Pneumatic-transport lobster bait casting machine applied to deep sea net cage

Abstract

The invention discloses a pneumatic-transport lobster bait casting machine applied to a deep sea net cage. The machine comprises the deep sea net cage and a bait casting pipe disposed at the center ofthe top of the cage, wherein a material uniformizing device is disposed on the bottom of the bait casting pipe, the material uniformizing device comprises a casting disk, casting disk baffles are uniformly disposed on the top of the casting disk, a semi-circular shell is disposed at the center of the top of the casting disk, the semi-circular shell is connected to external torque, a bait recoverydevice is installed on the inner wall of the bottom of the deep sea net cage, the bait recovery device comprises a silt storage body, a motor is installed on the side wall of the top of the deep seanet cage, an output shaft of the motor is movably connected to a lead screw by a coupler, the lead screw is sleeved by a lead screw nut sleeve outside, a guide rod is also fixed by welding on the sidewall of the top of the deep sea net cage, and the silt storage body is disposed between a slide sleeve and the lead screw nut sleeve. The machine is characterized by a feed recovery function and goodcleaning effects.

Description

technical field [0001] The invention relates to the technical field of lobster farming, in particular to a lobster bait feeder for pneumatically conveying deep-sea net cages. Background technique [0002] Deep-sea cage culture technology is a stable environment, large water body, and closer to the natural fish and shrimp farming method. The fish and shrimps it breeds are close to wild in shape and meat quality. The current deep-sea cages are equipped with automatic facilities such as automatic baiting, automatic grading and harvesting, automatic counting of fry, and automatic collection of dead fish. [0003] After the existing lobster deep-sea cages are fed, part of the bait sinks into the bottom of the cage after absorbing water and swelling without the lobster eating, and is mixed with the lobster feces, crustacean residues, etc., and cannot be eaten, resulting in waste of bait. Manual direct recovery is not only time-consuming and laborious but also unable to decontamin...

Problems solved by technology

[0003] After the existing lobster deep-sea cages are fed, part of the bait sinks into the bottom of the cage after absorbing water and swelling without the lobster eating, and is mixed with the lobster feces, crustacean residues, etc., and cannot be eaten, resulting in waste of bait. Manual direct recovery is not only time-consuming and laborious but also unable to decontaminate the bait; the existing bait feeding equipment uses the feed volume flow rate as the measurement result of the feeding amount, and the density and volume of different types of feed particles are different, and the feed is dense during the feeding process. different degrees, resulting in inaccurate feed measurement in the feeding system
