Fishpond bottom dredging device for marine fishery breeding

Abstract

The invention discloses a fishpond bottom dredging device for marine fishery breeding. The fishpond bottom dredging device for marine fishery breeding comprises a ship body, wherein the ship body comprises a sludge chamber, a drainage chamber, an air cylinder chamber and a power chamber, a baffle is arranged in the sludge chamber in a connected mode and divides the sludge chamber into a sludge discharging area and a drying area, a pump is arranged above the sludge discharging area in a connected mode, one end of the pump is connected with a sludge suction device, the other end of the pump is connected with a sludge discharging pipe, the other end of the sludge discharging pipe extends into the sludge discharging area, the sludge discharging area is connected with a filter screen on the side wall of one side of the lower part of the baffle, two sides of the filter screen are correspondingly connected with a sludge scraping plate and a driving device, the power chamber is internally connected with electricity storage equipment and a first motor, the power output end of the first motor is connected with a first hollow connecting rod, the other end of the first connecting rod is internally connected with a second motor in a sealed mode, and the power output end of the second motor penetrates through the first connecting rod to be connected with paddles. The fishpond bottom dredging device for marine fishery breeding has the advantages that water in sludge can be drained, and the sludge and the water are correspondingly discharged out of the ship body after being separated.

Description

technical field [0001] The invention relates to the technical field of marine fishery cultivation equipment, in particular to a fish pond bottom dredging device for marine fishery cultivation. Background technique [0002] my country is the largest aquaculture country in the world, and the output of aquaculture aquatic products accounts for 70% of the world's total. The density of fry cultured in marine fish ponds is generally high, resulting in a large amount of feces, residual bait and other particulate matter deposited at the bottom of the pond, resulting in The deterioration of the pond water body will reduce the survival rate and growth rate of fish fry. The traditional method of dredging the bottom of fish ponds in marine fisheries is that fishermen carry sand pumps into the fish ponds to pump the sludge from the fish ponds to the shore. The water level in the fish pond is relatively deep and the visibility is low. Fishermen are prone to slipping and falling in the fish ...

[0002] my country is the largest aquaculture country in the world, and the output of aquaculture aquatic products accounts for 70% of the world's total. The density of fry cultured in marine fish ponds is generally high, resulting in a large amount of feces, residual bait and other particulate matter deposited at the bottom of the pond, resulting in The deterioration of the pond water body will reduce the survival rate and growth rate of fish fry. The traditional method of dredging the bottom of fish ponds in marine fisheries is that fishermen carry sand pumps into the fish ponds to pump the sludge from the fish ponds to the shore. The water level in the fish pond is relatively deep and the visibility is low. Fishermen are prone to slipping and falling in the fish pond, causing danger. Moreover, when the existing fish pond bottom dredging device for marine fish farming cleans the fish pond, the sludge The water in the tank is pumped to the bank along with the sludge, resulting in a waste of water resources. At the same time, the existing fish pond bottom dredging device for marine fishery cultivation cannot remove the stubborn sludge at the bottom of the fish pond, and the dredging effect poor
