Abstract

The utility model relates to a sparkless cutting pick, comprising a pick handle tail part, a clamping ring groove, a pick handle, a pick head, a cladding layer and hard alloy, wherein the pick head is connected with the pick handle which is connected with the pick handle tail part by the clamping ring groove; and the pick head is internally provided with the hard alloy. The sparkless cutting pick is characterized in that the outer layer of the pick head is provided with one cladding layer which is a ceramic alloy powder melting layer with the thickness of more than 1mm. The sparkless cutting pick has the benefits that: by adopting the ceramic alloy powder melting layer, the sparkless cutting pick effectively limits the generation of spark, is beneficial to safety production of coal mine, has strong mechanical property and anti-friction property and long service life, and improves the working efficiency.

Description

The no-spark pick

Technical field

The utility model relates to coal industry mining machinery consumption part, and specifically a kind of abrasion resistance is strong, do not produce the no-spark pick of spark during with the rock collision friction.

Background technology

At present, pick mechanical property, the friction resistant performance that the coal industry mining machinery is used in the prior art is poor, application life short, a large amount of sparks can occur with the lithosphere friction especially in use, running into has gas and ventilation condition condition of poor, very easily causes security incident.

Summary of the invention

It is strong that the purpose of this utility model provides a kind of abrasion resistance, do not produce the no-spark pick of spark during with the rock collision friction, the technical scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises the tooth handle tail, the jump ring groove, the tooth handle, the tooth head, cladding layer, carbide alloy, the tooth head is connected with the tooth handle, the tooth handle is connected with the tooth handle tail by the jump ring groove, be provided with carbide alloy in the tooth head, the skin that it is characterized in that the tooth head is provided with one deck cladding layer, described cladding layer is that a layer thickness is the ceramal powder crucible zone more than a millimeter, and the outer wall of described tooth head is the circular-arc of evagination at the position around carbide alloy.Cladding layer adopts the plasma melting coating technique; with alloy powder or ceramic powders with the tooth head surface rapidly heating and melt, mix, spread, react, solidify, thereby self-excitation cooling back forms hard wear resistant, impact-resistant cladding layer; cladding layer has effectively been protected hard alloy cutter bit; prolonged the application life of pick; ceramal powder crucible zone and rock collision friction do not produce spark substantially simultaneously, have improved the security performance of channel of coal mining working surface.

The beneficial effects of the utility model are, this device adopts ceramal powder crucible zone, effectively suppress spark and produce, and are beneficial to Safety of Coal Mine Production, and mechanical property, strong, the long service life of friction resistant performance have improved operating efficiency.
