Then, a single cleaning hose (46) having a suction cleaning port at the tip is carried to the destination, and one of the connection ports (43a) to (43d) in the vicinity thereof is carried.
The hose (46) is connected to the collecting tank (44) so that dust sucked by a vacuum suction force from the cleaner (39) of the hose (46) is collected in the collecting tank (44).

When the dust collected in the collecting tank (44) is full, the rice husk discharge duct (48) of the turbo rice husk discharge fan (47) for discharging and conveying the rice husk of the rice huller (27). The rice husk discharge port (50) facing the feed end of the rice husk discharge conveyor (49) of the rice huller (27) and the discharge duct (48) are connected by a connection duct (51). The duct (5)
1) An air-lock type rice husk discharge valve (52) is interposed therein, and a discharge port (54) having an air-lock type tank discharge valve (53) of the collecting tank (44) is detachable or fixed. The connection duct (51) is communicatively connected to the inlet side of a discharge valve (52) via a dust discharge duct (55). In addition, a dust switching valve (56) is provided between the junction of the discharge duct (48) to which the connection duct (51) is connected and the rice husk storage (38), and the dust exhaust equipment (36) or the dust collecting chamber is provided. The switching valve (53) is connected via a dust collection duct (58) to a wet dust collection device (57) that contains water, and is generated during the removal operation by the removal roll (59) of the huller (27) during normal times. The rice husk to be conveyed to the rice husk storage (38) by the wind generated by the discharge fan (47), and when the collecting tank (44) is full of dust, the dust is collected by the wind generated by the discharge fan (47) (57). It is configured to be conveyed to.

Further, as shown in FIG. 4, a hulling operation switch (60) which is turned on during the hulling operation, and a tank capacity sensor (61) for detecting the amount of dust in the collecting tank (44) are provided. The switch (60) and the capacity sensor (61) are input-connected to the controller (62), and the huller (27), the discharge conveyor (49), the discharge fan (47), the rice husk discharge valve (52), and the tank discharge. The controller (62) is connected to the valve (53) and the exhaust switching valve (56) for output, and the collecting tank (44) is connected.
It is configured to automatically discharge dust by effectively utilizing a rice husk discharge fan (47) when the dust is full.

As shown in the flowchart of FIG.
During the hulling operation, the tank discharge valve (53)
Is closed and the rice husk discharge conveyor (49) and fan (4
7) By driving the rice husk discharge valve (52) and switching the switching valve (56) to the rice hull storage (38) side, the rice husks generated during the screwing operation by the screw roll (59) are discharged by the discharge fan. It is transported to the rice husk storage (38) by the wind force from (47). Also, when the sensor (61) detects the fullness of dust in the collecting tank (44) during the hulling operation or after the hulling operation, the hulling operation is stopped during the hulling operation, and the hulling discharge conveyor ( 49) is stopped and the tank discharge valve (5
3) is opened, and the switching valve (56) is switched to the dust collecting device (57) side, and the dust in the tank (44) is collected until the dust in the collecting tank (44) becomes a certain amount or less. ).

[0014] Thus, the dust collection system of the collecting tank (44) and the cleaner (39) can be simply added to the air blowing system of the discharge fan (47) for transporting the rice husks generated by the normal huller (27). With such a configuration, it is possible to clean labor-saving facilities after work is completed or during off-season.

FIGS. 6 to 8 show the collecting tank (44).
When the dust is full, a dedicated exhaust fan (4
7a) shows a configuration in which a dust exhaust fan (47
a) and a dust collecting device (57), a dedicated dust discharging duct (48a) is provided with a discharge port (54) having a tank discharge valve (53) of the collecting tank (44), and a dust discharging duct (55). ), And a dust switch (63), which is turned on during the dust discharging operation of the dust collecting tank (44), and a capacity sensor (61) of the tank (44) are connected to the controller (62). The controller (62) is connected to the cleaner (39), the dust discharge fan (47a), and the tank discharge valve (53).

As shown in FIG. 8, when the cleaner (39) is driven, dust from various parts such as the storage bin (9) is sucked into the collecting tank (44) and the tank (44) is filled with dust. Is detected by the sensor (61), the driving of the cleaner (39) is stopped, the exhaust fan (47a) is driven, and the exhaust valve (53) is opened.
While the dust in the tank (44) is conveyed to the dust collecting device (57), when the dust in the tank (44) is reduced to a certain amount or less, the operation of the dust exhaust fan (47a) is stopped, and the exhaust valve (5) is stopped.
3) is closed to stop the dust discharging operation.

Thus, the storage bin (9) and the silo (2)
0) Dust such as dust and scattered grains generated around the area is suctioned by the collecting tank (44) with the hose (46) for cleaning, and when the collecting tank (44) is full, dust is manually removed each time. Without discharging the dust, the dust in the tank (44) is automatically discharged until the dust becomes a certain amount or less, so that the cleaning operation can be performed efficiently.
