Technical Field
The invention relates to novel rice field shrimp and crab polyculture equipment.
Background
In the rice field cultivation, the rice field area is large, and rice seedlings in the rice field are flourishing, so that the claw parts of the shrimps and the crabs cannot be well realized, and the rice seedlings are greatly damaged during capturing.
Based on the above problems, it is desirable to provide a device for polyculture of shrimps and crabs in a rice field in a garden, which can conveniently gather shrimps and crabs and can conveniently capture the shrimps and crabs.
Disclosure of Invention
The invention aims to solve the technical problem of providing a shrimp and crab polyculture device for a rice field in a park, which can conveniently gather shrimps and crabs and can conveniently capture the shrimps and crabs.
The invention is realized by the following technical scheme:
a novel rice field shrimp and crab mixed culture device comprises two shielding structures which are arranged in a rice field in parallel, a capture gap is formed between the two shielding structures, each shielding structure comprises a base poured at the bottom of the rice field, two ends of the base extend to positions on two sides of the rice field, a plurality of blocking pipes are poured inside the base, the upper ends of the blocking pipes are flush with the upper surface of the base, a frame structure is matched above the base, an inserting rod matched with the blocking pipes is arranged at the bottom of the frame structure, the inserting rod and the frame structure are welded and fixed, an isolation net is fixedly arranged inside the frame structure, the aperture of meshes of the isolation net is smaller than 1.5mm, a plurality of conical through openings are formed in one side, close to the capture gap, of the isolation net, and the end, far away from the isolation net, is gradually reduced, a plurality of ring parts are sewed on the outer wall of the through opening, and a tightening rope is arranged among the ring parts in a penetrating way.
Preferably, the surface of the frame structure is provided with a pressing strip for pressing the isolation net, a connecting part is arranged on one side of the pressing strip away from the isolation net, and a screw is matched between the connecting part and the frame structure.
Preferably, the top position of the side, far away from the catching gap, of the frame structure is provided with a feed trough, the bottom of the feed trough is provided with a leak hole, aquatic animals in the rice field are used as food in the daily state of the shrimps and crabs, when the catching of the shrimps and crabs is realized, the feed can be put in through the feed trough, water is filled in the feed trough after the feeding is completed, the feed is flushed out from the leak hole under the action of the water, so that the feed enters the rice field, and the feed is put in the position close to the catching gap, so that the shrimps and crabs can enter the catching gap in a favorable manner when eating, and the catching amount in the day is increased.
Preferably, the aperture of the opening of the through opening is 10cm to 15cm when the tightening rope is in a relaxed state, and the opening of the through opening is closed when the tightening rope is in a completely tightened state.
The device has the advantages that the through opening is sealed in the shrimp and crab growing process, when the shrimps and crabs grow, only part of the through opening needs to be opened, and then the shrimps and crabs can be caught in the catching clearance conveniently.
The invention has the beneficial effects that: the device can realize the co-culture of the shrimps and the crabs in a single rice field, can induce the shrimps and the crabs into the catching clearance when the shrimps and the crabs are caught, is convenient to catch, avoids the damage to rice seedlings, has a simple structure, is low in cost, and is suitable for popularization and use.
