Abstract

The invention provides an automatic bait casting metering device of an offshore fish cage. The device comprises a shell, a center rotary shaft, a rotary wheel, a torque measuring device, a drive device and a rotation speed measuring device, wherein the upper end and the lower end of the shell are provided with a feeding inlet and a discharge outlet respectively, the center rotary shaft is vertically arranged in the shell, the rotary wheel is horizontally installed on the center rotary shaft and can rotate along with rotation of the center rotary shaft, the torque measuring device is used for measuring the torque of the center rotary shaft, the drive device is connected with the center rotary shaft and is used for driving the center rotary shaft to rotate, and the rotation speed measuring device is fixed to an output shaft of the drive device. The automatic bait casting metering device is simple in structure, accurate in metering, good in reliability and capable of achieving real-time feedback and control, the metering influencing factors are few, the device cannot be influenced by gravity changes such as mechanical vibration in the conveying process of granulated feed, and accordingly error influences caused by static measurement such as weighing are avoided.

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...
