The present application relates to the field of vegetable planting technology based on fish and
plant symbiosis, in particular to a fish and
plant symbiotic planting device and its using method, the middle section of the water suction
pipe is smoothly extended through the folding
assembly, the upper end of the water inlet cavity is provided with a winding frame, one end of the waterproof cloth is rotatably wound on the winding frame, the winding frame and the folding
assembly are linked through the transmission
assembly, the beneficial effect is that: by setting the cleaning device with waterproof cloth and water suction tank synchronous sliding, the sliding direction is guided by the arc-shaped
chassis, the fish floats upward, the waterproof cloth is used for separation, the fish
manure and other organic matters are prevented from being raised to cause water
turbidity, the fish is protected from the influence of the
brush, the synchronous operation of the folding assembly and the winding frame is realized through the
transmission ratio of the relative
bevel gear, the waterproof cloth and the water suction
pipe are adapted to the transverse sliding of the arc-shaped
chassis, synchronous cleaning is realized, linkage adjustment of multiple driving elements is avoided, and the convenience of cleaning is greatly improved.
