Desilting device for aquaculture pond

Abstract

The invention discloses a desilting device for an aquaculture pond. The device comprises a ship body, a silt pump, an oxygenation pump and an electric telescopic rod; the electric telescopic rod is mounted at the tail of the ship body; a sliding rod slidably sleeves the bottom of the electric telescopic rod and is connected with a roller; one side of the lower portion of the sliding rod is connected with an air outlet pipe, the top of the air outlet pipe is connected with an oxygenation pump through an oxygenation pipe, the other side of the lower portion of the sliding rod is connected with apush plate, blades are installed on the inner side wall of the push plate, and a silt suction disc is arranged between the blades and the inner wall of the push plate and connected with the sliding rod; and the slit suction disc is connected with the silt pump through a silt suction pipe, and the slit pump is connected with a receiving box. The electric telescopic rod is started, the rollers extend into sludge, the ship body moves on the water surface to drive the sliding rods and the rollers to move, the push plate is turned over to gather the sludge inwards, the slit pump pumps water in thesludge into the receiving box through the slit suction pipe and the slit suction disc; after the sludge falls into the receiving box, the water in the sludge is returned to the pond, and meanwhile, after the sludge is turned over by the push plate, the oxygenation pump introduces oxygen into the bottom of the pond.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an aquaculture pond dredging device. Background technique [0002] During aquaculture, due to the continuous accumulation of feces, excrement, remains, residual bait and fertilization of aquaculture animals in the aquaculture pond, as well as the continuous deposition of surface impact objects, the deposited organic matter is decomposed by microbial fermentation to form a large amount of humus, which infiltrates with the bottom surface of the pond The soil is mixed together to form a certain thickness of silt at the bottom of the pool. When the silt is 10-15cm in size, it can play a role in maintaining fertilizer, supplying fertilizer and buffering water quality. However, too much silt will lead to hypoxia in the pool water and toxic substances in the pool water. The disadvantages of harmful bacteria such as the increase of harmful bacteria in the pond water, etc., ...

[0002] During aquaculture, due to the continuous accumulation of feces, excrement, remains, residual bait and fertilization of aquaculture animals in the aquaculture pond, as well as the continuous deposition of surface impact objects, the deposited organic matter is decomposed by microbial fermentation to form a large amount of humus, which infiltrates with the bottom surface of the pond The soil is mixed together to form a certain thickness of silt at the bottom of the pool. When the silt is 10-15cm in size, it can play a role in maintaining fertilizer, supplying fertilizer and buffering water quality. However, too much silt will lead to hypoxia in the pool water and toxic substances in the pool water. The disadvantages of endangering the cultured products such as the increase of harmful bacteria in the pond water, etc., so it is necessary to regularly desilt the aquaculture pond. The existing dredging methods are to manually clean up the water in the aquaculture pond or directly use the silt pump to remove the silt. However, manual dredging after draining the water is time-consuming and laborious, and wastes water resources, and directly using the silt pump to extract the silt cannot control the degree of silt extraction, resulting in excessive silt extraction. Therefore, we propose a desilting device for aquaculture ponds. solve the above problems
