Description
Technical field
The utility model relates to a kind of to industrial sweeper, particularly is used in the improvement of the clearing apparatus structure on the ribbon conveyer.
Background technology
The material that conveyer belt is carried often has stickum, and as coal dust, granular material etc., wherein a part can be bonded on the conveyer belt working face, enters easily when discharging in the snub pulley and carrying roller housing of unloaded section, and bearing is worn and torn fast; The carrying roller housing is stained with material and can tears and plucking conveying zone face glue, quickens the wearing and tearing of conveyer belt.If adhesion enters tail changed course cylinder or vertical tension drum, will be bonded on the cylinder surface, cause belt deflection, increase the wearing and tearing of conveyer belt, even tear the drum rubber layer, cause serious consequence.So the cleaning ability of clearing apparatus reduces equipment failure rate and has very important effect with the reduction maintenance cost improving operational efficiency, the reliability of ribbon conveyer on the ribbon conveyer.
What at present domestic most of belt cleaners adopted is the acacia gum sweeper, it adopts rubber as elastomer alloy cleaning scraper to be pressed on the belt surface, this sweeper has characteristic of simple structure, but it also has fatal shortcoming, the solid accumulation that cleans exactly is on cleaning board and elastomer, fall to increase elastomeric absorbing effect influence cleaning effect and service life as untimely cleaning; The elastomer overlong time can produce ageing of rubber, and elasticity attenuation comes unglued, bolt looseness phenomenon such as come off, and can scratch belt; This sweeper is not offset the cutter relieving function, because what adopt is carbide alloy cleaning scraper, when running into protrusion such as bulk resistance and conveying band joint, is easy to hurt belt.
Technology contents
The purpose of this utility model is, a kind of elastic scraper formula sweeper is provided, so solved in the background technology sweeper elastomer service life short, fragile, hurt problems such as belt easily.
The utility model is realized in the following manner: in the described elastic scraper formula sweeper structure, angle steel is fixed on the square steel tube, tubular axis in angle steel, square steel tube and the square steel tube constitutes the swing pedestal, insert in the slot of swing pedestal upper surface formation the lower end of scraper plate, and two ends are respectively arranged with the block of bolting on the swing pedestal.Described scraper plate be shaped as arc-shaped curved surface; Be respectively arranged with a tensioning apparatus at the two ends of described swing pedestal.
Ring flange is fixed on the square steel tube that exposes at described swing pedestal two ends by bearing block, an end of swing arm is fixed on the ring flange in the described tensioning apparatus, and the other end has an elastic regulating structure that is made of the nut of the spring on spring pressure bar, spring base, the spring pressure bar, spring pressure bar end with bolting.
The outside of described tensioning apparatus, the two ends of described swing pedestal are respectively arranged with ripping bar.
With process that belt contacts in, even the arc-shaped curved surface of scraper plate profile also can keep the basil preferably after the scraper plate wearing and tearing, can effectively strike off the material that sticks on the belt, and need not often adjust.In tensioning apparatus, owing to adopted the tensioning apparatus of spring structure, make the swing pedestal have the function of automatic compensation and damping, and can keep stable contact pressure, can improve the scraper plate life-span and improve the cleaning effect.
Said structure of the present utility model has following advantage:
1. simple installation is quick; Compact conformation is adjusted easy to maintenancely, and it is little to take up room.
2. scraper plate wearability, shock resistance are good, and the scraper plate coefficient of friction is low, the little or almost not damage to the belt damage; Be applicable to bad working environments and high belt speed operating mode, long service life;
3. scraper plate in use has the sharp keen characteristic of the automatic maintenance scraper plate basil, cleans effective;
4. scraper plate adopts the design of sectional type mold, and versatility is good, and it is convenient to change, and maintenance cost is low;
5. tensioning apparatus adopts spring take-up, has tensioning and buffering absorbing effect simultaneously, can guarantee the thorough and stable of cleaning, and can prolong the service life of scraper plate.
