Description
Technical Field
The utility model relates to a crayfish breeding box with a net belongs to crayfish cultivation technical field.
Background
Crayfish (acambrus clarkii), also known as Procambarus clarkii, crayfish red crayfish and freshwater crayfish. The meat is popular with people because of delicious taste. Due to the omnivorous property, the fast growth speed and the strong adaptability, the method forms an absolute competitive advantage in the local ecological environment. The food intake range of the feed comprises aquatic weeds, algae, aquatic insects, animal carcasses and the like, and the feed can kill the aquatic weeds, the algae, the aquatic insects, the animal carcasses and the like in case of shortage of food. In the last two years, the crayfish market is fierce and the supply is not adequate, but the crayfish is mainly cultured in south areas such as Jiangsu and Hubei, and the yield is very low in the northeast. Because the temperature is low in northeast winter, the crayfishes and the shrimp seeds can not live through the winter naturally, which greatly limits the crayfishes from being cultured in the northeast area. In northeast areas, the crayfish is mated in 5-10 months, the hatched crayfish fries mainly span the whole cold winter in 10-2 months during breeding, and in view of the above, a greenhouse breeding method is adopted. Because the space of the greenhouse is limited, the culture density of the shrimp seeds in the pond in the greenhouse is greatly limited, and the large crayfishes are easy to kill the shrimp seeds, so that the yield is reduced. Therefore, after the shrimp larvae are hatched, the larvae need to be separated from the pond, and the larvae are usually caught by a catching method, but all the larvae cannot be caught, and the catching process is complicated and takes a long time.
SUMMERY OF THE UTILITY MODEL
Therefore, an object of the utility model is to provide a crayfish breeding box with a net, arrange the seed shrimp in the box with a net in, put into the pond with the box with a net, treat that the seed shrimp hatches out after the shrimp seedling can directly take box with a net and seed shrimp together from the pond.
In order to achieve the purpose, the crayfish breeding net cage comprises a frame and a net basket which is detachably arranged on the frame; the isolation net of the net basket is used for blocking the seed shrimps in the net basket; the frame comprises at least two transversely arranged inserting rods, and one ends of the inserting rods are free ends; the net basket is provided with a plurality of hanging rings, and the net basket is hung on the inserted bar through the hanging rings.
The inserted bars are arranged in parallel.
The net basket is in a cuboid shape after being unfolded and comprises 6 square isolation nets; non-woven fabric strips are arranged on at least two adjacent parallel edges of the rectangular net basket; the hanging ring is arranged on the non-woven fabric strip.
The number of the inserted rods is four; correspondingly, the number of the non-woven fabric strips provided with the hanging rings is four.
And a window is arranged on the isolation net at the top end of the net basket.
The position of the inserted bar close to the two ends is provided with a limiting part protruding upwards, and the limiting part can penetrate through the hanging ring.
The space enclosed by the frame is cuboid, and one end of at least two of the inserted bars is respectively fixed on the supporting vertical bars positioned on two adjacent vertical edges of the frame.
The frame further includes a base plate.
The crayfish breeding cage further includes a plurality of floats connected to the frame and capable of floating a portion of the basket out of the water.
The buoy is arranged on the outer side of the frame or in the basket, and is connected to the frame through a connecting rope.
By adopting the technical scheme, the crayfish breeding net cage can limit the breeding shrimps in the internal area of the net basket through the net basket which is arranged separately from the frame, and after the breeding shrimps hatch out the shrimp seedlings, the shrimp seedlings have smaller volume and can pass through the mesh holes of the isolation net on the net basket, so that the breeding shrimps can be directly taken away from the pond through the net basket; can hang on the inserted bar comparatively conveniently through the link on the basket, and directly shift down the link from the inserted bar when demolising the basket and can accomplish very conveniently.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the crayfish breeding net cage of the present invention comprises a frame 1 and a net basket 2 detachably mounted on the frame 1; the isolation net of the net basket 2 is used for blocking the seed shrimps in the net basket 2; the space enclosed by the frame 1 is cuboid, and comprises a bottom plate 11, four vertical supporting rods 12 arranged on the vertical sides, and four supporting top rods 13.
The frame 1 comprises four insertion rods 14 which are transversely arranged in parallel, and one end of each insertion rod 14 is a free end 14 a; the net basket 2 is provided with a plurality of hanging rings 21, and the net basket 2 is hung on the inserted bar 14 through the hanging rings 21. The ends of the four insertion rods 14 far away from the free ends 14a are respectively fixed on two adjacent vertical support rods 12.
The net basket 2 is in a cuboid shape after being unfolded and comprises 6 square isolation nets 20; non-woven fabric strips 22 are arranged between adjacent separation nets 20 on the rectangular net basket 2; the hanging ring 21 is arranged on the non-woven fabric strip 22. A window 23 is arranged on the isolation net at the top end of the net basket 2.
The inserting rod 14 is provided with a limiting part 141 protruding upwards at a position close to the two ends, and the limiting part 141 can penetrate through the hanging ring 21.
As shown in fig. 4, the crayfish breeding cage further includes a plurality of floats 3 attached to the frame 1 and capable of floating a part of the basket 2 out of the water.
The buoy 3 is arranged outside the frame 1 or inside the basket 2, and the buoy 3 is connected to the frame 1 through a connecting rope 4.
The size of the net cage can be determined according to the size of the pond, for example, a net cage frame 1 with the length of 6 meters, the width of 3 meters and the height of 2 meters is manufactured, the net basket 2 is exposed out of the water surface by 40cm, the escape of crayfishes is prevented, and six pairs of floats 3 are arranged on the net cage and can be used for controlling the up-and-down floating of the net cage.
