Magnetic levitation bait casting device capable of reducing bait pollution and using method thereof

Abstract

The invention discloses a magnetic levitation bait casting device capable of reducing bait pollution and a using method thereof. The magnetic levitation bait casting device comprises an electromagnetic control device and a bait box, wherein the electromagnetic control device is fixed above the water surface through a supporting frame, the lower portion of the electromagnetic control device is connected with the bait box, and a plurality of electromagnetic coils are arranged in the electromagnetic control device at intervals; an electromagnet is arranged between every two electromagnetic coils,and a geomagnetic sensor, a central control unit and a power supply which are connected in series are arranged in the center of the electromagnetic control device; and a top plate is arranged at thetop of the bait box, a gauze door is arranged on the outer side wall of the bait box, a fish expelling annunciator is arranged in the bait box, and a bottom plate of the bait box is slidably connectedwith the supporting frame. According to the magnetic levitation bait casting device, residual baits with different specific gravities can be effectively recycled, deposition and rotting of the residual baits are avoided, the utilization rate of resources is increased, pollution of the baits to water and bottom mud of a culture pond can be reduced, the culture environment is improved, the safety of aquatic products and human health are guaranteed, and the magnetic levitation bait casting device is suitable for application and popularization.

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...

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
