Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an automatic feeding machine for sea cucumber seedling cultivation. Background Art

[0002] As a kind of high-protein, low-fat precious aquatic product, sea cucumber has high value and demand in the market. With the continuous improvement of people's pursuit of healthy food and the development and utilization of marine resources, sea cucumber breeding industry has gradually emerged and developed rapidly. With the expansion of sea cucumber breeding scale, the problem of feeding sea cucumber seedling bait has gradually attracted people's attention. At present, in the sea cucumber breeding process, the method of artificial feeding is mostly adopted, but artificial feeding cannot guarantee the uniformity of feeding, and the labor intensity is large, the efficiency is low, and even the bait is wasted and the breeding water quality is polluted, which affects the development of sea cucumber seedlings. Therefore, sea cucumber seedling feeding machine comes into being. The existing sea cucumber seedling feeding machine is mainly for pond breeding and cage breeding of sea cucumber. This type of sea cucumber seedling feeding machine usually includes a feeding device, a stirring device, a water conveying device and a throwing device, which can do reciprocating motion along the guide rail above several ponds or several cages, and the bait is evenly thrown in several ponds or several cages. When this type of sea cucumber seedling feeding machine is in use, a certain amount of bait must first be input into the feeding device, and then the sea cucumber seedling feeding machine is controlled to reciprocate along the guide rail above several ponds or several cages. At this time, the feeding device inputs the bait into the stirring device, and at the same time the water supply device inputs water into the stirring device. The stirring device stirs the mixture of bait and water, thereby diluting the bait. After the dilution of the bait is completed, the stirring device inputs the diluted bait into the spreading device, and the spreading device evenly spreads the diluted bait into several ponds or several cages.

[0003] The feeding device, stirring device, water delivery device and throwing device in this type of sea cucumber seedling feeding machine are large and independent of each other, resulting in a large total volume of this type of sea cucumber seedling feeding machine, which is not light and flexible enough. Some small automatic feeding machines used in domestic factory farming are mostly used to feed granular baits and other solid types of baits, which are not suitable for feeding sea cucumber seedlings. Therefore, it is urgent to develop a light and flexible sea cucumber seedling feeding machine. Summary of the invention

The present invention can input bait into the mixing barrel body in a quantitative manner by controlling the start and stop of the Jiaolong motor.

[0016] 3. In the present invention, a water delivery device is also designed. When in use, water must first be delivered into the water storage mechanism through the water inlet of the water storage mechanism. When water needs to be delivered into the mixing barrel, the water pump is controlled to enter the working state, and the water in the water storage mechanism will be delivered into the mixing barrel through the first water pipe under the action of the water pump.

[0017] 4. In the present invention, a moving device is also designed, which can drive the pulley to reciprocate on the guide rail by controlling the driving motor to enter the working state. Since the mixing barrel body is installed on the pulley through the connecting frame, when the pulley reciprocates on the guide rail, the integrated bait mixing and spreading device will also reciprocate along the guide rail, thereby evenly spreading the material in the mixing barrel body in the pond or cage.

[0018] Based on the above reasons, the present invention can be widely promoted in fields such as aquaculture. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A third sealing ring is provided between the front end cover and the side wall of the sleeve and between the rear end cover and the side wall of the sleeve to prevent the bait in the feeding sleeve 2022 from overflowing from the feeding sleeve 2022 through the gap between the front end cover and the side wall of the sleeve and the gap between the rear end cover and the side wall of the sleeve.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, the material box 201 is a trumpet-shaped structure with a large opening facing upward and a small opening facing downward; the large opening of the material box 201 is the material inlet of the material box 201, and the small opening of the material box 201 is the material outlet of the material box 201.

[0038] When using the quantitative feeding device 2, a certain amount of bait must first be input into the material box 201 through the material box feed port. Under the action of gravity, the bait in the material box 201 will be input into the feeding sleeve 2022 along the side wall of the material box 201 through the material box discharge port and the sleeve feed port in sequence. The spiral blade 2021 in the feeding sleeve 2022 rotates around its axis under the drive of the Jiaolong motor 2023, thereby pushing the bait in the feeding sleeve 2022 to the sleeve discharge port, and the bait at the sleeve discharge port is input into the mixing barrel body 402 through the mixing barrel feed port. This embodiment can input bait into the mixing barrel body 402 in a quantitative manner by controlling the start and stop of the Jiaolong motor 2023.

The water in the water storage mechanism will be input into the mixing barrel body 402 through the first water pipe 303 under the action of the water pump 304. After a certain amount of water is input into the mixing barrel body 402, the impeller motor 4043 is controlled to enter the working state. The impeller can be driven by the impeller motor 4043 to stir the mixture of bait and water in the mixing barrel body 402, thereby diluting the bait in the mixing barrel body 402.

[0044] In this embodiment, a first circular groove is opened on the upper surface of the mixing barrel cover 403 at a position corresponding to the lower end of the mixing barrel body 402, and a first sealing ring is filled in the first circular groove. When the mixing barrel cover 403 is closed on the opening at the lower end of the mixing barrel body 402, the first sealing ring fits with the lower end of the mixing barrel body 402.

[0045] By setting a first sealing ring between the mixing barrel body 402 and the mixing barrel cover 403, when the mixing barrel cover 403 covers the opening at the lower end of the mixing barrel body 402, the material in the mixing barrel body 402 will not overflow from the mixing barrel body 402 through the gap between the mixing barrel body 402 and the mixing barrel cover 403, thereby avoiding waste of bait.
