QIU ZHANGLING / FENG LIBO / WEI XIHAO / TIAN FUQIANG

The invention relates to the field of bucket teeth, in particular to a bucket tooth top, a bucket tooth and an engineering trolley, an inserting groove is formed in the rear end of a tooth top body of the tooth top, and the tooth top body is further provided with a liquid outlet channel extending to the surface of the tooth top body from the inserting groove; the tooth tip further comprises a covering piece connected with the tooth tip body. A spraying opening communicated with the liquid outlet channel is formed in the edge of the covering piece. The liquid outlet of the liquid outlet channel can be shielded and protected through the shielding piece, and the liquid outlet is prevented from being blocked due to direct contact with objects such as soil and gravels. Meanwhile, liquid (such as water) is supplied to the covering piece through the liquid outlet channel and sprayed outwards through the spraying openings in the covering piece to form a water curtain or drop mist which is combined with dust in the air, so that the dust rapidly falls to the ground after absorbing water, and the dust in the air is reduced. According to the invention, the effects of dust falling and dust removal are achieved through the combination of various means.

本发明涉及斗齿领域，具体涉及到一种斗齿齿尖、斗齿及工程台车，其中，齿尖的齿尖本体的后端具有插槽，所述齿尖本体还具有从插槽延伸到齿尖本体表面的出液通道；还包括与所述齿尖本体相连接的遮盖件；所述遮盖件的边缘设有与所述出液通道连通的喷淋口。本发明可以通过遮盖件来为出液通道的出液口提供遮挡保护，避免出液口直接与泥土、碎石等物体接触而被堵塞。同时，将液体(例如水)通过出液通道供给到遮盖件并通过遮盖件上的喷淋口向外喷淋形成水幕或滴雾并与空气中的粉尘相结合，使粉尘吸水后快速降落到地面，从而减少空气中的粉尘。本发明通过以上各种手段的结合以达到降尘、除尘的效果。
