  A conveyance control device 88 (conveyance operation unit) is provided on the side of the vertical intermediate portion of the elevator 82 (on the right side in the present embodiment), and the conveyance screw 78B of the conveyance mechanism 78 is controlled by the conveyance control device 88. While being driven and rotated, the elevator 82 is driven. A discharge level sensor 86 is electrically connected to the transfer control device 88. When the discharge level sensor 86 detects that the amount of the selected grain in the discharge tank 84 is equal to or greater than a predetermined value, the transfer control is performed. Under the control of the device 88, the rotation of the conveying screw 78B is stopped.

  Next, the operation of this embodiment will be described.

  In the sorting apparatus 10 having the above configuration, the sorting material (at least the sorted grain and the foreign matter) is supplied into the supply hopper 20 from the upper side, so that the sorting material is supplied from the supply hopper 20 into the sorting drum 42. Further, the supply amount of the sorting raw material from the supply hopper 20 to the sorting drum 42 is adjusted by adjusting the moving operation position of the shutter 20A.

  Further, under the control of the sorting control device 46, the sorting drum 42 is driven and rotated to one side in the circumferential direction (the arrow A side in FIG. 1 etc.), so that the sorting raw material in the sorting drum 42 is moved by the sorting drum 42. It is gradually moved from the front side to the rear side while being stirred. In addition, since the stirring plate 68 in the sorting drum 42 is rotated integrally with the sorting drum 42, the sorting raw material in the sorting drum 42 is stirred by the stirring plate 68. For this reason, the selected grain in the selected raw material is sorted by passing through the sorting hole 64A of the sorting plate 64 of the sorting drum 42 and dropping. Further, the foreign material in the sorting raw material is moved rearward without passing through the sorting hole 64A, and is moved from the discharge port 52 of the sorting drum 42 (frame 48) to the transport path 34A of the transport frame 34 outside the sorting drum 42. Discharged.

  The selected grain that has passed through the sorting hole 64A of the sorting drum 42 is dropped onto the conveying basket 78A of the conveying mechanism 78, and flows down onto the central portion in the left-right direction of the conveying basket 78A. Furthermore, by the conveyance control device 88 being controlled, the conveyance screw 78B of the conveyance mechanism 78 is driven and rotated, whereby the selected grains on the central portion in the left-right direction of the conveyance rod 78A are conveyed rearward by the conveyance screw 78B. Then, it is supplied into the lower end of the elevator 82. Moreover, when the elevator 82 is driven by the control of the conveyance control device 88, the selected grains in the lower end portion of the elevator 82 are raised by the elevator device in the elevator 82 and supplied into the discharge tank 84. For this reason, the selected cereal in the discharge tank 84 is discharged through the inside of the selected discharge cylinder 84A on the lower wall of the discharge tank 84, and is supplied to the next process device (for example, a grain drying device).

  On the other hand, the foreign matter discharged to the transport path 34A of the transport frame 34 is rotated integrally with the sorting drum 42 by the transport scraper 74 of the sorting drum 42 (frame 48), and the transport path 34A is moved to the sorting drum 42 by the transport scraper 74. By being transported to one side in the circumferential direction, it flows down the discharge path 36 </ b> A of the discharge frame 36 and is discharged to the right side of the upper box 16.

  Further, when the adjustment plate 32 is attached to the lower box 14, the adjustment hole 32 </ b> B of the adjustment plate 32 through which the tilt shaft 30 of the tilt base 22 passes is selected, and the vertical position of the tilt shaft 30 is adjusted. Thereby, the downward inclination angle of the rear portion with respect to the front portion of the connecting shaft 26 of the inclined base 22 is adjusted, and the downward inclination angle of the rear portion with respect to the front portion of the sorting drum 42 in the axial direction is adjusted. Therefore, the accuracy with which the selected grains pass through the selection hole 64A of the selection drum 42 is adjusted by adjusting the speed at which the selection drum 42 is rotated and the selection raw material in the selection drum 42 is moved from the front side to the rear side. The accuracy in which the selected grain is not discharged from the outlet 52 of the sorting drum 42 and the precision in which the foreign matter is discharged from the outlet 52 of the sorting drum 42 are adjusted, and the sorting accuracy of the selected grain by the sorting device 10 is adjusted. Is done.

  Here, the sorting drum 42 is cylindrical. For this reason, when the sorting drum 42 is rotated, the sorting material in the sorting drum 42 can be conveyed to a high position, and the sorting material can be effectively stirred in the sorting drum 42. Thereby, the selected grain can efficiently reach the peripheral wall of the sorting drum 42, the sorting efficiency of the selected grain can be increased, and the sorting raw material can be prevented from being clogged in the sorting hole 64A of the sorting drum 42. In addition, the sorting drum 42 can be rotated with a simple configuration, the configuration of the sorting device 10 can be simplified, and the manufacturing cost of the sorting device 10 can be reduced.

  Further, the sorting drum 42 is formed in a polygonal cylindrical shape. Therefore, by rotating the sorting drum 42, the sorting raw material in the sorting drum 42 can be conveyed to a higher position, and the sorting raw material can be stirred more effectively in the sorting drum 42. As a result, the selected grains can reach the peripheral wall of the sorting drum 42 more efficiently, and the sorting efficiency of the selected grains can be further increased, and the sorting raw material is further blocked in the sorting holes 64A of the sorting drum 42. Can be suppressed.

  Further, a weir plate 54 in the sorting drum 42 (frame 48) is disposed in front of the discharge port 52 of the sorting drum 42, and restricts the movement of the selected grains in the sorting raw material to the discharge port 52 side. For this reason, it is possible to promote that the selected grain passes through the selection hole 64A of the selection drum 42 and be selected, and it is possible to prevent the selected grain from being discharged from the discharge port 52. Thereby, the precision by which the selected grain passes through the sorting hole 64A and is selected, and the precision that the selected grain is not discharged from the discharge port 52 can be improved, and the sorting precision of the selected grain by the sorting apparatus 10 can be improved.

  Further, a comb 70 (a plurality of comb plates 70A) in the sorting drum 42 (frame 48) is arranged on the front side of the weir plate 54, and the comb 70 is rotated integrally with the sorting drum 42, so that the inside of the sorting raw material The foreign matter is caught and rotated by the comb 70 (comb plate 70A) and then released to the inner peripheral side of the sorting drum 42, and the selected grain in the selected raw material passes through the comb 70 (between the comb plates 70A). Is allowed to. For this reason, it can suppress that the weir board 54 restrict | limits the movement to the discharge port 52 side of a foreign material, and can discharge | emit a foreign material from the selection port 42 favorably from the discharge port 52. FIG. Furthermore, it can suppress that a selected grain is discharge | released by the comb 70 to the inner peripheral side of the selection drum 42, and can suppress that a selected grain is still discharged | emitted from the discharge port 52. FIG.

  In addition, a guide plate 72 in the sorting drum 42 is disposed on the front side of the discharge port 52, and guides foreign matter in the sorted raw material to the discharge port 52 across the weir plate 54. For this reason, it can suppress further that the weir board 54 restrict | limits the movement to the discharge port 52 side of a foreign material, and can discharge | emit a foreign material from the discharge port 52 out of the selection drum 42 still more favorably. Further, a guide plate 72 is disposed on the opposite side of the comb 70 in the circumferential direction of the sorting drum 42. For this reason, the guide plate 72 can satisfactorily guide the foreign matter discharged to the inner peripheral side of the sorting drum 42 by the comb 70, and the foreign matter can be better discharged from the sorting port 42 to the outside of the sorting drum 42.

  Further, as described above, the conveying scraper 74 of the sorting drum 42 is rotated integrally with the sorting drum 42, whereby the conveying scraper 74 conveys the foreign matter on the conveying path 34 </ b> A of the conveying frame 34 to the upper side of the lower end of the sorting drum 42. To do. For this reason, it is possible to increase the discharge position of the foreign matter from the discharge path 36A of the discharge frame 36 in the tilting table 22, and to arrange the foreign substance receiving port of the foreign substance receiver (such as a bag) that receives the foreign substance discharged from the discharge path 36A high. The foreign matter can be easily received by the foreign matter receiver. Furthermore, it is possible to eliminate the necessity of providing the discharge frame 36 (discharge path 36A) below the lower end of the sorting drum 42, and the installation height of the sorting drum 42 in the sorting device 10 can be reduced. The degree of freedom of the installation position of the sorting drum 42 can be improved. In addition, since the transport scraper 74 is rotated integrally with the sorting drum 42, it is not necessary to separately provide a driving device for rotating the transport scraper 74.
