[0002]

The conventional paddy dryer dries by storing paddy in a dryer to which hot air has been sent and circulating the paddy. Then, the hot air sent to the dryer is discharged together with dust such as straw chips from a dust outlet located at an upper portion of the dryer and an exhaust outlet located at a lower portion of the dryer. If such dust is discharged to the outside as it is, it becomes harmful, and it is necessary to use a dust collector. Conventionally, as shown in FIG. 4, this type of dust collector collides hot air A from an exhaust port (not shown) of a dryer through a discharge tube 1A of an exhaust duct 1 onto a water surface 3 of a water tank 2 to remove dust. Captured by water surface 3, while
The hot air B from a dust outlet (not shown) of the dryer collides with the water surface 3 of the water tank 2 through the discharge tube 4A of the air discharge duct 4 so that dust is captured by the water surface 3. A and B are discharged through the filter 5 and are further trapped in the water tank 2 and discarded at the bottom.
Once the discharge cylinders 1A and 4A are lifted, dust C on the bottom of the water tank 2 is removed.
Was scrapped and discarded.

[0003] In such a conventional dust collector, although dust can be collected without using electricity or the like, there is a problem that the filter 5 is clogged when used for a long time. Further, in this type of dust collector, the dust C collected in the water tank 2 must be lifted and moved after lifting the discharge cylinders 1A and 4A, and then the dust C at the bottom of the water tank 2 must be scooped up. there were.

Accordingly, an object of the present invention is to improve dust collection efficiency in a dust collector that catches dust by colliding wind with the water surface. Another object of the present invention is to provide a dust collector that can easily collect captured dust.
