Triangular cutting edge tooth for dredging rake head

The invention relates to a triangular cutting edge tooth for a dredging rake head, and belongs to the technical field of dredging engineering. The triangular cutting edge tooth for the dredging rake head is characterized in by being composed of a tooth root, a tooth stem and a tooth edge, wherein the tooth root is used for being installed on a rake head tooth seat of a rake suction boat, and the tooth edge is a triangular cutting edge tooth. The triangular cutting edge tooth has better cutting effect on compact soil compared with other rake teeth of the same series, so that the dredged soil can be fully separated into strips before being excavated and conveyed by the dredging rake head, and the excavation efficiency of the soil is fully improved; and the relatively thin tooth edge and a relatively small tooth head are used for reducing the possibility that clay blocks the rake tooth, so that the negative influence caused by the fact that high-pressure water blowing is not opened so asto ensure the concentrati
