The grab bucket type mud sampling device comprises a support, a mud sampler and the thruster, the mud sampler comprises a first jaw and a second jaw which are rotatably connected to the two sides of a middle shaft respectively, mud sampling is achieved through relative opening and closing of the first jaw and the second jaw, the mud sampler is fixedly connected with the support, and the thruster is fixedly connected with the support. The propeller is installed on the support, and the propeller is arranged in the mode that the direction of propelling force of the propeller to the support faces the opening direction when the first jaw flap and the second jaw flap are opened. After the grab bucket type mud sampling device is provided with the propeller, once the propeller is started, downward thrust can be given to the mud sampler to prevent the mud sampler from floating up possibly when the mud sampler touches a hard mud layer, so that it is guaranteed that the grab bucket can be kept at a low position for mud sampling, and mud sampling of the grab bucket is more full.
本发明涉及一种具有推进器的抓斗式采泥装置,包括支架、采泥器和推进器,其中采泥器包括分别可转动连接在中轴的两侧的第一颚瓣和第二颚瓣,通过第一颚瓣和第二颚瓣的相对张开和闭合实现采泥,采泥器与支架固定连接,推进器安装在支架上,推进器被设置为:推进器对支架的推进力方向朝着第一颚瓣和第二颚瓣张开时的开口方向。本发明的抓斗式采泥装置在安装有推进器之后,推进器一经启动,就可以给予采泥器向下的推力,以阻止采泥器在碰到较硬的泥层时可能出现的上浮运动,从而保证抓斗能够维持在较低的位置进行采泥,让抓斗采泥采得更满。
