Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to an automatic feeding device for bait boxes in crab traps. Background Technology

[0002] In modern marine fisheries and aquaculture, crabs, as an important economic aquatic product, occupy a significant position in the global market. To improve crab harvesting efficiency and quality, the design and application of crab traps are constantly being improved. Among these, the bait box, as a key component of the crab trap, has a direct impact on the harvesting effect due to its design and usage. Currently, some bait boxes, such as those included in the instruction manual... Figure 1 As shown, a specific feeding method is used, in which chopped bait is placed into the bait box using a rod-shaped tool. The specific operation process of this method includes: First, workers need to thaw the frozen bait and chop it into appropriately sized chunks or granules. Then, using a specially designed rod-shaped tool, an appropriate amount of bait is taken out from the container containing the chopped bait and accurately placed into the predetermined position in the bait box to ensure that the bait is evenly distributed throughout the box. Finally, the loaded bait box is fixed to the designated position inside the crab trap, ready to be lowered into the sea along with the crab trap for fishing operations.

[0003] While this rod-based feeding method simplifies the process to some extent, it still relies heavily on manual intervention. Workers need to manually thaw and cut the bait, then use the rod to fill the bait boxes one by one. The process is quite complex, and to ensure the freshness and even distribution of the bait, workers may need to repeat the above actions multiple times to ensure that there is enough bait in every corner. During large-scale fishing, frequent operations increase the workload of workers, and each time the quantity and position of the bait need to be precisely controlled manually, which is not only time-consuming but also prone to errors, affecting the fishing results. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for bait boxes in crab traps, which can reduce manual operation and improve feeding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a bait box in a crab trap, comprising a frame, and further comprising,

[0006] A receiving tray is fixed on the frame. The receiving tray has a feeding station and a push rod for pushing the bait box toward the feeding station can also be rotatably provided on the receiving tray.

[0007] A guide bracket is fixed inside the frame. At least one horizontally distributed feeding channel is provided inside the guide bracket. A feeding channel connected to the feeding channel is also vertically provided on the guide bracket. A pusher rod is slidably provided in each feeding channel. The pusher rod is used to deliver the bait in the feeding channel to the bait box located at the loading station.

[0008] A push plate is fixed to one end of the push rod, and a return spring is provided between the push plate and the guide bracket, and the return spring is sleeved on the push rod;

[0009] A linkage mechanism, located within the frame, is used to drive the push rod to rotate when the push plate is pushed forward toward the loading station.

[0010] Preferably, the linkage mechanism includes a drive motor, an eccentric wheel, a first rotating shaft, a second rotating shaft, a first pulley, a second pulley, and a synchronous belt. The drive motor is fixed inside the frame. The first rotating shaft is horizontally rotatable inside the frame. The eccentric wheel is fixed on the first rotating shaft and is used to push the push plate to move towards the loading station. The drive motor is used to drive the first rotating shaft to rotate. The second rotating shaft is vertically rotatable inside the frame. The first pulley is coaxially fixed to the lower end of the second rotating shaft. The push rod is rotatably disposed at the center of the receiving tray through a third rotating shaft. The second pulley is coaxially fixed to the lower end of the third rotating shaft. The synchronous belt is wound between the first pulley and the second pulley. The first rotating shaft and the second rotating shaft are connected by a gear assembly.

[0011] Preferably, a first gear is coaxially fixed on the output shaft of the drive motor, and a second gear is coaxially fixed at one end of the first rotating shaft, with the first gear meshing with the second gear.

[0012] Preferably, the gear assembly includes a third gear, a fourth gear, a first bevel gear, and a second bevel gear. The third gear is rotatably disposed within the frame and meshes with the second gear and the fourth gear, respectively. A fourth rotating shaft is coaxially fixed to the fourth gear. The fourth rotating shaft is horizontally rotatably disposed within the frame. The first bevel gear is coaxially fixed to one end of the fourth rotating shaft. The second bevel gear is coaxially fixed to the upper end of the second rotating shaft and meshes with the first bevel gear.

[0013] Preferably, a fixing rod is fixed to the upper end of the push plate, and a bearing for contacting the eccentric wheel is installed on the fixing rod.

[0014] Preferably, a fifth rotating shaft is also provided inside the frame. The fifth rotating shaft is circumferentially evenly provided with a plurality of paddles. The paddles are located within the loading station, and a transfer space for accommodating a bait box is formed between adjacent paddles. The transfer space is used to connect with the feeding channel and to drive the bait box away from the loading station after the bait is loaded. A drive gear is also coaxially fixed on the fifth rotating shaft, and a sector gear is coaxially fixed on the fourth rotating shaft. The sector gear is meshed with the drive gear.

[0015] Preferably, the bottom of the frame is provided with a feeding port, which is located below the paddle.

The guide bracket has at least one feeding channel horizontally and a feeding channel connected to the feeding channel vertically. This structure realizes efficient delivery of bait from different directions. The pusher rod, which is slidably set in the feeding channel, can accurately deliver the bait into the bait box located at the loading station through the cooperation of the push plate and the return spring. The return spring ensures that the pusher rod can quickly return to its original position after completing its work, thus improving the continuous operation capability of the device.

[0017] In addition, the linkage mechanism further optimizes the overall efficiency of the system. While pushing the push plate forward, the linkage mechanism can simultaneously drive the push rod to rotate, completing the position adjustment of the bait box and the filling of bait. In this way, the entire device achieves automated and coordinated operation, reducing the need for human intervention. Its compact design occupies little space, and while improving the accuracy and speed of filling, it also effectively reduces labor intensity, making it suitable for the high-efficiency operation requirements of large-scale crab fishing.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example 1: As shown in the figure, an automatic feeding device for bait boxes in crab traps includes a frame 1, and further includes...

[0026] The receiving tray 2 is fixed on the frame 1. The receiving tray 2 has a feeding station 3. The receiving tray 2 is also rotatably equipped with a push rod 4 for pushing the bait box toward the feeding station 3.

[0027] The guide bracket 5 is fixed inside the frame 1. At least one horizontally distributed feeding channel 6 is provided inside the guide bracket 5. A feeding channel 7 connected to the feeding channel 6 is also vertically provided on the guide bracket 5. A pusher rod 8 is also slidably provided in each feeding channel 6. The pusher rod 8 is used to send the bait in the feeding channel 7 to the bait box located on the loading station 3.

[0028] Push plate 9 is fixed to one end of push rod 8. A return spring 10 is provided between push plate 9 and guide bracket 5, and the return spring 10 is sleeved on push rod 8.

[0029] The linkage mechanism 11 is installed inside the frame 1 and is used to drive the push rod 4 to rotate when the push plate 9 moves forward toward the loading station 3.

[0030] Example 2: As shown in the figure, unlike Example 1, the linkage mechanism 11 includes a drive motor 12, an eccentric wheel 13, a first rotating shaft 14, a second rotating shaft 15, a first pulley 16, a second pulley 17, and a synchronous belt 18. The drive motor 12 is fixed inside the frame 1. The first rotating shaft 14 is horizontally rotatable inside the frame 1. The eccentric wheel 13 is fixed on the first rotating shaft 14 and is used to push the push plate 9 to move towards the loading station 3. The drive motor 12 is used to drive the first rotating shaft 14 to rotate. The second rotating shaft 15 is vertically rotatable inside the frame 1. The first pulley 16 is coaxially fixed at the lower end of the second rotating shaft 15. The push rod 4 is rotatably set at the center of the receiving tray 2 through the third rotating shaft 19. The second pulley 17 is coaxially fixed at the lower end of the third rotating shaft 19. The synchronous belt 18 is wound between the first pulley 16 and the second pulley 17. The first rotating shaft 14 and the second rotating shaft 15 are connected by a gear assembly 22.

[0031] In the above structure, the drive motor 12 is fixed inside the frame 1 and serves as the power source for the entire system. It drives the first rotating shaft 14 to rotate horizontally. An eccentric wheel 13 is fixed on the first rotating shaft 14. When the eccentric wheel 13 rotates with the first rotating shaft 14, it pushes the push plate 9 forward through its eccentric structure, thereby driving the push rod 8 to accurately feed the bait from the feeding channel 7 into the bait box located at the loading station 3.

[0032] Meanwhile, the first rotating shaft 14 and the second rotating shaft 15 are connected by a gear assembly 22 to ensure efficient power transmission and synchronous operation. The second rotating shaft 15 is vertically rotatable and has a first pulley 16 fixed at its lower end. Through the synchronous belt 18, the first pulley 16 transmits power to the second pulley 17, which is coaxially fixed on the third rotating shaft 19. The third rotating shaft 19 is connected to the push rod 4, so that the push rod 4 can rotate synchronously, thereby pushing the bait box to move along the trajectory of the receiving plate 2 to the loading station 3.

[0033] The main advantage of this design lies in its high degree of automation and coordination. By driving multiple rotating shafts and their connecting components through the drive motor 12, the entire system can achieve synchronous completion of bait filling and bait box position adjustment, reducing tedious manual operations. In addition, the combined design of the gear assembly 22, pulleys and timing belt 18 ensures efficient power transmission and stable movement, while avoiding energy waste. The application of the eccentric wheel 13 makes the movement of the pusher plate 9 more stable and precise, improving the filling accuracy.

[0034] Preferably, a first gear 20 is coaxially fixed on the output shaft of the drive motor 12, and a second gear 21 is coaxially fixed at one end of the first rotating shaft 14, with the first gear 20 meshing with the second gear 21.

[0035] In the above structure, when the drive motor 12 starts, the first gear 20 rotates and drives the second gear 21 to rotate through gear meshing, thereby driving the first rotating shaft 14 to rotate. The diameter of the first gear 20 is smaller, and a transmission ratio is generated relative to the diameter of the second gear 21. This structure realizes the reduction of rotational speed and the increase of torque, enabling the entire linkage mechanism 11 to complete the action of the push rod 8 and the movement of the bait box with stronger power and more precise speed.

[0036] Example 3: As shown in the figure, unlike Example 2, the gear assembly 22 includes a third gear 23, a fourth gear 24, a first bevel gear 25, and a second bevel gear 26. The third gear 23 is rotatably mounted in the frame 1 and meshes with the second gear 21 and the fourth gear 24 respectively. A fourth rotating shaft 27 is coaxially fixed on the fourth gear 24. The fourth rotating shaft 27 is horizontally rotatably mounted in the frame 1. The first bevel gear 25 is coaxially fixed at one end of the fourth rotating shaft 27. The second bevel gear 26 is coaxially fixed at the upper end of the second rotating shaft 15 and meshes with the first bevel gear 25.

[0037] In the above structure, the gear assembly 22 consists of a third gear 23, a fourth gear 24, a first bevel gear 25, and a second bevel gear 26. The drive motor 12 drives the third gear 23 to rotate through the first gear 20 and the second gear 21. The third gear 23 drives the fourth gear 24 to rotate through meshing. The fourth gear 24 is coaxially fixed to a fourth rotating shaft 27. The fourth rotating shaft 27 is horizontally set and can rotate freely. At one end of the fourth rotating shaft 27, the first bevel gear 25 is coaxially fixed. The first bevel gear 25 meshes with the second bevel gear 26 on the vertically set second rotating shaft 15. Through the meshing of this pair of bevel gears, the power is transmitted from the horizontal rotation of the fourth rotating shaft 27 to the vertical rotation of the second rotating shaft 15, thereby driving the rotation of the first pulley 16, which is coaxially fixed to the second rotating shaft 15. Then, through the synchronous belt 18 and the second pulley 17, the push rod 4 is driven to rotate, so that the movement of the bait box can be synchronized.

[0038] This component features a compact structural layout and modular design. Through the flexible combination of gears and shafts, the power transmission path can be adjusted as needed, enhancing the system's adaptability.

[0039] Preferably, a fixing rod 28 is fixed to the upper end of the push plate 9, and a bearing 29 for contacting the eccentric wheel 13 is installed on the fixing rod 28.

[0040] In the above structure, a fixed rod 28 is fixed to the upper end of the push plate 9. The bearing 29 installed on the fixed rod 28 is in direct contact with the eccentric wheel 13. When the eccentric wheel 13 rotates with the first rotating shaft 14, its eccentric structure drives the bearing 29 to move accordingly. The rolling action of the bearing 29 can smoothly convert the rotational motion of the eccentric wheel 13 into the linear reciprocating motion of the push plate 9, thereby driving the push rod 8 to send the bait from the feeding channel 7 into the bait box. This design significantly reduces the frictional resistance between the eccentric wheel 13 and the fixed rod 28 through the rolling contact of the bearing 29, while improving the smoothness and efficiency of the push plate 9's movement.

[0041] Preferably, a fifth rotating shaft 30 is also provided inside the frame 1. A plurality of paddles 31 are evenly arranged circumferentially on the fifth rotating shaft 30. The paddles 31 are located in the loading station 3, and a transfer space for accommodating a bait box is formed between adjacent paddles 31. The transfer space is used to connect with the feeding channel 7 and to drive the bait box away from the loading station 3 after the bait is loaded. A drive gear 32 is also coaxially fixed on the fifth rotating shaft 30, and a sector gear 33 is also coaxially fixed on the fourth rotating shaft 27. The sector gear 33 is meshed with the drive gear 32.

[0042] In the above structure, multiple paddles 31 are evenly arranged circumferentially on the fifth rotating shaft 30. The transfer space formed between adjacent paddles 31 can just accommodate a bait box. The fifth rotating shaft 30 is installed in the frame 1. Its rotation can cause the paddles 31 to send the bait box into the loading station 3 in sequence. After loading, it continues to push the bait box away from the loading station 3, completing the entire loading and transfer process of the bait box. When the transfer space is connected with the feeding channel 7, the push rod 8 sends the bait from the feeding channel 7 into the bait box. After loading, the fifth rotating shaft 30 rotates. Through the action of the sector gear 33 and the drive gear 32, the paddles 31 drive the bait box out, providing space for the next loading.

[0043] This design significantly improves the automation level of the device, enabling precise loading and movement of the bait box without manual intervention, thus improving work efficiency. The even distribution of the paddles 31 ensures accurate positioning of the space during each transfer, allowing the bait box to be fully aligned with the feeding channel 7, avoiding misalignment or bait waste, and guaranteeing the accuracy of the loading process.

[0044] Preferably, the bottom of the frame 1 is provided with a feeding port 34, which is located below the paddle 31.

[0045] In the above structure, the feeding port 34 is located below the lever 31. When the lever 31 rotates and rotates the bait box after it has been filled by a certain angle, the bait box falls naturally through the feeding port 34 under the action of gravity, thereby completing the transfer operation after filling. The design of the feeding port 34 enables the bait box to fall quickly and accurately into the collection device or transportation channel below after filling, which provides convenience for the subsequent distribution or use of the bait box.

[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
