It is inserted into the handling chamber 66. A handling drum 69 pivoted in the handling chamber 66 has a large number of teeth 69a provided on the surface thereof, and the power from the engine is transmitted via a cutting / threshing clutch 27 (FIG. 9) by a drive mechanism (not shown). Then, it rotates in the direction of arrow B in FIGS. The cereal with the grain inserted into the handling chamber 66 is sandwiched between the feed chain 14 that moves along the rail guide 14c and the feed chain nip 14a that is biased by the spring 14b. While being transported in the direction of arrow A in FIG. 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. 7) and is received by the swing shelf 51.

  Since the swing shelf 51 swings up and down and back and forth by the operation of a swing shelf drive mechanism (not shown), the workpiece is moved in the direction of arrow D (FIGS. 4 and 5) and receives air from the tang 79. Grain that has been subjected to wind sorting and has a high specific gravity passes through the sheave 53 and the sorting net 63 in the direction of arrow E, and is accumulated on the first shelf board 64, and from the first spiral 65 to the first milling cylinder 16 (FIG. 1). After that, it is conveyed to the Glen tank 30. 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 move on the sheave 53 in the direction of arrow D, The second small grain on the rack 62 falls 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 (FIGS. 4 and 4). 5).

  The second kernel is a mixture of normal kernels, branch stems, crumbs and scorpion grains in which normal grains are stabbed in the crumbs. It is pumped up in the direction of arrow H (see FIGS. 4, 5, and 7) by a milled helix (not shown) and discharged upward from the second processing chamber 67 to 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 in FIG. 7 by a driving device (not shown). While the second grain proceeds in the direction of the arrow I (FIGS. 4 and 5) while colliding with the numerous treatment teeth 70a (FIG. 5) and the spiral 70c (FIG. 4) planted in the second treatment cylinder 70. The separation of the second grain and the removal of the branch infarction are performed, and a part of the workpiece passes through the second treatment trunk receiving net 75 in the direction of arrow C2 (FIGS. 4 and 5) and swings. Most of the objects to be processed fall on the shelf 51 and are sent from the end of the second processing chamber 67 to the second processing cylinder air blowing blade 70b to the swing shelf 51 in the direction of arrow C3 (FIGS. 4 and 5). It falls and merges with the object to be processed from the handling chamber 66.

  The feature of the present embodiment is that the dust disposal chamber 68 is provided on the rear side of the handling chamber 66 at an adjacent portion, and the workpiece transport direction end portion of the handling chamber 66 and the workpiece treatment in the dust disposal chamber 68 are conveyed. An opening to be a dust removal processing chamber inlet 68a is provided at a connection portion with the direction start end portion.

  Furthermore, another feature of the present embodiment is that the second treatment chamber 67 is provided below the dust removal treatment chamber 68 and the object to be treated that leaks from the dust treatment chamber 68 is located at the rear of the second treatment chamber 67. It is configured to be transferred to the front of the second processing chamber 67.

  Among the objects to be processed that have reached the terminal end of the object to be processed in the handling chamber 66, short objects such as scraps are thrown into the direction of the arrow A2 (FIG. 6) from the dust discharging chamber inlet 68a and are subjected to dust processing. It enters the chamber 68 and is processed while being conveyed in the direction of arrow K (FIG. 6) by the spiral 71a of the rotating dust exhausting cylinder 71 in the dust exhausting chamber 68.

  Leakage in the processing object mainly composed of sawdust including a small amount of grain that has entered the dust disposal chamber 68 is transferred from the receiving net 76 (FIG. 7) to the second processing cylinder 70 of the second processing chamber 67. The second processing cylinder 70 is rotated by the spiral 70 c (FIG. 4) or the processing teeth 70 a (FIG. 5) provided around the rear side of the second processing cylinder 70 by the rotation of the second processing cylinder 70. It is processed while being conveyed forward, passes through the receiving net 75 provided below the second processing cylinder 70 in the direction of arrow C3, and is sent onto the transfer shelf 51a of the swing shelf 51.

  In the conventional threshing apparatus, the leakage from the dust processing chamber 68 is not sent to the second processing chamber 67, but is recovered in its entirety on the swing shelf 51. Therefore, the grains and straws on the swing shelf 51 are collected. It could not be said that sorting with waste etc. could be performed efficiently.

  However, with the configuration of the present embodiment shown in FIGS. 4 to 7, the grains processed in the dust removal processing chamber 68 are recovered to the transfer shelf 51 a of the vibration shelf 51 and quickly recovered to the first spiral 65. Threshing loss is reduced.

  In the threshing device 15, the workpiece leaked from the dust processing chamber 68 to the second processing chamber 67 is transported to the front of the second processing chamber 67 by the second processing cylinder 70 and is processed into a single grain. According to this configuration, branch infarct grains and cut grains including single grains leaked from the dust removal processing chamber 68 are directly made into single grains by the second processing cylinder 70, and are swung from the receiving net 75 in front of the second processing chamber 67. It is sent to 51 and there exists an effect that a grain can be collected efficiently.

  Further, while the rear end portion of the dust removal processing cylinder 71 is extended to a position reaching the rear wall surface 15a of the threshing device 15, the rear end portion of the second processing cylinder 70 reaches the rear wall surface 15a of the threshing device 15. One of the features of this embodiment is that the length is not set.

  In general, among the workpieces processed by the dust disposal cylinder 71, there are many grains that leak from the receiving net 76 in the front part of the dust disposal cylinder 71, but there are very few grains in the rear part, and conversely, the leakage of the sawdust. The bottom increases rapidly. Therefore, the ratio of the grain collect | recovered to the 2nd process cylinder 70 from the front part of the dust removal process cylinder 68 can be raised by setting it as the said structure.

  As shown in FIGS. 4 to 6, a crossflow fan 91 is provided at the rear of the threshing device 15, and among the dust generated in the threshing device 15 including the dust processing chamber 68, Air containing dust is sucked by blowing air by rotation of the cross-flow fan impeller 91a, blown out in the direction of arrow L from the cross-flow fan outlet 91b (FIGS. 4 and 5), and discharged to the outside of the combine 1.

  Of the dust that has fallen as shown by the arrow M (FIGS. 4 and 5) from the chamber where the cross-flow fan 91 falls to the end of the swing shelf 51, slightly longer waste is received by the Strolack 62, and the swing shelf. As shown by the arrow F, it is discharged from the end portion of the swing shelf 51 by the swinging motion of 51 and the air blowing force of the Kara 79 and discharged to the field. Further, among the dust particles, those having a small diameter and heavy specific gravity, such as the second grain and the third grain, pass through the Strollac 62 or the sheave 53 at the end of the swing shelf 51 in the direction of the arrow G, and the second shelf board. It falls to 85 and processed in the second processing chamber 67 again.

  The threshing cereals (slags) that have been threshed in the material to be processed that have traveled in the direction of arrow A in FIG. 6 and have reached the end of the handling chamber 66 are shown in FIG. It is transported in the A1 direction and put into the waste disposal chamber 95. As shown in FIG. 8, the entrance portion of the waste disposal chamber 95 is provided with an entrance damper 95a that goes in and out in the horizontal direction to open or close the entrance portion, and when the entrance damper 95a is opened, the waste is indicated by an arrow. It falls in the P direction (FIG. 8) and is cut by the scissors cutters 92 and 93. The scissors cutters 92 and 93 are rotationally driven at rotational speeds controlled by drive actuators M3 and M4, respectively. The cuttings finely cut by the cutting cutters 92 and 93 are diffused in the axial direction (in the width direction of the combine 1) by the spiral diffusion means 94 that is rotationally driven by the driving actuator M5, and dropped and released to the field.

  In addition, when the entrance damper 95a of the waste disposal chamber 95 is closed at the position indicated by the reference line in FIG. It is set as the structure which falls in the arrow Q direction and is discharge | released to a farm field, without cut | disconnecting.

In the threshing apparatus 15 according to the embodiment of the present invention, the cover 68c provided on the upper surface of the dust removal processing chamber 68 is configured to be openable and closable as shown in FIGS.
The upper cover 66b of the handling chamber 66 is openable and closable in the upper wall surface of the conventional combine threshing device 15, but the dust removal processing cylinder 71 is disposed relatively below the rear side of the handling cylinder 69. Therefore, for maintenance of the dust removal processing cylinder 71, the operator has to open the handling chamber upper surface cover 66b and work in a posture of crouching. The dust removal cylinder was easily entangled with waste, and the waste removal work was a burden.

  However, in the embodiment shown in FIG. 7, the dust removal processing chamber 68 is disposed near the upper surface of the threshing device 15. Therefore, an upper cover 68c is provided on the upper surface of the dust removal processing chamber 68, and as shown in FIG. Is configured to be openable and closable. Therefore, the waste removal work entangled with the dust removal processing cylinder 71 can be easily performed. Further, maintenance of the dust removal processing cylinder 71 such as replacement of the spiral 71a of the dust collection processing cylinder 71 can be easily performed.

  As a combine according to an embodiment of the present invention, a synchronized transfer device 21 that supplies and conveys cereals harvested in synchronization with the rotational speed of the engine 28 to the threshing device 15 (the supply that takes over cereals from the reaping device 6 to the threshing device 15) In the case of using a combine equipped with a transport device (not shown) and the like, when the cereal transport speed of the synchro transport device 21 reaches a certain set value or more, the rotational speed corresponding to the speed V1 of the feed chain 14 is accordingly increased. A gear transmission mechanism 23 having a feed chain rotational speed control clutch 22 that can be changed to the speed V2 is used.

  The gear transmission mechanism 23 is shown in FIG. 9, the flow of the rotational speed control of the feed chain 14 is shown in FIG. 10 (a), and the relationship between the vehicle speed and the rotational speed of the feed chain 14 is shown in FIG. 10 (b). The gear transmission mechanism 23 is provided with a switching lever 25 and a lever operating motor 26 for switching the rotation speed of the feed chain 14 between the speed V1 and the speed V2. Further, the synchro transport device 21 and the feed chain 14 are connected to the engine 28 via a mowing / threshing clutch 27 for driving the mowing device 6.

When a vehicle speed sensor (not shown) is at or below a predetermined vehicle speed, the rotational speed control clutch 22 of the feed chain 14 is connected to the speed V1 side, and the vehicle speed sensor detects that the vehicle speed is higher than the predetermined vehicle speed. The feed chain rotational speed control clutch 22 is driven and controlled by the motor 26 so as to switch to the speed V2 side.

  At this time, when the rotation speed of the feed chain 14 is a speed V2 higher than the speed V1, the cereal transport speed of the synchro transport device 21 is faster than or equal to the maximum speed. . By using such a synchro conveying device 21, when the cereal is handed over from the reaping device 6 to the threshing device 15, the cereal conveying posture is not disturbed or clogged.

Moreover, as the layer thickness of the cereals at the entrance of the handling chamber 66 increases, the resistance also increases, and there is a problem that the occurrence of cuttings and clogging is likely to occur due to disturbance of the threshing posture.
Therefore, as shown in FIG. 11, the rotation speed of the feed chain 14 may be set to a constant value that is faster than the maximum value of the grain transport speed of the synchro transport device 21. With such a configuration, even if the layer thickness of the cereal at the entrance of the handling chamber 66 is increased, the threshing device 15 is not disturbed at any speed range, and the rotation speed of the feed chain 14 is synchronized. Since the speed of the cereal conveying speed of the transport device 21 is faster, the thickness of the cereal layer in the synchro conveying device 21 is larger than the thickness of the cereal layer in the portion of the feed chain 14, so And problems such as clogging of cereals do not occur.
