Abstract

The utility model relates to a clamped hard metals cleaning scraper, comprising a press plate (1), a hard metals scraping slice (2) and a scraper body (3) which are fastened by screws. The clamped hard metals cleaning scraper is characterized in that two edges of the hard metals scraping slice (2) are both used for working edges, after one edge is abraded, the user can replace the other edge to use. When the two edges are both abraded, the user can replace a new scraping slice, and the press plate (1) and the scraper body (3) need not to be replaced. Thus, the clamped hard metals cleaning scraper saves the hard metals by 30% as well as improves the availability ratio of the press plate and the scraper body. The clamped hard metals cleaning scraper has convenient disassembly, assembly, maintenance and upkeep. The clamped hard metals cleaning scraper can be installed on various styles of cleaning frame bodies of belt conveyors, and thus, various styles of cleaning devices can be formed.

Description

Clamped hard metals cleaning scraper

The utility model relates to the conveyer clearing apparatus.

Travelling apron is distinct issues to the remaining material that adheres on the cleaning backhaul adhesive tape all the time.Clean untotally, can cause rubber belt from deviating, reduce the service life of adhesive tape.At present the used swabbing pig of travelling apron, mostly adopt rubber plate as scraper cleaner because rubber plate hardness is low, not wear-resisting, the life-span is short, period of service elder half a year, weak point person only 2～3 months just damage scrap.

For this reason, also there is the Hardmetal materials of employing to make scraper cleaner at present both at home and abroad, its long service life, the cleaning effect might as well.The structural shape of this scraper cleaner all is with the hard alloy scraping blade, be welded to scraping on the plate body of common iron, for guaranteeing weld strength, all to use soldering (silver soldering or brazing), condemnation factor is higher during welding, and every hard alloy scraping blade can only use on one side, and another side is welded in to be scraped in the plate body, after the wearing and tearing of one side of work, can only together scrap replacing together with scraping plate body.Hard alloy scraping blade waste is big like this, and it is also big to scrape the plate body waste, causes the cost height.

The purpose of this utility model provides the two-sided utilization of a kind of hard alloy scraper plate energy, clamping type hard alloy scraper cleaner, the degree of utilization of raising hard alloy scraper plate.

The utility model, design-calculated clamping type hard alloy scraper cleaner, it is clean that it can reach cleaning, long service life, can also make two limits of hard alloy scraping blade all can be used as the working edge use, when changing scraping blade, need not change and scrape plate body and pressing plate, can improve hard alloy scraping blade and the degree of utilization of scraping plate body, cost-cutting, be convenient to dismounting, maintenance, can be installed in again on the cleaning support body of various types, enlarge the range of use of this scraper cleaner.

Content of the present utility model: clamping type hard alloy scraper cleaner, be will make rectangular, two ends have the hard alloy scraping blade of positioning groove, be embedded in and have the pressing plate of locating convex shoulder, one block pressur plate is two scraping blades of embedding side by side, again with the plate body of scraping of angle type or straight type, scraping blade is compressed, with screw they are linked together, form a clamping type hard alloy scraper cleaner, with bolt clamping type hard alloy scraper cleaner and cleaning support body are linked, and the And row are installed some scraper cleaners, form used clearing apparatus on the conveyer, conveyer backhaul adhesive tape is cleaned.The clearing apparatus of each conveyer needs several scraper cleaners are installed, and can decide according to the width B of adhesive tape.This scraper cleaner can also be applicable to the cleaning support body of multiple structural shape, forms the various ways clearing apparatus.

The utility model embodiment: clamping type hard alloy scraper cleaner (hereinafter to be referred as: scraper cleaner) be with pressing plate (1) as shown in Figure 3, scrape plate body (3), by screw, form in the middle of hard alloy scraping blade (2) is fastened on.And whole clearing apparatus (as Fig. 6) is to be combined and cleaned by several or several ten scraper cleaners.What of used scraper cleaner, can decide according to tape width B, as long as the width that makes the scraper cleaner of combining is greater than tape width B, but the working edge of all hard alloy scraping blades (2) that requirement is combined, with the contacted bus of adhesive tape can be on same straight line, cleaning is effective like this, and is little to the damage of adhesive tape, is the key of this scraper cleaner so will solve the location of hard alloy scraping blade (2).

For this reason, pressing plate (1) (as Fig. 8) three convex shoulders 6 have been made, 7,6 and two holes, then on this block pressur plate, can embed two (as Figure 11) length below 100 millimeters, wide about 10 millimeter, thick 2～3 millimeters hard alloy scraping blade (2), at hard alloy scraping blade two ends two positioning grooves are arranged, it is embedded in the convex shoulder 6 of pressing plate, in 7, again another piece hard alloy scraping blade (2) is embedded in 7, in 6 convex shoulders, one block pressur plate can embed two hard alloy scraping blades (2), then these two scraping blades (2) just have a public convex shoulder 7 to do the location, and the working edge that can guarantee to be embedded in the two hard alloy scraping blades (2) on the same block pressur plate (1) is an in-line.And concavo-convex chucking lug 5 is arranged at the two ends of pressing plate (1), this is when the polylith scraper cleaner is combined, this concavo-convex chucking lug 5 can join end to end, after guaranteeing every scraper cleaner combination, the working edge of hard alloy scraping blade (2) can both the in-line (see figure 6).

Scrape plate body (3) (as Fig. 3, Fig. 4) make and have two oval holes, the dihedral of four screws is scraped plate body (3), or make straight shape and scrape plate body (3) (as Figure 15), scrape plate body (3) for one and can allocate two block pressur plates (1) into, just can allocate four hard alloy scraping blades (2) into, with four screws with four hard alloy scraping blades (2), be fastened on pressing plate (1) and scrape between the plate body (3), promptly become clamping type hard alloy scraper cleaner., link by scraping the oval hole on the plate body with bolt with cleaning support body (5), promptly form (as Fig. 6, Fig. 7) spring loaded clearing apparatus.

This scraper cleaner can be easily links with the cleaning support body (5) of various versions, becomes the clearing apparatus of various different structures.Can both reach the clean optimum efficiency of cleaning.

Scraper cleaner can clean outside support body (5) links with spring, also can with caoutchouc elasticity clean support body (5) link (as Figure 12) form the caoutchouc elasticity clearing apparatus.Also scraper cleaner can be installed on the hammer cleaning support body (5) that hangs down, form the hammer clearing apparatus (as Figure 14) that hangs down.Also can make straight shape and (as Figure 15, Figure 16), link (as Figure 13), form tapered caoutchouc elasticity clearing apparatus scraping plate body (3) with cone rubber elasticity support body (5).So this clamping type scraper cleaner can adapt to the cleaning support body (5) of different structure form, forms various forms of clearing apparatus, has enlarged the range of use of clamping type hard alloy scraper cleaner, and the cleaning effect is all fine.

After the working edge wearing and tearing of hard alloy scraping blade (2),, hard alloy scraping blade (2) is changed a working edge re-use as long as screw is pulled down, after a slice hard alloy scraping blade (2) can use secondary like this, scrap, this compares with the welded type scraper cleaner, can save 30% hard alloy again.After if two working edge complete wears of scraping blade are decreased, as long as change a hard alloy scraping blade (2) in addition, and pressing plate (1), scrape plate body (3) and just need not change, still can use, this is harder than welded type
