Description

Technical Field

[0001] This utility model relates to the field of agricultural aquaculture technology, specifically to a rice paddy fish-blocking device that is easy to use and adjust. Background Technology

[0002] Rice-fish farming should prioritize rice cultivation while also considering fish farming. This guiding principle is based on the theory of rice-fish symbiosis, utilizing artificially established rice-fish symbiotic relationships to transform the original rice paddy ecology in a more favorable direction, thereby achieving the goal of increased rice production and a bountiful fish harvest.

[0003] Commonly used rice paddy fish barriers are mostly made of bamboo strips, willow branches, wooden sticks, or wire mesh and screens. They are easily damaged and cannot be reused. They are also inconvenient to install. Moreover, these fish barriers are not easy to adjust the angle and splice together, which causes many inconveniences during use and reduces the practicality of the main body of the fish barrier. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a user-friendly and adjustable fish-blocking device for rice paddies. This addresses the issues mentioned in the background section, where common rice paddy fish barriers are often made of bamboo strips, willow branches, wooden sticks, or wire mesh and screens, making them easily damaged and unusable. Furthermore, these barriers are inconvenient to install and difficult to adjust and assemble, resulting in numerous inconveniences during use and reducing the overall practicality of the fish-blocking device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice paddy fish-blocking device that is easy to use and adjust, comprising a main body of the fish-blocking device, two mounting frames arranged opposite each other inside the main body of the fish-blocking device, a first insert rod fixedly installed at the bottom of each of the two mounting frames, a connecting block fixedly installed on the mounting frame on the right side inside the main body of the fish-blocking device, a first positioning hole opened at the top of the connecting block, a positioning post fixedly installed at the bottom of the connecting block, a connecting frame installed at the bottom of the mounting frame on the left side of the main body of the fish-blocking device, a second positioning hole opened on the connecting frame, and a connecting plate fixedly installed on the mounting frame on the left side of the main body of the fish-blocking device closer to the top.

[0006] Using the above technical solution, the first insert rod installed at the bottom of the two mounting frames can effectively insert the main body of the fish barrier into the paddy field, thereby stabilizing the main body of the fish barrier in the paddy field. When it is necessary to splice the main bodies of the fish barrier, the workers can connect the connecting block installed on the right side of the mounting frame to the connecting frame and connecting plate on the left side of the mounting frame of the other main body of the fish barrier, thereby connecting the two main bodies of the fish barrier.

[0007] Preferably, a threaded rod is inserted into the connecting plate, a knob is fixedly installed at the top of the threaded rod, a limit plate is fixedly installed at the bottom of the threaded rod, and a fixing rod is fixedly installed at the bottom of the limit plate.

[0008] Using the above technical solution, by rotating the knob, the knob drives the threaded rod to descend. When the threaded rod descends, it drives the fixing rod installed at the bottom of the limiting plate to descend as well, so that the limiting rod is inserted into the first positioning hole opened on the connecting block, thereby installing the two fish blocking device bodies together.

[0009] Preferably, the fish-blocking device has adjusting plates arranged opposite to each other at both ends of its main body, and a fixing plate is rotatably installed inside each adjusting plate, with a second insert rod fixedly installed at the bottom of each fixing plate.

[0010] Using the above technical solution, the second rod installed at the bottom of the fixed plate will also be inserted into the paddy field, thereby making the main body of the fish blocking device more stable in the paddy field. Since the fixed plate is rotatably installed in the adjusting plate, the fixed plate can drive the second rod to rotate, thereby reducing the volume of the main body of the fish blocking device.

[0011] Preferably, each of the inner end faces of the mounting bracket is fixedly mounted with a mounting plate, and each mounting plate is fixedly mounted with a plurality of fixed hooks arranged in a linear array.

[0012] Using the above technical solution, the fixing hooks on the mounting plate are connected to the through holes opened on both sides of the barrier net, thereby fixing the barrier net between the two mounting frames to block fish in the rice field.

[0013] Preferably, a barrier net is fixed between the mounting brackets, and multiple through holes arranged in a linear array are provided on both sides of the barrier net, and the barrier net is made of polyvinyl chloride.

[0014] By adopting the above technical solution, the material used for the barrier net is polyvinyl chloride, which makes the barrier net lightweight and has a corrosion-resistant and wear-resistant layer, thus significantly improving the service life of the barrier net.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This easy-to-use and adjustable rice paddy fish-blocking device connects to the connecting frame and connecting plate on the left side of the main body of another fish-blocking device via a connecting block installed on the right side of the mounting frame. Then, the positioning post at the bottom of the connecting block is inserted into the second positioning hole. The operator then rotates a knob, which causes the threaded rod to descend. When the threaded rod descends, it causes the fixing rod installed at the bottom of the limiting plate to descend as well, thus inserting the limiting rod into the first positioning hole on the connecting block. This allows the two main bodies of the fish-blocking device to be installed together, thereby extending the overall length of the main body of the fish-blocking device.

[0017] 2. This easy-to-use and adjustable rice paddy fish-blocking device allows the main body of the fish-blocking device to be inserted into the rice paddy through the first insertion rod installed at the bottom of the two mounting frames. At the same time, the second insertion rod installed at the bottom of the fixing plate will also be inserted into the rice paddy, thereby stabilizing the main body of the fish-blocking device in the rice paddy. Since the fixing plate is rotatably installed in the adjusting plate, the fixing plate can drive the second insertion rod to rotate, thereby reducing the size of the main body of the fish-blocking device.

A connecting plate 9 is fixedly mounted on the mounting frame 2 on the left side of the main body 1, near the top, and a threaded rod 1 is inserted into the connecting plate 9. 0. A knob 11 is fixedly installed at the top of the threaded rod 10. A limiting plate 12 is fixedly installed at the bottom of the threaded rod 10. A fixing rod 13 is fixedly installed at the bottom of the limiting plate 12. Mounting plates 17 are fixedly installed on the inner end faces of the mounting brackets 2. Multiple fixing hooks 18 arranged in a linear array are fixedly installed on the mounting plates 17. A barrier net 19 is fixed between the mounting brackets 2. Multiple through holes 20 arranged in a linear array are opened on both sides of the barrier net 19. The barrier net 19 is made of polyvinyl chloride.

[0026] Working principle: When it is necessary to splice the main bodies 1 of the fish-blocking device, the operator can connect the connecting block 4 installed on the right side of the mounting bracket 2 to the connecting bracket 7 and connecting plate 9 on the left side of the mounting bracket 2 of the other fish-blocking device main body 1. Then, the positioning post 6 at the bottom of the connecting block 4 is inserted into the second positioning hole 8. Then, the operator rotates the knob 11, which causes the threaded rod 10 to descend. When the threaded rod 10 descends, it will cause the fixing rod 13 installed at the bottom of the limiting plate 12 to descend, so that the limiting rod is inserted into the first positioning hole 5 opened on the connecting block 4, thereby connecting the two fish-blocking devices. The main body 1 is installed between the two main bodies 2 to extend the overall length of the fish barrier device 1 and allow for better rotation between the two main bodies 1, thereby adjusting the angle between them. The fixing hooks 18 on the mounting plate 17 can be connected to the through holes 20 on both sides of the barrier net, thus fixing the barrier net 19 between the two mounting frames 2 to block fish in the paddy field. The barrier net 19 is made of polyvinyl chloride, which makes it lightweight and has a corrosion-resistant and wear-resistant layer, thus improving its service life.

[0027] Example 2:

[0028] Please refer to the following: Figure 1-4 A rice paddy fish-blocking device that is easy to use and adjust includes two mounting brackets 2 arranged opposite each other inside the main body 1 of the fish-blocking device. A first insert rod 3 is fixedly installed at the bottom of each of the two mounting brackets 2. Adjustment plates 14 are arranged opposite each other at the front and rear ends of the main body 1 of the fish-blocking device. A fixed plate 15 is rotatably installed inside each adjustment plate 14. A second insert rod 16 is fixedly installed at the bottom of each fixed plate 15.

[0029] Working principle: The first rod 3 installed at the bottom of the two mounting brackets 2 can be used to insert the main body 1 of the fish blocking device into the paddy field. At the same time, the second rod 16 installed at the bottom of the fixing plate 15 will also be inserted into the paddy field, so that the main body 1 of the fish blocking device can be stabilized in the paddy field. Since the fixing plate 15 is rotatably installed in the adjusting plate 14, the fixing plate 15 can drive the second rod 16 to rotate, thereby reducing the volume of the main body 1 of the fish blocking device.
