Description

Technical Field

[0001] This invention relates to the field of rice-shrimp farming technology, and in particular to a separating device for rice-shrimp symbiotic farming. Background Technology

[0002] Rice-field aquaculture is an ecological aquaculture model that promotes a virtuous cycle within the rice-field ecosystem based on the principles of ecological economics. Rice-field aquaculture can harvest a considerable amount of aquatic products while saving labor, effort, and feed, and can also increase rice yield by more than 10% without increasing input.

[0003] The following problems were found in the use of existing rice-shrimp farming separation nets that have not been well resolved: Shrimp will burrow, and the soil in the paddy field is relatively soft and easy to burrow into. This makes it easy for shrimp to burrow out from the bottom of the separation net, thus rendering the separation net ineffective. At the same time, existing rice-shrimp farming separation nets usually use grid nets to separate shrimp and crabs, but grid nets are easy for shrimp and crabs to climb over, resulting in poor separation effect. Summary of the Invention

[0004] The purpose of this invention is to provide a separation device for rice-shrimp co-culture.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A separating device for rice-shrimp co-culture includes multiple sets of inserted rods arranged in parallel. Each inserted rod has a U-shaped notch at its bottom, within which a stainless steel baffle is fixed by bolts I. Each inserted rod has a horizontal bar perpendicular to the baffle at its top. The tops of any two adjacent sets of inserted rods are connected by a connecting mechanism. Both sides of the parallel inserted rods are also inclined with a barrier net. The bottom of the barrier net has a strip plate hinged to the bottom of the corresponding inserted rod via a hinge. The top of the barrier net has a strip-shaped elastic element, and the top of the elastic element has a hanging ring corresponding to the horizontal bar. Multiple sets of hooks are evenly arranged at the top of both ends of the horizontal bar, and the hanging ring is fastened to one set of hooks.

[0007] Preferably, the connecting mechanism includes connecting rods disposed on both sides of the top end of the plug rod, wherein the straight line formed by the multiple sets of connecting rods is perpendicularly intersecting the crossbar. One set of connecting rods on both sides of the plug rod has a rectangular notch I at the top end, and the other set of connecting rods has a rectangular notch II at the bottom end that can be fastened to the corresponding rectangular notch I. The rectangular notch I has a hexagonal through hole, and the bottom of the rectangular notch II has a hexagonal positioning rod that passes through the through hole on the corresponding rectangular notch I.

[0008] Preferably, a support rod is provided at the bottom of the end of the crossbar, and the top of the support rod and the end of the crossbar are provided with screw holes for mounting bolt II.

[0009] Preferably, wind chimes and colorful ribbons are suspended from the netting.

[0010] Preferably, inclined plates are provided on both sides of the bottom of the insertion rod, and the strip plate is located above the inclined plates.

[0011] Preferably, the top of the baffle is higher than the horizontal plane of the bottom of the barrier net.

[0012] The beneficial effects of this invention are as follows: By tilting the barrier net, when shrimp and crabs climb the net, they will quickly fall off the net due to gravity, thus preventing them from climbing over it. Furthermore, the two sets of tilted nets provide multi-layered protection, reducing the chance of escape. Additionally, the baffles inserted into the mud prevent shrimp and crabs from burrowing underground and escaping, and these baffles also enhance the stability of the inserted poles to some extent.

Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] A separating device for rice-shrimp co-culture includes multiple sets of insert rods 1 arranged in parallel. Each insert rod 1 has a U-shaped notch 2 at its bottom end. Stainless steel baffles 3 are fixed in the multiple sets of U-shaped notches 2 by bolts I4.

[0019] The top of the insertion rod 1 is provided with a horizontal bar 5 that is perpendicularly intersecting the baffle 3. The tops of any two adjacent sets of insertion rods 1 are connected by a connecting mechanism 6. The sides of the multiple sets of insertion rods 1 arranged in parallel are also inclined with a barrier net 7. The top of the baffle 3 is higher than the bottom horizontal plane of the barrier net 7. The bottom of the barrier net 7 is provided with a strip plate 9 that is hinged to the bottom of the corresponding insertion rod 1 by a hinge 8. The top of the barrier net 7 is provided with a strip elastic element 10. The top of the elastic element 10 is provided with a hanging ring 11 corresponding to the horizontal bar 5. Multiple sets of hooks 12 are evenly provided at the top of both ends of the horizontal bar 5. The hanging ring 11 is fastened to one set of hooks 12.

[0020] The connecting mechanism 6 includes connecting rods 61 arranged on both sides of the top end of the insertion rod 1. The straight line formed by the multiple sets of connecting rods 61 is perpendicular to the crossbar 5. One set of connecting rods 61 on both sides of the insertion rod 1 has a rectangular notch I62 at the top end, and the other set of connecting rods 61 has a rectangular notch II63 at the bottom end that can be fastened to the corresponding rectangular notch I62. The rectangular notch I62 has a hexagonal through hole 64, and the bottom of the rectangular notch II63 has a hexagonal positioning rod 65 that passes through the through hole 64 on the corresponding rectangular notch I62.

[0021] like Figure 1 , 2 As shown, a support rod 13 is provided at the bottom of the end of the crossbar 5, and the top of the support rod 13 and the end of the crossbar 5 are provided with screw holes 14 for installing bolts II15. In use, support rods 13 can be added to both ends of the crossbar 5 to support and fix the crossbar 5 and the insert rod 1, thereby improving the stability of the above components.

[0022] In this embodiment, wind chimes and colorful ribbons are suspended on the net 7. When a breeze blows the ribbons and the wind chimes, if there are shrimp or crabs climbing on the net 7, the flying ribbons can scare away birds and other animals. At the same time, the sound of the wind chimes can also have the same effect, reducing the chances of other animals preying on the shrimp or crabs climbing the net 7.

[0023] like Figure 2 , 3 As shown, inclined plates 16 are provided on both sides of the bottom of the insertion rod 1, and the strip plate 9 is located above the inclined plates 16. When the barrier net 7 is not in use, the hanging ring 11 separates from the hook 12, and the barrier net 7 is rolled up so that the rolled-up barrier net 7 is placed in the angle formed between the inclined plates 16 and the insertion rod 1 for temporary storage.

[0024] Usage: Multiple sets of insertion rods 1 are connected via connecting mechanism 6, as detailed below. Figure 1As shown, the positioning rod 65 on the rectangular notch II63 is inserted into the through hole 64 in the corresponding rectangular notch I62. At the same time, the baffle 3 is inserted into multiple sets of U-shaped notches 2 and bolts I4 are installed to lock and fix it. The position of the baffle 3 in the U-shaped notch 2 can be adjusted according to the required insertion depth of the baffle 3. Then, the insertion rod 1, the support rod 13 and the baffle 3 are inserted into the ground.

[0025] Next step Figure 1 As shown, pulling the elastic element 10 causes the barrier net 7 to rotate around the hinge 8, thus tilting the barrier net 7. Simultaneously, pulling the hanging ring 11 causes the elastic element 10 to extend, ultimately causing the hanging ring 11 to fasten onto one of the hooks 12. Figure 3 As shown, the net 7 should be tilted and tightened.

[0026] This invention uses an inclined setting for the barrier net 7, so that when shrimp and crabs climb the barrier net 7, they will quickly fall off the barrier net 7 due to gravity, thus preventing them from climbing over the barrier net 7. At the same time, the two sets of inclined barrier nets 7 can provide multi-layered obstruction for shrimp and crabs, reducing the chance of them escaping. Furthermore, the baffle 3 inserted into the mud prevents shrimp and crabs from burrowing underground to escape. The baffle 3 also strengthens the stability of the insert rod 1 to a certain extent. In use, a horizontal plate can be fixed to the top of the baffle 3 between any two adjacent sets of insert rods 1 with screws. When the barrier net 7 or strip plate 9 is inclined and taut, the end of the horizontal plate contacts the side wall of the barrier net 7 or strip plate 9, preventing a large gap between the baffle 3 and the strip plate 9 or barrier net 7 from allowing shrimp and crabs to escape through the gap.

[0027] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
