A magnetic levitation bait casting device for reducing bait pollution and its application method

Abstract

The invention discloses a magnetic levitation bait casting device for reducing bait pollution and a method for using the same, comprising an electromagnetic control device and a bait box, wherein the electromagnetic control device is fixed above the water surface through a support frame, and a bait box is connected below the electromagnetic control device. The inner interval of the electromagnetic control device is provided with a plurality of electromagnetic coils, a permanent magnet is arranged between every two electromagnetic coils, and the center of the electromagnetic control device is provided with a geomagnetic sensor, a central control unit and a power supply connected in series; the bait box The top of the tank is provided with a top plate, the outer wall is provided with a screen door, and the inside is provided with a fish driving signal device, and the bottom plate of the bait box is slidably connected with the support frame. The invention can realize the effective recovery of residual bait with different specific gravity, avoid the deposition and decay of residual bait, not only improve the utilization rate of resources, but also reduce the pollution of bait to the water body and bottom mud of the breeding pond, improve the breeding environment, and ensure the safety and security of aquatic products. Human health, suitable for promotion and use.

Description

technical field [0001] The invention relates to a bait throwing device and a use method thereof, in particular to a magnetic levitation bait thrower and a use method thereof for reducing bait pollution. Background technique [0002] With the rapid development of the aquaculture industry, it is very common to adopt the method of aquaculture ponds to store aquatic products. During the aquaculture process, a large amount of bait is required. At present, the aquaculture industry in my country generally adopts manual or automatic bait feeding machines for throwing and loose feeding, and the bait feeding efficiency is low and the cost is high. More importantly, inappropriate feeding methods lead to a large surplus of bait, which will not only cause unnecessary waste of resources, but also deposit and rot the remaining bait, causing water quality and sediment pollution in the breeding pond, thus affecting aquatic products and even the physiological health of the human body . At t...

AI Technical Summary

Problems solved by technology

However, this patent does not have the function of recovering the residual bait, and cannot solve the problem of the pollution of the breeding pond caused by the residual bait

There is also an invention patent net cage bait feeding device [application number CN201910013750.5], which uses a net cage and a feeding pipe to drive a stirring device connected to the surface of the rotating shaft under the action of the motor to stir the bait in the bait box, improving the efficiency of bait feeding , but the problem of bait recovery is still not considered

[0004] At the same time, according to the search of existing patents, there is no patent that can realize the simultaneous recovery of light bait and heavy bait with different specific gravity
