Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to an aquaculture feeding device and system. Background Art

[0002] In the field of aquaculture, especially in small-scale shrimp farming, feeding is a key factor affecting aquaculture yield and profitability. Existing small-scale shrimp farming is usually 20-40 meters long and about 10 meters wide. Its special spatial structure places high demands on the performance of feeding equipment.

[0003] The feeding methods of the prior art mainly include the following: 1. Artificial feeding: Common in small-scale shrimp farming. Farmers manually throw feed into the water.

[0004] 2. Fixed-point feeding: widely used in factory farming. Feed is delivered through a feeding machine fixed at a certain location.

[0005] 3. Air-blowing feeding: The feeding machines used by a small number of individual households adopt the air-blowing feeding method, using gas pipes to blow the feed into the water.

[0006] The applicant has discovered that the prior art has at least the following technical problems: For the small-shed shrimp farming model, fixed-point feeding cannot evenly distribute the feed into the water body, which will lead to regional imbalances in shrimp density during the farming process. That is, high-density areas compete for feed resources, while low-density areas waste feed, which in turn affects shrimp production and feed utilization. Due to the high humidity and fluctuating temperatures in the farming environment, air-blown feeding easily produces condensation on the inner wall of the pipe, causing the feed to become damp and sticky, clogging the pipe, thereby affecting the feeding effect. In addition, the air pressure and airflow in the pipe are not stable, which will also have an adverse effect on the uniformity of feed delivery and poor long-term operational reliability. Manual feeding has the problems of high labor intensity, low efficiency, reliance on personal experience for feeding uniformity, and uncontrollable feed coverage.

[0007] Therefore, there is an urgent need for an aquaculture feeding device and system to solve the above problems. Summary of the Invention

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0026] Example 1 Figure 1 Schematic diagram of the structure of this embodiment, Figure 2 yes Figure 1 Internal structural diagram, such as Figure 1 and Figure 2 As shown, the aquaculture feeding device includes a storage component 1, a metering component 2, a spreading component 3, a frame 4, and a moving component 5. The storage component 1, metering component 2, and spreading component 3 are sequentially arranged on the bearing surface of the frame 4 from top to bottom, and the moving component 5 is arranged at the bottom of the frame 4.

[0027] The aquaculture feeding device in this embodiment is about 78 cm high, 45 cm wide and 54 cm long. The overall structure is adapted to the size of the aisle in the middle of the small shed, and a safe distance is reserved on both sides to avoid collision with facilities in the shed and ensure smooth feeding.

[0028] Figure 3 This is a schematic diagram of the structure of the connection between the storage assembly and the frame in this embodiment. Figure 4 It is a structural diagram of the barrel, such as Figure 3 and Figure 4 As shown, the storage assembly 1 is used to accommodate feed to be fed, and includes a barrel 11 and a cover 12. A discharge port 110 is provided at the bottom of the barrel 11; the cover 12 is provided at the top of the barrel 11; and a detection element 13 is provided on the side wall of the barrel 11 for detecting the amount of feed inside the barrel 11.

[0029] The barrel body 11 in this embodiment adopts a square structure, and a conical discharge port 110 is provided at the bottom. The cover plate 12 is hinged to the top of the barrel body 11 and is used for flipping the cover to add materials. Specifically, in this embodiment, the total storage volume of the barrel body 11 is 37.23 dm³. According to the effective volume of 90% and the feed density of 0.6 kg / dm³, 20.10 kg of material can be stored. A detection element 13 is provided on the side wall of the barrel body 11. The detection element 13 can use a laser ranging sensor to measure the amount of material in the barrel body 11 by measuring the distance from the surface of the feed to the sensor in real time. When the remaining amount of material is less than a preset value, such as 2 kg, the sensor can trigger the control system 30 to alert the breeder to add material through sound and light alarms.

[0030] Figure 5is a schematic diagram of the structure of the metering component in this embodiment, such as Figure 5 As shown, the metering component 2 includes a metering body 21 and a metering drive device 22 for driving the metering body 21. The metering drive device 22 in this embodiment adopts a motor. The metering component 2 is used to control the feeding amount of feed.

[0031] Figure 6 Schematic diagram of the structure of the material spreading component in this embodiment. Figure 6 As shown, the material spreading assembly 3 includes a material distribution chute 31 , a material throwing bin 32 located at the bottom of the material distribution chute 31 , and a curved fan blade 33 arranged in the material throwing bin 32 .

[0032] Specifically, the metering body 21 in this embodiment includes a metering chamber 210 and a plurality of spoon-shaped metering members 211. Figure 7 It is a structural diagram of the metering bin in this embodiment. Figure 8 Schematic diagram of the structure of the spoon-shaped measuring member in this embodiment. Figure 7 and Figure 8 As shown, the top of the metering bin 210 is connected to the material storage assembly 1, and the bottom of the metering bin 210 is provided with a discharge port connected to the material distribution chute 31; the spoon-shaped metering piece 211 is arranged in the metering bin 210 and is distributed in a circular array, and the metering drive device 22 can drive the spoon-shaped metering piece 211 to rotate through the transmission mechanism 23, and the rotation direction of the spoon-shaped metering piece 211 is perpendicular to the discharge direction.

[0033] In this embodiment, four groups of spoon-shaped measuring members 211 are provided. The rotation speed of the spoon-shaped measuring members 211 is controlled by a motor to control the weight of the feed. The volume of each spoon is designed to be 11.74 cm³, and the weight of the spoon after one rotation is about 28.18 g. When working, the rotation speed can be designed to be 14-45 r / min. At the maximum rotation speed of 45 r / min, 9 kg of bait can be fed in three round trips.

[0034] Figure 9 This is a schematic diagram of the structure inside the throwing bin in this embodiment. Figure 2 、 Figure 6 and Figure 9 As shown, the distribution chute 31 is used to receive the feed dumped by the metering body 21 and guide it into the throwing bin 32. The arc fan blade 33 is connected to the throwing drive device 35 through the rotating shaft 34. The throwing drive device 35 in this embodiment adopts a motor.

[0035] Figure 10 Schematic diagram of the structure of the radian blade in this embodiment. Figure 10 As shown, a plurality of collision zones with different normal angles are provided on the surface of the curved blade 33 so as to cause the feed to be projected radially in all directions after contacting the curved blade.

[0036] By setting up multiple collision zones with different normal angles on the surface of the curved blades 33, such as points A, B, and C, with the normal angles at points A, B, and C varying in gradients, such as 30°, 45°, and 60°, when feed particles strike different points, they acquire different initial velocities in direction and magnitude according to the law of conservation of momentum, causing the feed to be projected radially in multiple trajectories. This solves the problems of limited coverage and poor uniformity of traditional bait throwers.

[0037] As an optional implementation, the distribution chute 31 in this embodiment is directly opposite to the bottom of the metering bin 210, and the top width of the distribution chute 31 is larger than the rotation track diameter of the spoon-shaped metering piece 211, ensuring that when the spoon-shaped metering piece 211 rotates to discharge the feed, the feed particles can fall into the distribution chute 31 regardless of the angle from which the spoon-shaped metering piece 211 is thrown out, so that the feed is received without omission.

[0038] The depth direction of the distribution chute 31 is perpendicular to the rotation axis of the spoon-shaped metering piece 211, and the central axis of the distribution chute 31 is collinear with the central axis of the throwing bin 32 in the vertical direction, so that the feed is accelerated to fall under the action of gravity, thereby increasing the feeding rate and effectively avoiding the problem of feed accumulation caused by the bending path.

[0039] Moreover, since the central axis of the distribution chute 31 and the central axis of the throwing bin 32 are arranged collinearly in the vertical direction, the initial position of the feed entering the throwing bin 32 is always located in the central area of ​​the curved fan blade 33, ensuring that the position where the feed hits the fan blade is fixed. Combined with the differentiated normal angles on the surface of the curved fan blade 33, the feed can be evenly radiated and thrown in all directions, thereby forming a stable throwing trajectory.

[0040] As an optional implementation, Figure 6 As shown, the feed distribution chute 31 in this embodiment includes a slot 311 and a diversion structure 312. The slot 311 is used to receive the feed discharged from the metering body 21; the diversion structure 312 is arranged obliquely at the bottom of the slot 311, with the end extending into the inside of the throwing bin 32 and located above the curved blade 33, and is used to evenly guide the feed in the slot 311 into the throwing bin 32.

[0041] As an optional implementation, Figure 9 As shown, the diversion structure 312 in this embodiment includes a first diversion structure 3121 and a second diversion structure 3122 arranged in an inverted "V" shape. The first diversion structure 3121 and the second diversion structure 3122 are used to evenly guide the feed in the slot 311 to the two side areas of the curved fan blades 33 in the throwing bin 32.

[0042] By setting the diversion structure 312 in an inverted "V" shape, the feed dropped from the metering component 2 can be evenly divided according to geometric symmetry, avoiding the accumulation of feed at the diversion point. When the feed falls into the slot 311 at the top of the distribution chute 31, it will be guided to both sides by the two inclined surfaces of the inverted "V", ensuring that the deviation of the feed amount on the left and right sides is small when entering the throwing bin 32. The mechanical diversion method does not rely on electricity or air pressure, and is more reliable, especially suitable for the humid environment of aquaculture.

[0043] At the same time, since the curved fan blade 33 is a bilaterally symmetrical structure, the use of an inverted "V" structure for diversion can make the feed fall evenly on both sides of the curved fan blade 33, avoiding the problem of feed being concentrated on one side, resulting in uneven force on the fan blade and increased motor load. Uniform diversion can make the motor run more smoothly, reduce energy consumption, and increase the service life of the motor.

[0044] As an optional embodiment, the ejection bin 32 in this embodiment includes a cavity structure with a closed bottom, and a discharge window 321 connected to the outside is opened on the side wall of the cavity structure. The direction of the discharge window 321 should be consistent with the tangent direction of the rotation plane of the arc fan blade 33.

[0045] When the curved blade 33 rotates, the linear velocity direction of any point on its edge is the tangent direction of that point. By providing a discharge window 321 connected to the outside in the side wall of the ejection bin 32, and aligning the orientation of the discharge window 321 with the tangent direction of the rotation plane of the curved blade 33, the feed pellets are not blocked by the walls of the ejection bin 32 when the curved blade 33 is rotated, and are ejected directly along the inertial trajectory, avoiding velocity attenuation and trajectory deviation caused by collisions with the bin wall. This allows the feed pellets to be radially ejected in all directions, forming a maximum coverage radius for the ejection, effectively solving the problems of uneven throwing and insufficient coverage of conventional baitcasters. In this embodiment, the curved blade 33 is set to rotate at 906 rpm, with a maximum ejection distance of 4.0 m.

[0046] As an optional implementation, Figure 2 As shown, the slot 311 of the material distribution chute 31 is provided with an air inlet 310, and the number of the air inlet 310 is adapted to the diversion structure 312. Each diversion structure 312 corresponds to at least one air inlet 310, and one end of the orifice of the air inlet 310 is connected to the external atmosphere, and the other end points to the feed flow path in the diversion structure 312.

[0047] With this arrangement, when the curved blades 33 rotate at high speed within the feed bin 32, the centrifugal force generated by the curved blades 33 causes the air within the bin 32 to be expelled outward, forming an airflow channel through the air inlet 310 of the slot 311. At this point, the air inlet 310 points toward the feed flow path within the diversion structure 312. The pressure difference between the external atmospheric pressure and the low pressure within the bin creates a stable negative pressure within the feed chute 31. This negative pressure airflow exerts a downward drag on the feed, improving feed discharge efficiency and ensuring continuous and stable feeding.

[0048] Inlet 310 also compensates for diversion. The inverted "V"-shaped diversion structure is affected by feed particle size and humidity, and diversion deviation may occur in extreme conditions. The lateral thrust generated by the airflow from air inlet 310 dynamically adjusts the feed flow direction. For example, if there is excessive diversion on the left side, the airflow from the left air inlet is strengthened, pushing the feed to the right. This achieves adaptive adjustment to improve feed spreading uniformity.

[0049] Furthermore, during the throwing process, some feed that is not completely thrown by the curved blades 33 will be further diffused into the water body under the continuous propulsion of the airflow. Through the dual synergy of mechanical throwing and airflow assistance, the traditional single throwing mode is broken through, and the feed is released from far to near, covering a wider range. This allows for large-scale, multi-directional feeding, effectively meeting the feeding needs of the aquaculture water body and improving feeding efficiency and uniformity.

[0050] Example 2 This embodiment provides an aquaculture feeding system based on the first embodiment. Figure 11 It is a structural diagram of this embodiment, as shown in FIG. Figure 11 As shown, the aquaculture feeding system includes an aquaculture feeding device 10, a track 20 and a control system 30. The track 20 can be installed in the aisle of the breeding shed; the aquaculture feeding device 10 can move on the track 20 through the moving component 5.

[0051] The control system 30 includes a controller 301, which is a PLC. The controller 301 is electrically connected to the material storage component 1, the metering component 2, the material spreading component 3 and the moving component 5.

[0052] Figure 12 It is a working principle diagram of this embodiment, such as Figure 12 As shown, the control system 30 in this embodiment also includes at least a battery module 302, a charging interface 303, a wireless communication module 304, an audible and visual alarm module 305, a touch screen 306 and an emergency stop button 307, and the battery module 302, the charging interface 303, the wireless communication module 304, the audible and visual alarm module 305, the touch screen 306 and the emergency stop button 307 are all electrically connected to the controller 301.

[0053] Battery module 302 utilizes a 12V / 20Ah lithium battery, enabling the device to operate offline for over four hours, meeting the 3-5 daily feeding requirements of small-scale shrimp farming. Compared to traditional plug-in feeders, this eliminates the mobility restrictions caused by dragging cables and meets the electrical safety requirements of humid small-scale environments. Charging port 303 utilizes a waterproof DC outlet, allowing the device to automatically dock and charge via a charging base station.

[0054] Wireless communication module 304 supports WiFi / Bluetooth connectivity, allowing farmers to remotely start and stop the equipment and adjust parameters such as feeding amount and travel speed through a mobile phone app, tablet, or on-site touch screen. Feeding data can also be uploaded to the cloud in real time, supporting historical data query and report generation, providing data support for farming management.

[0055] The sound and light alarm module 305 is used to give voice and / or indicator light flashing alarms when the feed amount is lower than the threshold, the motor is overloaded or the speed is abnormal, or the battery power is lower than the set value. A graded alarm mechanism can be adopted, such as: when the feed amount is lower than the threshold, the red indicator light flashes and the buzzer alarms intermittently; when the motor is overloaded or the speed is abnormal, the yellow indicator light is always on and the buzzer sounds continuously; when the battery power is low, the blue indicator light flashes and a voice prompt "Please charge" is given, so that the breeding personnel can quickly locate the problem.

[0056] The touch screen 306 is used to display data in real time, such as feed quantity, power, travel speed, spreading speed, etc. The touch screen 306 can also display the working status in real time, such as running, paused, and charging; and the touch screen can display fault codes to facilitate quick processing by the farming staff.

[0057] The emergency stop button 307 is used to quickly cut off the power supply after a fault occurs.

[0058] The track 20 in this embodiment is fixed to the middle aisle of the shed using a galvanized square tube. Taking a 30m×10m shed with a feeding amount of 9kg as an example, when working, the moving component 5 is set to move forward at a speed of 12.5m / min, and it takes about 2-3 minutes to travel through one shed, with high feeding uniformity, wide coverage, and high efficiency.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
