Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a catamaran-mounted feeding device. Background Technology

[0002] Currently, in aquaculture operations, feeding mainly relies on two methods: one is manual throwing with a ladle or bucket, which is labor-intensive, inefficient, and results in poor uniformity of feeding, easily leading to overfeeding or underfeeding in certain areas, affecting aquaculture efficiency; the other is using a simple feeding device mounted on a small, single-hulled boat, but single-hulled boats have weak resistance to wind and waves when traveling on the water, and the hull is prone to tilting and swaying, causing the feeding device to shake violently, scattering the material randomly, and making it difficult to accurately control the feeding position and range.

[0003] While existing shipboard feeding devices have achieved mechanized feeding, they generally suffer from the following problems: First, the feeding angle and output are fixed, making it impossible to flexibly adjust according to different water areas, wind directions, or feeding distances, resulting in poor adaptability; second, the storage and feeding structures are complex, inconvenient to install and disassemble, and prone to material blockage; third, the lack of effective material acceleration and conveying structures leads to short feeding distances and small scattering ranges. Furthermore, existing devices are mostly integrated designs with low modularity, making it difficult to quickly adjust or maintain them according to actual feeding needs.

[0004] Therefore, it is necessary to develop a catamaran-mounted feeding device that is stable, has controllable feeding, adjustable angle, and is easy to assemble and disassemble, in order to solve the above problems. Summary of the Invention

[0005] This invention provides a catamaran-borne feeding device, which aims to solve the problems of poor stability, uncontrollable feeding, and complex structure of existing feeding methods.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1

[0036] like Figures 1 to 7 As shown, a specific embodiment of the catamaran-borne feeding device of the present invention includes:

[0037] The catamaran carrier consists of two individual boats 1, a connecting frame 2, and a hull fixing plate 3. The connecting frame 2 is placed above the two individual boats 1, and the hull fixing plate 3 is fixedly connected to the upper end of the connecting frame 2. The outer frame 4 is fixedly installed on the upper end of the hull fixing plate 3 to support and fix the feeding components.

[0038] The storage device 11 is located on the top of the outer frame 4, and its lower end is provided with a discharge port; the pull plate 12 is horizontally located at the discharge port and can be pulled back and forth in the horizontal direction; the operator can manually pull the pull plate 12 to control the opening area of ​​the discharge port, thereby realizing the opening and closing of the discharge port and adjusting the discharge amount of material.

[0039] Below the pull-out plate 12 is a conveying device 9, which is used to receive the material falling from the storage device 11 and convey it forward. The conveying device 9 is in the shape of a guide channel, and a high baffle 91 and a low baffle 92 are respectively provided on both sides. The height of the high baffle 91 is higher than that of the low baffle 92. The high baffle 91 can play a role in wind protection during the material falling process, preventing the material from being blown away by the wind. The low baffle 92 is lower in height, making it easier to observe the material flow in the conveying device 9.

[0040] The conveying support frame 6 is vertically fixed inside the outer frame 4, and a rotating shaft 8 is horizontally installed on the conveying support frame 6; a round hole is opened at the end of the conveying device 9, which is rotatably connected to the rotating shaft 8 through the round hole, so that the conveying device 9 can swing up and down around the rotating shaft 8 to achieve angle adjustment.

[0041] A support connector 15 is installed at the bottom of the conveying device 9. The support connector 15 includes a first connecting rod 151 and a second connecting rod 152 that are rotatably connected. One end of the first connecting rod 151 is fixedly connected to the support 93 at the bottom of the conveying device 9 by bolts and nuts. One end of the second connecting rod 152 is fixedly connected to the support plate 17 by bolts and nuts. The support plate 17 is vertically installed on the support plate 7, which is fixedly installed on the conveying support frame 6 and located below the rotating shaft 8. When it is necessary to adjust the angle of the conveying device 9, the operator can manually loosen the bolts and nuts at the connection between the first connecting rod 151 and the second connecting rod 152, rotate the conveying device 9 around the rotating shaft 8 to the required angle, and then tighten the bolts and nuts. The first connecting rod 151 and the second connecting rod 152 then form a rigid support, keeping the conveying device 9 at that angle position.

[0042] The motor 5 is fixedly installed on the outer frame 4; the centrifugal air conveying device 18 is a centrifugal fan structure, including a volute 181, an impeller 185, an air inlet 183 and an air outlet 182; the impeller 185 is set inside the volute 181 and is fixedly connected to the output shaft 51 of the motor 5 through the shaft connector 184; after the motor 5 is powered on, it drives the impeller 185 to rotate at high speed, generating airflow.

[0043] A flow guide device 13 is provided below the front end (the end away from the rotating shaft 8) of the conveying device 9; the flow guide device 13 is funnel-shaped with a large opening at the upper end for receiving materials sliding down from the conveying device 9; its lower outlet is small and is connected to the material throwing guide device 14; the material is gathered by the flow guide device 13 and enters the material throwing guide device 14.

[0044] The material throwing guide device 14 is a pipe, one end of which is connected to the air outlet 182 of the centrifugal pneumatic conveying device 18, and the other end extends to the outside of one side of the monohull 1. The outlet end of the material throwing guide device 14 has a flat nozzle structure, which can guide the direction of material throwing. Under the push of the airflow, the material enters the material throwing guide device 14 through the guide device 13 and is finally thrown outward from the flat nozzle outlet.

[0045] The storage battery 10 is located at the rear of the material throwing guide device 14 and is connected to the motor 5 via wires to provide power to the motor 5.

[0046] The working principle of this invention is as follows: The operator loads the material to be distributed (such as fish food or feed) into the storage device 11 and manually pulls the pull plate 12 to adjust the opening of the discharge port according to the required amount of material. Under the action of gravity, the material falls from the discharge port onto the conveying device 9 and slides forward along the slide of the conveying device 9. According to the requirements of the feeding distance and the falling speed, the tilt angle of the conveying device 9 can be adjusted by loosening the bolts and nuts of the support connector 15 and then tightening them again. The material falls into the funnel-shaped guide device 13 at the front end of the conveying device 9 and enters the material dispersing guide device 14. The motor 5 drives the impeller 185 to rotate at high speed to generate airflow. Under the action of the airflow, the material is accelerated and blown out from the material dispersing guide device 14, enters the material dispersing guide device 14 through the air outlet 182, and is finally evenly dispersed onto the water surface from the flat nozzle outlet.
