Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to an automatic feeder for sea cucumber seedlings. Background Technology

[0002] Sea cucumbers, as a precious aquatic product high in protein and low in fat, have high market value and demand. With people's increasing pursuit of healthy food and the continuous improvement of marine resource development and utilization, sea cucumber farming has gradually emerged and developed rapidly. As the scale of sea cucumber farming expands, the issue of feeding sea cucumber seedlings has gradually attracted attention. Currently, artificial feeding is mostly used in sea cucumber farming. However, artificial feeding cannot guarantee the uniformity of feeding, is labor-intensive, inefficient, and may even waste feed and pollute the aquaculture water, affecting the development of sea cucumber seedlings. Therefore, sea cucumber seedling feeding machines have emerged. Currently, existing sea cucumber seedling feeding machines are mainly designed for pond and cage culture of sea cucumbers. These machines typically include a feeding device, a stirring device, a water conveying device, and a distributing device. They can reciprocate along a guide rail above several ponds or cages, evenly distributing feed among them. When using this type of sea cucumber seedling feeding machine, a certain amount of feed needs to be fed into the feeding device first. Then, the machine is controlled to move back and forth along the guide rail above several ponds or net cages. At this time, the feeding device feeds the feed into the mixing device, and the water supply device feeds water into the mixing device. The mixing device stirs the mixture of feed and water to dilute the feed. After the feed is diluted, the mixing device feeds the diluted feed into the spreading device, which then evenly spreads the diluted feed into several ponds or net cages.

[0003] The feeding, mixing, water supply, and distributing devices in these types of sea cucumber seedling feeders are large and independent, resulting in a bulky overall size that makes them neither lightweight nor flexible. Furthermore, the smaller automatic feeders used in domestic factory farming are mostly designed for feeding pelleted feed and other solid feeds, and are not suitable for feeding sea cucumber seedlings. Therefore, developing a lightweight and flexible sea cucumber seedling feeder has become an urgent priority. Summary of the Invention

[0004] To address the aforementioned technical problems, an automatic feeder for sea cucumber seedlings is provided. This invention integrates the mixing and dispensing devices of existing sea cucumber seedling feeders, thereby reducing the size of the feeder and making it more portable and flexible. The technical means employed in this invention are as follows:

[0005] An automatic feeder for sea cucumber seedlings includes an integrated feed mixing and dispensing device. This device comprises a mixing tank, a mixing tank cover, an electric cylinder, and a feed mixing and dispensing mechanism. The mixing tank is a cylindrical structure with its axis perpendicular to the horizontal plane and its upper end closed while its lower end is open. A feed inlet is located at the upper end of the mixing tank. The mixing tank cover is located directly below the mixing tank and is detachably fitted onto the lower opening of the mixing tank. The extension and retraction direction of the electric cylinder is aligned with the axial direction of the mixing tank. One end of the electric cylinder is mounted on the mixing tank, and the other end is mounted on the mixing tank cover. The feed mixing and dispensing mechanism includes a pulsator motor and a pulsator. The pulsator motor is mounted on the mixing tank cover, and its output shaft extends upward along the axis of the mixing tank. The pulsator is coaxially mounted on the output shaft of the pulsator motor and located directly above the mixing tank cover. When the mixing tank cover is closed onto the lower opening of the mixing tank, the pulsator is located inside the mixing tank.

[0006] Furthermore, the impeller includes a rotating disk and several stirring and spraying ribs; the rotating disk is coaxially mounted on the output shaft of the impeller motor and located directly above the mixing tank cover; the stirring and spraying ribs are mounted on the upper surface of the rotating disk and extend radially from the axis of the rotating disk to the edge of the rotating disk.

[0007] Furthermore, it also includes a quantitative feeding device, which comprises a hopper and a screw feeding mechanism; the hopper has a hopper inlet at its upper end and a hopper outlet at its lower end; the screw feeding mechanism includes a feeding sleeve, a auger motor, and screw blades; the feeding sleeve is a cylindrical structure with its axis parallel to the horizontal plane and both ends closed, with a sleeve inlet on the upper side wall and a sleeve outlet on the lower side wall, the sleeve inlet being connected to the hopper outlet and the sleeve outlet being connected to the mixing tank inlet; the auger motor is mounted on one end of the feeding sleeve, and the output shaft of the auger motor extends along the axis of the feeding sleeve to the other end of the feeding sleeve; the screw blades are coaxially mounted on the output shaft of the auger motor and located inside the feeding sleeve.

[0008] Furthermore, the material box has a funnel-shaped structure with the larger opening facing upwards and the smaller opening facing downwards; the larger opening of the material box is the material box inlet, and the smaller opening of the material box is the material box outlet.

[0009] Furthermore, it also includes a water conveying device, which includes a water storage mechanism, a water pump, and a first water pipe; the water storage mechanism is installed on the mixing tank body, the upper end of the water storage mechanism has a water inlet, and the lower end of the water storage mechanism has a water outlet; the input end of the water pump is connected to the water outlet of the water storage mechanism, the output end of the water pump is connected to one end of the first water pipe, and the other end of the first water pipe is connected to the mixing tank body.

[0010] Furthermore, the water storage mechanism includes several water tanks and one or more second water pipes; the several water tanks are of the same height and are evenly distributed along the circumferential direction of the mixing tank and installed on the outer side wall of the mixing tank, and any two adjacent water tanks are connected together through the second water pipes; the water inlet is located at the upper end of any one of the several water tanks, and the water outlet is located at the lower end of any one of the several water tanks.

[0011] Furthermore, it also includes a moving device, which includes a connecting frame, a drive motor, pulleys, and a guide rail; the connecting frame is provided with a pulley connecting end and a mixing tank connecting end; the drive motor is installed on the pulley connecting end, and the pulley is coaxially installed on the output shaft of the drive motor; the pulley is installed on the guide rail and can reciprocate on the guide rail under the drive of the drive motor; the mixing tank connecting end is installed on the mixing tank body.

[0012] Furthermore, a first circular groove is formed on the upper surface of the mixing tank cover at a position corresponding to the lower end of the mixing tank body. The first circular groove is filled with a first sealing ring. When the mixing tank cover is closed on the opening at the lower end of the mixing tank body, the first sealing ring is in close contact with the lower end of the mixing tank body.

[0013] The present invention has the following advantages:

[0014] 1. In this invention, the mixing and sprinkling devices in existing sea cucumber seedling feeders are integrated into a single design, resulting in an integrated feed mixing and sprinkling device. When the mixing tank cover is closed at the lower opening of the mixing tank body, the impeller inside the mixing tank can mix the material inside. When the mixing tank cover is detached from the lower opening of the mixing tank body by the electric cylinder, the material inside the mixing tank can be sprinkled into the pond or net cage through the gap between the mixing tank body and the mixing tank cover under the action of centrifugal force generated by the rotation of the impeller. Therefore, the integrated feed mixing and sprinkling device in this invention can achieve both mixing and sprinkling of the material. At the same time, the integrated feed mixing and sprinkling device in this invention has a similar volume to the mixing device in existing sea cucumber seedling feeders. Therefore, compared with existing sea cucumber seedling feeders, this invention reduces the volume of the sprinkling device, making the automatic sea cucumber seedling feeder provided by this invention more portable and flexible.

[0015] 2. In this invention, a quantitative feeding device is also designed. In use, a certain amount of bait needs to be fed into the feed box through the feed box inlet. Under the action of gravity, the bait in the feed box will be fed into the feeding sleeve through the feed box outlet and the sleeve inlet in sequence. The spiral blades in the feeding sleeve rotate around their axis under the drive of the auger motor, thereby pushing the bait in the feeding sleeve to the sleeve outlet. The bait at the sleeve outlet is fed into the mixing tank through the mixing tank inlet. This invention can quantitatively feed the bait into the mixing tank by controlling the start and stop of the auger motor.

[0016] 3. In this invention, a water conveying device is also designed. When in use, water needs to be input into the water storage mechanism through the water inlet. When water needs to be input into the mixing tank, the water pump is controlled to enter the working state. The water in the water storage mechanism will be input into the mixing tank through the first water pipe under the action of the water pump.

[0017] 4. In this invention, a mobile device is also designed. By controlling the drive motor to enter the working state, the pulley can be driven to reciprocate on the guide rail. Since the mixing tank is installed on the pulley through the connecting frame, when the pulley reciprocates on the guide rail, the integrated bait mixing and throwing device will also reciprocate along the guide rail, thereby evenly throwing the material in the mixing tank into the pond or net cage.

[0018] Based on the above reasons, this invention can be widely promoted in fields such as aquaculture. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] An automatic feeder for sea cucumber seedlings, such as Figure 1 and Figure 3 As shown, the device includes an integrated bait mixing and distributing device 4, which comprises a mixing tank 402, a mixing tank cover 403, an electric cylinder 401, and a bait mixing and distributing mechanism 404. The mixing tank 402 is a cylindrical structure with its axis perpendicular to the horizontal plane and its upper end closed while its lower end is open. A mixing tank inlet is located at the upper end of the mixing tank 402. The mixing tank cover 403 is located directly below the mixing tank 402 and is detachably fitted onto the lower opening of the mixing tank 402. The extension and retraction direction of the electric cylinder 401 is consistent with the axial direction of the mixing tank 402. One end of the cylinder 401 is mounted on the mixing tank body 402, and the other end of the electric cylinder 401 is mounted on the mixing tank cover 403. The bait mixing and throwing mechanism 404 includes a pulsator motor 4043 and a pulsator. The pulsator motor 4043 is mounted on the mixing tank cover 403. The output shaft of the pulsator motor 4043 extends upward along the axis of the mixing tank body 402. The pulsator is coaxially mounted on the output shaft of the pulsator motor 4043 and is located directly above the mixing tank cover 403. When the mixing tank cover 403 is closed at the opening at the lower end of the mixing tank body 402, the pulsator is located inside the mixing tank body 402.

[0026] Specifically, a first rotating shaft is coaxially mounted on the output shaft of the impeller motor 4043 via a first coupling, and the impeller is coaxially mounted on the first rotating shaft.

[0027] Specifically, it also includes a protective housing for the impeller motor. The protective housing for the impeller motor is a cylindrical structure with its axis perpendicular to the horizontal plane and an open top and a closed bottom. The upper end of the protective housing for the impeller motor is detachably mounted on the lower surface of the mixing tank cover 403. The first coupling and the housing of the impeller motor 4043 are both located inside the protective housing for the impeller motor.

[0028] Specifically, a second circular groove is formed on the upper surface of the protective shell of the impeller motor, and a second sealing ring is filled in the second circular groove. The second sealing ring is attached to the lower surface of the mixing tank cover 403.

[0029] The protective housing of the impeller motor is fitted over the housing of the first coupling and the impeller motor 4043, which can protect the first coupling and the impeller motor 4043. At the same time, a second sealing ring is provided between the protective housing of the impeller motor and the mixing tank cover 403 to prevent external liquid from entering the protective housing of the impeller motor through the gap between the protective housing of the impeller motor and the mixing tank cover 403, thereby preventing damage to the impeller motor 4043 and the first coupling.

[0030] In this embodiment, as Figure 3 As shown, the impeller includes a rotating disk 4042 and a plurality of stirring and spraying ribs 4041; the rotating disk 4042 is coaxially mounted on the output shaft of the impeller motor 4043 and is located directly above the mixing tank cover 403; the stirring and spraying ribs 4041 are mounted on the upper surface of the rotating disk 4042 and extend radially from the axis of the rotating disk 4042 to the edge of the rotating disk 4042.

[0031] Specifically, four stirring and spraying ribs 4041 are installed on the upper surface of the rotating disk 4042, and the included angle between any two adjacent stirring and spraying ribs 4041 is 90°.

[0032] When the mixing tank cover 403 is closed on the opening at the lower end of the mixing tank body 402, the impeller inside the mixing tank body 402 can stir the material inside the mixing tank body 402. When the mixing tank cover 403 is disengaged from the opening at the lower end of the mixing tank body 402 by the electric cylinder 401, the material inside the mixing tank body 402 can be thrown into the pond or net cage through the gap between the mixing tank body 402 and the mixing tank cover 403 under the action of centrifugal force generated by the rotation of the impeller. Therefore, the integrated feed mixing and throwing device 4 in this embodiment can realize both the mixing and throwing of materials. At the same time, the integrated feed mixing and throwing device 4 in this embodiment is similar in size to the mixing device in the existing sea cucumber seedling feeding machine. Therefore, this embodiment reduces the size of the throwing device compared with the existing sea cucumber seedling feeding machine, making the automatic sea cucumber seedling feed feeding machine provided in this embodiment more convenient and flexible.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, it also includes a quantitative feeding device 2, which includes a material box 201 and a screw feeding mechanism 202; the upper end of the material box 201 has a material box inlet, and the lower end of the material box 201 has a material box outlet; the screw feeding mechanism 202 includes a feeding sleeve 2022, a auger motor 2023, and a screw blade 2021; the feeding sleeve 2022 is a cylindrical structure with its axis parallel to the horizontal plane and both ends closed, and a sleeve is formed on the side wall of the upper end of the feeding sleeve 2022. The feeding inlet and the feeding sleeve 2022 have a sleeve outlet on the lower side wall. The sleeve inlet is connected to the material box outlet and the sleeve outlet is connected to the mixing tank inlet. The auger motor 2023 is installed on one end of the feeding sleeve 2022, and the output shaft of the auger motor 2023 extends along the axis of the feeding sleeve 2022 to the other end of the feeding sleeve 2022. The spiral blade 2021 is coaxially installed on the output shaft of the auger motor 2023 and located inside the feeding sleeve 2022.

[0034] Specifically, a second rotating shaft is coaxially mounted on the output shaft of the auger motor 2023 via a second coupling, and the spiral blade 2021 is coaxially mounted on the second rotating shaft.

[0035] Specifically, the feeding sleeve 2022 includes a front cover, a rear cover, and a sleeve sidewall. The front cover is detachably fitted onto one end of the sleeve sidewall, and the rear cover is detachably fitted onto the other end of the sleeve sidewall. A third sealing ring is provided between the front cover and the sleeve sidewall, and between the rear cover and the sleeve sidewall. A U-shaped motor base is installed on the front cover. The open end of the motor base is detachably installed on the front cover. The auger motor 2023 is installed on the closed end of the motor base, and the second coupling is located inside the motor base.

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

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the material box 201 has a trumpet-shaped structure with the larger opening facing upwards and the smaller opening facing downwards; the larger opening of the material box 201 is the material inlet of the material box 201, and the smaller 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 needs to be fed into the feed box 201 through the feed box inlet. Under the action of gravity, the bait in the feed box 201 will be fed into the feeding sleeve 2022 through the feed box outlet and the sleeve inlet along the side wall of the feed box 201. The spiral blade 2021 in the feeding sleeve 2022 rotates around its axis under the drive of the auger motor 2023, thereby pushing the bait in the feeding sleeve 2022 to the sleeve outlet. The bait at the sleeve outlet is fed into the mixing tank 402 through the mixing tank inlet. In this embodiment, the bait can be quantitatively fed into the mixing tank 402 by controlling the opening and closing of the auger motor 2023.

[0039] In this embodiment, as Figure 1 As shown, it also includes a water conveying device 3, which includes a water storage mechanism, a water pump 304, and a first water pipe 303. The water storage mechanism is installed on the mixing tank 402, with an inlet at the upper end and an outlet at the lower end. The input end of the water pump 304 is connected to the outlet of the water storage mechanism, and the output end of the water pump 304 is connected to one end of the first water pipe 303. The other end of the first water pipe 303 is connected to the mixing tank 402.

[0040] In this embodiment, as Figure 1 As shown, the water storage mechanism includes several water tanks 301 and one or more second water pipes 302; the several water tanks 301 are of the same height and are evenly distributed along the circumferential direction of the mixing tank body 402 and installed on the outer side wall of the mixing tank body 402, and any two adjacent water tanks 301 are connected together through the second water pipes 302; the water inlet is opened at the upper end of any one of the several water tanks 301, and the water outlet is opened at the lower end of any one of the several water tanks 301.

[0041] When using the water supply device 3, water must first be introduced into the water storage mechanism through the water inlet. When water needs to be introduced into the mixing tank 402, the water pump 304 is controlled to enter the working state. The water in the water storage mechanism will be introduced into the mixing tank 402 through the first water pipe 303 under the action of the water pump 304. After a certain amount of water is introduced into the mixing tank 402, the impeller motor 4043 is controlled to enter the working state. The impeller can then stir the mixture of bait and water in the mixing tank 402 under the drive of the impeller motor 4043, thereby diluting the bait in the mixing tank 402.

[0042] In this embodiment, as Figure 1As shown, it also includes a moving device 1, which includes a connecting frame 104, a drive motor 101, a pulley 103, and a guide rail 102; the connecting frame 104 is provided with a pulley 103 connecting end and a mixing tank connecting end; the drive motor 101 is installed on the pulley 103 connecting end, and the pulley 103 is coaxially installed on the output shaft of the drive motor 101; the pulley 103 is installed on the guide rail 102 and can reciprocate on the guide rail 102 under the drive of the drive motor 101; the mixing tank connecting end is installed on the mixing tank body 402.

[0043] By controlling the drive motor 101 to enter the working state, the pulley 103 can be driven to reciprocate on the guide rail 102. Since the mixing tank 402 is installed on the pulley 103 through the connecting frame 104, when the pulley 103 reciprocates on the guide rail 102, the integrated feed mixing and spreading device 4 will also reciprocate along the guide rail 102, thereby evenly spreading the diluted feed in the mixing tank 402 into the pond or net cage.

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

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

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
