Description

Conveyer belt rubber torsional spring alloy sweeper

Technical field

The present invention relates to the adhesive tapes conveying technology fields such as power station, harbour, mine, and in particular to a kind of conveyer belt rubber torsional spring Alloy sweeper, for being cleaned to the easily viscous coal slime of high viscosity on conveyer belt, sludge, foreign matter etc..

Background technique

Belt conveyor is the major way of the industries delivery of bulk material such as power station, harbour, mine, and conveyer belt is that material is defeated Send transport process most popular conveying device.

Traditional sweeper scraper use elastic polyurethane material, scraper be easy to produce in cleaning process frictional heat and Endogenous heat influences polyurethane elastomer hardness, and after scraper hardness reduces, the easily viscous material particles of high viscosity pierce conveyer belt Among scraper, scraper is caused to separate with conveyer belt, can not effectively remove viscous material on the conveyor belt, viscous material bed meeting Roller and carrying roller buildup are caused, roller is non-round, and belt deviation skids, and design requirement is not achieved in transport power.After belt is dry, with Belt operation, the viscous material bed shape that fragmentates fall off, and cause conveyer belt spreading on the way, clean difficulty.Meanwhile traditional sweeper There is abrasion in scraper, to guarantee that service life scraper volume is larger, often due to causing nothing when the locational space deficiency of sweeper installation Method is installed and used.

Summary of the invention

The technical problem to be solved by the present invention is to it is empty to provide a kind of installation for existing sweeper above shortcomings Between the small conveyer belt rubber torsional spring alloy sweeper of demand, it is ensured that conveyor belt high-speed transfer of highly viscous easily viscous material when it is clear It sweeps completely, and guarantees scraper long service life.

The present invention to solve above-mentioned technical problem the technical solution adopted is that:

Conveyer belt rubber torsional spring alloy sweeper, including secured adjusted component, doctor blade holder, doctor unit, the fixed tune Section component is mounted on conveyer belt middle frame channel steel, and the doctor blade holder both ends are mounted on secured adjusted component；It is described to scrape Knife rest includes scraping cutter bar, long axle sleeve and short sleeve, and the long axle sleeve and short sleeve are each perpendicular to scraping cutter bar axis direction and alternating It is arranged on scraping cutter bar in the same level of the same side；The doctor unit includes that scraper, scraper base, torsion shell and rubber are turned round Spring, torsion shell are mounted in long axle sleeve or short sleeve that (doctor unit interlocks by reversing housing retaining screws and axle sleeve end cap Arranged superposed is in scraping cutter bar side), rubber torsional spring is fixed in torsion shell, and scraper base is fixed in rubber torsional spring, is scraped The knife handle of knife is fixed on scraper base.

According to the above scheme, multiple screws are set on the secured adjusted component and the cooperation of conveyer belt middle frame channel steel connects It connects, the screw by adjusting secured adjusted component realizes the adjustment of doctor blade holder height and angle.

According to the above scheme, the rubber torsional spring of the doctor unit is radial and torsion shell cooperation is fixed, axially through sealing Ring and sealing cover are fixed, and scraper base is fixed on the interior square tube of rubber torsional spring by the fixed end cap of scraper base and scraper base fixing screws Kong Zhong, scraper base are provided with the stepped hole being cooperatively connected with scraper；The scraper includes cutter head, knife bar and knife handle, the knife of cutter head Carbide chip is inlaid on mouthful, knife bar connects cutter head and knife handle, the threaded hole of fastening scraper knife handle is offered on scraper base, Knife handle is fixed in the stepped hole of scraper base by scraper fixing bolt and nut.

According to the above scheme, the doctor unit further includes scraper anti-drop end cover, and scraper anti-drop end cover is fixed by screws in On knife handle, and disengaging when preventing scraper from loosening by the stepped hole on scraper base.

According to the above scheme, the convex-concave seam allowance worked in coordination, convex-concave are provided on the torsion shell and long axle sleeve, short sleeve Seam allowance prevents doctor unit from rotating.

According to the above scheme, the long axle sleeve, short sleeve have certain distance on perpendicular to scraping cutter bar axis direction, guarantee to scrape The scraper top surface of knife unit (guarantees that scraper movement will not interfere) all in the same plane, and long axle sleeve, short sleeve Interlaced arrangement spacing is less than blade width, guarantees that doctor unit overlapped certain distance on scraping cutter bar axis direction (guarantees Full blade face realizes scraper).

The present invention compared with traditional polyurethane blade sweeper the utility model has the advantages that

1, there is outstanding dynamic compensation performance using the scraper of rubber torsional spring elastic element driving, while inlays hard conjunction The scraper of golden blade material easily viscous for high belt speed high viscosity has excellent wear-resisting and scraper performance, the tracking to conveyer belt Property is more preferable, and material is not easy to get between scraper and adhesive tape, and cutter head is not easy buildup, will not generate the viscous phenomenon of material；

2, scraper has high fine-tuning function, and the screw by adjusting secured adjusted component realizes doctor blade holder height and angle Adjustment, pass through and adjust scraper fixing bolt and nut, realize the orientation anti-rotation adjustment of doctor unit height；Scraper top surface all and Belt contacts, realize scraper and belt etc. contact forces, guarantee that full blade face realizes scraper, the service life is longer.

3, doctor unit is arranged using vertical scraping knife bar and adhesive tape parallel surface, reduces washer installation footprint, energy For narrow installation site, applicable surface is wider.
