It is characterized by that.

  In the component type grain sorter according to claim 3 of the present invention, the supply unit includes a supply pipe communicating with each supply side of the sorting cylinder and the carry-out conveyor, and either one of the supply pipes is closed. A damper is provided that opens the other and switches the supply destination of the particles to be sorted to the sorting cylinder or the carry-out conveyor.

  According to a fourth aspect of the present invention, there is provided a method for removing foreign matter from a component type grain sorter, wherein the suction connection pipe for deaeration is connected to a dust collecting unit facing a dropping path connecting the inlet and the inlet of the feeder hopper of the feeder unit. The foreign matter mixed in the granular material supplied from the charging hopper is separated by the air flow generated by sucking outside air from the suction connection pipe, and the flow is reduced from the sorting unit to the chute. There is provided a suction pipe for sucking air in the discharge path of the grains and the discharge path of the waste grains from the carry-out conveyor to the discharge pipe of the carry-out conveyor, and the suction pipe and the suction connection pipe communicate with each other.

By switching the damper so as to close the cylinder-side supply pipe and open the carry-out conveyor-side supply pipe, it is possible to move to the basic base unit or the base unit carry-out conveyor without sorting the granules. And the carry-out conveyor can be used simply as a conveyor for transferring particles, and the versatility can be further improved.

  In addition, when particles such as brown rice are put into the input hopper for sorting, foreign matters mixed in the particles flowing down from the input hopper to the drop path are sucked by the air flow generated by the suction of air from the suction connection pipe. The foreign matter is separated from the granules supplied from the charging hopper to the sorting unit. Further, foreign substances are separated from the sized particles discharged from the sorting unit by the air flow generated by the suction of air from the suction tube and discharged to the discharge tube in the sized particle discharge path, and are sucked into the suction tube. Furthermore, foreign matter mixed in the waste particles discharged from the carry-out conveyor after passing through the sorting unit is separated by the air flow generated by the suction of air from the suction pipe and mixed into the waste particles discharged from the carry-out conveyor. The foreign matter separated is separated in the waste particle discharge path and sucked into the suction pipe. This makes it possible to effectively remove foreign matters such as slag mixed with the sized particles sorted by the sorting unit and the waste particles discharged by the carry-out conveyor when the granules are supplied from the charging hopper. it can.

  Next, a specific structure of the basic component will be described with reference to FIGS. 2 shows the basic base unit 7, and FIGS. 3 and 4 show the base unit 8. Here, the basic base unit 7 and the base unit 8 are different in that the number of sorting units 2 is different, and the substantial structure is common. Therefore, only the base unit 8 will be mainly described, and the basic base unit 7 will be described. Detailed description is omitted.

  The sorting unit 2 is composed of a cylindrical sorting cylinder 10 composed of a mesh casing made of a required mesh as a whole, and a drive motor 11 for rotating the sorting cylinder 10, and the supply side of the granules is at a high level. It is installed on the base 6 so as to be inclined at a required angle so that the discharge side of the granules becomes the bottom position. The sorting cylinder 10 has a mesh size (mesh width) determined according to the quality, grade or application of the rice grains to be sorted, and scrap particles below the standard passing through the mesh flow down to the carry-out conveyor 4. It is unloaded from the unloading conveyor 4. On the other hand, the sized particles conveyed to the lower discharge side without passing through the mesh of the sorting cylinder 10 fall from the sorting cylinder 10 to the chute 5 and are carried out of the machine. The base unit 8 is rotatably supported by the base 6 so that the upper and lower two-stage sorting cylinders 10 and 10 are parallel to each other.

  The supply unit 3 of the base unit 8 is located on the supply end side 10a (higher side) of the sorting cylinders 10 and 10 and is assembled to the base 6. From the input hopper 12 for granules, The supply pipes 13 and 13 are divided into two forks. As shown in FIG. 5, the end of one supply pipe 13 faces the supply-side opening of the sorting cylinder 10 located on the upper side, and the lower sorting cylinder 10 faces the end of the other supply pipe 13. A flexible pipe 14 extending to the supply side opening is connected. Further, a hopper 17 for receiving the granules supplied from the flexible pipe 14 is provided on the side of the lower sorting cylinder 10, and the granules supplied to the charging hopper 12 are vertically moved from the supply pipes 13 and 13. Supplied into each sorting cylinder 10, 10.

  As shown in FIG. 2, the supply unit 3 of the basic base unit 7 includes a granule charging hopper 12, a sorting cylinder supply pipe 18 that feeds granules from the charging hopper 12 to the sorting cylinder 10, An unloading conveyor supply pipe 19 is provided below the sorting cylinder supply pipe 18 and supplies the particles from the input hopper 12 to the unloading conveyor 4. A damper 16 is rotatably supported in the charging hopper 12, and the damper 16 is rotated by an operation lever (not shown) provided on the outer surface of the charging hopper 12, so that a supply pipe for a sorting cylinder is provided. 18 and the supply pipe 19 for the carry-out conveyor are closed and the other is opened, thereby switching the supply destination of the granular material to either the sorting cylinder 10 or the carry-out conveyor 4. In the solid line in FIG. In this state, the sorting tube supply pipe 18 is closed and the carry-out conveyor supply pipe 19 is opened. In this state, the granules put into the loading hopper 12 are discharged from the carry-out conveyor supply pipe 19. It is supplied to the carry-out conveyor 4.

  As shown in FIG. 3, in the lower part of the lower-stage sorting cylinder 10, inverted trapezoidal waste grains that receive waste grains that have passed through the meshes of the sorting cylinders 10, 10 along the longitudinal direction of the sorting cylinder 10. A collection hopper 20 is disposed, and a sized particle collection hopper 35 is disposed adjacent to the waste particle collection hopper 20 at a position facing the discharge end side 10b (lower side) of the lower sorting cylinder 10. . A connecting frame 21 that guides the waste particles from the waste particle collection hopper 20 to the carry-out conveyor 4 is fixed to the lower portion of the waste particle collection hopper 20.

  As shown in FIGS. 4 and 6, the connecting frame 21 is bent so that the position of the carry-out conveyor 4 is distributed either forward or backward (in a direction orthogonal to the axial direction of the carry-out conveyor 4). The carry-out conveyor 4 is disposed at either the front side or the rear side that is displaced from the center of the base unit 8 in accordance with the direction in which the waste particles are conveyed by the conveyor 4. That is, as shown in FIG. 4, the sized particle collection hopper 35 and the sized particle discharge chute 5 connected to the sized particle collection hopper 35 are arranged at the center of the base unit 8, and the sized particle collection hopper 35 is arranged. It is necessary to arrange the carry-out conveyor 4 at a position that avoids the grain collection hopper 35 and the chute 5, and it is necessary to distribute the position of the carry-out conveyor 4 in the front-rear direction by a method for selecting the granules to be described later. Further, the unloading conveyor 4 arranged at the lower part of the connecting frame 21 is also connected to the connecting frame 21 so that the conveying direction of waste particles can be transferred to either the right side or the left side in FIG. The carry-out conveyor 4 can be slidably mounted, and the guide structure of the carry-out conveyor 4 will be described with reference to FIG.

  As shown in FIG. 4, the unloading conveyor 4 is connected to a transfer cylinder 23 in which a screw 22 for transferring waste particles is rotatably arranged, a drive motor 24 that rotationally drives the screw 22, and the transfer cylinder 23. The exhaust pipe 25 is made up of. In addition, as shown in FIG. 6, stepped engagement rails 28 having horizontal flanges 27 located at the left and right upper end portions of the transfer cylinder 23 are bent, while the connection frame 21 has left and right upper end portions. A step-shaped guide rail 30 having a horizontal flange 29 is bent. When the transfer cylinder 23 of the carry-out conveyor 4 is attached to the connection frame 21, the engagement rail 28 and the guide rail 30 are arranged so that the horizontal flange 27 of the transfer cylinder 23 is overlapped with the horizontal flange 29 of the connection frame 21. By engaging and sliding the engagement rail 28 along the guide rail 30, the transfer cylinder 23 of the carry-out conveyor 4 is connected to the connection frame 21, and the transfer cylinder 23 is moved to a predetermined position of the connection frame 21. After that, the connecting frame 21 and the transfer cylinder 23 are fixed with bolts and nuts 31. In the figure, reference numeral 36 denotes a support leg of the base 6.

  In the basic base unit 7 or the base unit 8 in the present invention, as in a normal sorter, the granules put into the feeding hopper 12 are supplied to the sorting cylinder 10 and sorted according to the particle size of the granules. That is, the small crushed particles having passed through the mesh of the sorting cylinder 10 fall to the trash collecting hopper 20 disposed in the lower part of the sorting cylinder 10 and are guided from the connecting frame 21 to the unloading conveyor 4 and screwed. By rotating 22, it is discharged from the discharge pipe 25. On the other hand, the sized particles remaining without passing through the mesh of the sorting cylinder 10 are collected along the inclination of the sorting cylinder 10 from the discharge end portion 10b of the sorting cylinder 10 to the sized particle collecting hopper 35. By using the component type grain sorting machine 1 in which the unit 7 and the base unit 8 are combined, it is possible to select an optimum sorting method from a plurality of sorting methods according to the sorting purpose desired by the customer. A selection method based on the combination of the basic base unit 7 and the base unit 8 will be described.

  As described above, for example, the basic base unit 7 having a single sorting cylinder 10 or the multistage type base unit 8 having two upper and lower sorting cylinders 10 is selected according to the amount of processing of the granules to be sorted. If the base unit 7 or the base unit 8 is used alone, as shown in FIG. 1 (a) or FIG. 1 (b), normal sorting, that is, as described above, the granules put into the feeding hopper 12 are sorted by the sorting cylinder 10. The waste particles having a particle size equal to or smaller than the reference value that has passed through the mesh of the sorting cylinder 10 are discharged by the carry-out conveyor 4 and the sized particles that have exceeded the reference value that has not passed the mesh of the sorting cylinder 10 are sized and collected. The product is discharged from the hopper 35 to the outside of the machine and, for example, packed in a bag.

  Further, the two base units 8 and 8 can select the granules in multiple stages. That is, as shown in FIG. 1 (c), base units 8 and 8 are provided side by side, and the sized particles selected by one of the base units 8 are lifted from the chute 5 of the sized particle collection hopper 35 (see FIG. 1). By continuously supplying to the charging hopper 12 of the other base unit 8 by the transfer conveyor 40 equipped with a not-shown) and sorting the particles again by the other base unit 8, it becomes possible to sort with higher accuracy. In this case, the connecting frame 21 of one base unit 8 is on the front side and the connecting frame 21 of the other base unit 8 is on the rear side so that the carry-out conveyors 4 of the two base units 8 and 8 provided adjacent to each other are adjacent to each other. It is desirable that the carry-out conveyor 4 of the two base units 8 and 8 is arranged in the center as the component type grain sorter 1 as a whole.

  Further, the component type grain sorting machine 1 in which the base unit 8 and the basic base unit 7 are combined can be used, and the waste grain that has been sorted by one base unit 8 and sieved can be sorted by the other basic base unit 7. That is, as shown in FIG. 1 (d), the base unit 8 and the basic base unit 7 are provided side by side, and the sized particles remaining after sorting by one of the base units 8 are carried out from the sized particle collection hopper 35. On the other hand, the waste particles screened off by the base unit 8 are continuously supplied from the discharge pipe 25 of the carry-out conveyor 4 to the supply unit 3 of the other basic base unit 7 by the transfer conveyor 40 equipped with a lifting mechanism (not shown). Thus, a re-sorting method that sorts two kinds of particles having different sizes by sorting with the sorting cylinder 10 of the basic base unit 7 becomes possible. In this case, as in the multi-stage sorting shown in FIG. 1 (c), it is not necessary to place the carry-out conveyor 4 of the two base units 8 and 8 close to the center of the component type grain sorter 1, It is more efficient that the carrying directions of the carry-out conveyors 4 of the base unit 8 and the basic base unit 7 are different from each other. That is, if the conveying direction of the carry-out conveyor 4 of each of the base unit 8 and the basic base unit 7 is reversed, the sized particles discharged from the base unit 8 and the sized particles and waste particles discharged from the basic base unit 7 Since the discharge direction can be aligned, it is extremely efficient. In the re-sorting of the granule, as shown in FIG. 1 (d) from the discharge efficiency of the base unit 8 and the basic base unit 7, the conveying direction of the unloading conveyor 4 of the base unit 8 and the basic base unit 7 is determined. Although it is advantageous to change it, it is not always necessary to make the transport directions of the unloading conveyors 4 of the base unit 8 and the basic base unit 7 different from the viewpoint of the function of re-sorting.

  Furthermore, it is possible to perform parallel sorting in which two base units 8 and 8 are simultaneously operated to increase the sorting processing speed (sorting processing amount). That is, as shown in FIG. 1 (e), two base units 8, 8 are provided side by side, and particles can be simultaneously selected by the respective base units 8, 8. In parallel sorting, two basic base units 7 can be provided side by side, but the combination of the base units 8 including the two-stage sorting cylinders 10 is preferable for the purpose of increasing the sorting processing amount. In this parallel sorting, as in the multi-stage sorting shown in FIG. 1C, it is desirable that the unloading conveyor 4 of each base unit 8, 8 is arranged close to the center of the component type grain sorting machine 1.

  As described above, in the present invention, the sorting unit 2 that sorts the granules, the supply unit 3 that supplies the granules to the sorting unit 2, the carry-out conveyor 4 that discharges the waste particles that have passed through the mesh of the sorting unit 2, A shoot 5 for carrying out the sized particles sorted by the sorting unit 2 and a base 6 for fixing them are used as basic components, and these basic components are combined to form a basic base unit 7 having a single sorting cylinder 10 and a plurality of upper and lower parts. By configuring the base unit 8 in which the sorting cylinders 10 are arranged in multiple stages, the basic base unit 7 and the base unit 8 can be arbitrarily combined to form the component-type grain sorting machine 1, thereby selecting a sorting method according to customer needs. Is possible. That is, except that the base unit 7 or the base unit 8 alone is operated and normally sorted, two base units 8 are provided side by side, and the sized particles sorted by one base unit 8 are reused by the other base unit 8. Multi-stage sorting for re-sorting, or the base unit 8 and the basic base unit 7 are provided side by side, and the re-sorting for sorting the waste particles screened and screened by one base unit 8 by the other basic base unit 7 or simultaneously A sorting method can be selected according to customer needs such as parallel sorting in which two base units 8 (or basic base units 7) are provided side by side and sorted by each base unit 8 (or basic base unit 7). In addition, the area occupied by the component-type grain sorter 1 is small and the entire device can be downsized to save space, and an optimal layout according to the needs of the customer is possible. A wide variety of sorting is possible and rational.

  Further, depending on the combination of the basic base unit 7 and the base unit 8, the waste particle carrying direction and the positional relationship in the front-rear direction of each carrying conveyor 4 with respect to the component type particle sorting machine 1 are different. As shown, when the arrangement of the carry-out conveyor 4 is changed, the connecting frame 21 that relays the waste particle collection hopper 20 and the carry-out conveyor 4 moves the position of the carry-out conveyor 4 back and forth (in the axial direction of the carry-out conveyor 4). And is attached so as to be detachable with respect to the waste particle collection hopper 20, while the carry-out conveyor 4 for carrying out the waste particles is connected to the connecting frame 21. Therefore, when changing the conveying direction of the waste particles, the engagement rail 28 of the unloading conveyor 4 can be slid along the guide rail 30 of the connecting frame 21. By sampling the unloading conveyor 4 from the connection frame 21 can be detached easily unloading conveyor 4 by simply sliding to plug by reversing the direction of the unloading conveyor 4 to guide rails 30 of the connecting frame 21. Thereby, the layout of the carry-out conveyor 4 and the conveyance direction of the waste particles by the carry-out conveyor 4 can be easily changed.

  Further, when sorting the granules in the basic base unit 7, the damper 16 provided in the input hopper 12 opens the sorting cylinder supply pipe 18 and closes the carry-out conveyor supply pipe 19. Although the supply destination is controlled, by switching the damper 16 so as to close the sorting pipe supply pipe 18 and open the carry-out conveyor supply pipe 19, the granules supplied into the charging hopper 12 are Without being sorted by the sorting cylinder 10, it is supplied to the carry-out conveyor 4 of the basic base unit 7, and the carry-out conveyor 4 can be used simply as a granule transfer conveyor. Can increase the sex.

  7 to 11 show a second embodiment of the present invention. Since only the configuration of the supply unit 50 is different from the first embodiment and the other configurations are substantially the same, common portions are denoted by the same reference numerals. The description of the overlapping parts is omitted, and only different parts are described. Further, the charging hopper 51 of the present embodiment can be mounted on the basic base unit 7 or the base unit 8 of the first embodiment and various types of combinations of the basic base unit 7 and the base unit 8. Only the basic base unit 7 and a combination of the basic base unit 7 and the base unit 8 will not be described in detail.

  The charging hopper 51 of the supply unit 50 in the present embodiment has a box shape as a whole, and forms a granule charging port 52 on the upper surface, and forms a feeding port 53 to the sorting cylinder 10 on the lower side. A suction connection pipe 55 that sucks the air in the charging hopper 51 is formed facing a drop path 54 that connects 52 and the supply port 53. Further, a suction pipe 56 is connected to the waste particle recovery hopper 20 and is located on the terminal end side of the carry-out conveyor 4, that is, on the discharge pipe 25 side of the carry-out conveyor 4, and communicates with the suction connection pipe 55. ing. The component type grain sorter 1 of the present invention extracts the unloading conveyor 4 from the connecting frame 21 by sliding the engaging rails 28 of the unloading conveyor 4 along the guide rails 30 of the connecting frame 21. The conveyor 4 can be easily attached and detached simply by reversing the direction of the conveyor 4 and sliding it so as to be inserted into the guide rails 30 of the connection frame 21. When changing the transport direction, the suction pipe 56 formed in the waste particle collection hopper 20 is formed on the surface of the carry-out conveyor 4 facing the discharge pipe 25.

  A pair of first outside air introduction ports 57 for introducing outside air located on both sides of the introduction port 52 are formed on the upper surface of the introduction hopper 51, and are formed by a dust collection unit (not shown) connected to the suction connection pipe 55. Air is sucked into the charging hopper 51 from the first outside air introduction port 57 by the air suction action. In addition, a guide plate 59 is formed inside the charging hopper 51 to guide the granules put into the charging hopper 51 to the lower flow rate adjusting plate 58. The guide plate 59 is formed at a distance from the outer surface of the charging hopper 51, and an air passage 60 for outside air introduced from the first outside air introduction port 57 between the guide plate 59 and the charging hopper 51. The external air sucked from the first external air introduction port 57 generates an air flow A that is sucked into the suction connection pipe 55 through the air passage 60, and this air flow A is supplied to the input port 52 and the supply port. It intersects with a fall path 54 connecting 53. The first outside air introduction port 57 is covered with a mesh for preventing scattering.
