Dochien 15 is provided. The handle cylinder 1 has handle teeth 16 arranged on the outer circumference thereof and is rotatably mounted on the handle chamber 2 in a rotatable manner. Reference numeral 17 indicates a processing chamber, and 18 indicates a selection network.

Next, the sorting chamber 4 is provided below the handling chamber 2 and the swing sorting shelf device 3 is swingably suspended so that the grain removed from the handling chamber 2 can be swing sorted. It is configured. The compressed-air Karato 5 is composed of two machines, a first Kara5a and a second Kara5b, located at a lower position of the sorting chamber 4 below the swing sorting apparatus 3 and on the starting end side of the sorting chamber 4. .

In the lower part of the sorting chamber 4, the first transfer spiral 6 and the second transfer spiral 7 are provided in this order from the side closer to the compressed air sardines 5. The first transfer spiral 6 is configured to collect the first selected grains after threshing and carry them out of the machine. Next, the No. 2 transfer spiral 7 is configured to collect the No. 2 objects dropped in the sorting chamber 4 and convey them to one side, and the No. 2 lifting grain device 9 is provided at the end portion thereof. The second fried grain device 9 is composed of a fried grain spiral, and has a starting end portion connected to the end portion of the second transfer spiral 7 and an end portion opened to the upper second processing chamber 8 for communication.

The second processing chamber 8 is provided behind the starting end side of the handling chamber 2 (on the side opposite to the handling port 14), and the second processing drum 11 is mounted on the second processing chamber 8 to be supplied from the second lifting grain device 9. It is configured so that the second object can be processed and supplied to the lower swing selecting device 3. The second processing cylinder 11 is equipped with a rotation sensor 19 at the shaft end, measures the rotation speed, and sends it to the controller device 20 as a signal.

The measuring device 10 is installed in the second processing chamber 8,
The circuit configuration is such that the amount of the second processed material supplied can be measured and transmitted to the controller device 20. In the second processing cylinder 11, the speed changing belt 25 is wound around the speed changing pulley 24 of the second processing cylinder shaft 23 of the processing cylinder 1 and the speed changing belt 25 is used to change the speed change belt 26. The tension pulley 27 is operated by the gear shift operation.

The shift motor 26 is configured to be driven or stopped based on the output signal from the controller device 20. Therefore, the second processing cylinder 11
The supply amount of the second processed material in the second processing chamber 8 is measured by the measuring device 10 and transmitted to the controller device 20, while
When the rotation sensor 19 transmits the rotation speed of the second processing cylinder 11 to the controller device 20 and the filling amount (or the filling rate of the second processing object) in the second processing chamber 8 is smaller than the reference value, The rotation speed is decelerated to a predetermined value so that the filling amount can be increased.

Another Embodiment In the embodiment shown in FIG. 4, the second processing spiral 28 is attached to the end portion of the second lifting grain device 9. That is, the second processing spiral 28 is composed of a pair of an upper processing spiral 28a and a lower processing spiral 28b, and is provided on both the upper and lower sides with a gap 29 at the end of the second lifting grain device 9. Then, the treatment plate 30 is attached to the fixed outer cylinder, and the treatment spiral 2 is present in the gap 29 and seen from the axial direction of the fried helix.
It is configured so as to rush into the rotation range of 8a, 28b.

Reference numeral 31 indicates a blade for jumping out. Next, the operation will be described. First, while driving the rotating parts of the machine body, the grain culm is supplied to the starting end portion of the feed chain 15 and the tip portion is sent to the handling chamber 2. Then, the culm is
In the process of being held by the feed chain 15 and reaching the grain culvert discharge port 13 from the grain culm supply port 12 through the handling port 14,
Threshing processing is performed by the rotating barrel 1. And
In the grain removal, the unprocessed material is sent to the processing chamber 17 to be reprocessed, and drops into the sorting chamber 4 through the sorting net 18 and the dust outlet (not shown).

The objects to be sorted thus reached the sorting chamber 4 reach the swinging sorting device 3 and are sorted while being swung, and fall down to reach the sorting wind. . In the compressed air Kara5, the wind generated by the first Kara5a blows through the central portion of the rocking sorting device 3, and the wind of the second Kara5 blows above the first transfer spiral 6 and the second transfer spiral 7. The objects to be sorted that have reached the wind path are selected.

As described above, the objects to be sorted are sorted and separated by the swinging action of the swing sorting device 3 and the sorting wind by the compressed air Karako 5, and the ones most flow into the first transfer spiral 6. The second material flows into the second transfer spiral 7 and is conveyed to one side of the machine body. Then, the first product is carried out of the machine and stored by an appropriate fried device, and the second product is supplied to the starting end of the second fried device 9 and starts to be conveyed upward.

In this way, the second grain is supplied from the end portion of the second grain raising device 9 to the second treatment chamber 8 and, after the second grain is continuously shredded by the second treatment cylinder 11, the lower grain is processed. It falls on the swing sorting device 3. Now, in the second processing chamber 8 where the second processing operation continues, the supplied second material is measured by the measuring device 10, and the data is transmitted to the controller device 20. The second processing cylinder 11 is
The rotation speed is detected by the rotation sensor 19 and the data is transmitted to the controller device 20.

In the second processing cylinder 11, the amount of the second material supplied to the second processing chamber 8 in the data transmitted to the controller device 20 as described above is smaller than the reference value. In this case, an output signal for rotating the tension pulley 27 so as to operate the tension pulley 27 at a low speed side is issued from the controller device 20 to the speed change motor 26. Therefore, the second processing cylinder 11 receives the output signal as described above when the second material in the processing chamber 8 does not reach the reference amount, and the speed change motor 26, the tension pulley 27, the speed change belt 25, The speed is changed to a low speed through the speed change pulley 24, and the efficiency of the second processing action is reduced. Therefore, the second material in the second processing chamber 8 is sequentially accumulated and increased in amount, and the filling rate is increased.

In this way, the second processing cylinder 11 rotates at a low speed until the filling rate of the second material in the second processing chamber 8 reaches the reference value, and when the measurement result of the measuring device 10 reaches the reference value. ,
An output signal is issued from the controller device 20 to the shift motor 26. Then, the second processing cylinder 11 shifts to the shift motor 2
6, tension pulley 27, speed change belt 25, speed change pulley
The gear is shifted at a high speed through the lever 24, and the normal second processing operation is performed.

That is, since the second processing cylinder 11 is rotated at a high speed in accordance with the increase in the filling amount of the second material in the second processing chamber 8, the processing accuracy is improved and the processing is performed with branching. It is less discharged to the chamber 4.

[0021]

As described above, according to the present invention, the sorting chamber 4 equipped with the swing sorting device 3 is provided below the handling chamber 2 in which the handling barrel 1 is internally mounted, and the shaking of the sorting chamber 4 is performed. Dynamic sorting device 3
Is installed in order from one side to the compressed wind Kara 5, the first transfer spiral 6, and the second transfer spiral 7, and the upper end of the second transfer spiral 7 is opened to the second processing chamber 8. The lower part of the second fried grain device 9 is provided so as to communicate with each other, and the second processing chamber 8 is provided with a measuring device 10 for measuring the amount of the second product supplied, and based on the measurement result of the measuring device 10. Since the configuration is such that the rotation speed of the second processing cylinder 11 can be adjusted, the second processing operation can always be performed accurately.

That is, according to the structure of the present invention, as described above, the filling amount of the second processed material in the second processing chamber is always kept at a predetermined amount, so that the second processing operation is stable and the unevenness is small. However, it has a feature that it can always perform good shaving treatment.
