The invention discloses a sediment conveying and grading mechanism and a drilling ship, and relates to the technical field of drilling ships. The sediment conveying and grading mechanism comprises a grading box which is provided with a feeding port; the impact plate is connected to the position of the feeding opening in a sliding manner; the screening plate is transversely and slidably connected into the grading box; the speed change mechanism comprises a driving wheel and a driven wheel which are rotationally connected to the grading box, a transmission belt is arranged between the driving wheel and the driven wheel, the driving wheel is rotationally connected with the impact plate, and the rotating stroke of the driven wheel drives the screening plate to linearly slide back and forth on the grading box; the impact plate is made to slide through the force generated when sediment impacts on the impact plate, and in the sliding process of the impact plate, the driving wheel and the driven wheel are driven to passively adjust the transmission ratio, so that rotation of the driven wheel is accelerated under the condition that the rotating speed of the driving wheel is certain; therefore, the reciprocating transverse movement speed of the screening plate is increased, and the grading efficiency is improved.

    本发明公开了一种泥沙输送分级机构及钻探船,涉及钻探船技术领域,一种泥沙输送分级机构,分级箱,其开设有投料口;冲击板,其滑动连接在投料口位置处;筛分板,其横向滑动连接在分级箱内;变速机构,其包括转动连接在分级箱上的主动轮和从动轮,主动轮和从动轮之间设置有传动带,主动轮与冲击板转动连接,从动轮转动的行程,驱使筛分板在分级箱上往复直线滑动;冲击板具有滑动行程和复位行程:通过泥沙冲击在冲击板上的力,使冲击板滑动,在冲击板滑动的过程中,驱使主动轮和从动轮被动式地进行传动比的调节,使主动轮在转速一定的情况下,加速从动轮的转动,从而加快筛分板往复横向移动的速度,提高分级效率。
