Abstract

The present invention proposes an automatic bait feeding and metering device for deep-water net cages, comprising: a housing, with feed ports and discharge ports respectively arranged at the upper and lower ends; a central rotating shaft, vertically arranged in the housing; a rotating wheel , installed horizontally on the central rotating shaft, and rotates with the rotation of the central rotating shaft; the torque measuring device is used to measure the torque of the central rotating shaft; the driving device is connected with the central rotating shaft and is used to drive the central rotating shaft to rotate; the rotational speed measuring device, fixed on the output shaft of the driving device. The present invention has simple structure, fewer measurement influencing factors, and accurate measurement; good reliability, and can realize real-time feedback and control; the device does not involve the influence of gravity changes such as mechanical vibration during the conveying process of pellet feed, and avoids isostatic measurement of weighing error effects.

Description

technical field [0001] The invention relates to a metering device, in particular to an automatic bait feeding metering device for deep-water cage culture. It belongs to the field of deep-water cage culture. Background technique [0002] At present, my country's deep-water cage culture generally uses pellet feed, which is basically manually transported and fed, which increases labor intensity and reduces work efficiency. There are differences in the density and volume of different types of feed particles. During the feeding process, the feed density in the rotary feeder changes continuously, and the feed delivery volume also changes synchronously. Since the metering system takes feed volume flow as the metering result, the bait feeding system has the disadvantages of inaccurate feed metering and large errors. According to the test measurement, the feed feeding error is about ±10%. Inaccurate measurement not only affects the accuracy and efficiency of feeding, but more impo...
