[0025] In the following, only certain exemplary embodiments are described briefly. As the person skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. The drawings and the description are therefore to be considered as being exemplary in nature and not restrictive.

[0026] As Figure 1 shown, the water culture feeding machine of the application includes a storage bin 1, a feeding bucket 2, a corrugated plate adjusting rod 3, a drive mechanism 4 and a base 5. The following describes each component and its function in detail.

[0027] The storage bin 1 is used to store the feed that needs to be put into the pond during the process of water culture. The storage bin 1 is arranged at the top of the whole feeding machine, and its inside is a hollow structure with a certain volume to accommodate a large amount of feed. In order to ensure that the feed flows out smoothly, a gradually narrowing opening is provided at the bottom thereof to guide the stored feed to the next part. For example, the storage bin 1 can be made of a strong and moisture-proof plastic material, and the inner surface is smooth to reduce residues.

[0028] The feeding bucket 2 is located directly below the storage bin 1, and is mainly used to receive the feed falling from the storage bin 1 and control the specific feeding amount according to the demand. The feeding bucket 2 has an adjustable opening to flexibly adapt to different feeding demands. For example, by operating the corrugated plate adjusting rod 3 connected thereto, the opening size can be dynamically changed to determine the speed and quantity of the feed passing through. This component can also be made of metal or other high-strength corrosion-resistant materials to ensure reliable performance during long-term use.

[0029] The corrugated plate adjustment lever 3 is installed on top of the feeding hopper 2. This device contains multiple levels of scale markings, which can be used by the user to manually and accurately change the position of the adjustment lever, thereby adjusting the size of the opening on the feeding hopper 2, so as to achieve the purpose of accurately controlling the amount of feed each time. The design of the corrugated plate allows for a large adjustment range with small errors. Technically, the corrugated plate adjustment lever 3 and the feeding hopper 2 form a linkage mechanism, in which the adjustment can be maintained at a certain position by a knob, screw or other locking device to ensure stability.

[0030] The drive mechanism 4 is connected to the lower part of the storage bin 1. Its design is mainly to push the feed in the storage bin 1 in a certain direction until it finally enters the feeding hopper 2, avoiding the problem of blockage or uneven material deposition caused by long-term stagnation. This mechanism can be realized by various technical forms, such as screw pushing system, pneumatic conveying, or electric oscillation device. Each specific form will depend on the specific production situation, aiming to efficiently and losslessly complete the auxiliary task of feeding work.

[0031] The base 5 is used to support all other components and constitutes the foundation guarantee of the overall structure. The base 5 is designed with several mounting holes, so it can be easily installed and fixed on the edge of the pond at a suitable place according to the site conditions. These mounting holes can be stably combined through standard screws or other fastening tools, and the material must be strong and tough enough to withstand the weight of the entire mechanical device while resisting the impact of the outdoor environment.

[0032] In order to meet the needs of fish groups at different growth stages, the core solution of an aquaculture feeding machine is to introduce a corrugated plate adjustment lever 3 with multiple scale markings and make it act on the opening size adjustment function of the feeding hopper 2. When the fish group grows or changes its feeding habits during the breeding period, the user only needs to manually adjust the specific parameters of the corrugated plate adjustment lever 3 according to the actual situation, such as moving different preset scale points, to achieve the goal of increasing or decreasing the outlet flow. This fine and simple manual intervention method makes the same device applicable throughout the long-term breeding process, provides appropriate food supply matching the actual breeding state, improves economic efficiency and protects the rational use of resources from being wasted.

[0033] As Figure 2As shown, in one embodiment, the storage bin 1 of the present application is designed with a detachable cover plate 6. The installation position of the cover plate is at the top of the storage bin 1, which is combined with the storage bin 1 through buckling, screwing or other appropriate fastening methods for easy disassembly and maintenance. In order to ensure the cleanliness during the storage of feed, the cover plate is also provided with a filter screen structure inside. The filter screen is made of durable material and is firmly fixed inside the cover plate. By reasonably selecting the pore size of the filter screen, large foreign matter or impurities can be effectively blocked from entering the inside of the storage bin 1.

[0034] Specifically, such a detachable cover plate and its internal filter screen can achieve the technical feature requirements through simple installation steps. For example, in the actual manufacturing process, the filter screen module can be embedded in the cover plate through pre-forming, and the position is fixed by pressing process; then, the whole cover plate is assembled to the upper part of the storage bin 1 through the clamping groove or other standardized interface, so as to ensure the consistency and stability of assembly. Such structure is convenient for subsequent cleaning and replacement of filter components, and improves the convenience of use.

[0035] As shown, Figure 3 In one embodiment, the present application is provided with a funnel-shaped feeding hopper 2, which facilitates the smooth downward flow of feed under the action of gravity and ultimately completes the feeding. In order to achieve more precise control, the bottom of the feeding hopper 2 is provided with an adjusting valve 7, which has an adjustable opening degree and can set the corresponding opening size to adjust the flow of feed according to the needs. The structure of the adjusting valve 7 includes movable parts, which can change the flow area of the valve body by rotating or translating, and its installation position ensures that it can directly act on the flow of feed.

[0036] Specifically, the adjusting valve 7 is firmly combined with the feeding hopper 2 through the connecting piece, which ensures that it will not be dislocated due to external vibration or other factors during use. In manual mode, the user can rotate the angle of the core part in the adjusting valve 7 by operating the handle; while in electric mode, the same function conversion is completed by using motor-driven mode, both of which transmit power to the core control area of the adjusting valve 7 through transmission assembly. For example, in the electric control scheme, the motor output shaft is connected with the linkage rod inside the adjusting valve 7, so as to accurately set the opening angle of the adjusting valve 7.

[0037] As shown, Figure 3As shown, in one embodiment, the corrugated plate adjusting rod 3 of the aquaculture feeding machine of this application achieves a fixed position function by adding a locking mechanism. To ensure the stability of the corrugated plate adjusting rod 3, after the operation of adjusting the size of the feeding hopper 2 opening is completed, it needs to be fixed by a specially designed locking structure to prevent it from shifting due to external vibration or load. In a specific design, a feasible method is to use a screw-on locking nut 8, which is tightened in a designated area of ​​the corrugated plate adjusting rod 3 to complete the limiting function. This structure is simple to install and highly reliable. The locking nut 8 fits tightly with the corrugated plate adjusting rod 3, which can avoid the influence of position changes on the feeding accuracy.

[0038] For example, assembly can be completed as follows: The locking nut 8 is threaded onto the corrugated plate adjusting rod 3 near its outer edge. After adjustment, manually tightening the locking nut 8 will hold the corrugated plate adjusting rod 3 in the target position, while simultaneously ensuring no displacement deviation between the corrugated plate adjusting rod 3 and other components of the feeder. The locking nut 8 is made of a high-strength and corrosion-resistant metal material to ensure compatibility with the overall working environment of the feeder.

[0039] like Figure 2 As shown, in one embodiment, the drive mechanism 4 of the aquaculture feeding machine of this application employs a spiral pushing device 9. This device is located at the bottom of the storage bin 1 and connected to the storage bin 1, used to evenly convey the feed in the storage bin 1 to the feeding hopper 2. Specifically, the spiral pushing device 9 consists of a spiral rod and a matching outer shell. The outer shell is installed at the bottom outlet of the storage bin 1, while the spiral rod passes through the outer shell and can rotate inside. One end of the outer shell is fixedly connected to the bottom of the storage bin 1 via a connector, and the other end is connected to the feeding hopper 2 to ensure that the feed can be smoothly delivered. In addition, the power source of the spiral pushing device 9 is an electric motor, which is connected to the spiral rod through a transmission structure, thereby driving the spiral rod to rotate.

[0040] For example, the motor can be directly connected to the auger via a coupling or pulley. During operation, the rotation of the auger propels the feed in the storage hopper 1 along the outer shell towards the feeding hopper 2. In this process, the design of the outer shell determines the feed flow path, and its tight connection with the storage hopper 1 ensures the stability of the conveying process. This structure can adapt to different feed pellet shapes, and the feed conveying rate can be indirectly adjusted by regulating the motor speed to meet diverse feeding needs.

[0041] like Figure 3 and Figure 4As shown, in one embodiment, the base 5 of the aquatic feeding machine of the present application adopts a special mounting design to adapt to diverse fixing requirements. By providing multiple sets of mounting holes on the base 5, the distance between each set of mounting holes is precisely designed to adapt to different fixing methods. This structure not only enables the feeding machine to be stably installed at the edge of the pond, but also enables reliable fixation in other various scenarios, such as water channels, dikes, or other related locations. The arrangement of multiple sets of mounting holes takes into account the load-bearing capacity and overall balance of the base 5, ensuring that the feeding machine does not deviate or tilt during operation due to external forces.

[0042] These mounting holes on the base 5 can be connected to the fixing elements, such as screws, expansion bolts, etc., according to specific requirements. Different spacing of the mounting holes allows for adjusting the installation method to adapt to different terrain or material conditions, thereby improving the applicability and stability of the equipment. Specifically, the variety of fixing methods can be achieved by changing the connection angle or depth between the base 5 and the fixing point.

[0043] For example, by pre-determining the type of fixing position (such as a wooden frame or a concrete base), the appropriate fastener specifications can be matched by selecting the corresponding spacing of the mounting hole combination. During installation, the fixing elements are sequentially inserted through the selected mounting holes of the base 5 and locked to the fixed surface to achieve stable fixation, while ensuring that the overall structure of the feeding machine is in a horizontal state.

[0044] As shown, Figure 1 In one embodiment, the installation between the storage bin 1 and the feeding hopper 2 of the aquatic feeding machine of the present application has specific spatial requirements, with a distance of 10 to 30 cm. This spacing design is based on the physical properties of the feed and the actual use requirements of the feeding machine, avoiding the phenomenon of limited feed flow due to too small spacing or excessive feed dispersion in the air due to too large spacing. This design aims to ensure smooth transmission of feed from the storage bin 1 to the feeding hopper 2, while preventing feed blockage or other abnormal situations.

[0045] Specifically, in terms of structure, connecting components such as support rings or adjustment frames can be provided at the bottom of the storage bin 1 and above the feeding hopper 2 to fix the distance between the two. The material of the support ring can be made of lightweight and corrosion-resistant metal materials to ensure stability during long-term use. For example, by adjusting the screw rod or locking screw, etc., the gap between the two can be flexibly adjusted within a specified range, and locked when the appropriate distance is reached, to maintain the stability and reliability of the entire feeding machine during operation. This design does not require further changes to the shape and size of the storage bin 1 or the feeding hopper 2 itself, but only needs to optimize the connection method to meet the technical requirements.

[0046] As shown, Figure 3As shown, in one embodiment, the corrugated plate adjusting rod 3 of the present application is provided with multiple scale marks to achieve precise control of the feed dispensing amount. The corrugated plate adjusting rod 3 is installed on the dispensing hopper 2 and forms a close fitting relationship with the dispensing hopper 2. By adjusting the position of the corrugated plate adjusting rod 3, the opening size of the dispensing hopper 2 can be flexibly changed. Each scale mark corresponds to a pre-set opening width, thereby determining the range of feed dispensing amount. The design of the scale mark allows the operator to intuitively select the appropriate feeding amount according to actual needs without the need for complex measurement or calculation process.

[0047] Specifically, the corrugated plate adjusting rod 3 is assembled with the dispensing hopper 2 through threaded connection or sliding groove fixation. When the corrugated plate adjusting rod 3 is rotated or pushed, the structure at one end can directly compress the side wall of the dispensing hopper 2 or pull the movable part of the dispensing hopper 2 through the internal connecting device, thereby changing the geometric shape and opening area of the dispensing hopper 2. For example, if the corrugated plate adjusting rod 3 adopts threaded connection, different length marks can be engraved on its surface. The operator only needs to rotate the adjusting rod to the specified scale position to stably achieve the setting of the predetermined dispensing amount. This structure ensures the consistency and accuracy of the adjustment operation, meeting the actual needs of various aquaculture.

[0048] As shown, Figure 3 In one embodiment, the inner wall of the dispensing hopper 2 of the present application is provided with an anti-slip pattern 10 to enhance the friction between the feed and the inner wall of the dispensing hopper 2 during the dispensing process. The anti-slip pattern 10 can effectively reduce the accumulation of feed particles in a wet and slippery environment. The anti-slip pattern 10 is installed on the inner wall surface of the dispensing hopper 2 through specific design, forming a closely fitted covering layer, and its position and range are optimized according to the actual feed type and dispensing requirements.

[0049] The structure of the anti-slip pattern 10 is usually irregular corrugated or cross grid, with a large roughness coefficient to provide higher friction and prevent feed from sticking to the inside of the dispensing hopper 2 due to moisture or other factors. In addition, to adapt to different feed particle sizes and properties, the depth, width and shape of the anti-slip pattern 10 can be flexibly adjusted according to specific application scenarios.

[0050] For example, the inner wall can be directly processed into a form with anti-slip pattern 10 by mold pressing, or a layer of high wear-resistant material with specific texture characteristics can be coated or bonded to the inner wall of the dispensing hopper 2 to complete the construction of the anti-slip pattern 10. This method ensures the integrity of the component and also facilitates large-scale production.

[0051] As shown, Figure 3As shown, in one embodiment, the wave plate adjusting rod 3 of the present application is provided with an indicator light 11. The indicator light 11 is installed on the side or top end area of the wave plate adjusting rod 3, and maintains a fixed relative position with the wave plate adjusting rod 3. Through this design, when the wave plate adjusting rod 3 is moved, the indicator light 11 can be turned on or change its light state in response to different positions of the wave plate adjusting rod 3, providing instant visual feedback information for the user. The introduction of the indicator light 11 not only enhances the interactivity of the device, but also reduces the risk of misoperation caused by manual judgment, ensuring that the actual feeding amount meets the set value.

[0052] Specifically, the working state of the indicator light 11 can be controlled by the cooperation of circuit elements and sensors. For example, a set of micro switches or contact detection devices are provided at predetermined positions of the wave plate adjusting rod 3. These devices can sense when the adjusting rod moves to a certain interval or trigger point and output an electrical signal, which is then transmitted to the indicator light 11 component via internal circuit to make it energized and lit. In this way, each time the wave plate adjusting rod 3 is adjusted to the right position, the sensing mechanism at the corresponding position will automatically activate the corresponding light signal path, ultimately achieving the function of precise visualization.

[0053] As shown, Figure 2 In one embodiment, the drive mechanism 4 of the present application adopts a speed-regulating motor 12, which is installed at an appropriate position between the storage bin 1 and the base 5, fixed by a bracket and mechanically connected to the bottom of the storage bin 1. The main function of the speed-regulating motor 12 is to drive the feed in the storage bin 1 to move downward, ensuring that the feed can enter the feeding hopper 2 below in a controlled manner. The design of the speed-regulating motor 12 allows precise adjustment of its rotation speed, which directly affects the speed and flow of the feed falling.

[0054] Specifically, the speed-regulating motor 12 is connected to the internal components of the storage bin 1 through a transmission assembly, such as a gear set or a screw propulsion shaft. For example, the transmission assembly can transmit the power of the motor to the feed pushing device inside the storage bin 1, pushing the feed to continuously move towards the feeding hopper 2. When it is necessary to reduce the falling speed of the feed, the motor speed can be reduced through an external controller, so that the working frequency of the feed pushing device slows down, achieving the purpose of slowly releasing the feed. Conversely, increasing the motor speed can speed up the falling process of the feed. In this way, the feeding rate can be flexibly adjusted to meet the actual breeding needs.

[0055] Specifically, the specific parameters of the speed-regulating motor 12, such as rated voltage, current, and pre-set multiple speed levels, can be set by equipping a digital control unit. In this way, the most suitable speed setting can be selected according to the growth stage of the fish population, the feeding state, or other environmental variables, ensuring that the feed supply meets the actual situation requirements.

[0056] AsFigure 3 and Figure 4 As shown in FIG. 13, in one embodiment, a level 13 is provided on the base 5 of the aquatic feeding machine. The level 13 is used to help the user adjust the installation state of the feeding machine to keep it in a horizontal position. The base 5, as the core support structure of the entire feeding machine, bears the weight of the storage bin 1, the feeding hopper 2, the drive mechanism 4 and other components, so its stability directly affects the uniformity of the feeding of the feed. By setting the level 13, the user can intuitively observe whether the device is in the ideal working posture and make corresponding adjustments. This design provides a reliable technical support for the actual deployment of the device.

[0057] Specifically, the level 13 is composed of a bubble tube wrapped in a transparent shell and has an indicating bubble built-in. It is integrally embedded on the upper surface or side surface of the base 5, ensuring that it does not interfere with the external environment. For example, the level 13 can be firmly fixed to the corresponding part of the base 5 by adhesion, buckle connection or embedded slot. The user adjusts the posture of the feeding machine according to the bubble position offset in the level 13, combined with the leveling feet below the base 5, to finally complete the accurate installation of the device.

[0058] In actual operation, when the device is in use, the feed can be stored in the storage bin 1, and then the drive mechanism 4 is started to make the feed in the storage bin 1 move downward to the feeding hopper 2. At this time, the position of the corrugated plate adjusting rod 3 can be manually adjusted according to the growth needs of the fish population, so that the opening size of the feeding hopper 2 changes, thereby controlling the amount of feed discharged from the feeding hopper 2 each time. Under the condition that the drive mechanism 4 continues to work, the feed will be gradually fed into the pond according to the set amount, meeting the needs of aquatic farming. Finally, the base 5 is used to fix the entire feeding machine at the edge of the pond, ensuring the stable operation of the device.
