The invention discloses a crane grab bucket. The crane grab bucket comprises a hoisting beam, wherein the tail end of the hoisting beam is connected with a hoisting suspension rope, the lower end of the suspension rope is connected with a sludge grab bucket in a suspended mode, and the sludge grab bucket can grab or release sludge; and while a left bucket cavity and a right bucket cavity are completely filled by the left part and the right part of a bracket respectively, sludge originally filling the left bucket cavity and the right bucket cavity is completely extruded by the left part and theright part of the bracket, so that the sludge releasing process of the sludge grab bucket is realized, and the sludge is prevented from being left in the left bucket cavity and the right bucket cavity due to the viscosity of the sludge.
本发明公开了一种起重机抓斗,包括起重梁,所述起重梁的末端连接有起重悬挂绳,所述悬挂绳的下端悬挂连接有淤泥抓斗,所述淤泥抓斗能将淤泥爪起和释放;左斗腔和右斗腔分别被支架左部和支架右部完全填充的过程中,原来填充在左斗腔和右斗腔内的淤泥被支架左部和支架右部完全挤出,从而实现淤泥抓斗释放淤泥的过程,从而避免因淤泥的粘性残留在左斗腔和右斗腔内。
