Description

Technical Field

[0001] The invention relates to the field of aquaculture technology equipment, and in particular to a high-efficiency feeding device and a feeding method for fish farming. Background Art

[0002] In modern fish farming, feed placement is one of the important links that determine the farming efficiency and fish health. The traditional manual feeding method has gradually failed to meet the needs of modern large-scale farming due to its large labor demand, low feeding efficiency, and low feed utilization rate. Automated feeding equipment has gradually replaced the traditional manual method.

[0003] However, most of the existing automatic feeding equipment mainly relies on electronic components for control and operation. Although it can improve efficiency, there are still many problems in actual use, such as high equipment maintenance cost, high failure rate, poor environmental adaptability (such as water quality, temperature changes), and strong dependence on electricity. Especially in complex water environments, electric or electronic control systems are easily affected by factors such as water vapor, humidity and electrical corrosion, resulting in equipment failure. In addition, the maintenance of electronic control equipment is complex and costly, and is not suitable for widespread use in small and medium-sized farms.

[0004] In response to these problems, it is of significant advantage to develop a feeding device with a fully mechanical structure. The fully mechanical structure does not need to rely on electronic control devices, which greatly reduces equipment downtime caused by electrical failures, and also avoids the risk of damage to electronic components in a humid environment. Through a carefully designed mechanical transmission structure, the flow of feed can be effectively controlled to prevent blockage and achieve uniform and stable feed delivery. At the same time, the mechanical structure is easy to maintain and has a long service life. It is suitable for farms of all sizes, especially those that cannot have a stable power supply or want to reduce equipment maintenance costs. Summary of the invention

[0005] The present invention aims to provide a high-efficiency feeding device and feeding method for fish farming, so as to realize automatic feeding of feed at least with a fully mechanical structure.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A high-efficiency feeding device for fish farming comprises a storage bin and a discharging hopper, wherein the storage bin and the discharging hopper are connected via a feed temporary storage box, wherein a waterwheel transmission mechanism and a linkage blocking mechanism are arranged in the feed temporary storage box; wherein the waterwheel transmission mechanism is used for controlling the discharging of the feed temporary storage box, and the linkage blocking mechanism is used for blocking the storage bin when the feed temporary storage box is discharging.

[0008] Furthermore, the waterwheel transmission mechanism includes a waterwheel, a transmission assembly and a telescopic blocking rod. The waterwheel is correspondingly connected to the two ends of the telescopic blocking rod through two sets of transmission assemblies, and the telescopic blocking rod is used to block the cover plate.

[0009] Furthermore, the transmission assembly includes a first transmission rod, a second transmission rod, an annular shaft and an inner toothed belt, the inner toothed belt is connected to the telescopic sealing rod; one end of the first transmission rod is connected to the waterwheel, and the other end is connected to the first gear, the second transmission rod is provided with a second gear meshing with the first gear, and the bottom of the second transmission rod is provided with a third gear, the third gear meshes with the inner toothed belt, and the inner toothed belt is slidably connected to the annular shaft.

[0011] Furthermore, the linkage assembly includes a connecting rope, a spring, and a pulley. The spring is connected to the inner edge of the top plate of the feed storage box, the pulley is connected to the top plate of the feed storage box, and the connecting rope connects the spring, the blocking plate, the pulley and the cover plate in sequence.

[0012] Preferably, the efficient feeding device also includes a feeding mechanism, which is connected to the storage bin.

[0013] Furthermore, the feeding mechanism includes a feeding port, a delivery pump, and a delivery pipeline which are connected in sequence, and the delivery pipeline is connected to the storage bin.

[0014] Preferably, the storage bin is provided with an observation window.

[0015] A feeding method of an efficient feeding device for fish farming, comprising: S1: The feed in the storage bin enters the waterwheel transmission mechanism in the feed temporary storage box; S2: The feed drives the waterwheel of the waterwheel transmission mechanism under the action of gravity, and the telescopic blocking rod is moved away through the transmission assembly; S3: The cover at the bottom of the feed storage box is pressed open by the feed, and the feed enters the discharge hopper and falls out; S4: When the feed is discharged, the cover plate drives the linkage blocking mechanism, and the linkage blocking mechanism cooperates with the limit groove to close the feed inlet.

[0016] Compared with the prior art, the present invention has at least one of the following improvements: 1. The feeding device of the present invention has a mechanical transmission structure of a waterwheel, a transmission assembly, a telescopic blocking rod and a cover plate. The waterwheel drives the transmission system to work under the gravity of the feed, and the transmission system drives the telescopic blocking rod to move or close the cover plate through an internal toothed belt, thereby achieving timed and quantitative feeding of feed.

This structure ensures that the feed amount is kept within the set range before each feed is put in, preventing overfeeding, while ensuring the continuity and accuracy of feed supply and improving the stability of feeding.

[0019] 4. When the feed is put in, the cover automatically closes under the elastic action of the spring, and the blocking rod is reset to the bottom of the cover, the feed port is reopened, and the next round of feeding and feeding cycle begins. This structure realizes the automatic reset function of the system, so that the feeding process can be automatically cycled, ensuring that the device continues to operate efficiently without supervision, meeting the long-term operation requirements of large-scale breeding.

[0021] 6. The storage bin of this device is equipped with a vertical strip observation window, through which the staff can monitor the feed remaining in the storage bin in real time to avoid feeding interruption caused by insufficient storage. When insufficient feed is observed, the staff can replenish feed in time through the feeding mechanism to ensure the continuous operation of the system. This design improves the efficiency of farm management and ensures the stability of feed supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "front end", "back end", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings.

Therefore, they should not be understood as limitations on the present invention.

[0025] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Embodiment 1

[0026] This embodiment provides a high-efficiency feeding device for fish farming, such as Figures 1 to 13 As shown, the device comprises a storage bin 1 and a discharge hopper 2, which are connected via a feed temporary storage box 3, and a waterwheel transmission mechanism 4 and a linkage blocking mechanism 5 are arranged in the feed temporary storage box 3. The function of the waterwheel transmission mechanism 4 is to control the discharge of the feed temporary storage box 3, and the linkage blocking mechanism 5 closes the storage bin 1 when the feed temporary storage box 3 is discharged. The device realizes automatic timed and quantitative feeding through a mechanical structure, prevents excessive feed from entering the feed temporary storage box 3, thereby ensuring the stability of feeding, effectively improving the feeding efficiency, and reducing manual intervention.

[0027] Further, refer to Figures 3 to 5Two cover plates 31 are movably provided between the feed storage box 3 and the discharge hopper 2, and the top plate of the feed storage box 3 is specifically provided with a feed inlet 32, a limit groove 33 and a linkage blocking mechanism 5. The feed inlet 32 ​​is located directly above the waterwheel transmission mechanism 4, and the feed inlet 32 ​​is connected to the storage bin 1, and the limit groove 33 is vertically connected to the feed inlet 32. The linkage blocking mechanism 5 cooperates with the limit groove 33 to block the feed inlet 32 ​​after the feed in the feed storage box 3 reaches a preset amount to prevent excessive feed from entering.

[0028] Further, refer to Figures 6 to 11 The waterwheel transmission mechanism 4 includes a waterwheel 41, a transmission assembly 42, and a telescopic blocking rod 43 horizontally arranged below the cover plate 31. The waterwheel 41 is connected to the telescopic blocking rod 43 through the transmission assembly 42. The waterwheel 41 is driven to rotate by the gravity of the feed, and the telescopic blocking rod 43 is driven to move through the transmission assembly 42. The telescopic blocking rod 43 is used to close the rotating cover plate 31 at the bottom of the feed temporary storage box 3. When the feed reaches a predetermined amount, the telescopic blocking rod 43 moves to the edge of the feed temporary storage box 3, so that the temporarily stored feed opens the cover plate 31 by gravity and flows out from the bottom of the feed temporary storage box 3. This design is based on mechanical transmission, does not require external energy, and has the advantage of energy saving.

[0029] Specifically, the transmission assembly 42 includes a first transmission rod 421, a second transmission rod 422, an annular shaft 423 and an inner toothed belt 424, and the lower end of the inner toothed belt 424 is connected to the telescopic blocking rod 43. One end of the first transmission rod 421 is connected to the waterwheel 41, and the power of the rotation of the waterwheel 41 can drive the first transmission rod 421 to rotate; the other end of the first transmission rod 421 is meshed with the second gear 4221 on the second transmission rod 422 through the first gear 4211, so that the first transmission rod 421 can drive the second transmission rod 422 to rotate; the second transmission rod 422 cooperates with the inner toothed belt 424 through the third gear 4222, and the inner toothed belt 424 is slidably connected to the annular shaft 423, so that the rotation of the second transmission rod 422 can drive the inner toothed belt 424 to slide around the inside of the annular shaft 423, and the telescopic blocking rod 43 connected below the inner toothed belt 424 is translated under the sliding of the inner toothed belt 424. This transmission structure converts the rotational energy of the waterwheel 41 into the translational movement of the telescopic blocking rod 43, thereby realizing the control of the bottom cover plate 31 of the feed temporary storage box 3, so that the feed can be automatically put in at a fixed time and quantity. Preferably, the telescopic blocking rod 43 is connected to the inner toothed belt 424 through a universal ball connector 431.

[0030] Further, refer to Fig.12 and Fig.13 The linkage blocking mechanism 5 includes a blocking plate 54, which is slidably arranged inside the limiting groove 33. Both sides of the blocking plate 54 are connected with linkage components, and two groups of linkage components are respectively connected to the two cover plates 31.

[0031] Specifically, the linkage assembly includes a connecting rope 51, a spring 52, and a pulley 53. The spring 52 is connected to the inner edge of the top plate of the feed storage box 3. The pulley 53 is connected to the top plate of the feed storage box 3. The connecting rope 51 sequentially connects the spring 52, the blocking plate 54, the pulley 53, and the cover plate 31. The pulley 53 is connected to the top plate of the feed storage box 3. Obviously, the pulley 53 itself can rotate. The pulley 53 is used to change the force transmission direction of the connecting rope 51 so that the blocking plate 54 can slide smoothly. The connecting rope 51 sequentially connects the spring 52, the blocking plate 54, the pulley 53, and the cover plate 31. The pulley 53 and the spring 52 are respectively located on both sides of the limit groove 33. When the cover plate 31 is tilted by the gravity of the feed, the cover plate 31 can pull the blocking plate 54 through the connecting rope 51 and the pulley 53, so that the blocking plate 54 can translate in the limiting groove 33 to block the feed inlet 32 ​​of the feed temporary storage box 3; when the feed gradually decreases, due to the elastic contraction of the spring 52, the side of the cover plate 31 connected to the connecting rope 51 moves upward, and the blocking plate 54 resets and translates from the blocking state until the feed inlet 32 ​​is fully opened, and the feed is stored in the feed temporary storage box 3 again.

[0032] It should be mentioned that during the discharging process, since the cover plate 31 is not in a horizontal position, the telescopic sealing rod 43 is stuck by one side of the cover plate 31 and cannot be translated back and forth. Through the transmission assembly 42, the water wheel 41 is also unable to rotate; when the cover plate 31 reaches a horizontal position under the action of the contraction of the spring 52, or is relatively horizontal and not enough to jam the telescopic sealing rod 43, the water wheel 41 can continue to rotate, and the telescopic sealing rod 43 translates to the bottom of the cover plate 31, thereby achieving the effect of blocking the cover plate 31.

[0033] Working steps: 1. Initial state Before the system is started, the storage bin 1 is filled with feed, the cover plate 31 at the bottom of the feed storage box 3 is in a closed state, the feed inlet 32 ​​is open, and the feed can flow into the feed storage box 3 through the feed inlet 32. When the feed does not enter, the water wheel 41 is in a stationary state, the telescopic blocking rod 43 is located below the cover plate 31 at the bottom of the feed storage box 3, the cover plate 31 is closed, and the feed storage box 3 is not connected to the discharge funnel 2.

[0034] 2. Feeding process Under the action of gravity, the feed flows from the storage bin 1 into the feed temporary storage box 3 through the feed inlet 32. The flow speed and flow rate of the feed are limited by the shape and size of the feed inlet 32, ensuring that the feed enters the feed temporary storage box 3 evenly and falls directly onto the waterwheel 41 just below the feed inlet 32. As the feed accumulates in the slot of the waterwheel 41 and drives the waterwheel 41 to rotate, the rotation of the waterwheel 41 drives the transmission assembly 42 downstream.

[0035] 3. Operation of the transmission assembly 42 The waterwheel 41 rotates to drive the first transmission rod 421 to rotate, and the first transmission rod 421 meshes with the second transmission rod 422 through the first gear 4211, thereby driving the second transmission rod 422 to rotate synchronously. The second transmission rod 422 is connected to the inner toothed belt 424 through the third gear 4222, and the inner toothed belt 424 drives the telescopic blocking rod 43 to move in the horizontal direction.

[0036] 4. Telescopic blocking rod 43 releases the blockage As the waterwheel 41 continues to rotate, the transmission assembly 42 continuously drives the inner toothed belt 424 to slide, and the telescopic blocking rod 43 gradually moves out of the cover plate 31 at the bottom of the feed storage box 3. When the telescopic blocking rod 43 completely moves away from the cover plate 31, the feed is pressed down by gravity and the cover plate 31 is opened, and then flows out from the discharge funnel 2 below the feed storage box 3 and is put into the breeding pond.

[0037] 5. Linkage blocking during feeding When the cover plate 31 is tilted by the gravity of the feed, the cover plate 31 can pull the blocking plate 54 through the connecting rope 51 and the pulley 53, so that the blocking plate 54 can translate in the limiting groove 33 to block the feed port 32 of the feed temporary storage box 3; when the feed gradually decreases, due to the elastic contraction of the spring 52, the side of the cover plate 31 connected to the connecting rope 51 moves upward, and the blocking plate 54 resets and translates from the blocking state until the feed port 32 is fully opened, and the above process is repeated.

[0038] In summary, the entire process enters a cyclic operation state, and the system can continue to operate efficiently without human operation. Embodiment 2

[0039] Reference Fig.14 On the basis of the first embodiment, in the second embodiment, the efficient feeding device for fish farming further comprises a feeding mechanism 6, and the feeding mechanism 6 is connected to the storage bin 1, and the feeding by mechanical structure replaces the manual feeding, thereby reducing the workload of feeding.

[0040] The design of the feeding mechanism 6 includes a feeding port 61, a delivery pump 62 and a delivery pipe 63 connected in sequence, and the delivery pipe 63 is connected to the storage bin 1. In specific applications, the delivery pump 62 can be an electric pump or a manual pump, and the delivery pump 62 is used to add feed into the storage bin 1 through the delivery pipe 63. Obviously, when electricity is used, an electric pump can be used to add and store feed in the storage bin 1, which can reduce the workload; when electricity is not used, a manual pump or direct manual work can be used to add and store feed in the storage bin 1, which is relatively more environmentally friendly. Embodiment 3

[0041] Reference Fig.15On the basis of the first or second embodiment, in the third embodiment, the storage bin 1 is provided with an observation window 11. In this embodiment, the observation window 11 is a vertically arranged strip window, which is used to observe the feed remaining inside the storage bin 1, so that the staff can replenish the feed into the storage bin 1 in time. Through the observation window 11, the staff can quickly understand the current state of the feed in the storage bin 1, avoiding the tedious operation of frequently opening the bin cover for inspection, and improving the efficiency of daily management. This design makes the management of the farm more efficient, reduces unnecessary operation links, and can save labor costs, especially in the daily management of large-scale farms.

[0042] Specific application cases: In the daily management of fish farms, the automatic feeding device of the present invention can significantly improve the efficiency of feed delivery and reduce manual intervention. The efficient feeding device for fish farming provided by the present invention relies on a mechanical transmission structure to achieve automatic feeding of a fixed amount of time, thereby ensuring the reasonable delivery of fish feed and reducing labor costs. When used, the device can be installed above the breeding pond, and the storage bin 1 is connected to the external feeding system through the feeding mechanism 6 to ensure the continuous supply of feed.

[0043] First, the staff transports the feed to the storage bin 1 through the feeding mechanism 6. The capacity of the storage bin 1 is sufficient to meet the long-term feeding needs. The feed enters the feed storage box 3 through the feed inlet 32 ​​from the bottom of the storage bin 1, and the feed gradually falls onto the waterwheel 41. As the feed accumulates, the waterwheel 41 starts to rotate under the action of gravity, driving the transmission component 42 to work. The transmission component 42 converts the rotational energy of the waterwheel 41 into translation control of the telescopic blocking rod 43 through gears, transmission rods and internal toothed belts 424. The telescopic blocking rod 43 gradually translates away from under the cover plate 31. Under the action of the gravity of the feed, the cover plate 31 at the bottom of the feed storage box 3 opens, and the feed is automatically delivered to the breeding pond through the discharge funnel 2.

[0044] During the feeding process, as the amount of feed changes, the linkage blocking mechanism 5 controls the opening and closing of the feed port 32, which can ensure that the amount of feed in the feed temporary storage box 3 is within the set range during the feeding process to avoid overfeeding. After each feeding, due to the reduction of the amount of feed in the feed temporary storage box 3, the system will restore the initial state through the spring 52, and the cover plate 31 will be closed under the traction of the spring 52, while the feed port 32 will be reopened, and the waterwheel 41 will continue to rotate to cause the telescopic blocking rod 43 to return to the bottom of the cover plate 31, and the system will enter the next round of feeding cycle.

[0045] When the feed in the feed storage bin 1 is close to being exhausted, the observation window 11 enables the staff to monitor the remaining feed in real time, and the staff can add feed through the feeding port 61 according to the observation results. The feeding process can be carried out by an electric pump or a manual pump, and the specific method can be selected according to the actual situation. If an electric pump is used, the feed will automatically enter the storage bin 1 through the conveying pipeline; in the absence of electricity, the staff can use a manual pump or directly add feed manually.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
