You may. When the stopper 35 is removed and the rice washing tank 3 is detached from the machine casing 2, the suction pipe 8 (the third portion 8c) and the drain pipe 27 are flexible and flexible pipes. Even if the pipe 27 remains connected, the rice washing tank 3 can be moved from the position where the rice washing tank 3 is attached to the machine frame 2, and the presence of the suction pipe 8 and the drain pipe 27 does not hinder the attachment and detachment of the rice washing tank 3.

Further, since the suction pipe 8 and the drain pipe 27 which are detachable from the rice washing tank 3 are flexible pipes, the suction pipe 8 and the drain pipe 27 can be easily attached and detached. The drain port 40 and the drain box 28 are located at substantially the same height, and the drain pipe is arranged so that its longitudinal direction is substantially horizontal, whereas the third portion 8c of the suction pipe 8 is elongated. It is arranged so that the direction is oriented almost vertically, and the intake port 39,
The connection portion of the third portion 8c to the second portion 8b exists at a position vertically separated from the connection portion. For this reason, the third of the suction pipe 8
The length of the portion 8c is the same as that of the intake port 39 and the second portion of the third portion 8c.
It is longer than when the connection to the part is set at the same height. Since the third portion 8c of the suction tube 8 has a certain length, when the rice washing tank 3 is attached or detached,
It is easy to move the rice washing tub while the third portion 8c is connected to the rice washing tub 3, and the attaching and detaching work becomes easy.

A part of the third part 8c and a part of the second part 8b of the suction pipe 8 also serves as an overflow pipe for discharging surplus water from the rice washing tank 3 to the outside of the machine. That is, the suction pipe third portion 8 connected to the upper part of the side wall of the rice washing tank 3
When the water level in the rice washing tank 3 rises from the position c, the surplus water is supplied to the suction pipe third portion 8 which is also an overflow pipe.
c and into the drain box 28 through the lower part of the second portion 8b, and is discharged outside the machine.

Here, since the suction pipe third portion 8c extends downward from the suction port 39 which is also the overflow port, overflow water easily flows. That is, since the third portion 8c is connected to the second portion 8b at a position lower than the intake port 39, overflow water easily flows. When the suction pipe 8 is used for suction, the suction pipe 8 connected to the drainage system needs to be cut off from the drainage system (the drain box 28 and the drain pipe 27).
Is provided with a shutoff valve (not shown) for shutting off the suction pipe 8 from the drainage system. The shutoff valve may be a valve that is controlled by a control unit so as to shut off between the suction pipe 8 and the drain box 28 when the suction device 9 is operated, or may be a suction pipe 8 from the drain box 28 side during suction. The suction valve 8 may move upward by gravity when it is not suctioned, and may be moved downward by gravity to communicate between the suction pipe 8 and the drain box 28.

It should be noted that the suction pipe 8 is not connected to the drain box 28 but directly from the top plate 17 to the suction port 3 in the side wall of the rice washing tank 3.
9 may be connected. As described above, since the rice supply pipe 7 and the suction pipe 8 are connected to the rice washing tank, when the suction device 9 is operated, the shutoff valve shuts off the suction pipe 8 and the drainage system, and the suction pipe 8
, The inside of the sealed rice washing tank 3 can be set to a negative pressure. Then, when the inside of the rice washing tank 3 is made to have a negative pressure, the inside of the rice supply pipe 7 also has a negative pressure.
The rice inside is sucked, and the rice is sucked and transported into the rice washing tank 3. That is, the rice supply pipe 7, the suction pipe 8, and the suction device 9
It constitutes a rice transport mechanism. The air sucked by the suction device 9 is returned into the receiving member 6.

The rice is conveyed by suction by creating an air flow in a closed path composed of the rice supply pipe 7, the suction pipe 8 and the rice washing tank 3, and then operating the metering machine 5 to rotate the drum 26,
Every time the drum 26 rotates, the rice falling into the receiving member 6 is sent into the rice washing tank 3 by the air flow, and the rice is washed through the rice inlet 30 into the rice washing tank 3.
Released into When the operation of the suction device 9 is stopped after the metering machine 5 discharges and transports the required amount of rice, the required amount of rice is stored in the rice washing tank 3. Rice supplied from the rice inlet 30 into the rice washing tank 3 is discharged into the rice washing tank 3 through the guide portion 45. This guide part 45
The guide portion 45 guides the rice dropped and discharged from the rice input port 30 while guiding the rice to reduce the momentum of the rice discharge.
As a result, it is possible to reduce the possibility that the rice discharged with a large momentum collides with the rice washing tank 3 and is pulverized into waste rice.

When the rice is supplied into the rice washing tank 3, water is supplied into the rice washing tank 3 by a water supply means, and the rice is washed by the rotation of the stirring rod 18. As shown in FIGS. 6 and 7, the stirring rod 18 is made of a plurality of solid or hollow rods, and the first to fourth stirring rods 18A, 18B, 18C, and 18D are connected to the rotating shaft 16.

It is provided in a wide range from the top to the bottom. The fourth stirring rod 18D is provided at a lower portion of the rotating shaft 16 with a phase shifted by 180 ° from the second stirring rod 18B.

The third stirring rod 18C is the longest in the radial direction,
Then, the second stirring rod 18B, the first stirring A, the fourth stirring rod 1
8D is formed to be short in the radial direction in this order. The upper and lower ends of the first to third stirring rods 18A, 18B, 18C have horizontal portions bent in the radial direction so as to be fixed to the rotating shaft 16. Regarding the fourth stirring rod 18D, the upper end is fixed to the rotating shaft 16, but the lower end is extended near the upper part of the rice discharge valve 15 and is a free end. Thus, the phase around the rotation axis 16 is shifted,
Further, by providing a plurality of agitators having different vertical positions, lengths, and radial lengths, the rice in the rice washing tank 3 can be uniformly stirred.

The third stirring rod 18C, which is the longest in the radial direction,
Is larger at the radially outer end than at the fixed end to the rotating shaft 16,
It is bent in the direction opposite to the rotation direction of the rotation shaft 16 indicated by the arrow in FIG. By bending in this way, the horizontal part of the stirring rod is bent, and the horizontal part of the stirring rod is more likely to prevent rice from remaining in the horizontal part and generating residual rice than the straight part. it can.
Note that the present invention is not limited to the above embodiment.
