Description

[Detailed explanation of the idea] The present invention relates to a device for removing rice left over from an oscillating grain sorter.

That is, in a swinging grain sorting machine configured to be able to sort and separate mixed rice by swinging a plurality of stacked grain sorting plates having rough surfaces in an inclined position, the sorted and separated brown rice, mixed rice, and It has a structure that allows each paddy to be guided well and discharged to the next process, and if paddy is mixed in the brown rice layer at the start of work, it is discharged to the mixed rice discharge gutter side for the next mixed rice processing process. In addition, the remaining rice can be easily discharged from the machine and disposed of, and the structure is simple and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a plan view of the oscillating grain sorting machine, in which four grain sorting plates 2 having rough surfaces 1 are stacked on top of each other so as to be inclined in the vertical direction Y and the lateral direction Each grain selection board 2 is supported by dynamic support rods 10, 10, and connected to the swing arm 13 with an eccentric wheel 12 driven by a motor 11 so as to be able to swing each grain selection plate 2 in the lateral direction X. The structure is similar to the conventional type in that the mixed rice can be supplied onto each grain selection board 2 from the supply tank 14 installed on the upper side of the slope in the vertical direction Y.

A discharge case 15 is installed facing the lower end of the Y-slanted vertical direction of each grain sorting board 2, and side partition plates 3 and 4 are installed vertically within the discharge case 15 at intervals in the horizontal direction. The front surface of the discharge case 15 has elongated holes 16 and 17 in the horizontal direction, and knobs 18 and 19 for tightening and fixing the side partition plates 3 and 4, respectively.
The side partition plates 3 and 4 are movably inserted into the long holes 16 and 17, and the side partition plates 3 and 4 are installed along the long holes 16 and 17 so as to be movable and adjustable in the lateral direction. A brown rice discharge gutter 5 is visible below between the partition plate 3 and the side of the discharge case 15, where the brown rice layer is visible, and the mixed rice layer is visible between the side partition plates 3 and 4. Below that, there is a mixed rice discharge gutter 6, and below between the partition plate 4 and the other side of the discharge case 15, where the paddy layer is exposed, there is a paddy discharge gutter 7. The valley gutters 7 and 6.5 are stacked vertically and extend laterally, with the gutters 7 going towards the hulling machine, the ditch 6 going back to the supply tank 14 side, and the ditch 5 going towards the rice sorting machine, respectively. It is constructed in the same way as the conventional type, with continuous connections so that paddy, mixed rice, and brown rice can be sent out.

A switching valve 8 is interposed between the upper part of the brown rice discharging gutter 5 and the end of the mixed rice discharging gutter 6, and the switching valve 8 is rotated by an outer lever 20 so that the middle of the brown rice discharging gutter 5 is moved. It is installed and configured so that it can be opened and closed and guided from the brown rice discharge gutter 5 side to the mixed rice discharge gutter 6 side.

Further, a residual rice discharge gutter 21 communicating with the outside of the machine is provided in the middle of the brown rice discharge gutter 5 below the switching valve 8, and the rain gutter 5
, 21 is equipped with a residual rice switching valve 9 which can be rotated by an external lever 22, and is installed so that one side of the rain gutters 5, 21 can be closed by the switching valve 9. Configure.

Therefore, during work, the switching valve 8 is raised to the side of the mixed rice discharge gutter 6 to open the brown rice discharge gutter 5, and the remaining rice selector valve 9 is moved to the side of the residual rice discharge gutter 21 to open the brown rice discharge gutter 5. When this is done, the mixed rice supplied from the supply tank 14 is sorted and separated by each grain selection plate 2, and the brown rice flowing out from the brown rice layer is guided by the partition plate 3 and passes through the brown rice discharge gutter 5 as it is. The mixed rice flowing to the rice sorting machine and flowing out from the mixed rice layer is guided by the partition plates 3 and 4, passes through the mixed rice discharge gutter 6, is returned to the grain sorting plate 2 as it is, and flows out from the paddy layer. The paddy is guided by the partition plate 4, passes through the paddy discharge gutter 7, and is directly returned to the huller, where the mixed rice is sorted and separated.

When starting work, etc., if paddy is mixed in the brown rice layer, by tilting the switching valve 8 toward the brown rice discharge gutter 5 side and closing it, the paddy can be guided by the switching valve 8 and flowed out to the mixed rice discharge gutter 6. Can be done.

In addition, when removing the remaining rice at the end of the work, the remaining rice switching valve 9 is raised to the side of the brown rice discharge gutter 5 and closed.
When the side is opened, the remaining rice can be taken out of the machine from the remaining rice discharge gutter 21.

As described above, the present invention provides a swinging grain sorting machine configured to be able to sort and separate mixed rice by swinging a plurality of stacked grain sorting plates having rough surfaces in an inclined position. A brown rice discharge gutter, a mixed rice discharge gutter, and a paddy discharge gutter, which are partitioned and guided by side partition plates, are installed outside the discharge side end of the plate, and the brown rice discharge gutter is separated and guided by a side partition plate, and the brown rice discharge gutter is separated and guided by a side partition plate. A switching valve that can switch from the discharge gutter side to the mixed rice discharge gutter side is installed, and a residual rice switching valve that can switch and guide the brown rice discharge gutter side to the leftover rice discharge gutter side is installed in the middle of the brown rice discharge gutter. Separated brown rice, mixed rice, and paddy can be efficiently guided and discharged through each gutter and sent to the next process, and if paddy is mixed in the brown rice layer at the start of work, the switching valve can be operated. The remaining rice can be guided to the mixed rice discharge gutter side for the next mixed rice processing process, and can be properly disposed of.When removing the remaining rice from the machine, the remaining rice can be removed from the rice discharge gutter by operating the residual rice switching valve. It has the advantage that it can be easily guided to the side and discharged outside the machine, and that it can be easily implemented with a simple structure.
