Abstract
The invention relates to a scraper, belonging to the technical field of a concrete mixer. The scraper comprises a scraper body, wherein one end of the scraper body is provided with a scraper edge, the other end of the scraper body is provided with a scraper handle, the outer surface of the scraper edge is welded with a layer of composite chrome carbide and niobium carbide alloy, the scraper edge is wholly packed in the alloy layer, the two side faces of the scraper body and the scraper handle are welded with latticed alloy, the latticed alloy is mutually connected with alloy of the scraper edge, and the scraper body is made from manganese steel or common carbon steel. Compared with the prior art, the scraper takes the manganese steel or the common carbon steel as the base body thereof, and welds a composite chrome carbide and niobium carbide alloy on the surface of the base body as a wear-resisting layer, so that the wear-resisting property of the scraper is improved by 2-3 times compared with that of the conventional cast scraper. The scraper has the simple structure, eliminates the complex casting technology, shortens the production period, improves the anti-fragmentation property and the wear-resisting property thereof, and prolongs the service life thereof.
Description
Technical field
The present invention relates to scraper, especially a kind of scraper that is used for concrete mixer.
Background technology
At present, the scraper of existing concrete mixer generally all is cast members such as cast iron or cast steel, and this casting scraper need pass through operations such as die sinking, smelting, casting when making, the manufacturing process complexity, and the production cycle is long, and cost is higher.Though the anti-wear performance of casting scraper is than common A3 steel height, because its material itself, the casting scraper is when being subjected to greater impact power or sharp pounding, and is easier to be more cracked than common A3 steel, thus the service life that can reduce scraper.
Summary of the invention
At the deficiency of above existing concrete mixer scraper, the purpose of this invention is to provide a kind of employing manganese steel or ordinary carbon steel and make matrix, and be welded with the scraper of wear-resistant material layer at matrix surface.
The objective of the invention is by realizing by the following technical solutions:
A kind of scraper comprises and scrapes cutter hub, and an end of scraping cutter hub is provided with scrapes the edge of a knife, and the other end is provided with handle of a knife, and the described outer surface of scraping the edge of a knife is provided with wear-resistant material layer.
As the preferred technical solution of the present invention, the described outer surface of scraping the edge of a knife is welded with one deck wear resistant alloy material.
As the preferred technical solution of the present invention, described wear resistant alloy material is compound carbonizing chromium and niobium carbide alloy.
As the preferred technical solution of the present invention, the two sides of describedly scrape the edge of a knife, scraping cutter hub and handle of a knife are welded with compound carbonizing chromium and niobium carbide alloy.
As the preferred technical solution of the present invention, the described edge of a knife of scraping all is wrapped in the wear resistant alloy material layer.
As the preferred technical solution of the present invention, the described compound carbonizing chromium of scraping cutter hub and handle of a knife two sides and niobium carbide alloy are made as latticed, and this latticed alloy connects with the alloy phase of scraping the edge of a knife.
As the preferred technical solution of the present invention, the surface of described handle of a knife has two hexagon through holes.
As the preferred technical solution of the present invention, the described material of scraping cutter hub is manganese steel or ordinary carbon steel.
The invention has the beneficial effects as follows: with respect to prior art, the present invention adopts manganese steel or ordinary carbon steel to make the matrix of scraper, and is welded with compound carbonizing chromium and niobium carbide alloy as wearing layer at matrix surface, improves 2-3 doubly than the anti-wear performance of conventional cast scraper.The present invention is simple in structure, has not only removed complex casting technology from, has shortened the production cycle, and has improved the chip resistant performance and the anti-wear performance of scraper, has prolonged the service life of scraper.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of scraper comprises and scrapes cutter hub 1 that the material of scraping cutter hub 1 is manganese steel or ordinary carbon steel.An end of scraping cutter hub 1 is provided with scrapes the edge of a knife 11, and the other end is provided with handle of a knife 12, and the described outer surface of scraping the edge of a knife 11 is provided with wear-resistant material layer.
In the present embodiment, the described wear-resistant material layer of scraping the edge of a knife 11 outer surfaces is to adopt compound carbonizing chromium and niobium carbide alloy welding wire to be welded to scrape on the edge of a knife 11, and compound carbonizing chromium and niobium carbide alloy-layer 2 will be scraped the edge of a knife 11 and all wrap up.Described two sides of scraping cutter hub 1 and handle of a knife 12 are welded with latticed compound carbonizing chromium and niobium carbide alloy-layer 3; alloy-layer 3 interconnects with the alloy-layer 2 of scraping the edge of a knife 11; form integrally-built latticed compound carbonizing chromium and niobium carbide alloy-layer; thereby general protection is scraped cutter hub 1 and is scraped the edge of a knife 11, improves the anti-wear performance of scraper.
The surface of the described handle of a knife 12 of present embodiment has two hexagon through holes 4, and this through hole 4 is that the bolt hole that connects scraper is installed.The present invention adopts manganese steel or ordinary carbon steel to make the matrix of scraper, make wearing layer at matrix surface welding compound carbonizing chromium and niobium carbide alloy, anti-wear performance than conventional cast scraper improves about 2-3 times, improves the chip resistant performance of scraper simultaneously, prolongs the service life of scraper.
