Abstract
The utility model discloses a scraper with a boss, and belongs to the technical field of agitator accessories. The scraper include a scraper body, a scraper handle, a scraper handle assembling hole and a scraper edge, and is characterized in that the reinforced boss is formed on the scraper edge. As the impacts of the material on the different parts of the agitator are different, the reinforced boss is arranged on the scraper edge; therefore, the service life of the common scraper in increased by 20% to 50%, not only can the service life of the scraper is prolonged and the frequent replacement of the scraper be avoided, but also the production efficiency is improved.
Description
Technical field
The utility model belongs to the mixer fitting field, more particularly, relates to a kind of mixer scraper with boss.
Background technology
Mixer is a kind of machine, especially a high-abrasive material factory commonly used in the present industry, and mixer is an equipment commonly used.Because workload is big especially, the blade wears of mixer is more serious, needs often to change, and not only influences the production of factory, has also wasted wide variety of materials; In addition, because the particularity of mixer, the material of the inside impacts maximum to the edge of a knife end of scraper during the mixer running, and the edge of a knife of scraper at first weares and teares often, will not change scraper when also wearing and tearing fully at other positions, has caused unnecessary waste.
One Chinese patent application number: the prior art patent document of 201010137857.X discloses a kind of scraper, and this scraper comprises scrapes cutter hub, and an end of scraping cutter hub is provided with scrapes the edge of a knife; The other end is provided with handle of a knife; The outer surface of scraping the edge of a knife is welded with one deck compound carbonizing chromium and niobium carbide alloy, scrapes the edge of a knife and all is wrapped in the alloy-layer, and the two sides of scraping cutter hub and handle of a knife are welded with latticed alloy; Latticed alloy connects with the alloy phase of scraping the edge of a knife, and the material of scraping cutter hub is manganese steel or ordinary carbon steel.With respect to prior art, this invention adopts manganese steel or ordinary carbon steel to make the matrix of scraper, and makes wearing layer at matrix surface welding compound carbonizing chromium and niobium carbide alloy, has improved the anti-wear performance of scraper.Though this invention has improved the chip resistant performance and the anti-wear performance of scraper, prolonged the service life of scraper, still do not solve at first wear problems of the scraper edge of a knife.
Summary of the invention
The technical problem that solves
Wearing and tearing at first to the existing scraper edge of a knife shortens scraper blade life, the problem of waste material, and the utility model provides a kind of scraper with boss.
Technical scheme
The utility model is realized through following technical scheme:
A kind of scraper with boss comprises cutter hub, handle of a knife, handle of a knife pilot hole, the edge of a knife, and the edge of a knife is positioned at the front end of cutter hub, and handle of a knife is positioned at the rear end of cutter hub, and the reinforcement boss is arranged on the described edge of a knife, and described reinforcement boss is cuboid or semicylinder.During mixer work, material at first impacts strengthening boss.Because the effect of boss increases the wearability of the edge of a knife.
Described reinforcement boss and cutter hub are an integral body of casting.Described cutter hub adopts 2 wear-resistant white cast with the reinforcement boss.Easy to process, moulding is easy, strengthens the heat treatment simultaneously of boss and cutter hub.
Described reinforcement boss is welded on the edge of a knife of cutter hub.Described cutter hub is manganese steel or ordinary carbon steel with strengthening the boss material.Strengthen boss and cutter hub and can adopt material different, can reduce material cost.
Described handle of a knife pilot hole has 2-4.Said handle of a knife pilot hole is used for cutter hub is fixedly mounted on mixer.
?
Beneficial effect
(1) the utility model is provided with a reinforcement boss on the edge of a knife; Because the effect of boss increases the wearability of the edge of a knife; So the scraper of the utility model has increased 20-50% doubly than the life-span of common scraper, has avoided the frequent replacing of scraper, has improved production efficiency;
(2) the utility model is simple in structure, is easy to make.
