  The foreign matter sorting apparatus shown in Patent Document 1 transports normal soot leaked from the sorting hole by a screw conveyor horizontally mounted on the lower part of the sorting cylinder, and then lifts and discharges the normal soot and stores the normal soot in the tank part. On the other hand, the foreign material sorting apparatus shown in Patent Document 2 is configured to feed normal culm sorted by the sorting cylinder with a screw conveyor, then lift and discharge it and supply it to the feeder of the hulling machine. In any case, normal soot sorted by the sorting cylinder is transported by the screw conveyor located at the lower part of the sorting cylinder, and then further lifted and transported by the screw conveyor arranged on the terminal side of the foreign matter sorting apparatus. The structure is complicated, and the apparatus itself is also increased in size. For this reason, if the normal basket sorted out by the sorting cylinder is directly supplied to the hulling device, the screw conveyor can be omitted, the structure becomes simpler, and it is effective for downsizing and cost reduction of the device. In this way, it is extremely simple and reasonable to supply normal hulls from the sorting device to the hulling device or the like because the hulling device is simply disposed below the discharge hopper of the sorting device.

  However, when normal hulls leaked from the sorting device are continuously supplied to the hulling device in this way, if the processing capability of the hulling device is lower than the processing capability of the hulling device, wrinkles that cannot be completely processed by the hulling device. It collects in the discharge hopper of the sorting device. In this case, normal soot sorted out by the sorting cylinder overflows in the discharge hopper of the sorting apparatus and rubs against the sorting cylinder. In addition, there is a problem that it takes troublesome work to adjust the amount of soot into the sorting device while confirming the amount of soot in the discharge hopper, and the work efficiency is remarkably lowered.

  The present invention has been made in view of the above problems, and is a grain sorter capable of automatically adjusting the amount of straw supplied to the sorting device in accordance with the remaining amount of straw accumulated in the discharge hopper. The purpose is to provide.

And the shutter mechanism is held in an open state by the opening / closing driving means, and the opening / closing driving means is stopped without stopping the rotation driving means when the detection means detects a flaw. The shutter mechanism is lowered so as to block the supply path, and when the detection of wrinkles by the detecting means stops, the opening / closing driving means is driven to move to the initial position. .

  The present invention sorts grains and foreign matters with a sorting cylinder, in particular, puts straw into the sorter as grain, and sorts the straw sorted by the sorter in conjunction with the grain grinder to the grain grinder. By using a tube, rice straw-causing and normal rice cakes can be selected and only normal rice cake can be supplied to the hulling machine. Thereby, it is possible to prevent the rice straw-caused rice cake from being mixed into the normal rice cake supplied to the rice huller. In addition, when supplying normal hulls sorted by the sorter to the huller, hulls that cannot be hulled by the huller are accumulated in the discharge hopper, but when the wrinkle reaches a predetermined amount, the detecting means Can detect the soot in the discharge hopper, and can control the opening / closing drive means based on the detection signal from the detecting means to adjust the supply amount of soot into the sorting cylinder by the shutter mechanism. Sorting processing can be performed stably without overflowing soot in the hopper and coming into contact with the sorting cylinder and rubbing. This eliminates the troublesome task of frequently checking the amount of soot in the discharge hopper, and it is only necessary to put the soot in the supply hopper, resulting in excellent work efficiency.

  The shutter mechanism consists of a manual opening / closing shutter plate and an automatic opening / closing shutter plate driven by an opening / closing driving means. One manual opening / closing shutter plate is transferred to the sorting cylinder according to the processing amount of the hulling machine linked to the sorting machine. The amount of soot to be supplied can be adjusted in advance, clogging of the supply path can be suppressed, and an appropriate amount of soot can be supplied to the sorting cylinder, and the other automatic opening / closing shutter plate is a discharge hopper The amount of soot supplied into the sorting cylinder can be adjusted by automatically opening and closing the soot supply path by the opening and closing drive means based on the detection signal from the detecting means for detecting the soot inside.

It is a schematic explanatory drawing of the selection apparatus which shows one Example of this invention. It is a perspective view which shows the state linked with the hulling machine same as the above.

  The whole apparatus structure of the grain sorter in this invention is demonstrated using an accompanying drawing. Hereinafter, in the description of the overall configuration and examples of the present invention, the description is limited to the rice cake containing the rice straw causing disease as the grain to be selected, but it is widely applied to other cereals, agricultural products, and other granular materials. Of course, it is applicable.

  FIG. 1 is an explanatory diagram showing an outline of a sorting machine that is an embodiment of the sorting machine according to the present invention, and that realizes a sorting target as straw including rice straw. A sorting machine 1 according to an embodiment of the present invention includes a sorting cylinder 3 mounted horizontally in a housing 2, a motor 5 serving as a rotational driving means for rotating the sorting cylinder 3, and a sorting start position located on the sorting start end side. And a discharge hopper 7 located below the sorting cylinder 3 and a foreign matter discharge portion 15 located on the sorting end side.

  The sorting cylinder 3 is composed of a cylindrical mesh body 4 having a large number of slits 4a, 4a..., And normal soot M leaked and sorted from the slits 4a, 4a flows down to the discharge hopper 7. The foreign matter S such as rice straw-causing rice straw m, straw, and garbage that does not leak from the slits 4a, 4a is discharged from the foreign matter discharge portion 15. A motor 5 for driving the sorting cylinder 3 is fixed to the side surface of the housing 2, a switch 16 is provided at the lower part of the motor 5, and the supply hopper 6 is provided at the upper part of the motor 5. A lower portion of the supply hopper 6 is a supply path 8 communicating with the sorting cylinder 3, and the supply path 8 is configured to be opened and closed by a shutter mechanism 11 including two shutters 9 and 10. In FIG. 2, reference numeral 13 denotes a leg portion that supports the housing 2, and 14 denotes a power source for the motor 5, the solenoid 12, and the sensor 13. The switch 16 is an on / off switch for switching power supply or stop of the power supply 14 to the motor 5, solenoid 12, and sensor 13, and constitutes a closed circuit of the solenoid 12, sensor 13, power supply 14, and switch 16. .

  The two shutters 9 and 10 constituting the shutter mechanism 11 are assembled so as to be movable up and down by a guide mechanism (not shown) provided on the back side of the supply hopper 6 so as to overlap each other. One of them is a manual opening / closing shutter plate 9, and the other is an automatic opening / closing shutter plate 10 driven by a solenoid 12 as an opening / closing drive means. The automatic opening / closing shutter plate 10 is driven by the solenoid 12, and the solenoid 12 is controlled based on a detection signal from a sensor 13 which is a detection means for the bag M attached in the discharge hopper 7.

  As shown in FIG. 2, the sorter 1 configured as described above has the discharge hopper 7 disposed above the charging port (not shown) of the hulling machine 20, and the switch 16 is turned on to sort by the motor 5. While rotating the cylinder 3, the power of the power source 14 is supplied to the solenoid 12 and the sensor 13. In this way, the sorter 1 is activated and the soot M to be sorted is put into the supply hopper 6. At this time, it is possible to adjust the approximate amount of 籾 M supplied to the sorting cylinder 3 by moving the manually operated shutter 9 up and down. That is, if the manual opening / closing shutter plate 9 is lowered, the supply path 8 is narrowed, and the supply amount of soot M into the sorting cylinder 3 is reduced. If the manual opening / closing shutter plate 9 is raised, the supply amount of soot M into the sorting cylinder 3 is reduced. Will increase. In this way, by adjusting the supply amount of the soot M with the manual opening / closing shutter plate 9 in advance, clogging of the supply path 8 and the like can be suppressed, and an appropriate amount of soot M can be supplied to the sorting cylinder 3. Further, in the initial state, since the soot M sorted by the sorting cylinder 3 is not discharged into the discharge hopper 7, a signal for detecting the soot M is not output from the sensor 13, and the automatic opening / closing shutter plate 10 is initialized by the solenoid 12. Wait at the upper limit position.

  The soot M supplied into the sorting cylinder 3 from the supply path 8 of the supply hopper 6 is agitated by the rotation of the sorting cylinder 3, and the normal soot M that has been leaked and sorted out from the slits 4a, 4a of the sorting cylinder 3 is discharged. The rice straw disease that has flowed down to the hopper 7 and has not been leaked from the slits 4a, 4a is transferred to the terminal side of the sorting cylinder 3, and the rice grain disease that has flowed down from the terminal of the sorting cylinder 3籾 m and foreign matter S are discharged from the foreign matter discharge portion 15. Further, the normal basket M leaked and sorted from the slits 4 a, 4 a of the sorting cylinder 3 is continuously supplied from the discharge hopper 7 to the charging port of the hulling machine 20 and is subjected to a hulling process by the hulling machine 20. Here, if the supply amount of soot M from the sorter 1 is larger than the processing amount by the hulling machine 20, the soot M overflows from the charging port of the hulling machine 20 and accumulates in the discharge hopper 7. When a predetermined amount of soot M in the discharge hopper 7 accumulates, the sensor 13 detects the soot M. The solenoid 12 is driven by this detection signal, the automatic opening / closing shutter plate 10 is pushed down, and the automatic opening / closing shutter plate 10 narrows the supply path 8 or completely blocks it. As a result, the supply of soot M to the sorting cylinder 3 is restricted or stopped. On the other hand, the power of the power source 14 is supplied to the motor 5 and the motor 5 rotates without stopping, and the sorting process by the sorting cylinder 3 is continued. However, the supply of 籾 M is limited or stopped by the automatic opening / closing shutter plate 10. As a result, the amount of normal soot M to be sorted out from the sorting cylinder 3 is reduced. As a result, when the hull M in the discharge hopper 7 flows down due to the processing of the hulling machine 20, the hail M detection signal from the sensor 13 stops, and the solenoid 12 automatically lifts the automatic opening / closing shutter plate 10 up. The opening / closing shutter plate 10 is returned to the initial position (upper limit position). Thereafter, the same control is repeated, and the supply amount of the straw M to the sorting cylinder 3 is controlled by the automatic opening / closing shutter plate 10 in accordance with the processing amount of the huller 20, that is, the amount of the straw M accumulated in the discharge hopper 7. Control.

  As described above, in this embodiment, it is possible to control the supply amount of the soot M to the sorting cylinder 3 by the automatic opening / closing shutter plate 10 according to the amount of soot M accumulated in the discharge hopper 7. Thus, the sorting process can be performed stably without contacting and rubbing the sorting cylinder 3 that is rotating and overflowing with the soot M in the discharge hopper 7. Further, since there is no troublesome trouble of frequently checking the amount of soot M in the discharge hopper 7, it is only necessary to put the soot M into the supply hopper 6, so that the work efficiency is excellent. In addition, since the amount of hull M to be supplied to the sorting cylinder 3 can be adjusted in advance by the manual opening / closing shutter plate 9 according to the processing amount of the hulling machine 20 to be interlocked, the sorting process of the sorting cylinder 3 is further increased. Can be stabilized. In addition, the rice straw-causing mushroom m mixed in the rice bran M is enlarged by the rice koji mold, and is surely discharged from the foreign matter discharge section 15 without leaking from the slits 4a, 4a of the sorting cylinder 3, and the rice straw-causing rice cake m m is not supplied to the hulling machine 20 by being mixed with normal hail M.

  As mentioned above, although one Example of this invention was explained in full detail, this invention is not limited to the said one Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, an example in which the sorting machine 1 and the hulling machine 20 are linked is shown. However, the present invention is not limited to hulling and can be widely applied to various sorting applications. Further, the basic configuration of the sorter 1 and the opening / closing drive means of the automatic opening / closing shutter plate 10 are not limited to the solenoid 12 and may be appropriately selected such as a motor or various actuators.
