Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

Example (b):

as shown in fig. 1-4, a digging cutter head comprises a triangular prism-shaped cutter body 6, a cutter handle 8 is integrally formed on a first side surface of the cutter body 6, a limiting ring 7 is arranged on the side surface of the cutter handle 8 around the circumference of the axial lead of the cutter handle, the cutter handle 8 is prevented from falling off by the limiting effect of the limiting ring 7, the edge of the cutter body 6 opposite to the first side surface is a cutter edge 3, a plurality of reinforcing teeth 4 are distributed on the cutter edge 3 at intervals along the extending direction of the cutter edge 3, a mounting hole 9 is arranged at the position of the cutter edge 3, the tail ends of the reinforcing teeth 4 are arranged in the mounting hole 9 and are in interference fit with the mounting hole 9, the front ends of the reinforcing teeth 4 are positioned outside the mounting hole 9, a cutting edge can also be arranged at the front end of the reinforcing teeth 4 to improve the digging capacity of the reinforcing teeth 4, depressed parts 2 are arranged on a second side surface and a third side surface of the cutter body 6, one side surface of the depressed part 2 adjacent to the reinforcing teeth 4 extends to the cutter edge 3, the thickness of the cutter body 6 can be reduced by the depressed parts 2, the protruding support bar 1 that forms in both sides of depressed part 2, support bar 1 distributes along the direction of the edge of perpendicular to cutter body 6, and support bar 1 and cutter body 6 integrated into one piece are provided with a plurality of cylindrical anticollision pieces 5 on the support bar 1, and anticollision piece 5 makes by carbide steel with strengthening tooth 4 to improve anticollision piece 5 and strengthen the intensity of tooth 4.
