorting loss amount in the sheave 53 increases. In order to prevent this, when the grain flow rate is increased, an increase in the number of objects to be processed on the sheave 53 is suppressed, and the front end of the upper transfer shelf 55 is raised to improve the sorting performance, and the recovery port of the lower transfer shelf 56 is raised. Is greatly opened to increase the amount of leakage of the workpiece to the lower transfer shelf 56.

  The drive control of the vertical movement drive motor 57 of the upper transfer shelf 55 is performed based on a vehicle speed detection value of a vehicle speed sensor (not shown) and a rotation angle detection value of a potentiometer 58 for controlling the rotation of the upper transfer shelf 55.

  Furthermore, the upper transfer shelf 55 is driven so that the flow rate of the workpiece on the upper transfer shelf 55 is detected by the flow sensor 59 and the processing amount of the upper transfer shelf 55 can be changed according to the flow rate of the workpiece. The drive control of the control motor 57 can also be performed.

  For example, when the amount of the processed material on the lower transfer shelf 56 becomes a set value or more, the upper transfer shelf 55 so that the collection port of the lower transfer shelf 56 becomes small so that a large amount of the processed material is distributed to the upper transfer shelf 55. By lowering the front end of the sheet so that the processing load on the lower transfer shelf 56 does not exceed the set value, it is possible to stabilize the sortability of the object to be processed.

  Since the grain passing over the upper transfer shelf 55 leaks from the sheave 53, the sorting property is relatively good because the processing object selection process is performed once more than the grains collected in the lower transfer shelf 56. Therefore, when the processing load on the lower transfer shelf 56 exceeds the set value, the front end portion of the upper transfer shelf 55 is lowered so as to reduce the amount of workpieces leaking to the lower transfer shelf 56.

  The inclination angle (mesh) of each sheave plate of the sheave 53 may be changed in conjunction with the control of changing the area of the grain collection port of the lower transfer shelf 56 by the vertical movement of the front end portion of the upper transfer shelf 55. .

  This is because when the area of the grain collection port of the lower transfer shelf 56 is reduced and a large amount of processing object is supplied to the upper transfer shelf 55, the amount of processing in the sheave 53 is also increased. This is because the ability is improved.

  In addition, the control of changing the area of the grain collection port of the lower transfer shelf 56 is performed by detecting the culm of a culm sensor (not shown) provided in the reaper 6 during vertical movement of the reaper 6 and turning of the combine corner. , You can go.

  Since the amount of the processed material in the threshing device 15 is reduced after the harvesting of the harvested product is finished, when the completion of the cutting is detected by the upward movement of the harvesting device 6, the area of the grain collection port of the lower transfer shelf 56 is reduced. Thus, the processing amount in the sheave 53 is increased.

  Further, when the combine is turning the corner of the field, the upper transfer shelf 55 is rotated in a direction to close the area of the grain collection port of the lower transfer shelf 56, and the entire amount of the processing object is transferred to the upper transfer shelf 55. To send.

  Furthermore, when the culm sensor is off, cereal harvesting is not performed, and therefore the upper transfer shelf 55 in a direction to close the area of the grain recovery port of the lower transfer shelf 56 in conjunction with the turning off of the cereal sensor. Is rotated to feed the entire amount of the object to be processed onto the upper transfer shelf 55. Further, when the culm sensor is on, the culm is being harvested, so that the upper transport shelf 55 is rotated in the direction to open the grain recovery port of the lower transport shelf 56 in conjunction with the on of the culm sensor. The object to be processed is also fed onto the lower transfer shelf 56 by performing dynamic control.

  The threshing cereals that have been threshed in the object to be processed that have traveled in the direction of arrow A in FIG. 5 and have reached the end of the handling room 66 are in the direction of arrow A1 shown in FIG. It is transported and put into the waste disposal chamber 95.

  Among the objects to be processed that have reached the end of the object to be processed conveyance direction of the handling chamber 66, short objects such as scraps are thrown into the direction of the arrow A2 (FIG. 5) from the dust collection chamber inlet 68a and discharged. It enters the dust treatment chamber 68 and is processed in the dust removal treatment chamber 68 while being conveyed in the direction of arrow K (FIGS. 4 and 5) by the spiral 71a of the dust removal treatment cylinder 71 rotating.

  Leakage (grains) in the processing object mainly composed of sawdust containing a small amount of grain entering the dust disposal chamber 68 leaks from the receiving net 76 (FIG. 4) onto the swing shelf 51. Then, it is guided to the Strollac 62 provided on the swing shelf 51 and sent from the second shelf board 85 to the second processing chamber 67 via the second lifting cylinder 87.

  The Strollac 62 attached to the swing shelf 51 has a rotating base attached to the rear portion of the swing shelf 51, and has a configuration in which the front of the Strollack 62 is a free end. It is possible to increase the wind sorting ability of firewood and wood scraps than before.

  The second processing cylinder 70 and the dust removal processing cylinder 71 on the same axis are driven by a driving force from the engine via a pulley, although not shown.

  As shown in FIGS. 4 and 5, a crossflow fan 91 is provided at the rear part of the threshing device 15. Then, air containing dust is sucked by blowing air by rotation of the crossflow fan 91, blown out in the direction of arrow L from the outlet of the crossflow fan, and discharged to the outside of the combine 1.

  Among the dust that has fallen from the dust removal processing chamber 68 to the end of the swing shelf 51 as indicated by an arrow M (FIG. 4), those having a small diameter and a heavy specific gravity, such as second and third grains, 51 passes through the end portion 51 of the stroller 62 or the sheave 53 in the direction of arrow G, leaks to the second shelf 85, and is again processed in the second processing chamber 67.

  Of the dust that has fallen from the dust removal processing chamber 68 to the end of the swing shelf 51 as indicated by the arrow M, slightly longer scrap is received by the Strollac 62, and the swing motion of the swing shelf 51, It is discharged from the terminal end of the swing shelf 51 as indicated by the arrow F by the blowing force of the red pepper 79 and discharged to the field.
