when the existing cutting pick for the rock stratum is used, the front end of the pick body head is easy to wear, and the wear of the pick body head can lead to the falling off of the hard alloy head, so that the service life of the cutting pick is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a pick to the stratum.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a pick to stratum, includes the pick body head, the overhead ladder face of having seted up of pick body, be provided with wear-resisting piece on the ladder face, the mounting hole has been seted up at the top of pick body head, the bottom fixed mounting of pick body head has the tooth handle, the ring channel has been seted up on the tooth handle, the inside fixedly connected with carbide head of mounting hole.
Preferably, the material of the wear-resistant block is the same alloy as the material of the hard alloy head.
Preferably, the wear-resistant block is formed by sintering warm-pressing forging.
Preferably, the upper end of the mounting hole is conical, and the lower end of the mounting hole is cylindrical.
Preferably, the groove depth of the annular groove is 3-3.5 mm.
Preferably, the hard alloy head is matched with the mounting hole, and the hard alloy head is fixedly connected with the mounting hole through brazing of copper-zinc brazing filler metal.
The utility model has the advantages of it is following:
this pick to stratum through setting up wear-resisting piece, wear-resisting piece is fixed on the ladder face of pick body head through sintering warm pressing forging forming's technology, has increased the density of wear-resisting piece to improve wear-resisting piece intensity, carried out abundant protection to the pick body head, the life of extension pick has reduced in the use because the wear of pick body head front end is serious, leads to the probability that the carbide head drops.
