According to the utility model, the diamond layers are brazed at the tooth head and the gauge position, so that the strength of the tooth head is increased, the thickness of the diamond layer on the tooth head is larger than that of the diamond layer at the gauge position, meanwhile, an annular groove is formed at the joint of the tooth head and the tooth seat, and a metal nickel layer is welded in the annular groove, so that the tooth head and the tooth seat are welded more tightly.
Description
Technical Field
The utility model relates to a coal mine machine. In particular to a diamond-inlaid wear-resistant cutting pick of an electroplating surface rotary excavator.
Background
The spinning machine pick is widely applied to the construction operation of bridges and tunnels, and mainly comprises two parts, wherein one part is a steel body, the other part is a pick head, the pick head is a hard alloy pick head welded on the head of the steel body, and in the actual operation process, the pick head can be worn frequently to shorten the service life of the pick, and in addition, the pick head is not firmly connected with a pick holder, so that the phenomenon that the pick head falls off frequently occurs.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model discloses a diamond-inlaid wear-resistant rotary excavating machine cutting pick for an electroplating surface, wherein diamond layers are brazed at a tooth head and a diameter-protecting position to increase the strength of the cutting pick, an annular groove is formed at the joint of the tooth head and a tooth holder, and a metal nickel layer is welded in the annular groove to enable the tooth head and the tooth holder to be welded more tightly.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides an electroplate table and inlay wear-resisting rotary excavating machine pick of diamond, includes tooth head, toothholder, tooth handle and cassette, the tooth head install in the recess of toothholder, the toothholder with cassette integrated into one piece, the top of toothholder has the gage position, the tooth head includes toper portion and installation handle, the installation handle holding is in the recess of toothholder, the equipartition has a plurality of archs on the surface of toper portion, the gage position with the diamond layer has been brazed on the surface of toper portion, the thickness of the surperficial diamond layer of gage position is 2.0-3.0mm, the thickness of the surperficial diamond layer of toper portion is 6.0-8.0 mm.
Preferably, the lower end edge of the conical part is provided with an upper annular groove, the upper end of the tooth holder is provided with a lower annular groove, and the tooth head and the tooth holder are connected by welding a metal nickel layer in the upper annular groove and the lower annular groove.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the diamond layers are brazed at the tooth head and the gauge position, so that the strength of the tooth head is increased, the thickness of the diamond layer on the tooth head is larger than that of the diamond layer at the gauge position, meanwhile, an annular groove is formed at the joint of the tooth head and the tooth seat, and a metal nickel layer is welded in the annular groove, so that the tooth head and the tooth seat are welded more tightly.
