Embodiment 1
[0027] Refer to the attached Figures 1~5 : a quick replacement device for fish and shrimp cages, comprising a fish and shrimp transfer channel formed by a single-head conveying pipe 8 and a multi-head conveying pipe 17, the single-head conveying pipe 8 includes a vertical pipe body, and the multi-head conveying pipe 17 includes a plurality of vertical pipes The upper part of the plurality of vertical pipe bodies is connected to the upper part of the single-head conveying pipe 8 through the horizontally arranged connecting pipes; the upper part of the multi-head conveying pipe 17 is provided with a support 14, and the support 14 is connected to the upper part of the conveying pipe 8 through a steering device. The hoisting frame 12; the pipe bodies of the single-head conveying pipe 8 and the multi-head conveying pipe 17 are both hydraulic conveying pipes. The spiral water supply ring 4 is provided with a water pipe outside, and the spiral water supply ring 4 is provided with an...
Embodiment 2
[0038] The diameters of the plurality of spiral water supply rings 4 are gradually increased. A plurality of spiral water supply rings 4 are sheathed with a stepped pipe body. The stepped pipe body is a double-layered pipe, and a water supply cavity 3 is formed between the double-layered pipes. The water supply cavity 3 communicates with the spiral water supply ring 4 . A filter screen is provided at the water inlet end or the water outlet port of the spiral water supply ring 4 . Other settings and working procedures are the same as in Example 1.
Embodiment 3
[0040] Another type of steering device includes a rotating shaft 13. The rotating shaft 13 is provided with two sets of vertical and parallel sets. The two sets of rotating shafts 13 are all lead screws. The lower part of the rotating shaft 13 is threadedly connected to a bracket 14. Two threaded through holes are symmetrically arranged on both sides of the horizontally arranged connecting pipe; the hoisting frame 12 on the upper part of the rotating shaft 13 is provided with a screw rotating motor. The steering device of this structure realizes the rotation of the lead screw by starting the lead screw rotating motor, and realizes the rotation of the bracket 14 through the thread rotation of the lead screw and the two threaded through holes provided on the connecting bracket 14, thereby realizing the single The 180-degree reversal of the head conveying pipe 8 and the multi-head conveying pipe 17 is the same as that of Embodiment 1 in other settings and working processes.
