[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please see Figures 1-10 In this embodiment of the invention, a fish farming feed mixing device for offshore aquaculture includes a protective box 1, multiple storage boxes 19 disposed above the protective box 1, and a mixing tank 6 disposed inside the protective box 1. The protective box 1 has an installation cavity 101 inside, and a sliding block 2 is disposed within the installation cavity 101. The mixing tank 6 is fixedly mounted on the sliding block 2. The protective box 1 is equipped with a driving mechanism for driving the sliding block 2 to move horizontally within the installation cavity 101. A discharge assembly is disposed at the bottom of each storage box 19, with its bottom extending into the mixing cavity. A stirring mechanism is disposed inside each storage box 19. The mixing tank 6 has a lid 7 at the top, with a feed inlet 701 on the lid 7 and a sealing opening above the feed inlet 701. Component 1: When the feed inlet 701 of the mixing tank 6 moves below the discharge component, the sealing component 1 opens, allowing the feed in the storage tank 19 to enter the mixing tank 6 through the discharge component and the feed inlet 701. During operation, the mixing tank 6 moves horizontally within the mixing chamber under the drive of the drive mechanism, thus moving below each storage tank 19 for feeding. After feeding, the feed in the mixing tank 6 is stirred by the stirring mechanism to complete the mixing process. The entire feeding process takes place inside the protective box 1, and the sealing component 1 is only opened during feeding, effectively preventing external gas from entering the mixing tank 6, thus improving the service life of the device. Furthermore, it enables automatic feeding, reducing labor costs and improving batching efficiency and accuracy.

[0022] In this embodiment, preferably, the driving mechanism includes a first motor 5, a driving screw 3, and a guide post 4. The driving screw 3 is rotatably installed inside the mounting cavity 101, and the guide post 4 is fixedly installed inside the mounting cavity 101. Both the driving screw 3 and the guide post 4 penetrate the slide block 2. The driving screw 3 is threadedly connected to the slide block 2, and the guide post 4 is slidably connected to the slide block 2. The first motor 5 is fixedly installed on the side wall of the protective box 1, and the output end of the first motor 5 is fixedly connected to the end of the driving screw 3. A protective structure is provided on the first motor 5 to prevent seawater from entering the interior of the first motor 5. The specific protection method is existing technology and will not be described in detail here. The first motor 5 can drive the driving screw 3 to rotate. When the driving screw 3 rotates, it drives the slide block 2 to move horizontally, thereby driving the mixing tank 6 to move horizontally, so that the mixing tank 6 can move to the bottom of each storage box 19 to collect the feed discharged from each storage box 19. The guide post 4 can guide the slide block 2 to improve the stability of the movement of the slide block 2.

[0023] In this embodiment, preferably, the sealing assembly includes a sealing plate 12, a connecting seat 13, a connecting shaft 14, and a reset assembly. The sealing plate 12 is disposed on the can lid 7 to seal the feed hole 701. The sealing plate 12 is fixedly connected to the connecting seat 13, and the connecting shaft 14 is fixedly connected to the connecting seat 13. The connecting shaft 14 is mounted on the reset assembly. The reset assembly includes a mounting base 15, a reset plate 16, a mounting plate 17, and two arc-shaped springs 18. The mounting base 15 is embedded in the interior of the can lid 7 and is hollow. The connecting shaft 14... The bottom end of the plate extends into the interior of the mounting base 15, and the connecting shaft 14 is rotatably connected to the mounting base 15. The reset plate 16 is fixedly installed on one side of the bottom of the connecting shaft 14, and the mounting plate 17 is fixedly installed inside the mounting base 15. Two arc-shaped springs 18 are symmetrically arranged inside the mounting base 15. One end of the arc-shaped spring 18 is fixedly connected to the reset plate 16, and the other end of the arc-shaped spring 18 is fixedly connected to the mounting plate 17. When the two arc-shaped springs 18 are in their natural state, the reset plate 16 and the mounting plate 17 are on the same straight line, and at this time, the sealing plate 12 closes the feed hole 701.

[0024] In this embodiment, preferably, the discharge assembly includes a discharge cylinder 22 and a solenoid valve 23. The discharge cylinder 22 is fixedly installed at the bottom of the storage tank 19, and the discharge cylinder 22 penetrates the top wall of the protective box 1. The discharge cylinder 22 does not contact the protective box 1, and the discharge cylinder 22 is connected to the storage tank 19. The solenoid valve 23 is provided on the discharge cylinder 22. A push ring 24 is sleeved on the bottom of the discharge cylinder 22. The push ring 24 does not contact the discharge cylinder 22. Multiple balls 25 are embedded in the outer peripheral wall of the push ring 24. A connecting rod 26 is fixedly connected to the push ring 24, and the top end of the connecting rod 26 is fixedly connected to the top inner wall of the protective box 1. When the slide 2 drives the mixing tank 6 to move horizontally, as the balls 25 on the push ring 24 contact the sealing plate 12, the push ring 24 pushes the sealing plate 12. Rotating around the connecting shaft 14 as the rotation center, the feed inlet 701 on the top of the tank cover 7 opens. When the mixing tank 6 moves to the point where the discharge cylinder 22 is coaxial with the feed inlet 701, the solenoid valve 23 opens, allowing the feed in the storage tank 19 to be fed into the mixing tank 6 through the discharge cylinder 22. After feeding is completed, as the push ring 24 separates from the sealing plate 12, under the elastic action of the two arc springs 18, the sealing plate 12 is driven to rotate through the reset plate 16 and the connecting shaft 14, so that the sealing plate 12 is reset. The setting of the ball bearing 25 can reduce the friction when the push ring 24 pushes the sealing plate 12 open, and the push ring 24 does not contact the discharge cylinder 22, so that the reaction force when the sealing plate 12 moves will not act on the discharge cylinder 22, thus preventing the sealing plate 12 from affecting the weighing accuracy of the weighing platform 20.

[0025] In this embodiment, preferably, the upper surface of the protective box 1 is equipped with multiple weighing platforms 20, and the storage box 19 is installed on the weighing platform 20. The weighing platform 20 is used to weigh the storage box 19. The weighing platform 20 is equipped with a display panel 21, which can display the weight of the storage box 19 and the feed inside, so as to replenish the feed in time. In addition, the device is equipped with a control module, which is connected to the first motor 5, the second motor 8, the weighing platform 20 and the solenoid valve 23. The control module can control the first motor 5, the second motor 8 and the solenoid valve 23 to work, so as to control the mixing tank 6 to move to the bottom of each storage box 19 to put the feed in, and control the weight of the feed put in by weighing the weighing platform 20. Different feeds are placed in each storage box 19 for automatic feeding.

[0026] In this embodiment, preferably, gas storage tanks 30 are fixedly installed on both sides of the top of the protective box 1, and two air outlets 31 are fixedly installed on the top of the inner cavity of the mounting cavity 101. The output end of the gas storage tank 30 is connected to the air outlets 31 through a valve. The gas storage tank 30 stores inert gas, such as nitrogen. When the mixing tank 6 is mixing and discharging, the gas storage tank 30 discharges inert gas through the air outlets 31. The inert gas enters the mounting cavity 101. When the sealing plate 27 is opened, the inert gas is discharged through the discharge channel 103. The overflowing airflow can effectively prevent outside air from entering the mounting cavity 101, thereby avoiding corrosion of the internal environment of the protective box 1. Even if there is a problem with the sealing of the protective box 1, outside air can be prevented from entering the mounting cavity 101 by discharging inert gas during the blanking process, which effectively improves the service life of the device.

[0027] In this embodiment, preferably, there are two feed holes 701 and two sealing components, and two rows of storage tanks 19 are provided, so that the two storage tanks 19 can be controlled to feed materials into the mixing tank at the same time during the batching process, thereby improving the batching efficiency.

[0028] In this embodiment, preferably, the bottom wall of the protective box 1 is fixedly provided with a plurality of support plates 102, which support the protective box 1 to a certain height, so that the receiving device or feeding device can move to the bottom of the discharge channel 103.

[0029] Please see Figures 5-11 In this embodiment of the invention, the bottom of the mixing tank 6 is provided with a conical part 601, and the bottom of the conical part 601 is provided with a discharge port 602. When the bottom wall of the conical part 601 is in contact with the bottom inner wall of the protective box 1, the discharge port 602 is sealed. When the mixing tank 6 moves to the point where the discharge port 602 is connected to the discharge channel 103, it automatically discharges material without the need for a separate valve structure to block the discharge port 602, thus reducing the production cost of the equipment.

[0030] In this embodiment, preferably, the stirring mechanism includes a second motor 8, a stirring shaft 9, a first stirrer 10, and a second stirrer 11. The second motor 8 is fixedly installed on the upper surface of the tank cover 7. The top end of the stirring shaft 9 is fixedly connected to the output end of the second motor 8. Both the first stirrer 10 and the second stirrer 11 are fixedly connected to the stirring shaft 9. The first stirrer 10 is disposed inside the mixing tank 6, and the second stirrer 11 is disposed inside the conical part 601. The second motor 8 can drive the stirring shaft 9 to rotate. When the stirring shaft 9 rotates, it drives the first stirrer 10 and the second stirrer 11 to rotate, thereby mixing the feed in the mixing tank 6. The second stirrer 11 can be used to specifically mix the feed inside the conical part 601 to improve the mixing efficiency.

[0031] In this embodiment, preferably, discharge channels 103 are provided on both sides of the bottom wall of the protective box 1. A sealing assembly 2 is provided above the discharge channel 103. The sealing assembly 2 includes a sealing plate 27, a connecting cylinder 28, and a connecting post 29. The sealing plate 27 is disposed on the discharge channel 103. The connecting cylinder 28 is fixedly connected to the inner wall of the mounting cavity 101. One end of the connecting post 29 is fixedly connected to the sealing plate 27, and the other end of the connecting post 29 extends into the connecting cylinder 28, and the connecting post 29 and the connecting cylinder 28 are slidably engaged. A spring (not shown in the figure) is provided inside the connecting cylinder 28. One end of the spring is fixedly connected to the inner wall of the connecting cylinder 28, and the other end of the spring is fixedly connected to the end of the connecting post 29. When the mixing tank 6 moves to the safe position... When the feed is loaded onto both sides of the inner cavity of the cavity 101, the conical part 601 pushes open the sealing plate 27, so that the discharge port 602 is connected to the discharge channel 103. When the sealing plate 27 is not under force, the sealing plate 27 closes the top opening of the discharge channel 103. After the feed inside the mixing tank 6 is mixed, the mixing tank 6 moves to both sides of the inner cavity of the cavity 101, so that the conical part 601 at the bottom of the mixing tank 6 pushes open the sealing plate 27, so that the connecting column 29 retracts into the connecting cylinder 28, thereby connecting the discharge channel 103 with the discharge port 602, so that the feed mixed in the mixing tank 6 can be discharged through the discharge channel 103. A receiving device can be set below the discharge channel 103 for receiving or a feeding device can be set for direct feeding.

[0032] Working principle: After the device is started, the control module first links the weighing platform 20 to weigh each storage bin 19, and the display panel 21 provides feedback on the material quantity to ensure sufficient raw materials. At the same time, the gas storage tank 30 delivers inert gas to the gas outlet 31 at the top of the installation cavity 101 through the valve to form an overflow airflow, creating a closed environment to prevent the intrusion of external media. Then, the control module drives the first motor 5 to rotate, which drives the drive screw 3 to rotate, so that the slide 2 moves stably in the horizontal direction, thereby moving the mixing tank 6 on the slide 2 to below the target storage bin 19; during the movement, the ball bearings 2 of the push ring 24 at the bottom of the discharge cylinder 22... 5 contacts the sealing plate 12 of the can lid 7 and pushes it to rotate around the connecting shaft 14, so that the feed hole 701 opens. When the feed hole 701 is coaxial with the discharge cylinder 22, the control module controls the solenoid valve 23 to open. The feed in the storage box 19 is put into the mixing tank 6 through the discharge cylinder 22 and the feed hole 701. The weighing platform 20 monitors the weight change of the storage box 19 in real time to control the feeding amount. After the feeding is completed, the mixing tank 6 continues to move. The sealing plate 12 closes the feed hole 701 under the reset action of the arc spring 18. This process can be carried out by simultaneously connecting two rows of storage boxes 19 through the double feed hole 701 structure, which improves efficiency. After all raw materials are fed, the control module starts the second motor 8 to drive the stirring shaft 9 to rotate, which drives the agitator 10 and agitator 21 to fully mix the feed in the main body of the mixing tank 6 and the bottom conical part 601. After the mixing is completed, the control module controls the drive mechanism again to move the mixing tank 6 to the discharge channel 103 above the bottom wall of the protective box 1. During the movement, the conical part 601 at the bottom of the mixing tank 6 pushes open the sealing plate 27 on the discharge channel 103, causing the connecting column 29 to retract into the connecting cylinder 28 and compress the spring. At this time, the discharge port 602 of the mixing tank 6 is connected to the discharge channel 103, and the mixed feed is discharged through the discharge channel 103 to the receiving or feeding device below. After the discharge is completed, the mixing tank 6 leaves the area of ​​the discharge channel 103, and the sealing plate 27 closes the discharge channel 103 under the action of the spring reset. At the same time, the gas storage tank 30 stops supplying gas. The device completes a single mixing process and can repeat the above steps to make the mixing tank 6 move back and forth left and right for continuous operation.

[0033] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
