[0002]

2. Description of the Related Art A conventional threshing machine of this type, for example, sees the technology disclosed in Japanese Utility Model Publication No. 56-86959.
The handling chamber with the handling cylinder internally mounted and the processing chamber with the processing barrel internally mounted are arranged close to each other, so that the handling cylinder and the processing cylinder rotate in opposite directions. ing. Then, the grain removal in the handling room is sent to the processing room from the end portion of the handling room, while the processed material in the processing room is processed in the direction of the starting end of the handling room (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 room.

In this conventional structure, the movement of the processed material between the handling room and the processing room is limited to two places.

In recent years, combine harvesters are becoming larger in size (multi-row cutting) aiming at large-scale agriculture, and high-efficiency machines are required. Therefore, as a matter of course, the threshing device mounted on the combine needs to have a high threshing treatment capacity. In order to improve the threshing efficiency, the threshing device must have an organically related configuration between the handling room and the processing room, and must exhibit a highly efficient threshing processing effect by the synergistic action of both.

In the conventional threshing device, as has been seen in the above-mentioned prior art, the threshing processed product generally has one reciprocating motion between the handling chamber and the processing chamber. However, in this case, when a large amount of grain is generated in the handling room, it is sent to the processing room, and when the amount in the processing room is increased, it is returned to the handling room, etc., while balancing the processing amount between the two chambers and efficiently. There was a problem that could not be threshed.

Particularly, in the processing cylinder, when the handling chamber reaches an overloaded state and the rotation speed of the handling cylinder decreases, the rotation speed decreases in a synchronized state, and there is a problem that the processing capacity also decreases.

The present invention takes the following technical means in order to solve the above problems. That is, a handling chamber 2 in which a handling drum 1 for performing threshing treatment on grain culms is mounted on a shaft, and a treatment chamber 4 in which a processing barrel 3 for further threshing of the threshing treatment product is mounted in a processing chamber 4 are mutually connected. Communication that is arranged side by side close to the state where it can be fed and fed, and the rotations of the handling cylinder 1 and the processing cylinder 3 are opposite to each other so that the processing object can repeat the cyclic movement while drawing a figure 8 between the two chambers. It is a threshing processing device in a threshing machine configured to provide a mouth 5 and increase the processing capacity of the processing drum 3 when the inside of the handling chamber 2 is overloaded.

Next, the operation of the embodiment of the present invention will be described. First, an appropriate prime mover is started to drive the rotational power of the machine body to start threshing work. In this case, the processing cylinder 3
Are driven by the control motor 22, and the handling cylinder 1 and the processing cylinder 3 are rotating in opposite directions to each other as indicated by the arrow in FIG. Then, the grain culms are sandwiched by the feed chain 16 and conveyed while being fed from the grain culm supply port 6 to the handling chamber 2 and threshed by the rotating handling barrel 1. In this manner, the grain culms to be threshed are further subjected to the threshing action while being carried around by the handling teeth 11 of the rotating barrel 1. In the threshing-processed product, grains, dust, and the like leak through the sorting net 9 and reach the lower swing sorting shelf 27, while the branches attached particles are sent to the processing chamber 4.

At this time, the threshing material is bounced by the handling teeth 11 of the handling body 1 and sent to the processing chamber 4 through the communication port 5 while drawing the locus shown by the arrow in FIG. 3. At this time, Since the handling cylinder 1 and the processing cylinder 3 rotate in opposite directions to each other,
It passes through the lower side of the handling cylinder 1 and reaches the upper side of the processing cylinder 3,
It is inherited by the scraping blade 19 and is scraped into the processing chamber 4.
Then, the processing object is processed by the processing teeth 20 while being carried around by the processing cylinder 3 in the processing chamber 4.

In the threshing process, grains separated from straw, branch shoots, etc. in the threshing process leak to the lower sorting chamber 25 from the sorting nets 9 and 18 in both chambers. In the first half of the handling room 2, the unprocessed substances that are being continuously processed in the handling room 2 and the processing chamber 4 are inevitably increased in the amount sent to the processing chamber 4 because the threshing-treated products increase in the room, and the latter half of the latter. Then, the amount returned from the processing chamber 4 to the handling chamber 2 increases.

As described above, the threshing-treated product is processed while passing through the communication port 5 between the handling chamber 2 and the processing chamber 4 and inheriting each other. The processed material at the end portion is the reduction blade 2 at the end portion of the processing cylinder 3.
1 is repelled and is returned from the communication port 5 toward the starting end of the handling chamber 2. Therefore, the processed material is hardly clogged in the end portion of the processing chamber 4, and is appropriately circulated and processed.

Then, the sorted matter which has fallen into the sorting chamber 25 is sorted by the wind selecting action by the compressed air Kara 28 and the swinging action by the swing sorting shelf 27, and is sorted into the first product, the second product, and the dust. It is sorted and processed. During such threshing and sorting operations, the rotation sensor 14 is operated by the handling cylinder 1.
The number of rotations is detected through the handling barrel shaft 13 and the detected data is input to the controller 15. Then, the controller 15 outputs based on the detected data to drive the control motor 22.

Now, for example, in the handling room 2, a large amount of grain culm is sent at once, or a damp grain culm (when it is wet with rain dew).
Is sent, it becomes overloaded and the handling cylinder 1 inevitably
The number of rotations of will decrease. Next, when the rotation sensor 14 detects the number of rotations of the handling cylinder 1 from the handling barrel shaft 13 and inputs data, the controller 15 compares it with the reference data recorded. Calculation is performed, and if it is lower than the reference value, an output signal for acceleration is output.

When the speed-up signal is output in this manner, the control motor 22 is speeded up and driven at a high speed, so that the processing cylinder 3 is speeded up and the processing capacity in the processing chamber 4 is increased. . In this case, the processing cylinder 3 is speeded up in inverse proportion to the decrease in the rotation speed of the handling cylinder 1, and the processing capacity is significantly increased. The threshed material in the handling room 2 is supplied to the processing room 4 through the communication port 5 and processed by the processing body 3 which is rotated at high speed. In the threshing device in this embodiment, the processing capacity of the processing chamber 4 increases as the processing capacity of the handling chamber 2 decreases, and the threshing work can be performed while maintaining a high processing capacity as a whole.

[0026]

As described above, according to the present invention, the handling chamber 2 in which the threshing barrel 1 for threshing the grain culms is mounted, and the treatment barrel 3 for further threshing the threshed material are mounted in the rack. The processing chamber 4 and the processing chamber 4 are arranged side by side so as to be able to feed and feed the processing objects inside, and the rotations of the handling cylinder 1 and the processing cylinder 3 are opposite to each other. Is provided with a communication port 5 capable of repeating cyclic movement while drawing a figure 8, and when the handling cylinder 3 is overloaded, the processing capacity of the processing cylinder 3 can be increased. When the handling room reaches an overload condition and the number of rotations of the handling cylinder decreases, the control motor is accelerated and driven by the signal output from the controller based on the detected data. , Will be faster.
Therefore, the processed product in the handling room is characterized in that it is sent into the processing room and is immediately subjected to the processing action, and the processing capacity of the threshing apparatus as a whole is significantly increased.
