Description

Technical Field

[0001] The invention relates to the technical field of lobster breeding, and in particular to an automatic crayfish catching device suitable for rice fields. Background Art

[0002] Crayfish are an omnivorous, freshwater, commercial shrimp with fast growth and strong adaptability. They have become an important economic aquaculture species in China. Their high protein content and rich meat containing trace elements such as zinc, iodine, and selenium make them popular among consumers. The fishing season is a key step in the aquaculture process in ponds, lakes, and other waters. Efficient fishing methods have a significant impact on the economic benefits of aquaculture, so suitable fishing equipment is needed to achieve large-scale capture of crayfish.

[0003] Currently, a Chinese patent with the publication number "CN216164561U" discloses a device for catching crayfish conveniently. The device mainly includes a fishing tube, a shrimp feeding box and other structures. The fishing tube has a regular hexagonal cross-section when viewed from above, with openings on all six sides connected to the shrimp feeding box. A first shrimp feeding channel and a second shrimp feeding channel are respectively provided on both sides of the shrimp feeding box. A shrimp storage chamber is formed inside the fishing tube, and a bait protection net cylinder is provided in the middle of the lower side. The device reduces the escape rate of crayfish through the double shrimp feeding channel design, and uses the bait protection net cylinder to prevent the bait from being eaten, thereby improving the efficiency of shrimp catching to a certain extent.

[0004] However, the device still has significant defects in actual application. First, the existing device requires manual operation of the entire process of placing, recovering and replacing the fishing device. In crayfish-dense farms, the fishing devices need to be placed one by one in the rice field breeding area and wait for a long time to be trapped. When the device is full, it needs to be inspected and collected manually on a regular basis, and then released again. This process requires a lot of manpower, especially in large-scale breeding scenarios. The frequency of manual travel back and forth between rice fields is high and the labor intensity is high. In addition, the water environment such as breeding rice fields is usually muddy and slippery. Manual operation is not only time-consuming and labor-intensive, but may also cause disturbances to the breeding environment, such as trampling on rice seedlings and stirring up water bodies. As labor costs rise, the economic efficiency of the fishing mode that relies on manual labor gradually declines. At the same time, the existing device has a fixed structure and is difficult to adapt to different water depths, terrains or breeding modes such as the differences between ponds, lakes and rice fields, and cannot meet diverse fishing needs. It can be seen that the existing technology has certain defects and deficiencies, so it needs to be improved and designed. Summary of the Invention

The third motor 6413 is fixedly installed on the side of the fixed arm 6411 away from the vertical rail 631. The output end of the third motor 6413 passes through the fixed arm 6411 and is fixedly installed with a synchronous wheel 6414. The side of the fixed arm 6411 away from the third motor 6413 is also rotatably connected to the synchronous wheel 6414. The synchronous wheels 6414 are connected by a synchronous belt 6415. The outer end of the connecting shaft 6412 is fixedly connected to the side of the synchronous wheel 6414 at the bottom close to the third motor 6413, carrying Group 642 includes a fishing box 6421, which is fixedly installed on the outer end of the connecting shaft 6412.

The side of the fixed frame 62 away from the vertical rail 631 is fixedly connected to a supporting rail 65. The inner part of the rail 65 is slidably connected to the supporting block 66, and a supporting arm 67 is fixedly installed on the side of the supporting block 66 close to the fishing box 6421. The outer end of the supporting arm 67 is rotatably connected to the side of the fishing box 6421 away from the connecting shaft 6412. During the application of this device, when the driving group 641 and the carrying group 642 work together, the third motor 6413 is started and drives the synchronous wheel 6414 to rotate, and drives the bottom synchronous wheel 6414 and the connecting shaft 6412 to rotate through the synchronous belt 6415, thereby causing the fishing box 6421 fixed at the outer end of the connecting shaft 6412 to flip around the axis of the connecting shaft 6412. When the fishing box 6421 is in a horizontal state, the inclined climbing net 6422 is immersed in water at an inclined angle toward the storage mechanism 7, and the bait in the bait net box 6423 is The bait is sealed and preserved by the magnetic plate 6424, and the fishy smell it emits diffuses through the water body to attract crayfish to climb into the fishing box 6421 in one direction along the inclined climbing net 6422. After the fishing is completed, the third motor 6413 drives the synchronous wheel 6414 in reverse to make the fishing box 6421 flip backward. At this time, the guide bucket 6425 is aligned with the unloading port of the storage mechanism 7. The crayfish slides from the guide bucket 6425 into the storage frame 75 as the fishing box 6421 tilts. The supporting rail 65 and the supporting block 66 form a sliding guide structure. One end of the supporting arm 67 is connected to the supporting block 66 and the other end is rotatably connected to the fishing box 6421, providing support force during the flipping process of the fishing box 6421 to avoid shaking or deviation of the fishing box 6421 due to gravity, thereby ensuring smooth and reliable unloading.At the same time, it helps maintain the vertical posture of the fishing box 6421 when entering and exiting the water, thereby improving the overall structural stability.

[0035] See also Figure 1-Figure 7 The fishing mechanism 6 includes a hanging plate 61, which is fixedly mounted on the bottom of the slider 33. A fixing frame 62 is fixedly mounted on one side of the bottom of the hanging plate 61. An adjusting component 63 is fixedly mounted on one end of the fixing frame 62. A fishing component 64 is provided at the lower end of the adjusting component 63. The adjusting component 63 includes a vertical rail 631, which is fixedly mounted on one end of the fixing frame 62. A second motor 632 is fixedly connected to the top of the vertical rail 631. The output end of the second motor 632 passes through the vertical rail 631. A screw rod 633 is fixedly connected, and the screw rod 633 is rotatably connected to the inside of the vertical rail 631. The outer surface of the screw rod 633 is threadedly connected to a sliding block 634. The sliding block 634 is slidably connected to the inside of the vertical rail 631. One side of the sliding block 634 is connected to the fishing component 64. The fishing component 64 includes a driving group 641 and a bearing group 642. The driving group 641 is fixedly connected to the outside of the sliding block 634, and the bearing group 642 is fixedly installed on the outside of the driving group 641. During use, when it is necessary to carry out crayfish fishing operations, the second motor 632 is started to drive the screw rod 633 inside the vertical rail 631 to rotate. Since the screw rod 633 is threadedly connected to the sliding block 634, and the sliding block 634 is restricted by the vertical rail 631 to only move linearly, the rotation of the screw rod 633 is converted into the vertical lifting of the sliding block 634 in the vertical rail 631. The driving group 641 connected to the outside of the sliding block 634 moves synchronously, thereby driving the carrying group 642 to enter and exit the water. Action, when the carrying group 642 descends into the water of the rice field, the bait placed inside it emits a fishy smell to attract crayfish, and the crayfish enter the carrying group 642 through the inclined climbing net 6422 box. After the fishing is completed, the second motor 632 reverses, driving the screw rod 633 to drive the sliding block 634 to move upward, so that the carrying group 642 is out of the water. During the whole process, the vertical rail 631 provides guidance and support for the sliding block 634, ensuring the stable operation of the fishing component 64 and realizing the efficient trapping and collection of crayfish.

[0036] See also Figure 1-Figure 5The storage mechanism 7 includes a support frame 71, which is fixedly mounted on the side of the top of the base 1 away from the square groove 4. The fourth motor 72 is fixedly mounted on the bottom of the support frame 71, and the output end of the fourth motor 72 passes through the fixed disk and is fixedly mounted with a turntable 73. The top of the turntable 73 is fixedly mounted with a placement seat 74 arranged in a ring at equal intervals. A storage frame 75 is placed inside the placement seat 74. A mounting base 76 is fixedly mounted on the middle part of the side of the top of the base 1 away from the square groove 4. A top plate 77 is fixedly mounted on the top of the mounting base 76.

The shaft ends of the first motor 342, the second motor 632, the third motor 6413 and the fourth motor 72 are all provided with encoders. During the use of this device, when the storage mechanism 7 is working, the fourth motor 7 The turntable 73 is driven to rotate, and the placement seat 74 on the top of the turntable 73 rotates synchronously with the turntable 73, so that the empty storage frame 75 rotates to the unloading position below the fishing mechanism 6 in sequence. When the fishing box 6421 is turned over to unload, the crayfish passes through the guide bucket 6425 and the reserved groove 78 and falls into the storage frame 75. The fully loaded storage frame 75 continues to rotate with the turntable 73 and moves to the bottom of the top plate 77. The top plate 77 covers the top of the storage frame 75.

At the same time, the action sequence of the fishing mechanism 6 and the storage mechanism 7 is coordinated to realize the automated flow of crayfish from fishing to storage, thereby improving the consistency and efficiency of the overall operation.

[0037] See also Figure 1-Figure 4 and Figure 8, the adjustment displacement assembly 34 includes a fixed plate 341, the fixed plate 341 is fixedly connected to the top of the slider 33, and a first motor 342 is fixedly installed on one side of the fixed plate 341. The output end of the first motor 342 passes through the fixed plate 341 and is fixedly installed with a gear 343. The gear 343 is meshed with the rack 32. During the use of this device, when the adjustment displacement assembly 34 of the transverse movement mechanism 3 is working, the first motor 342 is fixedly installed on one side of the fixed plate 341, and its output end drives the gear 343 to rotate. Since the gear 343 is meshed with the rack 32 fixed on the top of the top rail 31, the rotation of the gear 343 The movement is converted into linear motion, driving the fixed plate 341 and the slider 33 connected thereto to slide inside the top rail 31 along the direction of the rack 32. The bottom of the slider 33 is connected to the fishing mechanism 6. Therefore, the lateral movement of the slider 33 can accurately adjust the position of the fishing mechanism 6 under the top rail 31, so that it can move back and forth between the square groove 4 area above the base 1 and the storage mechanism 7. By controlling the forward and reverse rotation and the number of revolutions of the first motor 342, the meshing transmission distance between the gear 343 and the rack 32 can be accurately controlled to realize the positioning and transfer of the fishing mechanism 6, thereby ensuring the automated connection and position accuracy of the crayfish fishing and transportation links.

[0038] The working principle of the present invention is: in the technical solution of the present invention, the coordinated design of the fishing mechanism 6 and the transverse movement mechanism 3 provides a mechanical basis for automated fishing. The specific operation process is as follows: by starting the transverse movement mechanism 3, its adjustment displacement component 34 can drive the fishing mechanism 6 to move smoothly along the transverse track, so that the fishing mechanism 6 is accurately positioned in the square trough 4 area of the rice field water area. The base 1 is fixed to the side of the rice field to provide stable support for the overall structure. When the fishing mechanism 6 reaches the specified position, the second motor 632 is started, and its output shaft drives the screw rod 633 to rotate. Since the threads at both ends of the screw rod 633 rotate in opposite directions, the slider 33 makes a vertical linear motion on the screw rod 633, thereby driving the fixed arm 6411 to rise and fall synchronously. The fixed arm 6411 is rigidly connected to the fishing box 6421 to achieve the lowering of the fishing box 6421 in the water body. Sinking or lifting, when in use, the bait is placed in the bait net box 6423, and the magnetic plate 6424 fixes the bait net box 6423 by magnetic attraction to prevent crayfish from entering the net box to swallow the bait. The fishy smell emitted by the bait spreads through the water body, attracting crayfish to gather, and the crayfish climb along the inclined climbing net box to the fishing box 6421. The inclined structure utilizes the crayfish's habit of climbing towards bait and forms a one-way entry channel to effectively prevent them from escaping. After the fishing operation is completed, the second motor 632 is started again to drive the screw rod 633 to rotate in the opposite direction, and the slider 33 drives the fishing box 6421 out of the water to facilitate subsequent collection operations. The supporting rail 65 and the supporting block 66 form a sliding guide structure. Under the connection of the supporting arm 67, it provides stability support for the lifting process of the fishing box 6421, reduces shaking, and ensures the reliable operation of the fishing mechanism 6;

[0039] The linkage mechanism of the fishing mechanism 6, the transverse movement mechanism 3 and the storage mechanism 7 further improves the automated operation capability of the device. After the fishing box 6421 completes fishing and is lifted above the water surface, the first motor 342 is started, and the driving gear 343 rotates. The gear 343 engages with the rack 32 for transmission, driving the slider 33 to slide horizontally in the top rail 31, and the fishing box 6421 is moved to the top of the storage frame 75. At this time, the third motor 6413 is started, and the synchronous wheel 6414 and the synchronous belt 6415 are driven to rotate the connecting shaft 6412. The connecting shaft 6412 is connected to the bottom shaft of the fishing box 6421 to realize the flipping action of the fishing box 6421. When the fishing box 6421 flips to the rear side, its tail The guide bucket 6425 is aligned with the rotating groove on the side of the storage frame 75, and the crayfish in the box automatically fall into the storage frame 75 through the reserved groove 78 to complete the automatic unloading. After the unloading is completed, the first motor 342 and the second motor 632 are operated in coordination, and the fishing box 6421 can be sunk back into the water body of the rice field to enter the next round of fishing cycle. In the storage link, the fourth motor 72 drives the turntable 73 to rotate, and the storage frame 75 on the top of the turntable 73 rotates with the turntable 73. When a storage frame 75 is full, it can be transferred to the bottom of the top plate 77 by rotating the turntable 73. The top plate 77 covers the top of the storage frame 75. Its ventilation slot 79 is designed to ensure air circulation, and the protective net 710 prevents the crayfish from escaping from the slot.

[0040] The device has built an intelligent control system by integrating an encoder and a timing module. The encoder monitors the operating parameters of each motor such as speed and displacement in real time, and feeds the data back to the control module. The control module accurately adjusts the start and stop and operating status of the motor through a preset algorithm, thereby realizing precise control of the displacement, flipping and conversion of the fishing box 6421 and the storage frame 75. The timing module supports users to set the fishing cycle and collection time. For example, it can be set to automatically start the sinking, trapping, lifting and unloading processes of the fishing mechanism 6 every 2 hours without manual intervention. This automated control mode significantly reduces the intensity of manual labor and the impact of the muddy environment of the rice fields on operators, while avoiding the loss of fishing efficiency due to untimely manual inspections. Through the combination of mechanical structure innovation and intelligent control, the present invention realizes the full process automation of crayfish fishing, transportation and storage, and improves the fishing efficiency and management level in large-scale breeding scenarios.
