2. Description of the Related Art In a grain dryer for drying and drying a grain through air, exhaust air passing through a layer to be dried and discharged from an air outlet includes straw chips, grain husks, spikelets, mushrooms, mud or dust. Contains a lot of dust. In addition, the grain dryer may be provided with a dust collector that removes dust mixed with the grain to be dried. Is discharged.

Conventionally, in general farmers, the exhaust port of a grain dryer is guided outside by a duct, and the exhaust air containing dust is discharged from the exhaust port as it is to the outside. Further, in a grain drying facility, the actual situation is that dust discharged together with the exhaust air is collected by a wet dust collector or a dry dust collection chamber.

[0004]

By the way, even when the exhaust air discharged from the exhaust port of the grain dryer is guided outside by a duct and discharged, it is unavoidable that the surrounding environment is deteriorated due to dust. The demand for dust collectors used in conjunction with grain dryers is also increasing among general farmers, and various types of wet or dry dust collectors have been developed and put to practical use in order to meet the demand.

[0005] For example, a conventional wet cyclone type dust collector is one example of such a wet cyclone type dust collector. The wet cyclone type dust collector is composed of a swirl part for exhaust air, a cyclone part communicating with the swirl part, and a wet type dust collector. It requires a fairly large installation space.

On the other hand, since the use period of the grain dryer is limited to the harvesting season of the grain, the use period of the dust collector for the grain dryer is naturally limited to this. The occupied dust collector is an obstacle during periods of non-use, and in particular, general farmers are demanding a dust collector that can be kept compact when not in use.

In order to meet the demand, the present invention provides a dust collector for a grain dryer which can be stored in a small size in a non-use mode, even if it occupies a large installation space in a use mode. The purpose is to provide.
