Description
Technical Field
[0001] This utility model relates to the field of crayfish breeding technology, and in particular to a zoned breeding structure for crayfish in rice paddies. Background Technology
[0002] Crayfish farming refers to completely separating the seedling raising and rearing stages in the aquaculture process to improve the quality and efficiency of the farming.
[0003] In the current crayfish farming process, when staff need to harvest the farmed crayfish, they need to use external tools, which is difficult to do and consumes a lot of time. Utility Model Content
[0004] This utility model discloses a zoned aquaculture structure for crayfish in rice paddies, aiming to solve the technical problem that in the existing crayfish farming process, when workers need to harvest the farmed crayfish, they need to use external tools to harvest them, which is difficult to operate and consumes a lot of time.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A crayfish breeding and aquaculture structure in a paddy field includes a frame with mounting rods slidably connected to the four corners of the top of the frame. Insert plates are inserted into the inner sides of the mounting rods. The structure also includes a catching mechanism: the catching mechanism includes a net bag disposed inside the frame, with pull ropes installed at both ends of the net bag. One end of each pull rope is fitted with a limiting tube. A fixing component for assisting catching is fixedly connected to the top of the insert plate. A spring plate is installed inside the limiting tube, and a locking cylinder is fixedly connected to the top of the spring plate. A pressing button is fixedly connected to the top of the locking cylinder. Finally, a user mechanism is disposed at the top of the frame and is used to assist workers in quickly assembling and disassembling the aquaculture equipment.
[0007] By setting up a catching mechanism, when workers catch crayfish, they first press down on a button, which causes the bottom-fixed clamp to slide down. As the clamp presses against the spring plate, the through groove on the outside of the clamp and the limiting cylinder aligns, allowing the pull rope to be pulled. As the pull rope is pulled, the net is lifted, allowing the crayfish raised in the frame to be caught.
[0008] In a preferred embodiment, the device includes fixed frames disposed at both ends of the top of the frame, each end of the fixed frame having a slot, a roller being rotatably connected inside the slot, a protective net being fixedly connected to the inner side of the mounting rod, a rotating cylinder being rotatably connected to the top end of the mounting rod, a fixed rod being rotatably connected inside the rotating cylinder, a connecting component for auxiliary installation being fixedly connected to the top end of the fixed rod, and a plug rod being threadedly connected to the bottom end of the fixed rod.
[0009] By setting up the operating mechanism, the user can simultaneously pull the two sets of mounting rods that are slidably connected at the top of the frame. This allows the two sets of mounting rods to slide and stretch the protective net, causing the protective net to retract and expand outside the roller and form a barrier on both sides of the frame. At the same time, by rotating the rotating drum connected to the top of the mounting rod clockwise, the rotating drum will cause the fixed rod to rotate inside the mounting rod. This rotation of the fixed rod will cause the threaded insertion rod at the bottom to rotate and insert into the soil of the aquaculture area.
[0010] In a preferred embodiment, the connecting assembly includes a fixed cylinder disposed at the top end of the fixed rod, the fixed cylinder having a toothed groove on its outer side and the rotating cylinder having a toothed pattern on its inner side, and the rotating cylinder and the fixed cylinder being meshed together.
[0011] The outer surface of the fixing rod is threaded, and the inside of the insertion rod is threaded. The fixing rod and the insertion rod are arranged on the same central axis.
[0012] By setting up connecting components, the rotating drum can drive the fixed drum to rotate simultaneously.
[0013] In a preferred embodiment, the outer side of the roller is provided with a winding groove, one end of the protective net is wound into the winding groove, and the fixing component includes a through cylinder disposed at the top of the insert plate, and both ends of the pull rope are sleeved inside the through cylinder through the clamping sleeve.
[0014] By setting a fixing component, the pull rope can be pulled out along the trajectory of the through-tube.
[0015] This utility model discloses a zoned aquaculture structure for crayfish breeding in rice paddies, which has the following beneficial effects.
[0016] Firstly, by setting up a catching mechanism, when staff are catching crayfish, pressing down on the button causes the bottom-fixed connecting cylinder to slide down, and as the cylinder squeezes the spring plate, the through groove on the outside of the cylinder and the limiting cylinder aligns, thereby pulling the rope. As the rope is pulled, the net is lifted, which can catch the crayfish raised in the frame. This can assist in catching crayfish and improve the catching effect.
[0017] Secondly, by setting up a user mechanism, users can simultaneously pull the two sets of mounting rods that are slidably connected at the top of the frame. This allows the protective net to be stretched during the sliding process, enabling the net to be rolled up and down outside the roller and forming a barrier on both sides of the frame. At the same time, by rotating the rotating drum connected to the top of the mounting rod clockwise, the rotating drum causes the fixed rod to rotate inside the mounting rod. This rotation of the fixed rod causes the threaded insertion rod at the bottom to rotate and insert into the soil of the aquaculture area. This can assist staff in quickly assembling and disassembling the aquaculture device. Attached Figure Description

[0026] The present invention discloses a crayfish breeding and farming structure in a paddy field. It mainly applies to the existing crayfish breeding process, where workers need to use external tools to catch the crayfish when they need to harvest them.
[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A crayfish breeding and aquaculture structure in a paddy field includes a frame 1, with mounting rods slidably connected to the four corners of the top of the frame 1. Insert plates 3 are inserted into the inner sides of the mounting rods 2. The structure also includes a catching mechanism: the catching mechanism includes a net 17 installed inside the frame 1, with pull ropes 9 installed at both ends of the net 17. One end of the pull rope 9 is fitted with a limiting cylinder 10. A fixing component for assisting catching is fixedly connected to the top of the insert plate 3. A spring plate 16 is installed inside the limiting cylinder 10, and a clamping cylinder 15 is fixedly connected to the top of the spring plate 16. A pressing button 11 is fixedly connected to the top of the clamping cylinder 15. Finally, a user mechanism is located at the top of the frame 1 and is used to assist workers in quickly assembling and disassembling the aquaculture equipment.
[0028] In this solution, when staff are raising crayfish or catching crayfish, firstly, by pressing down button 11, the bottom-fixed connecting cylinder 15 slides down, and as the cylinder 15 squeezes the spring plate 16, the cylinder 15 and the through slot on the outside of the limiting cylinder 10 are aligned, thereby pulling the pull rope 9, which slides inside the through cylinder 8. As the pull rope 9 is pulled, the net 17 is lifted, and the crayfish raised in the frame 1 can be caught. At the same time, by setting up a usage mechanism, staff can quickly disassemble and use the breeding device.
[0029] Among them, reference Figure 2 and Figure 4 In a preferred embodiment, the mechanism includes a fixed frame 4 at both ends of the top of the frame 1. Each end of the fixed frame 4 has a slot 14. A roller 13 is rotatably connected inside the slot 14. A protective net 5 is fixedly connected to the inner side of the mounting rod 2. A rotating cylinder 6 is rotatably connected to the top of the mounting rod 2. A fixed rod 18 is rotatably connected inside the rotating cylinder 6. A connecting component for auxiliary installation is fixedly connected to the top of the fixed rod 18. A plug rod 12 is threadedly connected to the bottom of the fixed rod 18.
[0030] In this solution, by setting up a user mechanism, the user can simultaneously pull the two sets of mounting rods 2 that are slidably connected to the top of the frame 1. This allows the two sets of mounting rods 2 to stretch the protective net 5 during the sliding process, so that the protective net 5 can be rolled up and down outside the roller 13 and form a barrier on both sides of the frame 1. At the same time, by rotating the rotating drum 6 that is slidably connected to the top of the mounting rod 2 clockwise, the rotating drum 6 can drive the fixed rod 18 to rotate inside the mounting rod 2. This causes the fixed rod 18 to rotate and insert the threaded rod 12 at the bottom of the fixed rod into the soil of the aquaculture water area.
[0031] Furthermore, refer to Figure 2 and Figure 4 In a preferred embodiment, the connecting assembly includes a fixed cylinder 7 disposed at the top of the fixed rod 18. The fixed cylinder 7 has a toothed groove on its outer side and a toothed pattern on its inner side. The rotating cylinder 6 and the fixed cylinder 7 are meshed together.
[0032] The outer surface of the fixing rod 18 is provided with threads, and the inside of the insertion rod 12 is provided with threaded grooves. The fixing rod 18 and the insertion rod 12 are set on the same central axis. By setting a connecting component, the rotating drum 6 can rotate while driving the fixing drum 7 to rotate.
[0033] Among them, reference Figure 3 and Figure 5 In a preferred embodiment, the outer side of the roller 13 is provided with a winding groove, and one end of the protective net 5 is wound into the winding groove. The fixing component includes a through cylinder 8 set at the top of the insert plate 3. The two ends of the pull rope 9 are sleeved inside the through cylinder 8 through the clamp 15. By setting the fixing component, the pull rope 9 can be pulled out along the trajectory of the through cylinder 8.
[0034] Working principle: When staff raise crayfish;
[0035] First, when the staff is catching crayfish, by pressing down the button 11, the bottom fixed connection of the clamp 15 will slide down and the clamp 15 will squeeze the spring plate 16, so that the clamp 15 and the through groove opened on the outside of the limiting cylinder 10 are aligned, thereby pulling the pull rope 9 and making the pull rope 9 slide inside the through cylinder 8. During the pulling of the pull rope 9, the net bag 17 will be lifted, and the crayfish raised in the frame 1 can be caught.
[0036] Next, by simultaneously pulling the two sets of mounting rods 2 that are slidably connected to the top of the frame 1, the user can stretch the protective net 5 during the sliding process of the two sets of mounting rods 2, so that the protective net 5 can be rolled up and down outside the roller 13 and form a barrier on both sides of the frame 1. At the same time, by rotating the rotating cylinder 6 that is slidably connected to the top of the mounting rod 2 clockwise, the rotating cylinder 6 can drive the fixed cylinder 7 that is engaged with the inner side to rotate, so that the fixed rod 18 that is fixedly connected to the fixed cylinder 7 at the top rotates inside the mounting rod 2. During the rotation of the fixed rod 18, the insertion rod 12 that is threadedly connected to the bottom end rotates and is inserted into the soil of the aquaculture water area.
[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
