According to the above-mentioned proposed structure, the fertilizer which is fed and flows down acts on the net-like filtration part, so that the powdered fertilizer can be efficiently removed. However, if the filtration part becomes clogged. There was a risk that the powdered fertilizer would pass through the filtration unit and clog the inner wall or the like at the downstream. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily recognize a clogging in a filtration unit so that a treatment such as cleaning can be performed at an early stage.

[0004]

A characteristic feature of the present invention is a fertilizing apparatus provided with a feeding device for feeding a granular fertilizer from a fertilizer tank by a set amount and dropping and supplying the fertilizer to a groove generator. A sorting net for receiving the fed-out fertilizer, leaking the powdered fertilizer contained therein, and guiding and dropping the granular fertilizer to the groove generator side, and a container for receiving and storing the powdered fertilizer leaked from the sorting net. , And the drop guide having the sorting net therein is made of a transparent resin.

[0005]

The sorting net acts on a small amount of fertilizer in a state where the flow is large, and the powdered fertilizer is sorted out and leaked into a container. Since the drop guide with the sorting net inside is made of transparent resin, the sorting net can be seen through from the outside, and by monitoring it in a timely manner, the clogging of the sorting net can be quickly recognized and cleaned. And the like.

[0006]

According to the present invention, the sorting net can be easily monitored from the outside of the drop guide and used in an appropriate state without clogging.
