Abstract
The utility model relates to digging teeth, in particular to digging teeth which are used on a mine machine and coated with an alloy layer on top. The digging teeth consist of a carbon steel digging teeth body and an alloy teeth top coating. The carbon steel digging teeth body comprises a tooth column and a tooth top. The alloy teeth top coating covers the tooth top. The utility model solves the problems of infirm inlay and thin metal surface coating alloy layer for the prior art and overcomes the defect of short service life for the prior art.
Description
Technical field
The utility model relates to a kind of tooth that digs, and particularly relates to the tooth that digs of top coating alloy-layer that a kind of mining machinery uses.
Background technology
Mechanized is brought into use in increasing mine, promotes the coefficient of mining in mine, eliminates safe hidden trouble.Mechanization degree in mines such as coal, copper mine, zinc ores promotes greatly, and the market capacity of mine mechanism is strengthened greatly.Excavator claims excavation machinery again, is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload earth moving plant to rickyard of packing into.The material that excavates mainly is soil and the rock behind soil, coal, silt and the pre-pine of process.From the development of engineering machinery in recent years, the development of excavator is very fast relatively, and excavator is as one of topmost engineering machinery type in the engineering construction.The equipment of excavator is a device of directly finishing mining task, and three parts are hinged forms by swing arm, dipper, scraper bowl etc. for it.Swing arm rises and falls, dipper stretches and the control of reciprocating double-action hydraulic cylinder is all used in the scraper bowl rotation.In order to adapt to the needs of various different construction operations, hydraulic crawler excavator can be equipped with multiple equipment, as several work facility such as excavation, lifting, loading, smooth, clamp, soil-shifting, jump bits.And scraper bowl dig tooth, be bucket tooth, teeth again, be the functional component that directly acts on mineral, rock, in order to adapt to different operating conditions, dig tooth and be generally monolithic carbon steel or alloy steel material.Because alloy steel price expensive and dig the tooth toughness reguirements, if tumble in alloy steel at the top that carbon steel digs tooth, not only economy but also can satisfy instructions for use.Therefore, the tooth that digs that head is inlayed alloy occurred, still, the mode of inlaying usually all is mechanical type or is welded to connect with alloy electrode that using the long time, the alloy of inlaying will loose or dislocation.
Summary of the invention
The purpose of this utility model provides a kind of tooth that digs, and the tooth that digs of top coating alloy-layer that a kind of mining machinery uses particularly is provided.The utility model has solved prior art and has inlayed problem insecure, that metal surface coated alloy layer is thin, has remedied prior art short deficiency in application life.
A kind of tooth that digs of the present utility model digs the tooth body and carbide button top coat two parts are formed by carbon steel, and carbon steel digs the tooth body and comprises tooth post and tooth top, and the carbide button top coat is coated on the tooth top.
As optimized technical scheme:
Wherein, aforesaid a kind of tooth that digs, described carbide button top coat thickness is 5～25mm.
Aforesaid a kind of tooth that digs, described coating are that meltblown layer coats.Described melting and spraying is meant that the oxy arc rifle is positioned at the tooth top top that carbon steel digs the tooth body, the tooth top surface that the front end heating carbon steel of oxy arc digs the tooth body, next-door neighbour's oxy arc rifle below is provided with a spray gun, the coating metal powder is from the spray gun ejection and through the oxy arc heating and melting, the coating metal powder of last fusion drops on the tooth top surface that the carbon steel of preheating digs the tooth body, and successively piles up.
The beneficial effects of the utility model are:
A kind of tooth that digs of the present utility model, the alloy and the workpiece body of hard wear resistant merge fully, and be rational in infrastructure, long service life, applied range.A kind of head construction that digs tooth of the present utility model can be used for the rock drill head of engineering mining machinery equally.

Fig. 1 is a kind of structural representation that digs tooth of the utility model
Fig. 2 is that a kind of carbon steel that digs tooth of the utility model digs tooth body schematic diagram
Wherein 1 is that to dig tooth body 2 are carbide button top coats to carbon steel
1.1 be that tooth post 1.2 is tooth tops
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention.
As illustrated in fig. 1 and 2, it is a kind of tooth that digs of the present utility model, it is the tooth that digs of the top coating alloy-layer used of a kind of mining machinery, dig tooth body 1 and carbide button top coat 2 two parts are formed by carbon steel, carbon steel digs tooth body 1 and comprises tooth post 1.1 and tooth top 1.2, and carbide button top coat 2 is coated on the tooth top 1.2.The material of carbide button top coat 2 can adopt alloy materials such as diamondite usually.
Wherein, described carbide button top coat 2 thickness are 5～25mm.Described coating is to adopt the mode that melts and sprays, described melting and spraying is meant that the oxy arc rifle is positioned at tooth top 1.2 tops that carbon steel digs tooth body 1, the front end heating carbon steel of oxy arc digs tooth top 1.2 surfaces of tooth body 1, the rifle mouth of next-door neighbour's oxy arc rifle is provided with a spray gun, the coating metal powder is from the spray gun ejection and through the oxy arc heating and melting, the carbon steel that the coating metal powder of last fusion drops on preheating digs tooth top 1.2 surfaces of tooth body 1, and successively piles up.
Through evidence, a kind of tooth that digs of the present utility model has solved prior art really and has inlayed problem insecure, that metal surface coated alloy layer is thin, has remedied prior art short deficiency in application life.
Claims (3)
