流网渔业在海淡水渔业中占有重要地位。但目前仍采用原始的人力扠网方式,生产效率低、劳动强度大、而且极不安全。广大渔工渔民迫切要求实现流网机械化。1978年以来国内相继造出几种流网机,但由于经济效益和使用性能诸因素还没能迅速推广。为了研制结构简单合理、操作方便省力、体积小重量轻、节约能源、性能完善的流网机,本机于一九八○年
Net-flow fisheries hold an important place in the sea-freshwater fisheries. However, the original manpower fork netting method is still used at present, which has low production efficiency, labor intensity and is extremely unsafe. The majority of fishermen and fishermen urgently required to achieve flow mechanization. Several domestic flow net machines have been built in China since 1978, but due to various factors such as economic benefits and serviceability, they have not been able to be promoted rapidly. In order to develop a simple and reasonable structure, easy operation and labor-saving, small size, light weight, energy saving, perfect performance of the flow network machine, the machine in 1980
