摘要
针对目前池塘拖网捕鱼作业完全靠人力,工作效率低的问题。通过在池塘两侧设置网具引导钢丝绳,利用液压绞车及拖引装置实现连续拖网的方法,开发了一套池塘机械拖网捕鱼系统。试验结果为:拖网系统在规格为50m×100m池塘进行机械拖网试验,拖网速度为10m/min,拖网人员由12人减少至5人,拖网捕鱼效率约64.8%。机械拖网大幅减少了作业人数,运行稳定,适用于各类矩形池塘的捕捞作业。
To solve the problem of pond harvest work entirely depending on manpower nowadays,a mechanized harvest system for fishpond was developed.This system was designed by locating steel wire rope on both sides of the pond to guide netting gear,making use of hydraulic winch and trawl apparatus to accomplish the continuous trawl.According to the mechanical trawl experimentation carried out in the pond sized 50 m×100 m,the result showed that the velocity of trawl was 10 m/min,and the number of trawl staffs were reduced from 12 to 5,the efficiency of trawl fishing was approximately 64.8%.It was concluded that this system can reduce the number of labors,run smoothly,and it is applicable for all kinds of harvesting operations in rectangular ponds.
