The invention relates to the technical field of crane grab buckets, and particularly discloses a bucket type grab bucket based on a crane, which comprises a stand column, a grab bucket and a baffle plate, the lower end of the stand column is connected with a fixing base, the two baffles are located in the grab bucket and arranged on the fixing base, the ends, close to the grab bucket, of the baffles are rotationally connected with scraping plates, the two ends of each scraping plate are the material scraping end and the collision clearing end respectively, the collision clearing end is provided with a collision clearing mechanism, and the collision clearing mechanism comprises a first top plate, a second top plate and a force storage unit. According to the bucket type grab bucket based on the crane, viscous materials at the bottom and on the two sides of the inner cavity of the grab bucket can be removed in the discharging and swinging process of the grab bucket under the cooperation of the scraping plates and the baffles, when materials on the inner wall of the grab bucket are difficult to remove, the scraping ends of the scraping plates are overturned to the collision removing ends to remove the materials, and therefore the inner wall of the grab bucket is cleaned, and the working efficiency is improved. And meanwhile, the scraper is rotatable, so that the two ends of the scraper can clean the inner wall of the grab bucket, and the service life of the scraper can be prolonged.
本发明涉及起重机抓斗技术领域,具体公开了一种基于起重机的斗式抓斗,包括立柱、抓斗和挡板;立柱的下端连接有固定座,挡板具有两个,两个挡板分别位于抓斗内,挡板设置在固定座上,挡板靠近抓斗的一端可转动连接有刮板,刮板两端分别为刮料端和清撞端,清撞端设置有清撞机构,清撞机构包括第一顶板、第二顶板和蓄力单元;本发明的基于起重机的斗式抓斗通过刮板和挡板的配合下在抓斗放料摆动过程中可以对抓斗内腔底部和两侧上的粘稠物进行清除,其中,在抓斗内壁上的物料难以清除时,刮板的刮料端翻转至清撞端进行清料,从而对抓斗的内壁清理,同时刮板可转动能够使得刮板的两端都能够对抓斗的内壁起到清理的效果,可以增加刮板的使用寿命。
