On the other hand, it is always urged | biased by the said strip 10 in the direction of the rotating shaft 7 (arrow b 'direction, refer FIG. 9).

  4 and 5 show the connection relationship between the rice feed roller 6 and the sliding rotary shaft 9, the timing pulley 19 is connected to the rice discharge roller 5 and the sliding rotary shaft 9. The other components are the same.

  A circular recess 11 into which the columnar protrusion 7 ′ of the rotating shaft 7 can be fitted is formed at the center of the tip surface 9 ′ of the sliding rotating shaft 9. A male and female engaging groove 11 ′ is formed through the recess 11 in the passing radial direction (FIGS. 6A to 6C). The mutual angles of the male and female engaging grooves 11 ′ and 11 ′ in the sliding rotary shafts 9 and 9 at the positions where the rice feed rollers 6 and 6 are mounted are the same, and the male and female of both rotary shafts 9 and 9 are the same. The engaging grooves 11 ′ and 11 ′ are positioned so as to be in a positional relationship such that they are parallel to each other (see FIG. 8).

  That is, when the timing belt 21 is attached to the timing pulleys 19 and 19 attached to the sliding rotary shafts 9 and 9, as shown in FIG. 8 (a), each male and female corresponding to at least the rice feed rollers 6 and 6 is provided. The timing belt 21 is mounted in a state in which the positions of the engaging grooves 11 ′ and 11 ′ are parallel to each other. Thereafter, the male and female engaging grooves 11 ′ and 11 ′ are parallel to each other (at the same angle). ) It is configured to be able to rotate while maintaining the state. Thereby, in the state which connected the rice feed rollers 6 and 6 to the said sliding rotating shafts 9 and 9, it is comprised so that both the rollers 6 can rotate in the state holding the same phase.

  Then, as shown in FIG. 3, a driving timing belt 21 is wound around the timing pulleys 19 and 19 having the same diameter as the small-diameter driving timing pulley 13, and the belt 21 is tensioned by the pressing timing pulley 22.

When engaged with 11 ′ and 11 ′, the stirring blades 24 of the rice feed rollers 6 and 6 are configured to have a positional relationship that does not interfere with each other as shown in FIGS. Accordingly, by rotating the rotary shafts 9 and 9 at the same speed in such a connected state, the rice feed rollers 6 and 6 can rotate while maintaining the same phase where the stirring blades 24 do not interfere. .

  Since the three rotary shafts 7, 7, and 7 of the rice supply box 2 are only supported in a free state and their positions are arbitrary, the “rice feed roller” is set before the drive switch ON. 6 and 6 "are roughly aligned so that the agitating blades 24 of 6 and 6" do not cushion each other (the positional relationship in FIG. 1). In this state, when the rice supply box 2 is supported by the support rods 12 and 12 at the front and rear of the upper end portion of the machine casing 1, the three rotary shafts 7 projecting outside the one side plate 2 'of the supply box 2 are provided. , 7, 7, the tip surfaces 9 ′, 9 ′, 9 ′ of the sliding rotary shafts 9, 9, 9 are pressed against the protrusions 7 ′, 7 ′, 7 ′ by the force of the ridge 10.

  In this state, since the initial angles of the male and female engaging grooves 11 ′, 11 ′, 11 ′ of the sliding rotary shafts 9, 9, 9 are also arbitrary, for example, as shown in FIG. The male and female engaging grooves 11 ′, 11 ′, 11 ′ of the shafts 9, 9, 9 and the engaging pins 8, 8, 8 of the rotary shafts 7, 7, 7 are not fitted to each other, and the engaging pins 8, 8, 8 are engaged pins 8, 8, 8 in a state where the rotary shafts 9, 9, 9 are pressed in the axial direction (arrow b direction) against the urging force (arrow b ′ direction) of the ridge 10. The cylindrical side surfaces are in pressure contact with the tip surfaces 9 ', 9', 9 'of the rotary shafts 9, 9, 9. FIG. 9 shows the relationship between the rotary shafts 9, 9, 9 and the engaging pins 8, 8, 8 of the rotary shafts 7, 7, 7 in this state.

  From this state, when the drive switch is turned on, the sliding rotary shafts 9, 9, and 9 simultaneously rotate in one direction (arrow a direction) while maintaining a constant angle. In particular, since the sliding rotary shafts 9 and 9 corresponding to the rotary shafts 7 and 7 are driven by the same timing belt 21, the male and female engaging grooves 11 ′ and 11 ′ maintain the same angle (parallel state). Rotate in the direction of arrow a at the same timing. When each of the rotary shafts 9, 9, 9 is rotated in the direction of arrow a, when the rotary shafts 9, 9, 9 are rotated by a predetermined angle, the male and female engaging grooves 11 ', 11', 11 ' Since the engaging pins 8, 8, 8 of the rotary shafts 7, 7 have the same angle, the male and female engaging grooves 11 ′, 11 ′, 11 ′ of the rotary shafts 9, 9, 9 are at that time. The engaging pins 8, 8, and 8 of the rotating shafts 7, 7, and 7 are automatically engaged with each other (the state shown in FIG. 8B). That is, when the male and female engaging grooves 11 ′, 11 ′, 11 ′ and the engaging pins 8, 8, 8 are at the same angle, the sliding rotary shafts 9, 9, 9 slides in the direction of the arrow b ′, and the male and female engaging grooves 11 ′, 11 ′, 11 ′ and the engaging pins 8, 8, 8 are fitted.

After that, the male and female engaging grooves 11 ′ and 11 ′ of the rice feed rollers 6 and 6 rotate while maintaining the same angle with each other, and are stirred with the engaging pins 8 and 8 of the rice feed rollers 6 and 6. Since the blades 24 are in a fixed positional relationship with each other, the stirring blades 24 of the rice feed rollers 6 and 6 have a phase relationship that does not interfere with each other as shown in FIG. 1, and rotate at the same speed while maintaining this phase relationship. . Therefore, the stirring blades 24 can be driven to rotate at the same timing (same phase) without interference.
