Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the grains deweighed in a hulling device are sorted into paddy, mixed rice, and finished rice in a swing sorting device, and this paddy is returned to the hulling device again. In addition, the mixed rice is shaken so that it can be rotated around the shaking sorting device.

This relates to an oscillating sorting huller that is configured to switch the mixed rice sorted by the oscillating sorting device to the hulling device and the oscillating sorting device. . Conventionally, in an oscillating sorting and hulling machine, the paddy that has been sorted by the oscillating sorting device is returned to the husking device, where it is weighed again, and then sent to the oscillating sorting device for further sorting.
The sorted mixed rice (a mixture of paddy and finished rice) is sent to a grain lifting device, and then sent to a swing sorting device where it is sorted again.

Also, the sorted finished rice is taken out of the machine. By the end of this work process, when the hulling and sorting work is about to end, the number of new paddy grains to be hulled decreases. Just before the end of the process, the amount of mixed rice supplied to the oscillating sorting device decreases, and sorting becomes impossible. Therefore, in the past, the mixed rice from the oscillating sorting device was taken out into a container 15 or the like outside the machine, and an operator supplied this to the rice funnel. Therefore, the work was troublesome and inefficient. The present invention was devised in view of the above-mentioned conventional problems.During the normal sorting operation by the oscillating sorting device, the mixed rice from the oscillating sorting device is returned to the oscillating sorting device, and the rice is returned to the oscillating sorting device just before the end. In this system, the mixed rice from the oscillating sorting device is switched to be fed to the paddy funnel, and the paddy in the mixed rice is also weighed.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to the drawings. In the figure, 1 is a rice hulling device, which is constructed as follows.

That is, 3 and 3 are deweighing rolls that rotate relative to each other, and the paddy supplied to the paddy funnel 5 provided above is transferred to the deweighing rolls 3 and 3.
It passes between the two, is pressed 10, and is deweighed. 7
11 is an opening provided at the lower part of the slope of the inclined plates 9, 9 provided below the scale removal rolls 3, 3, and 11 is a selection air passage provided below the inclined plates 9, 9. The generated sorting wind passes through.

15 communicates with the grain frying device 17 through a first spiral provided in the sorting air passage 11 at a position directly below the opening T of the opening 15.

19 is a second spiral provided on the leeward side of the first spiral 15 in the selective air passage 11 and communicates with the outside of the machine) 7-.

Reference numeral 21 denotes a swinging sorting device, which is constructed as follows.

That is, 23, 23, . . . are inclined sorting plates, which are supported on a support stand 25 via a swinging device 27. 29 is a storage tank that receives the grains transported by the grain lifting device 17, and supplies the grains from the bottom outlet 31 to the supply gutter 33.
, and is supplied to the inclined upper end portions of the sorting plates 23, 23, .

Numerals 35, 37, and 39 are a paddy extracting section, a mixed rice discharging section, and a finished rice discharging section provided at the inclined lower edge of the sorting plates 23, 23, . Mixed rice outlet 43
, a finished rice outlet 45 is provided.

As usual, a plurality of partition plates are attached to the inclined lower edge so as to be able to adjust their positions. The paddy outlet 41 is provided so as to look into the paddy funnel 5. 47 is a cover that covers the paddy outlet 41.

49 is a rack provided below the finished rice take-out part 39;
The surface is provided with an inclined protrusion, and the finished rice is transferred in the direction of the finished rice outlet 45 by swinging motion.

51 is a switching valve that switches the mixed rice take-out section 37 to the mixed rice take-out port 43 and the paddy take-out port 41 for communication; 53 is a handle that is integrally fixed to a shaft 55 that fixes and rotates the switch valve 51; , 57 are bullets for holding the handle 53 at the operating limit position.

Reference numeral 59 is a mixed rice breaking gutter that guides the mixed rice discharged from the mixed rice outlet 43 to the No. 1 spiral 15. In the above configuration, when carrying out hulling and sorting work, the switching valve 5 is
1 as shown in the solid line in FIG.
When paddy is supplied to the paddy, it falls between the demixing rolls 3 and 3,
Pressed and demixed.

Mixed rice, which is a mixture of deweighed finished rice and undemixed paddy, falls from the opening 7 into the sorting air passage 11, and the sorting air removes straw waste and dust from the machine by the air suction machine 13. The rice husks, impurities, etc. are discharged to the outside of the machine by the second spiral 19. The mixed rice is sent to the grain frying device 17 by the No. 1 spiral 15 and enters the storage tanker 29. The mixed rice in the storage tank 29 is discharged from the discharge port 31. Sorting plates 23, 2 via supply gutter 33
3,... is supplied to the inclined upper end of the sorting plates 23, 23,
...As it flows down, it is shaken and sorted, and the paddy is passed from the paddy removal section 35 to the paddy funnel 5 via the paddy removal port 41, and the mixed rice is transferred from the mixed rice removal section 37 to the mixed rice removal section 37. Exit 43
, the mixed rice is ring-formed into the first spiral 15 through the gutter 59.
Further, the finished rice is taken out of the machine from the finished rice take-out section 39 through the finished rice take-out port 45. As mentioned above, the mixed rice is repeatedly sorted, and the paddy mixed in this mixed rice is sorted and deweighed.This process is repeated, and the paddy is gradually demixed and sorted to become finished rice. and removed from the aircraft. To finish the work, rotate the switching valve 51 in the direction of arrow A in Fig. 3 to position it in the position indicated by the imaginary line, and the sorted mixed rice will be transferred to the mixed rice take-out section. 37, through the hull removal section 35, and the hull extraction port 41, and are then rounded into the hull funnel 3, where they are removed by the hull removal rolls 3, 3. Therefore, the paddy mixed in the mixed rice can be quickly and repeatedly weighed out, and the paddy mixed in the mixed rice can be weighed out repeatedly.
It can then be taken out as finished rice. Therefore, by simply switching the switching valve 51 as described above, it is possible to easily eliminate the residual rice that remains unsorted by the swing sorting device. As can be understood from the above description of the embodiments, the gist of the present invention is the configuration as described in the claims. The mixed rice from the dynamic sorting device can be fed to the paddy funnel without being taken out of the machine.

Therefore, just before the end of the process, the paddy in the mixed rice from the oscillating sorting device can be automatically weighed and taken out as finished rice, so that the remaining rice that remains without being sorted by the oscillating sorting device can be removed. It is possible to eliminate this and improve work efficiency. Note that the above-described embodiment merely shows one preferred embodiment, and various changes and modifications can be made to this embodiment without departing from the principles of the present invention.
