一种安装在船侧的螃蟹抓捕装置
本专利技术涉及渔具
,特别是涉及一种安装在船侧的螃蟹抓捕装置。
技术介绍
河蟹也叫“螃蟹”和“毛蟹”,头部和胸部结合而成的头胸甲呈方圆形,质地坚硬。身体前端长着一对眼,侧面具有两对十分坚锐的蟹齿。螃蟹最前端的一对附肢叫螯足,表面长满绒毛;螯足之后有4对步足,侧扁而较长;腹肢已退化。河蟹的雌雄可从它的腹部辨别:雌性腹部呈圆形,雄性腹部为三角形。河蟹的生命是短暂的,在它生活史中历经蚤状幼体、大眼幼体,幼蟹和成蟹等几个阶段,一生中需要幼体5次蜕皮成为大眼幼体,再经13-15次蜕皮成为成蟹,它一生只有一个生殖周期,繁殖结束生命也就终止,一般来说,河蟹的寿命为1-3周龄。随着生活水平的提高,食用螃蟹也越来越多,在捕抓野生或是工人养殖的螃蟹时,为防止螃蟹钳爪和爪趾夹伤和抓伤人员,需要设计出螃蟹捕抓工具,利于螃蟹的捕抓。
技术实现思路
本专利技术的目的是针对现有问题,提供了一种安装在船侧的螃蟹抓捕装置。本专利技术是通过以下技术方案实现的:一种安装在船侧的螃蟹抓捕装置,包括支架,所述支架的动板上安装气缸,气缸的伸缩杆贯穿动板后其端部螺纹连接推拉杆上端,推拉杆设置在柄套内,柄套下端一体连接罩壳,所述推拉杆下端置于罩壳的内顶部并呈三角均匀固接铰链座,铰链座通过销轴连接爪齿上钝端,爪齿下尖端伸出到罩壳外,爪齿外弧面一体连接滑轨,滑轨卡接滑块的槽,滑块间隔固接在罩壳内,所述推拉杆下端还安装有摄像头。作为对上述方案的进一步改进,所述的支架由固定板架、定轨、动轨、动板组成,所述的固定板架由立板一侧面下部水平连接平板,平板与立板间前后两侧连接加强板,所述 ...
