Next, the rice milling operation will be described with reference to FIG.
A user who has brought brown rice in a bag H first puts a charge into the charge insertion port 6, and then a cleaning process described later is performed, and then the lock member 36 of the lid 8 is unlocked. When the user opens the lid 8, puts brown rice brought into the insertion port 7 a of the insertion hopper 7, closes the lid 8, and the lid lock detection sensor 37 detects the lock of the lock member 36, the milling degree selection switch 7 selects It becomes possible. When the desired whiteness is selected and operated by the whiteness selection switch 7, each part of the machine room K and the wing room N starts to be driven, and is operated for an operation time corresponding to the charging fee.

  The brown rice in the charging hopper 7 is dropped and supplied from the opening 7 b of the charging hopper 7 to the upstream side 11 a of the rocking sorting plate 11 of the stone remover 10. Then, the metal mixed in the brown rice flowing upstream is removed by the magnet 21.

  In the swing sorting plate 11, the specific gravity of the brown rice and the stone mixed with the brown rice is selected, the stone moves upstream, and the brown rice flows down to the downstream side. In the middle of the flowing brown rice, the metals mixed in the flowing brown rice are removed by the magnet 22 provided across the left and right widths of the swing sorting plate 11 surface.

  The brown rice passes through the brown rice guide chute 13, passes through the introduction guide hopper 15, is cerealed by the elevator 14, and is stored in the brown rice tank 23 from the throwing port 14a. The brown rice in the brown rice tank 23 is sequentially supplied to the rice mill 25 by the rotary valve 24, discharged at the whitening degree set by adjusting the whitening pressure by the whitening degree adjusting mechanism 41, passes through the white rice guide chute 40, and is fed to the white rice hopper 28. Stored. Then, when the operation time elapses, the rice milling operation stops.

  If the rice sensor 7c detects the presence of brown rice when the rice milling operation is stopped due to a charge outage, a voice or a display device informs that an additional fee is necessary, and the rice milling operation is started again when the user adds a fee. Further, when the introduction sensor 7c detects the absence of brown rice during the rice milling operation, an end operation process is performed in which the stone remover 10, the elevator 14, and the rice mill 25 are stopped in the order of the processes. It is during this process that the stone extraction shutter 46 is opened and the stone is discharged from the stone discharge chute 16 to the stone storage box 19.

  When taking out the polished rice from the white rice hopper 28, the user hooks the bag H on the handle 30e, holds the handle 30e, and rotates the discharge shutter 30 downward. Then, the opening portion 28a is opened, and the polished rice is moved forward through the bottom plate portion 30a in an inclined posture and accommodated in the bag H from the discharge port 30h. The user visually recognizes the flow of polished rice through the transparent window 30d of the cover 30c. When the flow of polished rice is finished, the user removes the bag from the handle 30e and releases the handle 30e. Then, the discharge shutter 30 automatically returns to the initial position by the action of the spring 30g.

  Since the user can manually operate the discharge shutter 30 to receive the polished rice in a bag, the feet are stable and the polished rice can be taken out safely. Further, when the polished rice is discharged, the bottom plate portion 30a is forwardly lowered, so that the polished rice flowing down the bottom plate portion 30a is easily received by the bag.

Further, since the user can grip the handle 30e and rotate the discharge shutter 30 while hooking the grip portion of the bag H on the handle 30e, it is easy to operate and the polished rice is easily received by the bag H.
Further, by forming the wall portions 30b on the left and right sides of the bottom plate portion 30a, the polished rice can be concentrated and accommodated in the bag H without spilling from the left and right. Further, the polished rice is sequentially accommodated in the bag H, and the bag holder 31 can support the bag H being lowered by its own weight. Further, since the front end portion of the discharge shutter 30 protrudes forward from the surface position of the open / close door 2, the user can set the bag H and easily receive polished rice with the bag H.

  Further, since the polished rice flowing down the bottom plate portion 30a is discharged from the discharge port 30h to the bag H while being prevented from jumping at the cover portion 30c, the polished rice at the time of discharging is prevented from jumping and surely inside the bag H. Can be accommodated. Moreover, the state of the brown rice flowing down through the transparent window 30d can be visually confirmed.

  Furthermore, since the lower surface 29a of the extraction hood 29 is formed so as to be inclined downward, brown rice spilled on the lower surface 29a of the extraction hood 29 flows down by the inclined surface, so that it is prevented from remaining on the lower surface 29a. It can prevent the appearance at the time of non-milling rice from deteriorating.

Next, the above-described cleaning process will be described.
The cleaning process is a process of preventing the brown rice of the user before remaining slightly at the bottom of the charging hopper 7 from being mixed with the brown rice of the next user.

  Specifically, when a user inputs a charge, a vibration motor 7d that vibrates the input hopper 7 and a stone remover 10 are driven for a predetermined time (for example, 6 seconds), and the brown rice remaining in the input hopper 7 is normally polished. Unlike the time, in the case of a small amount, the swing sorting plate 11 does not flow down, but is transferred to the upstream side 11 a of the swing sorting plate 11. Then, the stone extraction shutter 46 is opened, the switching valve 18 is switched to the remaining rice discharge chute 17 side, and the residual brown rice is stored in the remaining rice storage box 20. When the predetermined time has elapsed, the driving of the apparatus for the cleaning process is stopped, the lock member 36 of the lid 8 of the charging hopper 7 is unlocked, and the user opens the lid 8 and inputs the brown rice.

Next, maintenance of the stone remover 10 will be described with reference to FIGS. 7 and 10.
When taking out the stone remover 10 to the outside of the box 1 for maintenance such as belt replacement, first, the removal hopper 7 can be removed by removing the support plate 42 that supports the loading hopper 7. Then, when the rear side of the stone punching machine 10 is lifted with a fulcrum shaft 43 formed at the lower part on the front side of the stone punching machine 10, the brown rice guide chute 13 is lifted and separated from the charging guide hopper 15. Further, the positioning hole 45 formed on the side of the stone removing machine 10 is removed from the positioning bolt 44 for positioning the stone removing machine 10. Then, the stone remover 10 can be pulled out to the front side.

  When the stone remover 10 is set to the initial position, when the rear side is lowered so that the positioning hole 45 is inserted into the positioning bolt 44 in a state where the rear side of the stone remover 10 is lifted, the brown rice guide chute 13 is inserted into the introduction guide hopper 15. Inserted into.

The stone remover 10 can be attached and detached with a simple configuration.
Next, the effect which arises from this Embodiment is demonstrated.
The stone punching machine 10 is arranged adjacent to the side wall 1a on the machine room K side in the box 1, the rice milling machine 25 is arranged in the center, the partition wall 32 is arranged adjacent to the rice milling machine 25, Due to the arrangement, the installation area is small, the noise of the rice milling machine 25 is difficult to leak out of the box 1, and the rice milling equipment of the present embodiment can be easily installed in an area with a large population. Moreover, since it arrange | positions in the left-right direction in order of the process of the stone remover 10, the rice milling machine 25, and the straw chamber N, it can make it easy to provide the elevator 14 and the straw conveyance cylinder 50.

  Further, since the rice milling operation does not start unless the lock of the lock member 36 of the lid 8 is detected by the lid lock detection sensor 37, the lid is opened after the rice milling operation, and foreign matter is put into the feeding hopper 7. This can be prevented. Moreover, since brown rice exceeding the capacity of the input hopper 7 cannot be polished at a time, the capacity of the white rice hopper 28 can be prevented from being exceeded.
