[0010]
By the way, the reduction passage 24 is for returning the grain conveyed to the machine room B side by the straw elevating machine 3 to the grain return port 26 on the operation room A side before entering the hulling machine 4 as described above. It is a passage. The flow path switching valve 28 provided adjacent to the upper part of the straw elevator 3 switches the grain conveyed by the straw elevator 3 between the side of the huller 4 and the reduction passage 24 side. The grain return port 26 is arranged above the supply tank 1, and the grain return button 27 when returning the grain is located away from the operation panel 25 in the operation room A and the grain return port 26. A nearby position, for example, as shown in FIG.
[0011]
The grain return port 26 is provided with a shutter mechanism interlocked with the supply spiral 2 and the straw elevator 3 as shown in FIG. That is, when the grain return button 27 is turned on, the supply spiral 2 and the straw elevator 3 are operated, and at the same time, the shutter 30 is opened by the operation of the solenoid 29 and the returned grain is conveyed to the grain return port 26. . When the grain return button 27 is turned off, the operations of the supply spiral 2 and the straw elevator 3 are stopped, and at the same time, the shutter 30 is closed by the operation of the solenoid 29, so that the grains moving through the reduction passage 24 are shut. It stops at 30 and does not spill from the return port 26. In addition, you may comprise so that returned grain may be conveyed as it is to the grain return port 26, without providing this shutter mechanism in particular.
[0012]
Here, the configuration of the flow path switching valve 28 will be described.
FIG. 10 is a partially cutaway front view showing the configuration of the flow path switching valve, and FIG. 11 is a side view thereof.
The flow path switching valve 28 can branch the grain conveyance path in two directions. In the present embodiment, as shown in FIG. Switching between two directions is possible. That is, a rectangular valve plate 31 is attached to the upper side of the shutter shaft 33 by screws 35 in a substantially symmetrical manner, and one end of the shutter shaft 33 is rotatably supported above the branch point of the flow path. The end is connected to the drive shaft of the motor 34.
[0013]
By driving the motor 34, the valve plate 31 rotates left and right with the shutter shaft 33 as a fulcrum, and the inclination angle of the valve plate 31 at the time of rotation can be stopped at an arbitrary position by a limit switch (not shown). However, downward triangular guide plates 32, 32 are respectively attached to the side wall surfaces of the shutter shaft 33 above the valve plate 31, and the thickness of the guide plate 32 is the valve plate 31. Since the valve plate 31 rotates to the left and right and abuts against the hypotenuse of the guide plate 32, the rotation is restricted to prevent overrun.
[0014]
Further, a certain amount of gap is provided between the lower end of the guide plate 32 and the shutter shaft 33 (see FIG. 10B) to prevent clogging of the grains at this portion. Further, as shown in the partially enlarged view of FIG. 11, the upper end of the guide plate 32 prevents a residual grain by making a downward cut.
[0015]
In such an arrangement, rice cake (and brown rice) introduced into the supply tank 1 is transferred to the rice cake elevator 3 by the supply spiral 2, and further conveyed upward by the rice cake elevator 3 and introduced into the rice huller 4. The The unpolished rice selected by the hulling machine 4 enters the stone removing machine 13, and the stone is selected by the stone removing machine 13. Next, the foreign matter removing device 5 is entered, where foreign matters such as sawdust are removed and sent to the rice lifting machine 6. The brown rice transported upward by the rice mill lift 6 is put into the rice mill 7. The polished white rice is stored in the white rice tank 8. The rice bran fed from the rice mill 7 is separated from the air by the cyclone 20, transported by the nutracene 21, and stored in the rice bag 23A, 23B.
[0016]
By the way, when the rice milling operation is stopped on the way for some reason, for example, when the fee is insufficient and the rice bran or brown rice left in the supply tank 1 remains, the grain return button 27 is used to take them home. Press. When the grain return button 27 is pressed, the valve plate 31 of the flow path switching valve 28 rotates, and the flow path is switched from the hulling machine 4 side to the reduction passage 24 side. The grain remaining in the supply tank 1 is returned to the grain return port 26 from the transport path through the reduction passage 24 by the operations of the supply spiral 2 and the straw elevator 3. Thereby, not only the supply tank 1 but also the grains remaining in the transport path can be recovered. In addition, since the grain return port 26 is disposed above the supply tank 1, the return port is located at a relatively high position and the workability is good, and the returned grain is not received by a bag or the like. Even in this case, since the returned grains enter the supply tank 1 again, scattering on the floor of the operation room A can be prevented.
[0017]
Further, since the grain return button 27 is provided at a position away from the operation panel 25 in the operation room A and in the vicinity of the grain return port 26, the grain return button 27 is mistakenly set during the rice milling operation. It is possible to prevent an erroneous operation of pushing.
[0018]
Further, the above-described flow path switching valve 28 has a very simple structure composed of a rotatable valve plate 31 and a triangular guide plate 32 that regulates the rotation thereof, and therefore does not require bending and is inexpensive. Assembly is also easy. As described above, a certain amount of gap is provided between the lower end of the guide plate 32 and the shutter shaft 33 to prevent clogging of the grains, and residual grains are formed by making a downward cut at the upper end of the guide plate 32. To prevent. Further, by adjusting the valve plate 31 with the screw 35, it becomes easy to adjust the position after processing.
[0019]
The return operation is started by pressing the grain return button 27 only once, and is returned until all the grains remaining in the supply tank 1 are exhausted unless the return operation is stopped by pressing the grain return button 27 again. By configuring so as to continue the operation and return the coins inserted after the return operation is completed, it is not necessary to keep pressing the grain return button 27, and it is only necessary to press the button once. In addition, you may comprise so that the return operation | movement of a grain may be continued only when the grain return button 27 is kept pressed.
[0020]
Moreover, as another embodiment of the present invention, by providing a reduction passage to the above-described grain return opening in the rice mill elevator 6, only rice hulling and stone removal may be performed and returned in the state of brown rice. .
[0021]
12 and 13 show another embodiment of the above-described flow path switching valve.
That is, as shown in FIG. 12, the projection 37a on the back surface of the triangular guide plate 37 is passed through the hole of the side wall 36, and the spring 38 is engaged with the projection 37a. Install to.
In such a configuration, as can be seen from the series of movements shown in FIGS. 13A to 13C, the guide plate 37 rotates in a state where it is always in contact with the valve plate 31 as the valve plate 31 rotates. The clogging of grains can be prevented by eliminating the gap between the valve plate 31 and the guide plate 37.
[0022]
14 and 15 show another embodiment of the flow path switching valve.
That is, as shown in FIG. 14, the projection 39a on the back surface of the triangular guide plate 39 is passed through the vertically long hole 36a of the side wall 36, and the spring 40 is engaged with the projection 39a. Install it up and down.
In such a configuration, as can be seen from the series of movements shown in FIG. 15, as the valve plate 31 rotates, the guide plate 39 moves up and down while always in contact with the valve plate 31. Grain clogging can be prevented by eliminating the gap with 39.
[0023]
16 and 17 show another embodiment of the flow path switching valve.
That is, as shown in FIG. 16, the protrusion 41a on the back surface of the triangular guide plate 41 is passed through the laterally long hole 36b of the side wall 36, and the leaf spring 42 is engaged therewith. As shown in FIG. 17, the guide plate 41 moves left and right with the valve plate 31 always in contact with the valve plate 31, as shown in FIG. 17, and the gap between the valve plate 31 and the guide plate 41. Can prevent grain clogging.
