The invention relates to the technical field of grab buckets, in particular to a hoisting machinery improved grab bucket which comprises a fixing plate, a first grab bucket, a second grab bucket, a driving mechanism and an auxiliary mechanism. The first grab bucket and the second grab bucket cooperate with each other to grab a designated position, then river water flows back into a river through a draining groove in the first grab bucket and a sand leaking groove in the second grab bucket, and sand or soil in a closed area of the two second grab buckets leaks to the first grab bucket through the sand leaking groove in the upward moving process of the two second grab buckets; therefore, sand or soil can be subsequently placed at a specified position, and stones can also be placed at the specified position through operation of the driving mechanism, so that subsequent independent transportation or use of the stones, the sand and the like is facilitated; and a stirring plate I and a stirring plate II are matched with each other to slowly stir a mixture such as stones and sand or soil in the grab bucket II, so that substances such as the sand and the soil can conveniently fall onto the grab bucket I through a sand leaking groove, and the sand and the soil can be conveniently separated subsequently.
本发明涉及抓斗技术领域,具体为一种起重机械改进型抓斗,包括固定板、抓斗一、抓斗二、驱动机构和辅助机构。本发明中首先由抓斗一和抓斗二相互配合完成对指定位置的抓取,之后河水通过抓斗一上的沥水槽以及抓斗二上的漏沙槽流回河中,两个抓斗二合拢区域内的沙子或者泥土在两个抓斗二上移的过程中通过漏沙槽漏出至抓斗一上,故后续能将沙子或者泥土放置在指定位置的同时能通过驱动机构作业将石块也能放置在指定位置,即便于后续对石块、沙子等的单独运输或者使用,以及搅拌板一和搅拌板二相互配合对抓斗二内的石子以及沙子或者泥土等混合物进行缓速搅拌,便于沙子以及泥土等物质通过漏沙槽掉落至抓斗一上,即便于后续对二者进行分离处理。
