  Next, a specific configuration of the soot supply amount adjusting device 24 that is a feature of the present invention will be described. FIG. 5 is a side view showing the entire soot supply amount adjusting device, and FIG. 6 is a perspective view of the lower portion of the soot supply amount adjusting device. A sensing valve 25 wide in the left-right direction of the machine body, which is housed in the mixed rice tank 4, is operated so as to rotate back and forth around the fulcrum shaft 26 as a change in the amount of mixed rice. Reference numerals 27 and 28 are stoppers for restricting the operation amount of the sensing valve 25, and reference numerals 29 and 30 are mixed rice cereal boards.

  The end of the fulcrum shaft 26 at the upper end of the sensing valve 25 is sequentially interlocked with an arm 31 and a connecting rod 32 extending downward. Further, the lower part of the arm 33a connected to the lower end of the connecting rod 32 has a pin shaft 34 projecting through the rear part of the arm 33b having a sled member 33c fixed at the rear end thereof. A rod supply interruption working metal 35 fitted into the shape hole and a rod supply amount adjusting working metal 36 connected to the front end of the arm 33b and having a long hole at the bottom are provided. An operation off switch 37a and an on switch 37b of the swing sorting plate 18b are provided above and below the rear portion of the soot supply interruption working metal 35.

  As shown in FIG. 6, the rod supply interruption operating gold 35 and the rod supply amount adjusting gold 36 are actuating rods 40 for operating the rod supply adjusting valve 38 via an operating plate 39 via an arm or the like, respectively. Will be linked sequentially. Further, the hull supply adjusting valve 38 is mounted above the hulling roll 11c and pivots up and down with a fulcrum shaft 41 fitted into the lower portion of the operating plate 39 as a fulcrum, so that the amount of hull supplied to the hulling roll 11c is increased. Adjustments or interruptions are made.

  Further, adjustment nuts (rod length adjusting mechanisms) 43, 44, and 45 such as turnbuckle mechanisms capable of adjusting the rod length are provided at the lower part of the connecting rod 32 and the front and rear parts of the operating rod 40, respectively.

  FIG. 7 is a side view showing the posture position of the sensing valve 25 according to the amount of mixed rice in the mixed rice tank 4, and FIGS. 8A to 8D are rice bran feeding according to the posture position of the sensing valve 25. It is a side view which shows the operation state of the operating metal 35 for interruption, and the operating metal 36 for the soot supply amount adjustment. Therefore, for example, when the hulling operation is not performed, when the sensing valve 25 is in the suspended posture a in which the sensing valve 25 is in contact with the stopper 27, as shown in FIG. Since the pin shaft 34 is located in the upper part of the substantially trapezoidal hole of the hook supply interruption working metal 35, no load is applied to the bottle supply interruption working gold 35, and the hook supply interruption working gold 35 does not operate. On the other hand, since the actuating rod 40 is positioned rearward, the soot supply adjusting valve 38 is fully opened at position a. Further, at this time, when the sled member 33c comes into contact with the operation off switch 37a of the swing sorting plate 18b, the swing sorting plate 18b is stopped and the mixed rice is not sorted.

  Here, when the shutter is opened by the operation lever 23b and the rice hulling operation is performed, the amount of mixed rice in the mixed rice tank 4 is slightly increased, and the sensing valve 25 is moved from the posture a to the posture b or from the posture b. When operated in the dead zone a, as shown in FIG. 8 (b), the connecting rod 32 is pushed down, but the pin shaft 34 slides in the vicinity of the center of the substantially trapezoidal hole of the rod 35 for interrupting the rod supply interruption. As a result, the rod 35 is not operated, and the lower portion of the rod supply amount adjusting rod 36 is pushed down by the rear portion of the interlocked arm 33b, so that the pivot A is the axis. It only pivots forward, and the hull supply regulating valve 38 is kept fully open, and the amount of hull supplied to the hulling roll 11c cannot be changed.

  Next, when the amount of mixed rice in the mixed rice tank 4 increases and the sensing valve 25 is operated in the band from posture b to posture c or from posture c to posture b, as shown in FIG. Then, the connecting rod 32 is further pushed down, and the pin shaft 34 is brought into contact with the lower end of the substantially trapezoidal hole of the rod supply interruption working metal 35 and follows the rotation support point B as an axis. The lower part is rotated forward.

  At the same time, the lower part of the rod 36 for adjusting the supply amount of the rod is further rotated forward about the rotation fulcrum A by pushing down the rear part of the arm 33b, so that the other end of the arm 42 protruding from the operation rod 40 is provided. Is pushed by the rear end of the long hole of the rod supply amount adjusting operation metal 36, the operating rod 40 slides forward, the rod supply adjusting valve 38 is moved to the position A and the fully opened state is reduced, and the rod is slid. The amount of soot supplied to the roll 11c is reduced. At this time, when the sled member 33c comes into contact with the operation ON switch 37b of the swing sorting plate 18b, the swing sorting plate 18b is operated and the mixed rice is sorted.

  Then, when the amount of mixed rice in the mixed rice tank 4 increases until it reaches a predetermined position, and the sensing valve 25 is moved from the posture c to the posture d in contact with the stopper 27, the state shown in FIG. As shown in the figure, the connecting rod 32 is further pushed down, and the pin shaft 34 follows the rotation of the connecting rod 32 while keeping the substantially trapezoidal hole lower end of the rod supply interruption working metal 35 in contact with the pivot fulcrum B as an axis. The lower part of the working metal 35 is further rotated forward.

  As a result, the operating rod 40 is further slid forward, and the soot supply adjusting valve 38 is actuated to the position C to be fully closed, thereby interrupting the soot supply. At this time, the sled member 33c is kept in contact with the operation ON switch 37b of the swing sorting plate 18b, and the mixed rice is sorted by the swing sorting plate 18b.

  In this way, the amount of mixed rice that fluctuates in the mixed rice tank 4 is rotated by the operation amount of the sensing valve 25 through the one connecting rod 32 and the operation supply metal 35 for interrupting the supply of rice cake and the operation gold 36 for adjusting the supply amount of rice cake. By moving, the mixed rice supply to the sorting unit 18 is adjusted, and the straw supply control valve 38 is opened and closed to adjust the amount of straw supplied to the hulling roll 11c, thereby improving the assembly and maintenance of the apparatus. be able to.

  In addition, since the soot supply interruption working metal 35 and the soot supply amount adjusting working metal 36 are provided, the operation amount of the soot supply adjusting valve 38 can be changed separately between when the soot supply amount is adjusted and when it is interrupted. The amount of straw supplied to the hulling roll 11c can be stabilized. Further, since the operation switches 37a and 37b of the swing sorting plate 18b are provided below the connecting rod 32 and in the vicinity of the rod supply interruption working metal 35, the linkage between the hulling roll 11c and the swing sorting plate 18b is interlocked. The operability of the apparatus can be improved.

  Here, for example, when the length of the connecting rod 32 is increased and the rocking sorting plate 18b is to be operated before the amount of mixed rice in the mixed rice tank 4 reaches the predetermined position as described above, the adjustment nut is used. 43 is adjusted to lengthen the connecting rod 32. Thus, by adjusting the adjustment nut 42, it is possible to change the timing of stopping or operating the swing sorting plate 18b according to the amount of mixed rice in the mixed rice tank 4.

  Similarly, by adjusting the adjustment nut 44 provided at the front part of the operating rod 40 and changing the length of the operating rod 40, the timing at which the rod supply amount adjusting operation metal 36 starts to rotate can be adjusted. For example, it is possible to change the operation timing of the soot supply control valve 38 by elongating the operating rod 40 and increasing the timing at which the soot supply control valve 38 starts to close depending on the amount of mixed rice in the mixed rice tank 4.

  Furthermore, by adjusting the adjustment nut 45 provided at the rear portion of the operating rod 40 and changing the length of the operating rod 40 in the same manner as described above, the timing at which the operation supply rod 35 for suspending the rod supply starts to be adjusted can be adjusted. For example, it is possible to change the supply interruption timing of the soot supply by, for example, lengthening the operating rod 40 and increasing the timing for fully closing the soot supply control valve 38 according to the amount of mixed rice in the mixed rice tank 4.

  Thus, since the turnbuckle mechanism such as the adjusting nuts 43, 44, 45 is provided on the connecting rod 32 and the actuating rod 40, the operation of adjusting the amount of supply and the interruption of the supply of the soot by the swing sorting plate 18b and the soot supply adjusting valve 38. The timing can be changed independently, and the operability of the apparatus can be improved.
