Description

Technical Field

[0001] This utility model relates to the field of fish fishing technology, specifically to a fish fishing device suitable for rice-fish integrated farming. Background Technology

[0002] Rice-fish integrated farming, as a typical representative of ecological circular agriculture, achieves the economic benefits of "dual use of water and multiple harvests from one field" through the synergistic coexistence of rice cultivation and fish farming. This is achieved by digging ditches in the rice paddies to connect fishponds, creating habitats and activity channels for fish. However, because the ditches dug in the rice paddies are relatively small, the working space is narrow when fish need to be caught (such as through seine netting), making traditional mechanical fishing difficult to implement, while manual fishing requires a large amount of manpower. Therefore, we propose a fish-catching device suitable for rice-fish integrated farming to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a fish harvesting device suitable for rice-fish integrated farming to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fish catching device suitable for rice-fish integrated farming, comprising two base plates, with guide rails fixedly connected to the top ends of the two base plates respectively. The sliders of the guide rails are fixedly connected to the bottom ends of columns. Support tubes are fixedly connected to one side of the top end of each column. The support tubes are coaxially arranged opposite each other, and each support tube is inserted into one end of a crossbar. The other end of the crossbar is inserted into both sides of a connecting block. Installation slots are respectively opened at the bottom of the crossbar, and installation blocks are slidably engaged within the installation slots. One end of an adjustment component is fixedly connected to the bottom end of each installation block. An installation frame is fixedly installed at the other end of the adjustment component. A catching net is fixedly installed on the outer side of each installation frame, and barbels are fixedly installed on the inner sidewall of each installation frame.

[0005] Preferably, the base plate has through holes at each of its four corners.

[0006] Preferably, the two ends of the crossbar are respectively provided with concave connecting grooves, and the connecting grooves and connecting blocks are inserted into each other.

[0007] Preferably, the mounting slot has a T-shaped cross-section, and the mounting block has a T-shaped structure.

[0008] Preferably, the adjustment assembly includes a support cylinder, an adjustment nut, a threaded rod, a support disc, and a mounting screw. One end of the support cylinder is fixedly connected to a mounting block, and the other end of the support cylinder is rotatably connected to the adjustment nut. The threaded rod is sleeved inside the adjustment nut through a threaded structure. One side of the threaded rod is slidably sleeved inside the support cylinder, and the other end of the threaded rod is fixedly connected to one end of the support disc. The other end of the support disc is coaxially fixedly connected to the mounting screw.

[0009] Preferably, the outer wall of the threaded rod is recessed with a guide groove, and a limiting slider is slidably engaged in the guide groove. The limiting slider is fixedly connected to the inner wall of the support cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The modular design allows for flexible adjustment and assembly according to the size of the rice paddy. Whether it is a small experimental field or a large planting area, it can quickly adapt to the corresponding scale of the fishing device, greatly improving the versatility and practicality of the device. This modular design not only simplifies the installation process and reduces the time and difficulty of on-site construction, but also facilitates subsequent maintenance and component replacement, reducing the cost of long-term use.

[0012] 2. The matching of the mounting block and the mounting slot allows for precise adjustment of the position of the fishing net according to actual needs; this dynamic adjustment capability is particularly important for the rice-fish integrated farming model, as it allows operators to flexibly change the fishing area according to the activity habits and distribution density of fish, thereby improving fishing efficiency and reducing interference with non-target areas, thus protecting the ecological balance of the paddy field.

[0013] 3. The plug-in design of the crossbar and the connecting block, as well as the T-shaped snap-fit ​​of the mounting slot and the mounting block, ensure the stability and reliability of the entire device structure. It is not only easy to assemble and disassemble, but also maintains the integrity of the structure when subjected to large external forces, preventing parts from falling off or being damaged due to vibration or impact, and ensuring the safe operation of fishing.

[0014] 4. The design of the adjustment components, especially the threaded engagement between the adjusting nut and the threaded rod, enables precise adjustment of the height of the installation frame and the fishing net, allowing the device to adapt to paddy fields with different water depths. Whether in shallow or deep water areas, it can be easily adjusted to the optimal fishing position, improving the targeting and success rate of the fishing.

[0015] 5. The barbed opening design on the inner side wall of the installation frame effectively prevents fish from escaping after they enter the fishing net, increasing the catch per catch. At the same time, the special structure of the barbed opening will not cause serious harm to the fish, which is in line with the concept of eco-friendly fishing, helps to protect fishery resources, and promotes the sustainable development of rice-fish integrated farming.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a fish catching device suitable for rice-fish integrated farming, including two base plates 1. The top ends of the two base plates 1 are respectively fixedly connected to guide rails 2. The sliders of the guide rails 2 are respectively fixedly connected to the bottom ends of columns 3. The top one side of the column 3 is respectively fixedly connected to a support tube 4. The support tubes 4 are coaxially arranged opposite each other and are respectively inserted into one end of a crossbar 6. The other end of the crossbar 6 is respectively inserted into both sides of a connecting block 13. The bottom of the crossbar 6 is respectively provided with an installation slot 61. The installation slot 61 is respectively slidably engaged with an installation block 7. The bottom end of the installation block 7 is respectively fixedly connected to one end of an adjustment component 8. The other end of the adjustment component 8 is respectively fixedly installed with an installation frame 9. The outside of the installation frame 9 is respectively fixedly installed with a catching net 10. The inner side wall of the installation frame 9 is respectively fixedly installed with a barbel opening 11.

[0023] Example 2

[0024] Reference Figure 1-3This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the four corners of the base plate 1 are provided with circular holes 101. The assembled device is placed in the paddy field, and the base plate 1 contacts the paddy field ground. The circular holes 101 at the four corners of the base plate 1 can be used to insert fixing stakes to further fix the position of the device and prevent the device from moving during the fishing process.

[0025] Specifically, the two ends of the crossbar 6 are respectively provided with concave connecting grooves 62, and the connecting grooves 62 and the connecting block 13 are inserted into each other.

[0026] Specifically, the mounting slot 61 has a T-shaped cross-section, and the mounting block 7 has a T-shaped structure.

[0027] Specifically, the adjustment assembly 8 includes a support cylinder 81, an adjustment nut 82, a threaded rod 83, a support plate 84, and a mounting screw head 85. One end of the support cylinder 81 is fixedly connected to the mounting block 7, and the other end of the support cylinder 81 is rotatably connected to the adjustment nut 82. The threaded rod 83 is sleeved inside the adjustment nut 82 through a threaded structure. One side of the threaded rod 83 is slidably sleeved inside the support cylinder 81, and the other end of the threaded rod 83 is fixedly connected to one end of the support plate 84. The other end of the support plate 84 is coaxially fixedly connected to the mounting screw head 85.

[0028] Depending on the fishing depth, manually operate the adjustment component 8 and manually rotate the adjustment nut 82. The adjustment nut 82 engages with the threaded rod 83, causing the threaded rod 83 to slide within the support cylinder 81. This, in turn, moves the support plate 84 and the mounting screw head 85. The mounting screw head 85 is fixedly connected to the mounting frame 9. The mounting screw head 85 is inserted into the round hole on the mounting frame 9, and the mounting screw head 85, together with the nut, fixes the mounting frame 9, thereby adjusting the height of the mounting frame 9 and the fishing net 10. Once the appropriate height is reached, stop rotating the adjustment nut 82. Due to the self-locking nature of the threaded structure, the threaded rod 83 will remain stable in that position, ensuring that the fishing net 10 is at the set fishing depth.

[0029] Furthermore, the outer wall of the threaded rod 83 is recessed with a guide groove 831, and a limit slider 811 is slidably engaged in the guide groove 831. The limit slider 811 is fixedly connected to the inner wall of the support cylinder 81. The sliding engagement of the guide groove 831 and the limit slider 811 allows the threaded rod 83 to move linearly through the threaded structure when the adjusting nut 82 is manually operated.

[0030] The working principle and process are as follows: During assembly, one end of a crossbar 6 is inserted into a support tube 4, and then the crossbar 6 is fixed at one end by bolt 5 through the threaded hole on the crossbar 6. A rectangular connecting block 13 is inserted into the connecting groove 62 at the other end of the crossbar 6. Both the connecting block 13 and the connecting groove 62 have threaded holes, which are used with bolt 12 to fix the crossbar 6 and the connecting block 13. Then, according to the size of the paddy field, multiple crossbars 6 of appropriate length are assembled. The ends of the multiple crossbars 6 are fixedly connected by the connecting blocks 13. Finally, the crossbar 6 at the tail end is inserted into another... Inside the support tube 4, the crossbar 6 is fixed by bolts 5 through threaded holes, forming a U-shaped structure. Before assembling the crossbar 6, a corresponding number of mounting blocks 7 are inserted into the mounting slots 61 of the crossbar 6 according to actual needs. Depending on the fishing depth, the adjustment component 8 is manually operated, and the adjustment nut 82 is manually rotated. The adjustment nut 82 engages with the threaded rod 83, causing the threaded rod 83 to slide within the support tube 81, thereby moving the support plate 84 and the mounting screw head 85. The mounting screw head 85 is fixedly connected to the mounting frame 9, and the mounting screw head 85 is inserted into the round hole on the mounting frame 9. 5. Install the screw head 85 and nut to fix the mounting frame 9, thereby adjusting the height of the mounting frame 9 and the fishing net 10. After adjusting to the appropriate height, stop rotating the adjusting nut 82. Due to the self-locking nature of the threaded structure, the threaded rod 83 will remain stable in this position, ensuring that the fishing net 10 is at the set fishing depth. Then, place the assembled device in the paddy field, with the base plate 1 in contact with the paddy field ground. The round holes 101 at the four corners of the base plate 1 can be used to insert fixing stakes to further fix the position of the device and prevent it from moving during the fishing process. During fishing, fish will enter the fishing net 10 either with the water flow or guided by the fishing net 10. The net 10 and the barbed opening 11 on the inner side wall of the mounting frame 9 will prevent fish from escaping. After a certain period of fishing, the operator can lift the mounting frame 9 and the net 10 by rotating the adjusting nut 82 in the opposite direction to remove the captured fish. If it is necessary to fish in different areas, the column 3 can be moved through the guide rail 2, thereby moving the entire device to a new fishing position. If the size of the paddy field changes, the size of the device needs to be adjusted. Bolt 1 5 and Bolt 2 12 can be removed, the crossbar 6 and the connecting block 13 can be disassembled, and the crossbar 6 of appropriate length can be reassembled to adapt to the new size of the paddy field.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
