Conveying chain rake type little clam catching device

Abstract

The invention provides a conveying chain rake type little clam catching device which comprises a frame body. The catching device is characterized in that a waterproof motor is arranged in the frame body, the working end of the waterproof motor is connected with two first chain wheels supported in the frame body in a rotating mode and symmetrically arranged, the first chain wheels are connected with second chain wheels through transmission chains, the second chain wheels can drive a first operation shaft to rotate, a second operation shaft is supported in the frame body in a rotating mode, the first operation shaft and the second operation shaft are connected through conveying chains, a plurality of supporting rods are arranged between the two conveying chains in parallel, a plurality of elastic rake teeth are uniformly distributed on the supporting rods, a hard collecting net is arranged behind the second operation shaft, a flexible collecting net is connected to the portion, behind the hard collecting net, of the frame body, a plurality of guide plates are uniformly distributed at the bottom of the frame body, motion trails of the tail ends of the elastic rake teeth protrude out of the bottom face of the frame body, an arc-shaped plate is arranged at the front end of the frame body, and a net is arranged outside the frame body.

Description

technical field [0001] The invention relates to a clam collecting and catching device, in particular to a conveying chain rake type clam collecting and catching device. Background technique [0002] As an important growth point of the marine economy in the northern Yellow Sea and Bohai Sea region of my country, shellfish bottom-sowing aquaculture has played an important role in the development of the local economy. At the same time, it also puts forward higher requirements for bottom-sowing and aquaculture equipment. At present, artificial breeding of tidal flat-buried shellfish has been carried out, including Philippine clams, rainbow clams, meretrix meretrix, green clams, mud clams, razor clams, mud snails, and Xishi tongue, etc. Due to the low cost, good benefits, and ecological Therefore, its aquaculture scale is also increasing year by year, and it is becoming more and more important to the sustainable development of the mariculture industry and regional economy. When ...

AI Technical Summary

Problems solved by technology

When harvesting shellfish cultured on tidal flats, traditional methods generally adopt manual operations such as clam raking, beach turning, and digging, which cannot meet the needs of large-scale farming production of clams.

At present, high-pressure water pump water spraying and high-power hydraulic harvesting are mainly used in production. However, because this harvesting method will stir up a large amount of sediment during operation, it is easy to cause clams to choke into the sediment and suffocate to death, which seriously affects the quality of clams.

Moreover, the hydraulic harvesting method will also cause a large amount of sediment loss in the breeding area, causing serious damage to the breeding ecological environment and affecting the sustainable development of the clam farming industry.
