  Based on the drawings, the coin rice milling machine partitions the inside of the rice milling building 15 into an operation room 2 and a machine room 3 by a partition wall 1. The operator can enter and leave the operation room 2, bring in rice or brown rice, and supply it to the input hopper 4 disposed on one side of the partition wall 1. In addition to the charging hopper 4, the partition wall 1 includes a coin mech 16 for inputting a fee for performing rice polishing, a whitening degree switch 17 for selecting the whiteness of rice polishing, other operation switches, a pilot lamp, and the like. An operation board 18 to be arranged is provided, a white rice hopper 19 for taking out the polished white rice is provided on the lateral side, and the white rice taken out from the white rice hopper 19 can be received and taken home. A bag mounting table 20 is provided in front of the charging hopper 4 to facilitate the supply of supplied rice (brown rice or brown rice) to the charging hopper 4.

  In the machine room 3, an elevator 6, a hulling machine 21 in the form of an impeller detachment, a hulling sorting device 22, a suction dust remover 9, and the like are arranged at the back side of the charging hopper 4. The dust removal cylinder 23 of the dust removal machine 9 is opened to the outside of the building 15. In addition, a sorting device 7 and a brown rice elevator 24 are disposed on the back side of the operation board 18, and a rice milling device 8 is disposed on the back side of the white rice hopper 19. Further, a cyclone-type dust collecting device 25 is provided on the back side of the sorting device 7 and the rice milling device 8.

  Here, the coin milling machine is a rice milling apparatus in which an intake port 12 for sucking and guiding outside air outside the machine room 3 is provided between the outlet 10 of the spiral mill 5 and the inlet 11 of the elevator 6. The configuration.

  The coin milling machine can automatically mill rice as white rice by supplying and supplying a predetermined amount of supplied rice and a rice milling fee for milling and milling it. Then, a predetermined amount of supplied rice is introduced into the introduction hopper 4 of the operation chamber 2 to perform rice milling and rice polishing. The supplied rice supplied to the charging hopper 4 is fed by driving the spiral of the spiral rod (auger) 5 at the bottom, and is fed from the outlet 10 of the spiral rod 5 to the inlet 11 of the elevator 6. 6 is transferred to the sorting device 7, the rice smashing sorting device, the rice milling device 8, etc., and the rice milling and rice milling operations are performed. Further, during such a rice milling action, the suction pressure of the sorting device 7 and the suction dust remover 9 that sucks and removes rice husks, milled rice bran, etc. is working in the machine room 3 and is in a negative pressure state. Therefore, the suction negative pressure acts on the intake port 12 between the spiral rod 5 and the elevator 6, sucks outside air from the intake port 12, and sucks negative pressure to the inside of the spiral rod 5. Thus, even if the spiral of the spiral rod 5 is stopped, the suction negative pressure can reduce or prevent the suction feed to the outlet side. For this reason, when the negative pressure due to the suction wind pressure is working in the machine room 3, the spiral drive of the spiral rice bran 5 is stopped, but the brown rice of the input hopper 4 and the supplied rice of the brown rice are transferred to the elevator 6 side. Is stopped.

  The intake port 12 forms an intake cylinder 13 for sucking and guiding the outside air outside the spiral cage 5 or communicates with the operation chamber 2 to suck and guide the outside air in the operation chamber 2. 13 is formed.

  The negative pressure acting in the machine chamber 3 as described above acts on the intake port 12 between the outlet 10 of the spiral rod 5 and the inlet 11 of the elevator 6, and causes the intake cylinder 13 formed in the intake port 12 to Then, the suction negative pressure working in the spiral rod 5 is reduced by communicating with the outside of the machine chamber 3 or the operation chamber 2. Even if there is supplied rice that jumps out to the intake port 12 due to the intake of outside air from the intake cylinder 13, it is easily sucked and conveyed to the elevator 6 and the inlet 11 side.

Further, the intake port 12 is provided with an on-off valve 14 that can be closed during the rice milling operation.
As described above, the suction negative pressure state is maintained in the machine chamber 3 by driving the suction dust remover 9 and the like, so that when the opening / closing valve 14 of the intake port 12 is open, the outside air is drawn from the intake port 12. When suction is performed to eliminate or reduce the suction negative pressure action on the side of the spiral basket 5 and stop the spiral drive in the spiral basket 5, the suction and conveyance of brown rice and the like from the spiral basket 5 is accurately prevented. For this reason, the on-off valve 14 generally closes the intake port 12 during the rice milling operation, and operates to open the intake port 12 when the rice milling operation is stopped, thereby stopping the feeding and conveying from the helical rice cake 5. Unnecessary suction conveyance due to the negative pressure in the machine chamber 3 is prevented.

  At the bottom of the charging hopper 4, a spiral rod 5 is provided facing the back side, and the back side outlet 10 is opened through the inlet 11 of the elevator 6. By driving and rotating the spiral 26 of the spiral rod 5 by the electric motor M1, the supplied rice in the charging hopper 4 is guided to the spiral rod 5 and conveyed to the outlet 10 and supplied to the inlet 11 of the elevator 6 by flowing down.

  The soot transported by the elevator 6 is transported and supplied to the hulling machine 21 by the switching valve 28 to perform the detaching action. The squeezed rice to be deflated flows down from the defluxing funnel 27 to the sorting air passage 28, and the crushed rice thus selected is supplied to the sorting device 7 via the chute 29. The brown rice sorted by the sorting device 7 is conveyed and supplied to the rice milling device 8 via the elevator 24. The hulling sorter 22 is provided with a suction dust remover 9 for flowing suction air to the sorting air passage 28, and the dust discharge cylinder 23 while sucking the air in the machine room 3 through the sorting air passage 28. Guidance to the wind. Further, in the impeller-shaped huller 21, the crushed rice is raised to the detaching funnel 27 while sucking from the inside of the machine room 3 by the rotation of the impeller.

  Further, when brown rice is fed to the feeding hopper 4 to the supply sorting device 7 side, the switching valve 29 is switched and supplied to the sorting device 7 from the elevator 6 via the chute 30 to perform the sorting action of the brown rice. The selected brown rice is supplied to the rice milling device 8 via the elevator 24.

  The rice milling device 8 also has a wind-selecting device for removing the debris, and the suction rice pressure is passed through the rice milling chamber to remove it while removing it to the dust collecting device 25. While sucking the sorting wind from the elevators 6 and 24, the hopper that receives the grains raised from the elevators 6 and 24, and the sorting dust discharge part of the rice hull sorting device, the rice husks from the suction sorting dust exhaust wind In addition, rice removal, dust removal and the like are collected in a cyclone and packed in a bag 31, and only dust is discharged from the dust discharge cylinder 23 to perform sanitary scouring and polishing.

  As described above, when all or a part of the rice hull sorting device 22 and the rice milling device 8 are in operation, the suction wind pressure generated by the rotation of the suction fan of the suction dust remover 9 and the sorting device 7 is reduced to the machine chamber 3. Working inside, this suction wind pressure (negative pressure) acts on the intake port 12 in the vicinity of the exit 10 part of the spiral rod 5, and the outside air outside the machine room 3 can be sucked from the intake port 12. In a state in which outside air can be sucked from the intake port 12, the negative pressure in the machine chamber 3 also acts on the outlet 10 of the spiral rod 5, so that the granules in the charging hopper 4 pass through the spiral rod 5. And I work to inhale brown rice. Therefore, if the intake port 12 is in an open state or the open / close valve 14 is provided and the open / close valve 14 is opened so that outside air is inhaled from the intake port 12, the intake port 12 is positioned near this position. Since the negative pressure which acts on the outlet 10 of the helical rice cake 5 to be formed is weakened, it becomes a state where the rice cake and the brown rice which are stagnant inside the helical rice cake 5 cannot be sucked out.

  As shown in FIG. 5, the intake port 12 is formed by forming an intake chamber 32 at a position slightly higher than the position of the outlet 10 of the spiral rod 5, and forming the outlet 12 in the intake chamber 32. An intake cylinder 13 is provided continuously. Although the outside air intake port of the intake cylinder 13 may be viewed outside the building 15, it is configured to be viewed inside the operation chamber 2. In particular, it is possible to make it difficult to suck dust by looking over the ceiling of the operation chamber 2.

  When the machine chamber 3 is in a negative pressure state, even if the outlet 10 of the spiral rice bran 5 is sucked in, the suction port 12 in the vicinity of this position sucks easily and sucks the brown rice in the spiral rice bran 5 because suction is easy. Is not carried out, and there is no swallowing / sucking / unloading from the rice bran 5 such as brown rice when the supply in the charging hopper 4 is stopped, so that the elevator 6, the rice huller 21, or the rice milling device 8 can be removed. It prevents clogging and defects.

  Next, in the form in which the opening / closing valve 14 is provided at the intake port 12 mainly based on FIG. 6, the opening / closing valve 14 is closed during the operation of the rice mill, and the rotation of the spiral 26 is temporarily stopped, or The on-off valve 14 is operated to be opened when the rotation of the spiral 26 stops just before the end of the operation. In the illustrated on-off valve 14, a spring 36 is provided around a hinge pin 35 for opening / closing rotation, and the on-off valve 14 is automatically opened and rotated by a negative pressure acting against the pressure of the spring 36. Thus, outside air can be sucked into the machine chamber 3 from the intake port 2, and the negative suction pressure with respect to the outlet 10 of the spiral rod 5 is weakened.

  FIG. 7 shows an open sensor 37 for detecting that the on-off valve 14 is opened more than a predetermined amount against the force of the spring 36, and is constituted by a limit switch. When it is detected by the open sensor 37 that the on-off valve 14 is opened, an alarm or the like is output to notify the operator that the inside of the machine room 3 is in a negative pressure state.

  Next, mainly based on FIG. 8, an opening / closing valve 14 that is opened / closed by an electromagnetic solenoid 37 is provided on the ceiling cover 34 of the inlet funnel 33 that covers the space between the outlet 10 of the spiral cage 5 and the inlet 11 of the elevator 6. . This on-off valve 14 activates a solenoid 37 when the operation of the coins supplied to the coin mech 16 is stopped due to the coins running out and when the brown rice sensor in the insertion hopper 4 detects that the brown rice has run out. The on-off valve 14 is opened so that outside air can be sucked from the intake port 12.

  Next, mainly based on FIG. 9, the elevator 6 is provided with an intake port 12 for sucking the outside air into the machine room 3. A mounting plate 38 having an intake port 12 and an opening / closing valve 14 for opening and closing the intake port 12 is attached to the upper opening 40 of the elevator 6 with screws 39 and the like, and the intake port 12 by the opening / closing valve 14 is opened. As a result, the outside air is sucked into the elevator 6 through the intake cylinder connected to the intake port 12 and the action of the negative suction pressure on the spiral rod 5 is weakened. This form is effective in the case where the helical rod 5 outlet 10 and the inlet 11 of the elevator 6 are connected in an airtight manner. It has the same object and effect as the embodiment in which the inlet 12 is provided at the inlet 11 of the elevator 6.

  Next, mainly based on FIG. 10, as described above, the shooter 30 and 44 for guiding to the rice huller 21 are provided in the cereal hopper 41 mouth portion 42 of the elevator 6, and these shooters 43 and 30 are provided. In the form of the switching valve 29 that switches between the two, the switching valve 29 can be switched so that it flows down to the shooters 30 and 44 side when interlocking and at the end of coins, and is taken out from the shooter 44. Workers can take home the harvested rice. When a small amount of supplied rice remains in the charging hopper 4 part due to the rotation of the pallet separating apparatus 22 part, this residual rice is easily sucked into the elevator 6 and is easily sucked and conveyed. However, by operating the switching valve 29 toward the take-out side, the connection between the hulling machine 21 and the charging hopper 4 can be cut off, and the sucking and conveying of the remaining rice can be prevented.

  The switching valve 29 of the cereal hopper 41 can be switched so that it flows down to the shooter 43 on the side of the rice grinder 21 and the shooter 30 on the sorting device 7 side. A valve 45 is provided and is configured in the form of a two-stage switching valve that switches between the sorting device 7 side and the shooter 44 on the operation chamber 2 side.
