Fig. 2 is the concrete applicable cases schematic diagram of isolation feeding device shown in Figure 1.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, the isolation feeding device of the cultured fishes among the embodiment mainly is comprised of staking out 1, hook 2, net cage 3 and weight 4.
Among the embodiment shown in Figure 1, described staking out 1 has four, be respectively the first staking out 1a, the second staking out 1b, the 3rd staking out 1c and the 4th staking out 1d, they surround a rectangular area, wherein the first staking out 1a, the 4th staking out 1d vertically are plugged in feeding platform both sides, and the second staking out 1b, the 3rd staking out 1c vertically are plugged in the pond; The upper end of described four staking outs 1 certain-length that surfaces, the upper end of every staking out 1 all are equipped with hook 2; Described net cage 3 is arranged in the rectangular area that is surrounded by four staking outs 1, net cage 3 upper end open are the rectangular shapes with four sides, one of them side is over against the feeding platform, first jiao of A at net cage 3 upper end open edges, second jiao of B, third angle C, the 4th jiao of D are hung on the hook 2 of the first staking out 1a, the second staking out 1b, the 3rd staking out 1c, the 4th staking out 1d, and net cage 3 bottoms are certain depth because the Action of Gravity Field of self sinks under the water.
In the utility model, described staking out 1 can be the materials such as armored concrete, wood, and staking out 1 is inserted in the pond vertically, staking out 1 wants firm, can not skew in traction, the length of staking out 1 is decided according to the pond depth of water, only needs to guarantee that the surface length of part of a staking out 1 is that 0.5 ~ 0.8m gets final product.For not affecting fish movement, the sink under the water height of part of described net cage 3 bottoms is at least 1m.In the utility model, a plurality of hooks spaced apart 2 can be set on one section that described staking out 1 is surfaced, can adjust according to actual needs like this height and position of net cage 3.
In the utility model, described net cage 3 is comprised of rack 3a and net sheet 3b, net sheet 3b be installed in rack 3a around and the bottom.In actual use, net sheet 3b breakage can occur inevitably, so the net sheet 3b in the utility model preferably is installed on the rack 3a in the mode of detachable replacing, is convenient to like this replacing of net sheet 3b.The size of mesh of described net sheet 3b can be determined according to the little fish size of large fish, can stop large fish as long as small fish can be freed in and out also.
As shown in Figure 1, the bottom of each side of described net cage 3 evenly be equipped with respectively can sedimentation in water weight 4, the material of weight 4 can be iron, stone, fragment of brick isodensity much larger than the material of water, the effect of weight 4 is to make net cage 3 bottom sinking certain depths and not floating with water.In the illustrated embodiment, be provided with three weights 4 on described net cage 3 each side, the weight of each weight 4 is 0.5 ~ 2 kg/.
Concrete applicable cases of the present utility model is as follows:
As shown in Figure 2, isolation feeding device of the present utility model is arranged on feeding platform the place ahead, little fish culture is in net cage 3, during feeding, the feed of feeding small fish is thrown in net cage 3, fed the feed of large fish and throw outside net cage 3, large fish advances not go because small fish can free in and out net cage 3, therefore large fish can't be had the little fish meal of throwing in net cage 3, guarantees that small fish can not eat without feed owing to the striving food of large fish, effectively overcomes large fish and small fish competition food problem.
Isolation feeding device of the present utility model also can be arranged to net cage 3 form that can rise from the water surface or sink under water, and that works sinks under water net cage 3 after feeding finishes, thereby makes the large fish small fish can be freely movable in whole water body.
