Recyclable lifting type bait casting device capable of reducing bait pollution and using method

Abstract

The invention discloses a recyclable lifting type bait casting device capable of reducing bait pollution and a using method. The recyclable lifting type bait casting device comprises a bait box and anelectric lifting device, the bottom of the bait box is connected with the electric lifting device, a gauze door is arranged in the middle of the bait box, a bottom plate is arranged at the bottom ofthe bait box, the gauze door is in sliding connection with a sliding rail on the bait box, an upper inner net is arranged at the top of the gauze door, and a lower inner net is arranged at the bottom;and the electric lifting device comprises a multi-stage lifting rod, the bottom of the lifting rod is connected with a lifting controller, and the bait box can be controlled by the electric lifting device to achieve the two states of sinking into water and floating out of the water surface. The recyclable lifting type bait casting device is simple and easy to implement, lifting is easy to control, and use cost is saved; separation of light and heavy baits and recovery of residual baits can be realized, so that the utilization rate of resources is increased, and meanwhile, the environmental pollution of a culture pond is reduced.

Description

technical field [0001] The invention relates to a bait throwing device and a use method thereof, in particular to a recyclable lift-type bait thrower and a use method for reducing bait pollution. Background technique [0002] China is a big country in aquaculture and aquatic products export, and there is a great demand for feeding aquatic products. At present, the feeding methods of aquaculture in my country are mainly artificial or small-scale automatic feeding machines. These existing feeding methods are difficult to achieve efficient use of bait. At the same time, unused bait will float to the breeding ground. Around the pond, or sink in the bottom of the culture pond, causing a certain degree of environmental pollution to the culture pond. On the other hand, since the density of bait is also different, how to realize the separation and recovery of light and heavy bait is also a difficult problem to be overcome. [0003] The current search finds that existing bait feedin...

AI Technical Summary

Problems solved by technology

[0003] The current search finds that existing bait feeding equipment has obtained patent authorization, but most of them adopt the loose casting mode, such as the device disclosed in the Chinese patent application number CN105994095A, which uses a motor and a throwing tray for feeding, but this type of patent fails to realize the recovery of residual bait Recycling can't solve the problem that the residual bait causes the pollution of the breeding pond; another example is the bait throwing device disclosed in CN109619011A, which uses a net cage and a feeding pipe to drive the stirring device connected to the surface of the rotating shaft under the action of the motor to stir the bait in the bait box. , to improve the efficiency of bait delivery, but the problem of bait recovery is still not considered
