  A hopper 5 for supplying cereals is provided on the back surface of the base body 2, and the supply cylinder 4 is disposed below the base body 2 in communication with the hopper 5. The supply cylinder 4 has a bottomed cylinder shape with an open upper surface, and the guide cylinder 10 is disposed in the supply cylinder 4.

  As shown in FIG. 4, the guide tube 10 disposed in the supply tube 4 forms a plurality of supply ports 11 on the lower peripheral surface, and forms a spiral guide blade 12 on the top of the supply port 11, Further, a band-like net-like body 13 for selecting ridges is formed on the upper part. Further, a pair of upper and lower circular flange portions 14 and 15 are provided so as to sandwich the upper and lower sides of the mesh-like body 13, and the lower ends of the sorting mesh body 20 are provided on the engaging pieces 16 and 16 projecting on the upper flange portion 14. An engaging slit 19 provided in the portion engages, and a sorting net 20 is placed on the upper portion of the guide tube 10. Due to the engagement between the engaging piece 16 of the guide tube 10 and the engagement slit 19 of the sorting net body 20, the guiding tube 10 and the sorting net body 20 are integrally rotated. In the sorting net body 20, the above-mentioned threshing spiral cylinder 30 is disposed concentrically. A rotary shaft 30 a is integrally formed at the upper end portion of the cerealing spiral cylinder 30, and the cerealing spiral cylinder 30 is attached to the sorting net body 20 by a bearing 21 formed on the upper end portion of the sorting net body 20. To enable relative rotation. Further, the rotary shaft 30a is pivotally supported by a bearing 22 that passes through the bearing 21 and is fixed to the base 2. As a result, the sorting net body 20 rotates at a low speed together with the guide cylinder 10, and the cerealing spiral cylinder 30 is coaxially rotated at a high speed, and the circumference of the cerealing spiral cylinder 30 disposed concentrically in the sorting net body 20. The cereals supplied between the sorting net body 20 and the cerealing spiral cylinder 30 are cerealed by the spiral blades 31 formed on the surface.

Grain introduced into the supply cylinder 4 from the insertion port 5 a of the hopper 5 is guided downward by the guide blade 12 of the guide cylinder 10 and enters the guide cylinder 10 from the supply port 11 opened at the lower part of the guide cylinder 10. Led. Next, the grain is introduced between the sorting net body 20 and the cerealing spiral cylinder 30, and the grain is first formed in the guide cylinder 10 while the cereal is being ceased by the relatively rotating sorting net body 20 and the cerealing spiral cylinder 30. A ridge is passed through the mesh of the mesh body 13. Thereafter, cracked rice and small grain rice are allowed to pass through the mesh of the sorting mesh body 20, and good grains that do not pass through the mesh of the sorting mesh body 20 are discharged to the storage tank 3. It is configured to sort cereals. The size of a large number of sorting openings formed in the sorting net 20 is determined in accordance with the size of good grains, and the size of the opening (mesh) of the net 13 formed in the guide tube 10 is narrower than that. A partition plate 17 (shown in FIG. 7) is attached to the inside of the base body 2 so as to correspond to the upper side flange portion 14 of the guide tube 10, and the inside of the base body 2 is made upper by the partition plate 17 and the upper side flange portion 14. It is divided into a discharge path 18a and a lower discharge path 18b. The flange portion 14 and the partition plate 17 are provided in contact with each other. A small rice discharge chute outlet 7 is provided facing the upper discharge path 18a, and a detachable scraping box 8 is provided below the lower discharge path 18b. Is provided. And the rice cake that has passed from the mesh of the mesh body 13 of the guide tube 10 is discharged to the rice picking box 8 through the lower discharge passage 18b, and the broken rice such as broken rice and small grain rice that has passed the mesh of the sorting mesh body 20 is removed. It is discharged to the small rice discharge chute 7 through the upper discharge path 18a. A discharge port 70 is provided at the lowermost part of the supply cylinder 4 and is configured to be opened and closed by a lever 71 and the like.

  As shown in FIGS. 5 (a) and 5 (b), the details of the scraping box 8 are formed in a box shape having an open upper surface, and holding and positioning ribs 8a projecting vertically on both sides thereof. At the same time, the front plate 9 of the scissor box 8 is formed with a pair of left and right recesses 9a, 9a (FIG. 2) for finger hanging. Furthermore, if the translucent portion 9b is formed on the front plate 9, the amount of soot accumulated in the soot removal box 8 can be seen from the outside. In order to hold and position the scraping box 8 in the base body 2, a concave (pocket-shaped) storage portion 25 for storing the scraping box 8 is formed at the lower side of the base body 2. A pair of left and right inverted V-shaped receiving ribs 26 for guiding the positioning ribs 8a are formed on the left and right side walls (FIG. 5C). As shown in FIG. 5C, the scooping box 8 is inserted into the storage portion 25 from the lower end portion, and the lower end portion of the positioning rib 8a is guided into the rear inclined surface 26a of the receiving rib 26, thereby The staking box 8 is easily positioned and held. When taking out the wrinkle-removing box 8, the reverse may be performed.

  The storage tank 3 communicates with a discharge port 2 a provided in the base 2, and a discharge port 3 a for good grains a is provided at a lower portion of the storage tank 3. An operation panel 52 having various display units 50 and various operation switches 51 is arranged on the front side of the storage tank 3. A U-shaped handle 55 is attached to the lower part of the operation panel 52. The vertical grain sorter is moved by the casters 1 a and 1 b provided on the base 1 by grasping the handle 55. A fixed caster 1a is arranged on the back side of the base 1, and a universal caster 1b is arranged on the front side. The handle 5 is held and the vertical caster 1b is moved while changing the direction of the vertical grain sorter. After moving the vertical grain sorter to the position, the position of the vertical grain sorter is fixed by extending the installation leg 6 attached to the base 1. In addition, symmetrical light-emitting display portions 56 are provided across both sides of the front surface of the handle 55. As shown in FIG. 6, the light-emitting display unit 56 includes four sets of light-emitting areas 58 a to 58 d made of a light emitter 57 such as an LED, for example, and these light-emitting areas 58 a to 58 d are processing conditions of the good grain a to be selected. For example, it controls so that it may light according to the remaining amount of good grain a. For example, when the display operation panel 52 is set so as to sort 30 kg of good cereals, the left and right light emitting display portions 56 are sequentially arranged from the light emitting areas 58d to 58c, 58b, 58a on the back side every time 7.5 kg is sorted. Are controlled so that the remaining amount of the good grain a is known to the user by the light emitting state of the light emitting display unit 56. When sorting is completed, the entire light emitting area blinks, so that higher visibility can be obtained. In that case, it is also possible to emit an end warning sound at the same time. The light emitting regions 58a to 58d are covered with the translucent cover 59, but FIG. 6 shows a state where the translucent cover 59 is removed.

  The U-shaped handle 55 is arranged a predetermined distance away from the storage tank 3 so that a hand can be inserted (FIG. 10). At that time, both U-shaped end portions are firmly fixed by fixing means 51a, 51b such as bolts. Note that the wires 58m for feeding power to the light emitting elements constituting the four pairs of light emitting regions (58a to 58d) (58a to 58d) are wired together from the feeding wire opening 55a at the center. It is also possible to wire between the U-shaped handle 55 and the storage tank 3 through the protective tube 59a so that the power supply wire 58m is not exposed to the outside.

  Further, in order to confirm the cereal selection state in the base body 2 on both sides of the base body 2, confirmation window portions 60 are provided on both sides of the middle portion of the sorting net body 20. A bulging cover 61 bulging outwardly is fitted in the window 60, and the clogging of the sorting net 20 is confirmed from the bulging cover 61. Another reason why the bulging cover 61 is bulged is also for convenience when the guide tube 10 is mounted in the base 2 as described later.

  Further, the front panel 2b of the base 2 is formed of a synthetic resin panel to reduce the weight. FIG. 9A is a rear view of the front panel 2b made of synthetic resin, and cooling ventilation openings 61, 61... Are formed in the lower part. Since the ventilation openings 61, 61... Weaken the strength of the front panel 2b, a convex reinforcing rib 62 is provided on the upper portion in the vicinity thereof. Since a wide surface is formed on the upper portion of the front panel 2b, a rectangular reinforcing step 65 is integrally formed so as to cover the entire large surface of the front panel 2b in order to reinforce it. Is done. An upper side portion of the reinforcing step portion 65 forms an opening 65a. A pair of upper and lower thin strips 66 are bonded to the back side of the reinforcing step 65. As a result, a space 65b having an open upper side between the pair of upper and lower thin strips 66 can be formed on the back surface of the reinforcing step 65. Thereby, it can utilize as an appropriate pamphlet etc., for example, the storage space of the instruction manual 67 of a vertical grain sorter.

  Next, the operation of this embodiment will be described. When the weight of good grains selected by the operation panel 52 is set and the cereal is supplied into the hopper 5, the cereal is introduced into the supply cylinder 4 from the introduction port 5a and is lowered by the guide blade 12 of the induction cylinder 10 rotating at low speed. And is introduced into the guide tube 10 from a supply port 11 formed in the lower portion of the guide tube 10. While the cereal introduced into the guide cylinder 10 is cerealed by the interaction between the spiral blade 31 and the sorting net 20 that rotates integrally with the guide cylinder 10 at a low speed, first, the lightest and lightest koji is guided. It passes through the mesh of the mesh 13 formed in the cylinder 10. Next, cracked rice or small grain rice passes through the mesh of the screening mesh body 20, and the good grain a that does not pass through the mesh of the screening mesh body 20 is raised to the upper part of the base 2, and scraped to rotate integrally with the screening mesh body 20. It is blown off by a blade (not shown) and discharged into the storage tank 3 from the discharge port 2a. The good grains a in the storage tank 3 are filled into a cereal bag (not shown) placed on a weighing machine (not shown) from a discharge port 3 a provided at the lower part of the storage tank 3. The weight of the good grain a filled in the cereal bag is output from the weighing machine to the control device of the vertical grain sorter, and the light emitter 57 provided on the handle 55 is controlled to be turned on according to the remaining amount of the good grain a. .

  Further, the soot that has passed through the mesh of the mesh body 13 formed in the guide tube 10 is discharged from the lower discharge path 18 b to the scooping box 8, and the scissors that have been removed from the base 2 and accumulated in the scooping box 8 are collected. Recover. The route discharged from the lower discharge path 18b to the scooping box 8 is not the gist of the present invention, and will not be particularly described. On the other hand, waste rice such as broken rice and small grain rice that has passed through the mesh of the sorting net body 20 is discharged to the small rice discharge chute 7 from the upper discharge path 18a, and is filled and recovered from the discharge chute 7 into a grain bag (not shown). . When removing the scissor box 8 from the base 2, as shown by a chain line in FIG. 5C, the receiving ribs 26 are supported by placing fingers on the recesses 9a, 9a for hooking the scooping box 8. As described above, the wrinkle box 8 can be easily removed simply by rotating the wrinkle box 8 slightly and pulling it up. On the other hand, when setting the scraping box 8, the scraping box 8 extends along the inclined surface 26 a of the receiving rib 26 by guiding the lower end of the positioning rib 8 a of the scraping box 8 into the inclined surface 26 a of the rib 26. An urging force a directed toward the inside of the base body 2 acts on the scissor box 8, and the front plate 9 of the scissor box 8 is thereby pressed against the base body 2, so that the scissor box 8 can be easily positioned in the storage unit 25. Can be held.

  Further, from the bulging cover 61, it is possible to check the state of the sorting net body 20 as to whether it is clogged. Furthermore, as shown in FIG. 7, when assembling the guide tube 10 in the base body 2, the guide tube 10 can be easily rotated using a space bulging outward formed by the bulging cover 61. it can. In the case of the present invention, the dimension H (FIG. 8) is increased by providing the mesh body 13 in the guide tube 10, but such a case can be easily dealt with. That is, when the guide tube 10 is incorporated into the base body 2, the guide tube 10 is inserted from the back side of the base body 2 and set in the supply tube 4 with the back cover (width 2 r) removed from the base body 2. However, since the upper discharge passage 18a and the lower discharge passage 18b are partitioned by the upper flange portion 14 of the guide tube 10 and the partition plate 17, the outer diameter R of the upper flange portion 14 of the guide tube 10 is set to Although it is slightly smaller than the inner width W, the outer diameter R and the inner width W of the base body 2 are set to be substantially the same in terms of design when attempting to make the base body 2 compact without increasing the size. On the other hand, in order to fix the back cover 2r to the base body 2, it is necessary to form a bent piece 2z as an overlap margin with the back cover 2r on the base body 2. For this reason, when the guide tube 10 is incorporated in the base body 2, the outer diameter R of the upper flange portion 14 of the guide tube 10 becomes larger than the opening width W <b> 1 of the base body 2. For this reason, the guide tube 10 is inserted into the base body 2 in a state where the guide tube 10 is tilted laterally (width H) (the height H of the guide tube 10 needs to be designed to be smaller than the opening width W1). Therefore, when assembling the guide tube 10 in the base body 2, the guide tube 10 is inserted into the base body 2 in a state where the guide tube 10 is tilted sideways (width H), and the guide tube 10 is rotated in the vertical direction in the base body 2. There is a need. At this time, the rotation space of the upper flange portion 14 (that is, the maximum on the diagonal line of the guide tube 10) is the portion of the bulge cover 61 that has a bulge on the outside (the inner surface distance W2 of the left and right bulge covers 61, 61). Dimension) can be ensured, and when the guide tube 10 is rotated, interference between the inner wall portion of the base 2 and the upper flange portion 14 can be prevented, and the assembly work of the guide tube 10 is also easy.

  As described above, according to the present embodiment, the cereal introduced from the hopper 5 into the supply cylinder 4 is introduced into the induction cylinder 10 from the supply port 11 of the induction cylinder 10 by the induction blade 12, and the cereal spiral cylinder 30 In the initial stage when the cereals are cerealed by the spiral blades 31, first, the rice cake 13 having the lightest specific gravity in the mesh body 13 formed in the guide tube 10 is passed through the mesh and then cracked rice and small grains in the mesh of the sorting mesh body 20. Since the good grain a that passes the rice and does not pass through the mesh of the sorting net body 20 is raised to the upper partition plate 17, it is possible to sort the straw early from the grain at the initial stage of the sorting. In addition, the soot that has passed through the mesh-like body 13 is discharged to the lower discharge path 18b defined by the partition plate 17 and the upper-side flange portion 14, and does not float over the entire base body 2. Clogging and adhesion of soot to the bearings 21 and 22 and various movable parts can also be suppressed. The scraping box 8 is detachable so that it can be removed from the base 2 when collecting the trapped soot. The mounting box 8 is attached to the base 2 by positioning ribs 8a of the scraping box 8. Just by receiving the lower end of the plate 26 into the inclined surface 26 a of the rib 26, the scooping box 8 moves to the inside of the base 2 along the tilted surface 26 a of the receiving rib 26, and the front plate 9 of the scooping box 8 is moved to the base 2. It can be pressed and easily positioned and held. On the other hand, the staking box 8 can be easily removed by simply rotating the staking box 8 slightly with the receiving rib 26 as a fulcrum and pulling it up.

  Further, the state of the sorting net body 20 such as clogging of the sorting net body 20 can be easily confirmed from the bulging cover 61, and the outer diameter R of the upper side flange portion 14 of the guide tube 10 and the opening width of the base 2. When assembling the guide tube 10 into the base body 2 due to the size of W1, when the guide tube 10 has to be inserted into the base body 2 in a lateral direction, it is swollen outward by the bulging cover 61. When the guide cylinder 10 that is tilted down using the space is raised, a space enough for the upper flange portion 14 to rotate can be secured by using the swelled space portion of the bulging cover 61. Thereby, when the guide tube 10 is assembled, interference between the inner wall portion of the base 2 and the upper flange portion 14 can be prevented, and the assembly operation of the guide tube 10 is also easy.

  Further, the handle 55 provided on the front surface of the base 2 is a portion to be gripped when the vertical grain sorter 1 is moved to a desired position, but the handle 55 provided on the front side of the base 2 is most prominent. By providing the light-emitting display unit 56 that emits light according to the remaining amount of good cereal a, the operator can be visually informed of the remaining amount of good cereal a to be sorted, and the operator has excellent visibility, and the operator It also has an excellent alarm function that prompts the user to be alerted. The light-emitting display unit 56 is provided symmetrically with the front part as the center, so that the vertical grain sorter 1 has a wide angle range from the left, right, or front of the vertical grain sorter 1. The operating status can be easily grasped.

  Furthermore, it is possible to reduce the weight by forming the front panel 2b of the base body 2 with a synthetic resin, and it is extremely rational by using the reinforcing step 65 of the front panel 2b as a storage space for the instruction manual 67. In addition, the instruction manual 67 that is easily lost can be stored in a conspicuous portion of the vertical grain sorter 1, and the loss of the instruction manual 67 can be prevented. Can be taken out easily.

  As mentioned above, although one Example of this invention was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the basic configuration such as the type and number of light emitters constituting the light emitting display unit and the shape of the cover may be selected as appropriate.
