Timed and quantitative feeding device for aquaculture

The invention discloses a timed and quantitative feeding device for aquaculture. The timed and quantitative feeding device comprises a basic cylinder, a connecting cylinder and a storage hopper; the storage hopper is fixedly mounted at the top end of the basic cylinder; the connecting cylinder is rotatably mounted on one side of the outer wall of a quantifying device; a discharging device is rotatably mounted at the bottom end of the basic cylinder; a timing device is fixedly mounted at the position, corresponding to the connecting cylinder, on the outer wall of the basic cylinder, and the quantifying device with a quantifying function is slidably mounted in the connecting cylinder. The quantifying device is adjusted by pulling a pull handle to quantify guided-out feed, the feed in a sliding groove is guided out at regular time through the timing device by starting a variable-speed motor, and a discharging motor is started to drive the discharging device, so that the feed in a discharging barrel is uniformly
