The utility model relates to a scraper, which belongs to the technical field of concrete mixers and comprises a scraper body. One end of the scraper body is provided with a scraper mouth, and the other end is provided with a handle. The outer surface of the scraper mouth is welded with a layer of composite chromium carbide and niobium carbide alloy. The scraper mouth is completely wrapped in the alloy layer. The scraper body and both sides of the handle are welded with mesh alloy, and the mesh alloy and the alloy of the scraper mouth are connected to each other. The material of the scraper body is manganese steel or ordinary carbon steel. Compared with the prior art, the utility model adopts manganese steel or ordinary carbon steel as the substrate of the scraper, and welds composite chromium carbide and niobium carbide alloy on the surface of the substrate as the wear-resistant layer, which improves the wear resistance of the traditional cast scraper by 2-3 times. The utility model has a simple structure, which not only eliminates the complicated casting process and shortens the production period, but also improves the anti-fragmentation performance and wear resistance of the scraper and prolongs the service life of the scraper.
Description
Technical field
The utility model 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.
The utility model content
At the deficiency of above existing concrete mixer scraper, the purpose of this utility model provides a kind of employing manganese steel or ordinary carbon steel is made matrix, and is welded with the scraper of wear-resistant material layer at matrix surface.
The purpose of this utility model is achieved by the following technical solution:
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 optimal technical scheme of the present utility model, the described outer surface of scraping the edge of a knife is welded with one deck wear resistant alloy material.
As optimal technical scheme of the present utility model, described wear resistant alloy material is compound carbonizing chromium and niobium carbide alloy.
As optimal technical scheme of the present utility model, 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 optimal technical scheme of the present utility model, the described edge of a knife of scraping all is wrapped in the wear resistant alloy material layer.
As optimal technical scheme of the present utility model, 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 optimal technical scheme of the present utility model, the surface of described handle of a knife has two hexagon through holes.
As optimal technical scheme of the present utility model, the described material of scraping cutter hub is manganese steel or ordinary carbon steel.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts manganese steel or ordinary carbon steel to make the matrix of scraper, and be welded with compound carbonizing chromium and niobium carbide alloy as wearing layer at matrix surface, improve 2-3 doubly than the anti-wear performance of conventional cast scraper.The utility model 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 utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a structural representation of the present utility model.
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 utility model 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.
