Description

Technical Field

[0001] This utility model relates to the technical field of rice-shrimp farming equipment, and in particular to a floating shading device for rice-shrimp farming. Background Technology

[0002] my country has a large number of paddy fields distributed in its low and medium mountainous and hilly areas. These paddy fields generally have abundant water sources, good water quality, and convenient irrigation and drainage. At the same time, these water bodies are rich in organic matter, and the size of individual paddy fields is suitable. With existing technology, farmers have adapted to local conditions, and paddy field crayfish farming has become a very important crayfish farming method.

[0003] However, the water level in existing paddy fields is prone to changes with the weather. The water level can differ by ten or twenty centimeters before and after rain. The height of the shading device is fixed. When the water level is high, the shading cloth is stuck to the water surface. The cloth is not breathable, and the water is very stuffy, causing the shrimp to always float to the surface due to lack of oxygen. When the water level is low, the device is too high and cannot block the water below. The shrimp are exposed to the sun and hide in the mud, refusing to eat. Adjusting the height requires manually dismantling the support and re-fixing it, which is quite troublesome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a floating shading device for rice-shrimp farming. It solves the technical problems of existing rice paddy water levels easily varying by tens of centimeters with weather changes, while the shading device has a fixed height. When the water level is high, the shading cloth touches the water surface, causing the shrimp to float to the surface and lack oxygen. When the water level is low, the device is too high to block the water, causing the shrimp to hide in the mud and not eat. In addition, the device needs to be manually disassembled and re-fixed to adjust the height.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A floating shading device for rice-shrimp farming includes two sets of parallel poles. Each set of poles has a dovetail groove and a strip groove. A central strip is provided between each set of poles. Each of the two central strips has a limiting groove. Sliding rods are symmetrically slidably installed inside each of the two central strips. Dovetail blocks are fixedly installed on the side walls of each of the two sets of sliding rods. The dovetail blocks are slidably installed on the two sets of dovetail grooves. An adjustment mechanism is fixedly installed on the side walls of each of the two sets of sliding rods. The basic frame can be flexibly extended and retracted to adapt to different rice fields, allowing for quick installation without damaging the ecology.

[0007] The adjustment mechanism includes side blocks, with two sets of side blocks respectively fixedly connected to two sets of sliding rods. A first screw is rotatably installed inside each set of side blocks. The adjustment mechanism provides a stable drive for fixing the sunshade cloth, ensuring controllable clamping.

[0008] Preferably, both sets of sliding rods have cross grooves inside, both sets of cross grooves have cross blocks slidably installed inside, both sets of cross blocks have clamps fixedly installed on their side walls, both sets of clamps have circular grooves, both sets of clamps have second screws threaded inside, and both sets of second screws have third screws threaded inside. This material fixing structure allows for flexible switching between sunshade cloth and netting, and ensures a firm fixation without damaging the material.

[0009] Preferably, a connecting rod is fixedly installed on the upper end of each of the two dovetail blocks, a limiting screw is fixedly installed on each of the two connecting rods, a lifting block is slidably installed on each of the two sets of limiting screws, a float is fixedly installed on the side wall of each of the two sets of lifting blocks, and a threaded ring is threadedly installed on each of the two sets of limiting screws. The height adjustment structure can automatically adjust the height according to the water level, and manual fine adjustment is convenient and does not require disassembly.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This equipment features a flexible, extendable frame and an adaptable design that allows for easy switching between shading cloth and netting. Combined with automatic water level-responsive pontoons and precise manual adjustment of the threaded rings, it ensures the shading material maintains the optimal distance from the water surface. This precisely meets the needs of rice-shrimp farming for shading, ventilation, and turbidity prevention under varying weather conditions, while eliminating the need for frequent manual adjustments to the frame and height. This fundamentally safeguards the ecological balance of rice-shrimp symbiosis, expands applicable scenarios, reduces maintenance costs, and ultimately contributes to increased survival rates and rice yields.

Detailed Implementation

[0020] This application provides a floating shading device for rice-shrimp farming, which effectively solves the problems of existing rice paddy water levels that vary by tens of centimeters depending on the weather, while the shading device has a fixed height. When the water level is high, the shading cloth touches the water surface, causing the shrimp to float to the surface and suffer from oxygen deficiency. When the water level is low, the device is too high and cannot block the water, causing the shrimp to hide in the mud and not eat. In addition, the support frame needs to be manually disassembled and re-fixed to adjust the height. This device, with its retractable frame, cloth / net switching, automatic float linkage with the water level, and manual adjustment of the threaded ring, ensures that the shading material is always at the optimal distance from the water surface, meeting the needs of rice and shrimp, eliminating the need for frequent adjustments, ensuring a symbiotic balance, reducing costs, and helping to increase both shrimp survival rate and rice yield.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing paddy field water levels easily varying by tens of centimeters with weather changes, while the shading device height is fixed. When the water level is high, the shading cloth sticks to the water surface, causing the shrimp to float to the surface and lack oxygen. When the water level is low, the device is too high and cannot block the water, causing the shrimp to hide in the mud and not eat. In addition, the support needs to be manually disassembled and re-fixed to adjust the height. The overall idea is as follows: A floating shading device for paddy field shrimp farming includes two sets of parallel rods 1. Each set of rods 1 has a dovetail groove 2 and a strip groove 3. A center strip 4 is set between each set of rods 1. Each of the two center strips 4 has a limit groove 5. Each of the two center strips 4 has a sliding rod 6 symmetrically slidably installed inside. Dovetail blocks 8 are fixedly installed on the side walls of each of the two sets of sliding rods 6. The two sets of dovetail blocks 8 are slidably installed on the two sets of dovetail grooves 2 respectively. An adjustment mechanism is fixedly installed on the side walls of each of the two sets of sliding rods 6.

[0023] The adjustment mechanism includes side blocks 9, two sets of side blocks 9 are fixedly connected to two sets of slide rods 6 respectively, and a first screw 10 is rotatably installed inside each set of side blocks 9.

[0024] Both sets of sliding rods 6 have cross grooves 11 inside, and cross blocks 12 are slidably installed inside both sets of cross grooves 11. Clamping plates 13 are fixedly installed on the side walls of both sets of cross blocks 12. Circular grooves 14 are opened on both sets of clamping plates 13. Second screws 15 are threaded into both sets of clamping plates 13, and third screws 16 are threaded into both sets of second screws 15. In use, first insert the four rods 1 into the paddy field, then pull the sliding rods 6 outwards to adjust to the appropriate length. Then insert the dovetail block 8 into the dovetail groove 2. At this point, depending on the shading needs, you can choose to install either a shade cloth (used when the weather is hot and most sunlight needs to be blocked, or when rainwater erosion causes water turbidity) or a shade net (used to avoid strong midday sunlight and ensure the photosynthesis of rice). When installing the sunshade cloth, each corner of the sunshade cloth can be placed on each clamping plate 13. Then, the first screw 10 can be rotated on the side block 9. The rotation of the first screw 10 will drive the clamping plate 13 to move upward. The clamping plate 13 will drive the cross block 12 to move upward inside the cross groove 11. At this time, the clamping plate 13 and the side block 9 can complete the clamping and fixing of the corners of the sunshade cloth. The installation is completed by clamping and fixing the four corners of the sunshade cloth. When installing the sunshade net, the second screw 15 can be rotated on the clamping plate 13. The rotation of the second screw 15 will allow it to pass through the mesh of the sunshade net. Then, the third screw 16 can be rotated on the second screw 15 to complete the alignment and fixing. This device can be used for the arbitrary installation of sunshade cloth and sunshade net, and has a wider range of applications.

[0025] Two dovetail blocks 8 are each fixedly mounted with a connecting rod 17. Each connecting rod 17 is fixedly mounted with a limiting screw 18. Each limiting screw 18 has a sliding lifting block 19. Each lifting block 19 has a float 20 fixedly mounted on its side wall. Each limiting screw 18 has a threaded ring 21 threaded onto it. After installation, the float 20 will float on the water surface. The threaded ring 21 can then be rotated on the lifting block 19. Because the two are threadedly connected, the rotation of the threaded ring 21 will cause the lifting block 19 to move on the limiting screw 18. This will allow the lifting block 19 to adjust the height of the float 20. By adjusting the height of the float 20, the installation height of the sunshade cloth or sunshade net can be adjusted. The installation height can be automatically adjusted according to the water level, allowing the sunshade cloth / The net is always kept at the optimal distance from the water surface, which avoids both oxygen deficiency due to being too close to the water and insufficient shading due to being too high. It also eliminates the need for frequent manual repositioning, ensuring a stable low-light environment for shrimp and photosynthetic needs for rice. This is the core support for maintaining the balance of rice-shrimp symbiosis and reducing maintenance costs.

[0026] To address the problems existing in the prior art, this utility model provides a floating shading device for rice-shrimp farming. This device, with its retractable frame, cloth / net switching, automatic float linkage with water level, and manual adjustment of the threaded ring, ensures that the shading material is always at the optimal distance from the water surface, meeting the needs of rice and shrimp, eliminating the need for frequent adjustments, ensuring symbiotic balance, reducing costs, and helping to increase both shrimp survival rate and rice yield.

[0027] Working principle:

[0028] The first step is to insert the four rods 1 into the paddy field. Then, pull the sliding rod 6 outwards to adjust it to the appropriate length. Insert the dovetail block 8 into the dovetail groove 2. At this point, depending on the shading situation, you can choose to install either a shade cloth (used when it is hot and most of the sunlight needs to be blocked, or when it is used to prevent rainwater from washing away the water and causing turbidity) or a shade net (used to avoid strong midday sunlight and ensure the photosynthesis of rice). When installing the shade cloth, place each corner of the shade cloth on each clamp 13, and then rotate the first screw 10 on the side block 9. The rotation of the first screw 10 will... The clamping plate 13 will move upward, and the clamping plate 13 will move the cross block 12 upward inside the cross groove 11. At this time, the clamping plate 13 and the side block 9 can clamp and fix the corners of the sunshade cloth. The installation is completed by clamping and fixing the four corners of the sunshade cloth. When installing the sunshade net, the second screw 15 can be rotated on the clamping plate 13. The rotation of the second screw 15 will pass through the mesh of the sunshade net. Then, the third screw 16 is rotated on the second screw 15 to complete the alignment and fixation. This makes the device suitable for the arbitrary installation of sunshade cloth and sunshade net, and has a wider range of applications.

[0029] The second step involves the float 20 floating on the water surface after installation. At this time, the threaded ring 21 can be rotated on the lifting block 19. Since the two are threadedly connected, the rotation of the threaded ring 21 will cause the lifting block 19 to move on the limiting screw 18. At this time, the lifting block 19 will drive the float 20 to adjust its height. By adjusting the height of the float 20, the installation height of the shade cloth or shade net can be adjusted. The installation height can be automatically adjusted according to the water level, so that the shade cloth / net can always maintain the optimal distance from the water surface. This avoids oxygen deficiency due to being too close to the water or insufficient shading due to being too high, and also eliminates the need for frequent manual adjustments. It stably ensures the low light environment required by shrimp and the photosynthetic needs of rice, which is the core support for maintaining the balance of rice and shrimp symbiosis and reducing maintenance costs.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
