Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and in particular to a harvesting device and method for indoor factory-style aquaculture of sea cucumbers. Background Technology

[0002] Sea cucumbers are large benthic animals with soft bodies and abundant body fluids. They mainly inhabit marine sediments with sandy or muddy bottoms, and their burrows are U-shaped, reaching depths of 5-30 cm. For sea cucumbers inhabiting natural seabed mud and sand, traditional harvesting equipment and methods are mainly based on the depth of the water in their habitat, selecting different harvesting equipment accordingly.

[0003] For sea cucumbers that inhabit the intertidal mud and sand bottom, a patented sea cucumber trapping tube (patent number 202111601738.X) uses a vacuum tube-type harvesting device composed of components such as a cylinder, push-pull rod, and piston. It aims at the sea cucumber holes on the intertidal mud and sand and repeatedly pumps air to extract the sea cucumbers and mud and sand for harvesting. However, the harvesting efficiency is low, and the harvested sea cucumbers are easily broken and disintegrated.

[0004] For areas where the tide cannot recede to expose the beach, a patented sea cucumber harvesting vessel (patent number 202010563600.4) is invented. The main principle is to use the hull on the water surface and underwater to use a towing bracket and its connected high-pressure nozzles to use high-pressure water flow to disperse sediments such as mud and sand on the seabed. The sea cucumbers and mud and sand enter the collection net behind them. The mud and sand are removed by the separation effect of the net, and the sea cucumbers are harvested. The disadvantages are that the equipment is complex and costly, and the high-pressure water gun can easily cause damage to the seabed and break the sea cucumbers, which also has a certain impact on the ecological environment.

[0005] For sea cucumbers that briefly float in seawater, a sea cucumber harvesting device (patent number 202410410840.9) uses a harvesting frame, a float, a fishing net, and an opening and closing component to form a double-layered net harvesting device to harvest sea cucumbers that float in the water with the ocean current. The disadvantage is that it cannot harvest sea cucumbers buried in mud and sand.

[0006] The aforementioned patents have innovated harvesting equipment for sea cucumbers in different ecological environments. However, no reports have been found regarding harvesting devices for sea cucumbers cultured in indoor factory-style cement ponds. Sea cucumber culture in factory-style cement ponds has significantly different ecological characteristics compared to the aforementioned natural ecological environments and sea cucumber lifestyles. Firstly, the sea cucumbers inhabit artificially filled sand and mud at a depth of 10-20 cm. Secondly, the water depth and level can be artificially controlled within the cement, and the density of sea cucumbers is more than 10 times higher than in the natural environment. These differences in culture and environment mean that the harvesting methods in existing patents are not suitable for harvesting sea cucumbers cultured in factory-style cement ponds. Therefore, a harvesting device is needed specifically for sea cucumbers cultured in indoor factory-style cement ponds to meet the demand for efficient harvesting. Summary of the Invention

[0007] The purpose of this invention is to provide a harvesting device and method for indoor factory-style sea cucumber farming, which solves the shortcomings of the prior art mentioned in the background section and meets the high-efficiency harvesting requirements in factory-style cement pond sea cucumber farming.

[0016] By using a combination of a rotating sorting mesh belt and a multi-nozzle flushing pipe, the mud and sand are flushed through the multi-nozzle flushing pipe during the transport of the mixture of mud and sea cucumbers, and the gaps in the rotating sorting mesh belt are used to separate the mud and sand from the sea cucumbers, effectively reducing the sea cucumber damage rate and ensuring the integrity and survival rate of the harvested sea cucumbers.

A collection net and an elevator are set at the end of the rotating sorting mesh belt, which has two harvesting methods: in-situ collection and lifting collection. The appropriate harvesting method can be selected according to the actual harvesting needs. Attached Figure Description
