2, establish valve, can controlled water flow speed.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 has illustrated the perspective exploded view of collection seedling net cage device.
Embodiment
Please refer to Fig. 1, a kind of collection seedling net cage device, it comprises a net cage support 10, a net cage 20, one first tube connector 30 and one second tube connector 40.
Said net cage support 10 is prismatic framework, and what draw among the figure is the quadrangular framework.Said net cage 20 structures and net cage support 10 are adaptive.The drift angle place of said net cage support 10 and the drift angle place of net cage 20 are corresponding one by one and be connected with tether 23, through tether 23 net cage 20 are connected net cage support 10.
