A feeder and a feeding method protecting feedstuff from moisture

摘要

A feeder and a feeding method that can prevent feedstuff from moisture, comprises a base (1), a feedstuff box (31) with a feedstuff discharging port which can be driven to rotate; especially the said feedstuff box (31) comprises a flap (32) that can cover the said feedstuff discharging port. The said flap cover can be opened automatically when the feedstuff box rotates to the position that its discharge port is facing downwards, i.e. it is in the discharging status, and will be kept closed when the said discharge port facing upwards, i.e. it is not in the said discharging status. Said feedstuff port flap (32) is assembled onto the feedstuff box (31) by way of a shaft (37) that is parallel to the rotating axial of said feedstuff box, with a counterweight (35) assembled on its heavier side. Inside said feedstuff box (31) comprises at least a rim (36) on its sidewall, so feedstuff will strike with the rim to eliminate agglomeration when rotating. Especially for aquatic fishes feeding, the said feeder or feeding method can prevent the fish feedstuff located over fish tanks from agglomeration, which ensuring the automatic or accurate discharging of the feedstuff. The above measures are low cost and easy to take.
