Description

Technical Field

[0001] This application relates to the technical field of aquaculture, and in particular to an aquaculture feeding machine. Background Technology

[0002] In modern aquaculture, scientific feeding is a crucial step in ensuring healthy fish growth and improving aquaculture efficiency. However, current feeding operations face significant technical bottlenecks:

[0003] I. Efficiency and quality defects of manual feeding

[0004] In traditional manual feeding, fish farmers must hold containers to hold feed and pour it into the pond. This operation presents two problems: 1. High labor intensity: The repetitive throwing action over a long period of time can easily lead to muscle strain in the arms. According to statistics, the incidence of arm soreness is as high as 85% after two consecutive hours of manual feeding, which seriously affects the continuity of fish farming operations; 2. Poor feeding uniformity: In order to avoid the feed settling in one place, fish farmers need to deliberately scatter the feed, which not only greatly increases the workload (the feeding time per pond is more than 40% longer than that of mechanical feeding), but also makes it difficult to achieve uniform feeding over a large area due to human limitations, resulting in uneven feed distribution and affecting the feeding efficiency of fish.

[0005] II. Limitations of Existing Mechanical Feeding Systems

[0006] Feeding machines have been introduced in some aquaculture scenarios, but existing equipment has core defects: 1. Small feeding coverage: The limited design of the equipment makes the feeding area concentrated, which easily leads to excessive gathering of fish. According to aquaculture observations, the fish density in a small feeding area can reach 3-5 times the normal density; 2. Increased differences in fish growth: When fish are piled up, smaller fish have less opportunity to feed. Due to uneven feeding, the size difference of fish from the same batch can reach 2-3 times that of normal aquaculture, which seriously affects the quality of aquaculture and economic benefits.

[0007] With the development of large-scale and refined aquaculture, traditional feeding methods and existing mechanical feeding equipment can no longer meet the needs of high-efficiency aquaculture. Therefore, developing an aquaculture feeder that balances feeding uniformity and expands the feeding coverage area has become an urgent technical need to solve the pain points of aquaculture feeding and improve aquaculture efficiency. Therefore, to solve the above problems, this application provides an aquaculture feeder. Utility Model Content

[0008] To address the aforementioned problems, this application provides an aquaculture feeding machine.

[0009] This application provides an aquaculture feeding machine, in which a feeding tray is set in the center, and a float is set on the outside to keep the feeding tray floating on the water surface. A feeding bucket is also set above the feeding tray. A protruding section protrudes downward at the center of the bottom of the feeding bucket. A partition plate is welded to the inner wall of the feeding bucket at the top of the protruding section. A set of sluices is opened on the bottom surface of the protruding section and the partition plate respectively. The two sets of sluices are staggered in plan view.

[0010] The tray is electrically driven with a material feeding frame, and a push plate is set between the boss section and the partition. The push plate and the material feeding frame rotate synchronously.

[0011] The staggered troughs set on the boss section and partition make the amount of feed output per batch controllable and facilitate output statistics. The feed rack, together with the feed tray, allows the material to be thrown out, improving the uniformity of feed distribution.

[0012] Preferably, the two sets of drainage grooves on the bottom surface of the boss section and the partition are arranged perpendicularly to each other.

[0013] Preferably, the push plate is fitted with the bottom surface of the partition and the upper end surface of the boss section with clearance, and the side is fitted with the inner wall of the boss section with clearance, and it rotates cyclically inside the boss section.

[0014] Preferably, a motor is installed at the top axis position of the material barrel, and a rotating shaft is installed at the output end of the motor via a coupling. The material feeding frame is installed at the end of the rotating shaft, and the push plate is also installed on the rotating shaft.

[0015] Preferably, the feeding machine is equipped with an energy storage module that supplies power to the motor.

[0016] Preferably, the edge of the material tray is inclined upward, and the bottom of the material feeder and the inner wall of the material tray are fitted with a gap.

[0017] Preferably, a support rod is installed at the bottom of the material tray, and the floats are respectively installed below the end of the support rod.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] By setting a first trough on the boss section and a second trough perpendicular to the first trough on the partition plate, a single quantitative feeding into the boss section can be achieved. In conjunction with the rotation of the push plate inside the boss section, quantitative discharge can be achieved.

[0020] By setting a feeding tray under the feeding hopper to catch any spilled material, and by setting a feeding rack inside the feeding tray, the material is thrown outwards in conjunction with the outer ring of the feeding tray, thereby achieving a larger throwing area and improving the feeding effect.

[0027] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0028] An aquaculture feeding machine, the following is the content of Embodiment 1 of this application, the feed hopper 1 can be set as follows Figure 1 - Figure 4 The shape shown is customized in size according to actual needs. A hollowed-out section is cut into the center of the bottom of the feed hopper 1, and a partition 14 is welded to the hollowed-out section. A raised section 13 is welded to the bottom of the feed hopper 1. The interior of the raised section 13 is hollow, and when combined with the partition 14, it forms a cylindrical space in the middle. A set of troughs is cut into the bottom plates of both the partition 14 and the raised section 13. A second trough 141 is cut into the partition 14, and a first trough 131 is cut into the raised section 13. Both troughs 131 and 241 are fan-shaped structures, each occupying 1 / 6 of their respective plane area. The lines connecting the first and second troughs are perpendicular to each other on the top view. The purpose of this design is that the feed in the feed hopper 1 first falls onto the bottom plate of the raised section 13 through the second trough. If the feed below is not moved, the feed above cannot continue to be output, thus the amount of feed discharged each time is basically fixed. Therefore, this structure allows for a rough estimation of the amount of feed to be fed each time.

[0029] Based on the above structure, a mounting box 7 is welded and fixed at the top of the material barrel 1, and a motor 8 is installed inside the mounting box 7. The motor 8 can be a DC motor 8, model: 80YD-BL013-30-72V DC brushless motor 8. Its output end is connected to a rotating shaft 81 via a coupling. The rotating shaft 81 extends downward through the partition 14 and the boss section 13. A control box 12 is also welded inside the material barrel 1. The control box 12 is mainly used to house the DC battery module 6 and the control module. The battery pack can be either a Chaowei BF7240AT (lithium iron phosphate) lithium battery or a Chaowei 72V32Ah (lead-acid graphene) lead-acid battery. The control module includes a motor 8 controller for controlling the speed and forward / reverse rotation of the motor 8, a logic controller, and also requires protection components (fuse, overvoltage and undervoltage protection modules, leakage protection modules, etc.), signal monitoring and acquisition components (current and voltage sensors to monitor the operating current of the motor 8 and the output voltage of the battery in real time, so as to understand the working status of the motor 8 and the remaining battery power), sensors (such as photoelectric sensors to detect the number of rotations to estimate the amount of feed; infrared sensors to monitor the amount of feed inside the feed hopper 1), power conversion components (power MOSFETs, insulated gate bipolar transistors, etc.: used to control the current of the motor 8 and realize the power conversion of the motor 8 to meet the power requirements under different working conditions), H-bridge circuit (commonly used for driving DC motors 8, which can easily realize the four-quadrant operation of the DC motor 8, such as forward rotation, forward braking, reverse rotation, and reverse braking), and communication components (wireless communication modules: such as Wi-Fi, Bluetooth, 4G / 5G modules, etc., which can realize remote monitoring and control, allowing farmers to remotely view the status of the motor 8, control the operation of the motor 8, and receive equipment fault alarms via mobile phone or computer). Through the cooperation of various components, the rotation of motor 8 drives the rotation of shaft 81, which in turn drives the feed rack 3 and push plate 82 mounted on it to rotate synchronously. The battery ensures a stable power supply and allows the device to be used independently without cables. When the power is out or the feed is insufficient, the device can be towed back to the shore for charging.

[0030] A lid 11 is hinged to the top of the feed hopper 1. The lid 11 is used to cover the top of the feed hopper 1 to prevent water from entering the feed hopper 1, thereby providing good protection for the feed, battery module 6, motor 8, etc. A handle is provided on the lid 11.

[0031] Multiple feed racks 3 are arranged in a circular array, with gaps between them above the feed tray 2, and their shape always corresponds to that of the feed tray 2. Push plate 82, as... Figure 5Two such devices can be configured, arranged symmetrically at the center, with clearance fits between the push plate 82, the boss section 13, and the partition plate 14. During the rotation of the motor 8, the rotating shaft 81 rotates, which in turn drives the feed feeder 3 and the push plate 82 to rotate synchronously. As the push plate 82 rotates, it pushes the feed on the boss section 13 forward. The feed falls downwards into the feed tray 2 when it passes the trough 131. After the push plate 82 pushes away the feed on the boss section 13, the feed in the feed hopper 1 is replenished. The photoelectric sensor in the device counts the number of triggers to determine the number of rotations of the push plate 82. Combined with the amount of feed pushed in one rotation, the total amount of feed dispensed during that operation is calculated. Alternatively, the dispensing amount can be preset via software, and the required number of rotations can be calculated backwards to control the motor 8 to operate at a precise number of rotations.

[0032] The edge of the feed tray 2 is raised upwards to give the thrown feed an initial upward angle, so that the material moves in a parabolic motion, thereby increasing the range of the throw.

[0033] Taking a feed tray 2 with an inner diameter of 80cm, a side skirt width of 15cm, an angle of 30° between the side skirt and the bottom plate, and a feed weight of 2g per pellet leaking from feed hopper 1 as an example, the horizontal extension distance of the side skirt is Δr = 15 * cos30° = 0.1299m. Therefore, the final radius of rotation is r = 0.4 + 0.1299 = 0.5299m. When the feed is thrown out, the vertical component of the centrifugal force needs to overcome gravity, that is: Simplifying, we get the angular velocity formula: Substituting g=9.8m 2 r = 0.5299m; Convert angular velocity to rotational speed. Rotational speed per minute. It can be seen that under this condition, the rotational speed of motor 8 needs to be at least 58 revolutions per minute to throw the material out. Depending on the distance the material needs to be thrown, other rotational speeds of motor 8 can be selected, as long as they are greater than 58 revolutions per minute.

[0034] Two support rods 4 are installed at the bottom of the feed tray 2 via connectors, and floats 5 are installed at the ends of both support rods 4. The floats 5 allow the device to float on the water surface. After the device is filled with feed, it can be sent to a preset position in the water via a bamboo pole or other structure to throw the feed. When the feed is exhausted or the power is cut off, it can be pulled back to the shore by a cable connected to it for recharging and feeding.

[0035] When the total mass of the device, including the internally loaded feed, is 240 kg, the minimum total buoyancy required by the four floats 5 is: F_buoyancy = G = mg = 240 kg * 9.8 N / kg = 2352 N. The buoyancy required by a single float 5 is F_buoyancy = 588 N. Therefore, the minimum volume of float 5 is... That is, at this weight, the volume of float 5 should be greater than 0.06m³. 3 Therefore, if a cube-shaped float 5 is used, its length should be greater than 39cm. The size of the float 5 should be selected according to the mass of the device fully loaded with feed.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
