Field of the Invention The present invention relates to a threshing apparatus for a threshing machine, and more particularly to a threshing apparatus for a combine or a harvester. 2. Description of the Related Art A conventional threshing machine of this type is disclosed, for example, in Japanese Unexamined Utility Model Publication No. 56-86959.
The handling room with the inner cylinder mounted on the handling cylinder and the processing chamber with the inner processing shaft mounted on the processing cylinder are arranged close to each other, so that the handling cylinder and the processing cylinder rotate in opposite directions. ing. Then, the thresh from the handling room is sent from the end of the handling room to the processing room, while the processed material in the processing room is processed toward the beginning of the handling room (in the direction opposite to the transfer direction of the handling room). While being transported, it is configured to be returned to the starting end side of the handling chamber. In this conventional configuration, the movement of the processed material between the handling room and the processing room is limited to two places. [0004] In recent years, combine harvesters have been increased in size (multi-cutting) for large-scale agriculture, and high-efficiency machines have been demanded. Therefore, as a matter of course, a threshing device mounted on the combine needs to have a high threshing processing capability. The threshing apparatus must have an organically related configuration of the handling room and the treatment room in order to increase the threshing efficiency, and must exhibit a highly efficient threshing process by the synergistic action of the two. [0005] In the conventional threshing apparatus, as seen from the above-mentioned prior art, the threshing product generally has a configuration in which the threshing process reciprocates once between a handling room and a processing room. However, in this case, when a large amount of threshing material is generated in the handling room, it is sent to the processing room immediately,

When an appropriate prime mover is started and the rotational power is transmitted to the threshing machine, the rotating parts of the fuselage are driven and ready to thresh, but the handling cylinder 1 and the processing cylinder 3 are reciprocated as shown by arrows in FIG. Is rotating in the opposite direction. The culm is threshed by the rotating handling drum 1 which is supplied to the handling chamber 2 from the cereal feeding port 8 while being transported while being sandwiched by the feed chain 14. In this way, the grain stem to be threshed is further subjected to threshing action while being carried around by the rotating toothing 12 of the rotating drum 1. Then, the thresh-processed product is obtained by sorting grains, dust and the like into a sorting net 11.
To reach the lower swing sorting shelf 21, while the attached branch branch grains are sent to the processing chamber 4. At this time, the thresh-processed material is transferred to the scraping blades 16a of the processing cylinder 3 from the toothing 12 of the handling cylinder 1 which is rotating in the opposite direction while drawing the trajectory indicated by the arrow in FIG. The material that has jumped out of the chamber 2 is scraped into the processing chamber 4.
The processed material is processed by the processing teeth 17 while being carried around by the processing cylinder 3 in the processing chamber 4. In the threshing process, in the threshing process, grains separated from straw, branch stalks and the like leak from the sorting nets 11 and 15 in both rooms to the sorting room 20 below. In the first half of the handling room 2, the unprocessed material that is continuously processed in the handling room 2 and the processing room 4 increases the threshing processed material in the room, so that the amount sent to the processing room 4 inevitably increases, Then, the amount returned to the handling room 2 from the processing room 4 increases. As described above, the thresh-processed product is transferred to the handling room 2
The processing is carried out while passing through the opening 5 between the processing chamber 4 and the processing chamber 4. In this case, the rotation peripheral speed of the tip of the processing tooth 17 of the processing cylinder 3 and the rotation peripheral speed of the handling cylinder 1 Teeth 12
Since the rotation peripheral speed of the distal end portion is set to be substantially the same, the transfer operation between them can be made extremely smooth. The sorted material that has fallen into the sorting room 20 is sorted by the wind sorting action by the compressed air Karino 22 and the swinging action by the swing sorting shelf 21, and is sorted into the first thing, the second thing, and the dust. They are separated and processed. During such an operation, when the dust in the handling chamber 2 reaches the dust outlet 7 at the terminal end, the dust on the guide rod 13 is carried around by the handling cylinder 1 as shown by the trajectory indicated by the dotted line in FIG. The one that moves and is sent to the processing chamber 4 and the one that falls onto the swinging sorting shelf 21 below from between the guide rods 13 are separated and separated. When falling, the dust is guided in the rotation direction of the handling cylinder 1 and discharged toward the center of the body. Dust in the processing chamber 4 is diffused while being carried by the diffusion wings 19 of the processing drum 3 while being sent from the handling chamber 2, and is discharged from the dust outlet 6 toward the center of the machine body. As described above, the sorted materials that have reached the sorting room 20 are sorted by the cooperative action of the swinging operation of the swinging sorting shelf 21 and the sorting wind by the pressurized air Karino 22.
