Description
Technical Field
The utility model relates to the field of power generation, in particular to a scraper device of a belt cleaner of a coal conveyor.
Background
The utility model provides a coal conveyor belt sweeper is the requisite device of coal conveyor for prevent dust adhesion on the belt surface, clean and maintain the belt, extension belt life improves production efficiency and product quality, avoids the occurence of failure, and the pipe of belt sweeper generally adopts polyurethane material to make, has following problem in the polyurethane material use, first, and the material is softer, can't clear away some high dust of viscosity, and second, when the knife tip wearing and tearing, the sweeper can normally precess to the belt, in order to keep the contact between scraper blade and the belt. However, when the resilient blade is mounted too close to the belt, causing the heel of the blade to contact the belt, this "back-tilting" creates a gap between the belt and the nose in which conveyed material is constantly deposited, which forces the blade away from the belt. Once the scraper blade is pushed away from the belt, a large amount of materials can pass through the gap between the belt and the scraper blade, so that abrasion between the scraper blade and the belt is greatly increased, cleaning efficiency is reduced, and thirdly, in order to improve cleaning efficiency, the pressure of the scraper blade of the sweeper to the belt is excessively improved, the cleaning efficiency is reduced, the service life is shortened, and even if the scraper blade is installed correctly, the scraper blade is excessively tensioned, and the force is transferred to the root of the scraper blade from the whole contact area. This results in a "slight back-tilting" situation where material passes between the blade and belt, again resulting in poor cleaning efficiency and increased wear of the blade and belt, and a means is needed to solve the above problems.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides the scraper device of the coal conveyor belt sweeper, which is provided with the metal framework cleaning teeth and the cleaning teeth which are arranged on the outer side of the scraper blade, wherein the cleaning teeth and the belt are at a certain angle and are separated from the belt, so that dust with high viscosity is effectively removed, the strength of the scraper blade is improved, and the scraper blade is prevented from tilting backwards.
The utility model aims at realizing the following technical scheme:
the utility model provides a coal conveyor belt sweeper scraper blade device, includes the scraper blade, the scraper blade is installed in the belt outside, scraper blade outside fixed connection cleans the tooth, clean tooth appearance and scraper blade appearance and adapt to, it has a set of single tooth to clean the tooth, and every single tooth head is equipped with the cutting edge, the cutting edge is big-end-up's conical body, the contact of the scraper blade top portion of cutting edge lower part and scraper blade, certain contained angle is personally submitted with the belt surface to cutting edge portion.
The scraping plate is made of polyurethane materials.
The cleaning teeth are made of metal materials.
The beneficial effects are that: the cleaning teeth of the device are arranged on the outer side of the scraping plate, the lower part of the cutting edge is contacted with the tooth crest part of the scraping plate, the cutting edge part of the cutting edge is in a certain included angle with the surface of the belt, a group of cutting edges firstly divide and cut dust on the outer side of the belt, especially some dust with higher viscosity, flows out along the two sides of the cutting edge, is scraped off from the surface of the belt by the scraping plate again, a process of firstly cutting and then scraping is formed, dust, especially dust with higher viscosity, is easily removed by the cleaning teeth after being cut, the cutting force of the scraping plate is reduced, the dust is more thoroughly removed, the cleaning teeth are made of metal materials, the cleaning teeth have a reinforcing effect on the scraping plate, and the problem of backward tilting of the scraping plate when the scraping plate is worn or the tightening force is overlarge is solved.

Description of the embodiments
The utility model is described in further detail below with reference to the drawings and examples:
referring to fig. 1, 2 and 3, a scraper device of a belt cleaner of a coal conveyor comprises a scraper 110, wherein the scraper 110 is arranged on the outer side of a belt, cleaning teeth 120 are fixedly connected on the outer side of the scraper 110, the shape of each cleaning tooth 120 is matched with that of the scraper 110, each cleaning tooth 120 is provided with a group of single teeth 121, the head of each single tooth 121 is provided with a cutting edge 122, each cutting edge 122 is a cone with a small upper part and a large lower part, the lower part of each cutting edge 122 is contacted with the top of each scraper tooth 111 of the scraper 110, and the cutting edge 122 and the surface of the belt 130 form a certain included angle.
The scraper 110 is made of polyurethane material.
The cleaning teeth 120 are made of a metal material.
The cleaning teeth 120 of the device are arranged on the outer side of the scraper 110, the lower part of the blade 122 is contacted with the top of the scraper teeth 111 of the scraper 110, the blade parts of the blade 122 and the surface of the belt 130 form a certain included angle, one group of blade parts 122 firstly divide and chop dust on the outer side of the belt 130, especially some dust with higher viscosity, flows out along the two sides of the blade 122 by the divided and chopped dust, and then is scraped off from the surface of the belt 130 by the scraper 110 again, so that the process of cutting before scraping is formed, the dust, especially the dust with higher viscosity, is easily removed by the cleaning teeth 120 after being cut, the cutting force of the scraper 110 is reduced, the dust is more thoroughly removed, the cleaning teeth 120 are made of metal materials, the reinforcing effect is provided for the scraper 110, and the problem of backward tilting of the scraper 110 when the scraper 110 is worn or the clamping force is overlarge is solved.
