The camera 76 is mounted on the screw shaft 78 so that the mounting machine base 77 moves up and down along the vertical screw shaft 78 so that the camera position can be finely adjusted up and down. Accordingly, since a wide range is measured over the vertical range, an appropriate position can be selected while adjusting in the vertical direction. Instead of this vertical movement, the camera 76 may be configured to swing up and down or up and down and left and right with respect to the mounting machine base 77 so as to be widely measured over the vertical range.

FIG. 8 shows an improvement of the unit selection unit provided in the shape of a platform. That is, the upper and lower sorting belts 81 and 82 are connected in series. The upper sorting belt 81 inclined in two planes has the same form as the sorting belt 25, while the lower sorting belt 82 has the same longitudinal inclination as the upper sorting belt 81 but the left and right inclinations are reversed. I am letting. A supply unit 83 is provided on the lower belt inclination side of the upper sorting belt 81 and can be supplied from the transfer terminal end of the upper sorting belt 81 toward the lower inclination side of the lower sorting belt 82 via the guide supply unit 84. . The guide supply unit 84 includes a switching valve 85 that switches between a supply state to the lower sorting belt 82 and a supply state to the outside of the machine as appropriate. The unit sorting portions of the upper and lower sorting belts 81 and 82 are framed by a frame 86 and can be stacked in a vertical pattern. The sized and collected hopper is disposed on the lower end side of the sorting belt 81 in the front-rear direction. The waste particle collection hopper is connected to the outside of the guide supply unit 84 or is provided in the upper discharge unit of the lower sorting belt 82.

If comprised as mentioned above, the supplied sorting soybean will be sorted by the upper sort belt 81, and it will be separated into the size regulation and the waste grain up and down. When the sizing ratio contained in the waste grains is high, sorting by the lower sorting belt 82 is performed. Thus, the particles are sorted into sized particles and waste particles through a vertically long sorting path. Here, when a desired sorting state can be obtained by the sorting action of the upper sorting belt 81, the switching valve 85 can be used to make a discharge state outside the machine so that the sorting by the lower sorting belt 82 is not performed.

FIG. 9 shows the structure of a clogging prevention body provided to remove clogging of the sorting holes of the rotary sorting cylinders 18 and 19. The shaft 90 linked to the forward / reverse driving means is configured as a square axis, and rubber pieces 91, 91... Are applied to each side of the square axis 90 with a length n appropriately short with respect to each side length m of the square axis 90. It fixes with the board 92,92 .... For this reason, in the forward rotation state (FIG. 9 (A)), the rubber piece 91 is in contact with the outer surface of the rotary sorting cylinder while being regulated by the end face of the adjacent backing plate 92 and sweeps off adhering soot and small rice. On the other hand, at the time of reverse rotation (FIG. 9 (b)), the rubber piece 91 can be deformed within a range in which the rubber piece 91 is curved and in contact with the bent portion 92a at the end of the contact plate 92. Since the side length of the shaft 90 is shorter, the effective action length G2 of the rubber piece 91 is longer than the effective action length G1 at the time of normal rotation. By making it act strongly, prevention of clogging can be promoted.
[0048]
Since the configuration disclosed in Japanese Patent Laid-Open No. 2002-177889 is a configuration that is driven and rotated in a certain direction, the rubber is deformed to promote deterioration. Further, if the elastic returnability is impaired by deformation, the contact surface is small and sufficient removal performance cannot be obtained. Therefore, as described above, the rubber piece is set on the shaft that can be linked in the forward / reverse direction so that its effective action length is set differently, so that the action at the time of reverse rotation becomes stronger than the normal forward rotation state and the clogging removal effect is promoted. be able to.
