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, a high-frequency breaking hammer and an engineering trolley, an inserting groove is formed in the rear end of a tooth top body of the bucket tooth, the tooth top body is further provided with a liquid outlet channel extending to the surface of the tooth top body from the interior of the inserting groove, and a containing groove is formed in the front portion of the tooth top body; the tooth tip further comprises an attaching block connected with the tooth tip body, the attaching block is arranged in the containing groove, and a spraying opening communicated with the liquid outlet channel is formed in the edge of the attaching block. Shielding protection can be provided for the liquid outlet of the liquid outlet channel through the attaching block, and the liquid outlet is prevented from being blocked due to direct contact with objects such as soil and gravel. Meanwhile, liquid (such as water) is supplied to the attaching block through the liquid outlet channel and is sprayed outwards through the spraying openings in the attaching block to form a water curtain or drop mist which is combined with dust in the air, so that the dust quickly falls to the ground after absorbing water, and the dust in the air is reduced.

本发明涉及斗齿领域，具体涉及到一种斗齿齿尖、斗齿、高频破碎锤及工程台车，其中，斗齿的齿尖本体的后端具有插槽，所述齿尖本体还具有从插槽内延伸到齿尖本体表面的出液通道，所述齿尖本体的前部设有容纳槽；还包括与所述齿尖本体相连接的贴块，所述贴块设于所述容纳槽内，并在所述贴块的边缘设有与所述出液通道连通的喷淋口。本发明可以通过贴块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贴块并通过贴块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。
