The invention relates to the technical field of engineering machinery, in particular to a grab bucket and engineering machinery. The grab bucket comprises a support and a grab bucket body, and furthercomprises a slag removing part and an elastic piece, one end of the slag removing part can abut against the support when the grab bucket body is in an open state, the other end of the slag removing part extends towards the inner wall of the bucket tooth side of the grab bucket body, the other end of the slag removing part can abut against the lower surface of a shaft seat in the grab bucket body,and the part between the two ends of the slag removal part is hinged to the support; and one end of the elastic piece is connected with the support, the other end of the elastic piece is connected with the slag removing part, and the elastic piece is used for enabling the slag removing part to rotate around a hinged shaft in the direction close to the support in the grab bucket body opening process, so that the distance between the other end of the slag removing part and the inner wall of the bucket tooth side can be reduced. According to the grab bucket, in the process from closing to opening, the distance between the slag removing part and the inner wall of the bucket tooth side of the grab bucket is reduced, that is, the slag removing part can remove soil attached to the inner wall ofthe bucket tooth side in a large range.
本发明涉及工程机械技术领域,尤其是涉及一种抓斗及工程机械。抓斗包括支座和抓斗体,还包括清渣部和弹性件,清渣部的一端能够在抓斗体处于打开状态下与支座抵接,清渣部的另一端向抓斗体的带斗齿侧的内壁处延伸,且清渣部的另一端能够与抓斗体内部的轴座的下表面抵接,清渣部两端之间的部分与支座铰接;弹性件一端与支座连接,另一端与清渣部连接,弹性件用于使清渣部在抓斗体打开过程中绕铰接轴向靠近支座的方向转动,以使清渣部的另一端与带斗齿侧的内壁之间的距离减小。本发明提供的抓斗从闭合到打开的过程中,清渣部与抓斗的带斗齿侧的内壁之间的距离减小,即清渣部能够将带斗齿侧的内壁上附着的泥土进行大范围清理。
