The invention relates to the technical field of coal grab buckets, in particular to a self-lubricating coal grab bucket, which comprises a grabbing mechanism, a lifting mechanism, a self-lubricating mechanism and a self-lubricating mechanism, the sealing mechanism comprises a frame, a folding plate and a cleaning brush; the lubricating mechanism comprises an oil hole, a dust cover, lubricating oil and a push rod; the folding plates are driven to be folded and stretched in the moving process of the hopper body, coal is wrapped and sealed, coal ash and smoke are prevented from entering the rotating shaft to block the oil injection hole, meanwhile, coal ash is prevented from overflowing to pollute the environment, and the inner wall of the hopper body is cleaned through the brush plates arranged on the side faces of the folding plates while the folding plates stretch out and draw back. The coal ash on the inner wall of the brush bucket is cleaned and collected into the bucket body, meanwhile, overflowing coal ash is reduced, meanwhile, lubricating oil in the dustproof cover is driven to enter the oil hole while the grab bucket and the supporting rod rotate, automatic lubrication is achieved, and when the grabbing frequency of the grab bucket is higher, the lubricating oil injection amount is higher so as to adapt to the high-strength working condition, meanwhile, manual operation is reduced, and the working efficiency is improved. The working efficiency is improved.

    本发明涉及煤炭抓斗技术领域,特别是一种自动润滑的煤炭抓斗,包括抓取机构,包括有吊板、撑杆、转轴、斗体和提拉块;以及密封机构,包括框架、折叠板和清扫刷;以及,润滑机构,包括有油孔、防尘罩、润滑油和推杆;通过斗体运动过程带动折叠板折叠伸展,实现对煤炭的包覆封闭,防止煤灰烟尘进入转轴堵塞注油孔,同时也防止煤灰溢出污染环境,折叠板伸缩的同时通过设置在折叠板侧面的刷板对斗体内壁进行清扫,清扫刷斗内壁煤灰并收集进斗体内部同时也减少了外溢的煤灰,同时在抓斗与撑杆转动的同时驱动防尘罩内的润滑油进入油孔,实现自动润滑,当抓斗抓取频率越快,则润滑油注油量越高,以适应高强度工作条件同时减少人工操作,提高工作效率。
