Abstract
The utility model relates to a novel cutting tooth which comprises a cutting tooth body; a hard alloy cutter bit is welded at the front end of the cutting tooth body; and a ceramic sleeve is sheathed on the outer surface of the front part of the cutting tooth body. In the cutting tooth, a high-strength high-tenacity ceramic material is adopted for manufacturing the novel cutting tooth to a sleeve shape, and the ceramic sleeve is sheathed on the outer surface of the common low alloy steel cutting tooth body so as to effectively protect the cutting tooth from being abraded fast. The novel cutting tooth can effectively solve the problem of abrasion of the cutting tooth body, prevents the cutting tooth body from being abraded too fast and the cutter bit from falling too early, and prolongs the service life of the cutting tooth greatly. The ceramic sleeve is additionally arranged on the cutting tooth body, although the cost of the cutting tooth is improved partly, and the servile life of the cutting tooth can be prolonged by more than three times, so that the novel cutting tooth has extremely high cost performance.

As everyone knows, the hardness height of pottery, abrasion resistance is good, but more crisp.The intensity and the toughness of common ceramic materials are not high enough, can not be applied on the pick and work under the working environment of digging high impact forces.Since the progress of ceramics research, the new ceramic material rapid technological improvement, and the high-intensity high-tenacity pottery occurs and uses increasingly extensive.So we consider to adopt the pottery of high-intensity high-tenacity to be installed on the pick body, form one " armor ", are used for protecting the pick body to avoid excessive wear.In the utility model, ceramic materials has been " armor " effect, rather than is used for cutting as some sintexes on the market.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of novel pick being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of novel pick includes the pick body, and the front end of pick body is welded with carbide bit, and the external surface in pick body front portion is with a ceramic sleeve.
Preferably, described ceramic sleeve adopts the high-intensity high-tenacity ceramic materials to make.
Preferably, the end of described carbide bit outwards outstanding and be positioned at described ceramic sleeve top edge the top and block this edge.
Preferably, described ceramic sleeve is fixed on the described pick body by rivet.
The utility model adopts the high-intensity high-tenacity ceramic materials to make sleeve-shaped, and ceramic sleeve is enclosed within ordinary low-alloy steel pick external surface, protects the pick body not worn and torn fast effectively.The effect that effect that pottery plays in the utility model and the pottery on the sintex play is different; pottery in the sintex is used for cutting; pottery in the utility model is to be used for protecting the pick body to avoid wearing and tearing, plays the effect of " armor ".In the utility model, cutting coal and rock still are to use carbide bit.This utility model can effectively solve pick body wear problem, prevents that pick body rapid wear, cutter head from coming off too early, increases the application life of pick greatly.Install ceramic sleeve additional for the pick body, the part though the cost of pick can rise, can improve more than 3 times the application life of pick, has very high cost performance.
